Fremont, CA: Biotechnology firm developing small molecules to degrade disease-related proteins, Monte Rosa Therapeutics secured USD 32.5 million in a Series A funding round from founding investor Versant Ventures and New Enterprise Associates. Monte Rosa was launched from Ridgeline, Versant's Discovery Engine, based in the Basel Technology Park. The company is currently headquartered in Boston, MA, with research operations in both Boston and Basel, Switzerland.
"With our improved understanding of the broad potential of cereblon and other ubiquitin ligases, there is now an opportunity to eliminate major - and currently undruggable - drivers of solid tumors such as transcription factors and adaptor proteins," said Markus Warmuth, MD, CEO of Monte Rosa and a venture partner at Versant. The company recently developed a platform to rationally design small molecules that reprogram ubiquitin ligases to eliminate disease drivers previously deemed undruggable. The platform holds computational capabilities to predict and model ligase-neosubstrate interactions and quantitative proteomics to obtain protein degradation profiles.

"Unlike protacs, these small molecules can degrade proteins that lack classical drug-binding pockets, which include known drivers of certain forms of cancer and other serious diseases." Monte Rosa Therapeutics was established in 2018 in Versant's Ridgeline laboratories in collaboration with The Institute of Cancer Research (ICR) and Cancer Research UK. Academic co-founders Rajesh Chopra, MD, and Ian Collins, Ph.D., are prominent leaders in the field of protein degradation.
In addition to the investment round, Nicolas Thoma, Ph.D., a world-leading chemical and structural biologist at the Friedrich Miescher Institute in Basel, joined Monte Rosa as a scientific advisor. Thoma recently published a series of seminal papers revealing mechanistic details of cereblon-mediated protein degradation. His work demonstrated the pivotal role of a glycine loop degron on target proteins and opened up the potential for drug discovery on many more disease-relevant targets. This work underpins Monte Rosa's platform and approach. The company is soon to launch a Series B financing to back the development of multiple clinical-stage programs. To capture the full potential of its technology platform, Monte Rosa also will explore discovery-stage pharma collaborations.
