Additional real-world studies show sustained HAE attack rate reduction after initiating ORLADEYO, regardless of C1-INH status, and patient preference for an oral LTP therapy
RESEARCH TRIANGLE PARK, N.C., Oct. 24, 2024 (GLOBE NEWSWIRE) — BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced new real-world comparative research on the use of oral, once-daily ORLADEYO® (berotralstat) that found high rates of adherence and persistence for ORLADEYO, similar to the rates observed with two other long-term prophylactic (LTP) therapies for hereditary angioedema (HAE).
The company also announced new real-world evidence showing statistically significant and sustained HAE attack rate reductions after initiating ORLADEYO in patients with HAE, regardless of their C1-inhibitor (C1-INH) deficiency status, and new findings from an HAE patient survey confirming patient preference for an oral LTP therapy.
“These results build on previous research that highlights how the real-world effectiveness and convenience of our oral, once-daily prophylactic therapy are differentiators for patients. The strong adherence, persistence and preference for ORLADEYO we report here provide further evidence that enables physicians to optimize individualized treatment recommendations for each of their patients. We continue to generate real-world evidence demonstrating that ORLADEYO is a powerful, potentially life-changing treatment for many people with HAE,” said Dr. Donald S. Fong, chief medical officer of BioCryst.
The data are being presented at the Annual Scientific Meeting of the American College of Allergy, Asthma & Immunology (ACAAI), which is taking place in Boston from October 24-28, 2024.
High Adherence and Persistence Rates for ORLADEYO and Other LTP Therapies
Poster #R072 explores adherence and persistence rates among patients with HAE following initiation of ORLADEYO (n=90) compared with lanadelumab (n=189) and subcutaneous plasma-derived C1-inhibitor (SC-pdC1-INH) (n=78).
“Our findings reveal that among HAE patients managed with LTP, high adherence and persistence rates were demonstrated for ORLADEYO. There was a striking consistency between first line therapies with comparable results for lanadelumab and SC-pdC1-INH. ORLADEYO rates were equivalent to – and in some cases better than – these LTP counterparts. The outcomes of our study provide further support for a shared decision-making approach within the physician-patient partnership to inform LTP selection, incorporating effectiveness, safety, treatment burden and patient preference for each individual,” said Sandra Christiansen, MD, professor of medicine and director of translational research at the US HAEA Angioedema Center at the University of California, San Diego.
Methods
Sustained HAE Attack Rate Reduction After Beginning ORLADEYO Regardless of C1-INH Status
Posters #R092 and #R093 evaluate self-reported HAE attacks prior to and following ORLADEYO initiation among patients with and without HAE with C1-inhibitor deficiency (HAE-nl-C1-INH), respectively.
“ORLADEYO was associated with statistically significant and sustained reductions in attack rates through 18 months (540 days) following ORLADEYO initiation, regardless of patients’ C1-INH status. Importantly, in this real-world study, patients with zero attacks at baseline were included, compared to the minimum of two attacks that was required at baseline in APeX-2. These data confirm that many already well-controlled HAE patients enjoy continued or improved attack control once they initiate ORLADEYO,” Dr. Fong added.
Methods
Patients with HAE Prefer Oral LTP
Poster #R081 examines the LTP treatment preferences of patients with HAE, as collected through an online survey.
“We are encouraged to see both effectiveness and convenience are drivers of treatment preference with patients preferring oral therapy over injectable therapy when efficacy is assumed equal. Given the benefits of treatment with ORLADEYO for patients who remain on therapy over the long term, we believe we will continue to see the preference towards oral therapy reflected in the strong commercial performance of our oral, once-daily prophylactic therapy for HAE,” Dr. Fong noted.
Methods
In addition to displaying in the exhibit hall at the noted times, ePosters are accessible online and on demand to registered attendees on ACAAI’s website.
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
INDICATION
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).
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.
