Novartis starts Phase 2 trial of MRT‑6160 for psoriatic arthritis

Novartis has begun a Phase 2a/b clinical study of MRT‑6160, a VAV1‑targeting molecular‑glue degrader, in patients with moderate to severe psoriatic arthritis. The trial is randomized, double‑blind, placebo‑controlled and multicenter. Under the global exclusive license with Monte Rosa Therapeutics, Novartis will fund and run the study, while Monte Rosa will receive a $37.5 million milestone payment and remains eligible for up to $2.1 billion in additional milestones and royalties.

The milestone payment provides Monte Rosa with immediate cash and the agreement gives the company exposure to a potentially large market for psoriatic arthritis treatments. Investors should note that the partnership places development risk and cost on Novartis, while Monte Rosa retains upside from future milestones and a share of U.S. profits.
