Over 10 companies are developing 12+ RIPK1 inhibitor therapies targeting inflammatory and neurodegenerative diseases, with key players including Sanofi, Rigel Pharmaceuticals, and GenFleet Therapeutics advancing promising candidates.
Sanofi discontinued its Phase 2 trial of oditrasertib in multiple sclerosis after failing to meet primary endpoints, highlighting the challenges in targeting neurodegeneration with RIPK1 inhibition.
Leading pipeline candidates include SAR443122 for cutaneous lupus and ulcerative colitis, GFH312 as China's first clinical-stage RIPK1 inhibitor, and R552 developed through Rigel's collaboration with Eli Lilly.
RIPK1 inhibitors represent a novel therapeutic approach by blocking inflammation and cell death pathways, offering potential treatments for autoimmune disorders, neurodegenerative conditions, and inflammatory diseases.
