About This Trial

【Treatment of Urothelial Carcinoma】 Treatment for urothelial carcinoma includes surgery, chemotherapy (anticancer drugs), and radiation therapy. Chemotherapy is generally used when metastasis has already occurred at diagnosis and surgery is not curative (metastatic urothelial carcinoma) or when the cancer recurs after local therapy such as surgery or radiation therapy (recurrent urothelial carcinoma). Although there are several recommended treatments for urothelial carcinoma, the options are often limited by side effects and other factors, and these treatments may not be fully effective. Therefore, the development of safer and more effective treatments is desired. 【About the Drugs to be Used in this Clinical Trial】 In this clinical trial, the investigational drug MIKE-1 will be used in combination with nivolumab plus GC (cisplatin gemcitabine), one of the recommended chemotherapy regimens, and subsequently with nivolumab monotherapy for patients with unresectable metastatic or recurrent urothelial cancer. Nivolumab, cisplatin, and gemcitabine are injectable (intravenous infusion), while MIKE-1 is oral. 【Purpose of the Clinical Trial】 The purpose of this clinical trial is to evaluate the efficacy (how much the cancer shrinks or slows down) and safety of the investigational drug MIKE-1 in combination with nivolumab and gemcitabine and cisplatin therapy in patients with untreated unresectable or recurrent urothelial cancer.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Urothelial Carcinoma Bladder and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 43 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
