Colchicine is an effective treatment for most pediatric patients with complex aphthous stomatitis (CAS), results from a small retrospective study showed.

“Complex aphthous stomatitis in children is typically treated with topical supportive care, which is often not effective,” one of the study investigators, Ananya Shah, a third-year medical student at the University of Rochester School of Medicine & Dentistry, Rochester, New York, told this news organization following the Society for Pediatric Dermatology annual meeting, where the study was presented during a poster session. “There is limited research on CAS and its treatment in children. Colchicine is often used for treatment of CAS in adults, but its use in children has not been studied.”

Ms. Shah, in collaboration with Hilary Kunkel, MD, Nessa Aghazadeh, MD, and Megha Tollefson, MD, of the Department of Dermatology, Mayo Clinic, Rochester, Minnesota, retrospectively reviewed the charts of 20 children diagnosed with CAS who were treated with colchicine, an anti-inflammatory drug often used to treat gout, at the clinic between 2000 and 2023. Treatment responses were defined as no response, partial response, and complete response. Half of the patients were girls, and their median age at presentation was 5 years.

Ulcers were most commonly located in the buccal mucosa (80%), followed by the gingiva (50%), the mucosal lip (50%), and the palate (40%). Nearly all patients (95%) reported that the CAS caused difficulties with eating or drinking. Other effects on their quality of life included weight loss (35%), bleeding (30%), and difficulty brushing teeth (25%). “I was surprised by how much CAS impacts pediatric patients’ quality of life,” Ms. Shah said. “Almost all of the patients experienced trouble with basic activities of daily living, including eating and drinking. In addition, CAS negatively impacted mental health and led to missed school for patients.”

The researchers had follow-up data on responses to colchicine for 14 of the 20 patients. Of these, 12 (86%) had symptom improvement, 5 (36%) had a complete response, 8 (57%) had a partial response, and 1 (7%) did not respond. Nine patients (64%) experienced side effects. Of these, six had diarrhea, two had nausea, and one had constipation.

“Colchicine should be considered as a treatment in pediatric patients who have refractory complex aphthous stomatitis as it is generally well tolerated with minimal side effects,” Ms. Shah said. She acknowledged certain limitations of the study, including its single-center, retrospective design.

The researchers reported having no relevant disclosures.

CHICAGO — Being hormone receptor positive is generally a favorable prognostic factor in breast cancer, but that doesn’t seem to be the case in women with BRCA-associated tumors, according to a study presented at the American Society of Clinical Oncology annual meeting.

The conclusion is based on a large international study on how hormone receptor status impacts breast cancer outcomes in young women with germline BRCA pathological variants (PVs).

Overall, “hormone receptor positivity did not seem to have a strong positive prognostic value in young BRCA carriers” with early breast cancer, lead investigator Luca Arecco, MD, an oncology resident at the University of Genoa, Italy, said at the meeting.

Investigators reviewed the records of 4709 women ages 40 years or younger with stage 1-3 BRCA-associated invasive breast cancer treated from 2000 to 2020 at 78 centers in 28 countries across four continents. Median follow-up was about 8 years.
 

Weaker Prognostic Value in Hormone Receptor Status

They found, in general, that hormone receptor–positive breast cancer appears to be biologically more aggressive in patients with BRCA PVs than in the general breast cancer population, generating outcomes similar to those with hormone receptor-negative BRCA tumors.

Specifically, among patients with germline BRCA PVs, while hormone receptor–positive patients had a higher distant recurrence rate (13.1% vs. 9.6%) than hormone receptor–negative patients, 8-year disease free survival (65.8% and 63.4% respectively) and overall survival (a bit under 90% in both groups) were similar.

Hormone receptor–positive patients did have a lower rate of second primary breast cancers (9.1% versus 14.7%).

In the formal write-up of the results published shortly after the meeting in Annals of Oncology, the investigators concluded that “in young BRCA carriers, differences in recurrence pattern and second primary breast cancer among hormone receptor–positive versus negative disease warrant consideration in counseling patients on treatment, follow-up, and risk-reducing surgery.”

The team also found other differences between BRCA-associated breast cancer and sporadic disease. For instance, in the BRCA cohort, luminal A-like breast cancer had a worse long-term prognosis in their BRCA cohort than triple-negative or HER2-positive disease. Luminal A-like tumors are generally considered less aggressive, but in patients with BRCA PVs, “improving neoadjuvant chemotherapy … could be worthwhile,” the investigators said.

Also, although the risk of recurrence for sporadic hormone receptor–negative tumors is highest in the first few years, the team found that the risk in the hormone negative BRCA cohort progressively increased with longer follow-up, driven by the occurrence of second primary breast cancers, especially in patients with BRCA 1 PVs.
 

Greater Clarity in Prognosis in BRCA-Associated Breast Cancer

Overall, study discussant Lisa A. Carey, MD, a breast cancer specialist at the University of North Carolina at Chapel Hill, said, “we now know much more clearly the issues of prognosis in women who are very young and have germline BRCA-associated breast cancer,” about 12% of newly diagnosed cases.

“Young patients with germline BRCA-associated breast cancers have high relapse and high new primary risks, warranting comprehensive multimodality therapy,” she said.

A bit fewer than half of women in the study were hormone receptor–positive, and they tended to be patients with BRCA 2 PVs. The rest were hormone receptor–negative and tended to have BRCA 1 PVs.

Patients with hormone receptor–positive disease had grade 3 cancers in about 50% of cases, while patients with hormone receptor–negative disease had a grade 3 disease in over 80%.

Hormone receptor–positive patients were more likely to have nodal involvement and undergo mastectomies but less likely to receive chemotherapy than hormone receptor–negative patients. It’s likely that few patients in the review received PARP inhibitors, Dr. Carey noted.

Although overall survival at 8 years was similar in both groups, after that point “the prognosis of patients with hormone receptor–positive disease appeared to be worse … This appeared to occur earlier than that described in sporadic disease,” in which the worsening of survival in hormone receptor–positive disease occurs after a follow-up of at least 14-15 years, the investigators noted in their journal report.

The work was funded by the Italian Association for Cancer Research, Institut Jules Bordet, Korea Health Industry Development Institute, Australian National Health and Medical Council, Cancer Australia, US National Institute of Health, and others. Dr. Arecco had no disclosures. Dr. Carey and other coauthors disclosed research funding, speaker honoraria, and other financial relationships with AstraZeneca, Genentech/Roche, Lilly, and other pharmaceutical companies.

Older adults with relapsed/refractory large B-cell lymphoma (R/R LBCL) treated with CD19-directed chimeric antigen receptor (CAR) T-cell therapy show no significant differences in key survival outcomes versus younger patients, suggesting important benefits for the age group of patients that commonly are diagnosed with this subtype of non-Hodgkin lymphoma.

“This real-world study demonstrates that CD19 CAR-T cell therapy is feasible in a population of patients aged 75 years and older,” said senior author Pierre Bories, MD, PhD, of the Institute for Cancer Strasbourg-Europe, in Alsace, France. He presented the findings at the annual meeting of the European Hematology Association, held in Madrid, Spain.

Patients with R/R LBCL are often older, with many aged over 75, yet patients in those age groups are frequently underrepresented in clinical trials of CD19-directed CAR T-cell therapy, which has significantly improved outcomes for patients with R/R LBCL.

To further investigate differences in outcomes between older and younger patients with R/R LBCL treated with CAR-T cell therapy, Dr. Bories and colleagues conducted a retrospective analysis of 1,524 patients in the French DESCAR-T registry who were treated at treated at 31 centers in France and had at least two previous infusions of CAR-T cell therapy between April 2018 and September 2023.

Of the patients, 69.8% (n = 1065) were treated with axicabtagene ciloleucel (axi-cel), while 30.1% (n = 459) were treated with tisagenlecleucel (tisa-cel).

Among those patients, 125 were 75 years old or older, with a median age of 76, and the remaining 1399 were under the age of 75, with a median age of 62.

The two age groups had significant differences in terms of characteristics including gender, LBCL subset, number of prior lines of therapy, performance status, age-adjusted International Prognostic Index (IPI), rate of patients receiving a bridging therapy, response to the bridging therapy, and LDH at time of infusion.

Compared with patients aged 75 or younger, those who were 75 years or older had a higher hematopoietic cell transplantation–specific comorbidity index (HCT-CI) score, (31.2% high HCT-CI versus 16.8%, respectively; P < .001).

Patients over 75 also had fewer prior transplants than those under 75 (4.8% versus 21.8%, respectively; P < .001), and they more commonly received tisa-cel CAR-T cell therapy (43.2% versus 28.9%, respectively; P < .001).

Among 1457 patients with response data available, with a median follow-up of 12.7 months, there were no significant differences in terms of the best overall response rate (ORR) and complete response rates (CRR) between the two age groups, with rates of 74.8% for ORR and 62.6% for CRR among those 75 or older, compared with 78.0% and 60.8%, respectively, in the under 75 group (P = .425 and P = .699, respectively).

Likewise, the estimated median overall survival (OS) was 18.3 months in the 75 and older group and 24.0 months in the under 75 group (P = .12).

There were also no significant difference in terms of the estimated median progression-free survival, of 8.2 months in the 75 and older group versus 6.1 months in the under 75 group (P = .73).

