Late September brought a wave of significant developments across the clinical trial landscape, from a landmark publication in Pulmonary Arterial Hypertension (PAH) to major M&A deals in oncology and obesity. Regulators in the US, EU, and UK were active with key approvals and pilot programs aimed at streamlining research. Here’s a breakdown of the essential news.
Pivotal Study Publications & Data
- Sotatercept Shows Major Promise in PAH (NEJM): The Phase 3 HYPERION trial results, published in the New England Journal of Medicine, demonstrated that sotatercept significantly reduced the risk of clinical worsening in newly diagnosed patients with Pulmonary Arterial Hypertension compared to placebo. This publication strengthens the case for using the treatment earlier in the disease course and could shift the standard of care. Read the Study
- Antibody Biomarker Shifts Post-MI (Nature Medicine): A Phase 2 study highlighted in Nature Medicine found that an anti-LOX-1 antibody led to significant biomarker changes in post-myocardial infarction patients, even without a substantial reduction in plaque volume, providing new insights into cardiovascular disease mechanisms. See Nature Medicine Highlights
Regulatory & Approval Highlights
United States (FDA)
- First Treatment for Barth Syndrome Approved: The FDA granted Accelerated Approval to Forzinity (elamipretide), the first-ever therapy for the ultra-rare and serious mitochondrial disorder, Barth syndrome. FDA Announcement
- First-of-its-Kind Eyeglass Lenses Authorized: In a De Novo authorization, the FDA cleared Essilor's Stellest lenses, the first device clinically proven to slow the progression of myopia (nearsightedness) in children. FDA Press Release
European Union (EMA)
- CHMP Recommends 14 New Medicines: The EMA’s Committee for Medicinal Products for Human Use (CHMP) issued positive opinions for a wide range of therapies, including nipocalimab for generalized myasthenia gravis (gMG), elinzanetant for vasomotor symptoms (VMS), and a combination of insulin icodec/semaglutide for Type 2 Diabetes. The recommendations also included nine biosimilars, signaling a continued push for competition and access. EMA Meeting Highlights
United Kingdom (MHRA)
- New Glioma Treatment Approved: The MHRA approved vorasidenib (Voranigo) for patients with IDH-mutant Grade 2 glioma, offering a new targeted therapy for this type of brain tumor. MHRA Announcement
- Pilot Launched to Speed Up Trial Modifications: The MHRA has launched its "Route B" notification pilot (Oct 1–Mar 31), which aims to reduce response times for substantial trial modifications to approximately 14 days, potentially accelerating trial iteration in the UK. Learn about the Pilot
Industry Trends & Global Policy
- WHO Pushes for Global Trial Transparency: Major global research funders released a joint statement via the World Health Organization (WHO), committing to strengthening clinical trial registration and results reporting worldwide to improve transparency and quality. WHO News Release
- M&A Activity Signals Focus on Oncology and Obesity: Several multi-billion dollar deals underscored sustained investment in high-value therapeutic areas:
- Genmab to acquire Merus for ~$8B, centered on its head and neck cancer asset petosemtamab.
- Pfizer to acquire Metsera for ~$4.9B to bolster its obesity and metabolic disease pipeline.
- Biogen acquired Alcyone for $85M to gain access to its intrathecal drug delivery technology.
