Conference Coverage

Vaccination against human papillomavirus (HPV) is an effective way to prevent HPV infection and cancers typically caused by HPV, including cervical cancer and head and neck cancers, new research showed.

The analysis, featured at a press briefing ahead of the presentation at the American Society of Clinical Oncology (ASCO) 2024 annual meeting, notably found that men who received the HPV vaccine had a 56% lower risk for head and neck cancers.

“We’ve known for a long time that having the HPV vaccine can prevent the development of HPV infection, yes, but importantly, cancer,” primarily cervical cancer, said briefing moderator and ASCO president Lynn Schuchter, MD, Abramson Cancer Center, University of Pennsylvania, Philadelphia. “This is a really important study that extends the information about the impact.”

Using the US TriNetX database, lead investigator Jefferson DeKloe, BS, a research fellow with Thomas Jefferson University, Philadelphia, and colleagues created a matched cohort of 760,540 HPV-vaccinated and unvaccinated men and 945,999 HPV-vaccinated and unvaccinated women.

HPV-vaccinated men had a 54% lower risk for all HPV-related cancers (odds ratio [OR], 0.46; P < .001) and a 56% lower risk for head and neck cancers (OR, 0.44; P < .001) than unvaccinated men. There were not enough cases of anal and penile cancers for analysis.

HPV-vaccinated women had a 27% lower risk for all HPV-related cancers (OR, 0.73; P < .05), a 54% lower risk for cervical cancer (OR, 0.46; P < .05), and a 33% lower risk for head and neck cancers (OR, 0.67; 95% CI, 0.42-1.08) than HPV-unvaccinated women, but this finding was not significant. There were not enough cases of anal cancers for analysis, and the odds of developing vulvar or vaginal cancer was not significantly different in HPV-vaccinated vs unvaccinated women.

Vaccinated women, however, were less likely than unvaccinated women to develop high-grade squamous intraepithelial lesions (OR, 0.44), cervical carcinoma in situ (OR, 0.42), or abnormal Pap findings (OR, 0.87), and were less likely to undergo cone biopsy and loop electrosurgical excision (OR, 0.45).

“This study really highlights the importance of getting the HPV vaccine,” Dr. Schuchter said at the briefing.

“HPV vaccination is cancer prevention,” Glenn Hanna, MD, with Dana-Farber Cancer Institute, Boston, said in an ASCO statement.

Still, HPV vaccination rates in the United States remain relatively low. According to the National Cancer Institute, in 2022, only about 58% of adolescents aged 13-15 years had received two or three doses of HPV vaccine as recommended.

“The goal,” Dr. Schuchter said at the briefing, “is that younger girls and young boys get vaccinated to prevent development of HPV infection, and that should decrease the risk of cancer, which is what we’ve seen.”

Mr. DeKloe agreed and highlighted the importance of improving vaccination rates. “Identifying effective interventions that increase HPV vaccination rates is critical in reducing undue cancer burden in the United States,” Mr. DeKloe said in a statement.

The study had no funding source. Mr. DeKloe had no relevant disclosures. Dr. Hanna has disclosed relationships with Bicara Therapeutics, Bristol Myers Squibb, Coherus BioSciences, and others. Dr. Schuchter had no relevant disclosures.

The European Alliance of Associations for Rheumatology (EULAR) 2024 European Congress of Rheumatology annual meeting is about to take place in Vienna, Austria. From June 12 to 15, some of the world’s leading researchers and clinicians will convene to present and learn about data on some of the new and innovative treatments for people with rheumatic and musculoskeletal diseases (RMDs) as well as to discuss how to use and optimize existing approaches. 

Ahead of the Congress, this news organization asked the Congress Committee’s Scientific Programme Chair Caroline Ospelt, MD, PhD, and Abstract Chair Christian Dejaco, MD, PhD, MBA, to discuss some of their highlights of this year’s meeting.
 

From Bench to Bedside

“For me, the beauty at EULAR is really that you have the latest on basic research, how this can be translated in clinical trials, and then the last step would be how EULAR recommends it to be used in clinical practice,” Dr. Ospelt, professor of experimental rheumatology at University Hospital Zurich, said in an interview.

“So, if you go to EULAR continuously, you can actually follow the whole story of how novelty comes into clinical practice,” she added. 

In a separate interview, Dr. Dejaco, a consultant rheumatologist and associate professor at the Medical University of Graz in Austria, said: “There are several new drug trials that are going to be presented.” 

One of his highlights on the use of new drugs for the treatment of giant cell arteritis will be the phase 3 SELECT-GCA trial of the Janus kinase (JAK) inhibitor upadacitinib (LBA0001).

“It’s a trial that hopefully will lead to the approval of this drug in this indication,” Dr. Dejaco said.

EULAR

Late-Breaking Abstracts

Dr. Ospelt noted: “We had a lot of good late-breaking abstracts this year.” 

Some of these include: 

• Real-world data on the comparative effectiveness of five different classes of drugs used to treat psoriatic arthritis (PsA; LBA0002) 
• The 16-week results of a phase 2b/3 study with the novel interleukin (IL)–17A inhibitor izokibep in people with PsA (LBA0005)
• Data from the COSPIRIT-JIA trial on the efficacy and safety of ixekizumab (Taltz) in juvenile idiopathic arthritis (LBA0009)
• Phase 2 data on the safety and efficacy of the CD38-targeting monoclonal antibody daratumumab in systemic lupus erythematosus (LBA0007)
• Results of the phase 2 DAHLIAS study of the anti–neonatal Fc receptor monoclonal antibody nipocalimab in people with primary Sjögren disease (LBA0010) 
• Safety and immunogenicity data from a phase 1 study of an active anti–IL-6 immunotherapy in people with knee osteoarthritis (LBA0011)

The latter is “really interesting,” Dr. Ospelt said. As of now, there is no approved treatment for osteoarthritis, and there is no immunotherapy, “so this would be the first.” 

But it’s not just the late-breaker abstracts to look out for. Dr. Dejaco highlighted two abstracts that will be presented during the Abstract Plenary: 

• A phase 3 study of a new selective JAK1 inhibitor, SHR0302, in rheumatoid arthritis (OP0037)
• A multi-omics analysis and targeted gene-editing study in people with , which causes inflammatory and hematologic changes (OP0073)

Of the latter, he said, “this disease is still incompletely understood, and this abstract really helps to better understand the mechanisms underlying this disease.”
 

One to Watch: CAR T-Cell Therapy 

Dr. Ospelt said that the scientific program is about 80% clinical and 20% basic science overall. However, more sessions are being held jointly because data are starting to move from the bench to bedside. 

One of the basic science areas that has had “a real buzz” around it and is now producing results in the clinic is the use of chimeric antigen receptor (CAR) T cells. In one of the first, and perhaps aptly titled What Is New, or WIN, sessions of the congress, Georg Schett, MD, vice president of research at Friedrich-Alexander-Universität Erlangen-Nüremberg in Germany, will discuss the use of CAR T-cell therapy for inflammatory RMDs. There are also multiple abstract presentations on this topic. 

In-depth tissue analysis and prediction of treatment response is another interesting approach, Dr. Ospelt said. “I think that’s the way to go, that we come from the blood, we go into the tissue.” A “very nice” example of this approach will be presented during the Abstract Plenary session on Wednesday, June 12, looking at how synovial tissue macrophages may be able to give information on likely treatment response in treatment-naive rheumatoid arthritis (OP0062). There are also some further findings related to the tissue biopsy–driven treatment trial R4RA that are being presented at the meeting (OP0218, OP0242, and POS0351).
 

EULAR Highlighted Sessions

Among the highlighted sessions on the EULAR 2024 website is one on axial involvement in PsA and spondyloarthritis (SpA). 

“Axial involvement in psoriatic arthritis and peripheral involvement in axial spondyloarthritis is quite a hot topic at the moment,” Dr. Ospelt said. There are lots of questions: “How connected are they? How different are they? Do we need different treatment for axial involvement compared to peripheral involvement?” 

Another EULAR highlighted session is the 75th anniversary of glucocorticoid treatment, during which Past President of EULAR and Emeritus Professor of Rheumatology Josef S. Smolen, MD, will overview the “past, present, and future” of glucocorticoids in RMDs. Consultant rheumatologist Frank Buttgereit, MD, from the German Rheumatism Research Center in Berlin, will discuss the practicalities of using these drugs in clinical practice.

Dr. Dejaco noted: “Glucocorticoids have been one of the most important treatments for a very long time, and they’re still the most important treatment for the acute treatment of systemic inflammatory diseases.”

For a long time, there was no alternative to using steroids, he added, but steroid-sparing options now exist, and there will be data presented on a new type of drug that could potentially be used to control cortisol levels in the body (OP0335).
 

Recommendations and More

Dr. Ospelt and Dr. Dejaco both pointed out other sessions that are likely to be very popular, such as the first and second EULAR Recommendations sessions, a session on rheumatoid arthritis prevention, as well as the many presentations and sessions on digital health and nonpharmacologic interventions such as exercise. 

With over 5242 submitted abstracts, there is going to be no shortage of data being presented at EULAR 2024. Alongside the traditional abstract submission categories, this year there is a new clinical case reports category. 

“We had about 578 submissions for that category,” Dr. Dejaco said. There were 3315 abstracts submitted for the clinical research category, 812 for the basic and translational research category, 283 from health professionals in rheumatology, 152 from patient groups, and 102 in the field of pediatric rheumatology.
 