In terms of safety, there were no significant differences in terms of grade 3 or higher cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) among patients 75 and older versus under 75, with 7.3% versus 7.4% developing CRS, respectively (P = .97), and 9.8% versus 12.4% developing ICANS (P = .39).

There were no significant differences between the age groups regarding ICU admissions, which occurred in about 24% of the cohorts, or the need for mechanical ventilation, which was necessary in about 3% of the entire cohort.

Of note, the overall rates of non-relapse mortality were more common in the 75 years and older group, among whom 19.5% of deaths were not related to lymphoma progression or relapse, compared with 8.1% in the under 75 group (P < .0001).

Early mortalities not related to relapse, defined as occurring before day 28 post-infusion, occurred among 3 patients aged 75 and older (2.4% of all patients 75 and older, representing 12.0% of all non-relapse mortality cases) compared with 16 patients under 75 (1.2% of those patients and 13.1% of all non-relapse mortality).

Infection was the main cause of non-relapse mortality in both groups, representing the cause in 57.7% of those under 75 and 54.2% of those aged 75 and older.

Patients 75 and older had a significantly higher risk of non-relapse mortality from infection (P = .0003), CRS (P = .022) or other causes, compared with those under 75 (P = .0004), but not from ICANS (P = .524).

“Our findings show a higher non-relapse mortality in this older population, which mainly relied on late infectious events, occurring after 28 days,” Dr. Bories said.

“There was also a higher rate of non-relapse mortality from infections, CRS or other causes in those 75 or older, but that did not translate to a lower overall survival in our patient sample,” he said.

Asked at the session about the implications of the higher infection risk in elderly patients, Dr. Bories said, “I think this deserves special attention and we have to be more careful with frail patients.

“This should obviously encourage the use of prophylaxis for a longer period of time.”

Dr. Bories noted that he and his team are currently conducting a more detailed propensity-matched comparison between axi-cel and tisa-cel in an older population.

The findings are consistent with those of other studies, among the latest including a 2024 real-world multicenter study of 172 diffuse LBCL (DLBCL) patients treated with CAR-T cell therapy (mostly axi-cel).

That study showed comparable median progression-free and OS rates between those over and under the age of 70, however, in contrast to the current study, that study showed no significant differences in non-relapse mortality.

The ORR in that study also did not differ between age groups, exceeding 75%.

Of note, in that study, tisa‐cel treatment was associated with an approximately 60% higher risk of relapse and/or death compared with axi‐cel treatment, which the authors report was driven primarily by less favorable survival outcomes among tisa‐cel patients younger than age 70 years.

“In this context, some reports showed that axi‐cel may offer enhanced effectiveness compared to tisa‐cel in patients aged 65 and older, despite higher rates of neurotoxicity,” they wrote.

Nevertheless, the study’s overall findings indicate that “CAR T-cell therapy should be not withheld for elderly patients with r/r DLBCL,” the authors concluded.
 

Low CAR T Utilization in Elderly Patients

Overall, utilization of CAR-T cell therapy among older patients reportedly remains low, as demonstrated in one recent real-world study on the issue, involving 551 older patients with DLBCL.

The study showed that 19% of patients aged 65-69 and 22% of those aged 70-74 years received CAR-T cell therapy, compared with only 13% of those aged 75 and older.

“While CAR T-cell therapy in older patients is associated with favorable event-free survival comparable to outcomes in younger patients, CAR T-cell usage is low in older patients with DLBCL, which suggests an unmet need for more accessible, effective, and tolerable therapy,” reported first author Dia Chihara, MD, PhD, of the Department of Lymphoma and Myeloma, The University of Texas MD Anderson Cancer Center, in Houston, Texas, and colleagues.

Noting that “the use of current CAR-T cell therapy products seemed to be limited to selected patients,” the authors added that “this may change in the future with next-generation CAR T-cell therapy products.”

Dr. Bories disclosed relationships with Kite Gilead, Novartis, BMD-Celgene, Abbvie, Servier, Janssen and the BMS foundation.

Early mortalities not related to relapse, defined as occurring before day 28 post-infusion, occurred among 3 patients aged 75 and older (2.4% of all patients 75 and older, representing 12.0% of all non-relapse mortality cases) compared with 16 patients under 75 (1.2% of those patients and 13.1% of all non-relapse mortality).

Infection was the main cause of non-relapse mortality in both groups, representing the cause in 57.7% of those under 75 and 54.2% of those aged 75 and older.

Patients 75 and older had a significantly higher risk of non-relapse mortality from infection (P = .0003), CRS (P = .022) or other causes, compared with those under 75 (P = .0004), but not from ICANS (P = .524).

“Our findings show a higher non-relapse mortality in this older population, which mainly relied on late infectious events, occurring after 28 days,” Dr. Bories said.

“There was also a higher rate of non-relapse mortality from infections, CRS or other causes in those 75 or older, but that did not translate to a lower overall survival in our patient sample,” he said.

Asked at the session about the implications of the higher infection risk in elderly patients, Dr. Bories said, “I think this deserves special attention and we have to be more careful with frail patients.

“This should obviously encourage the use of prophylaxis for a longer period of time.”

Dr. Bories noted that he and his team are currently conducting a more detailed propensity-matched comparison between axi-cel and tisa-cel in an older population.

The findings are consistent with those of other studies, among the latest including a 2024 real-world multicenter study of 172 diffuse LBCL (DLBCL) patients treated with CAR-T cell therapy (mostly axi-cel).

That study showed comparable median progression-free and OS rates between those over and under the age of 70, however, in contrast to the current study, that study showed no significant differences in non-relapse mortality.

The ORR in that study also did not differ between age groups, exceeding 75%.

Of note, in that study, tisa‐cel treatment was associated with an approximately 60% higher risk of relapse and/or death compared with axi‐cel treatment, which the authors report was driven primarily by less favorable survival outcomes among tisa‐cel patients younger than age 70 years.

“In this context, some reports showed that axi‐cel may offer enhanced effectiveness compared to tisa‐cel in patients aged 65 and older, despite higher rates of neurotoxicity,” they wrote.

Nevertheless, the study’s overall findings indicate that “CAR T-cell therapy should be not withheld for elderly patients with r/r DLBCL,” the authors concluded.
 

Low CAR T Utilization in Elderly Patients

Overall, utilization of CAR-T cell therapy among older patients reportedly remains low, as demonstrated in one recent real-world study on the issue, involving 551 older patients with DLBCL.

The study showed that 19% of patients aged 65-69 and 22% of those aged 70-74 years received CAR-T cell therapy, compared with only 13% of those aged 75 and older.

“While CAR T-cell therapy in older patients is associated with favorable event-free survival comparable to outcomes in younger patients, CAR T-cell usage is low in older patients with DLBCL, which suggests an unmet need for more accessible, effective, and tolerable therapy,” reported first author Dia Chihara, MD, PhD, of the Department of Lymphoma and Myeloma, The University of Texas MD Anderson Cancer Center, in Houston, Texas, and colleagues.

Noting that “the use of current CAR-T cell therapy products seemed to be limited to selected patients,” the authors added that “this may change in the future with next-generation CAR T-cell therapy products.”

Older adults with relapsed/refractory large B-cell lymphoma (R/R LBCL) treated with CD19-directed chimeric antigen receptor (CAR) T-cell therapy show no significant differences in key survival outcomes versus younger patients, suggesting important benefits for the age group of patients that commonly are diagnosed with this subtype of non-Hodgkin lymphoma.

“This real-world study demonstrates that CD19 CAR-T cell therapy is feasible in a population of patients aged 75 years and older,” said senior author Pierre Bories, MD, PhD, of the Institute for Cancer Strasbourg-Europe, in Alsace, France. He presented the findings at the annual meeting of the European Hematology Association, held in Madrid, Spain.

Patients with R/R LBCL are often older, with many aged over 75, yet patients in those age groups are frequently underrepresented in clinical trials of CD19-directed CAR T-cell therapy, which has significantly improved outcomes for patients with R/R LBCL.

To further investigate differences in outcomes between older and younger patients with R/R LBCL treated with CAR-T cell therapy, Dr. Bories and colleagues conducted a retrospective analysis of 1,524 patients in the French DESCAR-T registry who were treated at treated at 31 centers in France and had at least two previous infusions of CAR-T cell therapy between April 2018 and September 2023.

Of the patients, 69.8% (n = 1065) were treated with axicabtagene ciloleucel (axi-cel), while 30.1% (n = 459) were treated with tisagenlecleucel (tisa-cel).

Among those patients, 125 were 75 years old or older, with a median age of 76, and the remaining 1399 were under the age of 75, with a median age of 62.

The two age groups had significant differences in terms of characteristics including gender, LBCL subset, number of prior lines of therapy, performance status, age-adjusted International Prognostic Index (IPI), rate of patients receiving a bridging therapy, response to the bridging therapy, and LDH at time of infusion.

Compared with patients aged 75 or younger, those who were 75 years or older had a higher hematopoietic cell transplantation–specific comorbidity index (HCT-CI) score, (31.2% high HCT-CI versus 16.8%, respectively; P < .001).

Patients over 75 also had fewer prior transplants than those under 75 (4.8% versus 21.8%, respectively; P < .001), and they more commonly received tisa-cel CAR-T cell therapy (43.2% versus 28.9%, respectively; P < .001).

