| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
The primary objective is to assess Overall Survival with sacituzumab govitecan in comparison with treatment of physician’s choice
(TPC) in subjects with metastatic or locally advanced unresectable UC. |
|
| E.2.2 | Secondary objectives of the trial |
1. To assess PFS with sacituzumab govitecan in comparison with TPC by investigator assessment and blinded independent central review (BICR) using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
2. To assess ORR, clinical benefit rate (CBR), and duration of objective tumor response (DOR) with sacituzumab govitecan in comparison with TPC by investigator assessment and BICR using RECIST v1.1
3. To assess safety and tolerability of sacituzumab govitecan in comparison with TPC
4. To assess Quality of Life (QOL) with sacituzumab govitecan in comparison with TPC |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
1. Female or male subjects, ≥ 18 years of age, able to understand and give written informed consent.
2. Subjects with histologically documented metastatic or locally advanced unresectable UC defined as:
• Tumor (T) 4b, any node (N) or
• Any T, N 2-3
Tumors of upper and lower urinary tract are permitted. Mixed histologic types are allowed if urothelial is the predominant histology.
3. ECOG PS score of 0 or 1.
4. Subjects with progression or recurrence following receipt of platinum-containing regimen and anti PD-1/PD-L1 therapy for metastatic or locally advanced unresectable disease will be enrolled.
a. Subjects with recurrence or progression ≤ 12 months following completion of cisplatin-containing chemotherapy given in the neoadjuvant/ adjuvant setting may utilize that line of therapy to be eligible for the study. The 12-month period is counted from completion of surgical intervention or platinum therapy, respectively. These subjects must receive anti PD-1/PD-L1 therapy in the metastatic or locally advanced unresectable setting to be eligible.
b. Subjects who received either carboplatin or anti PD-1/PD-L1 therapy in the neoadjuvant/ adjuvant setting will not be able to count that line of therapy towards eligibility for the study.
c. Cisplatin ineligible subjects who meet one of the below criteria and who were treated with carboplatin in the metastatic or locally advanced unresectable settings may count that line of therapy towards eligibility. They must then have received anti PD-1/PDL1
therapy in metastatic or locally advanced unresectable setting to be eligible for the study.
Cisplatin ineligibility is defined as meeting one of the following criteria:
1. Creatinine Clearance <60 mL/min
2. Grade ≥2 Audiometric Hearing Loss
3. Grade ≥2 Peripheral Neuropathy
4. New York Heart Association (NYHA) Class III heart failure
5. ECOG PS ≥2
d. Anti PD-1/PD-L1 therapy administered as part of maintenance therapy may be counted towards eligibility for the study
e. Subjects who received only concurrent chemoradiation for bladder preservation without further systemic therapy are not eligible to enroll in the study. The substitution of carboplatin for cisplatin does not constitute a new regimen provided no new chemotherapeutic agents were added to the regimen and no progression was noted prior to the change in platinum.
5. Subjects with previously treated brain metastases may participate in the study provided they have stable CNS disease for at least 4 weeks prior to the first dose of study drug and stabilization of all neurologic symptoms, have no evidence of new or enlarging brain metastases, and are not using steroids > 20 mg of prednisone (or equivalent) daily for brain metastases for at least 7 days prior to first dose of the study drug.
6. Adequate hematologic counts without transfusion or growth factor support within 1 week of study drug initiation (hemoglobin ≥ 9 g/dL, absolute neutrophil count [ANC] ≥ 1,500/mm3, and platelets ≥ 100,000/μL).
7. Adequate hepatic function (bilirubin ≤ 1.5x institutional upper limit of normal [IULN], aspartate aminotransferase [AST] and alanine aminotransferase [ALT] ≤ 2.5 x IULN or ≤ 5 x IULN if known liver metastases and serum albumin > 3 g/dL).
Docetaxel will only be an option in TPC arm for subjects with a total bilirubin ≤ 1 x IULN, and an AST and/or ALT ≤ 1.5x IULN if alkaline phosphatase is also > 2.5 x IULN.
8. Creatinine clearance ≥ 30 mL/min as assessed by the Cockcroft-Gault equation or other validated instruments (e.g. Modification of Diet in Renal Disease [MDRD] equation. |
|
| E.4 | Principal exclusion criteria |
- Have had a prior anti-cancer mAb/ADC within 4 weeks prior to C1D1 or have had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to C1D1. Subjects participating in observational studies are eligible.
- Have received prior chemotherapy for urothelial cancer with all available SOC therapies in the control arm (i.e., both prior paclitaxel and docetaxel in regions where vinflunine is not an approved therapy, or prior paclitaxel, docetaxel and vinflunine in regions where vinflunine is an approved therapy).
- Have not recovered (i.e., ≤ Grade 1) from AEs due to previously administered chemotherapeutic agent.
• Note: Subjects with ≤ Grade 2 neuropathy or any grade of alopecia are an exception to this criterion and will qualify for the study.
• Note: If subjects received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study therapy.
- Have previously received topoisomerase 1 inhibitors.
- Have an active second malignancy.
• Note: Subjects with a history of malignancy that have been completely treated and with no evidence of active cancer for 3 years prior to enrollment, or subjects with surgically cured tumors with low risk of recurrence are allowed to enroll in the study after discussion with the medical monitor.
- Have an active serious infection requiring anti-infective therapy (Contact medical monitor for clarification).
- Have inability to tolerate or are allergic to any potential TPC agent or sacituzumab govitecan or unable or unwilling to receive the doses specified in the protocol. |
