Spero Therapeutics announced a poster presentation at IDWeek 2024 showcasing in vitro data on SPR719, the active moiety of SPR720, for treating nontuberculous mycobacterium pulmonary disease (NTM-PD). The study, conducted with Microbiologics, revealed:
1. SPR719's low propensity for resistance development in MAC NTM-PD strains, both alone and combined with standard care antibiotics.
2. High potency against macrolide susceptible and resistant MAC strains.
3. Mutation frequencies about 3 orders of magnitude lower than standard of care comparators.
4. No antagonism when combined with clarithromycin or ethambutol.
These findings highlight SPR720's potential for prolonged combination regimens in NTM-PD treatment.

Key findings include:
- SPR719 concentrations in ELF and AM were greater than total plasma concentrations
- No unexpected safety issues were observed
- Results support further investigation of SPR720 as a potential oral treatment for Non-Tuberculous Mycobacterial Pulmonary Disease (NTM-PD)
