Full description
Open-label, interventional, multi-centre, randomized phase II study. Cancer studied is non-metastatic muscle invasive bladder cancer (MIBC) Patients (male or female) will receive avelumab every 2 weeks in combination with standard chemotherapy or alone. There are 2 cohorts of patients.
Cohort with patients cisplatin-ineligible will receive either avelumab alone or in combination with paclitaxel-gemcitabine chemotherapy.
Cohort with patients cisplatin-eligible will receive either methotrexate, vinblastine, doxorubicine and cisplatin in combination with avelumab or cisplatin, gemcitabine in combination with avelumab.
The estimated number of subjects to screen is 183 patients for an estimated number of 166 patients enrolled for 150 evaluable patients:
26 patients in the paclitaxel, gemcitabine in combination with avelumab arm (cisplatin-ineligible patients) 26 patients in avelumab alone arm (cisplatin-ineligible patients) 49 patients in cisplatin gemcitabine + avelumab arm (cisplatin-eligible patients) 49 patients in methotrexate, vinblastine, doxorubicine and cisplatin + avelumab arm (cisplatin-eligible patients)
AVELUMAB:
Avelumab will be administered at a dose of 10 milligram per kilogram (mg/kg) 1-hour intravenous (iv) infusion once every 2 weeks. Dose reductions are not allowed.
Depending on the treatment arm, Avelumab will be given associated with chemotherapy or alone for a maximum of 4 administrations.
DD-MVAC:
DD-MVAC consists of Methotrexate 30 mg/m2 iv day 1, Vinblastine 3 mg/m2 iv day 2, Cisplatin 70 mg/m2 iv day 2 and Doxorubicin 30 mg/m2 iv day 2. Each cycle is given every 2 weeks for a maximum of 4 administrations. Pegfilgrastim 6 mg subcutaneous (SQ) 24-48 hours after completion of chemotherapy will be given.
Chemotherapy is associated with Avelumab 10 mg/kg iv given on day 2 every 2 weeks.
CG:
CG consists of Gemcitabine 1000 mg/m2 iv in day 1 and day 8 and Cisplatin 70 mg/m2 iv in day 1. Each cycle is given every 3 weeks for a maximum of 4 administrations. Pegfilgrastim 6 mg subcutaneous (SQ) 24-48 hours after completion of chemotherapy will be given.
Chemotherapy is associated with Avelumab 10 mg/kg iv given on day 1 every 2 weeks.
PG:
PG consists of Paclitaxel 80 mg/m2 iv in day 1 and day 15 and Gemcitabine 1000 mg/m2 iv in day 1 and day 15. Each cycle is repeated every 4 weeks for a maximum of 4 administrations.
Chemotherapy is associated with Avelumab 10 mg/kg i.v. given every on day 1 every 2 weeks.
For patients receiving neoadjuvant chemotherapy treatment, the surgery (cystectomy or nephroureterectomy associated to lymphadenectomy) will be performed within 3-6 weeks after the last administration of neoadjuvant chemotherapy treatment.
For patients receiving avelumab alone, the surgery will be performed 2 weeks (+7 days) after the last administration of avelumab.
Any delay in surgery (> 6 weeks after the last chemotherapy administration or >3 weeks after the last administration of avelumab alone) for any reason, needs to be discussed with the PI/Sponsor.
For all patients, neoadjuvant treatment will be stopped if there is evidence of progression of disease (by RECIST 1.1 or investigator's decision) or unacceptable toxicity according to the investigator. In this situation, the investigator will decide if it is needed to proceed directly with the surgery.
The end of study will be declared when all the following criteria will have been met:

Inclusion and exclusion criteria
General Inclusion Criteria:
Age ≥ 18 years old
Must have histologically confirmed muscle invasive urothelial carcinoma (transitional cell carcinoma) or urothelial carcinoma with mixed histology of the bladder, renal pelvis or ureters. Stage permitted: T2, T3 or T4a. T stage is based on the standard of care transurethral resection of the bladder tumour (TURBT) sample
Patients may have nodal disease (Nx, N0, N1 or N2) at imagery but there must be no evidence of distant metastases (M0)

Be a medically appropriate candidate for surgery as determined by an attending urologist
Adequate bone marrow function as defined below:
Adequate liver function as defined below:
Serum pregnancy test (for subjects of childbearing potential) negative within 7 days prior to study treatment administration.
Women of childbearing potential must agree to use one highly effective method of contraception prior study entry, during the course of the study and up to 6 months after the last administration of study treatment. Men with childbearing potential partner must agree to use condom during the course of this study and up to 6 months after the last administration of the study treatment.
Completion of all necessary screening procedures within 28 days prior to treatment.

Exclusion Criteria:
Subjects meeting one of the following criteria are not eligible for this study:

Systemic corticosteroids at physiologic doses ≤ 10 mg/day of prednisone or equivalent; c. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)

Has received vaccination within 4 weeks of the first dose of avelumab and while on trials is prohibited except for administration of inactivated vaccines such as influenza vaccine.
Is currently participating in or has participated in a study of an investigational agent or using an investigational device within 28 days prior to study registration
History of prior invasive malignancy within 2 years (exception of adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, localised prostate cancer or ductal carcinoma in situ)
Known prior severe hypersensitivity to investigational product or any component in its formulations, including known severe hypersensitivity reactions to monoclonal antibodies (NCI CTCAE v4.03 Grade ≥ 3)
Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrolment), myocardial infarction (< 6 months prior to enrolment), unstable angina, congestive heart failure (≥ New York Heart Association Classification Class II), or serious cardiac arrhythmia requiring medication."
Pregnant and/or lactating women.
Subject with a significant medical, neuro-psychiatric, or surgical condition, currently uncontrolled by treatment, which, in the principal investigator's opinion, may interfere with completion of the study.
Persisting toxicity related to prior therapy (NCI CTCAE v. 4.03 Grade >1); however, alopecia, sensory neuropathy Grade ≤2, or other Grade ≤2 not constituting a safety risk based on investigator's judgment are acceptable.
Other severe acute chronic medical conditions including immune colitis, inflammatory bowel disease, immune pneumonitis, pulmonary fibrosis or psychiatric conditions including recent (within the past year) or active suicidal ideation or behaviour; or laboratory abnormalities that may increase the risk associated with the study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
Exclusion criterion specific for France:
Vulnerable persons according to the article L.1121-6 of the CSP, adults who are the subject of a measure of legal protection or unable to express their consent according to article L.1121-8 of the CSP.
