Effective New Migraine Treatments on the Way

Preventive treatments for migraines are very limited, and it is a critical unmet medical need.

Breakthrough discovery of the role of Calcitonin Gene-Related Peptide (CGRP) in the development of a migraine has created a stir in the migraine research field. CGRP is a neuropeptide whose elevated level plays part in triggering migraine pain.

Nowadays monoclonal antibodies have become an important tool for the development of many novel treatments. These antibodies are made of similar immune cells that recognize and specifically bind to the antigen responsible for the disease and inhibit its function.

Last week, Eli Lilly’s migraine treatment drug, galcanezumab was reported to show promising results in reducing headache in migraine patients in the late-stage clinical study. Galcanezumab is a once-monthly, self-administered injection.

Galcanezumab is a monoclonal antibody that is designed for the prevention of a migraine. It targets and blocks the CGRP receptor that is believed to play the key role in the development of a migraine.

The statistically significant reduction in the number of a monthly migraine headache days was observed compared to those on a dummy treatment. Patients with a chronic migraine on 120 mg dose experienced a reduction of 4.7 days in monthly migraine pains compared to a reduction of only 2.8 days in patients on a dummy treatment.

240 mg dose of galcanezumab reduced 4.6 days of a monthly migraine in patients compared to only 2.8 days in patients on a dummy treatment.

Last year, 70 mg of Amgen/Novartis’ migraine drug, erenumab reduced a monthly migraine headache days of episodic migraine patients in late-stage trials.

Erenumab is a fully human monoclonal antibody specifically designed for the migraine prevention. It is also a CGRP antagonist.

70 mg erenumab reduced 3.2 days of monthly migraine pain in patients, and 140 mg reduced 3.7 days of monthly migraine of patients compared to only 1.8 days reduction in those on a dummy treatment.

This year, Teva’s novel CGRP antagonist, Fremanezumab initiated a late-stage trial in patients having cluster migraines.

Alder Biopharmaceuticals’ lead migraine drug candidate, eptinezumab (anti-CGRP) is being developed as a migraine prevention treatment for patients with chronic and frequent episodic migraine. Currently, the drug is in its late-stage clinical trial.

Till now, the impact of migraines on lives has been underestimated. It affects your capability in work often make you miss work. It declines the family activities and social engagements.

The promising upcoming drugs may help people to enjoy migraine-free days which would assist them to prevent the loss of productivity and social life.
