Biologics license application submitted for eptinezumab, an anti-CGRP antibody for migraine prevention

February 25, 2019 by Janice Reichert

Alder BioPharmaceuticals has submitted a biologics license application (BLA) for eptinezumab, a humanized IgG1 monoclonal antibody that targets calcitonin gene-related peptide (CGRP), for migraine prevention. If the US Food and Drug Administration grants approval, Alder will be on track to launch the drug in Q1 2020. The BLA included data from the PROMISE 1 and PROMISE 2 studies, which evaluated the effects of eptinezumab in episodic migraine patients (n=888) or chronic migraine patients (n=1,072), respectively.  In PROMISE 1, the primary and key secondary endpoints were met, and the safety and tolerability were similar to placebo, while in PROMISE 2, the primary and all key secondary endpoints were met, and the safety and tolerability was consistent with earlier eptinezumab studies.

Alder announced one-year results from the PROMISE 1 study in June 2018, which indicated that, following the first quarterly infusion, episodic migraine patients treated with 300 mg eptinezumab experienced 4.3 fewer monthly migraine days (MMDs) from a baseline of 8 MMDs, compared to 3.2 fewer MMDs for placebo from baseline (p= 0.0001). At one year after the third and fourth quarterly infusions, patients treated with 300 mg eptinezumab experienced further gains in efficacy, with a reduction of 5.2 fewer MMDs compared to 4.0 fewer MMDs for placebo-treated patients.  In addition, ~31% of episodic migraine patients achieved, on average per month, 100% reduction of migraine days from baseline compared to ~ 21% for placebo. New 6-month results from the PROMISE 2 study were also released in June 2018.  These results indicated that, after the first quarterly infusion, chronic migraine patients dosed with 300 mg of eptinezumab experienced 8.2 fewer MMDs, from a baseline of 16 MMDs, compared to 5.6 fewer MMDs for placebo from baseline (p <.0001). A further reduction in MMDs was seen following a second infusion; 8.8 fewer MMDs for patients dosed with 300 mg compared to 6.2 fewer MMDs for those with placebo. In addition, ~ 21% of chronic migraine patients achieved, on average, 100% reduction of MMDs from baseline compared to 9% for placebo after two quarterly infusions of 300 mg of eptinezumab.

If approved, eptinezumab would become the fourth antibody therapeutic for migraine prevention on the US market, following the approval of erenumab-aooe (Aimovig; Novartis), galcanezumab-gnlm (Emgality; Eli Lilly & Company) and fremanezumab-vfrm (Ajovy; Teva Pharmaceuticals) in 2018.

First approval for fremanezumab-vfrm

September 17, 2018 by Janice Reichert

On September 14, 2018, the U.S. Food and Drug Administration (FDA) approved fremanezumab-vfrm (Ajovy) for the preventive treatment of migraine in adults. The drug may be administered as either 225 mg monthly, or 675 mg quarterly, subcutaneous doses. Fremanezumab-vfrm is a humanized monoclonal antibody that binds to calcitonin gene-related peptide (CGRP), thereby blocking the binding of the ligand to its receptor. The monoclonal antibody erenumab-aooe (Aimovig), which was approved by the FDA in May 2018 for the preventive treatment of migraine in adults, targets CGRP receptor, rather than the ligand. Marketing applications for galcanezumab, another monoclonal antibody that targets CGRP, are undergoing review by FDA and the European Medicines Agency.

The Antibody Society maintains a comprehensive table of approved mAb therapeutics and those in regulatory review in the EU or US. As of September 14, a total of 9 antibody therapeutics had been granted first approvals in either the US or EU in 2018, and marketing applications for another 7 that have not yet been approved in either the EU or US are undergoing review in these regions. Please log in to access the table in either PDF or Excel formats, located in the Members Only section.

First approval for erenumab

May 17, 2018 by Janice Reichert

On May 17, 2018, the U.S. Food and Drug Administration approved erenumab-aooe (Aimovig) for the preventive treatment of migraine in adults. Erenumab is a human monoclonal antibody that targets calcitonin gene-related peptide (CGRP) receptor, thereby blocking the activity of CGRP, which is involved in migraine attacks. The treatment is given by once-monthly subcutaneous injections.

The approval was based on data from three clinical trials that compared erenuman-aooe to placebo. Over 2000 participants were included in the studies. In the first study (STRIVE, NCT02456740), which included 955 participants with a history of episodic migraine, patients administered erenumab-aooe experienced, on average, one to two fewer monthly migraine days than those on placebo over a 6 month period. In the second study (ARISE, NCT02483585), which included 577 patients with a history of episodic migraine, patients administered erenumab-aooe experienced, on average, one fewer migraine day per month than those on placebo over a 3 month period. The third study, which evaluated 667 patients with a history of chronic migraine, patients treated with erenumab-aooe experienced, on average, 2.5 fewer monthly migraine days than those receiving placebo over a three month period.

The Antibody Society maintains a comprehensive table of approved monoclonal antibody therapeutics and those in regulatory review in the EU or US. As of May 17, a total of 4 antibody therapeutics had been granted first approvals in either the US or EU in 2018, and marketing applications for another 10 that have not yet been approved in either the EU or US are undergoing review in these regions.
