Share

FDA has approved a Pfizer NDA for Zavzpret (zavegepant), the first calcitonin gene-related peptide receptor antagonist nasal spray for treating adults with acute migraine headache with or without aura. Approval was based on data from a Phase 3 study that showed Zavzpret was statistically superior to placebo on the co-primary endpoints of pain freedom and freedom from most bothersome symptom at two hours post-dose, the company says. Data also demonstrated pain relief as early as 15 minutes in a prespecified secondary endpoint versus placebo, it says.

“As a nasal spray with rapid drug absorption, Zavzpret offers an alternative treatment option for people who need pain relief or cannot take oral medications due to nausea or vomiting,” Pfizer says. “The most common adverse reactions reported in at least 2% of patients treated with Zavzpret and at a frequency greater than placebo were taste disorders (includes dysgeusia and ageusia), nausea, nasal discomfort and vomiting.”
