“Heptares’ technologies and know-how provided unique structural insights concerning the interaction between CGRP and its receptor, enabling the design of a portfolio of differentiated, potent and selective small molecule CGRP antagonist candidates. The joint project activities of both companies have led to the selection and progression through preclinical development of HTL0022562 as the preferred candidate,” commented Dr. Malcolm Weir, Chief R&D Officer of Sosei. “Thanks to this excellent work by the combined teams under the alliance, and following the return of the assets, we are now well positioned to rapidly progress HTL0022562 into the clinic as part of our wholly-owned pipeline. HTL0022562 has very interesting and differentiated properties compared to other small molecule and antibody antagonists, and we look forward to continuing its development.”
“Sosei is extremely pleased to regain worldwide rights for the development and commercialization of HTL0022562 and the CGRP program,” said Peter Bains, CEO of Sosei. “It provides Sosei with another high-quality preclinical candidate to add to our expanding wholly-owned development pipeline. With c.$280 million of cash on balance sheet1, we are well positioned to take this candidate forward and capture greater value for our shareholders.”

About CGRP Antagonists for Migraine and Other Severe Headaches
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 of the brain 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.
