Portage acquires majority interest in Biohaven Pharmaceutical Holding Company Limited

TORONTO, Jan. 6, 2014 /PRNewswire/ - Portage Biotech Inc. ("Portage") (OTCQB: PTGEF, CNSX: PBT.U), is pleased to announce that it has acquired approximately 54% equity in Biohaven Pharmaceutical Holding Company Limited ("Biohaven"), a private corporation formed under the laws of the British Virgin Islands, for $3.5 million, payable as $1.75 million upfront and the balance in three installments over the next eleven months.

Biohaven is engaged in the identification and development of clinical stage neuroscience compounds targeting the glutamatergic system. Biohaven has a worldwide license from Yale University to use intellectual property relating to the use of certain glutamate modulating agents in the treatment of neuropsychiatric disorders. The company's first drug candidate is a glutamate modulating agent being developed for treatment-resistant mood and anxiety disorders.

Biohaven has assembled a team of experts who have extensive experience in the development of therapeutic agents for affective disorders and also comprise the originators at Yale University who discovered the therapeutic potential of glutamate modulation in anxiety and depression. Team members have designed and executed successful development programs testing a variety of agents in affective disorders, leading to first-cycle FDA approvals and successful commercialization of these new drugs in the CNS (central nervous system) area.

"Acquiring majority ownership in Biohaven is an important step for Portage as this represents the second leg of our business model which is to add compelling new products with strong management teams as subsidiaries," commented Dr. Greg Bailey Chairman of Portage.  "Similar to Portage Pharmaceuticals ("PPL"), we plan on identifying additional products for the Biohaven team as we have been working on for Dr. Bruce Littman and Dr. Frank Marcoux who manage PPL. Now we have a remarkable team with track records of success in translational medicine and clinical drug development."

The key members of the Biohaven team include Dr. Declan Doogan who is Executive Chairman of Biohaven and also a CEO of Portage, Dr. Robert Berman who is Chief Medical Officer of Biohaven, and the faculty originators of the licensed Yale intellectual property, Dr. Vlad Coric, Dr. John Krystal and Dr. Gerard Sanacora.

"Biohaven combines experienced pharmaceutical drug developers and skilled academic neuroscientists. Preclinical data and clinical studies performed at Yale, as well as at other academic centers, suggest that the glutamatergic system is a truly viable target for neuropsychiatric drug development," says Dr. Declan Doogan. Dr. Bailey of Portage added, "Biohaven represents a timely opportunity to translate the knowledge and experience gained at Yale about the role of glutamate in neuropsychiatric disorders into advances in the clinic. A novel molecular target with clinical data suggestive of efficacy and the right team to deliver."

Dr. Doogan has over 30 years of drug development experience primarily with Pfizer, where his most recent post was as Senior Vice President and Head of Worldwide Development. He initially joined Pfizer in 1982, where he led the Zoloft clinical development program. Dr. Doogan also served as Interim Chief Executive Officer of Amarin Corporation from October 2009 through August 2010 and was recently Chief Medical Officer. A seasoned drug development executive and life sciences investor, he sits on the Boards of several biotechnology companies. Dr. Doogan received his medical degree from Glasgow University in 1975. He is a Fellow of the Royal College of Physicians and the Faculty of Pharmaceutical Medicine in the UK.

Dr. Berman has over two decades of research experience in affective and cognitive disorders.  Dr. Berman received a BA from Yale University in Molecular Biophysics and Biochemistry and an MD degree from the Mount Sinai School of Medicine.  His academic work at the Yale University School of Medicine is notable for the first study demonstrating the efficacy of ketamine in the treatment of depression.   Dr. Berman has held positions in the pharmaceutical industry over the past 13 years, involved in Phase 1 through Phase 3 studies.  Among his industry accomplishments, Dr. Berman led the registrational program to obtain the first indication with a neuroleptic for the adjunctive treatment of major depressive disorder. He is currently an Adjunct Professor of Psychiatry, Yale University School of Medicine.

Dr. Coric has over 14 years of clinical trial experience first serving as the Chief of Inpatient Services at the Yale Clinical Neuroscience Research Unit and then holding positions in clinical development within the pharmaceutical industry. His academic work at the Yale University School of Medicine along with Drs. Krystal and Sanacora is notable for being the first to report anxiolytic and antidepressant properties associated with certain glutamate modulating agents. Dr. Coric received a BS from the University of Connecticut where he was an Honors Scholar in Physiology and Neurobiology. He earned his medical degree at Wake Forest University School of Medicine and completed his internship, specialty training and fellowship at Yale. Dr. Coric is a Fellow of the American Psychiatric Association and has served as President of the Connecticut Psychiatric Society (a district branch of the American Psychiatric Association).

Dr. Krystal is Chairman of Psychiatry and Robert L. McNeil Jr. Professor of Translational Research at the Yale School of Medicine. He also serves as the Chief of Psychiatry at Yale-New Haven Hospital, Director of the NIAAA Center for the Translational Neuroscience of Alcoholism, and Director of the Clinical Neuroscience Division, VA National Center for PTSD. Dr. Krystal received his BA from the University of Chicago and completed his medical degree as well as residency training at Yale. Dr. Krystal is considered a leading expert in the areas of psychopharmacology, glutamatergic neurotransmission, alcoholism, schizophrenia, and post-traumatic stress disorders.  He is a member of the Institute of Medicine of the National Academy of Sciences, Past-President of the American College of Neuropsychopharmacology, and Editor of Biological Psychiatry (IF=9.25).

Dr. Sanacora is Professor and Director of the Yale Depression Research Clinic. Dr. Sanacora's work is concentrated largely on elucidating the pathophysiological mechanisms associated with mood and other neuropsychiatric disorders.  He completed an NIH sponsored Medical Scientist Training Program at the State University New York at Stony Brook, earning his Ph.D. in Physiology and Biophysics in 1992 and his M.D. degree in 1994. He completed his residency and an NIH funded Neuroimaging Scientist Training Program Fellowship at Yale. Dr. Sanacora's laboratory has provided several seminal studies highlighting the contributions of the glutamatergic neurotransmitter system to the pathophysiology and treatment of mood and anxiety disorders. Reflecting his contributions to the field, he received the Anna-Monkia Stiftung international award for the investigation of the biological substrate and functional disturbances of depression in 2009 and the Joel Elkes Research Award for Outstanding contributions to Psychopharmacology from the ACNP in 2011. Dr. Sanacora was elected a Fellow of the American College of Neuropsychopharmacology in 2012.

About Portage:

Portage is engaged in researching and developing pharmaceutical and biotech products through to clinical "proof of concept" with an initial focus on unmet clinical needs. Following proof of concept, Portage will look to sell or license the products to large pharmaceutical companies for further development and commercialization.

Portage through its subsidiary holds an exclusive worldwide licence in non-oncology fields and the know-how relating to the Antennapedia protein transduction technology developed by Trojantec. Antennapedia ("Antp"), is an unusual protein that allows for the delivery of drugs into a cell and even into the nucleus which is often the desired site of action. This protein coupled with a drug may even cross the blood brain barrier. Portage is developing a research pipeline of Antp-based drug candidates and evaluating their function and potential as new therapeutic agents for a variety of non-oncology indications.

Portage management is looking to in license additional products to add to its portfolio.
