‘Exciting’ new gene therapy yields promising results
In the first-in-human, phase 1 open-label study, known as ANTLER, 5 out of 5 patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL) responded to a single dose of CB-010, an allogeneic CAR-T cell therapy designed to boost antitumor activity, according to the company.
The use of chimeric antigen receptor (CAR) T-cell therapy involves taking T cells out of the body, reprogramming them with CAR to better equip them to kill cancer cells, and putting them back into the body.
The study consists of two sections: an initial dose escalation following a 3 + 3 design, with prespecified, increasing doses, followed by an expanded trial in which all patients receive CB-010 at the dose determined in the first section.
The study population included 6 adults with r/r B-NHL who had relapsed after previous treatment with a median of 3 prior therapies. At baseline, all 6 patients underwent a lymphodepletion regimen consisting of cyclophosphamide at 60 mg/kg/day for 2 days, followed by 5 days of fludarabine at 25 mg/m2/day.
Then all patients received a single dose of 40x106 CAR-T cells. As of the Feb. 23, 2022, data cutoff date, 5 of the 6 patients had completed the 28-day dose-limiting toxicity (DLT) evaluation period. All 5 patients (100%) achieved a response; 4 achieved complete response and 1 achieved partial response. All 4 of the complete responders had ongoing complete response at 3 months, and the longest measured complete response was 6 months, according to the company.
“We are excited to see a 100% overall response rate with CB-010 at dose level 1 for these patients who have limited treatment options,” said Dr. Syed Rizvi, chief medical officer for Caribou Biosciences, in the press release. “We believe this initial level of activity is unparalleled for a single, starting dose of cell therapy. CB-010 was generally well-tolerated, with adverse events routinely observed in autologous or allogeneic anti-CD19 CAR-T cell therapies,” he said.
Based on the promising safety and efficacy results, the company is enrolling patients in a second cohort for treatment at dose level 2 (80x106 CAR-T cells), according to the news release.
Another allogeneic CAR-T cell therapy known as ALLO-501A is being studied in a similar trial conducted by the Moffitt Cancer Center.
Overall, CB-010 was well-tolerated, according to Caribou Biosciences. No cases of graft-versus-host disease were reported. A total of 3 patients developed grade 3 or 4 adverse events (AEs) within the first 28 days; the most common were neutropenia (50%), thrombocytopenia (33%), anemia (17%), and hypogammaglobulinemia (17%). One patient experienced both grade 1 cytokine release syndrome (CRS) and grade 3 Immune effector cell-Associated Neurotoxicity Syndrome (ICANS). This response was characterized as a dose-limiting toxicity. The patient was treated with tocilizumab and steroids, recovered within 39 hours, and went on to achieve a complete response, according to the company.
Although the safety profile in the current study was promising, prior research suggest that concerns associated with CRS and ICANS should not be ignored and may be barriers to treatment.
In an article published in Bone Marrow Transplant in 2021, Dr. Vipul Sheth and Dr. Jordan Gauthier of the Fred Hutchinson Cancer Center, Seattle, noted that adverse effects may remain a challenge to widespread use of CAR-T in patients with refractory or relapsed acute lymphoblastic leukemia, for which it has been approved by the U.S. Food and Drug Administration and several European agencies. However, “there is mounting evidence that earlier, and potentially more targeted, interventions can reduce these toxicities,” they wrote.
Study provides solid stepping stone
“CRS and ICANS are mild in most patients but can be severe and sometimes life-threatening in a subset of patients undergoing CD19 CAR T-cell therapy,” Dr. Gauthier said in an interview. “Different strategies are being investigated to mitigate or treat severe toxicities, such as the use of prophylactic corticosteroids, anakinra, lenzilumab, itacitinib. I am hopeful we will soon manage to prevent toxicities while maintaining potent anti-tumor effects,” he said.
“While autologous CD19 CAR-T cells have high efficacy in patients with refractory/relapsed large B-cell lymphoma, product manufacturing remains a complicated and lengthy process in the autologous setting,” Dr. Gauthier noted. “Commercial CAR T-cell manufacturing takes approximately 3-4 weeks, sometimes longer. Some patients won’t survive long enough to receive their infusion. In some patients, T-cell function is dramatically impaired, due to prior therapies or to the disease itself,” he said.
Dr. Gauthier said he was not surprised but that he was encouraged by the apparent early success of the ANTLER study. “The proof-of-concept that allogeneic CD19-targeted CAR T cells can induce high response rates in r/r LBCL has already been established,” he said. “Having said that, it is comforting to see prior findings confirmed by this new study, and those results are exciting for the field,” he added.
As for additional research, “we need longer follow-up after allogeneic CD19-targeted CAR T-cell therapy to ensure responses are durable,” Dr. Gauthier explained. “We also need to better understand the biology driving the antitumor effects and the side effects of CAR T-cells. This will help us build more efficacious and safer CAR T-cell therapies,” he said.
Response and side effects show promise for future research
The therapy is “the best CAR-T product” that clinicians can provide for patients knowing that autologous CAR-T works, said Dr. Ahmed Galal, of Duke University, Durham, N.C., in an interview. The current research supports the use of this treatment immediately for patients, he added.
Dr. Galal said he was somewhat surprised, but pleasantly so, by the 100% response rate. This rate is likely because of the small number of patients and may not hold up in further research, but “even 90% would be an amazing achievement,” he said. The tolerable safety profile is encouraging as well, he emphasized. Dr. Galal said that he did not foresee any real barriers to expanded use of the therapy and that technology should make it easier to deliver at authorized centers.
Limitations to the current study are those common to all phase 1 trials, such as the strict inclusion criteria, Dr. Galal said. As research progresses to phase 2, “I don’t think it will be an obstacle to find patients,” he said. However, patients should be aware of side effects, and clinicians should maintain a culture of education to help them understand the value of the therapy, he added.
The complete data from the preliminary findings are scheduled to be presented at the European Hematology Association (EHA) 2022 Hybrid Congress, Vienna, in June, as abstract P1455, titled “First-in-human trial of CB-010, a CRISPR-edited allogeneic anti-CD19 CAR-T cell therapy with a PD-1 knock out, in patients with relapsed or refractory B cell non-Hodgkin lymphoma (ANTLER study).” The findings are scheduled to be presented by Loretta J. Nastoupil, MD, of the University of Texas MD Anderson Cancer Center, according to Caribou Biosciences.

