Clinical Trial Summary

This is an open-label, Phase 1/2a, dose-finding study with an initial phase 1 portion, articulated in four separate treatment arms, followed by a dedicated phase 2 for qualifying treatment Arm(s). The primary objective of the Phase 1 portion is to determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of the combinations of: Durvalumab, oral 5-azacitidine, and romidepsin (Arm A); durvalumab, pralatrexate, and romidepsin (Arm B); durvalumab and romidepsin (Arm C); or durvalumab and oral 5-azacitidine (Arm D), in patients with peripheral T-cell lymphoma (PTCL). The safety and toxicity profile of these combinations will be evaluated throughout the entire study. If one or more of the combinations in Arms A, B, C, or D are found to be feasible and an MTD is established, the phase 2 portion of the study will be initiated for the combination(s) with the strongest efficacy signal provided acceptable toxicity.

Description:

The peripheral T-cell lymphomas (PTCL) are a heterogeneous group of aggressive lymphoid neoplasms and account for 10-15% of all newly diagnosed cases of non-Hodgkin's lymphoma (NHL). The current prevalence of PTCL in the United States is estimated to be approximately 9,500 patient. Treatment options for patients with relapsed/refractory (R/R) PTCL have been limited. This study focuses on exploring rational combinations of these T-cell active agents in an effort to develop novel treatment platforms.

Intervention

Drug:
• Durvalumab
Durvalumab is an investigational human monoclonal antibody that works to inhibit (block) a protein called programmed cell death-1 ligand 1 (PD-L1). Durvalumab has not been approved by the FDA for the treatment of PTCL but has been given to patients other types of cancers. Given intravenously (through the vein). Starting dose: 1500 mg
• Pralatrexate
Pralatrexate is an antimetabolite drug. Pralatrexate alone is FDA-approved for the treatment of PTCL. Given intravenously (through the vein). Starting dose: 25 mg/m2
• Romidepsin
Romidepsin is another type of chemotherapy known as histone deacetylase (HDAC) inhibitors. Romidepsin has not been approved for use in lymphoma other than Cutaneous T cell lymphoma (CTCL) by the FDA. Given intravenously (through the vein). Starting dose: 12 mg/m2
• 5-Azacitidine
Oral 5-azacitidine is used for the treatment of myelodysplastic syndrome and acute myeloid leukemia. Azacitidine prevents the body from making DNA and RNA that cells need to grow. This stops the growth of cancer cells and causes them to die. Given by mouth (orally). Starting dose: 300 mg daily
