E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The study is a Phase 3 to demonstrate the benefit of maintenance treatment with avelumab plus Best Standard Care (BSC) vs. BSC alone in prolonging overall survival (OS) in patients with unresectable locally advanced or metastatic urothelial cancer (UC) whose disease did not progress on or following completion of first-line platinum-containing chemotherapy in each co-primary UC patient population: 1) patients determined to have PD-L1-positive tumors (including infiltrating immune cells) by a verified GMP PD-L1 IHC test, and 2) all randomized patients. |
|
E.2.2 | Secondary objectives of the trial |
To compare the progression-free survival (PFS) of avelumab plus BSC vs. BSC alone in each of the co-primary UC patient populations treated with avelumab; To evaluate the anti-tumor activity of avelumab plus BSC and BSC alone according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 in each of the co-primary UC patient populations treated with avelumab; To evaluate the overall safety profile of avelumab plus BSC and BSC alone; To evaluate the PK of avelumab in each of the co-primary UC patient populations treated with avelumab; To assess the immunogenicity of avelumab in each of the co-primary UC patient populations treated with avelumab; To evaluate candidate predictive biomarkers of sensitivity or resistance to avelumab in pre-treatment tumor tissue in each of the co-primary UC patient populations treated with avelumab; To evaluate the effect of avelumab plus BSC and BSC alone on patient-reported outcomes (PROs) in each of the co-primary UC patient populations. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Histological diagnosis of confirmed, unresectable locally advanced or metastatic transitional cell carcinoma of the urothelium. Patients with documented Stage IV disease (per American Joint Committee on cancer/International Union for Cancer Control Tumor Node Metastasis (TNM) system 7th edition) at the start of first-line chemotherapy and measurable disease prior to the start of first-line chemotherapy by RECIST v1.1. 2. Prior first-line chemotherapy must have consisted of at least 4 cycles and no more than 6 cycles of gemcitabine + cisplatin and/or gemcitabine + carboplatin. No other chemotherapy regimens are allowed in this study. The last dose of first-line chemotherapy must have been received no less than 4 weeks, and no more than 10 weeks, prior to randomization; 3. Patients without progressive disease as per RECIST v1.1 guidelines (ie, with an ongoing CR, PR, or SD) following completion of 4 to 6 cycles of first-line chemotherapy. Eligibility based on this criterion will be determined by investigator review of pre-chemotherapy and postchemotherapy radiological assessments (CT/MRI scans); 4. Provision of a recent formalin-fixed, paraffin-embedded (FFPE) tumor tissue block (subsection thereof) from the most recent primary or metastatic tumor biopsy or resection obtained prior to treatment with first line chemotherapy but within 24 months prior to randomization, with no intervening systemic anti-cancer therapy. If a FFPE tissue block cannot be provided, 15 freshly cut unstained slides (10 minimum) will be acceptable. Tumor tissue from cytologic sampling (eg, fine needle aspiration, including FFPE cell pellet material) or bone metastases are not acceptable and should not be submitted; 5. Evidence of a signed and dated informed consent document indicating that the patient (or a legally acceptable representative, as allowed by local guideline/practice) has been informed of all pertinent aspects of the study; 6. Patients who are willing and able to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures; 7. Age above 18 years; 8. Estimated life expectancy of at least 3 months; 9. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1; 10. Adequate bone marrow, renal and liver function; 11. Negative serum pregnancy test at screening (for females of childbearing potential); 12. Female patients able to have children must agree to use a highly effective method of contraception throughout the study and for at least 30 days after the last dose of assigned treatment. |
|

Prior immunotherapy with IL-2, IFN-α, or an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or CTLA-4 antibody (including ipilimumab), or any other antibody or drug specifically targeting T-cell co-stimulation or immune checkpoint pathways; 4. Major surgery within 4 weeks or major radiation therapy within 2 weeks prior to randomization. Prior palliative radiotherapy is permitted, provided it has been completed at least 48 hours prior to patient randomization; 5. Patients with known symptomatic central nervous system (CNS) metastases requiring steroids. 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 these metastases for at least 4 weeks, and are neurologically stable; 6. Persisting toxicity related to prior therapy NCI CTCAE v4.0 Grade >1; however, alopecia, sensory neuropathy Grade <= 2 is acceptable, or other Grade <=2 adverse eventsnot constituting a safety risk based on the investigator's judgment are acceptable; 7. Diagnosis of any other malignancy within 5 years prior to randomization, except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ of the breast or of the cervix, or lowgrade (Gleason 6 or below) prostate cancer on surveillance without any plans for treatment intervention (eg, surgery, radiation, or castration), or prostate cancer that has been adequately treated with prostatectomy or radiotherapy and currently with no evidence of disease or symptoms; 8. Participation in other studies involving investigational drug(s) within 4 weeks prior to randomization. Observational studies are permitted; 9. Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent. Patients with diabetes type I, vitiligo, psoriasis, or hypo- or hyperthyroid disease not requiring immunosuppressive treatment are eligible; 10. Clinically significant (ie, active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), unstable angina, congestive heart failure, or serious cardiac arrhythmia requiring medication; 11.
