This is a Phase 1/2 multicenter, open-label, single dose trial of 4D-710 investigational gene therapy in adults with cystic fibrosis.
An Open-label, Phase 1/2 Trial of Gene Therapy 4D-710 in Adults With Cystic Fibrosis
This Phase 1/2 trial will evaluate the safety, tolerability, and preliminary efficacy of 4D-710, an investigational gene therapy, in adults with cystic fibrosis (CF) advanced lung disease who are ineligible or unable to tolerate CFTR modulator therapy. A sub-study will evaluate 4D-710 in a cohort of adults with CF advanced lung disease and/or frequent pulmonary exacerbation (PE) while on currently available CFTR modulator therapy.