Among 1457 patients with response data available, with a median follow-up of 12.7 months, there were no significant differences in terms of the best overall response rate (ORR) and complete response rates (CRR) between the two age groups, with rates of 74.8% for ORR and 62.6% for CRR among those 75 or older, compared with 78.0% and 60.8%, respectively, in the under 75 group (P = .425 and P = .699, respectively).

Likewise, the estimated median overall survival (OS) was 18.3 months in the 75 and older group and 24.0 months in the under 75 group (P = .12).

There were also no significant difference in terms of the estimated median progression-free survival, of 8.2 months in the 75 and older group versus 6.1 months in the under 75 group (P = .73).

In terms of safety, there were no significant differences in terms of grade 3 or higher cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) among patients 75 and older versus under 75, with 7.3% versus 7.4% developing CRS, respectively (P = .97), and 9.8% versus 12.4% developing ICANS (P = .39).

There were no significant differences between the age groups regarding ICU admissions, which occurred in about 24% of the cohorts, or the need for mechanical ventilation, which was necessary in about 3% of the entire cohort.

Of note, the overall rates of non-relapse mortality were more common in the 75 years and older group, among whom 19.5% of deaths were not related to lymphoma progression or relapse, compared with 8.1% in the under 75 group (P < .0001).

Black metastatic breast cancer patients with PIK3CA mutations were less likely to receive targeted therapy and less likely to be enrolled in clinical trials than White patients and had shorter overall survival, according to a retrospective cohort study. Black and White patients were equally likely to receive other drugs that did not require genomic testing.

“These clinical inequities in the use of targeted therapies and clinical trials ... must be a focus going forward,” said lead investigator Emily Podany, MD, a clinical fellow in hematology-oncology at Washington University in St. Louis, Missouri. “Our consortium is looking for paths forward in order to try and decrease these striking inequities. And it’s a focus of future research for us and future implementation [of] science interventions, hopefully, across the country.”

The study results were presented at the annual meeting of the American Society of Clinical Oncology.
 

Black Women Underrepresented

Black women are generally underrepresented in clinical trials, noted Dr. Podany. “They make up about 2%-5% of the patients in breast cancer clinical trials, and there are documented inequities in treatment and in outcomes for Black patients with metastatic breast cancer. This includes longer treatment delays, it includes fewer sentinel lymph node biopsies, and unfortunately, they’re more likely to discontinue treatment early.”

In terms of PI3K inhibition, PIK3CA mutations are found in about 40% of patients with HR-positive HER2-negative metastatic breast cancer. Alpelisib is FDA-approved as a targeted therapy for these patients, she said.

The study evaluated records of 1327 patients with metastatic breast cancer who also had circulating tumor DNA (ctDNA) results and were treated at Washington University, Massachusetts General Hospital in Boston, and Northwestern University in Chicago. Of these, 795 had an ER-positive, HER2-negative subtype and were included in the analysis. Most (89%) of the patients were White (n = 708), while 11% (n = 87) were Black, and the only baseline difference between patients was that Black patients had significantly more de novo metastatic breast cancer (31% versus 22%).

Use of PI3K, CDK4/6, or mTOR inhibitors was evaluated using manual electronic medical review, and genomic differences were evaluated using logistic regression.

The analysis showed inequities in both treatment and clinical trial enrollment. There were no differences between groups in the use of CDK4/6 or mTOR inhibitors, which do not require a genomic profile, the researchers noted, but Black patients with PIK3CA single nucleotide variants (SNV) were significantly less likely than White patients to use PI3K inhibitors (5.9% versus 28.8%; P = .045), despite no difference in PIK3CA mutations between groups (36% and 34% respectively). Similarly, 11% of White patients with PIK3CA mutations were enrolled in clinical trials, but none of the Black patients was.

Genomic differences were also found, Dr. Podany reported. Black patients with estrogen/progesterone receptor (ER/PR) positive, HER2-negative disease were more likely to have a CCND1 copy number variant. And for ER-positive PR-negative HER2-negative patients, Black patients were more likely to have a GATA3 SNV, while White patients were more likely to have a KRAS copy number variant.
 

Black Survival Less Than Half

The analysis also found significant differences in overall survival from the time of the first liquid biopsy, with White ER-positive, PR-negative, HER2-negative patients living a median of 21 months, versus 9.1 months for Black patients.

There were several limitations to the study beyond its retrospective nature, “so, we may be underestimating the true inequity,” noted Dr. Podany. “These are large urban academic centers, so our patients have access to these treatments. They have access to care. They have access to ctDNA liquid biopsy testing. And the timing of ctDNA, especially the first ctDNA test, is variable and provider-dependant. We were also unable to assess receipt of PI3 kinase inhibitors at future time points after the end of this cohort study.”

Asked for comment, Giuseppe Del Priore, MD, MPH, from Morehouse School of Medicine in Atlanta, Georgia, approved of the study design “with subjects limited to three distinctive institutions. That parameter alone can control for several unknown variables among the studied comparison groups, ie, Black women versus others.”

However, Dr. Del Priore, who is adjunct professor of obstetrics and gynecology, with a specialty in oncology, added, “retrospective studies are not reliable except for generating hypotheses. Therefore, I would like to see a rapid implementation of an intervention trial at these same institutions to ensure equal consideration of, and access to, targeted therapies. Too often a retrospective correlation is reported, but the solution is elusive due to unknown factors. In this case, knowing there is a mutation is far from alleviating the disproportionate burden of disease that many communities face.”

Dr. Podany had no relevant disclosures. Dr. Del Priore reported no conflicts of interest and disclosed that he is chief medical officer at BriaCell.

Twice-yearly injections are 100% effective in preventing new infections, according to the final results from the PURPOSE 1 trial of lenacapavir.

For weeks, the HIV community has been talking about this highly anticipated clinical trial and whether the strong — and to many, surprising — interim results would hold at final presentation at the International AIDS Conference 2024 in Munich, Germany.

Presenting the results, Linda-Gail Bekker, MD, director of the Desmond Tutu HIV Center at the University of Cape Town, South Africa, reported zero new infections in those who got the shots in the study of about 5000 young women. In the group given daily oral preexposure prophylaxis (PrEP), roughly 2% contracted HIV from infected partners.

“A twice-yearly PrEP choice could overcome some of the adherence and persistence challenges and contribute critically to our quest to reduce HIV infection in women around the world,” Dr. Bekker said about the results, which were published simultaneously in The New England Journal of Medicine.

PURPOSE 1 confirmed that lenacapavir is a “breakthrough” for HIV prevention, said International AIDS Society president Sharon Lewin, PhD, MBBS. It has “huge public health potential,” said Dr. Lewin, the AIDS 2024 conference cochair and director of the Peter Doherty Institute for Infection and Immunity at the University of Melbourne in Australia.

Lenacapavir is a novel, first-in-class multistage HIV-1 capsid inhibitor with a long half-life, which enables the twice-yearly dosing.

PURPOSE 1 enrolled women aged 15-25 years who were at risk for HIV in South Africa and Uganda, with a primary endpoint of HIV infection. Because of the previously announced interim results, which showed the injection was preventing infections, study sponsor Gilead Sciences discontinued the randomized phase of the trial and shifted to an open-label design for lenacapavir.

“One hundred percent efficacy is more that we could ever have hoped for a potential prevention efficacy,” said Christoph Spinner, MD, MBA, an infectious disease specialist at the University Hospital of the Technical University of Munich and AIDS 2024 conference cochair.

Dr. Spinner added that while this is the first study of lenacapavir for PrEP, it’s also the first to explore outcomes of emtricitabine-tenofovir in cisgender women.
 

Strong Adherence Rates

The twice-yearly injection demonstrated adherence rates above 90% in the trial for both the 6- and 12-month injection intervals.

“Adherence was 91.5% at week 26 and 92.8% at week 52,” Dr. Bekker reported. 

The trial compared three PrEP options including the lenacapavir injection to once-daily oral emtricitabine 200 mg and tenofovir-alafenamide 25 mg (F/TAF) and once-daily emtricitabine 200 mg and tenofovir–disoproxil fumarate 300 mg (F/TDF).

“Most participants in both the F/TAF and F/TDF groups had low adherence, and this declined over time,” Dr. Bekker reported. At 52 weeks, the vast majority of patients on both oral therapies had low adherence with dosing, defined at less than two doses a week.

Dr. Bekker called the adherence to the oral agents in this trial “disappointing.”

Findings from the trial underscore the challenges of adherence to a daily oral medication, Rochelle Walensky, MD, and Lindsey Baden, MD, from the Harvard Kennedy School of Government and Harvard Business School in Cambridge, Massachusetts, wrote in an editorial accompanying the published results.

With almost 92% attendance for the twice-yearly lenacapavir injections, the “well-done,” large, randomized, controlled trial “exemplifies not only that women can dependably adhere to this administration schedule, but also that levels of an HIV-1 capsid inhibitor can remain high enough over a period of 6 months to reliably prevent infection,” they added. 

Another key focus of the presentation was adverse events. The rate of adverse events grade 3 or more in the lenacapavir arm was 4.1%, Bekker said, which is slightly lower than the rates in the oral arms. The rates of serious adverse events were 2.8% for lenacapavir, 4% for F/TAF and 3.3% for F/TDF. 
 

