Brief Summary:
This phase III trial compares the effect of adding cabozantinib to avelumab versus avelumab alone in treating patients with urothelial cancer that has spread 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 Outcome Measures :
  1. Overall survival (OS) [ Time Frame: Time from randomization until death due to any cause, assessed up to 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.


Secondary Outcome Measures :
  1. Progression free survival (PFS) [ Time Frame: Time from randomization until disease progression as assessed by the treating physician using Response Evaluation Criteria in Solid Tumors (RECIST) or death due to any cause, assessed up to 5 years ]
    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.

  2. Tumor response [ Time Frame: Up to 5 years ]
    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.

  3. Incidence of adverse events (AE) [ Time Frame: Up to 5 years ]
    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.

    • Women of childbearing potential include women who have experienced menarche and who have not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or are not postmenopausal. Post menopause is defined as amenorrhea >= 12 consecutive months. Note: women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, ovarian suppression or any other reversible reason

Patients with previously diagnosed CNS metastases are eligible if they have completed their treatment and have recovered from the acute effects of radiation therapy or surgery prior to randomization, have discontinued corticosteroid treatment for at least 2 weeks, and are neurologically stable. Baseline brain imaging with contrast-enhanced CT or magnetic resonance imaging (MRI) scans for subjects with known brain metastases is required to confirm eligibility
  • No major surgery within 4 weeks prior to randomization. Subjects must have complete wound healing from surgery before randomization. Subjects with clinically relevant ongoing complications from prior surgery are not eligible
  • No palliative radiotherapy within 48 hours prior to patient randomization
  • No hemoptysis of >= 0.5 teaspoon (2.5 mL) of red blood, clinically significant hematuria, hematemesis, coagulopathy, or other history of significant bleeding (e.g. pulmonary hemorrhage) within 3 months before randomization

Note: if initial QTcF is found to be > 500 ms, two additional electrocardiograms(EKGs) separated by at least 3 minutes should be performed. If the average of these three consecutive results for QTcF is =< 500 ms, the subject meets eligibility in this regard.
      • Any history of congenital long QT syndrome.
      • Stroke, transient ischemic attack (TIA), myocardial infarction, or other symptomatic ischemic event or thromboembolic event (e.g., deep venous thrombosis, pulmonary embolism (DVT/PE) within 6 months before randomization.

    • No concomitant anticoagulation with coumarin agents (e.g., warfarin), direct thrombin inhibitors (e.g., dabigatran), direct factor Xa inhibitor betrixaban, or platelet inhibitors (e.g., clopidogrel).

      • Allowed anticoagulants are the following:

        • Prophylactic use of low-dose aspirin for cardio-protection (per local applicable guidelines) and low-dose low molecular weight heparins (LMWH).Therapeutic doses of LMWH or anticoagulation with direct factor Xa inhibitors rivaroxaban, edoxaban, or apixaban in subjects without known brain metastases who are on a stable dose of the anticoagulant for at least 1 week before first dose of study treatment without clinically significant hemorrhagic complications from the anticoagulation regimen or the tumor
  • Physicians should consider whether any of the following may render the patient inappropriate for this protocol:

    • Psychiatric illness which would prevent the patient from giving informed consent.
    • Uncontrolled medical conditions which, in the opinion of the treating physician, would make this protocol unreasonably hazardous for the patient.
    • Patients who cannot swallow oral formulations of the agent(s).

In addition:

  • Women and men of reproductive potential should agree to use an appropriate method of birth control throughout their participation in this study due to the teratogenic potential of the therapy utilized in this trial.

Patients with vitiligo, endocrine deficiencies including hypo or hyper thyroid disease managed with replacement, diabetes type 1 are eligible.
  • Sexually active subjects (men and women) must agree to use medically accepted barrier methods of contraception (e.g., male or female condom) during the study and continue for 4 months after the last dose of study drugs, even if oral contraceptives are also used.
