selnoflast (RG6418) / Roche - LARVOL DELTA

A PHASE 1B STUDY TO TEST THE SAFETY, PHARMACOKINETICS, AND PHARMACODYNAMICS OF SELNOFLAST IN EARLY-STAGE PARKINSON'S DISEASE: STUDY DESIGN AND BASELINE CHARACTERISTICS (ADPD 2025) - "Conclusions The recruited participants' baseline characteristics are in line with those of an early-stage PD population. The effect of selnoflast on activated microglia, as measured by TSPO-PET imaging and CSF NLRP3-related markers, may serve as proof-of-mechanism for NLRP3 inhibitors and other novel neuroinflammation targets."

A randomized, double-blind phase 1b study evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics of the NLRP3 inhibitor selnoflast in patients with moderate to severe active ulcerative colitis. (PubMed, Clin Transl Med) - "Selnoflast was safe and well-tolerated. Selnoflast 450 mg QD achieved plasma and tissue exposure predicted to maintain IL-1β IC over the dosing interval. However, PD biomarker results showed no robust differences between treatment arms, suggesting no major therapeutic effects are to be expected in UC. The limitations of this study are its small sample size and indirect assessment of the effect on IL-1β in tissue."
