Purpose
This is an international, multi-center, open-label, phase II study in patients with
metastatic urothelial cancer after failure of platinum-based regimen or anti-PD-1 /PD-L1
based immunotherapy.
At least 321 patients are anticipated to be enrolled across approximately 40 sites from North
America and Europe.
Detailed Description
This is an international, multi-center, open-label, phase II study in patients with
metastatic urothelial cancer after failure of platinum-based regimen and/or anti-PD-1 / PD-L1
based immunotherapy.
The primary objective is Objective Response Rate (ORR) based on central review.
The secondary objectives for Cohorts 1 and 2 are Duration of Response (DOR) and Progression
Free Survival (PFS) both based on central review and Overall Survival (OS).
The secondary objectives for Cohort 3 are Duration of Response (DOR),Clinical Benefit Rate
(CBR), and Progression Free Survival (PFS) based on central review by Response Evaluation
Criteria in Solid Tumors (RECIST) 1.1 criteria; Duration of Response (DOR),Clinical Benefit
Rate (CBR), and Progression Free Survival (PFS) based on central review for Immune-based
therapeutics (iRECIST) criteria, Overall Survival (OS), safety and tolerability of IMMU-132
in combination with pembrolizumab.
Cohort 4:
- DOR, CBR, and PFS based on central review by RECIST 1.1 criteria
- ORR, DOR, CBR, PFS based on investigator review by RECIST 1.1 criteria
- OS
- Safety and tolerability of sacituzumab govitecan in combination with cisplatin
Cohort 5:
- DOR, CBR, and PFS based on central review by RECIST 1.1 criteria
- ORR, DOR, CBR, and PFS based on investigator review by RECIST 1.1 criteria
- OS
- Safety and tolerability of sacituzumab govitecan in combination with cisplatin and
avelumab

Cohort 1 and Cohort 2 | Experimental | All subjects will receive sacituzumab govitecan (IMMU-132) 10 mg/kg intravenously on Days 1 and 8 of a 21 day cycle.
Cohort 1: Subjects with urothelial cancers, after platinum-based regimen (cisplatin or carboplatin) and anti-PD-1/anti-PD-L1 based therapy.
Cohort 2: Subjects in second line therapy of urothelial cancers, ineligible for platinum-based therapy and anti-PD-1/anti-PD-L1 based therapies failure. | |
Cohort 3 | Experimental | All subjects in Cohort 3 will receive sacituzumab govitecan (IMMU-132) 10 mg/kg intravenously on Days 1 and 8 of a 21 day cycle followed by pembrolizumab at the standard approved dose (200 mg) only on Day 1 of a 21 day cycle.
Subjects who have had progression or recurrence of urothelial cancer following a platinum-containing regimen in the metastatic setting, or progression or recurrence of urothelial cancer within 12 months of completion of platinum-based therapy as neoadjuvant or adjuvant therapy. | |
Cohort 4 | Experimental | All subjects will first receive cisplatin (either at 70 mg/m2 on Day 1 of a 21-day cycle or at a split dose of 35 mg/m2 on Days 1 and 8 of a 21-day cycle with a maximum body surface area of 2) followed by sacituzumab govitecan on Days 1 and 8 of a 21-day cycle for up to 6 cycles. If premature termination of 1 agent occurs due to toxicity the other agent may be continued to complete up to 6 cycles of therapy. For subjects who have not progressed, maintenance therapy will begin with infusions of avelumab (800 mg every 2 weeks beginning on Cycle 1, Day 1 and every 2 weeks thereafter) followed by sacituzumab govitecan on Days 1 and 8 every 21 days. | |
Cohort 5 | Experimental | All subjects will first receive cisplatin (either at 70 mg/m2 on Day 1 of a 21-day cycle or at a split dose of 35 mg/m2 on Days 1 and 8 of a 21-day cycle with a maximum body surface area of 2), followed by sacituzumab govitecan on Days 1 and 8 of a 21-day cycle, and avelumab (800 mg every 2 weeks beginning on Cycle 1, Day 1 and every 2 weeks thereafter) for up to 6 cycles. If premature termination of 1 agent occurs due to toxicity the other agents may be continued to complete up to 6 cycles of therapy. For subjects who have not progressed, maintenance therapy will begin with 800 mg of avelumab every 2 weeks followed by infusions of sacituzumab govitecan on Days 1 and 8 every 21 days. | |
Eligibility Criteria
Inclusion Criteria:
- Patients with histologically confirmed urothelial cancer.
- ECOG Performance status score of 0 or 1.
- Cohort 1: Have had progression or recurrence of urothelial cancer following receipt of
platinum-containing regimen (cisplatin or carboplatin):
1. Received a first-line platinum-containing regimen in the metastatic setting or

2. Or received neo/adjuvant platinum-containing therapy for localized
muscle-invasive urothelial cancer, with recurrence/progression ≤12 months
following completion of therapy.
- Cohort 1: In addition to above criterion, have had progression or recurrence of
urothelial cancer following receipt of an anti-PD-1 /PD-L1 therapy.
- Cohort 2: Were ineligible for platinum-based therapy for first line metastatic disease
and have had progression or recurrence of urothelial cancer after a first-line therapy
for metastatic disease with anti-PD-1/PD-L1 therapy. Subject may not have received any
platinum for treatment of recurrent, metastatic or advanced disease.