Injection Site Reactions

Injection site reactions occurred in 68% of the lenacapavir group, including 63% with subcutaneous nodules.

The injection can form “a drug depot which may be palpable as a nodule,” Dr. Bekker said. In the placebo group, 34% of patients had injection-site reactions and 16% had nodules. Nearly all injection-site reactions were grade 1 or 2, she said. “Higher grade injection-site reactions were rare and not serious and occurred in a similar percentage in lenacapavir and placebo,” she said.

Overall, more than 25,000 injections of lenacapavir have been given, Dr. Bekker said, and four patients discontinued treatment because of injection-site reactions. “Reporting of injection-site reactions, including nodules, decreased with subsequent doses,” she said.

Contraception was not a requirement for enrollment in the study, Dr. Bekker pointed out, and pregnancy outcomes across the treatment arms were similar to the general population.
 

First in a Series of Trials

This is the first in a series of PURPOSE trials, Bekker reported. The phase 3 PURPOSE 2 trial, enrolling 3000 gay men, transgender women, transgender men and gender nonbinary people who have sex with male partners, is the second pivotal trial now underway.

Three other smaller trials are in the clinic in the United States and Europe.

PURPOSE 1 participants will continue to access lenacapavir until the product is available in South Africa and Uganda, Dr. Bekker said. Trial sponsor Gilead Sciences is also developing a direct licensing program to expedite generic access to the drug in high-incidence, resource-limited countries, she said.

Dr. Walensky and Dr. Baden report that lenacapavir currently costs about $43,000 annually in the United States. “But the results of the PURPOSE 1 trial have now created a moral imperative to make lenacapavir broadly accessible and affordable as PrEP” to people who were enrolled, as well as all those who are similarly eligible and could benefit.

So now we have a PrEP product with high efficacy, they added. “That is great news for science but not (yet) great for women.” 

Given the high pregnancy rate among participants in the PURPOSE 1 trial, Dr. Walensky and Dr. Baden point out the assessment of lenacapavir safety is a priority. They are also interested in learning more about drug resistance with this new option. 

“I f approved and delivered — rapidly, affordably, and equitably — to those who need or want it, this long-acting tool could help accelerate global progress in HIV prevention,” Dr. Lewin said.

Twice-yearly injections are 100% effective in preventing new infections, according to the final results from the PURPOSE 1 trial of lenacapavir.

For weeks, the HIV community has been talking about this highly anticipated clinical trial and whether the strong — and to many, surprising — interim results would hold at final presentation at the International AIDS Conference 2024 in Munich, Germany.

Presenting the results, Linda-Gail Bekker, MD, director of the Desmond Tutu HIV Center at the University of Cape Town, South Africa, reported zero new infections in those who got the shots in the study of about 5000 young women. In the group given daily oral preexposure prophylaxis (PrEP), roughly 2% contracted HIV from infected partners.

“A twice-yearly PrEP choice could overcome some of the adherence and persistence challenges and contribute critically to our quest to reduce HIV infection in women around the world,” Dr. Bekker said about the results, which were published simultaneously in The New England Journal of Medicine.

PURPOSE 1 confirmed that lenacapavir is a “breakthrough” for HIV prevention, said International AIDS Society president Sharon Lewin, PhD, MBBS. It has “huge public health potential,” said Dr. Lewin, the AIDS 2024 conference cochair and director of the Peter Doherty Institute for Infection and Immunity at the University of Melbourne in Australia.

Lenacapavir is a novel, first-in-class multistage HIV-1 capsid inhibitor with a long half-life, which enables the twice-yearly dosing.

PURPOSE 1 enrolled women aged 15-25 years who were at risk for HIV in South Africa and Uganda, with a primary endpoint of HIV infection. Because of the previously announced interim results, which showed the injection was preventing infections, study sponsor Gilead Sciences discontinued the randomized phase of the trial and shifted to an open-label design for lenacapavir.

“One hundred percent efficacy is more that we could ever have hoped for a potential prevention efficacy,” said Christoph Spinner, MD, MBA, an infectious disease specialist at the University Hospital of the Technical University of Munich and AIDS 2024 conference cochair.

Dr. Spinner added that while this is the first study of lenacapavir for PrEP, it’s also the first to explore outcomes of emtricitabine-tenofovir in cisgender women.
 

Strong Adherence Rates

The twice-yearly injection demonstrated adherence rates above 90% in the trial for both the 6- and 12-month injection intervals.

“Adherence was 91.5% at week 26 and 92.8% at week 52,” Dr. Bekker reported. 

The trial compared three PrEP options including the lenacapavir injection to once-daily oral emtricitabine 200 mg and tenofovir-alafenamide 25 mg (F/TAF) and once-daily emtricitabine 200 mg and tenofovir–disoproxil fumarate 300 mg (F/TDF).

“Most participants in both the F/TAF and F/TDF groups had low adherence, and this declined over time,” Dr. Bekker reported. At 52 weeks, the vast majority of patients on both oral therapies had low adherence with dosing, defined at less than two doses a week.

Dr. Bekker called the adherence to the oral agents in this trial “disappointing.”

Findings from the trial underscore the challenges of adherence to a daily oral medication, Rochelle Walensky, MD, and Lindsey Baden, MD, from the Harvard Kennedy School of Government and Harvard Business School in Cambridge, Massachusetts, wrote in an editorial accompanying the published results.

With almost 92% attendance for the twice-yearly lenacapavir injections, the “well-done,” large, randomized, controlled trial “exemplifies not only that women can dependably adhere to this administration schedule, but also that levels of an HIV-1 capsid inhibitor can remain high enough over a period of 6 months to reliably prevent infection,” they added. 

Another key focus of the presentation was adverse events. The rate of adverse events grade 3 or more in the lenacapavir arm was 4.1%, Bekker said, which is slightly lower than the rates in the oral arms. The rates of serious adverse events were 2.8% for lenacapavir, 4% for F/TAF and 3.3% for F/TDF. 
 

Injection Site Reactions

Injection site reactions occurred in 68% of the lenacapavir group, including 63% with subcutaneous nodules.

The injection can form “a drug depot which may be palpable as a nodule,” Dr. Bekker said. In the placebo group, 34% of patients had injection-site reactions and 16% had nodules. Nearly all injection-site reactions were grade 1 or 2, she said. “Higher grade injection-site reactions were rare and not serious and occurred in a similar percentage in lenacapavir and placebo,” she said.

Overall, more than 25,000 injections of lenacapavir have been given, Dr. Bekker said, and four patients discontinued treatment because of injection-site reactions. “Reporting of injection-site reactions, including nodules, decreased with subsequent doses,” she said.

Contraception was not a requirement for enrollment in the study, Dr. Bekker pointed out, and pregnancy outcomes across the treatment arms were similar to the general population.
 

First in a Series of Trials

This is the first in a series of PURPOSE trials, Bekker reported. The phase 3 PURPOSE 2 trial, enrolling 3000 gay men, transgender women, transgender men and gender nonbinary people who have sex with male partners, is the second pivotal trial now underway.

Three other smaller trials are in the clinic in the United States and Europe.

PURPOSE 1 participants will continue to access lenacapavir until the product is available in South Africa and Uganda, Dr. Bekker said. Trial sponsor Gilead Sciences is also developing a direct licensing program to expedite generic access to the drug in high-incidence, resource-limited countries, she said.

Dr. Walensky and Dr. Baden report that lenacapavir currently costs about $43,000 annually in the United States. “But the results of the PURPOSE 1 trial have now created a moral imperative to make lenacapavir broadly accessible and affordable as PrEP” to people who were enrolled, as well as all those who are similarly eligible and could benefit.

So now we have a PrEP product with high efficacy, they added. “That is great news for science but not (yet) great for women.” 

Given the high pregnancy rate among participants in the PURPOSE 1 trial, Dr. Walensky and Dr. Baden point out the assessment of lenacapavir safety is a priority. They are also interested in learning more about drug resistance with this new option. 

“I f approved and delivered — rapidly, affordably, and equitably — to those who need or want it, this long-acting tool could help accelerate global progress in HIV prevention,” Dr. Lewin said.

Now, she added, “we eagerly await results from PURPOSE 2.”

TOPLINE:

More gastrointestinal and nervous symptom adverse events (AEs) are linked to apremilast than deucravacitinib, which is associated with more cutaneous AEs, according to a retrospective comparison using US Food and Drug Administration (FDA) data.

METHODOLOGY:

• To evaluate the adverse events associated with apremilast, an oral phosphodiesterase-4 (PDE4) inhibitor, and deucravacitinib, an oral tyrosine kinase 2 (TYK2) inhibitor, data were drawn from the FDA’s Adverse Event Reporting System database.
• The Medex_UIMA_1.8.3 system was used to standardize drug names, and MedDRA terminology was used to encode, categorize, and localize signals.
• AE event signals were grouped by skin and subcutaneous tissue disorders, gastrointestinal disorders, infections and infestations, and nervous system disorders.

TAKEAWAY:

• There were 95,734 AE reports for apremilast and 760 AE reports for deucravacitinib, and AEs were found to be significant over time.
• The more common cutaneous AEs were psoriasis recurrence and acne (associated with apremilast) and skin burning and erythema (associated with deucravacitinib).
• The more common gastrointestinal AEs were diarrhea and nausea (apremilast) and mouth ulceration (deucravacitinib).
• Deucravacitinib-related pruritus and rash, as well as apremilast-related tension headache, were more common in women than men; deucravacitinib-related skin burning was more common in men.

