Official Title  ICMJE A Phase Ib/II Open-label, Multi-center Study of the Safety and Efficacy of IMCgp100 in Combination With Durvalumab (MEDI4736) or Tremelimumab or the Combination of Durvalumab and Tremelimumab in Patients With Advanced Melanoma
Brief Summary

This study is a Phase Ib/II, multi-center, open-label study of IMCgp100 as a single agent and in combination with durvalumab (MEDI4736) and/or tremelimumab in metastatic cutaneous melanoma. The purpose of this study is to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and anti-tumor activity of IMCgp100 in combination with durvalumab (MEDI4736, programmed death-ligand 1 [PD-L1] inhibitor), tremelimumab (CLTA-4 inhibitor), and the combination of durvalumab with tremelimumab compared to single-agent IMCgp100 alone. The study will enroll patients who have metastatic melanoma that is refractory to treatment with an anti-PD-1 inhibitor in the metastatic setting.

Recent biologic evidence indicates that optimal responses to programmed cell death-1 (PD-1) directed therapy require the presence of CD8+ T cells in the tumor microenvironment and thus therapies such as IMCgp100 that recruit these effector cells to the tumor may overcome pre-existing resistance to checkpoint blockade. This emerging biology of checkpoint inhibitor resistance suggests the combination of IMCgp100 with checkpoint inhibition may have enhanced activity in patients with pre-existing resistance.

Highly effective methods include the following:

    • Total abstinence from sexual relations for the duration of the treatment when applicable to the lifestyle of the patient. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception
