Item 8.01 Other Events.

 

On June 4, 2018, BioXcel Therapeutics, Inc. (the “Company”) issued a press release announcing data from preclinical studies of the Company’s BXCL701 and Nektar Therapeutics’ NKTR-214 as a potential combination therapy for pancreatic cancer patients at the 2018 American Society for Clinical Oncology (ASCO) Annual Meeting, being held June 1-5, 2018 in Chicago, IL.  Results from the preclinical study demonstrate that BXCL701, a dipeptidyl peptidase (DPP) and fibroblast activation protein (FAP) inhibitor, in combination with NKTR-214, a CD122-biased agonist, and an anti-PD-1 antibody represents a new treatment approach against pancreatic cancer. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

BioXcel Therapeutics and Nektar Therapeutics Present Preclinical Pancreatic Cancer Data for BXCL701, NKTR-214 and Anti-PD1 Combination Therapy at ASCO 2018 Annual Meeting

 

BXCL701 in Combination with NKTR-214 and anti-PD-1 Therapy Leads to Complete and Sustained Tumor Regression and Immune Memory in Pre-Clinical Syngeneic Models

 

Results Support Further Development of triplet therapy

 

BRANFORD, Conn., June 4, 2018 — BioXcel Therapeutics, Inc. (“BTI”) (Nasdaq: BTAI), a clinical stage biopharmaceutical development company utilizing novel artificial intelligence to identify the next wave of medicines across neuroscience and immuno-oncology, today announced data from preclinical studies of the Company’s BXCL701 and Nektar Therapeutics’ NKTR-214 as a potential combination therapy for pancreatic cancer patients at the 2018 American Society for Clinical Oncology (ASCO) Annual Meeting, being held June 1-5, 2018 in Chicago, IL.

 

Results from the preclinical study demonstrate that BXCL701, a dipeptidyl peptidase (DPP) and fibroblast activation protein (FAP) inhibitor, in combination with NKTR-214, a CD122-biased agonist, and an anti-PD-1 antibody represents a new treatment approach against pancreatic cancer. BTI plans to present additional data demonstrating BXCL701’s potential to generate anti-cancer immunity.

 

Dr. Vincent J. O’Neill, Chief Medical Officer of BTI commented, “This study highlights the potential of BXCL701 to augment the effect of other immunotherapies such as NKTR-214 and anti-PD-1 to produce an improved, durable anti-cancer response. The triplet therapy leverages the power of both innate and adaptive immunity to attain complete tumor regression in these preclinical studies by recruiting increased levels of immuno-stimulatory cytokines, effector T cells and NK cells while reducing the cytokines involved in immune evasion. Most importantly, the combination also demonstrated functional evidence of memory T cell response, making the mice immune to re-challenge with the same cancer cells. We believe that this triple combination could offer a unique therapeutic approach in the treatment of immune checkpoint inhibitor resistant pancreatic cancer.”

 

DPPs play a crucial role in tumorigenesis and tumor stromal remodelling. FAP is associated with immune system evasion and suppression in cancer biology. High levels of both DPP8/9 and FAP are expressed in pancreatic tumors.  BXCL701’s dual mechanism of action targets DPP8/9, stimulating effector T cells and NK cells while inhibition of FAP helps to clear an immune obstructive tumor microenvironment, thus promoting a robust pro-inflammatory response.

 

NKTR-214 in combination with anti-PD-1 has shown a strong anti-cancer response in multiple murine cancer models and in combination with nivolumab in multiple human cancers(1),(2).

 

This preclinical study aimed to utilize the triple combination of BXCL-701, NKTR-214 and anti-PD-1 to potentiate more robust and durable anti-tumor activity and help overcome an immune refractory tumor microenvironment. Data from the study displayed a significant improvement in complete tumor regression and development of anti-cancer immunity in the Pan02 mouse model. Treatment with the triple combination showed increases in Ly6G+ neutrophils, CD8+ T cell infiltrates and immune stimulatory cytokines that are responsible for generation of memory T cell responses. The combination therapy also achieved a notable reduction in FAP expressing cells and cytokines associated with tumor invasion and migration.