IN PRACTICE:

The results “can help the doctors to choose the right treatment options based on the baseline characteristics of different patients,” said Yuanyuan Xu, a graduate student in the Department of Dermatology, Sichuan University, Chengdu, China.

SOURCE:

Mr. Xu presented the study as a poster at the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis 2024 annual meeting.

LIMITATIONS:

The study was retrospective and cannot prove causality, and there were far fewer AE reports related to deucravacitinib, likely because the drug was introduced more recently.

DISCLOSURES:

The study received no funding, and the authors had no relevant financial disclosures.

TOPLINE:

Rates of major adverse cardiovascular events (MACE) do not differ significantly among individual biologics used for psoriasis or psoriatic arthritis (PsA), a database analysis finds. 

METHODOLOGY:

• Data from the TriNetX health records database included 32,758 patients treated with TNF inhibitors (TNFi, 62.9%), interleukin-17 inhibitors (IL-17i, 15.4%), IL-23i (10.7%), and IL-12i/IL-23i (10.7%).
• The researchers calculated time-dependent risk for MACE using multinomial Cox proportional hazard ratios. The reference was TNFi exposure.
• Subset analyses compared MACE in patients with and without existing cardiovascular disease.

TAKEAWAY:

• Compared with TNFi use, there was no difference in the incidence of MACE events in the IL-17i, IL-23i, or IL-12i/IL-23i group.
• There were also no significant differences between biologic groups in the incidence of congestive heart failure, myocardial infarction, or cerebral vascular accident/stroke.

IN PRACTICE:

Despite some concern about increased risk for MACE with TNFi use, this study suggests no special risk for patients with psoriasis or PsA associated with TNFi vs other biologics. “Given our results, as it pertains to MACE, prescribers shouldn’t favor any one biologic class over another,” said lead investigator Shikha Singla, MD, medical director of the Psoriatic Arthritis Program at Medical College of Wisconsin in Milwaukee, Wisconsin.

SOURCE:

Bonit Gill, MD, a second-year fellow at Medical College of Wisconsin, presented the study as a poster at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis. 

LIMITATIONS:

The study’s retrospective nature makes it impossible to prove causation and the patients included in the study were from Wisconsin, which may limit generalizability.

DISCLOSURES:

Dr. Gill had no relevant financial disclosures. Other study authors participated in trials or consulted for AbbVie, AstraZeneca, Novartis, Eli Lilly, Janssen, and UCB.

Now, 75 years after the first presentations were made on the “sensational” effects of cortisone in the treatment of rheumatoid arthritis (RA), glucocorticoids (GCs) are still highly relevant and widely used in the management of RA and other immune-mediated inflammatory diseases.

“It makes me smile because this is such an old drug, and we need it still so much. It still hasn’t been replaced,” Josef S. Smolen, MD, observed at annual European Congress of Rheumatology.

At low doses, GCs are highly effective as anti-inflammatory and anti-destructive agents in RA and many other diseases, said Dr. Smolen, a rheumatologist and immunologist and professor emeritus at the Medical University of Vienna, Austria.

But even after all this time, the mechanisms that lead to efficacy vs toxicity have yet to be clarified. “Such separation may provide further insights into future treatment options,” said Dr. Smolen.

Sara Freeman/MDedge News

Societies Agree: Discontinue as Fast as Possible

GCs have been associated with a long list of adverse events, most notably Cushing syndrome, hypertension, cardiovascular disease, osteoporosis, myopathy, peptic ulcer, adrenal insufficiency (AI), infections, mood disorders, ophthalmologic disorders such as cataracts, skin disorders, menstrual septic necrosis, and pancreatitis.

Dose matters, Dr. Smolen said, citing studies that found that cumulative GC doses of 1000 or 1100 mg increase risks. One study by German researchers found that doses above 10 mg/d significantly raised the hazard ratio for death.

Because high disease activity is also associated with an equally high mortality risk, “we have to balance this out: Active disease vs glucocorticoid use, especially in countries that have less access to modern therapies than we have in the more affluent Western regions,” Dr. Smolen said.

Rheumatology societies generally agree that clinicians should try to minimize GC use or eventually discontinue the therapy.

The American College of Rheumatology recommends not using GCs as part of the first-line treatment of RA. “And if you want to use [them], you should do that for less than 3 months, taper and discontinue as fast as possible, and use the lowest dose possible,” Dr. Adami said.

EULAR’s recommendation is more nuanced in that it allows for a lower dose but gives physicians more choice in how they want to handle GCs, Dr. Adami said. The task force added that all patients should try to taper down or discontinue as fast as possible, he said.

For GCs in the management of systemic lupus erythematosus, a EULAR task force recommended that the type and severity of organ involvement should determine dose, with a long-term goal of maintaining the dose < 5 mg/d or possibly withdrawing it.

EULAR also recommends GC bridging when initiating or changing conventional synthetic (cs) DMARDs. This effectively dismisses the use of GCs when using biologic DMARDs or targeted synthetic DMARDs. As a bridging therapy, EULAR recommends either a single parenteral dose of GC or a predefined tapering or discontinuation scheme within 3 months, when starting an oral GC.
 

Low-Dose Approach Gains Ground

While saying he’d be the first physician to eliminate GCs whenever possible, Dr. Buttgereit made the case before the EULAR Congress that GCs in low doses could still play a role in treatment.

Many physicians believe that very low doses between 2 and 4 mg/d are a realistic therapy option for RA, he said, adding that a mean daily usage < 5 mg could be used over a longer period with relatively low risk.

Several studies he coauthored tested the 5-mg approach. The GLORIA trial compared 5 mg/d prednisolone and placebo in 451 patients aged 65 years and older with active RA over the course of 2 years. The researchers found that patients on prednisolone had a mean Disease Activity Score in 28 joints (DAS28) that was 0.37 points lower and mean joint damage score that was 1.7 points lower than those of patients on placebo, suggesting that the GC had long-term benefits in these patients with RA.

The tradeoff was a 24% increase in the risk of having at least one adverse event of special interest, but most of these events were non-severe infections, Dr. Buttgereit said.

Another study, the SEMIRA trial, assigned 128 patients to a continued regimen of prednisone 5 mg/d for 24 weeks. Another group of 131 patients received a tapered-prednisone regimen. All patients received tocilizumab 162 mg with or without csDMARDs, maintained at stable doses.

Patients in the first cohort achieved superior disease activity control than those in the tapered regimen group. “The side effects showed that in the tapering prednisone group, there were more treatment-emergent adverse effects in this double-blind trial as compared to the continued prednisone group,” Dr. Buttgereit said.

One limitation of the SEMIRA trial was that it studied the effect of tocilizumab as a GC-sparing agent, and it didn’t consider using a tumor necrosis factor or Janus kinase (JAK) inhibitor, which might have a more potent effect on pain and GC dose reduction, Dr. Adami said. “Why do we need to use glucocorticoids if we know they might be detrimental, if we know there might be some other option in our armamentarium?”

Other studies have shown that low-dose GC protocols can be used with standard treatment, according to Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh School of Medicine.

“Examples of this are the LoVAS and PEXIVAS studies for antineutrophil cytoplasmic antibody-associated [ANCA] vasculitis. This has been highlighted in existing treatment recommendations for ANCA vasculitis and systemic lupus erythematosus nephritis,” Dr. Sattui said.

Debating the Toxicity Threshold

Are low GC dosages significantly associated with adverse events like mortality, cardiovascular, or diabetes risk? It depends on who you ask.

Much of the toxicity data on GCs come from inadequately powered or controlled studies and often refer to doses that currently are considered too high, Dr. Buttgereit said. His presentation highlighted a study from Hong Kong, a time-varying analysis of GC dose and incident risk for major adverse cardiovascular events (MACE) in more than 12,000 patients with RA. Researchers found that GC regimens ≥ 5 mg/d significantly increased the risk for MACE. Comparatively, doses below this threshold did not confer excessive risk, he said.

Low-dose GCs are lesser toxic than high-dose GCs, noted Joan Merrill, MD, a professor with the Arthritis and Clinical Immunology Research Program at The University of Oklahoma Health Sciences Center, Oklahoma City. “There may be less weight gain, less chance of acne, and less risk for all the slower, more organ-threatening side effects.”

Bianca Nogrady/MDedge News

Tapering Options Across Diseases

Rheumatologists in the field continue to navigate GC-tapering options and treatment combinations that reduce the cumulative use of GCs over time, finding their own solutions based on the conditions they treat.

In his EULAR presentation, Dr. Buttgereit suggested that current therapeutic approaches for RA may be too narrow when they don’t consider the possibility of including very low doses of GCs.

For RA, “why shouldn’t we not do a combination of something like methotrexate plus a JAK inhibitor or a biological,” plus a very low dose of GCs < 5 mg/d, he asked.

However, Dr. Adami said he generally avoids GCs if RA disease activity is not severe (based on DAS28) and if the patient has a visual analog scale pain score < 7. “Nonetheless, even in patients with more severe disease, I would avoid GCs for more than 3 months. Usually, 1 month of steroids, tapered rapidly and discontinued.”

