Clinical Trial Summary

This is a prospective, adaptive, randomized controlled trial comparing the effectiveness of 4 intervention arms on a combined endpoint in adults with confirmed MDR-TB HIV initiating Bedaquiline-containing MDR-TB treatment regimens and on ART (integrase strand transfer inhibitor (INSTI)-based fixed dose combination therapy) in KwaZulu-Natal, South Africa. Interventions arms include: enhanced standard of care; psychosocial support; mHealth using cellular-enabled electronic dose monitoring; combined mHealth psychosocial support. Level of support will be adjusted using a differentiated service delivery (DSD)- informed assessment of treatment support needs.


Clinical Trial Description

This study will follow a 4-arm Bayesian, adaptive trial design. As patients are enrolled, they will be randomized into one of the four arms. The study will be carried out within a common structure to allow for efficient enrollment and analysis. The overall structure is a 4-arm adaptive platform of mHealth and psychosocial adherence support interventions informed by a differentiated service delivery (DSD) approach. Aim 1 is an adaptive study of mHealth and psychosocial adherence support interventions using a Bayesian adaptive design to allow comparison of elements of the intervention separately and in combination. Aim 1 participants will be randomized into one of 4 arms and followed monthly through the 6 months of intervention, then through the end of treatment telephonically, with an additional in-person visit to establish the primary outcome. Primary outcome is a combined clinical/biological outcome at 12 months described below. Hypothesis 1a utilizes all participants while 1b utilizes only those in the mHealth intervention arms (3+4) since granular EDM-measured adherence is required. ;
