July 09, 2025 07:00 ET | Source: BioCryst Pharmaceuticals, Inc. RESEARCH TRIANGLE PARK, N.C., July 09, 2025 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced that the company will present new findings from patient-focused research highlighting the burden of current treatments for HAE on pediatric patients under the age of 12 and their caregivers and perspectives on the importance of HAE treatments. The findings will be presented in posters at the 2025 US HAEA National Summit in Baltimore, which is taking place July 10-13, 2025. “For more than a decade, we have been honored to join the HAE patient community at the US HAEA National Summit. It is an opportunity for us to hear directly from them on their hopes and dreams for a brighter future so we can keep working with them and for them to try to make these dreams a reality. This is what drove us to bring the first oral, once-daily prophylactic therapy for HAE for adults and adolescents and will continue to drive us to try to do even more for this community in the future,” said Jon Stonehouse, president and chief executive officer of BioCryst. BioCryst will present the following three abstracts in a poster session on Friday, July 11 from 12:30-1:30 p.m. ET: Patient Perspectives on the Importance of HAE Treatments; Poster #25Burden of Treatment for Pediatrics Patients (Aged Less Than 12 Years) With Hereditary Angioedema and Their Caregivers; Poster #4HAE Attack Rates in Pediatric Patients 2 to <12 Years of Age with Prophylactic Berotralstat: Results from Interim Analysis of APeX-P; Poster #13 (encore from AAAAI / WAO 2025) BioCryst President and CEO Jon Stonehouse will also address members of the HAE community in attendance in a corporate presentation during the Summit. About ORLADEYO® (berotralstat)ORLADEYO® (berotralstat) is the first and only oral therapy designed specifically to prevent attacks of hereditary angioedema (HAE) in adult and pediatric patients 12 years and older. One capsule of ORLADEYO per day works to prevent HAE attacks by decreasing the activity of plasma kallikrein. U.S. Indication and Important Safety Information INDICATIONORLADEYO® (berotralstat) is a plasma kallikrein inhibitor indicated for prophylaxis to prevent attacks of hereditary angioedema (HAE) in adults and pediatric patients 12 years and older. Limitations of useThe safety and effectiveness of ORLADEYO for the treatment of acute HAE attacks have not been established. ORLADEYO should not be used for the treatment of acute HAE attacks. Additional doses or dosages of ORLADEYO higher than 150 mg once daily are not recommended due to the potential for QT prolongation. IMPORTANT SAFETY INFORMATIONAn increase in QT prolongation was observed at dosages higher than the recommended 150 mg once-daily dosage and was concentration dependent. The most common adverse reactions (≥10% and higher than placebo) in patients receiving ORLADEYO were abdominal pain, vomiting, diarrhea, back pain, and gastroesophageal reflux disease. A reduced dosage of 110 mg taken orally once daily with food is recommended in patients with moderate or severe hepatic impairment (Child-Pugh B or C). Berotralstat is a substrate of P-glycoprotein (P-gp) and breast cancer resistance protein. P-gp inducers (eg, rifampin, St. John’s wort) may decrease berotralstat plasma concentration, leading to reduced efficacy of ORLADEYO. The use of P-gp inducers is not recommended with ORLADEYO. ORLADEYO at a dose of 150 mg is a moderate inhibitor of CYP2D6 and CYP3A4. For concomitant medications with a narrow therapeutic index that are predominantly metabolized by CYP2D6 or CYP3A4, appropriate monitoring and dose titration is recommended. ORLADEYO at a dose of 300 mg is a P-gp inhibitor. Appropriate monitoring and dose titration is recommended for P-gp substrates (eg, digoxin) when coadministering with ORLADEYO. The safety and effectiveness of ORLADEYO in pediatric patients <12 years of age have not been established. There are insufficient data available to inform drug-related risks with ORLADEYO use in pregnancy. There are no data on the presence of berotralstat in human milk, its effects on the breastfed infant, or its effects on milk production.