Join in On-Site, Watch on Demand 

EULAR 2024 reverts to an on-site–only meeting this year. Some of the more lighthearted yet educational elements of the program for those attending include the second edition of the EMEUNET Rheumatology Quiz and, new for this year, two escape rooms. These rooms will provide an interactive experience where small teams will have to solve rheumatologic conundrums in order to escape the room within the hour, Dr. Dejaco explained. There will also be a morning run on Friday, June 14. “It’s not a race, it’s simply to meet and run together,” Dr. Dejaco said. 

But if you cannot make the congress in person, the EULAR 2024 Livestream will be broadcasting throughout the congress. Anyone registered by June 30 will have on-demand access to the recorded content from June 17 until December 31, 2024. 

Abstracts for the meeting will be published as a supplement to Annals of the Rheumatic Diseases, the official journal of EULAR. 

Dr. Ospelt reported no relevant financial relationships. Dr. Dejaco has received consulting/speaker fees from AbbVie, Eli Lilly, Janssen, Sparrow, Novartis, Pfizer, Roche, Galapagos, and Sanofi.

For a long time, there was no alternative to using steroids, he added, but steroid-sparing options now exist, and there will be data presented on a new type of drug that could potentially be used to control cortisol levels in the body (OP0335).
 

Recommendations and More

Dr. Ospelt and Dr. Dejaco both pointed out other sessions that are likely to be very popular, such as the first and second EULAR Recommendations sessions, a session on rheumatoid arthritis prevention, as well as the many presentations and sessions on digital health and nonpharmacologic interventions such as exercise. 

With over 5242 submitted abstracts, there is going to be no shortage of data being presented at EULAR 2024. Alongside the traditional abstract submission categories, this year there is a new clinical case reports category. 

“We had about 578 submissions for that category,” Dr. Dejaco said. There were 3315 abstracts submitted for the clinical research category, 812 for the basic and translational research category, 283 from health professionals in rheumatology, 152 from patient groups, and 102 in the field of pediatric rheumatology.
 

Join in On-Site, Watch on Demand 

EULAR 2024 reverts to an on-site–only meeting this year. Some of the more lighthearted yet educational elements of the program for those attending include the second edition of the EMEUNET Rheumatology Quiz and, new for this year, two escape rooms. These rooms will provide an interactive experience where small teams will have to solve rheumatologic conundrums in order to escape the room within the hour, Dr. Dejaco explained. There will also be a morning run on Friday, June 14. “It’s not a race, it’s simply to meet and run together,” Dr. Dejaco said. 

But if you cannot make the congress in person, the EULAR 2024 Livestream will be broadcasting throughout the congress. Anyone registered by June 30 will have on-demand access to the recorded content from June 17 until December 31, 2024. 

Abstracts for the meeting will be published as a supplement to Annals of the Rheumatic Diseases, the official journal of EULAR. 

Dr. Ospelt reported no relevant financial relationships. Dr. Dejaco has received consulting/speaker fees from AbbVie, Eli Lilly, Janssen, Sparrow, Novartis, Pfizer, Roche, Galapagos, and Sanofi.

The addition of an anti-CD38 monoclonal antibody to the standard first-line combination treatment significantly improved outcomes in newly diagnosed, transplant-ineligible patients with multiple myeloma (MM), according to an interim analysis of an open-label, randomized, phase 3 trial.

Patients who took isatuximab (Sarclisa) plus bortezomib, lenalidomide, and dexamethasone (VRd) reached higher estimated progression-free survival at a median 59.7 months vs. those who took VRd alone (63.2% vs. 45.2%, respectively, 98.5% CI, hazard ratio [HR] = 0.60, P < .001), reported Thierry Facon, MD, professor of hematology at Lille University Hospital, France, and colleagues at the annual meeting of the American Society of Clinical Oncology in Chicago. The study was simultaneously published in The New England Journal of Medicine.

“The significant progression-free benefit observed with Sarclisa with combination therapy compared to VRd is important and encouraging for patients with newly diagnosed multiple myeloma,” Dr. Facon said in an interview. The findings demonstrated the VRd-isatuximab’s potential as “a first-in-class combination to address gaps in care for newly diagnosed multiple myeloma transplant-ineligible patients,” he said.

According to Dr. Facon, more than 180,000 people worldwide are diagnosed with MM each year, he said, making it the second-most common hematologic malignancy. 

“There is a need for new frontline therapeutic options for all MM patients,” he said. “Effective frontline therapy has the potential to modify the course of the disease, which is a key outcome for transplant-ineligible patients who often face high rates of attrition in later lines of therapy.”

For the industry-funded IMROZ study, researchers recruited patients aged 18-80 at 93 sites in 21 nations from 2017-2019. All were ineligible for transplant due to comorbidities or being aged 65 or older. Exclusions included Eastern Cooperative Oncology Group (ECOG) performance status scores of more than 2.

The subjects were randomly assigned in a 3-to-2 ratio to isatuximab-VRd (n = 265) or VRd alone (n = 181) and received four induction cycles (6 weeks per cycle) followed by 4-week cycles of continuous treatment until disease progression, unacceptable adverse event, or other criteria for discontinuation. If progression occurred, patients could be switched from the VRd-only group to the isatuximab-VRd group.

The median age in both the isatuximab-VRd and VRd groups was 72. The percentages of women were 46.0% and 48.1%, respectively, and 72.5% and 72.4%, respectively, were White. The next largest race/ethnic group was Asian (11.7% and 9.4%, respectively). Almost all had ECOG status of 0 or 1 (88.7% and 89.5%, respectively).

At study cut-off in September 2023, the percentages of subjects in the isatuximab-VRd and VRd groups who were still receiving treatment were 47.2% and 24.3%, respectively.

An intention-to-treat analysis found that the two groups had similar rates of overall response (91.3% for isatuximab-VRd vs. 92.3% for VRd), but the isatuximab-VRd group had higher complete or better response (74.7% vs. 64.1%, P = .01).

The percentage of patients who were minimal residual disease (MRD)-negative and had a complete response was also higher in the VRd-isatuximab group vs. the VRd group (55.5% vs. 40.9%, respectively, P = .003). A total of 26.0% of patients in the VRd-isatuximab group died vs. 32.6% in the VRd group; the estimated overall survival rates at 60 months were 72.3% and 66.3%, respectively, HR = 0.78, 99.97% CI).

As for adverse events, grade 5 events were more common in the VRd-isatuximab group (11.0% vs. 5.5%), as were deaths within the first 60 days of treatment (1.5% vs. 0.6%). “The difference was driven in part by different treatment exposures,” the researchers reported. Treatment-emergent events led to treatment discontinuation in 22.8% and 26.0% of patients, respectively.

“The safety and tolerability of Sarclisa observed was consistent with the established safety profile of Sarclisa and VRd with no new safety signals observed,” Dr. Facon said.

In an interview, Zandra Klippel, MD, global product head for multiple myeloma at Sanofi — the maker of isatuximab and funder of the study — said the Food and Drug Administration has accepted a priority review application for the investigational use of isatuximab in combination with VRd for the treatment of patients with transplant-ineligible, newly diagnosed MM.

“Our FDA approval date is expected on September 27, 2024,” Dr. Klippel said. “If all goes well, we anticipate launching as early as 2024 in the US and rolling out in other key countries starting in 2025 and continuing through 2026.”

Dr. Klippel added that isatuximab “continues to be evaluated in multiple ongoing phase 3 clinical trials in combination with current standard treatments across the MM treatment continuum.”

In an interview, Sagar Lonial, MD, chair and professor of hematology and medical oncology and chief medical officer at Winship Cancer Institute at Emory University in Atlanta, said the study is “important.”

However, Dr. Lonial, who is familiar with the findings but didn’t take part in the study, said it’s difficult to understand the impact of the treatment on frail patients. It appears that the combination treatment may be good for frail patients, he said, “but I need to better understand the magnitude of the benefit in that subset a little more.”

As for adverse events, he said “they are what would be expected for a trial like this.”

Pneumonia and COVID-19 infections were higher in the VRd-isatuximab group, he said, and “we know in general that vaccine responses are blocked by CD38 antibodies.” This can be managed, he said, via intravenous immunoglobulin support.

Manni Mohyuddin, MD, assistant professor at Huntsman Cancer Institute in Utah, said in an interview that the findings suggest that in older, fit patients, “you can get fairly good outcomes without use of transplant.”

In the United States, many more patients in the cohort would have been considered transplant-eligible, he said, and not eliminated from consideration for transplant due to age over 65. However, as patients age, “you get more diminishing returns for transplants,” said Dr. Mohyuddin, who is familiar with the study findings but didn’t take part in the research.

All the drugs in the new combination are FDA approved, he said, although the combination isn’t. “I suspect this will make it to our guidelines very soon and then be reimbursed by insurance companies and Medicare.”

The study was funded by Sanofi and an M.D. Anderson Cancer Center support grant. Dr. Facon has no disclosures. Other study authors report multiple ties relationships with various drug makers. Dr. Lonial disclosed ties with Takeda, Amgen, Novartis, BMS, GSK, AbbVie, Genentech, Pfizer, Regeneron, Janssen, AstraZeneca, and TG Therapeutics).

BARCELONA, SPAIN — Streptococcus pneumoniae, the bacteria that causes pneumococcal disease, is sixfold more likely to colonize adults older than 60 years who have regular contact with children than those who do not, data from a community-based study showed.

