AstraZeneca has enlisted the aid of Incyte to try to boost its ambitions in a category of lung cancer immunotherapy where it has a lead over competitors.
The two companies have agreed to pair Incyte’s IDO inhibitor epacadostat with AZ’s PD-L1 inhibitor Imfinzi in a phase 3 trial—due to get underway next year—as a second-line treatment for patients with locally advanced non-small cell lung cancer (NSCLC) that isn’t treatable with surgery and whose disease has not progressed following platinum-based chemoradiation therapy. The phase 3 trial, which will be co-funded by the two companies and carried out by AZ, is expected to start enrolling patients in the first half of 2018, say the partners.