‘Very impressive’ data promise new blood cancer option
“We have limited treatment options for triple-class exposed and refractory multiple myeloma patients, especially for use in the community,” coauthor Dr. Saad Z. Usmani, of Memorial Sloan Kettering Cancer Center, New York, said in an interview. “Teclistamab is a BCMA directed bispecific antibody that is showing high response rates at the recommended subcutaneous phase 2 doses (RP2D),” and has a strong safety profile, he explained.
Teclistamab tackles two targets – both CD3 on the surface of T cells and B-cell maturation antigen (BCMA) on the surface of myeloma cells – said Dr. Ajay K. Nooka of Emory University, Atlanta, in the meeting presentation. The study was published simultaneously in the New England Journal of Medicine.
After teclistamab showed promising efficacy and an acceptable level of side effects in phase 1, researchers enrolled 165 adults aged 33-84 years with relapsed or refractory multiple myeloma (MM). The patients had experienced at least three previous lines of therapy (LOT). All patients received a weekly subcutaneous injection of 1.5 mg/kg of body weight following step-up doses of 0.06 mg/kg and 0.3 mg/kg. The primary endpoint of the study was overall response.
The median age of the patients was 64 years; 58% were male, 81.2% were White. The median prior LOT was 5; all of the patients were triple-class exposed (100%); 70% were penta-drug exposed, 78% were triple-class refractory, and 30% penta-drug refractory.
The overall response rate (ORR) was 63% over a median follow-up period of approximately 14.1 months. In addition, 39.4% of patients had a complete response or better, and 26.7% had no minimal residual disease, for a negative minimal residual disease rate of 46.2% in patients with complete response. The median durations of response and progression-free survival were 18.4 months and 11.3 months, respectively.
“The ORR was consistent across clinically relevant subgroups, including high cytogenetic risk and penta-drug refractory subgroups,” Dr. Nooka said in his presentation.
The most common adverse event was cytokine release syndrome, which occurred in 72.1% of patients; however, only 0.6% of these events were grade 3, and none were grade 4. Other adverse events included neutropenia in 70.9% (64.2% of events were grade 3 or 4), anemia (52.1%, 37.0% of events were grade 3 or 4, respectively) and thrombocytopenia (40%, 21.2% of events were grade 3 or 4). Infections occurred in 76.4% of patients overall, 44.8% of which were grade 3 or 4, and neurotoxic events occurred in 24 patients (14.5%). The five cases of immune effector cell–associated neurotoxicity syndrome (CRS) were grade 1 or 2.
A total of 2 patients (1.2%) discontinued the study because of adverse events, but no discontinuations or dose reductions occurred as a result of neurotoxic events.
A total of 5 deaths attributed to teclistamab occurred during the study: 2 caused by COVID-19, 1 pneumonia, 1 hepatic failure, and 1 progressive multifocal leukoencephalopathy (PML).
The responses were durable and persisted over time, said Dr. Nooka. At the point of data cutoff, 64.4% of patients who responded maintained that response.
Overall, the data support teclistamab as “a promising new, off-the-shelf, T-cell redirecting therapy targeting BCMA for patients with relapsed or refractory MM,” with phase 3 studies ongoing and early access programs in progress, Dr. Nooka concluded.
“The ORR and durability of response seen with teclistamab is very impressive when one sees the data for other single agents approved for relapsed/refractory MM in the past,” Dr. Usmani said in an interview. “I hope the current data will help get a regulatory approval for the triple class exposed MM population.”
However, potential barriers to widespread use of teclistamab in practice include logistics and a learning curve for practicing hematologists/oncologists, Dr. Usmani noted. “While the CRS appears to be grade 1 or 2 and very manageable, the logistics of giving bispecific antibodies in the community setting and managing CRS during the first cycle of therapy in the community will need to be worked out, and partnership with academic centers that have experience in managing these patients will be needed, he added.
As for additional research, “teclistamab is being combined with other MM therapies and being explored in earlier lines of treatment,” Dr. Usmani said.
Be ready to manage infections
Despite promising early findings, the use of teclistamab and other BCMA-targeting biospecific therapies is “not a free lunch” for refractory and relapsed MM patients, said discussant Dr. Madhav V. Dhodapkar of Emory University, Atlanta, during the discussion period after the ASCO presentation.
Although the risk of CRS and ICANS appears low, “infections are emerging as a major adverse event” that need to be recognized and managed, he said.
A distinct pattern of infections may be emerging, based on data from the current study and other studies of similar therapies, with infections such as Pneumocystis jirovecii (PJP) and cytomegalovirus (CMV) reactivation, Dr. Dhodapkar added.
He noted other considerations for studies of teclistamab and similar therapies, including the need to address both host-related and tumor-related factors, as well as seasonal and opportunistic threats such as COVID-19.
Future research questions include whether there is a role for pathogen-specific surveillance to help mitigate infection risk, including COVID-19 risk management strategies, he emphasized.
The study was funded by Janssen Research and Development.
Dr. Usmani disclosed relationships as a consultant or advisor, speakers’ bureau member, and/or recipient of research funding from serving as a consultant or advisor for Abbvie, Amgen, Bristol-Myers Squibb/Celgene, Celgene, Genentech, Gilead Sciences, GlaxoSmithKline, Janssen Oncology, Karyopharm Therapeutics, Merck, Oncopeptides, Seattle Genetics, Skyline Diagnostics, and Takeda. Lead author of the New England Journal paper Dr. Philippe Moreau disclosed relationships with companies including Abbvie, Amgen, Celgene, GlaxoSmithKline, Janssen-Cilag, Oncopeptides, and Sanofi. ASCO presenting author Dr. Nooka disclosed relationships with companies including Adaptive Biotechnologies, Amgen, BeyondSpring Pharmaceuticals, Bristol-Myers Squibb/Celgene, Genzyme, GlaxoSmithKline, Janssen Oncology, Karyopharm Therapeutics, Oncopeptides, Secura Bio, Arch Oncology, and Takeda.

Future research questions include whether there is a role for pathogen-specific surveillance to help mitigate infection risk, including COVID-19 risk management strategies, he emphasized.

“We have limited treatment options for triple-class exposed and refractory multiple myeloma patients, especially for use in the community,” coauthor Dr. Saad Z. Usmani, of Memorial Sloan Kettering Cancer Center, New York, said in an interview. “Teclistamab is a BCMA directed bispecific antibody that is showing high response rates at the recommended subcutaneous phase 2 doses (RP2D),” and has a strong safety profile, he explained.
Teclistamab tackles two targets – both CD3 on the surface of T cells and B-cell maturation antigen (BCMA) on the surface of myeloma cells – said Dr. Ajay K. Nooka of Emory University, Atlanta, in the meeting presentation. The study was published simultaneously in the New England Journal of Medicine.
After teclistamab showed promising efficacy and an acceptable level of side effects in phase 1, researchers enrolled 165 adults aged 33-84 years with relapsed or refractory multiple myeloma (MM). The patients had experienced at least three previous lines of therapy (LOT). All patients received a weekly subcutaneous injection of 1.5 mg/kg of body weight following step-up doses of 0.06 mg/kg and 0.3 mg/kg. The primary endpoint of the study was overall response.
The median age of the patients was 64 years; 58% were male, 81.2% were White. The median prior LOT was 5; all of the patients were triple-class exposed (100%); 70% were penta-drug exposed, 78% were triple-class refractory, and 30% penta-drug refractory.
The overall response rate (ORR) was 63% over a median follow-up period of approximately 14.1 months. In addition, 39.4% of patients had a complete response or better, and 26.7% had no minimal residual disease, for a negative minimal residual disease rate of 46.2% in patients with complete response. The median durations of response and progression-free survival were 18.4 months and 11.3 months, respectively.
“The ORR was consistent across clinically relevant subgroups, including high cytogenetic risk and penta-drug refractory subgroups,” Dr. Nooka said in his presentation.
The most common adverse event was cytokine release syndrome, which occurred in 72.1% of patients; however, only 0.6% of these events were grade 3, and none were grade 4. Other adverse events included neutropenia in 70.9% (64.2% of events were grade 3 or 4), anemia (52.1%, 37.0% of events were grade 3 or 4, respectively) and thrombocytopenia (40%, 21.2% of events were grade 3 or 4). Infections occurred in 76.4% of patients overall, 44.8% of which were grade 3 or 4, and neurotoxic events occurred in 24 patients (14.5%). The five cases of immune effector cell–associated neurotoxicity syndrome (CRS) were grade 1 or 2.
A total of 2 patients (1.2%) discontinued the study because of adverse events, but no discontinuations or dose reductions occurred as a result of neurotoxic events.
A total of 5 deaths attributed to teclistamab occurred during the study: 2 caused by COVID-19, 1 pneumonia, 1 hepatic failure, and 1 progressive multifocal leukoencephalopathy (PML).
The responses were durable and persisted over time, said Dr. Nooka. At the point of data cutoff, 64.4% of patients who responded maintained that response.
Overall, the data support teclistamab as “a promising new, off-the-shelf, T-cell redirecting therapy targeting BCMA for patients with relapsed or refractory MM,” with phase 3 studies ongoing and early access programs in progress, Dr. Nooka concluded.
“The ORR and durability of response seen with teclistamab is very impressive when one sees the data for other single agents approved for relapsed/refractory MM in the past,” Dr. Usmani said in an interview. “I hope the current data will help get a regulatory approval for the triple class exposed MM population.”
However, potential barriers to widespread use of teclistamab in practice include logistics and a learning curve for practicing hematologists/oncologists, Dr. Usmani noted. “While the CRS appears to be grade 1 or 2 and very manageable, the logistics of giving bispecific antibodies in the community setting and managing CRS during the first cycle of therapy in the community will need to be worked out, and partnership with academic centers that have experience in managing these patients will be needed, he added.
As for additional research, “teclistamab is being combined with other MM therapies and being explored in earlier lines of treatment,” Dr. Usmani said.
Be ready to manage infections
Despite promising early findings, the use of teclistamab and other BCMA-targeting biospecific therapies is “not a free lunch” for refractory and relapsed MM patients, said discussant Dr. Madhav V. Dhodapkar of Emory University, Atlanta, during the discussion period after the ASCO presentation.
Although the risk of CRS and ICANS appears low, “infections are emerging as a major adverse event” that need to be recognized and managed, he said.
A distinct pattern of infections may be emerging, based on data from the current study and other studies of similar therapies, with infections such as Pneumocystis jirovecii (PJP) and cytomegalovirus (CMV) reactivation, Dr. Dhodapkar added.
He noted other considerations for studies of teclistamab and similar therapies, including the need to address both host-related and tumor-related factors, as well as seasonal and opportunistic threats such as COVID-19.
Future research questions include whether there is a role for pathogen-specific surveillance to help mitigate infection risk, including COVID-19 risk management strategies, he emphasized.

