Incyte and AstraZeneca announce new lung cancer trial collaboration

11 January 2016  •  Author: Victoria White

Incyte and AstraZeneca are to evaluate the efficacy and safety of Incyte’s INCB39110 in combination with AstraZeneca’s Tagrisso (osimertinib) as a second-line treatment for patients with EGFR mutation-positive non-small cell lung cancer (NSCLC), who have been treated with a first generation EGFR tyrosine kinase inhibitor (TKI) and subsequently developed the T790M resistance mutation.

INCB39110 is an orally bioavailable, isoform-selective inhibitor of Janus-associated kinase 1 (JAK1) while Tagrisso is a next generation epidermal growth factor receptor (EGFR) inhibitor

There is increasing evidence that signalling through the JAK-STAT (signal transducer and activator of transcription) pathway could be a contributing factor in resistance to EGFR TKI treatment in patients with EGFR mutation NSCLC. Blocking both JAK and EGFR activity may therefore offer an improved targeted treatment benefit in some patients.

Under the terms of the agreement, Incyte and AstraZeneca will collaborate on a Phase 1/2 study, to be conducted by Incyte. The Phase 1 part of the trial is expected to establish a recommended dose regimen for the combination of INCB39110 and Tagrisso while the Phase 2 part of the study will assess the safety and efficacy profile. Results from the study will be used to determine whether further clinical development of this combination is warranted.

Agreement builds on existing collaboration between Incyte and AstraZeneca

Commenting on the collaboration, Rich Levy, MD, Chief Drug Development Officer, Incyte, said, “The expansion of our research collaboration with AstraZeneca will allow us to further our understanding of these two compounds and explore their potential synergies both of which support our goal of delivering innovative medicines that will benefit patients with cancer or other diseases. We look forward to adding to our ongoing clinical research for INCB39110 and exploring the potential of this combination.”

Antoine Yver, head of Oncology, Global Medicines Development at AstraZeneca, added, “We are pleased to be building on our existing relationship with Incyte and exploring a potentially exciting combination for lung cancer patients who have developed a resistance to first generation EGFR inhibitor treatment. This collaboration allows us to explore further ways in which Tagrisso, our first-in-class T790M-directed tyrosine kinase inhibitor, can help meet urgent unmet patient need, following its accelerated approval in the U.S. and the recent positive CHMP opinion, recommending approval in Europe.”

This agreement builds on an existing collaboration between Incyte and AstraZeneca, announced in May 2014, to explore AstraZeneca’s anti-PD-L1 immune checkpoint inhibitor, durvalumab, in combination with Incyte’s oral indoleamine dioxygenase-1 (IDO1) inhibitor, epacadostat (INCB24360).
