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

First approval for teprotumumab-trbw (Tepezza)

by

On January 21, 2020, the U.S. Food and Drug Administration (FDA) approved Tepezza (teprotumumab-trbw) for the treatment of adults with thyroid eye disease, which is associated with an outward bulging of the eye that can cause eye pain, double vision, light sensitivity or difficulty closing the eye. Teprotumumab, a human IgG1 antibody targeting insulin growth factor 1 receptor, was granted Fast Track, Breakthrough Therapy and Orphan Drug designations by the FDA. Positive data from both Phase 2 (NCT01868997) and Phase 3 (OPTIC, NCT03298867) studies were reported by Horizon Pharma. In the randomized, placebo-controlled OPTIC study, teprotumumab met the study’s primary endpoint, which was a responder rate of ≥ 2 mm reduction of proptosis (bulging) in the study eye (without deterioration in the fellow eye) at Week 24. Data from the OPTIC study showed that 82.9% of patients receiving teprotumumab were proptosis responders compared to 9.5% of patients receiving placebo at Week 24 (p<0.001). All secondary endpoints in the study were also met.

Crizanlizumab-tmca (Adakveo) approved by FDA

by

On November 15, 2019, the U.S. Food and Drug Administration approved crizanlizumab-tmca (Adakveo) as a treatment to reduce the frequency of vaso-occlusive crisis (VOC), which occurs when blood circulation is obstructed by sickled red blood cells, for patients age 16 years and older. Crizanlizumab is a humanized antibody directed against P-selectin, which contributes to the pathogenesis of sickle cell disease, including vaso-occlusive events and hemolytic anemia. Crizanlizumab was granted Orphan Drug designation in the US and European Union for the treatment of VOC in patients with sickle cell disease, as well as FDA’s Breakthrough Therapy designation for prevention of VOCs in patients of all genotypes with sickle cell disease. A marketing application for crizanlizumab is undergoing review by the European Medicines Agency.

FDA’s approval was based on Phase 2 results from the SUSTAIN study (NCT01895361), which demonstrated that crizanlizumab provided significant benefit over placebo, such as:  1) the percentage of crizanlizumab-treated patients (5 mg/kg) who did not experience any vaso-occlusive crisis (VOC) was higher compared to those treated with placebo (36% vs 17%, P=0.010); 2) 45% reduction in the median annual rate of VOCs leading to health care visits in patients with or without hydroxyurea therapy compared to placebo (1.63 vs 2.98, P=0.010); 3) 42% reduction in median annual rate of days hospitalized versus placebo (4.00 vs 6.87 P=0.45), and 4) A three-fold longer median time to first VOC vs placebo (4.07 vs 1.38 months, P< 0.001).

FDA approves brolucizumab-dbll (BEOVU®)

by

On October 7, 2019, the US Food and Drug Administration (FDA) approved brolucizumab-dbll (BEOVU®) for the treatment of neovascular age-related macular degeneration (nAMD). Brolucizumab is a humanized antibody single-chain variable fragment that binds to the 3 major isoforms of human vascular endothelial growth factor (VEGF), thereby interfering with their interaction with receptors VEGFR-1 and VEGFR-2 and suppressing endothelial cell proliferation, neovascularization and vascular permeability. BEOVU is administered by intravitreal injection, and the recommended dose is 6 mg monthly for the first three doses, followed by one dose of 6 mg every 8-12 weeks. A marketing application for brolucizumab is undergoing review by EMA.

FDA’s approval was based on data from two Phase 3 studies, HAWK (NCT02307682) and HARRIER (NCT02434328), comparing the efficacy and safety of intravitreal injections of brolucizumab versus aflibercept in nAMD. Brolucizumab met the primary efficacy endpoint of non-inferiority to aflibercept (EYLEA®) in mean change in best-corrected visual acuity (BCVA) at week 48 in both trials, with a mean change in BCVA of 6.6 letters for brolucizumab 6 mg versus 6.8 letters for aflibercept in HAWK trial and 6.9 letters versus 7.6 letters, respectively, in the HARRIER study. Additionally, at week 48, brolucizumab was superior to aflibercept in secondary endpoints considered key parameters of the disease, such as central subfield retinal thickness and retinal fluid (intraretinal fluid and/or subretinal fluid). Results at 96 weeks reaffirmed the superiority of brolucizumab 6 mg in reduction of retinal fluid, and patients who received this dose continued to demonstrate reductions in central subfield thickness.

Antibodies to watch and more

by

The Antibody Society’s presentation, “Antibodies to watch and more: Early and late-stage clinical development trends” was given on June 26, 2019, as part of KNect365’s Digital Week.

In this presentation, Dr. Janice Reichert, Executive Director of the Society, provided an update to the Antibodies to Watch in 2019 paper, which was published in mAbs in February. She gave a brief summary of antibody therapeutics approved January to June this year in either the US or EU, and antibodies in regulatory review and those that might enter regulatory review soon. Dr. Reichert also discussed trends for nearly 160 antibodies that entered clinical study from January 2018 to mid-June 2019, including use of different antibody formats and mechanisms of action, and she provided specifics regarding the popular and less trendy targets.
