RESEARCH TRIANGLE PARK, N.C., March 11, 2021 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced that the French National Agency for Medicines and Health Products Safety (ANSM) has granted an Autorisation Temporaire d'Utilisation de cohorte (cohort ATU), or Temporary Authorization for Use, for the use of berotralstat to prevent attacks of hereditary angioedema (HAE) in appropriate patients aged 12 and older.
This cohort ATU allows patients with HAE in France to receive treatment with berotralstat before the drug is granted marketing authorization by the European Commmission (EC).
According to the the French Code of Public Health, a cohort ATU is dedicated to high unmet medical needs in serious diseases and covers medicinal products of which the efficacy and safety of use are strongly presumed and intended for a group or sub-group of patients treated and monitored in accordance with criteria defined in a protocol for therapeutic use and collection of information.
"HAE is a debilitating and potentially deadly disease so the early access to a new treatment option for patients is exciting news," said Dr. Laurence Bouillet, head of internal medicine, University Hospital Grenoble, Coordinating Reference Centre for HAE in France (CREAK).
"The cohort ATU represents BioCryst's second early access program approved in Europe and provides patients in France with faster access to treatment," said Jon Stonehouse, chief executive officer of BioCryst.
On February 25, 2021, the company announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending the approval of ORLADEYO™ (berotralstat) for routine prevention of recurrent attacks of hereditary angioedema (HAE) in adult and adolescent patients aged 12 years and older.
The EC will review the CHMP recommendation and a final approval decision from the EC on the marketing authorization application (MAA) for ORLADEYO is expected in the second quarter.
About ORLADEYO ™ (berotralstat)
ORLADEYO™ (berotralstat) is the first and only oral therapy designed specifically to prevent attacks of hereditary angioedema (HAE) in adults 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 INFORMATION An 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) and in patients taking chronically administered P-glycoprotein (P-gp) or breast cancer resistance protein (BCRP) inhibitors (eg, cyclosporine).
Berotralstat is a substrate of P-gp and BCRP. 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.