All patients should receive an appropriate treat-to-target strategy with csDMARDs and biologics if needed, he added.

A patient coming to clinic with difficult-to-treat RA who chronically uses GCs deserves special attention. The priority is bone protection with an anti-osteoporosis medication. “I found that JAK inhibitors, in some cases, help with the discontinuation of steroids, especially in those with residual pain. Therefore, I would think of switching medication,” Dr. Adami said.

For polymyalgia rheumatica, most clinicians will likely try to taper GCs around 52 weeks, similar to ACR/EULAR guidelines, according to Robert F. Spiera, MD, director of the Scleroderma and Vasculitis Program at Hospital for Special Surgery, New York City.

What to Consider for AI Symptoms

Clinicians also need to address AI in patients who are coming off GCs, Dr. Sattui said. He advised that symptoms suggestive of AI, including malaise, fatigue, nausea, and muscle and/or joint pain, should guide testing.

Even in the absence of symptoms, clinicians should consider assessing patients who have been on high doses for prolonged periods or obese or older adults who might be at a high risk for AI. “Signs to consider include weight loss, hypotension, or orthostatism,” he said.

Differentiating between AI symptoms and symptoms from the underlying disease can be a challenge. This requires a physical exam and workup, including morning serum cortisol. Collaboration with endocrinology colleagues and other treating providers is important, as well as patient education of symptoms and monitoring for possible adjustments in treating AI and other acute diseases, he said.

Now, 75 years after the first presentations were made on the “sensational” effects of cortisone in the treatment of rheumatoid arthritis (RA), glucocorticoids (GCs) are still highly relevant and widely used in the management of RA and other immune-mediated inflammatory diseases.

“It makes me smile because this is such an old drug, and we need it still so much. It still hasn’t been replaced,” Josef S. Smolen, MD, observed at annual European Congress of Rheumatology.

At low doses, GCs are highly effective as anti-inflammatory and anti-destructive agents in RA and many other diseases, said Dr. Smolen, a rheumatologist and immunologist and professor emeritus at the Medical University of Vienna, Austria.

But even after all this time, the mechanisms that lead to efficacy vs toxicity have yet to be clarified. “Such separation may provide further insights into future treatment options,” said Dr. Smolen.

Societies Agree: Discontinue as Fast as Possible

GCs have been associated with a long list of adverse events, most notably Cushing syndrome, hypertension, cardiovascular disease, osteoporosis, myopathy, peptic ulcer, adrenal insufficiency (AI), infections, mood disorders, ophthalmologic disorders such as cataracts, skin disorders, menstrual septic necrosis, and pancreatitis.

Dose matters, Dr. Smolen said, citing studies that found that cumulative GC doses of 1000 or 1100 mg increase risks. One study by German researchers found that doses above 10 mg/d significantly raised the hazard ratio for death.

Because high disease activity is also associated with an equally high mortality risk, “we have to balance this out: Active disease vs glucocorticoid use, especially in countries that have less access to modern therapies than we have in the more affluent Western regions,” Dr. Smolen said.

Rheumatology societies generally agree that clinicians should try to minimize GC use or eventually discontinue the therapy.

The American College of Rheumatology recommends not using GCs as part of the first-line treatment of RA. “And if you want to use [them], you should do that for less than 3 months, taper and discontinue as fast as possible, and use the lowest dose possible,” Dr. Adami said.

EULAR’s recommendation is more nuanced in that it allows for a lower dose but gives physicians more choice in how they want to handle GCs, Dr. Adami said. The task force added that all patients should try to taper down or discontinue as fast as possible, he said.

For GCs in the management of systemic lupus erythematosus, a EULAR task force recommended that the type and severity of organ involvement should determine dose, with a long-term goal of maintaining the dose < 5 mg/d or possibly withdrawing it.

EULAR also recommends GC bridging when initiating or changing conventional synthetic (cs) DMARDs. This effectively dismisses the use of GCs when using biologic DMARDs or targeted synthetic DMARDs. As a bridging therapy, EULAR recommends either a single parenteral dose of GC or a predefined tapering or discontinuation scheme within 3 months, when starting an oral GC.
 

Low-Dose Approach Gains Ground

While saying he’d be the first physician to eliminate GCs whenever possible, Dr. Buttgereit made the case before the EULAR Congress that GCs in low doses could still play a role in treatment.

Many physicians believe that very low doses between 2 and 4 mg/d are a realistic therapy option for RA, he said, adding that a mean daily usage < 5 mg could be used over a longer period with relatively low risk.

Several studies he coauthored tested the 5-mg approach. The GLORIA trial compared 5 mg/d prednisolone and placebo in 451 patients aged 65 years and older with active RA over the course of 2 years. The researchers found that patients on prednisolone had a mean Disease Activity Score in 28 joints (DAS28) that was 0.37 points lower and mean joint damage score that was 1.7 points lower than those of patients on placebo, suggesting that the GC had long-term benefits in these patients with RA.

The tradeoff was a 24% increase in the risk of having at least one adverse event of special interest, but most of these events were non-severe infections, Dr. Buttgereit said.

Another study, the SEMIRA trial, assigned 128 patients to a continued regimen of prednisone 5 mg/d for 24 weeks. Another group of 131 patients received a tapered-prednisone regimen. All patients received tocilizumab 162 mg with or without csDMARDs, maintained at stable doses.

Patients in the first cohort achieved superior disease activity control than those in the tapered regimen group. “The side effects showed that in the tapering prednisone group, there were more treatment-emergent adverse effects in this double-blind trial as compared to the continued prednisone group,” Dr. Buttgereit said.

One limitation of the SEMIRA trial was that it studied the effect of tocilizumab as a GC-sparing agent, and it didn’t consider using a tumor necrosis factor or Janus kinase (JAK) inhibitor, which might have a more potent effect on pain and GC dose reduction, Dr. Adami said. “Why do we need to use glucocorticoids if we know they might be detrimental, if we know there might be some other option in our armamentarium?”

Other studies have shown that low-dose GC protocols can be used with standard treatment, according to Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh School of Medicine.

“Examples of this are the LoVAS and PEXIVAS studies for antineutrophil cytoplasmic antibody-associated [ANCA] vasculitis. This has been highlighted in existing treatment recommendations for ANCA vasculitis and systemic lupus erythematosus nephritis,” Dr. Sattui said.

Debating the Toxicity Threshold

Are low GC dosages significantly associated with adverse events like mortality, cardiovascular, or diabetes risk? It depends on who you ask.

Much of the toxicity data on GCs come from inadequately powered or controlled studies and often refer to doses that currently are considered too high, Dr. Buttgereit said. His presentation highlighted a study from Hong Kong, a time-varying analysis of GC dose and incident risk for major adverse cardiovascular events (MACE) in more than 12,000 patients with RA. Researchers found that GC regimens ≥ 5 mg/d significantly increased the risk for MACE. Comparatively, doses below this threshold did not confer excessive risk, he said.

Low-dose GCs are lesser toxic than high-dose GCs, noted Joan Merrill, MD, a professor with the Arthritis and Clinical Immunology Research Program at The University of Oklahoma Health Sciences Center, Oklahoma City. “There may be less weight gain, less chance of acne, and less risk for all the slower, more organ-threatening side effects.”

Tapering Options Across Diseases

Rheumatologists in the field continue to navigate GC-tapering options and treatment combinations that reduce the cumulative use of GCs over time, finding their own solutions based on the conditions they treat.

In his EULAR presentation, Dr. Buttgereit suggested that current therapeutic approaches for RA may be too narrow when they don’t consider the possibility of including very low doses of GCs.

For RA, “why shouldn’t we not do a combination of something like methotrexate plus a JAK inhibitor or a biological,” plus a very low dose of GCs < 5 mg/d, he asked.

However, Dr. Adami said he generally avoids GCs if RA disease activity is not severe (based on DAS28) and if the patient has a visual analog scale pain score < 7. “Nonetheless, even in patients with more severe disease, I would avoid GCs for more than 3 months. Usually, 1 month of steroids, tapered rapidly and discontinued.”

All patients should receive an appropriate treat-to-target strategy with csDMARDs and biologics if needed, he added.

The priority is bone protection with an anti-osteoporosis medication. “I found that JAK inhibitors, in some cases, help with the discontinuation of steroids, especially in those with residual pain.

New treatment strategies in clinical trials show promise in reducing the tapering time of glucocorticoids (GCs) or possibly even replacing the use of GCs. Selective GC receptor agonists and modulators and GC plus hydroxysteroid dehydrogenase inhibitor combination therapy are some of the approaches under consideration.

“There is growing observational data that confirms the GC-sparing effect seen in some of these clinical trials in real-world data,” said Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh Medical Center, Pittsburgh.

GC minimization is an important goal, “and the data emerging from these trials should be reassuring for rheumatology providers,” Dr. Sattui said.

HSD-1 Inhibitors Under Study

11ß-Hydroxysteroid dehydrogenase type 1 (11ß-HSD1) is a tissue-specific intracellular modulator of GC action that’s been trialed for a number of rheumatic conditions. “HSD-1 deficiency or inhibition has been consistently associated with reduced GC side effects in mouse and human,” wrote the authors of a study testing the coadministration of HSD-1 inhibitor SPI-62 (clofutriben) with prednisolone in patients with polymyalgia rheumatica (PMR) to measure its impact on efficacy and toxicity.