Hospital medicine gains popularity among newly minted physicians
In a new study, published in Annals of Internal Medicine, researchers from ABIM reviewed certification data from 67,902 general internists, accounting for 80% of all general internists certified in the United States from 1990 to 2017.
The researchers also used data from Medicare fee-for-service claims from 2008-2018 to measure and categorize practice setting types. The claims were from patients aged 65 years or older with at least 20 evaluation and management visits each year. Practice settings were categorized as hospitalist, outpatient, or mixed.
“ABIM is always working to understand the real-life experience of physicians, and this project grew out of that sort of analysis,” lead author Bradley M. Gray, PhD, a health services researcher at ABIM in Philadelphia, said in an interview. “We wanted to better understand practice setting, because that relates to the kinds of questions that we ask on our certifying exams. When we did this, we noticed a trend toward hospital medicine.”
Overall, the percentages of general internists in hospitalist practice and outpatient-only practice increased during the study period, from 25% to 40% and from 23% to 38%, respectively. By contrast, the percentage of general internists in a mixed-practice setting decreased from 52% to 23%, a 56% decline. Most of the physicians who left the mixed practice setting switched to outpatient-only practices.
Among the internists certified in 2017, 71% practiced as hospitalists, compared with 8% practicing as outpatient-only physicians. Most physicians remained in their original choice of practice setting. For physicians certified in 1999 and 2012, 86% and 85%, respectively, of those who chose hospitalist medicine remained in the hospital setting 5 years later, as did 95% of outpatient physicians, but only 57% of mixed-practice physicians.
The shift to outpatient practice among senior physicians offset the potential decline in outpatient primary care resulting from the increased choice of hospitalist medicine by new internists, the researchers noted.
The study findings were limited by several factors, including the reliance on Medicare fee-for-service claims, the researchers noted.
“We were surprised by both the dramatic shift toward hospital medicine by new physicians and the shift to outpatient only (an extreme category) for more senior physicians,” Dr. Gray said in an interview.
The shift toward outpatient practice among older physicians may be driven by convenience, said Dr. Gray. “I suspect that it is more efficient to specialize in terms of practice setting. Only seeing patients in the outpatient setting means that you don’t have to travel to the hospital, which can be time consuming.
“Also, with fewer new physicians going into primary care, older physicians need to focus on outpatient visits. This could be problematic in the future as more senior physicians retire and are replaced by new physicians who focus on hospital care,” which could lead to more shortages in primary care physicians, he explained.
The trend toward hospital medicine as a career has been going on since before the pandemic, said Dr. Gray. “I don’t think the pandemic will ultimately impact this trend. That said, at least in the short run, there may have been a decreased demand for primary care, but that is just my speculation. As more data flow in we will be able to answer this question more directly.”
Next steps for research included digging deeper into the data to understand the nature of conditions facing hospitalists, Dr. Gray said.
Implications for primary care
“This study provides an updated snapshot of the popularity of hospital medicine,” said Bradley A. Sharpe, MD, of the division of hospital medicine at the University of California, San Francisco. “It is also important to conduct this study now as health systems think about the challenge of providing high-quality primary care with a rapidly decreasing number of internists choosing to practice outpatient medicine.” Dr. Sharpe was not involved in the study.
“The most surprising finding to me was not the increase in general internists focusing on hospital medicine, but the amount of the increase; it is remarkable that nearly three quarters of general internists are choosing to practice as hospitalists,” Dr. Sharpe noted.
“I think there are a number of key factors at play,” he said. “First, as hospital medicine as a field is now more than 25 years old, hospitals and health systems have evolved to create hospital medicine jobs that are interesting, engaging, rewarding (financially and otherwise), doable, and sustainable. Second, being an outpatient internist is incredibly challenging; multiple studies have shown that it is essentially impossible to complete the evidence-based preventive care for a panel of patients on top of everything else. We know burnout rates are often higher among primary care and family medicine providers. On top of that, the expansion of electronic health records and patient access has led to a massive increase in messages to providers; this has been shown to be associated with burnout.”
The potential impact of the pandemic on physicians’ choices and the trend toward hospital medicine is an interested question, Dr. Sharpe said. The current study showed only trends through 2017.
“To be honest, I think it is difficult to predict,” he said. “Hospitalists shouldered much of the burden of COVID care nationally and burnout rates are high. One could imagine the extra work (as well as concern for personal safety) could lead to fewer providers choosing hospital medicine.
“At the same time, the pandemic has driven many of us to reflect on life and our values and what is important and, through that lens, providers might choose hospital medicine as a more sustainable, do-able, rewarding, and enjoyable career choice,” Dr. Sharpe emphasized.
“Additional research could explore the drivers of this clear trend toward hospital medicine. Determining what is motivating this trend could help hospitals and health systems ensure they have the right workforce for the future and, in particular, how to create outpatient positions that are attractive and rewarding,” he said.
The study received no outside funding. The researchers and Dr. Sharpe disclosed no relevant financial relationships.

Mother’s distress disrupts fetal brain development
Babies of mothers who experience significant psychological distress during pregnancy showed evidence of altered brain development in utero and reduced cognitive outcomes at 18 months, based on data from a pair of studies including approximately 300 women.
In a longitudinal study published in JAMA Network Open, Yao Wu, PhD, of Children’s National Hospital, Washington, and colleagues recruited 97 healthy mother-infant dyads between January 2016 and October 2020 at a single center. Of these, 87 underwent two fetal brain imaging studies each, and 10 completed the first MRI visit, for a total of 184 fetal MRIs.
Neurodevelopment and social-emotional development for infants at 18 months of age was measured using the Bayley Scales of Infant and Toddler Development and Infant-Toddler Social and Emotional Assessment. The mean age of the mothers was 35 years; maternal distress was assessed between 24 and 40 weeks’ gestation using validated self-report questionnaires. Parenting stress was assessed at the 18-month infant testing using the Parenting Stress Index-Short Form.
Overall, prenatal maternal stress was negatively associated with infant cognitive performance (P = .01) at 18 months, mediated by fetal left hippocampal volume.
In addition, increased fetal cortical local gyrification index and sulcal depth measured during reported times of prenatal maternal distress were associated with significantly poorer social-emotional scores and competence scores at age 18 months. The beta coefficients for local gyrification index and sulcal depth were –54.62 and –14.22, respectively, for social-emotional and competence scores, –24.01 and –7.53, respectively; P values were P < .001, P < .002, P = .003, P < .001, respectively.
“Increased cortical gyrification has been suggested in children with dyslexia and autism, and sulcal depth has been associated with the severity of impaired performance on working memory and executive function in adults with schizophrenia,” the researchers wrote in their discussion of the findings.
The current study “extends our previous findings and suggests a critical role for disturbances in emerging fetal cerebral cortical folding development in mediating the association between prenatal maternal distress and neurodevelopmental problems that later manifest in infancy,” they explained.
The researchers also found that prenatal maternal anxiety, stress, and depression were positively associated with all measures of parenting stress at the 18-month testing visit.
The study findings were limited by several factors including the use of self-reports for both maternal distress and infant social-emotional assessment, despite the use of validated questionnaires, and the fact that assessment of maternal distress at specific times may not reflect the entire pregnancy, the researchers noted. Other potential limitations included the inability to use some MRI data because of fetal movement and the homogenous population of relatively highly educated women with access to health care that may not reflect other areas, they said.
“Identifying early brain developmental biomarkers may help improve the identification of infants at risk for later neurodevelopmental impairment who might benefit from early targeted interventions,” the researchers concluded.
Technology enhances health and disease models
The effect of the prenatal period on future well-being is recognized, but the current study makes “substantial contributions to prenatal programming science, with implications for ways to transform the prenatal care ecosystem for two-generation impact,” Catherine Monk, PhD, and Cristina R. Fernández, MD, both of Columbia University, New York, wrote in an accompanying editorial.
The developmental origins of health and disease (DOHaD) conceptual model introduced by Dr. David Barker in 1995 were later applied to show that maternal stress, depression, and anxiety affected child prenatal and future development, they said. However, the current study uses cutting-edge neuroscience to directly assess developing fetal brains. The finding of reduced cognitive functioning at 18 months associated with maternal stress is consistent with other findings, they noted.
“Finding an association between maternal prenatal stress and infant cognitive outcomes in the setting of what may be modest stress relative to that of a low-resourced or historically marginalized sample underscores the importance of this research; presumably, with higher stress, and greater social determinants of health burden, the effect sizes would be even greater and of greater concern,” they said.
However, studies such as the current one “have the potential to transform the prenatal and postpartum care ecosystems,” by encouraging a whole-person approach to the care of pregnant women, including attention to mental well-being and quality of life, they emphasized.
COVID-19 stress considerations
In a separate study published in Communications Medicine, Yuan-Chiao Lu, MD, also of Children’s National Hospital in Washington, and colleagues found a similar effect of maternal stress on fetal brain development.
The researchers imaged the brains of fetuses before and during the COVID-19 pandemic and interviewed mothers about any distress they experienced during pregnancy.
The study population included 65 women with known COVID-19 exposures who underwent 92 fetal MRIs and 137 prepandemic controls who underwent 182 fetal MRIs. Maternal distress was measured via the Spielberger State Anxiety Inventory, Spielberger Trait Anxiety Inventory, Perceived Stress Scale, and Edinburgh Postnatal Depression Scale.
Overall, scores on measures of stress and depression were significantly higher for women in the pandemic group compared with controls. Of the 173 women for whom maternal distress measures were available, 28% of the prepandemic group and 52% of the pandemic group met criteria for elevated maternal psychological distress, defined as above the threshold for distress on any one of the four measures.
After the researchers controlled for maternal distress, MRI data showed decreases in fetal white matter and in hippocampal and cerebellar volumes in fetuses in the pandemic group compared with controls.
Other signs of impaired brain development were similar to those seen in the JAMA Network Open study, including decreased cortical surface area and local gyrification index, as well as reduced sulcal depth in multiple brain lobes, indicating delayed cerebral cortical gyrification.
The second study was limited by a lack of data on other lifestyle changes during the pandemic that might influence maternal health and fetal development, the researchers noted. Other limitations were the possible lack of generalizability to a range of racial and ethnic populations and geographic areas outside of Washington, and the inability to control for unknown COVID-19 exposures or subclinical infections in controls, they said.
However, the results support findings from previous studies, and provide a unique opportunity to study the effect of prenatal stress on early development, as well as a chance to implement “novel and timely interventions,” the researchers wrote.
“Monitoring the COVID generation of infants for long-term cognitive and health outcomes after birth is warranted and currently underway,” and continued research may inform preventive strategies for pregnant women experiencing multiple stressors beyond the pandemic, they concluded.
Interpret pandemic effect with caution
“Research studies, as well as our own daily experiences, have made it abundantly clear that stress is on the rise as a consequence of the COVID-19 pandemic,” said editorial author Dr. Monk, who commented on the second study in an interview. “This is an important public health question: Early identification of pandemic effects on child development can help garner the necessary resources to intervene early, dramatically increasing the likelihood of improving that child’s developmental trajectory,” she said.
“The pandemic is an unprecedented experience that has widespread impact on people’s lives, how could it not also alter gestational biology and the developing brain? That being said, we need to be cautious in that we do not yet know the functional implications of these brain changes for longer-term development,” Dr. Monk said. “Also, we do not know what aspects of women’s pandemic-affected lives had an influence on fetal brain development. The authors found higher stress in pandemic versus nonpandemic women, but not evidence that distress was the mediating variable relating pregnancy during the pandemic to altered brain development,” she explained.
The take-home message for clinicians is to “provide your patients with realistic avenues for neurodevelopmental assessments of their children if they, or you, have concerns,” Dr. Monk said. “However, do not prejudge ‘pandemic babies,’ as not all children will be affected by these potential pandemic effects,” she emphasized. “It is possible to misjudge normal variation in children’s development and unnecessarily raise parents’ anxiety levels. Importantly, this period of brain plasticity means any needed intervention likely can have a big, ameliorating impact,” she added.
“We need follow-up studies looking at pandemic effects on prenatal and postnatal development and what factors protect the fetus and birthing person from the negative influences,” she said.
The JAMA study was supported by the National Institutes of Health and the A. James & Alice B. Clark Foundation. The study in Communications Medicine was supported by the National Institutes of Health, the Intellectual and Developmental Disabilities Research Center, and the A. James & Alice B. Clark Foundation. None of the researchers in either study disclosed conflicts of interest. Dr. Monk disclosed grants from the National Institutes of Health, the Bezos Family Foundation, and the Robin Hood Foundation outside the submitted work.

