Bristol Myers Squibb Partners with BioNTech in $11.1 Billion Deal for Dual-Target Cancer Immunotherapy

  • Bristol Myers Squibb will pay BioNTech $1.5 billion upfront plus $2 billion in anniversary payments through 2028 for a 50% partnership in BNT327, a bispecific antibody targeting both PD-L1 and VEGF proteins.
  • BNT327 represents a new class of cancer immunotherapies that simultaneously targets two of the most important cancer drug targets, following the success of ivonescimab which outperformed Keytruda in Phase 3 lung cancer trials.
  • The experimental drug is currently in Phase 3 trials for both small cell and non-small cell lung cancer, with a third late-stage trial in triple-negative breast cancer planned to start by year-end.
  • This partnership positions Bristol Myers to compete in the emerging bispecific antibody race alongside Pfizer, Merck, Akeso, and Summit Therapeutics in what could become a foundational immuno-oncology treatment approach.

Vera Therapeutics' Atacicept Achieves 46% Protein Reduction in Phase 3 IgA Nephropathy Trial

  • Vera Therapeutics' atacicept demonstrated a statistically significant 46% reduction in proteinuria in patients with IgA nephropathy, exceeding the 35% reduction seen in Phase 2 trials.
  • The positive ORIGIN 3 Phase 3 results drove Vera's stock price up over 65% in pre-market trading, with the company planning FDA submission in Q4 2025.
  • Atacicept faces competition from Otsuka Holdings' sibeprenlimab, which has already filed for FDA approval and may reach market 6-9 months earlier than Vera's drug.
  • IgA nephropathy affects up to 50% of patients who may progress to end-stage kidney disease, representing a significant unmet medical need in nephrology.

Viatris Reports Positive Phase 3 Results for MR-142 in Treating Night Vision Disturbances After Refractive Surgery
