Design outcomes

Primary

MeasureTime frame
Development of clinical or laboratory-based or both adverse events at any frequency during the first six month of MDR-TB treatment

Secondary

MeasureTime frame
Pharmacokinetics endpoints of second-line anti-TB drugs • Area under the curve (AUC) • Observed Cmax • Volume of distribution • Elimination half life ;Efficacy • Occurrence of ototoxicity (Yes/No) or Hepatoxicity as defined by Common Terminology Criteria for Adverse Event (CTCAE). Hearing loss as defined as 20 dB or more change at any frequency compared to baseline or clinical ototoxicity at the end of 8 months of MDR-TB (conventional) treatment. • Proportion of MDR-TB patients requiring second-line anti-TB regimen modification modifications due to adverse drug events • TB Symptoms profile (Appendix 1) • Time to first negative culture on solid media • Proportion of patients converting to negative sputum culture on solid culture at 4 or 6 or 8 months after treatment initiation • Rate of change of sputum MTB RNA in MBL assay during treatment ;Mycobacteriological identification and characterizations • Identification of MTB complex from direct sputum specimen and susceptibility of first and second-line anti-TB drugs using Taqman Array Card rt-PCR for resistance determining regions in 10 genes • Minimum inhibitory concentration of 12 first and second-line anti-TB drugs using Sensititre MYCOTB plates • Whole Genome Sequence of discordant between TAC and MIC