Lead study author David Katz, PhD, chief scientific officer at Sparrow Pharmaceuticals, presented results at the at the annual European Congress of Rheumatology.

GCs are often the first-line therapy with PMR. However, it’s very difficult for patients to stop taking GCs once they start taking them. The study included patients with PMR who were taking 10 mg/d prednisolone and didn’t require a dose increase. For the study, they continued prednisolone without dose reduction for 4 weeks, receiving either SPI-62 6 mg/d or a matching placebo for 2 weeks.

During SPI-62 treatment, researchers in sequential cohorts maintained daily prednisolone doses at 10 mg, adjusted to 15 mg or adjusted to 20 mg.

A 10-mg dose of prednisolone combined with 6 mg of SPI-62 demonstrated less efficacy compared with placebo but improved upon prednisolone toxicities such as bone formation and resorption biomarkers, lipidemia, and insulin resistance. Doubling the dose to 20 mg prednisolone combined with SPI-62 achieved similar efficacy and maintained improvement of prednisolone toxicity markers.

“In patients with PMR, when we double the dose of prednisolone during coadministration with a potent HSD-1 inhibitor, we are able to have similar stability of symptoms, physical function, and systemic inflammation. At the same time, we are able to show improvements on biomarkers of bone turnover and insulin resistance,” Dr. Katz informed the EULAR 2024 audience.

An ongoing phase 2 clinical trial is testing SPI-62 in patients with endogenous Cushing syndrome. “It’s a longer-term trial, so we’re able to see at least an individual patient’s more clinical outcomes such as reversal of Cushing’s-associated myopathy and the ability of patients to discontinue all of their antidiabetic medications and yet still have good glycemic control,” he said.

Another research team from the United Kingdom explored whether AZD4017, an inhibitor of human 11ß-HSD1, could mitigate GC effects. The researchers randomly assigned 32 healthy male volunteers to AZD4017 or placebo, along with prednisolone. They reported a worsening of hepatic insulin sensitivity in the placebo group but not in the AZD4017 group, and protective effects of AZD4017 on markers of lipid metabolism and bone turnover, as well as lowered nighttime blood pressure. The results signified that coadministration of AZD4017 with prednisolone in men could be a way to reduce GC side effects.

In a Japanese phase 1/2 study, 11ß-HSD1 inhibitor S-707106 proved useful as an insulin sensitizer and antisarcopenic and anti-obesity medication in 16 patients with Cushing syndrome and autonomous cortisol secretion.
 

Novel Antitumor Necrosis Factor (TNF) Antibody Plus GC Receptor Modulator Conjugate

A novel antibody-drug conjugate comprising the anti-TNF monoclonal antibody adalimumab (ABBV-3373) linked to a GC receptor modulator shows promise as a GC alternative.

A notable 2022 study authored by Frank Buttgereit, MD, and other researchers assessed its safety and efficacy in a randomized, double-blind, active-controlled, proof-of-concept trial.

ABBV-3373 “was designed to potentially allow precise targeting of activated immune cells while significantly dampening inflammation and minimizing the systemic side effects associated with glucocorticoids,” according to AbbVie, its manufacturer.

A total of 48 adults with moderate to severe rheumatoid arthritis receiving background methotrexate were randomized to receive either ABBV-3373 (n = 31) or adalimumab (n = 17). The novel drug at 12 weeks showed a −2.65 reduction in the Disease Activity Score in 28 joints using C-reactive protein, compared with −2.13 for adalimumab. Researchers also predicted ABBV-3373 to be more effective than adalimumab based on in-trial and historical adalimumab data.

“We have great expectations for this molecule,” said Giovanni Adami, MD, PhD, a rheumatologist at the University of Verona, Verona, Italy, who has coauthored several studies on the use of GCs. Plans are underway for a phase 3 study with ABBV-3373.
 

C5a and Interleukin (IL)-6 Receptor Inhibitors as GC-Sparing Drugs

Investigators in a 2021 paper explored whether the C5a receptor inhibitor avacopan could effectively treat patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis without the need for daily GCs, following treatment with either cyclophosphamide or rituximab. They randomized 331 patients to receive avacopan or prednisone given on a tapering schedule for 20 weeks (60 mg/d tapered to discontinuation by week 21). “Avacopan was noninferior but not superior to prednisone taper with respect to remission at week 26 and was superior to prednisone taper with respect to sustained remission at week 52,” the investigators summarized.

A longer trial should test avacopan’s safety and durability in patients with ANCA-associated vasculitis, they recommended.

Sarilumab, a human monoclonal antibody that binds IL-6 receptor alpha and blocks the IL-6 pathway, yielded good results in the phase 3 SAPHYR trial as an alternative for patients with PMR who relapse while tapering prednisone therapy.

Researchers in the SAPHYR trial randomly assigned 118 patients 1:1 to receive a twice-monthly subcutaneous injection of sarilumab over 52 weeks plus a 14-week prednisone taper or placebo plus a 52-week prednisone taper. Patients in each group received a tapered GC dose initially at 15 mg/d for 2 weeks in a blinded fashion to control for disease at baseline.

Sarilumab effectively sustained remission in patients, significantly reducing the GC dose compared with placebo.

Disease flare after clinical remission took place in 57% of patients in the placebo group, vs 24% in the sarilumab group. “The placebo-treated patients had a fairly traditional 52-week GC taper. The patients treated with sarilumab had a very rapid GC taper,” said lead study author Robert Spiera, MD, director of the Scleroderma, Vasculitis and Myositis Center at the Hospital for Special Surgery, New York City.

In his own practice, Dr. Spiera often treats his patients with new-onset PMR with a fairly rapid GC taper, akin to what was used in SAPHYR, recognizing that a portion of these patients can be successfully treated with a relatively brief course of GCs, although the majority will need to have “rescue” therapy for flares with that approach.

They reported a worsening of hepatic insulin sensitivity in the placebo group but not in the AZD4017 group, and protective effects of AZD4017 on markers of lipid metabolism and bone turnover, as well as lowered nighttime blood pressure. The results signified that coadministration of AZD4017 with prednisolone in men could be a way to reduce GC side effects.

In a Japanese phase 1/2 study, 11ß-HSD1 inhibitor S-707106 proved useful as an insulin sensitizer and antisarcopenic and anti-obesity medication in 16 patients with Cushing syndrome and autonomous cortisol secretion.
 

Novel Antitumor Necrosis Factor (TNF) Antibody Plus GC Receptor Modulator Conjugate

A novel antibody-drug conjugate comprising the anti-TNF monoclonal antibody adalimumab (ABBV-3373) linked to a GC receptor modulator shows promise as a GC alternative.

A notable 2022 study authored by Frank Buttgereit, MD, and other researchers assessed its safety and efficacy in a randomized, double-blind, active-controlled, proof-of-concept trial.

ABBV-3373 “was designed to potentially allow precise targeting of activated immune cells while significantly dampening inflammation and minimizing the systemic side effects associated with glucocorticoids,” according to AbbVie, its manufacturer.

A total of 48 adults with moderate to severe rheumatoid arthritis receiving background methotrexate were randomized to receive either ABBV-3373 (n = 31) or adalimumab (n = 17). The novel drug at 12 weeks showed a −2.65 reduction in the Disease Activity Score in 28 joints using C-reactive protein, compared with −2.13 for adalimumab. Researchers also predicted ABBV-3373 to be more effective than adalimumab based on in-trial and historical adalimumab data.

“We have great expectations for this molecule,” said Giovanni Adami, MD, PhD, a rheumatologist at the University of Verona, Verona, Italy, who has coauthored several studies on the use of GCs. Plans are underway for a phase 3 study with ABBV-3373.
 

C5a and Interleukin (IL)-6 Receptor Inhibitors as GC-Sparing Drugs

Investigators in a 2021 paper explored whether the C5a receptor inhibitor avacopan could effectively treat patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis without the need for daily GCs, following treatment with either cyclophosphamide or rituximab. They randomized 331 patients to receive avacopan or prednisone given on a tapering schedule for 20 weeks (60 mg/d tapered to discontinuation by week 21). “Avacopan was noninferior but not superior to prednisone taper with respect to remission at week 26 and was superior to prednisone taper with respect to sustained remission at week 52,” the investigators summarized.

A longer trial should test avacopan’s safety and durability in patients with ANCA-associated vasculitis, they recommended.

Sarilumab, a human monoclonal antibody that binds IL-6 receptor alpha and blocks the IL-6 pathway, yielded good results in the phase 3 SAPHYR trial as an alternative for patients with PMR who relapse while tapering prednisone therapy.

Researchers in the SAPHYR trial randomly assigned 118 patients 1:1 to receive a twice-monthly subcutaneous injection of sarilumab over 52 weeks plus a 14-week prednisone taper or placebo plus a 52-week prednisone taper. Patients in each group received a tapered GC dose initially at 15 mg/d for 2 weeks in a blinded fashion to control for disease at baseline.

Sarilumab effectively sustained remission in patients, significantly reducing the GC dose compared with placebo.

