Treatment: Add-on effect of adding tamivarotene (AM80) to gemcitabine, cisplatin, and nivolumab combination therapy【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.
