ARRY-382 / CSF1R

Target: CSF1R | Indication: Cancer

Program Description

In July 2016, Array initiated a Phase 1/2 dose escalation immuno-oncology trial of ARRY-382 in combination with pembrolizumab (Keytruda®), a Programmed Cell Death Receptor 1 (PD-1) antibody, in patients with advanced solid tumors. ARRY-382 is a wholly-owned, potent, highly selective, small-molecule inhibitor of CSF-1R kinase activity.

The study will enroll up to 18 patients with selected advanced solid tumors to determine the maximum tolerated dose and/or recommended Phase 2 dose of the combination. In addition, the safety profile,  pharmacodynamic effects, and preliminary assessment of activity of the combination will be assessed. With appropriate results, Array has the option to advance the combination into expansion cohorts of patients with metastatic melanoma or advanced non-small cell lung cancer (NSCLC).

Results from a prior Phase 1 study designed to assess the safety, pharmacokinetics and pharmacodynamics of ARRY-382 for treating patients with cancer have been presented and a dose and schedule that demonstrates target engagement based on multiple pharmacodynamic biomarkers was identified for further study.
