Monte Rosa Therapeutics to Present at 5th Annual Targeted Protein Degradation Summit and 34th EORTC-NCI-AACR Symposium

New and Updated Preclinical Data Highlight Potential of GSPT1-directed Molecular Glue Degrader (MGD) MRT-2359 in the Treatment of MYC-driven Cancers

– Novel and Proprietary AI/Machine Learning Engine Characterizes Protein Surfaces, Expands Insights into Neosubstrate Universe, Reprogrammable Ligases and MGDs

BOSTON, Oct. 20, 2022 (GLOBE NEWSWIRE) — Monte Rosa Therapeutics, Inc. (NASDAQ: GLUE), a biotechnology company developing novel molecular glue degrader (MGD)-based medicines, today announced that new and updated preclinical data for MRT-2359, the company’s lead drug candidate and a potent and selective GSPT1-directed MGD targeting MYC-driven solid tumors, will be presented at the 5th Annual Targeted Protein Degradation Summit, taking place Oct. 25-28 in Boston. The company will also participate in the 34th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Barcelona, from Oct. 26-28.

“At the TPD Summit, we will provide a more comprehensive view of the underlying mechanism of action of MRT-2359 and its ability to effectively degrade GSPT1 and induce anti-tumor activity in MYC-driven cancer models,” said Markus Warmuth, M.D., CEO of Monte Rosa. “With our Phase 1/2 study of MRT-2359 initiating this quarter, we are also excited to continue momentum by sharing the clinical trial design supported by our comprehensive preclinical data package at the Triple Symposium.”

“We are pleased to highlight our proprietary AI and machine learning capabilities for the first time at the TPD Summit,” added John Castle, Ph.D., Chief Data Scientist of Monte Rosa. “Insights from these engines are integral to our target-centric approach and rational design of novel MGDs that show promise preclinically in oncology, immunology, inflammation and beyond.”

About MRT-2359
MRT-2359 is a potent, selective and orally bioavailable molecular glue degrader (MGD) that induces the interaction between the E3 ubiquitin ligase component cereblon (CRBN) and the translation termination factor GSPT1, leading to the targeted degradation of GSPT1 protein. The MYC transcription factors (c‑MYC, L-MYC and N-MYC) are well-established drivers of human cancers that maintain high levels of protein translation, which is critical for uncontrolled cell proliferation and tumor growth. Our preclinical studies have shown that this addiction to MYC-induced protein translation creates a dependency on GSPT1. MRT-2359 exploits this vulnerability by inducing degradation of GSPT1, disrupting protein synthesis preferentially in MYC-driven cell lines and leading to anti-tumor activity in MYC-driven tumor models. A Phase 1/2 clinical study aims to evaluate the safety, tolerability and anti-tumor activity of MRT-2359.

About Monte Rosa
Monte Rosa Therapeutics is a biotechnology company developing a portfolio of novel molecular glue degrader (MGD) medicines. These medicines are designed to employ the body’s natural mechanisms to selectively eliminate therapeutically relevant proteins. The company has developed a proprietary protein degradation platform, called QuEEN™ (Quantitative and Engineered Elimination of Neosubstrates), that enables it to rapidly identify protein targets and MGD drug candidates that are designed to eliminate therapeutically relevant proteins in a highly selective manner. The company’s drug discovery platform combines diverse and proprietary chemical libraries of small molecule protein degraders with in-house proteomics, structural biology, AI/machine learning-based target selection, and computational chemistry capabilities to predict and obtain protein degradation profiles.
