Is this trial a fit for you?

Likely a good fit

Adults with histologically confirmed advanced/metastatic ovarian or endometrial cancer that is platinum-resistant and who have measurable disease.

Probably not a fit

Patients who do not respond to ARR-002 or who experience safety issues that preclude continued treatment may not benefit.

What this trial studies

This is an open-label, multicenter, phase 1a/1b trial that uses a dose-escalation and expansion design to evaluate ARR-002. The study will assess safety, tolerability, pharmacokinetics, immunogenicity, and preliminary anti-tumor activity in adults with locally advanced or metastatic ovarian or endometrial cancer. Phase 1a focuses on escalating doses in platinum-resistant ovarian cancer, while phase 1b expands cohorts by cancer type (PROC and endometrial cancer). Eligibility includes confirmed disease, measurable lesions, ECOG 0-1, adequate organ function, and agreement to contraception for those of reproductive potential. Exclusion includes prior auristatin-derived drug exposure and recent antitumor therapy.

Why it matters

Potential benefit: If successful, ARR-002 could provide a new option with potential anti-tumor activity for patients with advanced ovarian or endometrial cancer who have limited standard therapies.

How similar studies have gone: Prior studies in similar targeted or antibody–drug conjugate approaches have shown safety signals and hints of anti-tumor activity in gynecologic cancers, but ARR-002 is being evaluated in this specific setting for the first time in this protocol.
