Phase 1 Study to Evaluate MEDI4736 in Subjects With Myelodysplastic Syndrome

A Phase 1 Study to Evaluate the Safety and Tolerability of MEDI4736 as Monotherapy or in Combination With Tremelimumab With or Without Azacitidine in Subjects With Myelodysplastic Syndrome After Treatment With Hypomethylating Agents

This is a multicenter, open-label, Phase 1 study to assess the safety and antitumor activity of MEDI4736 as Monotherapy or in Combination with Tremelimumab with or without Azacitidine in Subjects with myelodysplastic syndrome after treatment with hypomethylating agents

A dose-escalation and dose-expansion study of MEDI4736 (a monoclonal antibody that targets programmed cell death-1 ligand 1 [PD-L1]) to evaluate the safety, tolerability, PK, IM, and antitumor activity of MEDI4736 as monotherapy or in combination with Tremelimumab with or without Azacitidine in adult patients with myelodysplastic syndrome.

Inclusion Criteria:

Adult male or female subjects with pathologically confirmed MDS who failed to respond, relapsed after an initial response, or were unable to tolerate hypomethylating agents, ECOG performance status of 0 - 2, and adequate organ and marrow function.

Exclusion Criteria:
