Is this trial a fit for you?

Likely a good fit

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

Probably not a fit

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

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

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