Remix Therapeutics Launches with $81 Million Financing to Develop Small Molecule Therapies Designed to Reprogram RNA Processing

Cambridge, Massachusetts. (December 8, 2020) – Remix Therapeutics, a biotechnology company developing small molecule therapies designed to reprogram RNA processing to address the underlying drivers of disease, launched today with $81 million in financing. The funds will support development of the company’s REMaster technology platform and advancement of a pipeline of RNA processing targeted therapeutics. The Series A round was led by Foresite Capital with participation from seed investors Atlas Venture and The Column Group. Additional investors joining the financing included Arch Venture and Alexandria Venture Investments.

“As we reach the limits of what is easily druggable with protein targeting therapies, reprogramming RNA processing represents an exciting new therapeutic opportunity. We believe we can precisely target the cellular complexes that process RNA to address the underlying drivers of disease, working upstream of protein expression,” said Pete Smith, PhD, Co-Founder, President and CSO of Remix Therapeutics and Atlas Venture Entrepreneur in Residence. “Backed by world-class investors, a distinguished board of directors and experts in the field, the Remix team is united in its singular focus to deliver new and better ways to treat disease, especially those with limited treatment options.”

While protein dysfunction is often the direct cause of disease, the root of that dysfunction often begins in a person’s genetic code with changes in DNA and subsequent RNA expression. Remix is designing medicines that target RNA processing to fine-tune how new RNA sequences are produced. These are small molecule therapies designed to be taken orally, allowing for therapeutic modulation throughout the body, including the central nervous system (CNS). Targeting RNA processing has the potential to address a broad range of diseases, including cancers, CNS diseases, rare diseases, and more.

“Remix is harnessing advances in data science, structural biology and chemistry to tackle disease in new and exciting ways,” said Michael Rome, PhD, Managing Director of Foresite Capital. “We believe the company is well-positioned to realize the potential of targeting RNA processing to deliver real therapeutic solutions for patients.”

Fueled by its proprietary REMaster technology platform, Remix is leveraging the power of data analytics, bespoke high-throughput screening technologies, and next generation chemistry to advance a pipeline of breakthrough therapies. The company’s innovative approach has the unique ability to precisely identify and target RNA processing steps to enhance or eliminate protein function, or to correct dysregulation in disease.

“RNA has long been considered a prime therapeutic target, but its innate complexities have made it notoriously difficult to drug. By focusing on RNA processing, the Remix team has identified a compelling way to pursue previously undruggable disease targets,” said Kevin Bitterman, PhD, Chairman of the Board of Remix Therapeutics and Partner at Atlas Venture.

Remix’s Board of Directors include:

· Kevin Bitterman, PhD, Chair of Remix Therapeutics, and Partner at Atlas Venture

· Michael Rome, PhD, Managing Director of Foresite Capital

· Leon Chen, PhD, Partner at The Column Group

· Scott Biller, PhD, Independent Board Member
