Аннотация
INTRODUCTION: Nontuberculous mycobacteria infect patients who have structural lung disease or those who are immunocompromised. Nontuberculous mycobacterial pulmonary disease (NTM-PD) is increasing in prevalence. Treatment guidelines for Mycobacterium avium complex (MAC) pulmonary disease involve a three-drug regimen with azithromycin, ethambutol, and rifampin, and those of Mycobacterium abscessus complex (MAB) pulmonary disease involve a combination of three or more antimicrobials including macrolides, amikacin, and a β-lactam or imipenem. However, these regimens are poorly tolerated and generally ineffective.
AREAS COVERED: SPR720 is a novel therapeutic agent that has demonstrated activity against a range of NTM species, including MAC and MAB. Encouraging in vitro and pre-clinical data demonstrate that SPR720 is active both alone and in combination with standard-of-care agents, with no evidence of cross-resistance to such agents. It is generally well tolerated with mainly gastrointestinal and headache adverse events of mild or moderate severity.
EXPERT OPINION: Management of NTM-PD is challenging for many reasons including length of therapy, poor efficacy, drug intolerance, recurrence, and resistance development. The current antimicrobial management options for NTM-PD are limited in number and there exists a large unmet need for new treatments. SPR720 has encouraging data that warrant further study in the context of a multidrug regimen.