The mean age of the mothers was 35 years; maternal distress was assessed between 24 and 40 weeks’ gestation using validated self-report questionnaires. Parenting stress was assessed at the 18-month infant testing using the Parenting Stress Index-Short Form.
Overall, prenatal maternal stress was negatively associated with infant cognitive performance (P = .01) at 18 months, mediated by fetal left hippocampal volume.
In addition, increased fetal cortical local gyrification index and sulcal depth measured during reported times of prenatal maternal distress were associated with significantly poorer social-emotional scores and competence scores at age 18 months. The beta coefficients for local gyrification index and sulcal depth were –54.62 and –14.22, respectively, for social-emotional and competence scores, –24.01 and –7.53, respectively; P values were P < .001, P < .002, P = .003, P < .001, respectively.
“Increased cortical gyrification has been suggested in children with dyslexia and autism, and sulcal depth has been associated with the severity of impaired performance on working memory and executive function in adults with schizophrenia,” the researchers wrote in their discussion of the findings.
The current study “extends our previous findings and suggests a critical role for disturbances in emerging fetal cerebral cortical folding development in mediating the association between prenatal maternal distress and neurodevelopmental problems that later manifest in infancy,” they explained.
The researchers also found that prenatal maternal anxiety, stress, and depression were positively associated with all measures of parenting stress at the 18-month testing visit.
The study findings were limited by several factors including the use of self-reports for both maternal distress and infant social-emotional assessment, despite the use of validated questionnaires, and the fact that assessment of maternal distress at specific times may not reflect the entire pregnancy, the researchers noted. Other potential limitations included the inability to use some MRI data because of fetal movement and the homogenous population of relatively highly educated women with access to health care that may not reflect other areas, they said.
“Identifying early brain developmental biomarkers may help improve the identification of infants at risk for later neurodevelopmental impairment who might benefit from early targeted interventions,” the researchers concluded.
Technology enhances health and disease models
The effect of the prenatal period on future well-being is recognized, but the current study makes “substantial contributions to prenatal programming science, with implications for ways to transform the prenatal care ecosystem for two-generation impact,” Catherine Monk, PhD, and Cristina R. Fernández, MD, both of Columbia University, New York, wrote in an accompanying editorial.
The developmental origins of health and disease (DOHaD) conceptual model introduced by Dr. David Barker in 1995 were later applied to show that maternal stress, depression, and anxiety affected child prenatal and future development, they said. However, the current study uses cutting-edge neuroscience to directly assess developing fetal brains. The finding of reduced cognitive functioning at 18 months associated with maternal stress is consistent with other findings, they noted.
“Finding an association between maternal prenatal stress and infant cognitive outcomes in the setting of what may be modest stress relative to that of a low-resourced or historically marginalized sample underscores the importance of this research; presumably, with higher stress, and greater social determinants of health burden, the effect sizes would be even greater and of greater concern,” they said.
However, studies such as the current one “have the potential to transform the prenatal and postpartum care ecosystems,” by encouraging a whole-person approach to the care of pregnant women, including attention to mental well-being and quality of life, they emphasized.
COVID-19 stress considerations
In a separate study published in Communications Medicine, Yuan-Chiao Lu, MD, also of Children’s National Hospital in Washington, and colleagues found a similar effect of maternal stress on fetal brain development.
The researchers imaged the brains of fetuses before and during the COVID-19 pandemic and interviewed mothers about any distress they experienced during pregnancy.
The study population included 65 women with known COVID-19 exposures who underwent 92 fetal MRIs and 137 prepandemic controls who underwent 182 fetal MRIs. Maternal distress was measured via the Spielberger State Anxiety Inventory, Spielberger Trait Anxiety Inventory, Perceived Stress Scale, and Edinburgh Postnatal Depression Scale.
Overall, scores on measures of stress and depression were significantly higher for women in the pandemic group compared with controls. Of the 173 women for whom maternal distress measures were available, 28% of the prepandemic group and 52% of the pandemic group met criteria for elevated maternal psychological distress, defined as above the threshold for distress on any one of the four measures.
After the researchers controlled for maternal distress, MRI data showed decreases in fetal white matter and in hippocampal and cerebellar volumes in fetuses in the pandemic group compared with controls.
Other signs of impaired brain development were similar to those seen in the JAMA Network Open study, including decreased cortical surface area and local gyrification index, as well as reduced sulcal depth in multiple brain lobes, indicating delayed cerebral cortical gyrification.
The second study was limited by a lack of data on other lifestyle changes during the pandemic that might influence maternal health and fetal development, the researchers noted. Other limitations were the possible lack of generalizability to a range of racial and ethnic populations and geographic areas outside of Washington, and the inability to control for unknown COVID-19 exposures or subclinical infections in controls, they said.
However, the results support findings from previous studies, and provide a unique opportunity to study the effect of prenatal stress on early development, as well as a chance to implement “novel and timely interventions,” the researchers wrote.
“Monitoring the COVID generation of infants for long-term cognitive and health outcomes after birth is warranted and currently underway,” and continued research may inform preventive strategies for pregnant women experiencing multiple stressors beyond the pandemic, they concluded.
Interpret pandemic effect with caution
“Research studies, as well as our own daily experiences, have made it abundantly clear that stress is on the rise as a consequence of the COVID-19 pandemic,” said editorial author Dr. Monk, who commented on the second study in an interview. “This is an important public health question: Early identification of pandemic effects on child development can help garner the necessary resources to intervene early, dramatically increasing the likelihood of improving that child’s developmental trajectory,” she said.
“The pandemic is an unprecedented experience that has widespread impact on people’s lives, how could it not also alter gestational biology and the developing brain? That being said, we need to be cautious in that we do not yet know the functional implications of these brain changes for longer-term development,” Dr. Monk said. “Also, we do not know what aspects of women’s pandemic-affected lives had an influence on fetal brain development. The authors found higher stress in pandemic versus nonpandemic women, but not evidence that distress was the mediating variable relating pregnancy during the pandemic to altered brain development,” she explained.
The take-home message for clinicians is to “provide your patients with realistic avenues for neurodevelopmental assessments of their children if they, or you, have concerns,” Dr. Monk said. “However, do not prejudge ‘pandemic babies,’ as not all children will be affected by these potential pandemic effects,” she emphasized. “It is possible to misjudge normal variation in children’s development and unnecessarily raise parents’ anxiety levels. Importantly, this period of brain plasticity means any needed intervention likely can have a big, ameliorating impact,” she added.
“We need follow-up studies looking at pandemic effects on prenatal and postnatal development and what factors protect the fetus and birthing person from the negative influences,” she said.

