Phase 3 clinical trial data published in the Journal of Cystic Fibrosis
CARY, N.C., March 17, 2021 (GLOBE NEWSWIRE) -- Chiesi USA, Inc., the U.S. affiliate of Chiesi Farmaceutici, an international research-focused healthcare Group (Chiesi Group), today announced the launch of FDA-approved Bronchitol® (mannitol) inhalation powder, an add-on maintenance therapy to improve pulmonary function in cystic fibrosis (CF) patients 18 years of age and older. Bronchitol is the first and only dry powder inhaled mucoactive agent* providing a compact, portable option for patients.
Additionally, data from the global Phase 3 study evaluating the efficacy and safety of inhaled dry powder mannitol in adults with CF has been published online in the Journal of Cystic Fibrosis. In the multicenter, double-blind, randomized, parallel-group, controlled study of 423 adults with CF, subjects received either mannitol 400mg or mannitol 50mg (control), twice-daily via dry powder inhaler for 26 weeks. Authors concluded that mannitol 400mg inhaled twice-daily via a dry powder inhaler statistically significantly improved lung function (FEV1) compared with control, with this improvement supported by sensitivity analyses. Most common adverse reactions (≥3%) include cough, hemoptysis, oropharyngeal pain, vomiting, bacteria sputum identified, pyrexia and arthralgia.
“Chiesi USA has a longstanding commitment to advancing treatments and patient care programs among the CF community, and we are thrilled to add Bronchitol to our comprehensive offering,” said Jon Zwinski, General Manager and Chief Executive Officer of Chiesi USA. “We are excited to bring the first dry powder inhaled mucoactive agent* to the U.S. for adults with CF, delivered by a portable device that doesn’t require routine maintenance or cleaning.”
Bronchitol was developed by Pharmaxis Ltd., and Chiesi is now its exclusive distributor in the United States and 11 countries in Europe. Bronchitol is also approved and marketed in Australia, Europe, Russia, and several other countries.
*The precise mechanism of action of BRONCHITOL in improving pulmonary function in CF patients is unknown. Data suggest that BRONCHITOL may impact sputum properties, however, a causal relationship between changes in sputum properties and pulmonary function have not been demonstrated.
BRONCHITOL (mannitol) inhalation powder is a sugar alcohol indicated as add-on maintenance therapy to improve pulmonary function in adult patients 18 years of age and older with cystic fibrosis. Use BRONCHITOL only in adults who have passed the BRONCHITOL Tolerance Test.
Important Safety Information
BRONCHITOL is contraindicated in patients with hypersensitivity to mannitol or to any of the capsule components. BRONCHITOL is contraindicated in patients who fail to pass the BRONCHITOL Tolerance Test (BTT).
BRONCHITOL can cause bronchospasm, which can be severe in susceptible patients. Because of the risk of bronchospasm, prior to prescribing BRONCHITOL, patients must pass the BRONCHITOL Tolerance Test (BTT). The BTT must be administered under the supervision of a healthcare practitioner who can treat severe bronchospasm.
Patients who pass the BRONCHITOL tolerance test (BTT) may experience bronchospasm with add-on maintenance therapy with BRONCHITOL. Patients should premedicate with an inhaled short-acting bronchodilator prior to each administration of BRONCHITOL. If bronchospasm occurs, immediately discontinue BRONCHITOL and treat bronchospasm with an inhaled short-acting bronchodilator. Hemoptysis can occur with BRONCHITOL use. Monitor patients with history of episodes of hemoptysis. If hemoptysis occurs, discontinue use of BRONCHITOL.
Most common adverse reactions (≥3%) include cough, hemoptysis, oropharyngeal pain, vomiting, bacteria sputum identified, pyrexia, and arthralgia.
