Résumé
Date de début de l'étude : 1 août 1999
Date à laquelle le premier participant a commencé l'étude.PROTOCOL OUTLINE: This is a randomized, dose escalation, double blind, placebo controlled, multicenter study. Patients are randomized to receive either adeno-associated virus-CFTR (AAV-CFTR) vector or placebo. Patients undergo tests on days -10 to -4 to rule out adenovirus and adeno-associated virus infections. Patients then receive AAV-CFTR vector intranasally to the right or left inferior turbinates and placebo to the other side of the nose. The next day, patients receive an endobronchial dose of AAV-CFTR vector to the superior segment of the right lower lobe. Cohorts of 2-4 patients each receive escalating doses of AAV-CFTR vector until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose level immediately preceding the dose at which at least 2 subjects develop dose limiting toxicity. Patients are followed at day 10, then at 1, 2, 3, 6, 9, and 12 months.
