This phase III trial compares the effect of adding cabozantinib to avelumab versus avelumab alone in treating patients with urothelial cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and avelumab together may further shrink the cancer or prevent it from returning/progressing.

PRIMARY OBJECTIVE:

I. To evaluate the effect of cabozantinib S-malate (cabozantinib) in combination with avelumab on overall survival (OS) compared to avelumab alone in patients with metastatic urothelial cancer (mUC) who did not progress during first-line platinum-based chemotherapy therapy, i.e. patients who had complete response (CR), partial response (PR) or stable disease (SD) after completion of first line platinum-based chemotherapy.

SECONDARY OBJECTIVES:

I. To evaluate the effect of cabozantinib in combination with avelumab on progression-free survival (PFS) compared to avelumab alone for maintenance treatment following initial first-line treatment in patients who had a CR, PR or SD upon completion of first-line platinum-based chemotherapy.

II. To evaluate the safety and tolerability of cabozantinib in combination with avelumab in mUC compared to avelumab alone for maintenance treatment following initial first-line treatment in patients who had a CR, PR or SD upon completion of first-line platinum-based chemotherapy.

III. To evaluate activity of cabozantinib in combination with avelumab based on Response Evaluation Criteria in Solid Tumors (RECIST) compared to avelumab alone for maintenance treatment following initial first-line treatment in patients who had a CR, PR or SD upon completion of first-line platinum-based chemotherapy.

IV. Results of the primary analysis will be examined for consistency, while accounting for the stratification factors and/or covariates of baseline quality of life (QOL) and fatigue.

V. To evaluate the activity of cabozantinib in combination with avelumab compared to avelumab alone based on PD-L1 status of patients' tumors.

QUALITY OF LIFE (QOL) OBJECTIVES:

I. To compare quality-adjusted survival between patients randomized to receive cabozantinib and avelumab versus (vs.) avelumab alone using the European Quality of Life Five Dimension Five Level Scale Questionnaire (EQ-5D-5L).

II. To compare patient-reported fatigue as assessed by the Patient Reported Outcomes Measurement Information System (PROMIS)-Fatigue 4a from baseline through 12 months between patients randomized to receive cabozantinib and avelumab vs. avelumab alone.

III. To compare patient-reported global health status/quality of life as assessed by the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-Core (C)30 from baseline through 12 months between patients randomized to receive cabozantinib and avelumab vs. avelumab alone.

IV. To compare scale scores of the EORTC QLQ-Bladder Cancer Muscle-Invasive (BLM)30 (urinary symptoms, urostomy problems, catheter problems, future perspectives, abdominal bloating and flatulence, body image, sexual function) at 3, 6, 12, 18, and 24 months between patients randomized to receive cabozantinib and avelumab vs. avelumab alone.

V. To compare scale scores of the EORTC QLQ-C30 (global health status/quality of life; physical, role, emotional, cognitive, and social function; symptoms) at 3, 6, 12, 18, and 24 months between patients randomized to receive cabozantinib and avelumab vs. avelumab alone.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients receive avelumab intravenously (IV) over 60 minutes on days 1 and 15 of each cycle. Cycles repeat every 28 days for 24 months in the absence of disease progression or unacceptable toxicity. Patients also undergo bone scan at screening and undergo computed tomography (CT) or magnetic resonance imaging (MRI) and biospecimen collection throughout the trial.

ARM B: Patients receive avelumab IV over 60 minutes on days 1 and 15 of each cycle and cabozantinib orally (PO) daily on days 1-28 of each cycle. Cycles repeat every 28 days for 24 months in the absence of disease progression or unacceptable toxicity. Patients also undergo bone scan at screening and undergo CT or MRI and biospecimen collection throughout the trial.

After completion of study treatment, patients are followed every 30 days through 90 days, then every 3 months for 5 years.

Subgroup analyses will be done using a stratified Cox model that includes the treatment arm assignment as an explanatory variable and a separate model will be generated for each level for the subgroup of interest.

A stratified Cox model will be used to compare the outcomes between the two treatment groups. The subgroup analyses will be done using a stratified Cox model that includes the treatment arm assignment as an explanatory variable and a separate model will be generated for each level for the subgroup of interest.

Will be defined as a complete response or partial response (PR) as measured with Immune-Modified RECIST. Will be compared between the arms using a Mantel-Haenszel test (that accounts for the randomization stratification factors) comparing the response rates between the two treatment arms. This analysis will only include patients who had a PR or stable disease (SD) response to first-line therapy. An additional analysis will be conducted using logistic regression analysis that includes treatment arm and any baseline variables that are imbalanced between the arms as explanatory variable.

Will be assessed by Common Terminology Criteria for Adverse Events 5.0. Will be summarized with frequencies and relative frequencies. The maximum grade for an AE will be recorded for each patient by treatment arm. The number (percent) of patients that experience each observed adverse event will be summarized by treatment arm. In addition, the proportion of patients that experience a grade 3+, grade 4+, and grade 5 adverse event will be summarized as the number and percent of patients by treatment arm. The primary summary will be regardless of attribution. Will also do an analogous summary for the adverse events that were deemed at least possibly related to treatment.

