Volastra Therapeutics

Clinical-stage biopharma developing CIN-targeting cancer drugs

Overview

Volastra Therapeutics develops cancer therapies focused on chromosomal instability (CIN), a feature present in many tumors and linked to aggressive disease. Its core strategy is discovering and developing drugs that inhibit KIF18A, a protein essential for cancer-cell division, with two lead programs in Phase I/II for KIF18A inhibitors such as VLS-1488. The company advances drug candidates through clinical trials and aims to bring them to patients with aggressive cancers, building its pipeline through ongoing preclinical work and data sharing from conferences like AACR. Compared with competitors, Volastra combines a CIN-targeted approach with KIF18A inhibition to address tumors characterized by chromosomal instability, seeking to translate preclinical findings into clinically tested therapies. The goal is to provide effective treatments for patients with CIN-associated cancers and to progress multiple candidates through development toward commercialization."

Volastra Therapeutics Announces First Patient Dosed In Phase Ib Clinical Trial Of Sovilnesib

NEW YORK--(BUSINESS WIRE)--Volastra Therapeutics, a clinical-stage biotechnology company, today announced it has dosed the first patient in its Phase Ib clinical trial evaluating sovilnesib in patients with platinum-resistant or refractory high-grade serous ovarian cancer (HGSOC). This trial (NCT06084416) is a randomized dose optimization study of once-daily oral sovilnesib at different dose levels to establish the recommended Phase 2 dose. Sovilnesib was granted Fast Track designation in this indication by the U.S. Food and Drug Administration (FDA) based on its initial clinical data as well as the high unmet need in this population. Volastra in-licensed sovilnesib (formerly AMG-650) from Amgen in February 2023. The company is also progressing its internally developed KIF18A inhibitor, VLS-1488, in an ongoing Phase 1 clinical trial (NCT05902988)