However, there is “no clear evidence of adult-to-adult transmission,” and the researchers, led by Anne L. Wyllie, PhD, from the Yale School of Public Health, New Haven, Connecticut, noted that the study results suggest “the main benefit of adult pneumococcal conjugate vaccine (PCV) immunization is to directly protect adults who are exposed to children, who still carry and transmit some vaccine-type pneumococci despite successful pediatric national immunization programs.”

The data show that relatively high pneumococcus carriage rates are seen in people who have regular contact with children, who have had contact in the previous 2 weeks, and who have had contact for extended periods, Dr. Wyllie explained.

Preschoolers in particular were found to be most likely to transmit pneumococcus to older adults. “It is the 24- to 59-month-olds who are most associated with pneumococcal carriage, more than 1- to 2-year-olds,” she reported. However, transmission rates from children younger than 1 year are higher than those from children aged 1-2 years, she added.

The findings were presented at the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) 2024 global conference, formerly known as the ECCMID conference.
 

Originally Designed to Investigate Adult-to-Adult Transmission

The researchers wanted to understand the sources and dynamics of transmission, as well as the risk factors for pneumococcal disease in older adults, to help predict the effect of PCVs in people older than 60 years.

Although “we designed the study to specifically look at transmission between adults, in the end, we were presented with a very unique scenario” — restricted social mixing as a result of the COVID pandemic — during which “no community activities were happening,” Dr. Wyllie said. Because of this, the team was able to determine “the source of acquisition or transmission to the older adults was, very likely, coming from contact with children.”

Pneumococci are commonly found in respiratory tracts of healthy people. The US Centers for Disease Control and Prevention estimated that 20%-60% of school-aged children may be colonized compared with only 5%-10% of adults without children.

The longitudinal study was conducted among household pairs, such as married couples who were both aged at least 60 years and who did not have people younger than 60 years living in the household, in New Haven over two winter seasons: 2020-2021 and 2021-2022.

Self-collected saliva samples were assessed, and surveys on social behaviors and health were completed every 2 weeks for a 10-week period (with six study visits). The saliva sampling method was used because the researchers considered it to be more effective than samples from nasopharyngeal swabs. Quantitative polymerase chain reaction assays were used to test the saliva samples for the presence of pneumococcal DNA (pneumococcus genes piaB and lytA) and the diversity of pneumococcal strains (36 serotypes were targeted).
 

Strongly Suggestive of Transmission From Children to Older Adults

Of the 121 adults living in 61 households who were enrolled in the study, 62 adults participated in both seasons. Mean age was 70.9 years (range, 60-86 years), 51% of participants were women, and 85% were White.

Overall, 52 of 1088 (4.8%) samples tested positive for pneumococcus, and 27 of 121 (22.3%) adults were colonized on at least one sampling visit. Some were colonized at multiple timepoints, and two were colonized throughout the 10-week sampling period. Of the two participants who were colonized at five of six timepoints, one reported daily contact with children younger than 5 years and children aged 5-9 years in the two study seasons. This person was also positive at three of six sampling points during the first study season.

There were five instances in which both members of the household were carriers in the same season, although not necessarily at the same timepoint. Numbers were too small to determine whether transmission had occurred between the household pairs.

Contact with a 24- to 59-month-old child (older than 2 years but younger than 5 years) had the strongest association with elevated odds of carrying pneumococcus, the authors reported in their preprint, although the frequency and intensity of contact also mattered.

At any sampled time (point prevalence), pneumococcal carriage was substantially — just over sixfold — higher among older adults who had contact with children daily or every few days (10%) than among those who had no contact with children (1.6%).

In particular, contact between adults and children younger than 5 years and children aged 5-9 years was found to lead to elevated point prevalences of 13.8% and 14.1%, respectively. Pneumococcal carriage in children older than 10 years was lower, with a point prevalence of 8.3%.

The younger the child, the greater the point prevalence; point prevalences were 13.8% for samples from children aged 1 year and younger, 10.5% for samples from children aged 1-2 years, and 17.8% for children aged 2-5 years.

Carriage prevalence was higher in older adults who reported daily contact with children (15.7%) or contact every few days (14.0%) than in those who reported contact with children only once or twice a month (4.5%) or never (1.8%), they wrote.

“Older people who have a lot of contact with kids and are more susceptible to respiratory viruses can get a secondary infection from pneumococcus, especially during the cold and flu seasons. Vaccination can help to protect them or lessen severity of the illness,” Wyllie pointed out.

However, adult PCV immunization may not have a major impact on onward transmission to other adults, the authors wrote in their preprint.

This study supports prior work demonstrating that pneumococcal colonization is greater in households with children than in those without, said Stephen Pelton, MD, a pediatric infectious disease specialist from Boston University schools of medicine and public health. “The unique aspect is that Dr. Wyllie’s group has looked at individuals over age 60 and used the most sensitive methods currently available to detect pneumococcal carriage.”

“At the most recent ISPPD [International Society of Pneumonia and Pneumococcal Diseases conference], the role of adult-to-adult transmission in the community was discussed. This study confirms the critical role children play in community transmission of the pneumococcus,” Dr. Pelton noted.

Dr. Wyllie received consulting and/or advisory board fees from Pfizer, Merck, Diasorin, PPS Health, Primary Health, Co-Diagnostics, and Global Diagnostic Systems for work unrelated to this project and is the principal investigator on research grants from Pfizer, Merck, NIH RADx-UP, and SalivaDirect, Inc. to Yale University and from NIH RADx, Balvi.io, and Shield T3 to SalivaDirect, Inc. Dr. Pelton received honoraria from Merck, Pfizer, Sanofi, and GSK for participation in Pneumococcal Advisory Boards and DSMB (Sanofi). Boston Medical Center received grant funding for investigator-initiated research from Merck and Pfizer.

Pneumococci are commonly found in respiratory tracts of healthy people. The US Centers for Disease Control and Prevention estimated that 20%-60% of school-aged children may be colonized compared with only 5%-10% of adults without children.

The longitudinal study was conducted among household pairs, such as married couples who were both aged at least 60 years and who did not have people younger than 60 years living in the household, in New Haven over two winter seasons: 2020-2021 and 2021-2022.

Self-collected saliva samples were assessed, and surveys on social behaviors and health were completed every 2 weeks for a 10-week period (with six study visits). The saliva sampling method was used because the researchers considered it to be more effective than samples from nasopharyngeal swabs. Quantitative polymerase chain reaction assays were used to test the saliva samples for the presence of pneumococcal DNA (pneumococcus genes piaB and lytA) and the diversity of pneumococcal strains (36 serotypes were targeted).
 

Strongly Suggestive of Transmission From Children to Older Adults

Of the 121 adults living in 61 households who were enrolled in the study, 62 adults participated in both seasons. Mean age was 70.9 years (range, 60-86 years), 51% of participants were women, and 85% were White.

Overall, 52 of 1088 (4.8%) samples tested positive for pneumococcus, and 27 of 121 (22.3%) adults were colonized on at least one sampling visit. Some were colonized at multiple timepoints, and two were colonized throughout the 10-week sampling period. Of the two participants who were colonized at five of six timepoints, one reported daily contact with children younger than 5 years and children aged 5-9 years in the two study seasons. This person was also positive at three of six sampling points during the first study season.

There were five instances in which both members of the household were carriers in the same season, although not necessarily at the same timepoint. Numbers were too small to determine whether transmission had occurred between the household pairs.

Contact with a 24- to 59-month-old child (older than 2 years but younger than 5 years) had the strongest association with elevated odds of carrying pneumococcus, the authors reported in their preprint, although the frequency and intensity of contact also mattered.

At any sampled time (point prevalence), pneumococcal carriage was substantially — just over sixfold — higher among older adults who had contact with children daily or every few days (10%) than among those who had no contact with children (1.6%).

In particular, contact between adults and children younger than 5 years and children aged 5-9 years was found to lead to elevated point prevalences of 13.8% and 14.1%, respectively. Pneumococcal carriage in children older than 10 years was lower, with a point prevalence of 8.3%.

The younger the child, the greater the point prevalence; point prevalences were 13.8% for samples from children aged 1 year and younger, 10.5% for samples from children aged 1-2 years, and 17.8% for children aged 2-5 years.

Carriage prevalence was higher in older adults who reported daily contact with children (15.7%) or contact every few days (14.0%) than in those who reported contact with children only once or twice a month (4.5%) or never (1.8%), they wrote.

“Older people who have a lot of contact with kids and are more susceptible to respiratory viruses can get a secondary infection from pneumococcus, especially during the cold and flu seasons. Vaccination can help to protect them or lessen severity of the illness,” Wyllie pointed out.

However, adult PCV immunization may not have a major impact on onward transmission to other adults, the authors wrote in their preprint.

This study supports prior work demonstrating that pneumococcal colonization is greater in households with children than in those without, said Stephen Pelton, MD, a pediatric infectious disease specialist from Boston University schools of medicine and public health. “The unique aspect is that Dr. Wyllie’s group has looked at individuals over age 60 and used the most sensitive methods currently available to detect pneumococcal carriage.”

“At the most recent ISPPD [International Society of Pneumonia and Pneumococcal Diseases conference], the role of adult-to-adult transmission in the community was discussed. This study confirms the critical role children play in community transmission of the pneumococcus,” Dr. Pelton noted.