Babies of mothers who experience significant psychological distress during pregnancy showed evidence of altered brain development in utero and reduced cognitive outcomes at 18 months, based on data from a pair of studies including approximately 300 women.
In a longitudinal study published in JAMA Network Open, Yao Wu, PhD, of Children’s National Hospital, Washington, and colleagues recruited 97 healthy mother-infant dyads between January 2016 and October 2020 at a single center. Of these, 87 underwent two fetal brain imaging studies each, and 10 completed the first MRI visit, for a total of 184 fetal MRIs.

Parents fall short on infant sleep safety
Less than 10% of parents followed recommended safe sleep practices for their infants aged 12 months and younger at both sleep onset and after nighttime waking, based on data from a survey of 1,500 parents published in Pediatrics.
Sleep-related death remains a major cause of infant mortality in the United States despite the early success of public health campaigns for safe sleep practices, such as “Back to Sleep,” and many parents persist in unsafe practices such as prone positioning and bed-sharing, Mersine A. Bryan, MD, of the University of Washington, Seattle, and colleagues wrote. “Though nighttime waking is common for infants, less attention has been paid to the safety of second-sleep practices.”
To examine the prevalence and safety of infant second-sleep practices, the researchers used a cross-sectional online survey to collect information on sleep practices from parents of infants aged 12 months and younger; 74% of the respondents were female, 65% were White, 12% were Black, and 17% were Hispanic. The mean age of the infants was 6.6 months, and 24% were aged 3 months and younger.
The survey included parent reports of three safe sleep practices based on the American Academy of Pediatrics 2016 Safe Infant Sleep Guidelines: supine infant sleep position, use of a separate sleep space (vs. bed sharing), and use of an approved surface/safe location (such as a bassinet, crib, cradle, or play yard vs. an adult bed).
Parents were asked to report sleep practices at sleep onset and at nighttime waking, and the researchers used a composite score to determine safe practices were met at each of these two time points.
Of the 1,500 participants, 581 (39%), reported any second-sleep practice. Of the 482 who reported on all three sleep practices at both time points, 29% met all three safe sleep criteria at sleep onset and 9% met all three safe sleep criteria at sleep onset and nighttime waking.
Of the parents who reported second sleep practices, 39% reported changes in practice after nighttime waking from sleep onset. Significantly more parents who switched practices between sleep onset and nighttime waking shifted from a safer to a less safe practice, the researchers noted.
For positioning, 67% of respondents overall reported placing infants on their backs at sleep onset. Among the 564 who reported a second sleep position, 42% placed infants on their backs again; 13% switched from supine to nonsupine positions and 7% changed from nonsupine to supine.
For sleep spaces, 72% of participants overall reported a separate sleep space for infants at sleep onset. Of the 508 who reported on second-sleep spaces, 54% kept infants in a separate space after nighttime waking, 18% shifted to a shared space after nighttime waking. Of those in shared spaces at sleep onset, 8% shifted to separate spaces after nighttime waking.
For sleep location, 71% of respondents overall used an approved sleep surface at sleep onset. Of the 560 who reported sleep location at both time points, 42% remained in a safe location after nighttime waking, while 30% were moved from a safe to an unsafe location, and 10% of those in an unsafe location were moved from an unsafe to a safe location.
In a multivariate analysis, the researchers examined the demographics associated with changes in sleep practice after nighttime waking. Parents younger than 25 years, first-time parents, those who identified as Black non-Hispanic or Hispanic, smokers, and those with preterm infants (less than 37 weeks’ gestation) were more likely to change sleep practices after nighttime waking. However, parents who reported a safe sleep practice at sleep onset were more likely to do so after nighttime waking.
“We hypothesize that expansion of existing strategies to promote infant safe sleep practices to include sleep practices after nighttime waking can have a positive impact on infant safe sleep,” the researchers wrote.
The study findings were limited by several factors including the use of an online survey, which limited the study population to those with internet and computer access, and the reliance on self-reports and only two time points, the researchers noted. Other limitations included the inclusion of only three of the AAP sleep recommendations, and the inclusion of only English speakers.
However, the results were strengthened by the large, diverse, and geographically representative sample of parents.
“When advising families about infant sleep, pediatricians should discuss nighttime wakings with parents because they are common and reinforce the need for safe sleep practices every time,” the researchers noted.
Increase opportunities for education
The current study is important because infants continue to die or experience life-long catastrophic health outcomes as a result of not following safe sleep practices, Cathy Haut, DNP, CPNP-AC, CPNP-PC, a pediatric nurse practitioner in Rehoboth Beach, Del., said in an interview.
“I am not surprised by the study findings,” said Dr. Haut, who was not involved in the study. “As a pediatric nurse practitioner for over 35 years, I see infant sleep as a continuing challenge for families. In today’s fast-paced world, multiple priorities leave parents few resources for managing their own well-being, with adequate sleep being one health requirement that is often not met for them.”
To improve safe sleep practices, “it is imperative for health care providers in any setting to address safe sleep practices for infants and children,” said Dr. Haut. “In addition to safety, opportunity for adequate hours of sleep is also important.” She acknowledged that, “in the office setting, time is a huge barrier to completing comprehensive anticipatory guidance. When parents ask questions about sleep, they are often doing everything they can to physically make it through the night with a crying infant. Enforcing safe practices at this point is extremely difficult.”
However, some opportunities for safe sleep education include the prenatal period when parents can take time to listen and plan, not just for feeding preferences but for safe infant sleep practices, Dr. Haut noted.
“When sleep is a problem, families can be invited back to the office for additional counseling and education, which allows more time than within a scheduled health visit,” Dr. Haut emphasized. “Finally, enhanced public awareness is an aspect of learning. In my career I have seen the devastating results of suffocation while cosleeping as well as injuries from falling from a bed or inappropriate sleeping space, and other poor outcomes from inadequate support for safe sleep habits.”
As for additional research, studies are needed to include larger populations and “to further quantify positive outcomes of following safe sleeping practices,” said Dr. Haut. The results of these studies should be made available to the general public, not only to health care professionals.
The study was supported by Seattle Children’s Research Institute. The researchers had no financial conflicts to disclose. Dr. Haut had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.

“When sleep is a problem, families can be invited back to the office for additional counseling and education, which allows more time than within a scheduled health visit,” Dr. Haut emphasized. “Finally, enhanced public awareness is an aspect of learning. In my career I have seen the devastating results of suffocation while cosleeping as well as injuries from falling from a bed or inappropriate sleeping space, and other poor outcomes from inadequate support for safe sleep habits.”
As for additional research, studies are needed to include larger populations and “to further quantify positive outcomes of following safe sleeping practices,” said Dr. Haut. The results of these studies should be made available to the general public, not only to health care professionals.
The study was supported by Seattle Children’s Research Institute. The researchers had no financial conflicts to disclose. Dr. Haut had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.

