Swissmedic Launches Fast-Track Clinical Trial Review to Accelerate Patient Access to Life-Saving Treatments

  • Swissmedic introduces a pilot fast-track procedure for clinical trial applications, reducing review times from 30 to 20 days for known investigational drugs and from 60 to 40 days for first-in-human studies.
  • The accelerated process prioritizes studies addressing high medical need where no approved treatment options exist in Switzerland, positioning the country ahead of EU standards.
  • The pilot program runs from July 2025 through 2026, with potential permanent implementation by 2027, while maintaining all safety requirements and regulatory standards.
  • This initiative aims to strengthen Switzerland's position as a leading clinical research location and provide patients faster access to innovative, potentially life-saving therapies.

Complement-Based Drug Development Gains Momentum Following FDA Approvals and Pipeline Advances

  • The complement-based therapeutics field is experiencing significant growth following recent FDA approvals, including Novartis' alternative complement inhibitor for PNH and SYFOVRE approval.
  • Multiple complement inhibitors are advancing through clinical trials across diverse therapeutic areas including nephrology, ophthalmology, neurodegeneration, and inflammation.
  • Industry focus is expanding beyond rare diseases to larger patient populations, with companies exploring combination therapies and indication expansion strategies.
  • The 8th Annual Complement-Based Drug Development Summit will convene 100+ industry leaders to address key challenges in complement pathway targeting and clinical trial design.

FDA Approves Streamlined Access for Bristol Myers Squibb CAR T Cell Therapies

  • The FDA has approved label updates for Bristol Myers Squibb's CAR T cell therapies Breyanzi and Abecma, reducing patient monitoring requirements and removing Risk Evaluation and Mitigation Strategy (REMS) programs.
  • Key changes include reducing driving restrictions from 8 weeks to 2 weeks post-treatment and decreasing the requirement to stay near healthcare facilities from 4 weeks to 2 weeks following infusion.
  • These updates reflect growing real-world evidence from over 30,000 patients treated with CAR T cell therapy, with studies showing most serious adverse events occur within the first two weeks of infusion.
  • Currently only about 2 in 10 eligible patients receive cell therapy treatment due to logistical and geographic barriers, which these label changes aim to address.

FDA Rejects Accelerated Approval for Edgewise's Sevasemten in Becker Muscular Dystrophy

  • The FDA declined to consider Edgewise Therapeutics' sevasemten for accelerated approval in Becker muscular dystrophy, citing insufficient data from the Phase II CANYON trial.
  • The agency affirmed that North Star Ambulatory Assessment scores can serve as a clinically meaningful endpoint for traditional approval, providing a clear regulatory pathway forward.
  • Edgewise must now rely on its ongoing Phase III GRAND CANYON trial, which is expected to read out in Q4 2026 and is designed to demonstrate statistical significance versus placebo.
  • The company's stock dropped 10% following the announcement, though analysts noted the decision was not unexpected given the FDA's tightened stance on accelerated approval requirements.

Zenocutuzumab Achieves 30% Response Rate in NRG1 Fusion-Positive Solid Tumors, Receives FDA Approval

  • The Phase 2 eNRGy trial demonstrated zenocutuzumab's clinical efficacy with a 30% objective response rate and 11.1-month median duration of response in patients with NRG1 fusion-positive solid tumors.
  • Pancreatic cancer patients showed particularly promising results with a 42% response rate and 9.2-month median progression-free survival, offering hope for this historically difficult-to-treat malignancy.
  • Zenocutuzumab received accelerated FDA approval as the first targeted therapy for NRG1-positive non-small cell lung cancer and pancreatic adenocarcinoma.
  • The bispecific antibody demonstrated a favorable safety profile with treatment-related adverse events in 95% of participants but fewer than 10% experiencing grade 3 or higher toxicities.

First European Patient Receives Breakthrough Treatment for Ultra-Rare APDS Immune Disorder

  • Mary Catchpole, 19, becomes the first European patient to receive leniolisib (Joenja), a newly approved targeted treatment for activated PI3-kinase delta syndrome (APDS), a rare inherited immune disorder.
  • The drug works by inhibiting an overactive enzyme that disrupts immune function, offering a potential cure for patients who previously faced lifelong infections and invasive treatments.
  • APDS was discovered by Cambridge researchers in 2013 with help from Catchpole's family, who lost four members to the condition before this breakthrough treatment became available.
  • The NHS approved leniolisib at a list price of £352,000 per year with a confidential discount, potentially benefiting up to 50 patients over age 12 in England.

China Approves First Once-Daily Nebulized LAMA for COPD, Triggering $7.5M Milestone for Theravance

  • China's NMPA has approved YUPELRI (revefenacin) as the first once-daily nebulized long-acting muscarinic antagonist for maintenance treatment of chronic obstructive pulmonary disease.
