A Trial of Stratified Patient-Centered Treatment Regimens for Active TB (SPECTRA-TB)

A Phase 2C Trial of Stratified Patient-Centered Treatment Regimens for Active TB

The A5414 study will evaluate whether treatment for drug-susceptible pulmonary tuberculosis (TB) can be tailored according to a participant's risk of an unfavorable outcome. Participants will be assigned to lower-risk or higher-risk groups using baseline characteristics and then randomized within each group to receive either standard TB treatment or an investigational rifapentine- and moxifloxacin-containing regimen. The study will evaluate whether shorter treatment durations may be used in lower-risk participants and whether the investigational regimen may improve outcomes in higher-risk participants. Safety and tolerability will also be evaluated.

详细说明

SPECTRA-TB is a Phase 2C, randomized, open-label trial of stratified medicine principles in TB treatment to identify the optimal duration of the HP1500ZM regimen for participants in the lower-risk stratum and to demonstrate improved TB-related favorable outcomes of this regimen in the higher-risk stratum. The study risk stratification includes a higher-risk group (1 control arm and 1 experimental arm) and a lower-risk group (1 control and 5 experimental arms).

Eligible participants will be stratified as either lower- or higher-risk based on the risk stratification algorithm which is based on the following results obtained during the screening period: Xpert MTB/RIF Ultra CT value, extent of disease on chest X-ray, age, BMI, sex at birth, diabetes status, and HIV status using the SPECTRA-TB risk algorithm prior to randomization. Those classified into the lower-risk group (consisting of the low and moderate risk randomization strata to facilitate balancing of risk within each lower-risk treatment arm) will be randomized to SOC or one of five durations of the experimental regimens while those classified into the higher-risk group will be randomized to receive either SOC or a single fixed duration of the experimental regimen. The lower and higher-risk groups will have the following arms:

  • Lower-risk: 10, 12, 14, 16, 18, and 26 weeks (5 experimental arms [weeks 10-18] and one 26-week SOC arm with 100 participants in each arm).
  • Higher-risk: Two arms with 26 weeks duration (one SOC arm with 100 participants and one experimental arm with 200 participants).

All participants will be followed for 72 weeks from randomization for outcomes of efficacy, safety, and tolerability. Participants will be monitored closely for Possible Poor Treatment Response (PPTR), TB treatment failure or TB recurrence, safety, tolerability, and loss to follow-up.
