Vividion Therapeutics and Roche Jointly Publish Landmark Nature Paper on Clinical-Stage Covalent Allosteric Inhibitor of Werner Helicase (WRN)  

  • VVD-133214 (also known as RO7589831), a promising drug candidate for patients with MSI-high cancers, is currently being evaluated in a Roche-sponsored Phase 1 first-in-human trial

SAN DIEGO – April 24, 2024– Vividion Therapeutics, Inc., a biopharmaceutical company utilizing novel discovery technologies to unlock high-value, traditionally undruggable targets with precision therapeutics for devastating cancers and immune disorders, today announced a landmark publication in Nature. The publication, “Chemoproteomic Discovery of a Covalent Allosteric Inhibitor of WRN Helicase,” by Kristen Baltgalvis et al, published jointly with our partner Roche, speaks to the chemical proteomic-enabled discovery of a clinical-stage, covalent allosteric inhibitor of Werner helicase (WRN), VVD-133214 (RO7589831), and further confirms Vividion’s approach to discovering and developing novel therapeutics.

“Vividion discovered covalent ligands targeting a novel allosteric pocket on WRN, a well-known but challenging therapeutic target in drug development. The discovery of this allosteric pocket, early ligands and the lead series were directly enabled by Vividion’s innovative approach to drug discovery, including our chemoproteomics platform and unique covalent fragment library,” said Matt Patricelli, Ph.D., Chief Scientific Officer of Vividion.

WRN is a highly sought after synthetic lethal target for cancers with microsatellite instability (MSI), a genetic state resulting from mutations in DNA damage response pathway genes. MSI is most common in colorectal, endometrial and stomach cancers. The WRN molecule was identified under the collaboration agreement entered between Vividion and Roche in 2020. Roche is currently investigating VVD-133214, also known as RO7589831, in a Phase 1 clinical trial (NCT06004245).

“It has been a privilege partnering with Vividion on this significant oncology target, harnessing their leading platform capabilities, and successfully progressing an exceptional molecule into clinical trials within three years from its inception,” said Chris Claiborne, Ph.D., Head, Small Molecule Research and Head of Cancer Cell Targeted Therapy, Roche pharma Research and Early Development (pRED).

“The publication of Vividion’s allosteric WRN inhibitor in Nature and being one of the first to the clinic on such a challenging target, highlights the ability of Vividion’s covalent chemoproteomic platform to identify and advance druggable vulnerabilities on historically challenging targets,” said Ben Cravatt, Ph.D., Scientific Founder of Vividion.
