Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals with high-grade serous epithelial ovarian carcinoma who have received one or two prior lines of therapy.
✕Probably not a fit
Patients with low-grade tumors or those who have not received prior treatment may not benefit from this study.

What this trial studies
This Phase 1b open-label, multicenter study investigates the safety and tolerability of ZN-c3 in combination with other chemotherapy agents for patients with advanced ovarian cancer. The study aims to assess the preliminary clinical activity, pharmacokinetics, and pharmacodynamics of the treatment regimen. Eligible participants must have high-grade serous epithelial ovarian carcinoma or related conditions and have previously undergone one or two lines of therapy. The study will be conducted at multiple sites across the United States.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced ovarian cancer.
How similar studies have gone: Other studies have shown promise with similar combination therapies in treating ovarian cancer, suggesting potential for success in this approach.

INCLUSION CRITERIA:
For Part 1:
* Histologically or cytologically confirmed FIGO Stage III/IV high-grade serous or endometrioid ovarian, fallopian tube, or peritoneal carcinoma.
* Subjects must have received 1 or 2 prior therapeutic regimens/lines of therapy in the advanced or metastatic setting. At least one regimen must have contained cisplatin or carboplatin.
* The disease must be platinum resistant (ie, the PFI must have been \< 6 months). Platinum refractory disease (ie, PD during first-line platinum-based therapy) is allowed.

Prior therapy:
• Subjects must have received 6 cycles of platinum-based doublet chemotherapy in the 1L or 2L setting as their most recent therapy
Response to prior platinum therapy:
1. In the 1L setting: Complete Response, Partial Response, or Stable Disease to platinum-based chemotherapy.
2. In the 2L setting:
1. Progressive Disease \>183 days after receiving the last dose of platinum chemotherapy in the 1L setting,
2. Complete Response, Partial Response, or Stable Disease to 2L platinum-based chemotherapy.
* Adequate hematologic, and organ function
For Part 2 Dose Expansion:
* Subjects must have at least 4 cycles of platinum-based chemotherapy in 2L and have Complete Response, Partial Response, or Stable Disease
* Subjects must have progressed while on a PARP inhibitor for 1L maintenance Additional protocol-defined inclusion criteria may apply
EXCLUSION CRITERIA:
* Histology of abdominal adenocarcinoma of unknown origin or diagnosis of a borderline ovarian tumor.
* Subjects with carcinosarcomas (even if there is a serous component)
* A serious illness or medical condition(s)
* Subjects with active (uncontrolled, metastatic) second malignancies or requiring therapy.
