Rimegepant is a medicinal product that is in clinical development as an oral tablet for acute treatment of migraine in adults. Rimegepant works by blocking a receptor called calcitonin gene-related peptide (CGRP). This receptor plays an important role in migraine pathophysiology. A migraine is usually a moderate or severe headache felt as a throbbing pain on one side of the head. Many people also have symptoms such as nausea, vomiting and increased sensitivity to light or sound. Migraines may be with aura (specific warning signs just before the migraine begins, such as seeing flashing lights), although the most common type is without aura (no specific warning signs). Migraine is a common health condition, affecting around one in every five women and around one in every 15 men.
Rimegepant potentially offers an alternative to current agents, particularly for patients who have contraindications to the use of triptans. This includes patients with underlying cardiovascular diseases, or who either do not respond or have inadequate or inconsistent response to triptans or are intolerant to them.
Tanezumab is in clinical development for the treatment of moderate to severe chronic pain associated with osteoarthritis and chronic low back pain. Pain is an unpleasant sensory experience associated with damage to body tissues due to an injury, physical pressure, or inflammation of some part of the body. Chronic pain is persistent or recurrent and lasts for longer than 12 weeks. Moderate pain interferes significantly with daily living activities, and severe pain is disabling and causes an inability to perform daily living activities. Effective long-term treatment options for managing moderate to severe chronic pain are limited. Currently available pain medicines like opioids and analgesics may increase the risks of addiction, gastrointestinal, cardiovascular and renal problems.
