A Phase 2 Study of Check Point Inhibitor, Durvalumab (Medi4736) for Bacillus Calmette-Guérin (BCG) Refractory Urothelial Carcinoma in Situ (CIS) of the Bladder
The purpose of this study is to test if an experimental drug called Durvalumab (Medi4736) given by intravenous (IV) infusion is effective in treating carcinoma in situ (CIS) of the bladder that no longer responds to Bacillus Calmette-Guérin (BCG) and to collect information on the safety of these drugs and whether they cause any side effects.
• Must have pathologically confirmed urothelial carcinoma in situ (CIS) of the bladder that meet one of the following criteria: 1. Persistence of high-grade CIS at 6 months following an adequate course of BCG; OR - 2. Stage/grade progression at 3 months after induction BCG; OR - 3. Recurrence of high-grade CIS after achieving a disease-free state (i.e., CR) following induction of an adequate course of BCG that occurs \< 9 months after the last exposure to BCG; OR - 4. Persistent CIS noted on the bladder biopsies within 3 months of completing at least 2 induction BCG (minimum of five weekly instillations). An adequate course of BCG should be defined as at least one course of induction (minimum of five weekly instillations) and one maintenance (two of three instillations) in a 6 months period, with an exception for any patient with grade/stage progression after induction BCG (minimum of five weekly instillations).
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
• Adequate organ and marrow function.
• Written informed consent and any locally required authorization (e.g., HIPAA in the USA, EU Data Privacy Directive in the EU) obtained from the subject prior to performing any protocol-related procedures, including screening evaluations.
• Females must not be pregnant, or breast feeding and must have a negative urine or serum pregnancy test within 28 days prior to treatment on day 1. Females of childbearing potential who are sexually active with a nonsterilized male partner must use a highly effective method of contraception from the time of screening, and must agree to continue using such precautions for 90 days after the final dose of Durvalumab. They must also refrain from egg cell donation for 90 days after the final dose of Durvalumab.
• Nonsterilized males who are sexually active with a female partner of childbearing potential must use a highly effective method of contraception and refrain from sperm donation from Day 1 through 90 days after receipt of the final dose of Durvalumab.
