MDMA-ASSISTED THERAPY FOR PTSD REJECTED BY FDA PANEL
The U.S. Food and Drug Administration’s (FDA) Psychopharmacologic Drugs Advisory Committee convened in early June 2024 to review the NDA for midomafetamine (MDMA) capsules in combination with psychological intervention (“MDMA-assisted therapy”) for the treatment of post-traumatic stress disorder (PTSD) in adults. The committee voted 9 to 2 against the available data showing that MDMA is effective in patients with PTSD. The committee also voted 10 to 1 against whether the benefits of MDMA with the FDA’s proposed Risk Evaluation and Mitigation Strategies (REMS) outweigh the risks. Although the FDA is not required to follow its advisory panels’ guidance, it is usually taken into consideration during the decision process. A decision regarding approval of MDMA capsules is expected by the Prescription Drug User Fee Act (PDUFA) date of August 11, 2024. MDMA, also known as “molly” or “ecstasy,” is administered orally in a clinic and acts on multiple neurotransmitters (e.g., serotonin, noradrenaline, dopamine) potentially alleviating fear responses and allowing for trauma-focused therapy sessions.
The committee reviewed data from two randomized, double-blind, placebo-controlled, phase 3 studies (Multi-Site Phase 3 Study of MDMA-Assisted Psychotherapy for PTSD [MAPP1 and MAPP2]) assessing MDMA in combination with psychological intervention (e.g., psychotherapy, other services provided by a qualified HCP) versus placebo in combination with psychological intervention in 194 adults with severe or moderate to severe PTSD. The Institute for Clinical and Economic Review (ICER) also reviewed the results from these two short-term studies and performed a meta-analysis of the data, which is detailed in ICER’s Revised Evidence Report. Compared with the control arm, patients receiving MDMA-assisted therapy were more likely to be treatment responders (relative risk [RR], 1.32) as well as achieve a loss of diagnosis of PTSD (RR, 1.7) and meet criteria for PTSD remission (RR, 2.86). However, ICER has raised substantial concerns regarding the validity of the results. Per ICER, due to the physiological effects of MDMA, patients in the MDMA study arm were in essence unblinded as most could correctly determine they had received the MDMA-assisted therapy. The potential for bias was further enhanced as experts stated the investigators, therapists, and patients involved in the trial held very strong beliefs regarding the efficacy of MDMA-assisted therapy, and therapists involved in the study persuaded favorable patient reports and dissuaded negative patient reports. This could potentially include the discouragement of substantial harm from the therapy, impacting the benefits versus risks analysis. ICER was only able to perform a limited review of these concerns and was unable to determine the frequency of misreporting. As a result, ICER concluded evidence for MDMA-assisted therapy is insufficient. Furthermore, MDMA-assisted therapy could not be adequately compared with trauma-focused psychotherapies due to insufficient evidence. The final ICER Evidence Report on MDMA-assisted therapy for PTSD is expected on June 27, 2024.

DRUG INFORMATION HIGHLIGHTS
- In the FLOW trial, 3,533 patients with T2DM and chronic kidney disease were randomized to either semaglutide (Ozempic) 1 mg SC weekly or placebo and were followed for a median of 3.4 years, after early trial cessation based on a prespecified interim analysis. The risk of a primary outcome event (composite of onset of kidney failure, ≥ 50% reduction in eGFR from baseline, or death from kidney-related or cardiovascular [CV] causes) was reduced by 24% with semaglutide versus placebo (331 versus 410 first events; HR, 0.76, 95% CI, 0.66 to 0.88, p=0.0003). Confirmatory secondary outcomes also showed a benefit of semaglutide, and serious adverse reactions occurred in fewer patients in the semaglutide arm than placebo (49.6% versus 53.8%).
- The CDC has recommended influenza surveillance systems continue to operate at heightened levels during the summer to aid in detection of rare cases of human H5N1 virus infection. Furthermore, the agency recommends an increase in the number of positive influenza A virus samples subtyped. The intent of the increased monitoring through the summer is due to the ongoing outbreak of H5N1 among poultry and U.S. dairy cattle.
- The CDC has published an MMWR outlining recommendations for use of doxycycline postexposure prophylaxis (PEP) for bacterial sexually transmitted infection prevention in select populations. The recommended dose for doxycycline PEP is 200 mg taken within 72 hours of sexual contact.
- Sanofi-Aventis has announced discontinuation of insulin glargine 100 IU/mL injection, an unbranded biologic for Lantus, due to a business decision. Lantus remains on the market.
- Actelion/Philips Respironics has announced discontinuation of the I-neb® AAD® system as well as associated supplies (e.g., medication discs used for administering the solution). Iloprost (Ventavis) solution in the strengths of 10 ug/mL and 20 ug/mL is also being discontinued.
- Par has announced discontinuation of the 40 mg/1 mL strength of brand-name Delestrogen (estradiol valerate) injection. Generics from other manufacturers remain available.
DRUG INFORMATION HAPPENINGS
- The AHA and American College of Cardiology (ACC) published updated recommendations for management of lower extremity peripheral artery disease (PAD). The guideline defines four clinical subsets of PAD (asymptomatic PAD, chronic symptomatic PAD, chronic limb-threatening ischemia, acute limb ischemia) and details effective treatment to prevent major adverse CV events and major adverse limb events.
- The American Academy of Neurology (AAN), American Epilepsy Society, and Society for Maternal-Fetal Medicine has issued a guideline for use of antiseizure medications (ASMs) in people with epilepsy of childbearing potential (PWECP). According to the guideline, HCPs should recommend ASMs and doses that optimize seizure control and fetal outcomes at the earliest possible opportunity prior to conception. To reduce the risk for major congenital malformations, lamotrigine, levetiracetam, or oxcarbazepine should be considered when appropriate, and valproic acid should be avoided when possible.
- The European Society of Endocrinology and the Endocrine Society have released a clinical guideline for diagnosis and management of glucocorticoid-induced adrenal insufficiency. The guideline includes recommendations for tapering of systemic glucocorticoid therapy for non-endocrine conditions, diagnosis and approach to glucocorticoid-induced adrenal insufficiency and glucocorticoid withdrawal syndrome, and diagnosis and treatment of adrenal crisis.
- The ACC and the AHA published updated clinical practice guidelines for the management of hypertrophic cardiomyopathy (HCM). New recommendations include: (1) for younger patients (e.g., age ≤ 45 years of age) with a mild phenotype of nonobstructive HCM due to a pathogenic or likely pathogenic cardiac sarcomere genetic variant, valsartan may be useful to slow unfavorable cardiac remodeling; (2) in patients with HCM who develop persistent systolic dysfunction with LVEF < 50%, discontinue cardiac myosin inhibitors; and (3) mavacamten is contraindicated in pregnant women due to potential teratogenic effects.
