Trial ID or NCT#



not recruiting iconNOT RECRUITING


This Phase II, single-arm study is designed to evaluate the effect of atezolizumab treatment in participants with locally advanced or metastatic urothelial bladder cancer. Participants will be enrolled into 1 of 2 cohorts. Cohort 1 will consist of participants who are treatment-naïve and ineligible for cisplatin-containing chemotherapy. The results of Cohort 1 are reported separately (NCT02951767). Cohort 2 (reported here) will contain participants who have progressed during or following a prior platinum-based chemotherapy regimen. Participants in both cohorts will be given a 1200 milligrams (mg) intravenous (IV) dose of atezolizumab on Day 1 of 21-day cycles. Treatment of participants in Cohort 1 will continue until disease progression per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) or unmanageable toxicity. Treatment of participants in Cohort 2 will continue until loss of clinical benefit or unmanageable toxicity.

Eligibility Criteria

Ages Eligible for Study: Older than 18 Years
Sexes Eligible for Study: All
Accepts Healthy Volunteers: No
Inclusion Criteria:
  1. - Histologically or cytologically documented locally advanced or metastatic transitional cell carcinoma of the urothelium (including renal pelvis, ureters, urinary bladder, urethra) - Representative tumor specimens as specified by the protocol - Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 - Life expectancy greater than or equal to (>=) 12 weeks - Measurable disease, as defined by RECIST v1.1 - Adequate hematologic and end organ function Cohort 2-Specific Inclusion Criteria - Disease progression during or following treatment with at least one platinum-containing regimen (e.g., gemcitabine and cisplatin [GC], methotrexate, vinblastine, doxorubicin, and cisplatin [MVAC], CarboGem, etc.) for inoperable locally advanced or metastatic urothelial carcinoma or disease recurrence. - A regimen was defined as participants receiving at least two cycles of a platinum-containing regimen. Participants who had received one cycle of a platinum-containing regimen but discontinued due to Grade 4 hematologic toxicity or Grade 3 or 4 non-hematologic toxicity could also be eligible. - Participants who received prior adjuvant/neoadjuvant chemotherapy and progressed within 12 months of treatment with a platinum-containing adjuvant/neoadjuvant regimen were considered as second-line participants.
Exclusion Criteria:
  1. - Any approved anti-cancer therapy within 3 weeks prior to initiation of study treatment - Treatment with any other investigational agent or participation in another clinical trial with therapeutic intent within 28 days prior to enrollment - Active or untreated central nervous system (CNS) metastases as determined by computed tomography (CT) or magnetic resonance imaging (MRI) evaluation during screening and prior radiographic assessments - Leptomeningeal disease - Uncontrolled tumor-related pain - Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures (once monthly or more frequently) - Uncontrolled hypercalcemia (greater than [>] 1.5 millimoles per liter [mmol/L] ionized calcium or Ca > 12 milligrams per deciliter [mg/dL] or corrected serum calcium > upper limits of normal [ULN]) or symptomatic hypercalcemia requiring continued use of bisphosphonate therapy or denosumab - Malignancies other than urothelial bladder cancer within 5 years prior to Cycle 1, Day 1, with the exception of those with a negligible risk of metastasis or death treated with expected curative outcome or incidental prostate cancer - Pregnant and lactating women - History of autoimmune disease - History of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest CT scan - Serum albumin less than (<) 2.5 grams per deciliter (g/dL) - Positive test for human immunodeficiency virus (HIV) and/or active hepatitis B or hepatitis C or tuberculosis - Severe infections within 4 weeks prior to Cycle 1, Day 1 - Significant cardiovascular disease - Major surgical procedure other than for diagnosis within 28 days prior to Cycle 1, Day 1 - Prior allogeneic stem cell or solid organ transplant - Administration of a live, attenuated vaccine within 4 weeks before Cycle 1, Day 1 - Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that may affect the interpretation of the results or render the patient at high risk from treatment complications - Prior treatment with CD137 agonists or immune checkpoint blockade therapies, including anti-cytotoxic T lymphocyte-associated antigen 4 (anti-CTLA-4), anti-programmed death-1 receptor (anti-PD-1), and anti-programmed death-ligand 1 (anti-PD-L1) therapeutic antibodies
