With positive phase IIa cardiovascular disease results in hand, Marea Therapeutics Inc. said it is ready to move on to a phase IIb study sometime in the second quarter of 2025. MAR-001, a monoclonal antibody targeting the protein coding gene ANGPTL4, produced an up to a 52.5% placebo-adjusted mean reduction in remnant cholesterol and up to a 52.7% placebo-adjusted mean reduction in triglycerides at 12 weeks.

The U.S. FDA approval of Johnson & Johnson’s Imaavy (nipocalimab-aahu) for myasthenia gravis brings the monoclonal antibody into a treatment space that teems with competition, both approved and in-development candidates. The human Fc receptor inhibitor was approved to treat generalized myasthenia gravis in patients who are 12 years and older. Patients must be anti-acetylcholine receptor [AChR] or anti-muscle-specific kinase [MuSK] antibody positive. Anti-AChR and anti-MuSK antibody-positive individuals make up more than 90% of all antibody-positive gMG patients.

The intriguing VEGFxPD-1 bispecific antibody space gained oomph with phase III results disclosed April 23 by Akeso Pharmaceuticals Inc. related to Harmoni-6, testing ivonescimab in combination with platinum-based chemotherapy compared with Tevimbra (tislelizumab, Beigene Ltd.), a PD-1 inhibitor also paired with platinum-based chemo in patients with locally advanced or metastatic squamous non-small-cell lung cancer irrespective of PD-L1 expression. Those data were followed by a green light from the U.S. FDA April 24 for marketing the PD-1 monoclonal antibody penpulimab in combination with cisplatin or carboplatin and gemcitabine for the first-line treatment of adult recurrent or metastatic non-keratinizing nasopharyngeal carcinoma.

If U.S. sectoral tariffs on biopharmaceuticals become a reality and most country-by-country tariffs on other medical products resume, manufacturers may have to rethink their use of U.S. free trade zones to turn foreign-sourced active pharmaceutical ingredients and other components into finished products for the U.S. market.

The U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) and medical research charity Lifearc have announced a collaboration to develop an affordable and accessible monoclonal antibody (mAb) therapeutic for Crimean-Congo hemorrhagic fever virus (CCHFV).

China’s National Medical Products Administration has given the thumbs up to Akeso Pharmaceuticals Inc.’s ebdarokimab for treating moderate to severe plaque psoriasis in adults.