Phase-3 study: Leukemia patients live longer with ibrutinib
“This trial led to the first-line approval of ibrutinib for CLL patients,” lead author Paul M. Barr, MD, of the University of Rochester (N.Y.), said in an interview. “It is important to follow these patients long-term to understand the expected duration of response/disease control and to monitor for late toxicity,” he said “The data are useful in guiding clinicians who treat CLL and patients being treated with single agent BTK inhibitors,” he noted.
In the initial RESONATE-2, a phase 3, open-label study, 269 adults aged 65 years and older who were previously untreated for CLL or small lymphocytic leukemia were randomized to ibrutinib or the standard of care, chlorambucil. Patients received 420 mg of ibrutinib once daily until disease progression or unacceptable toxicity (136 patients) or up to 12 cycles of 0.5-0.8 mg/kg of chlorambucil (133 patients).
The long-term outcome data were published in Blood Advances.
Overall, at a median of 83 months’ follow-up, progression-free survival was significantly higher for ibrutinib patients than for chlorambucil patients (hazard ratio 0.154).
At 7 years, progression-free survival was 59% in the ibrutinib group vs. 9% in the chlorambucil group.
Notably, progression-free survival benefits with ibrutinib also were higher for patients with high-risk genomic features, identified as del(11q) and unmutated immunoglobulin heavy-chain variable region gene (IGHV).
Complete data were available for 54 patients with del(11q) and 118 with unmutated IGHV. In this subset of patients, progression-free survival rates at 7 years were significantly higher for those treated with ibrutinib vs. chlorambucil who had del(11q) or unmutated IGHV (52% vs. 0% and 58% vs. 2%, respectively).
Approximately 42% of patients with chronic lymphocytic leukemia treated with ibrutinib remained on the therapy at up to 8 years, with a median follow-up of 7.4 years. Overall survival at 7 years was 78% for ibrutinib; overall survival data were not collected for chlorambucil for patients with progressive disease after the median of 5 years, as these patients were eligible to switch to ibrutinib in a long-term extension study or exit the study.
Adverse events prompted reduction of ibrutinib in 30 patients and dose holding for at least 7 days in 79 patients. However, dose modification resolved or improved the adverse events in 85% of the patients with held doses and 90% of those with reduced doses.
The overall prevalence of adverse events was similar to previous follow-up data at 5 years. No new safety signals were observed during the longer study period. The rate of treatment discontinuation because of adverse events was highest in the first year.
“We have been surprised at how long the remissions have lasted with ibrutinib,” said Dr. Barr. “Even with up to 8 years of follow-up, we have yet to reach the median progression free-survival,” he noted.
“These data, in combination with other data sets, highlight the impact that ibrutinib and other BTK inhibitors have had in treating CLL,” said Dr. Barr. “Patients are living longer and avoiding the side effects of chemotherapy in the era of novel agent use,” he said.
However, research gaps remain, Dr. Barr noted. “We need to continue following these patients over time given the length of the remissions. Additionally, we need to continue investigating novel combinations,” he said. Such studies will help us understand the benefit of fixed durations regimens compared to single agent BTK inhibitors,” he emphasized.
Safety and efficacy remain promising
“Ibrutinib was approved for the treatment of CLL, but only in the relapsed setting,” Susan M. O’Brien, MD, of the University of California, Irvine, said in an interview. “This trial was important because it led to the approval of ibrutinib in the front-line setting, making it the first, and at the time, only, small molecule that could be used upfront,” said Dr. O’Brien, who was not involved with the study.
“The initial results were certainly not surprising, as given the efficacy of ibrutinib in the relapsed setting, it seemed likely that it would produce a longer PFS than chlorambucil,” said Dr. O’Brien. “What may not have been expected though, is the incredible durability of these responses with ibrutinib,” she noted.
The clinical implications of the long-term data are that ibrutinib is producing “very durable remissions with continuous therapy,” Dr. O’Brien said. “There are no late safety signals and most side effects diminish with time. However, hypertension and atrial fibrillation continue to occur, so continued monitoring of blood pressure in these patients is important,” she emphasized.
Minor, but annoying, side effects are not infrequent early on with ibrutinib and may present a barrier to use for some patients, Dr. O’Brien said. “Some side effects may be overcome with temporary pauses of drug or dose reduction,” she noted. However, “it is important for patients to be aware that most of these side effects will completely abate with time,” she added.
“The main limitation of this trial was that the comparison was to a rather weak chemotherapy agent, albeit it one frequently used in older patients, particularly in Europe,” said Dr. O’Brien. “Nevertheless, two subsequent trials comparing ibrutinib (with or without rituximab) with either BR [bendamustine/rituximab] or FCR [fludarabine/cyclophosphamide/rituximab] showed a longer PFS with ibrutinib, as compared to that seen with either chemoimmunotherapy regimen,” she said.
The study was supported by Pharmacyclics LLC, an AbbVie company. Dr. Barr collaborated with sponsor AbbVie on the study design, and disclosed relationships with companies including AbbVie, AstraZeneca, Bristol Myers Squibb, Celgene, Genentech, Gilead, Janssen, MEI Pharma, Merck, Morphosys, Pharmacyclics LLC (an AbbVie company), Seattle Genetics, and TG Therapeutics.

FDA approves topical tapinarof for plaque psoriasis
The the manufacturer announced.
Tapinarof is an aryl hydrocarbon receptor agonist and is the first FDA-approved steroid-free topical medication in this class, according to a press release from the manufacturer, Dermavant.
Approval was based on results of three studies in a phase 3 clinical trial program (PSOARING 1, PSOARING 2), and an open-label extension study, (PSOARING 3), the company release said. In PSOARING 1 and 2, approximately 1,000 adults aged 18-75 years (median age, 51 years) with plaque psoriasis were randomized to once-daily topical tapinarof or placebo for up to 12 weeks; 85% were White and 57% were men. The study findings were published in the New England Journal of Medicine in December 2021.
The primary endpoint for both trials was the proportion of patients who achieved Physician Global Assessment (PGA) scores score of “clear” (0) or “almost clear” (1) and improvement of at least two grades from baseline.
After 12 weeks, 36% of the patients in PSOARING 1 and 40% in PSOARING 2 who received tapinarof met the primary outcome, compared with 6% of patients on placebo (P < .001 for both studies). Of these, a total of 73 patients from both studies who achieved PGA scores of 0 were entered in PSOARING 3, a 40-week open-label extension study, in which they stopped tapinarof treatment and retained PGA scores of 0 or 1 for approximately 4 months off treatment. An additional 312 patients who were enrolled in the PSOARING 3 extension study achieved PGA scores of 0 at least once during the study period, with “remittive” effects lasting a mean of 130 days off of treatment.
In addition, patients who received tapinarof in the PSOARING 1 and 2 studies showed significant improvement from baseline, compared with patients on placebo, across a range of secondary endpoints including a 75% or greater improvement in Psoriasis Area and Severity Index score (PASI 75).
In PSOARING 1, and 2, respectively, 36.1% and 47.6% of those on tapinarof achieved a PASI 75 response at week 12, compared with 10.2% and 6.9% of those on the vehicle (P < .001 for both).
Across all three studies, the majority adverse events were mild to moderate, and limited to the application site.
The most common adverse events reported by patients in the tapinarof groups were folliculitis, nasopharyngitis, and contact dermatitis. Headaches were more common among those treated with tapinarof than those on vehicle in the studies (3.8% vs. 2.4% in PSOARING 1, and 3.8% vs. 0.6% in PSOARING 2), leading to only three treatment discontinuations.
At the end of the PSOARING 3 study (at either week 40 or early termination), 599 participants responded to satisfaction questionnaires. Of these, 83.6% said they were satisfied with the results of tapinarof treatment, and 81.7% said it was more effective than previous topical treatments they had used, according to the company’s release.
Tapinarof cream can be used on all areas of the body, including the face, skin folds, neck, genitalia, anal crux, inflammatory areas, and axillae, according to the company release.

Contraceptive use boosted by enhanced counseling
Contraceptive counseling and interventions beyond usual care significantly increased the use of contraceptives with no accompanying increase in sexually transmitted infections or reduction in condom use, based on data from a new meta-analysis.
“Although effective contraception is available in the United States and guidelines support contraceptive care in clinical practice, providing contraceptive care has not been widely adopted across medical specialties as a preventive health service that is routinely offered to eligible patients, such as mammography screening,” lead author Heidi D. Nelson, MD, of Kaiser Permanente Bernard J. Tyson School of Medicine, Pasadena, Calif., said in an interview.
“Access to and coverage of contraceptive care are frequently challenged by legislation and insurance policies, and influential preventive services guideline groups, such as the U.S. Preventive Services Task Force, have not issued recommendations for contraceptive care,” Dr. Nelson said.
“The evidence to determine the benefits and harms of contraceptive care as a preventive health service has not been examined using methods similar to those used for other preventive services and clinicians may lack guidance on the effectiveness of contraception services relevant to their practices,” she added.
In a study published in Annals of Internal Medicine, Dr. Nelson and colleagues reviewed data from 38 randomized, controlled trials with a total of 25,472 participants. The trials evaluated the effectiveness of various types of contraceptive counseling and provision interventions beyond usual care on subsequent contraception use, compared with nonintervention comparison groups.
Overall, higher contraceptive use was associated with counseling interventions (risk ratio, 1.39), advance provision of emergency contraception (RR, 2.12), counseling or provision of emergency contraception postpartum (RR, 1.15), or counseling or provision of emergency contraception at the time of abortion (RR, 1.19), compared with usual care or active controls across studies.
Most of the included trials were not powered to distinguish intended versus unintended pregnancy rates, but pregnancy rates were lower among intervention groups, compared with controls.
Five of the selected studies assessed the potential negative effect of contraceptive counseling with regard to increased rates of STIs and two studies examined decreased condom use. However, neither STI rates nor condom use were significantly different between study participants who received various contraceptive counseling interventions (such as advanced provision of emergency contraception, clinician training, and individual counseling) and those who did not (RR, 1.05 and RR, 1.03, respectively).
“These results indicate that additional efforts to assist patients with their contraception decisions improve its subsequent use,” and are not surprising, said Dr. Nelson.
“All clinicians providing health care to women, not only clinicians providing reproductive health care specifically, need to recognize contraceptive care as an essential preventive health service and assume responsibility for delivering contraceptive counseling and provision services appropriate for each patient,” Dr. Nelson emphasized. “Clinicians lacking contraceptive care clinical skills may require additional training or refer their patients if needed to assure high quality care.”
The study findings were limited by several factors including the variability of interventions across studies and the lack of data on unintended pregnancy outcomes, the researchers noted. However, the results suggest that various contraceptive counseling and interventions beyond usual care increased contraceptive use with no reduction in condom use or increase in STIs, they wrote.
“Additional research should further evaluate approaches to contraceptive counseling and provision to determine best practices,” Dr. Nelson said in an interview. “This is particularly important for medically high-risk populations, those with limited access to care, and additional populations and settings that have not yet been studied, including transgender and nonbinary patients. Research is needed to refine measures of pregnancy intention and planning; and create uniform definitions of contraceptive care, interventions, measures of use, and outcomes.”.
Make easy, effective contraception accessible to all
The news of a potential overturn of the 1973 Roe v. Wade Supreme Court decision that protects a pregnant person’s ability to choose abortion “shines a bright light on the importance of promoting the use of contraception,” and on the findings of the current review, Christine Laine, MD, editor-in-chief of Annals of Internal Medicine, wrote in an accompanying editorial. “Easy, effective, accessible, and affordable contraception becomes increasingly essential as ending unintended pregnancy becomes increasingly difficult, unsafe, inaccessible, and legally risky.”
The available evidence showed the benefits of enhanced counseling, providing emergency contraception in advance, and providing contraceptive interventions immediately after delivery or pregnancy termination, she wrote. The findings have strong clinical implications, especially with regard to the Healthy People 2030 goal of reducing unintended pregnancy from the current 43% to 36.5%.
Dr. Laine called on internal medicine physicians in particular to recognize the negative health consequences of unintended pregnancy, and to consider contraceptive counseling part of their responsibility to their patients.
“To expand the numbers of people who receive this essential preventive service, we must systematically incorporate contraceptive counseling into health care with the same fervor that we devote to other preventive services. The health of our patients – and their families – depends on it,” she concluded.

