  Purpose
This is a phase 1/1b open-label, multicenter, dose-selection study of CPI-444, an oral small molecule targeting the adenosine-A2A receptor on T-lymphocytes and other cells of the immune system. This trial will study the safety, tolerability, and anti-tumor activity of CPI-444 as a single agent and in combination with atezolizumab, a PD-L1 inhibitor against various solid tumors. CPI-444 blocks adenosine from binding to the A2A receptor. Adenosine suppresses the anti-tumor activity of T cells and other immune cells.

Condition Intervention Phase
Non-Small Cell Lung Cancer Malignant Melanoma Renal Cell Cancer Triple Negative Breast Cancer Colorectal Cancer Bladder Cancer Metastatic Castration Resistant Prostate Cancer Drug: CPI-444 Drug: CPI-444 + atezolizumab Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1/1b, Open-Label, Multicenter, Repeat-Dose, Dose-Selection Study of CPI-444 as Single Agent and in Combination With Atezolizumab in Patients With Selected Incurable Cancers

Primary Outcome Measures:
  • Incidence of dose-limiting toxicities (DLTs) of CPI-444 as a single agent and in combination with atezolizumab [ Time Frame: 28 days following first administration of CPI-444 ]
  • Objective response rate per RECIST v1.1 criteria of CPI-444 as a single agent and in combination with atezolizumab [ Time Frame: From start of treatment to end of treatment, up to 24 months ]
  • Incidence of treatment-emergent adverse events, as assessed by NCI CTCAE v.4.03, of CPI-444 as a single agent and in combination with atezolizumab [ Time Frame: Continuously, up to 24 months ]
  • Mean and median Area under the curve (AUC) of CPI-444 [ Time Frame: Day 14 of Cycle 1 ]

Detailed Description:
This is a phase 1/1b open-label, multicenter, dose-selection study of CPI-444, an oral small molecule targeting the adenosine-A2A receptor on T-lymphocytes and other cells of the immune system. This trial will study the safety, tolerability, and anti-tumor activity of CPI-444 as a single agent and in combination with atezolizumab, an intravenous PD-L1 inhibitor. CPI-444 blocks adenosine from binding to the A2A receptor. Adenosine suppresses the anti-tumor activity of T cells and other immune cells.
