Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • 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

Exclusion Criteria:

  • 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

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in the Odds of Mycobacterium leprae (M. leprae) Growth in Mouse Footpads Following 8 Weeks of Treatment with Bedaquiline
Time Frame: 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.
Baseline up to Week 8

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants with Adverse Events (AEs)
Time Frame: Up to 124 Weeks
An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.
Up to 124 Weeks
Number of Participants with AEs by Severity
Time Frame: Up to 124 Weeks
Severity of adverse events will be graded by using division of microbiology and infectious diseases (DMID) adult toxicity scale to estimate grade of severity. Severity scale ranges from Grade 1 (Mild) to Grade 4 (Life-threatening). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, and Grade 4= Life-threatening.
Up to 124 Weeks