Dr. Wyllie received consulting and/or advisory board fees from Pfizer, Merck, Diasorin, PPS Health, Primary Health, Co-Diagnostics, and Global Diagnostic Systems for work unrelated to this project and is the principal investigator on research grants from Pfizer, Merck, NIH RADx-UP, and SalivaDirect, Inc. to Yale University and from NIH RADx, Balvi.io, and Shield T3 to SalivaDirect, Inc.

BARCELONA, SPAIN — Streptococcus pneumoniae, the bacteria that causes pneumococcal disease, is sixfold more likely to colonize adults older than 60 years who have regular contact with children than those who do not, data from a community-based study showed.

However, there is “no clear evidence of adult-to-adult transmission,” and the researchers, led by Anne L. Wyllie, PhD, from the Yale School of Public Health, New Haven, Connecticut, noted that the study results suggest “the main benefit of adult pneumococcal conjugate vaccine (PCV) immunization is to directly protect adults who are exposed to children, who still carry and transmit some vaccine-type pneumococci despite successful pediatric national immunization programs.”

The data show that relatively high pneumococcus carriage rates are seen in people who have regular contact with children, who have had contact in the previous 2 weeks, and who have had contact for extended periods, Dr. Wyllie explained.

Preschoolers in particular were found to be most likely to transmit pneumococcus to older adults. “It is the 24- to 59-month-olds who are most associated with pneumococcal carriage, more than 1- to 2-year-olds,” she reported. However, transmission rates from children younger than 1 year are higher than those from children aged 1-2 years, she added.

The findings were presented at the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) 2024 global conference, formerly known as the ECCMID conference.
 

Originally Designed to Investigate Adult-to-Adult Transmission

The researchers wanted to understand the sources and dynamics of transmission, as well as the risk factors for pneumococcal disease in older adults, to help predict the effect of PCVs in people older than 60 years.

Although “we designed the study to specifically look at transmission between adults, in the end, we were presented with a very unique scenario” — restricted social mixing as a result of the COVID pandemic — during which “no community activities were happening,” Dr. Wyllie said.

BOSTON — The prevalence of Cushing syndrome (CS) in the United States may be considerably higher than currently appreciated, new data from a single US institution suggest. 

In contrast to estimates of 1 to 3 cases per million patient-years from population-based European studies, researchers at the University of Wisconsin, Milwaukee, estimated that the incidence of CS in Wisconsin is a minimum of 7.2 cases per million patient-years. What’s more, contrary to all previous studies, they found that adrenal Cushing syndrome was more common than pituitary adrenocorticotropic hormone (ACTH)–secreting tumors (Cushing disease), and that fewer than half of individuals with adrenal Cushing syndrome had classic physical features of hypercortisolism, such as weight gain, round face, excessive hair growth, and stretch marks.

“Cases are absolutely being missed. ... Clinicians should realize that cortisol excess is not rare. It may not be common, but it needs to be considered in patients with any constellation of features that are seen in cortisol excess,” study investigator Ty B. Carroll, MD, associate professor of medicine, endocrinology and molecular medicine, and the endocrine fellowship program director at Medical College of Wisconsin in Milwaukee, told this news organization. 

There are several contributing factors, he noted, “including the obesity and diabetes epidemics which make some clinical features of cortisol excess more common and less notable. Providers get used to seeing patients with some features of cortisol excess and don’t think to screen. The consequence of this is more difficult-to-control diabetes and hypertension, more advance metabolic bone disease, and likely more advanced cardiovascular disease, all resulting from extended exposure to cortisol excess,” he said.

 

Are Milder Cases the Ones Being Missed?

Asked to comment, session moderator Sharon L. Wardlaw, MD, professor of medicine at Columbia University College of Physicians and Surgeons, New York City, said, “When we talk about Cushing [syndrome], we usually think of pituitary ACTH as more [common], followed by adrenal adenomas, and then ectopic. But they’re seeing more adrenal adenoma ... we are probably diagnosing this a little more now.”

She also suggested that the Wisconsin group may have a lower threshold for diagnosing the milder cortisol elevation seen with adrenal Cushing syndrome. “If you screen for Cushing with a dexamethasone suppression test … [i]f you have autonomous secretion by the adrenal, you don’t suppress as much. ... When you measure 24-hour urinary cortisol, it may be normal. So you’re in this in-between [state]. ... Maybe in Wisconsin they’re diagnosing it more. Or, maybe it’s just being underdiagnosed in other places.” 

She also pointed out that “you can’t diagnose it unless you think of it. I’m not so sure that with these mild cases it’s so much that it’s more common, but maybe it’s like thyroid nodules, where we didn’t know about it until everybody started getting all of these CT scans. We’re now seeing all these incidental thyroid nodules ... I don’t think we’re missing florid Cushing.” 

However, Dr. Wardlaw said, it’s probably worthwhile to detect even milder hypercortisolism because it could still have long-term damaging effects, including osteoporosis, muscle weakness, glucose intolerance, and frailty. “You could do something about it and normalize it if you found it. I think that would be the reason to do it.”
 

Is Wisconsin Representative of Cushing Everywhere?

Dr. Carroll presented the findings at the annual meeting of the Endocrine Society. He began by noting that most of the previous CS incidence studies, with estimates of 1.2-3.2 cases per million per year, come from European data published from 1994 to 2019 and collected as far back as 1955. The method of acquisition of patients and the definitions of confirmed cases varied widely in those studies, which reported CS etiologies of ACTH-secreting neoplasms (pituitary or ectopic) in 75%-85% and adrenal-dependent cortisol excess in 15%-20%. 

The current study included data from clinic records between May 1, 2017, and December 31, 2022, of Wisconsin residents newly diagnosed with and treated for CS. The CS diagnosis was established with standard guideline-supported biochemical testing and appropriate imaging. Patients with exogenous and non-neoplastic hypercortisolism and those who did not receive therapy for CS were excluded. 

A total of 185 patients (73% female, 27% male) were identified from 27 of the total 72 counties in Wisconsin, representing a population of 4.5 million. On the basis of the total 5.9 million population of Wisconsin, the incidence of CS in the state works out to 7.2 cases per million population per year, Dr. Carroll said. 

However, data from the Wisconsin Hospital Association show that the University of Wisconsin’s Milwaukee facility treated just about half of patients in the state who are discharged from the hospital with a diagnosis of CS during 2019-2023. “So ... that means that an actual or approximate incidence of 14-15 cases per million per year rather than the 7.2 cases that we produce,” he said. 

Etiologies were 60% adrenal (111 patients), 36.8% pituitary (68 patients), and 3.2% ectopic (6 patients). Those proportions were similar between genders. 

On biochemical testing, values for late-night salivary cortisol, dexamethasone suppression, and urinary free cortisol were highest for the ectopic group (3.189 µg/dL, 42.5 µg/dL, and 1514.2 µg/24 h, respectively) and lowest for the adrenal group (0.236 µg/dL, 6.5 µg/dL, and 64.2 µg/24 h, respectively). All differences between groups were highly statistically significant, at P < .0001, Dr. Carroll noted. 

Classic physical features of CS were present in 91% of people with pituitary CS and 100% of those ectopic CS but just 44% of individuals with adrenal CS. “We found that adrenal-dependent disease was the most common form of Cushing syndrome. It frequently presented without classic physical features that may be due to the milder biochemical presentation,” he concluded. 

Dr. Carroll reported consulting and investigator fees from Corcept Therapeutics. Dr. Wardlaw has no disclosures.

The antibody-drug conjugate trastuzumab deruxtecan, or T-DXd, is an effective first-line treatment in patients with HER2-low metastatic breast cancer, conferring an additional 5 months’ progression-free survival over chemotherapy.

HER2-low cancers express levels of human epidermal growth factor receptor 2 that are below standard thresholds for HER2-positive immunohistochemistry. In 2022, results from the DESTINY-Breast04 trial showed T-DXd (Enhertu, AstraZeneca) to be an effective second-line chemotherapy in patients with HER2-low metastatic breast cancer.

The highly awaited new findings, from the manufacturer-sponsored, open-label Phase 3 DESTINY-Breast06 trial, were presented at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago, Illinois.

The findings not only definitively establish a role for T-DXd earlier in the treatment sequence for HER2-low cancers, they also suggest benefit in a group of patients designated for the purposes of this trial to be HER2-ultralow. These patients have cancers with only faintly detectable HER2 expression on currently used assays (J Clin Oncol 42, 2024 [suppl 17; abstr LBA 1000]).

In a separate set of findings also presented at ASCO, from the randomized phase 1B open-label study, DESTINY-Breast07, T-Dxd showed efficacy in previously untreated HER2-positive metastatic breast cancer patients both alone and in combination with the monoclonal antibody pertuzumab (Perjeta, Genentech).
 

DESTINY-Breast06 Methods and Results

The DESTINY-Breast06 findings were presented by lead investigator Guiseppe Curigliano, MD, PhD, of the University of Milan and European Institute of Oncology. Dr. Curigliano and his colleagues randomized 866 patients with metastatic breast cancer: 436 to intravenous T-Dxd and 430 to the investigator’s choice of capecitabine, nab-paclitaxel, or paclitaxel chemotherapy. The investigators chose capecitabine 60% of the time.

Most patients had cancers classed as HER2 low (immunohistochemistry 1+ or 2+), while 153 had cancers classed by investigators as HER2-ultralow (IHC 0 with membrane staining or IHC under 1+). Patients enrolled in the study were those whose disease had progressed after endocrine therapy with or without targeted therapy. Patients’ median age was between 57 and 58, and all were chemotherapy-naive in the metastatic breast cancer setting.

