Descriptive Information
Brief Title  ICMJE TB Host Directed Therapy
Official Title  ICMJE A Ph2 Randomized Trial to Evaluate the Safety Preliminary Efficacy and Biomarker Response of Host Directed Therapies Added to Rifabutin-modified Standard Therapy in Adults With Drug-Sensitive Smear-Positive Pulmonary TB
Brief Summary To examine the safety and preliminary efficacy of multiple adjunctive host directed TB therapies (TB HDT), to assess their potential to shorten TB treatment and/or prevent permanent lung damage.
Detailed Description


To determine the safety and preliminary efficacy of 4 TB HDT candidates:

  1. Safety (treatment emergent serious adverse events and SUSARs)
  2. Microbiologic effects in sputum (culture conversion, change in MGIT TTP) and blood (WBA)
  3. PET/CT imaging
  4. Serum markers of inflammation
  5. Effects on Mtb-specific and general immune function
  6. Pulmonary effects (spirometry, 6MWT, O2 saturation, and St. George Respiratory Symptom Questionnaire) In each case, TB HDT effects will be determined by comparison to patients treated with standard TB therapy alone with regard to a common set of primary and secondary endpoints.


  1. For auranofin, everolimus, and vitamin D: the proportions of patients experiencing suspected unexpected serious adverse reactions (SUSARs).
  2. For CC-11050: the proportion of patients experiencing treatment emergent serious adverse events (SAEs).
