Brinsupri Approved for Non-Cystic Fibrosis Bronchiectasis
FDA has approved an Insmed NDA for Brinsupri (brensocatib) tablets as the first treatment for non-cystic fibrosis bronchiectasis (NCFB) in patients aged 12 and older. “There have been no approved therapies for NCFB,” an FDA release says. “Before today’s action, patients relied on antibiotics and symptom management, such as physiotherapy, supplemental oxygen, and mucolytics, which are medications to loosen mucus.”
NCFB is described by the agency as a progressive inflammatory disease that damages the lungs, causing persistent cough, shortness of breath, and recurrent infections. It can develop after prior lung infections, chronic obstructive pulmonary disease, autoimmune disorders, or immune system deficiencies. Between 230,000 and 430,000 Americans are affected by the condition.
FDA says Brinsupri blocks the enzyme dipeptidyl peptidase, which plays a role in the inflammation that drives NCFB. Its approval was based on two multinational, randomized, placebo-controlled trials involving 1,915 adults and 41 adolescents. In one study, both Brinsupri doses significantly reduced the annualized rate of flare-ups — defined as worsening of at least three major symptoms within 48 hours requiring antibiotics — and prolonged the time to the first flare-up compared with placebo. The second trial confirmed the extended time to first flare-up for both doses.
Brinsupri’s labeling carries warnings for skin reactions and gum and tooth problems, advising patients to seek dermatologic and dental care while on treatment, FDA says. Common side effects include upper respiratory tract infections, headache, rash, dry skin, thickened skin, and high blood pressure. Less common effects include elevated liver enzymes, hair loss, and certain skin cancers, it adds.