The main outcome of the study was median progression-free survival in the HER2-low group. T-Dxd was seen improving progression-free survival, with median 13.2 months vs. 8.1 months (hazard ratio, 0.62; 95% confidence interval, 0.51-0.74; P < .0001). In the intention-to-treat population, which included the HER2 ultralow patients, the benefit was the same (HR, 0.63; 95% CI, 0.53-0.75; P < .0001). This suggested that T-DXd is also effective in these patients, and it will be extremely important going forward to identify the lowest level of HER2 expression in metastatic breast cancers that can still benefit from therapy with T-DxD, Dr. Curigliano said.

Overall survival could not be assessed in the study cohort because complete data were not yet available, Dr. Curigliano said. However, trends pointed to an advantage for T-DXd, and tumor response rates were markedly higher with T-DXd: 57% compared with 31% for standard chemotherapy in the full cohort.

Serious treatment-emergent adverse events were more common in the T-Dxd–treated patients, with 11% of that arm developing drug-related interstitial lung disease, and three patients dying of it. Five patients in the T-DXd arm died of adverse events deemed treatment-related, and none died from treatment-related adverse events in the standard chemotherapy arm. Altogether 11 patients died in the T-DXd arm and 6 in the chemotherapy arm.
 

Clinical Implications of DESTINY-Breast06

The DESTINY-Breast06 data show that “we have to again change how we think about HER2 expression. Even very low levels of HER2 expression matter, and they can be leveraged to improve the treatment for our patients,” said Ian Krop, MD, PhD, of the Yale Cancer Center in New Haven, Connecticut, during the session where the results were presented.

But T-DXd may not be an appropriate first choice for all patients, especially given the safety concerns associated with T-DXd, he continued. With overall survival and quality-of-life data still lacking, clinicians will have to determine on a case-by-case basis who should get T-DXd in the first line.

“For patients who have symptomatic metastatic disease, who need a response to address those symptoms, those in whom you think chemotherapy may not work as well because they had, for example, a short recurrence interval after their adjuvant chemotherapy — using T-DXd in that first-line setting makes perfect sense to take advantage of the substantially higher response rate compared to chemo,” Dr. Krop said. “But for patients who have asymptomatic low burdens of disease, it seems very reasonable to consider using a well-tolerated chemotherapy like capecitabine in the first line, and then using T-DXd in the second line.”

In an interview, Erica Mayer, MD, of the Dana Farber Cancer Institute in Boston, Massachusetts, said patient choice will also matter in determining whether T-DXd is a first-line option. The known toxicity of T-DXd was underscored by the latest findings, she noted, while capecitabine, one of the chemotherapy choices in the control arm of the study, “really reflects what the majority of breast cancer doctors tend to offer, both because of the efficacy of the drug, but also because it’s oral, it’s well tolerated, and you don’t lose your hair.”
 

DESTINY-Breast07 Results

The DESTINY-Breast07 findings, from a Phase 1B open-label trial measuring safety and tolerability, were presented by Fabrice Andre, MD, PhD, of Université Paris Saclay in Paris, France. Dr. Andre and his colleagues presented the first data comparing T-DXd monotherapy and T-DXd with pertuzumab — a monoclonal antibody targeting HER2 — as a first-line treatment in patients with HER2-overexpressing (immunohistochemistry 3 and above) metastatic breast cancer. (J Clin Oncol 42, 2024 [suppl 16; abstr 1009]).

Current first-line standard of care for these patients is pertuzumab, trastuzumab, and docetaxel, based on results from the 2015 CLEOPATRA trial. T-DXd is currently approved as a second-line treatment.

Dr. Andre and his colleagues randomized 75 patients to monotherapy with T-DXd and 50 to combined therapy, with a median follow-up of 2 years.

After 1 year of treatment, combination of T-DXd and pertuzumab was seen to be associated with a progression-free survival of 89% at 1 year (80% CI, 81.9-93.9), compared with 80% in patients treated with T-DXd alone (80% CI, 73.7-86.1). Objective tumor response rate was 84% for the combined therapy at 12 weeks, with 20% of patients seeing a complete response, compared with 76% and 8%, respectively, for monotherapy.

As in the DESTINY-Breast06 trial, adverse events were high, with interstitial lung disease seen in 9% of patients in the monotherapy group and in 14% of the combined-therapy patients, although no treatment-related deaths occurred.

A randomized phase 3 trial, DESTINY Breast09, will now compare the monotherapy and the combined therapy with standard care.

T-DXd has seen a rapidly expanding role in treating breast and other solid tumors. The DESTINY Breast06 findings will move up its place in the treatment algorithm for metastatic breast cancer, “allowing us to now offer T-DXd as the first chemotherapy choice for patients who are making that transition to chemotherapy over many of the traditional provider choices that we previously have offered,” Dr. Mayer said.

The results “support the use of not only this specific agent, but also the concept of antibody drug conjugates as a very effective way to treat malignancy,” she added.

Dr. Curigliano reported receiving speaker’s fees, research funding, and other support from AstraZeneca and Daiichi Sankyo, among other companies, as did most of his co-authors, of whom three were AstraZeneca employees. Dr. Fabrice disclosed receiving research funding, travel compensation, and/or advisory fees from AstraZeneca and other entities, as did several of his co-authors. Two of his co-authors were employed by AstraZeneca and Roche, manufacturers of the study drugs. Dr. Krop and Dr. Mayer disclosed relationships with AstraZeneca and others.

The antibody-drug conjugate trastuzumab deruxtecan, or T-DXd, is an effective first-line treatment in patients with HER2-low metastatic breast cancer, conferring an additional 5 months’ progression-free survival over chemotherapy.

HER2-low cancers express levels of human epidermal growth factor receptor 2 that are below standard thresholds for HER2-positive immunohistochemistry. In 2022, results from the DESTINY-Breast04 trial showed T-DXd (Enhertu, AstraZeneca) to be an effective second-line chemotherapy in patients with HER2-low metastatic breast cancer.

The highly awaited new findings, from the manufacturer-sponsored, open-label Phase 3 DESTINY-Breast06 trial, were presented at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago, Illinois.

The findings not only definitively establish a role for T-DXd earlier in the treatment sequence for HER2-low cancers, they also suggest benefit in a group of patients designated for the purposes of this trial to be HER2-ultralow. These patients have cancers with only faintly detectable HER2 expression on currently used assays (J Clin Oncol 42, 2024 [suppl 17; abstr LBA 1000]).

In a separate set of findings also presented at ASCO, from the randomized phase 1B open-label study, DESTINY-Breast07, T-Dxd showed efficacy in previously untreated HER2-positive metastatic breast cancer patients both alone and in combination with the monoclonal antibody pertuzumab (Perjeta, Genentech).
 

DESTINY-Breast06 Methods and Results

The DESTINY-Breast06 findings were presented by lead investigator Guiseppe Curigliano, MD, PhD, of the University of Milan and European Institute of Oncology. Dr. Curigliano and his colleagues randomized 866 patients with metastatic breast cancer: 436 to intravenous T-Dxd and 430 to the investigator’s choice of capecitabine, nab-paclitaxel, or paclitaxel chemotherapy. The investigators chose capecitabine 60% of the time.

Most patients had cancers classed as HER2 low (immunohistochemistry 1+ or 2+), while 153 had cancers classed by investigators as HER2-ultralow (IHC 0 with membrane staining or IHC under 1+). Patients enrolled in the study were those whose disease had progressed after endocrine therapy with or without targeted therapy. Patients’ median age was between 57 and 58, and all were chemotherapy-naive in the metastatic breast cancer setting.

The main outcome of the study was median progression-free survival in the HER2-low group. T-Dxd was seen improving progression-free survival, with median 13.2 months vs. 8.1 months (hazard ratio, 0.62; 95% confidence interval, 0.51-0.74; P < .0001). In the intention-to-treat population, which included the HER2 ultralow patients, the benefit was the same (HR, 0.63; 95% CI, 0.53-0.75; P < .0001).

Five patients in the T-DXd arm died of adverse events deemed treatment-related, and none died from treatment-related adverse events in the standard chemotherapy arm. Altogether 11 patients died in the T-DXd arm and 6 in the chemotherapy arm.

Some vitamin D tests may give misleading results despite progress made in recent years to improve the quality of these assays, according to the US Centers for Disease Control and Prevention (CDC).

Otoe Sugahara manager of the CDC Vitamin D Standardization-Certification Program (VDSCP), presented an update of her group’s work at ENDO 2024, the Endocrine Society’s annual meeting in Boston. 

“Though most vitamin D tests in our program have improved, there still remain some sample-specific inaccuracies. The CDC is working with program participants to address these situations,” Ms. Sugahara said in a statement released by the Endocrine Society.

For example, some assays measure other compounds besides 25-hydroxyvitamin D, which can falsely elevate results of some blood samples, Ms. Sugahara reported. Thus, some tests may be misclassified, with results seen as sufficient from samples that should have indicated a vitamin D deficiency.

“While most vitamin D tests are effective, it is important for healthcare providers to be aware of the potential inconsistencies associated with vitamin D tests to avoid misclassification of the patients,” Ms. Sugahara and coauthors said in an abstract provided by the Endocrine Society.

Ms. Sugahara’s report provided a snapshot of the state of longstanding efforts to improve the quality of a widely performed service in US healthcare: testing vitamin D levels.

