“We are pleased to share initial data from the trial of INCB001158 in MSS colorectal carcinoma that is refractory to standard therapies, a disease that has very low historical average response rates to checkpoint inhibitors such as pembrolizumab,” said Susan Molineaux, PhD, president and chief executive officer of Calithera. “We are pleased with the progress of this program as we seek to develop a first-in-class product for patients with multiple types of solid tumors.”
Calithera and Incyte are collaborating to conduct this Phase 1 study evaluating INCB001158 as monotherapy and in combination with the PD-1 inhibitor pembrolizumab in checkpoint inhibitor refractory and naïve advanced/metastatic solid tumors. Data were presented as of the data cut-off of July 22, 2019. The study was designed as a dose escalation of INCB001158 alone and in combination with pembrolizumab followed by expansion cohorts which followed a Simon 2 Stage design. There were three monotherapy expansion cohorts (non-small cell lung cancer, colorectal carcinoma and other solid tumors) and eight combination expansion cohorts, including PD-(L)1-naïve (MSS colorectal carcinoma, head and neck cancer, gastric cancer, mesothelioma) and PD-(L)1 refractory (non-small cell lung cancer, urothelial carcinoma, melanoma, and MSI colorectal carcinoma) patients.

About INCB001158 (CB-1158)
INCB001158 (CB-1158) is an investigational first-in-class, novel small molecule arginase inhibitor. Arginase is an enzyme that suppresses the immune-mediated destruction of tumors by depleting levels of a key amino acid, L-arginine, from the tumor microenvironment. A number of cell types in the tumor microenvironment, including myeloid-derived suppressor cells, macrophages, and neutrophils, can secrete arginase. L-arginine deprivation can act via nutrient sensor pathways to exert several suppressive effects on T-cell function, inhibiting proliferation, decreasing cytokine production, and diminishing expression of the T-cell receptor CD3ζ chain. Arginase activity may thus impair T-cell mediated anti-tumor responses. INCB001158 is being developed in a global collaboration with Incyte Corporation.
