US Neurologists Cautiously Optimistic About Potential Approval of Pfizer's Zavegepant for the Acute Treatment of Migraine, According to Spherix Global Insights
Recently released positive phase 3 data for Pfizer's zavegepant likely to fuel already noted perceptions among prescribers that the brand will have a high responder rate.
EXTON, Pa., Feb. 28, 2023 /PRNewswire/ -- On February 16, The Lancet Neurology published the Phase 3 results of Pfizer's zavegepant for the acute treatment of migraine. The CGRP receptor antagonist nasal spray has met its co-primary endpoints that a single 10mg dose proved to be more effective than placebo for both pain freedom and freedom from the most bothersome symptom (MBS) at two-hours post-dose. Zavegepant provided relief from migraine pain in 15 minutes, lasting up to 48 hours, according to the release.
Due to these promising results, zavegepant is expected to receive FDA approval for the acute treatment of migraine in early 2023. Pre-launch assessments of zavegepant, collected from a sample of 100 specialists, indicate that Pfizer's asset will be met with some cautious optimism. Specifically, respondents viewed zavegepant as a moderate advancement over other agents in this space, including Impel's Trudhesa, due to its preferred dosing formulation and anticipated responder rate.
Trudhesa, the most recent acute treatment among migraine market entrants, is similar to zavegepant as both are nasal sprays, providing relief in as fast as 15 minutes with one dose and potentially allowing for up to two pain-free days. Though both products are administered intranasally, a major difference between the agents is that Trudhesa is a DHE (dihydroergotamine) while zavegepant is an anti-CGRP, similar to the more proven products, Pfizer's Nurtec ODT and AbbVie's Ubrelvy. Spherix is nearing completion of launch tracking of Trudhesa for its first 18 months of commercial availability.
Results from the most recent Trudhesa deep dive launch assessment – fielded in December 2022 - reveal that uptake can be slow-to-moderate for a newly branded product entering this space. Nurtec ODT, a recent Pfizer purchase and available for the acute treatment of migraine since February 2020 and AbbVie's Ubrelvy, available since December 2019, show the highest physician-reported branded market share, while share of Trudhesa and Eli Lilly's Reyvow – on the market since October 2019 – account for just a fraction of use in comparison.
Fortunately for Pfizer, zavegepant is expected to be available ahead of several other products currently in the pipeline for the acute treatment of migraine. Phase 3 products include Axsome's AXS-07, an oral anti-CGRP with FDA approval expected late 2023; Amneal's DHE autoinjector, expected to be submitted for approval in Q4 2023; and Satsuma's STS-101, a DHE product that would be the first powder nasal spray as opposed to liquid or injection.
