Brief Summary

Acquired drug-resistance is a major challenge for tuberculosis (TB) care programs. The 2020 WHO guidelines recommends replacing second-line injectables by bedaquiline in rifampicin-resistant TB (RR-TB) treatment regimens. However, recent reports show too high rates of acquired bedaquiline resistance. This may be explained by the delayed onset of action of bedaquiline. The investigators will study whether high-dose amikacin (a second-line injectable), administered during the first week of RR-TB treatment, is safe in 20 patients treated for RR-TB in Rwanda. If safe, further studies will assess whether adding amikacin in the first treatment week protect against acquired bedaquiline resistance. This study is embedded in an ongoing "Master study" of the ShORRT (short oral RR-TB) treatment regimen in Rwanda, a before/after study, with a retrospective cohort (before; the previously recommended second-line injectable-containing RR-TB regimen) and a prospective cohort (after: the newly recommended ShORRT regimen).

Outcome Measures

Primary Outcomes (1)

  • grade 3-4 AE likely or definitively related to amikacin

    Assess whether less than 14% of patients treated with the amikacin-strengthened regimen will experience a grade 3-4 adverse event likely or definitively related to the use of amikacin

    After 2 weeks of treatment

Secondary Outcomes (12)

  • turnaround times

    at the end of treatment week 2 (+/- 3 d)

  • testing coverage

    at the end of treatment week 2 (+/- 3 d)

  • AE likely or definitely related to amikacin

    at the end of treatment week 2 (+/- 3 d)

  • amikacin concentration

    during the first two treatment weeks

  • amikacin concentration

    during the first two treatment weeks

  • +7 more secondary outcomes

Study Arms (1)

Amikacin

OTHER
Drug: Amikacin

Interventions

In addition to the all-oral RR-TB treatment, add two intramuscular doses each consisting of 30 mg amikacin/kg, a first dose on day 1 and a second dose on day 4, all in the first week of treatment. The amikacin solution will be admixed with a lidocaine solution in the syringe before administration.
