Mestag Therapeutics Ltd. has raised a $40 million round from existing investors as it completes final preparations for its lead program MST-0312 to enter clinical development in mid-2026. MST-0312 is a bispecific antibody aimed at the lymphotoxin-β receptor (LTBR), which is essential for the development of lymphoid tissues.

In a recent publication, researchers from Johnson & Johnson presented a bispecific antibody – JNJ-79032421 – targeting CD3 on T cells and the membrane-restricted, non-shed region of full-length mesothelin (MSLN) on cancer cells.

Akeso Inc.’s first-in-class trispecific antibody, AK-150, has received IND clearance from China’s National Medical Products Administration (NMPA) for clinical trials in patients with advanced solid tumors. Engineered using Akeso’s AI-driven drug discovery platform and its proprietary Tetrabody technology, AK-150 is a humanized anti-CSF-1R, ILT2 and ILT4 trispecific antibody that achieves multipathway blockade of both innate and adaptive immunity.

Enodia Therapeutics SAS has acquired Kezar Life Sciences Inc.’s assets from its Sec61-based discovery and development program, including clinical-stage KZR-261. Insights from Kezar’s Sec61-based programs will further strengthen Enodia’s core focus on Sec61-driven selectivity for targeting protein degradation.
