BioXcel Therapeutics Expands Immuno-Oncology Partnership with Nektar into Clinical Development in Pancreatic Cancer

Clinical partnership to develop triple combination of BioXcel Therapeutics’ BXCL701, Nektar’s NKTR-214 and a checkpoint inhibitor

NEW HAVEN, Conn; September 24, 2018-- BioXcel Therapeutics, Inc. (“BTI”) (Nasdaq: BTAI), a clinical stage biopharmaceutical development company utilizing novel artificial intelligence approaches to identify the next wave of medicines across neuroscience and immuno-oncology, and Nektar Therapeutics (Nasdaq: NKTR) announced today that the companies are expanding their ongoing research collaboration into a new clinical partnership. The collaboration will clinically evaluate the novel combination of BTI’s BXCL701, a small molecule immune-modulator, DPP 8/9 and FAP inhibitor; Nektar’s NKTR-214, a CD122-biased agonist; and a checkpoint inhibitor as a potential therapy for pancreatic cancer.

Under the terms of the expanded collaboration agreement, BTI will be responsible for initiating and managing the clinical program. The primary objectives of the study are to evaluate safety and efficacy of the triplet combination of BXCL701, NKTR-214 and a checkpoint inhibitor for the treatment of patients with unresectable or metastatic pancreatic cancer. Additionally, correlative immune activation markers will also be evaluated in blood and tumor tissue.

“We are excited to expand our collaboration with Nektar to initiate a clinical program for this novel triplet combination regimen,” said Vimal Mehta, Chief Executive Officer of BTI. “Mechanistically, we believe the action of BXCL701 on macrophages and neutrophils within the tumor tissue can activate the innate immune system and then in combination with NKTR-214 and an anti-PD1, we can then prime adaptive immune cells in order to trigger T-cell driven anti-cancer activity and the generation of T-cell memory. The exciting preclinical data presented at this year’s ASCO Meeting highlighted the complementary mechanisms by which these three agents can synergize to generate durable responses in various animal models.”

“We believe it is essential to target multiple dimensions of the immune system in parallel in order to address the multi-faceted etiologies underlying cancer cell growth in difficult-to-treat tumors such as pancreatic cancer,” said Jonathan Zalevsky, Senior Vice President, Biology & Preclinical Development of Nektar Therapeutics. “This experimental triplet combination regimen of BXCL701, NKTR-214 and a checkpoint inhibitor is designed to leverage multiple mechanisms of action at once to better fight pancreatic cancer while potentially generating long-term cancer immunity. We’re pleased to be working with BTI on this program.”

BTI and Nektar Therapeutics initially announced a preclinical research collaboration in November 2017. This collaboration focused on utilizing the complementary mechanisms of BXCL701 and NKTR-214 to stimulate the body’s own immune system to overcome immunosuppressive mechanisms in the tumor microenvironment.