These include an international collaboration that gave rise in 2010 to a vitamin D standardization program, from which the CDC’s VDSCP certification emerged. Among the leaders of these efforts was Christopher Sempos, PhD, then with the Office of Dietary Supplements at the National Institutes of Health.

Many clinicians may not be aware of the concerns about the accuracy of vitamin D tests that led to the drive for standardization, Dr. Sempos, now retired, said in an interview. And, in his view, it’s something that busy practitioners should not have to consider.

“They have literally thousands of diseases they have to be able to recognize and diagnose,” Dr. Sempos said. “They should be able to count on the laboratory system to give them accurate and precise data.”
 

‘Nudging’ Toward Better Results

The CDC’s certification program gives labs and companies detailed information about the analytical accuracy and precision of their vitamin D tests. 

This feedback has paid off with improved results, Andy Hoofnagle, MD, PhD, professor of laboratory medicine and pathology at the University of Washington in Seattle, told this news organization. It helps by “nudging manufacturers in the right direction,” he said.

“Some manufacturers reformulated, others recalibrated, which is a lot of effort on their part, so that when the patient get a number, it actually means the right thing,” said Dr. Hoofnagle, who is also chair of the Accuracy-Based Programs Committee of the College of American Pathologists.

“There are still many immunoassays on the market that aren’t giving the correct results, unfortunately, but the standardization certification program has really pushed the field in the right direction,” he said.

US scientists use two main types of technologies to measure vitamin D in the blood, Ms. Sugahara said. One is mass spectrometry, which separately measures 25-hydroxyvitamin D2 and D3 and sums the values. The other type, immunoassay, measures both compounds at the same time and reports one result for total 25-hydroxyvitamin D.

At the ENDO 2024 meeting, Ms. Sugahara reported generally positive trends seen in the VDSCP. For example, the program looks at specific tests’ bias, or the deviation of test results from the true value, as determined with the CDC’s reference method for vitamin D.

Average calibration bias was less than 1% for all assays in the VDSCP in 2022, Ms. Sugahara said. The average calibration bias for immunoassays was 0.86%, and for assays using mass spectrometry, it was 0.55%, Ms. Sugahara reported. 

These are improved results compared with 2019 data, in which mass spectrometry–based assays had a mean bias of 1.9% and immunoassays had a mean bias of 2.4%, the CDC told this news organization in an email exchange.

The CDC said the VDSCP supports laboratories and researchers from around the world, including ones based in the US, China, Australia, Japan, and Korea.
 

Call for Research

Vitamin D tests are widely administered despite questions about their benefit for people who do not appear likely to be deficient of it. 

The Endocrine Society’s newly released practice guideline recommends against routine testing of blood vitamin D levels in the general population.

Laboratory testing has increased over the years owing to studies reporting associations between blood vitamin D [25(OH)D] levels and a variety of common disorders, including musculoskeletal, metabolic, cardiovascular, malignant, autoimmune, and infectious diseases, wrote Marie B. Demay, MD, of Harvard Medical School in Boston, and coauthors in the new guideline. It was published on June 3 in The Journal of Clinical Endocrinology & Metabolism.

‘”Although a causal link between serum 25(OH)D concentrations and many disorders has not been clearly established, these associations have led to widespread supplementation with vitamin D and increased laboratory testing for 25(OH)D in the general population,” they wrote.

It’s uncertain that “any putative benefits of screening would outweigh the increased burden and cost, and whether implementation of universal 25(OH)D screening would be feasible from a societal perspective,” Dr. Demay and coauthors added.

They noted that the influential US Preventive Services Task Force also has raised doubts about widespread use of vitamin D tests. 

The USPSTF has a somewhat different take from the Endocrine Society. The task force in 2021 reiterated its view that there is not enough evidence to recommend for or against widespread vitamin D testing for adults. The task force gave this test an I grade, meaning there is insufficient evidence to weigh the risks and benefits. That’s the same grade the task force gave it in 2014.

The USPSTF uses a grade of D to recommend against use of a test or service.

In an interview with this news organization, John Wong, MD, vice chair of the USPSTF, reiterated his group’s call for more research into the potential benefits and harms of vitamin D screening. 

One of the challenges in addressing this issue, Dr. Wong noted, has been the variability of test results. Therefore, efforts such as the CDC’s VDSCP in improving test quality may help in eventually building up the kind of evidence base needed for the task force to offer a more definitive judgment on the tests, he said.

Wong acknowledged it must be frustrating for clinicians and patients to hear that experts don’t have the evidence needed to make a broad call about whether routine vitamin D tests are beneficial.

“We really would like to have that evidence because we recognize that it’s an important health question to help everybody in this nation stay healthy and live longer,” Dr. Wong said.

These are improved results compared with 2019 data, in which mass spectrometry–based assays had a mean bias of 1.9% and immunoassays had a mean bias of 2.4%, the CDC told this news organization in an email exchange.

The CDC said the VDSCP supports laboratories and researchers from around the world, including ones based in the US, China, Australia, Japan, and Korea.
 

Call for Research

Vitamin D tests are widely administered despite questions about their benefit for people who do not appear likely to be deficient of it. 

The Endocrine Society’s newly released practice guideline recommends against routine testing of blood vitamin D levels in the general population.

Laboratory testing has increased over the years owing to studies reporting associations between blood vitamin D [25(OH)D] levels and a variety of common disorders, including musculoskeletal, metabolic, cardiovascular, malignant, autoimmune, and infectious diseases, wrote Marie B. Demay, MD, of Harvard Medical School in Boston, and coauthors in the new guideline. It was published on June 3 in The Journal of Clinical Endocrinology & Metabolism.

‘”Although a causal link between serum 25(OH)D concentrations and many disorders has not been clearly established, these associations have led to widespread supplementation with vitamin D and increased laboratory testing for 25(OH)D in the general population,” they wrote.

It’s uncertain that “any putative benefits of screening would outweigh the increased burden and cost, and whether implementation of universal 25(OH)D screening would be feasible from a societal perspective,” Dr. Demay and coauthors added.

They noted that the influential US Preventive Services Task Force also has raised doubts about widespread use of vitamin D tests. 

The USPSTF has a somewhat different take from the Endocrine Society. The task force in 2021 reiterated its view that there is not enough evidence to recommend for or against widespread vitamin D testing for adults. The task force gave this test an I grade, meaning there is insufficient evidence to weigh the risks and benefits. That’s the same grade the task force gave it in 2014.

The USPSTF uses a grade of D to recommend against use of a test or service.

In an interview with this news organization, John Wong, MD, vice chair of the USPSTF, reiterated his group’s call for more research into the potential benefits and harms of vitamin D screening. 

One of the challenges in addressing this issue, Dr. Wong noted, has been the variability of test results. Therefore, efforts such as the CDC’s VDSCP in improving test quality may help in eventually building up the kind of evidence base needed for the task force to offer a more definitive judgment on the tests, he said.

Wong acknowledged it must be frustrating for clinicians and patients to hear that experts don’t have the evidence needed to make a broad call about whether routine vitamin D tests are beneficial.

“We really would like to have that evidence because we recognize that it’s an important health question to help everybody in this nation stay healthy and live longer,” Dr. Wong said.

Some vitamin D tests may give misleading results despite progress made in recent years to improve the quality of these assays, according to the US Centers for Disease Control and Prevention (CDC).

Otoe Sugahara manager of the CDC Vitamin D Standardization-Certification Program (VDSCP), presented an update of her group’s work at ENDO 2024, the Endocrine Society’s annual meeting in Boston. 

“Though most vitamin D tests in our program have improved, there still remain some sample-specific inaccuracies. The CDC is working with program participants to address these situations,” Ms. Sugahara said in a statement released by the Endocrine Society.

For example, some assays measure other compounds besides 25-hydroxyvitamin D, which can falsely elevate results of some blood samples, Ms. Sugahara reported. Thus, some tests may be misclassified, with results seen as sufficient from samples that should have indicated a vitamin D deficiency.

“While most vitamin D tests are effective, it is important for healthcare providers to be aware of the potential inconsistencies associated with vitamin D tests to avoid misclassification of the patients,” Ms. Sugahara and coauthors said in an abstract provided by the Endocrine Society.

Ms. Sugahara’s report provided a snapshot of the state of longstanding efforts to improve the quality of a widely performed service in US healthcare: testing vitamin D levels.

These include an international collaboration that gave rise in 2010 to a vitamin D standardization program, from which the CDC’s VDSCP certification emerged. Among the leaders of these efforts was Christopher Sempos, PhD, then with the Office of Dietary Supplements at the National Institutes of Health.

Many clinicians may not be aware of the concerns about the accuracy of vitamin D tests that led to the drive for standardization, Dr. Sempos, now retired, said in an interview. And, in his view, it’s something that busy practitioners should not have to consider.

“They have literally thousands of diseases they have to be able to recognize and diagnose,” Dr. Sempos said. “They should be able to count on the laboratory system to give them accurate and precise data.”
 

‘Nudging’ Toward Better Results

The CDC’s certification program gives labs and companies detailed information about the analytical accuracy and precision of their vitamin D tests. 

This feedback has paid off with improved results, Andy Hoofnagle, MD, PhD, professor of laboratory medicine and pathology at the University of Washington in Seattle, told this news organization. It helps by “nudging manufacturers in the right direction,” he said.

“Some manufacturers reformulated, others recalibrated, which is a lot of effort on their part, so that when the patient get a number, it actually means the right thing,” said Dr. Hoofnagle, who is also chair of the Accuracy-Based Programs Committee of the College of American Pathologists.

