FDA approves eptinezumab-jjmr for preventative treatment of migraine

by

H. Lundbeck A/S has announced that Vyepti™ (eptinezumab-jjmr) was approved by the U.S. Food and Drug Administration for the preventive treatment of migraine in adults and will be available in April 2020. The recommended dosage is 100 mg as an intravenous infusion over approximately 30 minutes every 3 months; some patients may benefit from a dosage of 300 mg. Lundbeck expects to submit eptinezumab for approval to regulatory authorities in the European Union during 2020, followed by submissions for approval in other regions. Development of eptinezumab was initiated by Alder BioPharmaceuticals, Inc., which was acquired by Lundbeck in October 2019.

Eptinezumab-jjmr is a humanized immunoglobulin G1 (IgG1) monoclonal antibody specific for calcitonin gene-related peptide (CGRP) ligand. It is produced in Pichia pastoris yeast cells by recombinant DNA technology. The safety of VYEPTI was evaluated in over 2000 patients with migraine who received at least one dose of the drug. The approval was supported by positive results from the PROMISE 1 (NCT02559895) and PROMISE 2 (NCT02974153) Phase 3 clinical trials, which investigated eptinezumab for episodic and chronic migraine prevention, respectively. In PROMISE-1, a total of 665 patients were randomized to receive placebo (N=222), 100 mg Vyepti (N=221), or 300 mg Vyepti (N=222) every 3 months for 12 months. Mean migraine frequency at baseline was approximately 8.6 migraine days per month and was similar across treatment groups; mean change from baseline in monthly migraine days (MMD) with Vyepti compared with placebo months 1-3 was -3.9 days for 100 mg (p=0.018), -4.3 days for 300 mg (p<0.001), and -3.2 days for placebo. In PROMISE-2, a total of 1,072 patients were randomized to receive placebo (N=366), 100 mg Vyepti (N=356) or 300 mg Vyepti (N=350) every 3 months for 6 months. Mean migraine frequency at baseline was approximately 16.1 migraine days per month and was similar across treatment groups. Mean change from baseline in MMD compared with placebo months 1-3 was -7.7 days for 100 mg (p<0.001), -8.2 days for 300 mg (p<0.001), and -5.6 days for placebo

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

by

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.