This phase II trial studies how well atezolizumab when given with glycosylated recombinant human interleukin-7 (CYT107) works in treating patients with urothelial carcinoma that has spread to nearby tissue or lymph nodes (locally advanced), cannot be removed by surgery (inoperable), or has spread to other places in the body (metastatic). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. CYT107 is a biological product naturally made by the body that may stimulate the immune system to destroy tumor cells. Giving atezolizumab and CYT107 may work better in treating patients with locally advanced, inoperable, or metastatic urothelial carcinoma compared to atezolizumab alone.

PRIMARY OBJECTIVE:

I. To determine the clinical efficacy of the investigational treatment combination.

SECONDARY OBJECTIVES:

I. To determine the clinical activity and toxicity of the investigational treatment combination.

II. The clinical benefit rate (CBR), progression-free survival (PFS), duration of response (DOR), as measured by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and immune-related (ir) RECIST, and overall survival (OS).

III. The CBR, PFS, DOR, and OS in all patients and patients stratified by PD-L1 expression levels in the tumor microenvironment.

IV. The safety and toxicity of addition of CYT107 to atezolizumab.

EXPLORATORY OBJECTIVES:

I. To determine the immune correlates of the clinical activity of the investigational treatment combination.

II. Explore the effect of the investigational treatment combination on the number and phenotype of tumor-specific T cells in the peripheral blood.

III. Investigate for evidence that the investigational treatment combination increases the exposure of bladder cancer-specific antigens (e.g., cancer/testis antigens or neoantigens).

IV. Investigate changes in tumor microenvironment that correlate with response or provide information on potential actionable causes for lack of clinical benefit.

V. Investigate the potential that administration of atezolizumab with CYT107 may perturb the pharmacokinetics and immunogenicity of CYT107.

OUTLINE: Safety Run-in phase - patients assigned to the experimental arm (atezolizumab + CYT107). If the treatment combination of the experimental arm demonstrates an acceptable safety profile in the Safety Run-In (one or fewer patient experiences a protocol-defined Dose Limiting-Toxicity), randomized enrollment into the trial will begin. The Run-in phase patients will be analyzed and reported separately both for safety and for efficacy.

Patients are randomized to 1 of 2 groups.

GROUP 1 (experimental arm): Patients receive CYT107 intramuscularly (IM) on days 1, 8, 15, and 22, and atezolizumab intravenously (IV) over 60 minutes on day 8 of cycle 1. Following cycle 1, patients receive atezolizumab IV over 30-60 minutes on day 1. Cycles with atezolizumab repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) and/or magnetic resonance imaging (MRI) scans, and collection of blood and stool samples on study. Patients may also undergo tumor biopsy at screening and on study.

GROUP 2 (control arm): Patients receive atezolizumab IV over 60 minutes on cycle 1. Following cycle 1, patients receive atezolizumab IV over 30-60 minutes on day 1. Cycles repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Patients also undergo CT and/or MRI scans, and collection of blood and stool samples on study. Patients may also undergo tumor biopsy at screening and on study.

After completion of study treatment, patients are followed up at 30 days and then every 12 weeks for up to 2 years.

Atezolizumab and CYT107 in Treating Participants With Locally Advanced, Inoperable, or Metastatic Urothelial Carcinoma

A Randomized Phase II Study of Atezolizumab (MPDL3280A) Plus Recombinant Human IL7 (CYT107) in Patients With Locally Advanced or Metastatic Urothelial Carcinoma

The evaluation of the effect of the investigation treatment combination on the immune-bias of the tumor microenvironment, based upon baseline and post-baseline tumor biopsy comparisons of number, distribution, and phenotype of tumor-infiltrating cells; PD-L1 expression, and expression of Interferon gamma (IFN-gamma) and associated proinflammatory gene expression in the tumor microenvironment.

ORR to be defined by complete response (CR) or partial response (PR) as measured by Response Evaluation Criteria in Solid Tumors (RECIST) version (v.) 1.1. The Cochran Mantel Haenszel test will be conducted to compare ORR in the experimental arm (atezolizumab + CYT107) to the ORR in the control arm (atezolizumab monotherapy). A one-sided significance level of 0.10 will be considered for the test.

CBR is defined as the percentage of patients with advanced or metastatic cancer who have achieved CR, PR, and stable disease (SD) to a therapeutic intervention in clinical trials of anticancer agents. A two-sided test for a difference in proportions will be conducted to compare the CBR in the experimental arm to the CBR in the control arm. A two-sided significance level of 0.05 will be considered for the test. Will also assess CBR in patients stratified by PD-L1 expression levels in the tumor microenvironment.

PFS to be measured by RECIST v1.1 and irRC. PFS will be summarized using Kaplan-Meier estimates. Long-rank tests will be conducted for overall survival (OS) and PFS to compare between the 2 arms. A one-sided significance level of 0.10 will be considered. Will also assess PFS in patients stratified by PD-L1 expression levels in the tumor microenvironment.

DOR is measured by RECIST v1.1 and irRC. DOR will be summarized using Kaplan-Meier estimates. Long-rank tests will be conducted for OS and PFS to compare between the 2 arms. A one-sided significance level of 0.10 will be considered. Will also assess DOR in patients stratified by PD-L1 expression levels in the tumor microenvironment.

OS will be summarized using Kaplan-Meier estimates. Long-rank tests will be conducted for OS and PFS to compare between the 2 arms. A one-sided significance level of 0.10 will be considered. Will also assess OS in patients stratified by PD-L1 expression levels in the tumor microenvironment.