“There are still many immunoassays on the market that aren’t giving the correct results, unfortunately, but the standardization certification program has really pushed the field in the right direction,” he said.

US scientists use two main types of technologies to measure vitamin D in the blood, Ms. Sugahara said. One is mass spectrometry, which separately measures 25-hydroxyvitamin D2 and D3 and sums the values. The other type, immunoassay, measures both compounds at the same time and reports one result for total 25-hydroxyvitamin D.

At the ENDO 2024 meeting, Ms. Sugahara reported generally positive trends seen in the VDSCP. For example, the program looks at specific tests’ bias, or the deviation of test results from the true value, as determined with the CDC’s reference method for vitamin D.

Average calibration bias was less than 1% for all assays in the VDSCP in 2022, Ms. Sugahara said. The average calibration bias for immunoassays was 0.86%, and for assays using mass spectrometry, it was 0.55%, Ms. Sugahara reported.

Dual therapy of ibrutinib (Imbruvica) and venetoclax (Venclexta) produced “promising” and comparable efficacy across cohorts of patients with mantle cell lymphoma (MCL) and TP53 mutations, a new analysis of the randomized, double-blind, phase 3 Sympatico study finds.

In first-line patients (n = 29) and relapsed/refractory patients (n = 45) with TP53 mutations, complete response rates were 55% and 58%, respectively, reported hematologist-oncologist Michael Wang, MD, of the University of Texas MD Anderson Cancer Center, and colleagues, at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago.

“These results are encouraging in light of the poor responses and shorter survival outcomes with standard chemotherapy,” Dr. Wang said in an ASCO presentation.

The current standard of care for relapsed/refractory MCL includes Bruton tyrosine kinase inhibitors for first relapse and CAR T-cell therapy (CAR-T) for second relapse in eligible patients or pirtobrutinib (Jaypirca) in patients ineligible for CAR T-cell therapy, Ohio State University Comprehensive Cancer Center hematology specialist Narendranath Epperla, MD, MS, said in an interview. Dr. Epperla is familiar with the new study findings but didn’t take part in the research.

Options for third relapse and beyond include clinical trial, rituximab [Rituxan] and lenalidomide [Revlimid], and bortezomib [Velcade],” Dr. Epperla said. “Venetoclax is not currently FDA-approved but can also be considered at third relapse.”

Better therapies are needed for a number of reasons, including poor outcomes in high-risk patients, such as those with TP53 mutations and those who progress following CAR T, Dr. Epperla said. Also, “as the novel agents are being moved into earlier lines of therapy, there remains an unmet need in those who progress on these agents with fewer options in the relapsed setting.”

At last December’s American Society of Hematology annual meeting, Dr. Wang and colleagues reported on the primary analysis results from the Sympatico study. Patients with relapsed/refractory MCL after 1-5 prior therapies were randomly assigned to receive 560 mg of ibrutinib once daily with either placebo (n = 133) or 400 mg daily of venetoclax after ramp-up (n = 134) for 2 years. Then subjects continued taking ibrutinib alone until their disease progressed or they reached unacceptable toxicity.

At a median follow-up of 51.2 months, median progression-free survival was longer in the ibrutinib-venetoclax group vs. ibrutinib alone (hazard ratio [HR] = 0.65, 95% CI, P = .0052).

The new analysis pools several cohorts of patients with TP53 mutations who all took the combination therapy: 5 from a safety run-in phase, 40 from the randomized phase, and 29 from a first-line cohort (median age at baseline = 67).

Median overall survival was not reached in the first-line group and 35.0 months in the relapsed/refractory group (total = 47.1 months). Median progress-free survival in the groups was 22.0 months and 20.9 months, respectively, and median duration of response was 20.5 months and 26.5 months, respectively.

With regard to the new findings, “it is good to see the responses with ibrutinib and venetoclax were deep and durable,” Dr. Epperla said. The combination treatment “provides a good alternative option for TP53-mutated MCL patients who are ineligible for CAR-T.”

Dr. Epperla added that the findings about the addition of ibrutinib could apply to newer-generation Bruton tyrosine kinase inhibitors that have relatively better safety profiles.

However, Dr. Epperla cautioned that the treatment needs to be weighed against the toxicity and cost of the regimen of ibrutinib and venetoclax for 2 years then single-agent ibrutinib until progression or unacceptable toxicity.

This news organization reported in 2023 that estimated net spending on ibrutinib per Medicare data increased by nearly half from 2014-2020, reaching $11,980 in 2020 vs. $7,787 for venetoclax.

Dr. Epperla also noted that “there are newer therapies that are emerging, such as T-cell-engaging bispecific antibodies, and they have shown promising results.”

In an interview, Brad S. Kahl, MD, a hematologist-oncologist at Washington University, St. Louis, said the improvement in outcomes are “modestly significant.”

Dr. Kahl, who is familiar with the study findings but didn’t take part in the research, said it is “worth adding the venetoclax, particularly in these biologically high risk patients with p53 mutations. Venetoclax is not FDA-approved, so insurance approval will need to be determined on a case-by-case basis. The combination is very expensive.”

Dr. Kahl agreed with Dr. Epperla that the findings could be extrapolated to other Bruton tyrosine kinase inhibitors.

The study was funded by Pharmacyclics, an AbbVie Company. Dr. Epperla disclosed relationships with BeiGene and Eli Lilly. Dr. Kahl reported ties with AstraZeneca, BeiGene, Abbvie, and Genentech.

In just 4 years, there’s been a significant evolution in the profile of pediatric and young adult patients who’ve taken the chimeric antigen receptor (CAR) T-cell immunotherapy known as tisagenlecleucel (Kymriah) for relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL), a new industry-funded study finds.

It’s becoming more common for patients with less severe disease to undergo the treatment, often bypassing hematopoietic stem cell transplantation (HSCT), and survival is on the rise.

From 2018 to 2022, the percentage of patients in an international cohort who had disease burden of ≥50% fell from 18% to 4%, researchers reported at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago. Median relapse-free survival in patients who didn’t undergo post-infusion HSCT grew from 18 months in 2018 to 27 months in 2020. It was not estimable in 2021.

“This introduction of the therapy is changing the treatment landscape of how we look at refractory B-ALL, where the standard of care previously would be to proceed to transplant. This therapy is actually reducing the use of transplant, which has lots of morbidity and mortality associated with it,” Texas Children’s Cancer Center hematologist-oncologist Rayne H. Rouce, MD, who led the study, said in an interview.

Tisagenlecleucel received Food and Drug Administration approval in 2017, said Nirali N. Shah, MD, MHSc, head of the Pediatric Oncology Branch’s Hematologic Malignancies Section at the National Cancer Institute, in an interview. Dr. Shah is familiar with the study findings but didn’t take part in the research.

Remission rates have been around 60%-70%, Dr. Shah said, although that rate is “likely higher” now because of gains in experience and improvement in disease burden prior to therapy. 

The new findings fill a knowledge gap about real-world outcomes since a lot of the prior data was based on investigational CAR T-cell products, she said.

The noninterventional, prospective, longitudinal study, funded by tisagenlecleucel manufacturer Novartis, tracked 974 patients up to age 25 who received tisagenlecleucel in the United States, Canada, Korea, and Taiwan.

The study found that between 2018 and 2022:

• The percentage of patients who received treatment while in morphological complete remission grew from 34% to 51%.
• The percentages who were in third or greater relapse fell from 14% to 2%.
• The percentages undergoing ≥1 HSCT before tisagenlecleucel infusion fell from 37% to 15%.
• Overall, 34.5% of 911 patients received post-infusion HSCT.

In the big picture, the findings suggest that the therapy can be considered more than “a last resort for patients in a second or greater relapse or who are refractory,” Dr. Rouce said. By offering CAR T-cell therapy to earlier-stage patients, she said, “when they’re less sick, when they have less comorbidities, and when their organs are functioning better, we could potentially save them from having to go on to a transplant.”

Dr. Shah said the findings indicate that “a substantial number of patients are surviving. It’s remarkable actually. Prior to tisagenlecleucel, patients had dismal outcomes from standard chemotherapy.”

She added that the study suggests “providers are getting much more comfortable with getting their patients in the best shape prior to getting CAR T-cell therapy. Outcomes are improving as providers expand the use of CAR T-cell therapy to patients who are less heavily pretreated and have lower disease burden.”

Moving forward, “at some point there will likely be a plateau in terms of how good the outcomes can be.” And there will be discussion of the role of HSCT.

“We’ll figure out some of the nuances about which patients need transplants and which can avoid them. But curative potential is growing. With or without transplant, this is ultimately going to lead to a much higher fraction of patients being cured who previously would not have been cured,” she said. “That’s the bottom line.”

As for adverse effects, Dr. Shah said “disease burden has a pretty direct relationship with side effects and toxicities. If you have more disease, you have more severe side effects.”

Reducing disease burden will reduce side effects, she said. Also, “we’re getting a lot better at managing these toxicities. Eliminating some of the more toxic chemotherapy through earlier use of CAR T-cells in chemotherapy-refractory patients may well help reduce therapy burden and improve long-term survival outcomes, she added.

As for cost, drugs.com reports that the therapy runs to more than $612,000 per infusion. But Dr. Shah said insurers are covering the treatment. She added that there are efforts to expand the indication so CAR T-cell therapy can be used earlier in patients who are chemotherapy-refractory.

