入选标准
- •Participant has: a) multibacillary (MB) leprosy, defined as 6 or more skin lesions or extensive confluent lesions or diffuse skin involvement, and is either borderline lepromatous or polar lepromatous, as determined using Ridley and Jopling classification system; and b) has a bacteriological index of >=4+ from the lesion biopsy obtained at screening, and a bacteriological index of >= 1+ from each of 4 slit skin smear assessments taken at screening
- •Otherwise healthy on the basis of physical examination, medical history, vital signs, and 12-lead electrocardiogram (ECG) performed at screening. If there are abnormalities, they must be consistent with the underlying illness in the study population. This determination must be recorded in the participant's source documents and initialed by the investigator
- •Otherwise healthy on the basis of clinical laboratory tests performed at screening. If the results of the serum chemistry panel, including liver enzymes, other specific tests, blood coagulation, hematology, or urinalysis are outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant or to be appropriate and reasonable for the population under study. This determination must be recorded in the participant's source documents and initialed by the investigator
- •a man must agree not to donate sperm throughout treatment with TMC207 and for 3 months after treatment is stopped
- •Willing and able to adhere to the prohibitions, restrictions, and long-term follow up requirements specified in this protocol
- •If a woman is of childbearing potential, must be practising a highly effective method of birth control (failure rate of <1% per year when used consistently and correctly) before entry, and must also agree to use a barrier contraceptive method (that is, male or female condom, diaphragm or cervical cap) plus spermicide. participant must also agree to continue to use a highly effective method of contraception plus a barrier method throughout treatment with TMC207 and until 6 months after treatment is stopped
排除标准
- •Has experienced or is experiencing a lepra reaction requiring treatment with a prohibited therapy
- •Has a contraindication limiting the implementation of a medically accepted MB leprosy regimen
- •a) Has ever received pharmacotherapy for leprosy; b) has ever been treated with a drug that is a component of the primary World Health Organization (WHO) regimen for the treatment of MB leprosy (example, dapsone, rifampicin, clofazimine). Short-term (<=2 weeks) pharmacotherapy with any antibiotic that could be used as a second line treatment for leprosy (eg, of the macrolide, quinolone, or tetracycline class) is acceptable as long as the last administration occurred >=4 weeks before first dose of study drug (TMC207)
- •Has a concomitant infection that requires an additional systemic antimicrobial agent
- •Has tuberculosis (TB), as determined by medical history and chest x-ray
- •Is a woman who is pregnant, or breast-feeding, or planning to become pregnant while enrolled in this study or within 6 months after the last dose of study drug
研究组 & 干预措施
Bedaquiline
Participants will receive bedaquiline 200 (milligram) mg (2*100 mg tablets) once daily for 2 weeks followed by 100 mg tablet three times a week (tiw) for 6 weeks with at least 48 hours between doses.
干预措施: Bedaquiline 200 mg (Drug)
结局指标
主要结局
Change from Baseline in the Odds of Mycobacterium leprae (M. leprae) Growth in Mouse Footpads Following 8 Weeks of Treatment with Bedaquiline
时间窗: Baseline up to Week 8
Change from baseline in the odds of M. leprae growth in mouse footpads will be evaluated. M. leprae bacilli will be inoculated in footpads of mice, according to the method of Shepard. M. leprae growth will be determined by technologists trained and experienced in mouse footpad procedures, at 1 year after infection (or at mouse death or humane endpoint, if it occurs greater than or equal to \[\>=\] 6 months after footpad inoculation). The number of footpads with positive growth (\>=10\^5 M. leprae) will be counted and used to determine the odds of bacterial growth.
次要结局
- Number of Participants with Adverse Events (AEs)(Up to 124 Weeks)
- Number of Participants with AEs by Severity(Up to 124 Weeks)
