Preclinical candidate CGRP antagonist selected for advancement as potential migraine treatment

LONDON and TOKYO, May 18, 2017 /PRNewswire/ --

Heptares Therapeutics ("Heptares"),

a wholly owned subsidiary of Sosei Group Corporation ("Sosei"; TSE Mothers Index: 4565), has been notified by its partner Teva that a preclinical candidate calcitonin gene-related peptide (CGRP) antagonist has been nominated for advancement into further preclinical studies as an investigational treatment for migraine.

Nomination of this small-molecule candidate, discovered by Heptares using its structure-based design approach in partnership with Teva, has triggered a US$5 million payment from Teva to Heptares under the terms of their licensing and drug-discovery agreement signed in 2015. The nominated compound emerged from a rigorous Teva candidate selection process and has a highly differentiated profile from other investigational small-molecule CGRP antagonists, representing the first milestone in a partnership to generate novel candidates for the treatment of episodic and chronic migraine.

"Teva is looking to build a sustainable leadership position in the treatment of migraine and headache," said Ralph Laufer, Teva R&D's Head of Discovery and Product Development unit. "This candidate has very interesting properties. While we still have a long way to go, we do see some characteristics in this molecule that could set it apart within the class, and look forward to continuing its development."

"The discovery work conducted by Heptares and Teva has benefited from our combined expertise in the mechanism of CGRP in migraine. In particular, the unique structural insight we have gained concerning the interaction between CGRP and its receptor, a G protein-coupled receptor, has enabled the selection of a differentiated and highly selective small-molecule candidate," commented Malcolm Weir, CEO of Heptares and Chief R&D Officer of Sosei.

Dr. Weir added, "Blocking the activity of CGRP is viewed increasingly as an attractive approach to treating migraine both acutely and preventatively, with several anti-CGRP antibodies in late-stage clinical trials. Small-molecule CGRP antagonists present a significant opportunity to address migraine even more effectively."

Notes to Editors 

About CGRP Antagonists for Migraine 

Calcitonin gene-related peptide (CGRP) is released during migraine attacks and can trigger migraine in patients. CGRP is found in small to medium-sized neurons in the trigeminal ganglion and mediates its activity through G protein-coupled receptors located throughout the body. Elevated levels of CGRP are found in people with migraine during an attack and blocking CGRP activity is a validated mechanism of action for relieving pain, and also for preventing migraine.

About Migraine 

Approximately 36 million people in the United States and 8 million people in Japan suffer from migraine. Migraine is three times more common in women than in men and affects more than 10 percent of people worldwide. Migraine is defined as recurring attacks of moderate to severe headache pain, typically one-sided, throbbing and worse with activity. The International Headache Society defines chronic migraine as more than 15 headache days per month over a three-month period of which more than eight are migraine, in the absence of medication over use. Episodic migraine is the other migraine sub-type, which is defined as less than 15 headache days per month. During migraine, people can experience varying characteristics such as being very sensitive to light and sound or experiencing nausea and vomiting. There is no absolute cure for migraine since its pathophysiology has yet to be fully understood.

About Heptares Therapeutics 

Heptares is a clinical-stage company creating transformative medicines targeting G protein-coupled receptors (GPCRs), a superfamily of 375 receptors linked to a wide range of human diseases. Heptares' proprietary StaRŪ technology and structure-based drug design (SBDD) capabilities enable us to engineer and develop drugs for highly validated, yet historically undruggable or challenging GPCRs. Using this approach, we are building an exciting pipeline of new medicines (small molecules and biologics) with the potential to transform the treatment of Alzheimer's disease, schizophrenia, cancer immune-oncology, migraine, addiction, metabolic disease and other indications. We have partnerships for our novel candidates and technologies with leading pharmaceutical and biotechnology companies, including Allergan, AstraZeneca, Daiichi Sankyo, Kymab, MedImmune, MorphoSys, Pfizer and Teva.