“Although effective contraception is available in the United States and guidelines support contraceptive care in clinical practice, providing contraceptive care has not been widely adopted across medical specialties as a preventive health service that is routinely offered to eligible patients, such as mammography screening,” lead author Heidi D. Nelson, MD, of Kaiser Permanente Bernard J. Tyson School of Medicine, Pasadena, Calif., said in an interview.
“Access to and coverage of contraceptive care are frequently challenged by legislation and insurance policies, and influential preventive services guideline groups, such as the U.S. Preventive Services Task Force, have not issued recommendations for contraceptive care,” Dr. Nelson said.
“The evidence to determine the benefits and harms of contraceptive care as a preventive health service has not been examined using methods similar to those used for other preventive services and clinicians may lack guidance on the effectiveness of contraception services relevant to their practices,” she added.
In a study published in Annals of Internal Medicine, Dr. Nelson and colleagues reviewed data from 38 randomized, controlled trials with a total of 25,472 participants. The trials evaluated the effectiveness of various types of contraceptive counseling and provision interventions beyond usual care on subsequent contraception use, compared with nonintervention comparison groups.
Overall, higher contraceptive use was associated with counseling interventions (risk ratio, 1.39), advance provision of emergency contraception (RR, 2.12), counseling or provision of emergency contraception postpartum (RR, 1.15), or counseling or provision of emergency contraception at the time of abortion (RR, 1.19), compared with usual care or active controls across studies.
Most of the included trials were not powered to distinguish intended versus unintended pregnancy rates, but pregnancy rates were lower among intervention groups, compared with controls.
Five of the selected studies assessed the potential negative effect of contraceptive counseling with regard to increased rates of STIs and two studies examined decreased condom use. However, neither STI rates nor condom use were significantly different between study participants who received various contraceptive counseling interventions (such as advanced provision of emergency contraception, clinician training, and individual counseling) and those who did not (RR, 1.05 and RR, 1.03, respectively).
“These results indicate that additional efforts to assist patients with their contraception decisions improve its subsequent use,” and are not surprising, said Dr. Nelson.
“All clinicians providing health care to women, not only clinicians providing reproductive health care specifically, need to recognize contraceptive care as an essential preventive health service and assume responsibility for delivering contraceptive counseling and provision services appropriate for each patient,” Dr. Nelson emphasized. “Clinicians lacking contraceptive care clinical skills may require additional training or refer their patients if needed to assure high quality care.”
The study findings were limited by several factors including the variability of interventions across studies and the lack of data on unintended pregnancy outcomes, the researchers noted. However, the results suggest that various contraceptive counseling and interventions beyond usual care increased contraceptive use with no reduction in condom use or increase in STIs, they wrote.
“Additional research should further evaluate approaches to contraceptive counseling and provision to determine best practices,” Dr. Nelson said in an interview. “This is particularly important for medically high-risk populations, those with limited access to care, and additional populations and settings that have not yet been studied, including transgender and nonbinary patients. Research is needed to refine measures of pregnancy intention and planning; and create uniform definitions of contraceptive care, interventions, measures of use, and outcomes.”.
Make easy, effective contraception accessible to all
The news of a potential overturn of the 1973 Roe v. Wade Supreme Court decision that protects a pregnant person’s ability to choose abortion “shines a bright light on the importance of promoting the use of contraception,” and on the findings of the current review, Christine Laine, MD, editor-in-chief of Annals of Internal Medicine, wrote in an accompanying editorial. “Easy, effective, accessible, and affordable contraception becomes increasingly essential as ending unintended pregnancy becomes increasingly difficult, unsafe, inaccessible, and legally risky.”
The available evidence showed the benefits of enhanced counseling, providing emergency contraception in advance, and providing contraceptive interventions immediately after delivery or pregnancy termination, she wrote. The findings have strong clinical implications, especially with regard to the Healthy People 2030 goal of reducing unintended pregnancy from the current 43% to 36.5%.
Dr. Laine called on internal medicine physicians in particular to recognize the negative health consequences of unintended pregnancy, and to consider contraceptive counseling part of their responsibility to their patients.
“To expand the numbers of people who receive this essential preventive service, we must systematically incorporate contraceptive counseling into health care with the same fervor that we devote to other preventive services. The health of our patients – and their families – depends on it,” she concluded.

Cannabis vaping continues its rise in teens
More teenagers in the United States reported cannabis use with vaping in 2019, compared with 2017, while cannabis use without vaping declined, based on annual survey data from more than 50,000 teens.
“With vaping prevalence rising so quickly among teens, getting a clearer picture of how cannabis use is shifting helps inform prevention and cessation efforts,” corresponding author Noah T. Kreski, MPH, of Columbia University, New York, said in an interview.
“In just 2 years, the most common cannabis use pattern changed from ‘occasional use without vaping’ to ‘frequent use with vaping,’ said Mx. Kreski, who uses the honorific Mx. and the pronouns they/them. “Knowing that, as well as the high overlap of cannabis vaping with nicotine use and binge drinking, adds to the urgency of reducing adolescent vaping.”
To quantify the trends in cannabis vaping, the researchers reviewed data from Monitoring the Future, an annual survey of high school students across the United States. The study population included 51,052 individuals; approximately 49% were male and 49% were non-Hispanic White. The researchers examined frequency of cannabis use, trends across demographic groups, and concurrent use of cannabis and other substances such as alcohol and tobacco. The findings were published in the journal Addiction.
Frequent cannabis use was defined as six or more times in the past 30 days; occasional use was defined as one to five times in the past 30 days.
Frequent cannabis use with vaping increased from 2.1% in 2017 to 5.4% in 2019. Occasional cannabis use with vaping also increased, though less dramatically, from less than 2% in 2017 to approximately 3.5% in 2019.
By contrast, both frequent and occasional cannabis use without vaping declined from 2017 to 2019 (from 3.8% to 2.1% and from 6.9% to 4.4%, respectively).
Overall, the prevalence of any level of cannabis use increased from 13.9% in 2017 to 15.4% in 2019. Both males and females showed a similar increase in reported frequent cannabis use with vaping of approximately 3%.
The results document that vaping cannabis has become more common than smoking alone among U.S. teens across almost all demographic groups, and across sex, race, urbanicity, and level of parent education; however, the increased was especially marked among Hispanic/Latinx teens and those of lower socioeconomic status, the researchers wrote.
The researchers also examined the associations between cannabis use with and without vaping and concurrent nicotine and alcohol use. Overall, the strongest association was between smoking or vaping nicotine and vaping cannabis; teens who smoked or vaped nicotine were 42 times more likely than nonnicotine users to report vaping cannabis in the past 30 days (adjusted odds ratio, 42.28). In addition, more occasions of binge drinking were more strongly associated with cannabis use with vaping (up to 10 times more likely), compared with cannabis use without vaping, (aORs, 4.48-10.09).
The study findings were limited by several factors, including the lack of questions on tetrahydrocannabinol (THC) or cannabidiol content of the cannabis products used, although evidence suggests that the potency of cannabis products in the United States is increasing, the researchers noted. Other limitations included the cross-sectional design, which prevents making associations about causality, and lack of data on the quantity of cannabis used; only data on frequency of use were recorded.
However, the results reflect a rise in cannabis use with vaping among teens in the United States, along with an increased risk of tobacco use, e-cigarette use, and binge drinking, the researchers said.
As cannabis legalization expands across the United States, policies are needed to deter use among adolescents, the researchers wrote. “These policies should be crafted to reduce an emphasis on criminalization in preference for public health promotion given the history of unequal application of punitive consequences of drug use for racialized minorities in the United States. As products, delivery systems, potency, and marketing proliferate within a for-profit industry, increased attention to youth trends, including investment in sustained and evidence-based prevention and intervention, is increasingly necessary.”
The take-home message for clinicians is to ask whether your patients are vaping, because the prevalence is not only up, but fairly universal, Mx. Kreski said. “Have a discussion that covers a broad range of substance use topics and informs teens of the potential risks of vaping, while avoiding stigma.”
The message for parents is “to talk to your kids about the risks of vaping,” said Mx. Kreski. “Prioritize open communication rather than punishment, and work together with your teens to prevent or reduce vaping.” The message for teens: “Understand that vaping has risks. You should feel empowered to talk to your parents or doctor about those risks. While it may seem like everyone’s vaping, the majority don’t. Keeping communication open between parents/caregivers, teens, and health care providers is one of the best ways to address these trends in vaping.”
Beware more powerful cannabis products
“While drug use in general is declining in adolescents, marijuana use remains very common,” Kelly A. Curran, MD, of the University of Oklahoma Health Sciences Center, Oklahoma City, said in an interview.
“There is growing evidence that marijuana is now the first drug used by adolescents – replacing alcohol and nicotine – and frequent use can lead to substance abuse,” said Dr. Curran, who specializes in adolescent medicine but was involved in the study. “Cannabis use patterns have evolved over time. As I frequently tell my patients and their families, new strains and hybrids of marijuana have higher potencies of THC. Many adolescents are eschewing smoking and in its place using marijuana concentrates (wax, oil, shatter) via vape, dab pen, or rig. Use of these methods puts adolescents at high risk of social and health complications such as [e-cigarette or vaping use-associated lung injury], cannabis hyperemesis syndrome, and psychosis – and understanding these patterns and associated drug use helps health care professionals and parents keep adolescents safe.”
The take-home message for clinicians is that marijuana use via vaping continues to rise and to become more common than “traditional” marijuana smoking, Dr. Curran said. “This increase is across genders, in nearly all race/ethnicities (especially in Latinx youth), and in youth from lower socioeconomic status.” Vaping marijuana is associated with other substance abuse, so health care professionals should include questions about different forms of marijuana use, such as vape, dab pen, or rig, when working with patients, and counsel patients and families about the risks associated with use of any of these products.

