Tourmaline Bio, Inc. announced plans to commence a Phase 2 trial evaluating quarterly subcutaneous dosing of TOUR006 in patients with elevated cardiovascular risk in the first half of 2024. Data from this Phase 2 trial are expected in the first half of 2025. TOUR006 is a long-acting, fully-human, anti-IL-6 monoclonal antibody with best-in-class potential and differentiated properties including a naturally long half-life, low immunogenicity, and high binding affinity to IL-6. To date, TOUR006 has been studied in 448 participants, including patients with autoimmune disorders, across six clinical trials.

Tourmaline is developing TOUR006 in TED and ASCVD as its first two indications, with additional diseases under consideration.
