BioXcel Therapeutics Announces Submission of IND for Lead Immuno-oncology Candidate, BXCL701, in Treatment Emergent Neuroendocrine Prostate Cancer
First-in-human Phase 1b / 2 combination trial to treat rare form of prostate cancer, tNEPC, using BXCL701 and a PD-1 checkpoint inhibitor
NEW HAVEN, Conn., Oct. 08, 2018 (GLOBE NEWSWIRE) -- 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, today announced it has submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (“FDA”) to evaluate its lead immuno-oncology candidate, BXCL701, in combination with pembrolizumab (Keytruda®) as a potential therapy for treatment emergent neuroendocrine prostate cancer (“tNEPC”). BTI expects to initiate the trial, subject to IND approval, in the fourth quarter of 2018.
BXCL701 is a first in class oral immunotherapy with dual mechanisms of action that has demonstrated single agent activity in melanoma, with an established safety profile from 700 healthy subjects and cancer patients. Designed to stimulate both the innate and acquired immune systems, BXCL701 works by inhibiting dipeptidyl peptidase (DPP) 8/9 and blocking immune evasion by targeting fibroblast activation protein (FAP). Preclinical combination data evaluating BXCL701, a checkpoint inhibitor and other immuno-oncology agents has demonstrated encouraging anti-tumor activity in multiple tumor types and formation of functional immunological memory. BXCL701’s primary mechanism of action has recently been highlighted in multiple peer reviewed journals, providing further validation of the scientific rationale behind BXCL701.
tNEPC is a rare hormone-refractory manifestation of prostate cancer occurring secondary to treatment with androgen deprivation therapies such as Zytiga® (Johnson & Johnson) and Xtandi® (Pfizer). This form of highly aggressive tumor, with no current treatment, is observed in approximately 20-30% of patients treated with androgen inhibitors and has a median survival time of less than one year. Single agent checkpoint inhibitor therapy produces very low response rates in hormone refractory prostate cancer, creating a major unmet medical need for tNEPC patients.
Dr. Vincent J. O’Neill, Senior Vice President and Chief Medical Officer of BTI, commented, “We believe that inhibition of DPP 8/9 and FAP can effectively target tNEPC, a recently characterized form of prostate cancer. We believe the combination of BXCL701 and pembrolizumab can inhibit tumor growth and increase T-cell infiltration, potentially resulting in superior clinical responses. Submission of our IND for BXCL701 marks a significant milestone for BTI, and we look forward to further assessing its potential as a treatment for tNEPC and other forms of cancer. We are excited to initiate the trial of BXCL701 in combination with a checkpoint inhibitor to advance our mission of developing transformative medicines for patients.”
The trial has been designed by BTI’s clinical team, in consultation with its immuno-oncology clinical advisory board. BTI has selected a world-class oncology focused full service clinical research organization (“CRO”) to develop BXCL701 as a combination therapy. The CRO will support BTI in selecting the trial sites as well as conducting and managing the clinical studies.
