Hereditary Angioedema Patients Report Breakthrough Attacks on Current Injectable/Infused Prophylaxis Medication
—Data presented at European Academy of Allergy and Clinical Immunology (EAACI) Digital Congress—
RESEARCH TRIANGLE PARK, N.C., June 06, 2020 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq:BCRX) today presented findings from two patient surveys conducted to gain insights into patients’ current hereditary angioedema (HAE) treatment expectations, experience and satisfaction. Patient-reported attack history shows patients treated with current injectable or infused prophylactic medications (Takhzyro®, Haegarda®, Cinryze®) continue to experience breakthrough attacks with a mean ranging from 0.9 to 1.8 attacks over the three months prior to survey.
In addition, the majority of patients surveyed did not expect to have zero attacks even when taking prophylaxis therapy.
The data were presented at the European Academy of Allergy and Clinical Immunology (EAACI) Digital Congress.
“While the injectable and infused medications introduced over the past 12 years have provided added prophylactic attack control for HAE patients, most patients in the study continue to experience breakthrough attacks, and medication adherence continues to be a challenge. HAE patients have indicated an interest in new preventative treatment options, with the majority agreeing that they would prefer an oral medication, despite liking their current prophylactic medication,” said Jinky Rosselli, vice president of global business analysis and operations at BioCryst, who conducted the research.
Study Methods and Results
Study participants were U.S. adult patients with a diagnosis of Type I or Type II HAE. Patients participated in surveys in 2018 (n=75) and 2019 (n=100). Two patients participated in both surveys. The patient surveys were conducted anonymously in compliance with the EphMRA code of conduct.
- In the 2019 survey, 85 percent of patients reported taking at least one medicine to prevent HAE attacks, compared to 64 percent in the 2018 survey.
- The majority (89 percent) of patients using prophylaxis in the 2019 survey reported using at least one of the three most commonly prescribed injectable or infused prophylactic therapies.
- Over the three months prior to the survey, these patients reported a mean of 0.9, 1.6 and 1.8 attacks while taking Haegarda®, Cinryze® and Takhzyro®, respectively. Patients taking these injectable or infused therapies reported similar attack rates in the 2018 study.
- In the 2019 survey, 21 percent of patients using prophylaxis reported the expectation to have zero attacks over the next 12 months.