Novartis funded the study. Dr. Shah discloses ties with Lentigen, VOR, and CARGO, ImmunoACT, and Sobi. Dr. Rouce reports relationships with Pfizer and Novartis.

Dr. Shah said the findings indicate that “a substantial number of patients are surviving. It’s remarkable actually. Prior to tisagenlecleucel, patients had dismal outcomes from standard chemotherapy.”

She added that the study suggests “providers are getting much more comfortable with getting their patients in the best shape prior to getting CAR T-cell therapy. Outcomes are improving as providers expand the use of CAR T-cell therapy to patients who are less heavily pretreated and have lower disease burden.”

Moving forward, “at some point there will likely be a plateau in terms of how good the outcomes can be.” And there will be discussion of the role of HSCT.

“We’ll figure out some of the nuances about which patients need transplants and which can avoid them. But curative potential is growing. With or without transplant, this is ultimately going to lead to a much higher fraction of patients being cured who previously would not have been cured,” she said. “That’s the bottom line.”

As for adverse effects, Dr. Shah said “disease burden has a pretty direct relationship with side effects and toxicities. If you have more disease, you have more severe side effects.”

Reducing disease burden will reduce side effects, she said. Also, “we’re getting a lot better at managing these toxicities. Eliminating some of the more toxic chemotherapy through earlier use of CAR T-cells in chemotherapy-refractory patients may well help reduce therapy burden and improve long-term survival outcomes, she added.

As for cost, drugs.com reports that the therapy runs to more than $612,000 per infusion. But Dr. Shah said insurers are covering the treatment. She added that there are efforts to expand the indication so CAR T-cell therapy can be used earlier in patients who are chemotherapy-refractory.

In just 4 years, there’s been a significant evolution in the profile of pediatric and young adult patients who’ve taken the chimeric antigen receptor (CAR) T-cell immunotherapy known as tisagenlecleucel (Kymriah) for relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL), a new industry-funded study finds.

It’s becoming more common for patients with less severe disease to undergo the treatment, often bypassing hematopoietic stem cell transplantation (HSCT), and survival is on the rise.

From 2018 to 2022, the percentage of patients in an international cohort who had disease burden of ≥50% fell from 18% to 4%, researchers reported at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago. Median relapse-free survival in patients who didn’t undergo post-infusion HSCT grew from 18 months in 2018 to 27 months in 2020. It was not estimable in 2021.

“This introduction of the therapy is changing the treatment landscape of how we look at refractory B-ALL, where the standard of care previously would be to proceed to transplant. This therapy is actually reducing the use of transplant, which has lots of morbidity and mortality associated with it,” Texas Children’s Cancer Center hematologist-oncologist Rayne H. Rouce, MD, who led the study, said in an interview.

Tisagenlecleucel received Food and Drug Administration approval in 2017, said Nirali N. Shah, MD, MHSc, head of the Pediatric Oncology Branch’s Hematologic Malignancies Section at the National Cancer Institute, in an interview. Dr. Shah is familiar with the study findings but didn’t take part in the research.

Remission rates have been around 60%-70%, Dr. Shah said, although that rate is “likely higher” now because of gains in experience and improvement in disease burden prior to therapy. 

The new findings fill a knowledge gap about real-world outcomes since a lot of the prior data was based on investigational CAR T-cell products, she said.

The noninterventional, prospective, longitudinal study, funded by tisagenlecleucel manufacturer Novartis, tracked 974 patients up to age 25 who received tisagenlecleucel in the United States, Canada, Korea, and Taiwan.

The study found that between 2018 and 2022:

• The percentage of patients who received treatment while in morphological complete remission grew from 34% to 51%.
• The percentages who were in third or greater relapse fell from 14% to 2%.
• The percentages undergoing ≥1 HSCT before tisagenlecleucel infusion fell from 37% to 15%.
• Overall, 34.5% of 911 patients received post-infusion HSCT.

In the big picture, the findings suggest that the therapy can be considered more than “a last resort for patients in a second or greater relapse or who are refractory,” Dr. Rouce said. By offering CAR T-cell therapy to earlier-stage patients, she said, “when they’re less sick, when they have less comorbidities, and when their organs are functioning better, we could potentially save them from having to go on to a transplant.”

Non-respiratory symptoms including poor sleep, fatigue, pain, anxiety, and depressive symptoms were prevalent among adults with cystic fibrosis (AwCF) and persisted after 1 year of follow-up, based on data from more than 200 individuals in a study presented at the American Thoracic Society (ATS) 2024 International Conference.

“People with cystic fibrosis have qualitatively reported burden from extrapulmonary symptoms that were not being addressed by their health care providers; this is the first study to examine these symptoms concurrently in a large sample over time,” said lead author Kristin A. Riekert, PhD, of Johns Hopkins University, Baltimore, in an interview.

Previous cross-sectional studies have shown a high prevalence of poor sleep quality, fatigue, pain, depression, and anxiety among AwCF, but longitudinal data showing the persistence of symptoms are lacking, Dr. Riekert and colleagues noted in their abstract.
 

Sleep Quality, Anxiety, and Other Assessments

The researchers recruited a total of 236 AwCF aged 18 years and older from two cystic fibrosis (CF) centers between April 2021 and August 2022. They examined the prevalence of poor sleep quality, fatigue pain, depression, and anxiety in AwCF on the basis of five assessments: At baseline and at 3, 6, 9, and 12 months.

Participants were assessed via an online survey using the Fatigue Severity Scale (cutoff, > 4), Pittsburgh Sleep Quality Index (cutoff, > 5), Patient Health Questionnaire (cutoff, > 9), Generalized Anxiety Disorder (cutoff, > 9), and PROMIS Pain Intensity (cutoff, > 50 T score). Chronic symptoms were defined as positive scores on four or more assessments for individuals who completed four or five time-point assessments. The mean age of the participants was 37 years, 52% were women, 95% were non-Hispanic White, and 86% had been prescribed CF modulator therapy.

At 12 months, 62% of participants reported poor sleep, and 34% reported fatigue. In addition, 17% reported depressive symptoms, 14% reported anxiety symptoms, and 7% reported pain at 12 months.

Overall, 49% of participants met the criteria for chronic poor sleep quality, and 29% met the criteria for chronic fatigue, with positive assessments at four or more time points over the course of a year. In addition, 40%, 30%, and 18% of participants reported taking medication in the past 7 days for pain, mental health, and sleep, respectively.

The findings suggest that patients with CF might benefit from routine assessments of non-pulmonary symptoms in clinical care and from access to health care providers, including mental health professionals, to address non-pulmonary concerns, the researchers wrote in their abstract.

“We delayed starting the study until elexacaftor/tezacaftor/ivacaftor (ETI) was FDA-approved because there was an assumption that people with CF would have less fatigue because of respiratory improvements from ETI,” Dr. Riekert told this news organization. “Instead, the prevalence of fatigue and poor sleep quality was higher and more chronic than we had anticipated,” she noted.

However, “we were pleasantly surprised that depression and anxiety, while still prevalent, were less prevalent and chronic than previously reported,” Dr. Riekert said in an interview. “We attribute this to the CF Foundation’s mental health initiative that has increased the frequency of annual screening for depression and anxiety and provided resources to help people with cystic fibrosis obtain mental health services,” she said.

The study findings suggest that clinicians should assess people with CF for chronic fatigue and poor sleep along with depression and anxiety and provide treatment or referral, Dr. Riekert said. “For example, cognitive behavioral therapy can effectively treat all the symptoms that were measured in our study,” she noted.

Limitations of the study include the lack of data on how the non-respiratory symptoms interact with respiratory symptoms or pulmonary exacerbations, said Dr. Riekert. “While we assessed these symptoms five times, it was for a year; longer-term follow-up seems merited given our findings,” she said. In addition, “we need to study approaches to make cognitive behavioral therapy and other therapy more accessible for people with cystic fibrosis,” Dr. Riekert said.
 

Targeting Non-Pulmonary Dimensions of CF Care

The current study highlights an aspect of quality of life that is often forgotten when managing adults with CF and may affect their well-being despite effective therapy to improve function and prolong life, said Wissam Chatila, MD, professor of thoracic medicine and surgery at the Lewis Katz School of Medicine at Temple University, Philadelphia, in an interview.

The high incidence of poor sleep, fatigue, depression, and anxiety seen in the current study was “somewhat surprising,” Dr. Chatila said. Also somewhat surprising was the chronicity of the symptoms considering the cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies (designed to correct the malfunctioning protein made by the CFTR gene) that have changed the face of CF, he noted.

However, recent growth in the number of adult patients with CF (more than 50% in certain countries) has led to a change in pathologies that physicians have to manage, and the current study addresses some of the emerging pathologies, said Dr. Chatila.

“Beyond demonstrating survival data from registries and other epidemiologic studies, this study sheds light on the need to address patient-reported outcomes that may or may not be directly related to the pulmonary and GI effects of the CFTR modulators,” he said. “Recognizing the extent of the dysfunction that many CF patients continue to suffer from will eventually lead to identifying factors that contribute to poor outcomes and the mechanisms involved,” he added.

Overall, the current study illustrates the potential benefits of offering personalized medicine to adults with CF that improves not only their physical function but also their mental health, Dr. Chatila said.

The study was funded by the Cystic Fibrosis Foundation. Dr. Riekert had no financial conflicts to disclose. Dr. Chatila had no financial conflicts to disclose.
