A Trial to Evaluate the Male Reproductive Safety of Pretomanid in Adult Male Participants With Drug Resistant Pulmonary Tuberculosis

Korábbi kezelés

• Participants with newly diagnosed tuberculosis and HIV that require initiation of appropriate HIV therapy before participants has received at least 2 weeks of an antituberculosis regimen.
• Received pretomanid and/or delamanid to treat TB

Más betegség

• History of male infertility or vasectomy
• Historical or active disease process of the male reproductive tract that would compromise sperm production. e.g. tuberculous epididymitis.
• History of any illness that, in the opinion of the Investigator, might confound the results of the study or poses an additional risk to the participant by their participation in the study.
• Known chronic hepatitis B or C
• For HIV infected participants:
  • The following antiretroviral therapy (ART) should not be used:
• Stavudine 2. Zidovudine 3. Didanosine 4. Triple NRTI regimen is not considered optimal for HIV treatment (poor efficacy)
• Participants with the following toxicities at screening as defined by the enhanced Division of Microbiology and Infectious Disease (DMID) adult toxicity table (Draft November 2007) where applicable:
• Positive hepatitis B surface Ag, or hepatitis C antibody

Laborértékek

• For HIV infected participants any of the following:
  • CD4+ count <100 cells/μL
  • Received intravenous antifungal medication within the last 90 days
• Platelets <75,000/mm3
• Creatinine >1.5 times upper limit of normal (ULN)
• eGFR ≤ 60 mL/min
• Haemoglobin <8.0 g/dL
• Serum potassium less than the lower limit of normal for the laboratory. This may be repeated once
• AST:
  • ≥3.0 x ULN to be excluded
  • results between 1.5 x ULN and 3 x ULN must be discussed with and approved by the Sponsor Medical Monitor
• ALT:
  • ≥3.0 x ULN to be excluded
  • greater than ULN must be discussed with and approved by the Sponsor Medical Monitor
• ALP:
  • ≥3.0 x ULN to be excluded
  • 2.0 - <3.0 x ULN must be discussed with and approved by the Sponsor Medical Monitor
• Total bilirubin:
  • >1.5 x ULN to be excluded
  • Greater than ULN must be discussed with and approved by the Sponsor Medical Monitor
• Direct bilirubin:
  • greater than 1x ULN to be excluded

Egyéb

• Resistant to fluoroquinolones by rapid molecular test
• Unable to produce semen sample
• Evidence at screening of azoospermia
• Known erectile dysfunction that would prevent ejaculation.

• Understands study procedures and voluntarily provides written informed consent prior to the start of any study-specific procedures.
• Male gender 18 years or over
• Body weight (in light clothing and no shoes) ≥ 45kg.
• A positive molecular test for tuberculosis in sputum either at screening or within one month prior to enrolment.
• Disease Characteristics:
  • Participants must have been diagnosed with TB prior to or at screening
  • Participants' TB should be resistant to rifampicin and/or isoniazid, and susceptible to fluoroquinolones by rapid sputum-based tests.
  • Participants who have had previous treatment for DR-TB for more than 3 months at start of screening should be discussed with the medical monitor.
• A chest x-ray, within 26 weeks prior to or at the screening visit, which in the opinion of the Investigator is compatible with pulmonary TB
