Monte Rosa Therapeutics Announces Global License Agreement With Novartis to Advance T & B Cell-Modulating VAV1-Directed Molecular Glue Degraders

Monte Rosa Therapeutics, Inc. recently announced a global exclusive development and commercialization license agreement with Novartis to advance VAV1 MGDs, including MRT-6160. MRT-6160 is currently in an ongoing Phase 1, single ascending dose (SAD)/multiple ascending dose (MAD) healthy volunteer study for immune-mediated conditions. Under the terms of the agreement, Novartis will obtain exclusive worldwide rights to develop, manufacture and commercialize MRT-6160 and other VAV1 MGDs and will be responsible for all clinical development and commercialization, starting with Phase 2 clinical studies. Monte Rosa remains responsible for completion of the ongoing Phase 1 clinical study of MRT-6160.

“We are thrilled to announce this agreement with Novartis, a key player in immune-mediated conditions, and we are excited about the transformative potential it provides for Monte Rosa and MRT-6160. We expect this will accelerate and broaden the scope of clinical development of MRT-6160 to advance this unique, orally bioavailable modality while retaining substantial value for Monte Rosa. We believe the transaction validates our unique and industry leading QuEEN discovery engine, and it further increases our conviction to rationally design and develop highly selective and safe MGDs for undruggable targets, including in the areas of immunology and inflammation, metabolism, and genetic diseases,” said Markus Warmuth, MD, Chief Executive Officer of Monte Rosa Therapeutics. “The financial resources provided by this agreement are expected to extend our operational runway, enable us to advance our pipeline to potential value-creating milestones and anticipated proof-of-concept readouts, and further leverage our QuEEN™ discovery engine.”

“Novartis has had a long-standing interest in molecular glue degraders, which offer the potential to tackle challenging biological targets. We are excited about their application in immunology and the early progress we have seen by Monte Rosa in this space and with MRT-6160. We look forward to advancing MRT-6160 and learning more about its potential to provide a new therapeutic option for people living with a range of immune-mediated conditions,” said Fiona Marshall, President of Biomedical Research at Novartis. “Novartis is committed to bringing forward new therapeutic options for these patients, and we are happy to be working with Monte Rosa to harness the potential of this approach to address unmet medical needs.”

MRT-6160 is a potent, highly selective, and orally bioavailable investigational degrader of VAV1, a key signaling protein downstream of both the T- and B-cell receptors. Preclinical studies have demonstrated deep degradation of VAV1, resulting in a significant decrease in cytokines linked to immune-mediated conditions, with no detectable effects on other proteins. MRT-6160 has shown promising activity in preclinical models of multiple immune-mediated conditions.

Under the terms of the agreement, Novartis has agreed to pay Monte Rosa $150 million up front. Monte Rosa is eligible to receive up to $2.1 billion in development, regulatory, and sales milestones, beginning upon initiation of Phase 2 studies, as well as tiered royalties on ex-US net sales. Monte Rosa will co-fund any Phase 3 clinical development and will share any profits and losses associated with the manufacturing and commercialization of MRT-6160 in the US. The agreement is subject to customary closing conditions including regulatory clearance. Monte Rosa plans to provide further information regarding its updated cash position and runway in its third quarter 2024 earnings update.

Monte Rosa Therapeutics is a clinical-stage biotechnology company developing highly selective molecular glue degrader (MGD) medicines for patients living with serious diseases in the areas of oncology, autoimmune and inflammatory diseases, and more. MGDs are small molecule protein degraders that have the potential to treat many diseases that other modalities, including other degraders, cannot. Monte Rosa’s QuEEN (Quantitative and Engineered Elimination of Neosubstrates) discovery engine combines AI-guided chemistry, diverse chemical libraries, structural biology and proteomics to identify degradable protein targets and rationally design MGDs with unprecedented selectivity. The QuEEN discovery engine enables access to a wide-ranging and differentiated target space of well-validated biology across multiple therapeutic areas. Monte Rosa has developed the industry’s leading pipeline of MGDs, which spans oncology, autoimmune and inflammatory disease and beyond, and has a strategic collaboration with Roche to discover and develop MGDs against targets in cancer and neurological diseases previously considered impossible to drug.
