Evaluating Sovilnesib for Ovarian Cancer Treatment

A Phase 1b Dose Optimization Study of Sovilnesib (an Oral KIF18A Inhibitor) in Subjects with Advanced High Grade Serous Ovarian Cancer

Phase 1 Interventional Volastra Therapeutics, Inc. · NCT06084416

This study is testing a new drug called sovilnesib to see if it can safely help people with a tough type of ovarian cancer that doesn't respond to standard treatments.

What this trial studies

This phase 1b clinical trial investigates the safety, tolerability, pharmacokinetics, and efficacy of sovilnesib in patients with platinum-resistant high grade serous ovarian cancer. The study employs an adaptive multi-cohort design, where participants are randomized to receive different dose levels of the drug. The trial consists of two parts: the first part involves a small group of subjects to gather preliminary data, while the second part expands the participant pool to refine the recommended dose for future studies. The goal is to establish the optimal dose of sovilnesib for treating this challenging cancer type.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with confirmed high grade serous ovarian cancer who are platinum-resistant.

Not a fit: Patients with certain genetic mutations or those who have previously received KIF18A treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with resistant forms of ovarian cancer.

How similar studies have performed: While this approach is novel in the context of KIF18A inhibition for ovarian cancer, similar studies targeting other pathways have shown promise.
