On March 25, 2019 BioXcel Therapeutics, Inc. ("BTI") (BTAI) reported that it has filed a Clinical Trial Application (CTA) with the U.K. health authorities for its lead immuno-oncology asset, BXCL701, an orally-available small molecule immune-modulator with dual mechanisms of action, in combination with pembrolizumab (Keytruda), a checkpoint inhibitor, in tNEPC (Press release, BioXcel Therapeutics, MAR 25, 2019, View Source [SID1234534627]). BTI is a clinical-stage biopharmaceutical development company utilizing novel artificial intelligence approaches to identify the next wave of medicines across neuroscience and immuno-oncology.

Following approval of the CTA, BTI plans to expand the Phase 1b/2 US study of BXCL701 and pembrolizumab in tNEPC to the U.K. Professor Johann de Bono, M.D., Ph.D., of The Royal Marsden NHS Foundation Trust and The Institute of Cancer Research, will serve as Principal Investigator for the European study of BXCL701 in tNEPC. Data from the open-label trial will support the ongoing global clinical development of BXCL701.
Additionally, BioXcel Therapeutics is preparing to file an Investigational New Drug (IND) application with the FDA for a clinical trial evaluating the triple combination of BXCL701, NKTR-214 and avelumab in the treatment of advanced pancreatic cancer.
Dr. Chetan D. Lathia, SVP & Head of Translational Medicine, Clinical Pharmacology and Regulatory Affairs of BTI said, "The filing of the CTA in the U.K., for the BXCL701 combination trial is an important regulatory milestone for BTI. It marks the beginning of our plans for the global development of our lead programs."
Dr. Vimal Mehta, Chief Executive Officer of BTI added, "We remain committed to translating the potential of BXCL701’s novel mechanism of action into therapies that can fundamentally change the lives of cancer patients. The filing of this CTA is the first milestone in the expansion of our footprint into major markets outside the US. We believe that our pancreatic cancer clinical development partnership with Nektar, Pfizer and Merck KGaA, Darmstadt, Germany will also benefit the broader BXCL701 program."
The Company also announced that Professor de Bono has joined its Immuno-oncology Clinical Advisory Board. Professor De Bono is the Regius Professor of Cancer Research and a Professor in Experimental Cancer Medicine at The Institute of Cancer Research and The Royal Marsden NHS Foundation Trust. He is also the Director of the Drug Development Unit, overseeing the Phase I trials, with a particular interest in innovative trial designs, circulating biomarkers and prostate cancer. Additionally, he leads the Prostate Cancer Targeted Therapy Group and the Cancer Biomarkers laboratory team. He has served as chief investigator on trials for multiple approved drugs, including ZYTIGA, JEVTANA and XTANDI.
Professor de Bono is a clinical investigator in the KEYNOTE- 199 trial, a study evaluating Pembrolizumab in docetaxel pre-treated castrate-resistant metastatic prostate cancer patients. He graduated with a medical degree and a postdoctoral degree from University of Glasgow. He also trained in medical oncology and was awarded a master’s degree in cancer sciences from the University of Glasgow. Professor de Bono has received multiple awards including one of the "World’s Most Influential Scientific Minds," the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) award and the Royal Society of Chemistry award.
About BXCL701
BXCL701 is an orally-available systemic innate-immune activator with dual mechanisms of action. It 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 an important validation of the scientific rationale behind BXCL701.