Ondansetron use for acute gastroenteritis in children accelerates
Use of oral ondansetron for acute gastroenteritis in children in an emergency setting increased significantly between 2006 and 2018, but use of intravenous fluids remained consistent, based on data from a cross-sectional analysis.
Recommendations for managing acute gastroenteritis in children include oral rehydration therapy for mild to moderate cases and intravenous rehydration for severe cases, Brett Burstein, MDCM, of McGill University, Montreal, and colleagues wrote.
Oral ondansetron has been shown to reduce vomiting and the need for intravenous rehydration, as well as reduce the need for hospitalization in children with evidence of dehydration, but has no significant benefits for children who are not dehydrated, the researchers noted.
“Given the high prevalence and costs associated with acute gastroenteritis treatment for children, understanding national trends in management in a broad, generalizable sample is important,” they wrote.
In a study published in JAMA Network Open, the researchers identified data from the National Hospital Ambulatory Medical Care Survey from Jan. 1, 2006, to Dec. 31, 2018. They analyzed ED visits by individuals younger than 18 years with either a primary discharge diagnosis of acute gastroenteritis or a primary diagnosis of nausea, vomiting, diarrhea, or dehydration with a secondary diagnosis of acute gastroenteritis. The study population included 4,122 patients with a mean age of 4.8 years. Approximately 85% of the visits were to nonacademic EDs, and 80% were to nonpediatric EDs.
Overall, ED visits for acute gastroenteritis increased over time, from 1.23 million in 2006 to 1.87 million in 2018 (P = .03 for trend). ED visits for acute gastroenteritis also increased significantly as a proportion of all ED pediatric visits, from 4.7% in 2006 to 5.6% in 2018 (P = .02 for trend).
Notably, the use of ondansetron increased from 10.6% in 2006 to 59.2% in 2018; however, intravenous rehydration and hospitalizations remained consistent over the study period, the researchers wrote. Approximately half of children who received intravenous fluids (53.9%) and those hospitalized (49.1%) also received ondansetron.
“Approximately half of children administered intravenous fluids or hospitalized did not receive ondansetron, suggesting that many children without dehydration receive ondansetron with limited benefit, whereas those most likely to benefit receive intravenous fluids without an adequate trial of ondansetron and oral rehydration therapy,” the researchers wrote in their discussion of the findings.
The study findings were limited by several factors including the lack of data on detailed patient-level information such as severity of dehydration, the researchers noted. Other limitations include lack of data on return visits and lack of data on the route of medication administration, which means that the perceived lack of benefit from ondansetron may be the result of children treated with both intravenous ondansetron and fluids, they said.
“Ondansetron-supported oral rehydration therapy for appropriately selected children can achieve intravenous rehydration rates of 9%, more than threefold lower than 2018 national estimates,” and more initiatives are needed to optimize ondansetron and reduce the excessive use of intravenous fluids, the researchers concluded.
Emergency care setting may promote IV fluid use
“Acute gastroenteritis has remained a major cause of pediatric morbidity and mortality worldwide with significant costs for the health care system,” Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice who was not involved in the current study, said in an interview. “The authors highlight that although ondansetron use for acute gastroenteritis in the ED has increased substantially, there are still a number of children who receive intravenous fluids in the ED without a trial of ondansetron and [oral rehydration therapy] first. For the individual patient, it is not surprising that the fast-paced culture of the ED doesn’t cater to a watchful waiting approach. This highlights the need for a more protocol-based algorithm for care of these patients upon check-in.
“Often the practice in the ED is a single dose of ondansetron, followed by attempts at oral rehydration 30 minutes later,” said Dr. Joos. “It would be interesting to know the extent that outpatient clinics are practicing this model prior to sending the patient on to the ED. Despite it becoming a common practice, there is still ongoing research into the efficacy and safety of multidose oral ondansetron at home in reducing ED visits/hospitalizations.”
The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Joos had no financial conflicts to disclose. Lead author Dr. Burstein received a career award from the Quebec Health Research Fund.

They analyzed ED visits by individuals younger than 18 years with either a primary discharge diagnosis of acute gastroenteritis or a primary diagnosis of nausea, vomiting, diarrhea, or dehydration with a secondary diagnosis of acute gastroenteritis. The study population included 4,122 patients with a mean age of 4.8 years. Approximately 85% of the visits were to nonacademic EDs, and 80% were to nonpediatric EDs.
Overall, ED visits for acute gastroenteritis increased over time, from 1.23 million in 2006 to 1.87 million in 2018 (P = .03 for trend). ED visits for acute gastroenteritis also increased significantly as a proportion of all ED pediatric visits, from 4.7% in 2006 to 5.6% in 2018 (P = .02 for trend).
Notably, the use of ondansetron increased from 10.6% in 2006 to 59.2% in 2018; however, intravenous rehydration and hospitalizations remained consistent over the study period, the researchers wrote. Approximately half of children who received intravenous fluids (53.9%) and those hospitalized (49.1%) also received ondansetron.
“Approximately half of children administered intravenous fluids or hospitalized did not receive ondansetron, suggesting that many children without dehydration receive ondansetron with limited benefit, whereas those most likely to benefit receive intravenous fluids without an adequate trial of ondansetron and oral rehydration therapy,” the researchers wrote in their discussion of the findings.
The study findings were limited by several factors including the lack of data on detailed patient-level information such as severity of dehydration, the researchers noted. Other limitations include lack of data on return visits and lack of data on the route of medication administration, which means that the perceived lack of benefit from ondansetron may be the result of children treated with both intravenous ondansetron and fluids, they said.
“Ondansetron-supported oral rehydration therapy for appropriately selected children can achieve intravenous rehydration rates of 9%, more than threefold lower than 2018 national estimates,” and more initiatives are needed to optimize ondansetron and reduce the excessive use of intravenous fluids, the researchers concluded.
Emergency care setting may promote IV fluid use
“Acute gastroenteritis has remained a major cause of pediatric morbidity and mortality worldwide with significant costs for the health care system,” Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice who was not involved in the current study, said in an interview. “The authors highlight that although ondansetron use for acute gastroenteritis in the ED has increased substantially, there are still a number of children who receive intravenous fluids in the ED without a trial of ondansetron and [oral rehydration therapy] first. For the individual patient, it is not surprising that the fast-paced culture of the ED doesn’t cater to a watchful waiting approach. This highlights the need for a more protocol-based algorithm for care of these patients upon check-in.
“Often the practice in the ED is a single dose of ondansetron, followed by attempts at oral rehydration 30 minutes later,” said Dr. Joos. “It would be interesting to know the extent that outpatient clinics are practicing this model prior to sending the patient on to the ED. Despite it becoming a common practice, there is still ongoing research into the efficacy and safety of multidose oral ondansetron at home in reducing ED visits/hospitalizations.”
The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Joos had no financial conflicts to disclose. Lead author Dr. Burstein received a career award from the Quebec Health Research Fund.
Use of oral ondansetron for acute gastroenteritis in children in an emergency setting increased significantly between 2006 and 2018, but use of intravenous fluids remained consistent, based on data from a cross-sectional analysis.
Recommendations for managing acute gastroenteritis in children include oral rehydration therapy for mild to moderate cases and intravenous rehydration for severe cases, Brett Burstein, MDCM, of McGill University, Montreal, and colleagues wrote.
Oral ondansetron has been shown to reduce vomiting and the need for intravenous rehydration, as well as reduce the need for hospitalization in children with evidence of dehydration, but has no significant benefits for children who are not dehydrated, the researchers noted.
