This phase II trial studies the effect of avelumab, gemcitabine and carboplatin before surgery compared with surgery alone in treating patients with muscle invasive bladder or upper urinary tract cancer who are not able to receive cisplatin therapy. 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. Chemotherapy drugs, such as gemcitabine and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving avelumab together with gemcitabine and carboplatin before surgery may work better in lowering the chance of muscle invasive urinary tract cancer growing or spreading, in patients who cannot receive cisplatin therapy compared to surgery alone.
PRIMARY OBJECTIVE: I. To compare pathologic complete response (pCR, pT0N0) with avelumab plus gemcitabine and carboplatin (AGCa) versus (vs.) no neoadjuvant therapy preceding protocol surgery for muscle-invasive bladder cancer or upper tract urothelial carcinoma (MIBC/UTUC) for participants who are ineligible for cisplatin-based chemotherapy. SECONDARY OBJECTIVES: I. To evaluate toxicities with AGCa, and to compare resectability rates and surgical complications by arm in this population. II. To compare event-free survival (EFS) with AGCa versus no neoadjuvant therapy in this population. III. To compare overall survival (OS) with AGCa versus no neoadjuvant therapy preceding surgery in this population. IV. To compare pathologic complete response (pCR, pT0N0) with avelumab plus gemcitabine and carboplatin (AGCa) vs. no neoadjuvant therapy preceding protocol surgery in the subset of participants who received at least 2 cycles of neoadjuvant therapy in Arm A. BANKING OBJECTIVE: I. To bank tumor tissue, blood, and urine for future correlative genomic, transcriptomic, and proteomic studies to discover molecular signatures associated with pCR and resistance. OUTLINE: Patients are randomized to 1 of 2 arms. ARM A: Patients receive avelumab intravenously (IV) over 60 minutes on day 1. Treatment repeats every 14 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 and carboplatin IV over 30 minutes on day 1. Treatment repeats every 21 days for up 4 in the absence of disease progression or unacceptable toxicity. Within 4-8 weeks after final systemic therapy, patients undergo standard of care surgery. ARM B: Patients undergo standard of care surgery. After completion of study treatment, patients are followed up every 12 weeks for years 1-2, every 6 months for year 3, then annually in years 4-5.

Pathologic Complete Response
Compare pathologic complete response (pCR) between arms. pCR is defined as s absence of all disease in the surgical specimen from radical cystectomy, nephroureterectomy or ureterectomy as determined by the pathologist at the institution. This is determined by a biopsy taken at the time of surgery.
Time frame: Measured once - at the time of surgery
Event-free Survival
Compare event-free survival between arms. Event-free survival is defined as the time from randomization to the first EFS event. For those who do not undergo surgery, event time will be assigned to the date of disease assessment that indicated surgery was no longer indicated or physician decision not to conduct the surgery.
Time frame: From randomization to the first event, assessed up to study closure
Incidence of Adverse Events
Evaluate toxicities on both arms. Number of participants with Grade 3-5 adverse events that are possibly, probably or definitely related to study drug are reported. Measured using CTCAE v5.0.
Time frame: treatment start to 90 days post surgery
Overall Survival
To compare overall survival between arms. Overall survival is defined as time from date of registration to date of death due to any cause or patients last known to be alive are censored at their last contact date.
Time frame: Up to 5 years post-surgery
Pathologic Complete Response - After 2 Cycles
Compare pathologic complete response (pCR) between surgery only arm and participants in the avelumab, gemcitabine, carboplatin, surgery arm who received at least two cycles of treatment. pCR is defined as s absence of all disease in the surgical specimen from radical cystectomy, nephroureterectomy or ureterectomy as determined by the pathologist at the institution. This is determined using a biopsy taken at the time of surgery. This outcome uses a subset of participants in arm A who completed exactly 2 cycles of neoadjuvant treatment.
Time frame: Measured once - at the time of surgery
