Detailed Description
This is an open-label, Phase 1 study with a dose expansion cohort, conducted in two separate disease groups (ovarian and endometrial cancer). The primary objective of the study is to determine the optimal dose of sacituzumab govitecan for use in combination with cisplatin for treatment of epithelial ovarian and endometrial cancers.
For each disease group, there will be a safety run-in phase utilizing a 3+3 design with a de-escalated dose level if the starting dose shows toxicity and an expansion cohort to evaluate the preliminary efficacy and tolerability of the experimental regimen. The dose expansion cohort will consist of 14 patients in the ovarian cohort and 12 patients in the endometrial cohort with an additional 2 patients in each cohort to account for potential patient replacement. This will yield a total sample size of 22-28 patients in the ovarian cancer cohort and a total sample size of 20-26 patients in the endometrial cancer cohort.
Phase 1, Safety Run-in with Dose De-escalation Scheme:
Dose Level 0, starting level: Sacituzumab govitecan 10 mg/kg + Cisplatin 70 mg/m2 IV Dose -1: Sacituzumab govitecan 7.5 mg/kg + Cisplatin 70 mg/m2 IV In this stage, a minimum of 6 patients and a maximum of 12 patients will be required.
The recommended dose expansion cohort (DEC) dose is defined as the highest dose at which no more than 1 out of 6 patients experience a Dose-Limiting Toxicity (DLT)
Phase 2, Dose Expansion Cohort:
Sacituzumab govitecan 7.5-10 mg/kg IV (depending on phase I result) + Cisplatin 70 mg/m2 IV.
Drug product administration will continue until PD, unacceptable toxicity, or death.
The DEC is designed to indicate proof of concept regarding the overall response rate (ORR) and safety of the combination of sacituzumab with cisplatin at the dose established in the safety run-in phase of the study. Once the recommended DEC dose for sacituzumab and cisplatin combination has been established for each disease cohort, an additional 14 patients will be enrolled for the ovarian group and and 12 patients for the endometrial group. An additional 2 patients will be added to each cohort to account for potential patient replacement for a total of 42-54 evaluable patients.

- Serum albumin > 3 g/dL
- Creatinine clearance ≥ 50 mL/min per the Cockcroft-Gault equation
Women of child-bearing potential must agree to use adequate contraception prior to study entry, for the duration of study participation, and for 90 days following completion of therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:
- Has not undergone a hysterectomy or bilateral oophorectomy; or
- Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).
Ability to understand and the willingness to sign a written informed consent.
Exclusion Criteria:
Treatment with any of the following:
- Any investigational agents or study drugs from a previous clinical study within 28 days of the first dose of study treatment
- Any other chemotherapy, immunotherapy or anticancer agents within 14 days of the first dose of study treatment
- Major surgery (excluding placement of vascular access) within 4 weeks of the first dose of study treatment
- Radiotherapy with a wide field of radiation within 4 weeks or radiotherapy with a limited field of radiation for palliation within 2 weeks of the first dose of study treatment
- With the exception of alopecia, any unresolved toxicities from prior therapy greater than Common Terminology Criteria for Adverse Events (CTCAE) grade 1 at the time of starting study treatment
- As judged by the investigator, any evidence of severe or uncontrolled systemic diseases, including active bleeding diatheses, or uncontrolled infection including hepatitis B, hepatitis C and human immunodeficiency virus (HIV). Screening for chronic conditions is not required.
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to sacituzumab govitecan, cisplatin or irinotecan.
- Peripheral neuropathy grade 2 or greater
- Refractory nausea and vomiting, chronic gastrointestinal diseases
- Patients must not be pregnant or nursing due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants.
- Women of childbearing potential unwilling to use effective contraception during study until conclusion of 4-week post-treatment evaluation period
- Known history of unstable angina, MI, or CHF present within 6 months of randomization or clinically significant cardiac arrhythmia (other than stable atrial fibrillation) requiring anti-arrhythmia therapy
- Known history of clinically significant active COPD, or other moderate-to-severe chronic respiratory illness present within 6 months of enrollment.
- Prior history of clinically significant bleeding, intestinal obstruction, or GI perforation within 6 months of enrollment.
- Other concurrent medical or psychiatric conditions that, in the Investigator's opinion, may be likely to confound study interpretation or prevent completion of study procedures and follow-up examinations.
- Prior therapy with sacituzumab govitecan, irinotecan, or any topoisomerase I-containing antibody-drug conjugates at any time for early stage disease
- Have active chronic inflammatory bowel disease (ulcerative colitis, Crohn's disease) or GI perforation within 6 months of enrollment.

Measure Description |
Time Frame |
---|---|---|
Dose-limiting toxicity (DLT) for the Safety Run-In Phase
Time Frame: within the first cycle of therapy (each cycle = 21 days)
|
Safety Run-In Phase: Dose-limiting toxicity (DLT) and the recommended Dose Expansion Cohort (DEC) dose of sacituzumab govitecan in combination with a fixed schedule of cisplatin in patients with ovarian and endometrial cancers. DLT is defined as any therapy-attributable adverse event (AE) requiring discontinuation of therapy within one cycle of combined therapy; specifically grade 3 or 4 non-hematologic toxicity and grade 4 hematologic toxicity events. These will be assessed via NCI's CTCAE v 5.0 toxicity criteria. DEC dose is defined as the highest dose at which no more than 1 out of 6 patients experience a DLT. |
within the first cycle of therapy (each cycle = 21 days)
|
Dose limiting toxicity (DLT) for the DEC Phase
Time Frame: within 1 cycle of therapy (each cycle = 21 days)
|
Dose Expansion Cohort Phase: DLT is defined as any therapy-attributable adverse event (AE) requiring discontinuation of therapy within one cycle of combined therapy; specifically grade 3 or 4 non-hematologic toxicity and grade 4 hematologic toxicity events.
These will be assessed via NCI's CTCAE v 5.0 toxicity criteria.
The DLT rate for the DEC cohort is define as the proportion of patients in the safety population and DEC phase of the study that experience at least 1 DLT within the first cycle of sacituzumab in combination with cisplatin treated at the maximum tolerated dose (MTD)
|
within 1 cycle of therapy (each cycle = 21 days)
|
Overall Response Rate (ORR)
Time Frame: every 3 cycles (each cycle is 21 days)
|
Overall Response Rate ORR will be measured by the percentage of patients whose cancer decreases in size on assessment. This will be measured as the sum of complete response and partial response by RECISIT 1.1 criteria. |
