"Last year was transformational for Monte Rosa as we continued to build our world-class leadership team, expanded operations across our two sites in Boston and Basel, named MRT-2359 – our development candidate for the GSPT1 program – and secured $377.6 million in funding," said Markus Warmuth, M.D., CEO of Monte Rosa. "As we look to 2022, we anticipate significant pipeline progress, including the submission of our IND for MRT-2359, as well as continued lead optimization on our CDK2 and NEK7 programs. We are also seeing exciting advancements across our proprietary QuEEN platform, including the expansion of our understanding of structural characteristics of degradable proteins driven by both our experimental and AI platforms. We believe we are well-positioned both organizationally and financially to execute on our vision of tackling historically undruggable targets and identifying potent, highly selective therapies for patients with few or no treatment options."

FOURTH QUARTER 2021 & RECENT HIGHLIGHTS

•Presented preclinical data for MRT-2359 demonstrating anti-tumor activity in L- and N-Myc-positive non-small cell lung cancer patient-derived xenograft (PDX) models. The data were featured as part of the company’s presentation at the 40th Annual J.P. Morgan Healthcare Conference. MRT-2359 is a potent, selective and orally bioavailable GSPT1-directed molecular glue degrader. MRT-2359 has been shown to induce tumor regression in multiple Myc-driven preclinical models, including models of non-small cell lung cancer and small cell lung cancer

•Advanced CDK2 degrader program into lead optimization. Leveraging the company’s QuEEN platform, Monte Rosa has identified selective MGDs for CDK2, a highly validated oncogenic driver of breast, gynecological and other cancers

•Announced license and research collaboration agreement with Dr. Nir London and the Yeda Research and Development Company Ltd., the commercial arm of the Weizmann Institute of Science. The goal of the collaboration is to leverage innovative covalent chemistry to further expand the target space for molecular glue degradation

•Strengthened executive leadership team with promotions of Jullian Jones, Ph.D., J.D., MBA, to Chief Business Officer and Phil Nickson, Ph.D., J.D., to General Counsel

•Presented at recent scientific and medical conferences, including:
•3rd Annual Protein Degradation and Targeting Undruggables Congress, March 8-9
•ESMO Targeted Anticancer Therapies Congress 2022, March 7-8
•2nd Annual Targeted Protein Degradation Europe, March 15-17

UPCOMING MILESTONES & DATA PRESENTATIONS

•Submission of Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) for MRT-2359 expected in mid-2022

•Initiation of at least one additional lead optimization program expected in 2022
