To demonstrate the safety of bone marrow-derived allogeneic human Mesenchymal Stem Cells (hMSCs) in patients with bronchiectasis receiving standard of care therapy, and to explore treatment efficacy
A Phase 1 investigation will be performed to test the safety of two doses of bone-marrow derived hMSCs (20,000,000 and 100,000,000) administered via peripheral intravenous infusion. Group 1: 3 subjects will receive a single administration of allogeneic hMSCs: 20 x106 (20 million) cells delivered via peripheral intravenous infusion Group 2: 3 subjects will receive a single administration of allogeneic hMSCs: 1 x108 (100 million) cells delivered via peripheral intravenous infusion Interim safety analysis will be performed four weeks after the 1st subject is enrolled in each cohort. Continued safety and tolerability with review of adverse events (AEs) will be assessed at each visit. Efficacy parameters (pulmonary function tests, lung diffusion capacity, lung volumes, 6-Minute Walk Test (6MWT), and dyspnea/Quality of Life (QOL) questionnaires) will be assessed every 12 weeks until study completion. Clinical laboratory tests to assess safety will be performed at every visit. High Resolution Computed Tomography (HRCT) scan will be performed at the baseline visit (if not done within three months prior to enrollment) and then at week 24.
