Epetraborole in Patients With Mycobacterium Abscessus Lung Disease

This double-blind, randomized, placebo-controlled, parallel-group, multicenter, prospective, investigator-initiated trial will evaluate epetraborole (EBO) monotherapy in the treatment of adults with Mycobacterium abscessus complex (MABc) Lung Disease (LD) of mild to moderate severity. For this study, two EBO oral dose regimens will be studied in patients with MABc-LD, each compared to a placebo group (ie, 4 treatment groups): 500 mg daily and 750 mg daily. Detailed inclusion and exclusion criteria attempt to identify only those patients who have acceptable risks based upon the EBO preclinical findings, phase 1, phase 2, and Phase 3 experience; standard-of-care procedures; and the specified procedures of the study. Following receipt of informed consent, and a Screening period, eligible patients will be randomized to one of the 4 treatment groups to receive active or matched placebo EBO tablets for 84 days. Patients will be assessed for clinical and microbiological evidence of efficacy. At selected investigative sites, patients will undergo sparse PK sampling. Safety and tolerability will be determined by standard clinical and laboratory assessment, with oversight by a qualified and appropriately constituted Data Safety Monitoring Board (DSMB). Data collected during the study will be analyzed per a comprehensive Statistical Analysis Plan (SAP). The study will be registered on clinicaltrials.gov. The total duration of patient participation is approximately 6 months.
