SMA-TB: Adjunctive Acetylsalicylic Acid and Ibuprofen for Tuberculosis
Study Details
Study Description
Brief Summary
The purpose of this study is to assess the efficacy and safety of 2 repurposed drugs (acetylsalicylic acid and ibuprofen), for use as adjunct therapy added to, and compared with, the standard of care (SoC) WHO-recommended TB regimen in drug-sensitive (DS) and multi-drug resistant (MDR) TB patients.

Phase 2 |
Detailed Description
If eligible and informed consent obtained, patients will be randomized 1:1:1 into one of the following 3 arms, to receive:
-
Standard of Care (SoC) TB treatment + placebo twice daily during the first 4 weeks of TB treatment followed by placebo once daily for an additional 4 weeks. (control group).
-
SoC TB treatment + acetylsalicylic acid 300mg twice daily during the first 4 weeks of TB treatment followed by acetylsalicylic acid 300mg once daily for an additional 4 weeks.
-
SoC TB treatment + ibuprofen 400mg twice daily during the first 4 weeks of TB treatment followed by ibuprofen 400mg once daily for an additional 4 weeks.

Outcome Measures
Primary Outcome Measures
- Time to ≥ 67% sustained reduction in the TB score [Week 8 of follow-up]
Time to ≥ 67% sustained reduction in the TB score over the course of TB treatment
- Hazard ratio for time to stable culture conversion (SCC) [24 weeks of TB treatment]
Hazard ratio for time to stable culture conversion (SCC), at least 2 consecutive negative cultures for M. tuberculosis at least 4 weeks apart during the first 24 weeks of TB treatment.
Secondary Outcome Measures
- Hazard ratio for stable culture conversion (SCC) at week 8 and week 16 after treatment start. [At week 8 and week 16]
Difference between each intervention arm and control group
- Proportion of patients with improvement or resolution of clinical signs and symptoms at end of treatment (TB score). [At week 24]
Difference between each intervention arm and control group
- Proportion of patients with improvement of lung function impairment as change from baseline at week 8, 24 and end of treatment in the 1-second forced expiratory volume (FEV1) expressed as FEV1. [At baseline, week 8 and week 24]
Difference between each intervention arm and control group
- Changes in the BCN-SA Radiological Score Value. [At baseline, week 8, week 24 (and month 12 if MDR)]
Change in chest-X ray (measured with the BCN-SA score) using the x-ray taken at baseline as the comparator compared with subsequent x-rays over the course of TB therapy. Difference between each intervention arm and control group. The BCN-SA Radiological Score Value assesses the sum of acute and chronic findings in the chest X-ray. Per each finding, a minimum score of 0 and a maximum score of 8 is recorded. The total score value is calculated by adding all the individual findings score values. Higher values of total score represent a worse outcome.
- Number of patients with improvement of Health-related Quality of Life comparing baseline measure with that over the course of therapy. [At week 8, week 24 and for MDR TB patients at the end of treatment]
Difference between each intervention arm and control group
Other Outcome Measures
- Safety 1: SAEs participant proportion. [Up to month 6 in DS TB patients and up to month 20 in MDR TB patients]
Proportion of participants with at least one serious adverse events (SAEs) by arm until the end of TB treatment, between each intervention arm and the control group.
- Safety 2: SAEs in person time. [Up to week 12]
Serious adverse event (SAEs) rate expressed in person time, starting the day of the first dose of NSAID or placebo until one month (30 days) after the last placebo or NSAID taken, including all adverse events recorded in each arm.
- Tolerability 1: permanent discontinuity proportion. [Up to week 8]
The proportion of patients in each arm who either permanently discontinued either placebo, acetylsalicylic acid or ibuprofen.
- Tolerability 2: treatment interruption proportion [Up to week 10]
The proportion of patients in each arm who had TB treatment interruption for longer than seven days/doses, prescribed either by a listed investigator, or a non-study physician up to two weeks after scheduled or unscheduled permanent discontinuation of placebo/NSAID

- Patients with HIV infection (irrespective of ART status) if:
-
CD4 <350 cells/mm3
-
if on ART, unsuppressed (>200 copies/ml) viral load
-
if not on ART, either in the opinion of the attending doctor or according to local ART guidelines, the patient should initiate ART during the 8-week initial placebo or NSAID treatment phase.
-
Alcohol use: potential participant either self-reports or in the investigator's opinion that the patient drinks more than an average of four units/day over a usual week or is a binge drinker (men: 5 or more drinks; women: consume 4 or more drinks, in about 2 hours).
