BioCryst Announces Approval of ORLADEYO™ (berotralstat) in Japan for the Prophylactic Treatment of Hereditary Angioedema
RESEARCH TRIANGLE PARK, N.C., Jan. 22, 2021 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced that the Ministry of Health, Labor and Welfare (MHLW) in Japan has granted marketing and manufacturing approval for oral, once-daily ORLADEYO™ (berotralstat) 150 mg for prophylactic treatment of hereditary angioedema (HAE) in adults and pediatric patients 12 years and older.
ORLADEYO is the first and only prophylactic HAE medication approved in Japan. One capsule of ORLADEYO per day works to prevent HAE attacks by decreasing the activity of plasma kallikrein.
ORLADEYO will be commercialized in Japan by BioCryst’s partner, Torii Pharmaceutical Co., Ltd. OrphanPacific, Inc. is BioCryst’s representative partner in Japan and holds the marketing authorization.
Torii will launch ORLADEYO in Japan following the successful completion of BioCryst’s pricing negotiations with the Japanese National Health Insurance System (NHI).
“Until now, HAE patients in Japan had no therapies approved to prevent attacks, so the approval of ORLADEYO marks a significant advance in HAE treatment,” said Goichi Matsuda, president of Torii. “We are pleased to have the opportunity to bring the first oral treatment option to Japanese HAE patients and are actively preparing for the commercialization.”
“Today’s approval of ORLADEYO in Japan represents important progress towards our goal to bring an oral, once-daily treatment to HAE patients around the world,” said Jon Stonehouse, president and chief executive officer of BioCryst. “Thank you to the HAE patients who participated in our APeX-J trial, to the investigators who conducted it, and to Torii and OrphanPacific for their partnership to achieve this milestone to offer a much-needed new treatment option to HAE patients and physicians in Japan.”
BioCryst received Orphan Drug and Sakigake designation for ORLADEYO in Japan and the approval is based on data from the APeX-J and APeX-2 clinical trials. The APeX-J trial in Japan met its primary endpoint (p=0.003) of a reduction in HAE attacks from baseline for ORLADEYO 150 mg compared to placebo, and ORLADEYO was safe and generally well-tolerated in the trial. In APeX-2, ORLADEYO also met its primary endpoint (p<0.001) for ORLADEYO 150 mg compared to placebo and was safe and generally well-tolerated.
In December 2020, the U.S. Food & Drug Administration (FDA) approved ORLADEYO in the U.S. In Europe, the European Medicines Agency (EMA) validated its marketing authorization application (MAA) submission for ORLADEYO and formal review of the MAA under the centralized procedure is underway. The company expects an approval decision in Europe in the second quarter of 2021.
With the approval in Japan, BioCryst is eligible to receive an additional milestone payment of $15 million from Torii upon receipt of a reimbursement price approval from Japan’s National Health Insurance system in excess of the threshold specified in the agreement with Torii. In addition, BioCryst will receive tiered royalties ranging from 20 percent to potentially 40 percent of Japanese net sales.
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
ORLADEYOTM (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.
