BOS is a rapidly progressive inflammatory rare disease that irreversibly destroys the airways of the lungs and usually leads to respiratory failure and death within two to four years after diagnosis. Unfortunately, approximately 50 percent of lung transplant patients develop BOS within five years post-transplant, the highest rejection rate of any transplanted organ. Currently, there is no approved treatment indicated for BOS.
The completion of enrollment in our Phase 3 BOSTON-1 and -2 studies represents a significant milestone for Zambon and the patient community we aim to serve. On behalf of the Company, we would like to thank the many participants in our Phase 3 clinical program, as well as our study sites and investigators for their commitment. We look forward to reporting top-line results from the program during 2024.
At Zambon, we are committed to advancing new therapeutic options that have the potential to make lives better for people affected by severe respiratory diseases such as BOS. The completion of enrollment in our pivotal trials brings us one step closer to our goal of bringing a much-needed therapy to the lung transplant recipients worldwide with BOS
Zambon is also advancing one additional clinical study, BOSTON-3 – an extension study that is open to eligible participants who complete the BOSTON-1 and-2 studies.
L-CsA-i has received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) and European Medicines Agency for the treatment of BOS, reflecting the high unmet need of the disease. The Fast Track designation was also granted by FDA. If approved, L-CsA-i would be the first treatment indicated for BOS.
