Novartis drops TREM2 antibody in ALS after Phase 2 miss
Novartis discontinued VHB937, a TREM2 antibody for ALS, after a Phase 2 trial missed its primary endpoint. The trial tested the drug in 251 early-stage ALS patients. Novartis did not release numerical data, with detailed findings expected in December. The setback follows recent failures in Novartis' pipeline, including pelacarsen and del-desiran. ALS drug development has seen many failures, with no current treatments stopping or reversing the disease.
