Danube: This phase III trial is evaluating the safety and effectiveness of an immunotherapy drug (Durvalumab, MEDI4736), when given alone or in combination with standard care chemotherapy or another immunotherapy drug (Tremelimumab), in patients with stage 4 urothelial cancerA Phase III, Randomized, Open-Label, Controlled, Multi-Center, Global Study of First-Line MEDI4736 (Durvalumab) Monotherapy and MEDI4736 (Durvalumab) in Combination With Tremelimumab Versus Standard of Care Chemotherapy in Patients With Unresectable Stage IV Urothelial Cancer

Exclusion

• Prior exposure to immune-mediated therapy, including but not limited to, other anti cytotoxic T-lymphocyte-associated protein 4 (CTLA 4), anti-PD-1, anti-PD-L1, or anti-PD-L2 antibodies, including therapeutic anticancer vaccines. Prior local intervesical chemotherapy or immunotherapy is allowed if completed at least 28 days prior to the initiation of study treatment.
• History of allogenic organ transplantation that requires use of immunosuppressive agents.
• Active or prior documented autoimmune or inflammatory disorders. The following are exceptions to this criterion: • Patients with vitiligo or alopecia • Patients with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement • Any chronic skin condition that does not require systemic therapy • Patients without active disease in the last 3 years may be included but only after consultation with AstraZeneca • Patients with celiac disease controlled by diet alone may be included but only after consultation with AstraZeneca.
• Brain metastases or spinal cord compression unless the patient's condition is stable and off steroids for at least 14 days prior to the start of study treatment. Patients with suspected or known brain metastases at screening should have an MRI (preferred)/CT, preferably with IV contrast to access baseline disease status.
• Active infection including tuberculosis, hepatitis B, hepatitis C, or human immunodeficiency virus (HIV).
• Current or prior use of immunosuppressive medication within 14 days before the first dose of investigational product (IP). The following are exceptions to this criterion: • Intranasal, inhaled, topical steroids, or local steroid injections (eg, intra articular injection) • Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent • Steroids as premedication for hypersensitivity reactions (eg, CT scan premedication).
• Receipt of live attenuated vaccine within 30 days prior to the first dose of IP. Note: Patients, if enrolled, should not receive live vaccine during the study and up to 30 days after the last dose of IP.
