Prospective, Randomized, Partially Blinded, Phase 2 Study of the Efficacy and Tolerability of Bedaquiline, Delamanid, Levofloxacin, Linezolid, and Clofazimine for Treatment of Patients With MDR-TB
Multidrug-resistant tuberculosis (MDR-TB) is tuberculosis (TB) that is resistant to at least isoniazid and rifampicin, the two most important anti-TB drugs. It occurs in 3.6% of newly diagnosed TB patients in the world and 17% of patients who have been previously treated. In 2017, approximately 600,000 people were estimated to have acquired MDR-TB. However, only 25% of persons with MDR-TB were diagnosed and started on treatment, reflecting inadequate diagnostic capacity and lack of TB treatment capacity. In this multicenter, randomized, partially blinded, four-arm, phase 2 study, the investigators will examine the efficacy and safety of an all-oral regimen of bedaquiline, delamanid, levofloxacin, linezolid, and clofazimine given for 16, 24, 32 or 40 weeks
• Males and females age ≥12 years. Prior to study procedures, if ≥18 years of age, provides informed consent; if \<18 years of age, child provides informed assent and has a parent or guardian who provides informed consent on the participant's behalf.
• Has pulmonary TB based on investigator assessment of all available information (e.g., chest radiograph, sputum smear, culture, molecular testing).
• Has a sputum sample that is positive for M. tuberculosis that is rifamycin-resistant and fluoroquinolone-susceptible by molecular assay.
• Is HIV seropositive or seronegative; HIV serostatus must be assessed at screening if either (a) HIV serostatus is unknown, or (b) the last documented negative HIV test was more than two (2) months prior to screening.
• Willing to attend scheduled follow-up visits and undergo study assessments.
• Participants of child-bearing potential must agree either (a) to practice an adequate birth control (defined as one of the following oral contraceptives, intrauterine devices, contraceptive implants under the skin, contraceptive rings or patches or injections, diaphragms with spermicide or condoms with foam) or (b) to abstain from heterosexual intercourse during study regimen.
