In the authors' words

Rationale: Tuberculosis preventive therapy (TPT) is essential for global tuberculosis control, yet estimated coverage remains well below global targets. Current World Health Organization (WHO)-recommended regimens require 1-9 months of treatment and are associated with suboptimal completion rates. Long-acting injectable (LAI) formulations offer the potential to improve TPT uptake and completion, with ideal products providing "one-and-done" options via a single administration. Sorfequiline, a second-generation diarylquinoline with superior potency over bedaquiline and lower QT prolongation risk, is a promising candidate for LAI TPT.