Disease flare after clinical remission took place in 57% of patients in the placebo group, vs 24% in the sarilumab group. “The placebo-treated patients had a fairly traditional 52-week GC taper. The patients treated with sarilumab had a very rapid GC taper,” said lead study author Robert Spiera, MD, director of the Scleroderma, Vasculitis and Myositis Center at the Hospital for Special Surgery, New York City.

In his own practice, Dr. Spiera often treats his patients with new-onset PMR with a fairly rapid GC taper, akin to what was used in SAPHYR, recognizing that a portion of these patients can be successfully treated with a relatively brief course of GCs, although the majority will need to have “rescue” therapy for flares with that approach.

New treatment strategies in clinical trials show promise in reducing the tapering time of glucocorticoids (GCs) or possibly even replacing the use of GCs. Selective GC receptor agonists and modulators and GC plus hydroxysteroid dehydrogenase inhibitor combination therapy are some of the approaches under consideration.

“There is growing observational data that confirms the GC-sparing effect seen in some of these clinical trials in real-world data,” said Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh Medical Center, Pittsburgh.

GC minimization is an important goal, “and the data emerging from these trials should be reassuring for rheumatology providers,” Dr. Sattui said.

HSD-1 Inhibitors Under Study

11ß-Hydroxysteroid dehydrogenase type 1 (11ß-HSD1) is a tissue-specific intracellular modulator of GC action that’s been trialed for a number of rheumatic conditions. “HSD-1 deficiency or inhibition has been consistently associated with reduced GC side effects in mouse and human,” wrote the authors of a study testing the coadministration of HSD-1 inhibitor SPI-62 (clofutriben) with prednisolone in patients with polymyalgia rheumatica (PMR) to measure its impact on efficacy and toxicity.

Lead study author David Katz, PhD, chief scientific officer at Sparrow Pharmaceuticals, presented results at the at the annual European Congress of Rheumatology.

GCs are often the first-line therapy with PMR. However, it’s very difficult for patients to stop taking GCs once they start taking them. The study included patients with PMR who were taking 10 mg/d prednisolone and didn’t require a dose increase. For the study, they continued prednisolone without dose reduction for 4 weeks, receiving either SPI-62 6 mg/d or a matching placebo for 2 weeks.

During SPI-62 treatment, researchers in sequential cohorts maintained daily prednisolone doses at 10 mg, adjusted to 15 mg or adjusted to 20 mg.

A 10-mg dose of prednisolone combined with 6 mg of SPI-62 demonstrated less efficacy compared with placebo but improved upon prednisolone toxicities such as bone formation and resorption biomarkers, lipidemia, and insulin resistance. Doubling the dose to 20 mg prednisolone combined with SPI-62 achieved similar efficacy and maintained improvement of prednisolone toxicity markers.

“In patients with PMR, when we double the dose of prednisolone during coadministration with a potent HSD-1 inhibitor, we are able to have similar stability of symptoms, physical function, and systemic inflammation. At the same time, we are able to show improvements on biomarkers of bone turnover and insulin resistance,” Dr. Katz informed the EULAR 2024 audience.

An ongoing phase 2 clinical trial is testing SPI-62 in patients with endogenous Cushing syndrome. “It’s a longer-term trial, so we’re able to see at least an individual patient’s more clinical outcomes such as reversal of Cushing’s-associated myopathy and the ability of patients to discontinue all of their antidiabetic medications and yet still have good glycemic control,” he said.

Another research team from the United Kingdom explored whether AZD4017, an inhibitor of human 11ß-HSD1, could mitigate GC effects. The researchers randomly assigned 32 healthy male volunteers to AZD4017 or placebo, along with prednisolone.

TORONTO — Dermatologists should prescribe emergency contraception (EC) to adolescent patients being treated with isotretinoin for acne.

That was one of the main messages from Andrea L. Zaenglein, MD, professor of dermatology and pediatrics, Penn State University, Hershey, who discussed hormonal therapies for pediatric acne at the annual meeting of the Society for Pediatric Dermatology.

Many doctors are reluctant to prescribe EC, which refers to contraceptive methods used to prevent unintended pregnancy after unprotected sexual intercourse or contraceptive failure, whether that’s from discomfort with EC or lack of training, Dr. Zaenglein said in an interview.

Isotretinoin, a retinoid marketed as Accutane and other brand names, is an effective treatment for acne but carries serious teratogenicity risks; the iPLEDGE Risk Evaluation and Mitigation Strategy is designed to manage this risk and minimize fetal exposure. Yet from 2011 to 2017, 210-310 pregnancies per year were reported to the Food and Drug Administration, according to a 2019 study.

There is a knowledge gap regarding EC among dermatologists who prescribe isotretinoin, which “is perpetuated by the iPLEDGE program because it is inadequate in guiding clinicians or educating patients about the use of EC,” Dr. Zaenglein and colleagues wrote in a recently published viewpoint on EC prescribing in patients on isotretinoin.

Types of EC include oral levonorgestrel (plan B), available over the counter; oral ulipristal acetate (ella), which requires a prescription; and the copper/hormonal intrauterine device.

Not all teens taking isotretinoin can be trusted to be sexually abstinent. Dr. Zaenglein cited research showing 39% of female high school students have had sexual relations. “In my opinion, these patients should have emergency contraception prescribed to them as a backup,” she said.

Dr. Zaenglein believes there’s a fair amount of “misunderstanding” about EC, with many people thinking it’s an abortion pill. “It’s a totally different medicine. This is contraception; if you’re pregnant, it’s not going to affect your fetus.”

Outgoing SPD President Sheilagh Maguiness, MD, professor of dermatology and pediatrics, University of Minnesota, Minneapolis, agreed that Dr. Zaenglein raised an important issue. “She has identified a practice gap and a knowledge gap that we need to address,” she said in an interview.

When discussing contraception with female patients taking isotretinoin, assume they’re sexually active or could be, Dr. Zaenglein told meeting attendees. Be explicit about the risks to the fetus and consider their past compliance.
 

Complex Disorder

During her presentation, Dr. Zaenglein described acne as a “very complex, multifactorial inflammatory disorder” of the skin. It involves four steps: Increased sebum production, hyperkeratinization, Cutibacterium acnes, and inflammation. External factors such as diet, genes, and the environment play a role.

“But at the heart of all of it is androgens; if you didn’t have androgens, you wouldn’t have acne.” That’s why some acne treatments block androgen receptors.

Clinicians are increasingly using one such therapy, spironolactone, to treat acne in female adolescents. Dr. Zaenglein referred to a Mayo Clinic study of 80 patients (mean age, 19 years), who had moderate to severe acne treated with a mean dose of 100 mg/day, that found 80% had improvement with a favorable side effect profile. This included nearly 23% who had a complete response (90% or more) and 36% who had a partial response (more than 50%); 20% had no response.

However, response rates are higher in adults, said Dr. Zaenglein, noting that spironolactone works “much better” in adult women.

Side effects of spironolactone can include menstrual disturbances, breast enlargement and tenderness, and premenstrual syndrome–like symptoms.

Dermatologists should also consider combined oral contraceptives (COCs) in their adolescent patients with acne. These have an estrogen component as well as a progestin component.

They have proven effectiveness for acne in adolescents, yet a US survey of 170 dermatology residents found only 60% felt comfortable prescribing them to healthy adolescents. The survey also found only 62% of respondents felt adequately trained on the efficacy of COCs, and 42% felt adequately trained on their safety.

Contraindications for COCs include thrombosis, migraine with aura, lupus, seizures, and hypertension. Complex valvular heart disease and liver tumors also need to be ruled out, said Dr. Zaenglein. One of the “newer concerns” with COCs is depression. “There’s biological plausibility because, obviously, hormones impact the brain.”
 

Preventing Drug Interactions

Before prescribing hormonal therapy, clinicians should carry out an acne assessment, aimed in part at preventing drug interactions. “The one we mostly have to watch out for is rifampin,” an antibiotic that could interact with COCs, said Dr. Zaenglein.

The herbal supplement St John’s Wort can reduce the efficacy of COCs. “You also want to make sure that they’re not on any medicines that will increase potassium, such as ACE inhibitors,” said Dr. Zaenglein. But tetracyclines, ampicillin, or metronidazole are usually “all okay” when combined with COCs.

It’s important to get baseline blood pressure levels and to check these along with weight on a regular basis, she added.

Always Consider PCOS

Before starting hormonal therapy, she advises dermatologists to “always consider” polycystic ovary syndrome (PCOS), a condition that’s “probably much underdiagnosed.” Acne is common in adolescents with PCOS. She suggests using a PCOS checklist, a reminder to ask about irregular periods, hirsutism, signs of insulin resistance such as increased body mass index, a history of premature adrenarche, and a family history of PCOS, said Dr. Zaenglein, noting that a person with a sibling who has PCOS has about a 40% chance of developing the condition.

“We play an important role in getting kids diagnosed at an early age so that we can make interventions because the impact of the metabolic syndrome can have lifelong effects on their cardiovascular system, as well as infertility.”

Dr. Zaenglein is a member of the American Academy of Dermatology (AAD) Acne Guidelines work group, the immediate past president of the American Acne and Rosacea Society, a member of the AAD iPLEDGE work group, co–editor in chief of Pediatric Dermatology, an advisory board member of Ortho Dermatologics, and a consultant for Church & Dwight. Dr. Maguiness had no relevant conflicts of interest.
