BioCryst Presents New Real-world Data Showing Rapid, Substantial and Sustained HAE Attack Rate Reductions After Beginning ORLADEYO (berotralstat) Treatment

RESEARCH TRIANGLE PARK, N.C., Feb. 23, 2024 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced new analyses of real-world use of oral, once-daily ORLADEYO (berotralstat) that showed patients who initiated ORLADEYO experienced rapid, substantial and sustained reductions in attack rates through 18 months of treatment regardless of the severity of their disease, their history of prior prophylaxis or their C1-inhibitor (C1-INH) level and function.

The data are being presented in five posters at the 2024 American Academy of Allergy, Asthma & Immunology (AAAAI) annual meeting, which is being held at the Walter E. Washington Convention Center in Washington, D.C., from February 23-26, 2024.

“These additional analyses of real-world use of ORLADEYO show that any person living with HAE has the potential to experience a rapid, substantial and sustained reduction in their monthly attack rate with ORLADEYO. From patients who live with severe disease to well-controlled patients and those who have a history of being treated with other long-term prophylaxis that carry a therapeutic burden, these data demonstrate that once patients begin oral, once-daily ORLADEYO, they can experience attack control over the duration of their treatment,” said Jonathan Bernstein, M.D., professor of medicine, department of internal medicine, division of allergy & immunology at the University of Cincinnati and partner of the Bernstein Allergy Group and Bernstein Clinical Research Center.

Rapid, Substantial and Sustained HAE Attack Rate Reduction After Beginning ORLADEYO Across Multiple Patient Types

Three posters (#012; #008; #281) highlight data collected through BioCryst’s sole-source pharmacy that show real-world effectiveness outcomes for patients aged 12 and above with HAE who initiated ORLADEYO in the United States. These analyses present the overall attack rate progression and attack rate progression stratified by severity (i.e., number of attacks at baseline), prior prophylaxis and C1-INH level and function.

“We are continuing to see strong disease control with ORLADEYO in the real world, including in patients with HAE who report differing baseline disease severities. These findings further demonstrate that ORLADEYO can help maintain disease control in patients with lower baseline attack rates and further reduce attack rates in patients with more active disease. We continue to be encouraged by the consistent, building body of real-world evidence demonstrating the significant benefit that our oral, once-daily prophylactic therapy can provide to people living with HAE,” said Dr. Ryan Arnold, chief medical officer of BioCryst.
