Monte Rosa Therapeutics Announces FDA Clearance of IND Application for MRT-8102, a NEK7-Directed Molecular Glue Degrader for the Treatment of Multiple Inflammatory Diseases

Core Viewpoint - Monte Rosa Therapeutics has received FDA clearance for the Investigational New Drug (IND) application of MRT-8102, a NEK7-directed molecular glue degrader aimed at treating inflammatory diseases linked to NLRP3, IL-1β, and IL-6 dysregulation, with initial clinical results expected in H1 2026 [1][2][4] Group 1: Product Development - MRT-8102 is designed to selectively target NEK7, potentially addressing multiple inflammatory diseases, including cardio-immunology, rheumatology, and respiratory conditions [2][4] - The Phase 1 study of MRT-8102 is set to begin shortly, with results anticipated in H1 2026, focusing on safety, pharmacokinetics, NEK7 protein degradation, and key pharmacodynamic markers [1][2] - Preclinical studies have shown MRT-8102's ability to achieve nanomolar-level degradation of NEK7 without off-target activity, indicating a strong safety profile with over a 200-fold exposure margin compared to projected human efficacious doses [2][4] Group 2: Clinical and Preclinical Insights - In non-human primate models, MRT-8102 demonstrated near-complete inhibition of downstream inflammatory markers and improvements in pathological measures in inflammatory disease models [2][4] - In a rabbit gout model, daily oral dosing of MRT-8102 resulted in reduced joint swelling and improved histopathology scores [2] - The company plans to establish initial proof-of-concept for cardio-immunology indications by evaluating changes in C-reactive protein (CRP) and other inflammatory markers in subjects with elevated CRP levels [2] Group 3: Future Directions - Monte Rosa is also advancing a second-generation NEK7 program with enhanced CNS penetration, with an IND submission expected in 2026 [3] - The company retains full worldwide rights to MRT-8102 and its second-generation NEK7 molecular glue degraders [3] - Monte Rosa aims to establish molecular glue degraders as a significant modality in immunology and inflammatory indications, following the success of MRT-6160 [2]
