A Study to Evaluate the Efficacy, Safety, Tolerability, and Pharmacokinetics of SPR720 as Compared With Placebo for the Treatment of Participants With Mycobacterium Avium Complex (MAC) Pulmonary Disease
United States25 participantsStarted 2022-12-14
Plain-language summary
The purpose of the study is to evaluate
1. The microbiological response and clinical efficacy of SPR720 compared with placebo in participants with nontuberculous mycobacteria pulmonary disease (NTM-PD).
2. The safety and tolerability of SPR720 in participants with NTM- PD
3. The pharmacokinetic (PK) of SPR719, active moiety, following orally (po) administered prodrug SPR720 in participants with NTM-PD.

✓. Has an induced sputum culture at Screening positive for MAC by quantitative culture on solid agar
✓. Is either treatment naïve and has not received any prior treatment for MAC, OR if previously treated for MAC and meets all of the following criteria:
✓. Has a history of successful treatment with sputum culture conversion to negative
✓. Has recent sputum or BAL culture evidence of recurrent or relapsed disease and
✓. Has been off therapy for at least 3 months prior to consent

Exclusion criteria
✕. In the opinion of the Investigator, is not a candidate for a 5-month delay in initiation of standard multidrug therapy to participate in a placebo-controlled clinical trial (e.g., participant has severe symptoms or, extensive disease burden)
✕. Has disseminated or extrapulmonary NTM disease
✕. Has end-stage NTM-PD or treatment-refractory NTM-PD

Slope of the Weekly Sputum Log10 Colony Forming Units Per Millilitre (CFU/mL) Change From Day 1 Through 56 in micro-Intent to Treat (m-ITT) Population
Timeframe: Days 1 through 56 (end of the treatment [EOT])
. Has isolation on lower respiratory (sputum or BAL) cultures of any Mycobacterium species other than those included in MAC within the 6 months prior to consent
✕. Has any other condition or prior therapy, which, in the opinion of the Investigator, would make the participant unsuitable for this study, including compliance with all study assessments and adherence to the protocol schedule of assessment
✕. Prior exposure to SPR720. Participants who are unable to comply with the requirements of the study or who in the opinion of the Investigator should not participate in the study are not eligible
