The most commonly reported adverse events were gastrointestinal adverse events, mainly grade 1, especially in the 2 highest BCX7353-dose groups.
The approval was based on data from a randomized, single-blind, multicenter, dose-ranging, crossover study which evaluated the safety and efficacy of Cinryze in 12 pediatric patients (7 to 11 years old).
Results found that those who received a subcutaneous administration of 300mg lanadelumab once every 2 weeks had an 87% reduction in mean frequency of HAE attacks.
The case-control analysis found no significant difference in the angioedema risk for aliskiren monotherapy and fixed-dose combination compared to BBs with adjusted odds ratio of 0.99 (95% CI, 0.45-2.20) and 1.06 (0.40-2.76), respectively.
“The results suggest that levetiracetam has the same or lower risk for angioedema than phenytoin,” wrote the researchers.
Haegarda reduced the number of HAE attacks by a median of 95% vs. placebo
The human plasma-derived, purified, pasteurized, lyophilized concentrate is derived from large pools of human plasma from U.S. donors.
Upper airway angioedema, while rare, is a potentially life-threatening side effect of ACEIs.
