RESEARCH TRIANGLE PARK, NC, USA I February 25, 2021 IBioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today 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 European Commission (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.
If approved, ORLADEYO would be the first oral, once-daily therapy in the European Union to treat patients with HAE by preventing recurrent attacks. The CHMP positive opinion is based on data from the pivotal APeX-2 clinical trial and supporting data from the APeX-S trial. In APeX-2, ORLADEYO met its primary endpoint (p<0.001) for ORLADEYO 150 mg compared to placebo. ORLADEYO showed a positive safety profile and was generally well-tolerated over 48 weeks in both APeX-2 and APeX-S.
“Following the recent approvals in the U.S. and Japan, we continue to focus on bringing our oral, once-daily treatment to HAE patients around the world,” said Jon Stonehouse, president and chief executive officer of BioCryst. “The positive CHMP opinion for ORLADEYO is an important step closer to delivering a new option to HAE patients across Europe and our commercial team is in place and ready to launch quickly upon final EC approval.”
In December 2020, the U.S. Food & Drug Administration (FDA) approved ORLADEYO in the U.S. In January 2021, ORLADEYO was approved by the Ministry of Health, Labour and Welfare in Japan. An Early Access to Medicines Scheme (EAMS) for HAE patients has been approved by the Medicines & Healthcare products Regulatory Agency in the United Kingdom.
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
ORLADEYO™ (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 use
The 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.
