First-line Gemcitabine/Cisplatin +/- Avelumab in Locally Advanced or Metastatic Bladder Carcinoma
Stopped: ANSM's refusal to validate ATU requests for avelumab in bladder cancer, Decrease in recruitment, Most investigators would like to offer avelumab for maintenance, Absence of benefit to the chemo-immuno combination (pembro+gem-platinum) in phase III

Plain-language summary
This study will assess efficacy (based on response rate) and safety (based on grade ≥ 3 severe adverse effects) of the combination Gemcitabine Cisplatin (GC) + anti-PD-L1 (avelumab) in first-line treatment for locally advanced or metastatic urothelial bladder cancer patients, after 6 cycles of treatment (or at 18 weeks if less than 6 cycles have been given, or earlier if a second line treatment is needed, before this new anticancer treatment has been started).

. Measurable disease according to RECIST 1.1;

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Efficacy: objective response rate with RECIST 1.1 with GC + avelumab
Timeframe: At the end of cycle 6 (each cycle is 21 days)
2
Safety: proportion of severe toxicity with GC + avelumab
Timeframe: At the end of cycle 6 (each cycle is 21 days)
. At least 3 weeks since the end of prior local intravesical treatment (BCG-therapy or ametycine) with resolution of all treatment-related toxicity to grade ≤1 (NCI CTCAE 4.0);
Exclusion criteria
. Other prior first-line therapy;
. Any concurrent chemotherapy, immunotherapy, biologic or hormonal therapy for cancer treatment; focal radiation therapy less than 14 days prior to the first day of the first cycle;
. Other invasive malignancy within 3 years (except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix or breast); Patient with low risk prostate cancer (defined as Stage T1/T2a, Gleason score ≤ 7 and PSA ≤ 10ng/mL) who are treatment-naïve and undergoing active surveillance are eligible;
. 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;
. Symptomatic central nervous system (CNS) metastases or untreated CNS metastases requiring concurrent treatment;
. Clinically significant (i.e. active) cardiovascular disease: cerebral vascular accident/stroke (\< 6 months prior to enrollment), myocardial infarction (\< 6 months prior to enrollment), unstable angina, congestive heart failure (≥ New York Heart Association Classification Class II), or serious cardiac arrhythmia requiring medication;
