In recent years, substantial progress in the development of anti-tuberculosis (TB) drugs and treatment strategies has accelerated the transition of TB chemotherapy toward shorter-course, all-oral, and increasingly individualized regimens. Over the past year, short-course rifamycin-containing preventive therapies (1HP, 3HP, and 4R) have consistently demonstrated high adherence and favorable safety across diverse populations. In addition, fluoroquinolone-based regimens for contacts of multidrug-resistant TB have gained strong evidence-based support. In the therapeutic domain, multiple phase Ⅱ and Ⅲ trials have further validated the clinical value of novel mechanisms and optimized combinations. New agents such as Telacebec, Quabodepistat, Sutezolid, and Delpazolid exhibit potent bactericidal activity and lower toxicity, laying the foundation for regimen shortening and combination optimization. The BPaL/BPaLM regimens have achieved high cure rates, rapid culture conversion, and good tolerability in real-world studies across several countries. In addition, 9-month (Bedaquiline-Linezolid-Fluoroquinolone-based) and 6-9-month all-oral regimens with varied combinations have shown comparable efficacy across different resistance patterns and resource settings, providing feasible alternatives in regions where Pretomanid availability is limited. For drug-susceptible pulmonary TB, the 4-month rifapentine-moxifloxacin regimen (2HPZM/2HPM) has been endorsed in recent clinical guidelines. Collectively, these developments indicate that TB chemotherapy is shifting from conventional uniform treatment courses toward precision-stratified and individualized management. Future progress is expected to focus on four key directions: discovery of new mechanisms and innovative regimen combinations; precision pharmacological management guided by pharmacokinetic/pharmacodynamic principles and therapeutic drug monitoring; safety assessment and stratified strategies for special populations; and the generation of robust real-world evidence to support globally harmonized yet locally adapted implementation. This review systematically summarizes advances in TB chemotherapy research from October 2024 to September 2025, with emphasis on preventive therapy, treatment of drug-susceptible and rifampicin-resistant TB, and the translation of emerging evidence into clinical practice to inform China's TB control strategies.
