Tuberculosis and Human Immunodeficiency Virus (HIV) Immune Reconstitution Syndrome Trial (THIRST) (THIRST)

May 2, 2010 updated by: Duke University

A Pilot Study Of Open-Label Fixed Dose Combination Zidovudine/Lamivudine/Abacavir In HIV-Infected Persons With Tuberculosis In Moshi, Tanzania; Tuberculosis And HIV Immune Reconstitution Syndrome Trial (THIRST)

The purpose of this study is twofold: (1) to assess the feasibility and safety of fixed dose combination zidovudine/lamivudine/abacavir in HIV infected subjects with tuberculosis in a resource-limited setting, and (2) to assess the impact of delayed versus early initiation strategies for fixed dose combination zidovudine/lamivudine/abacavir on the rate of tuberculosis-associated immune reconstitution inflammatory syndromes.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Serious Adverse Events (SAEs)
Time Frame: 104 weeks
Feasibility and safety of fixed dose combination zidovudine/lamivudine/abacavir in HIV-infected subjects with tuberculosis in a resource-limited setting as assessed by the number of serious adverse events. Serious adverse events included any untoward medical occurrence that resulted in death, was considered life-threatening, required inpatient hospitalization or prolongation of existing hospitalization beyond what was required in the study, or resulted in persistent or resulted in significant disability/incapacity.
104 weeks
Tuberculosis-immune Reconstitution Inflammatory Syndrome Events
Time Frame: 104 weeks
Tuberculosis-immune reconstitution inflammatory syndrome was defined by the protocol as: a) new persistent fevers (temperature >101.5 degrees Fahrenheit) developing after the initiation of antiretroviral therapy, and not believed to be associated with antiretroviral therapy and without an identifiable source, b) marked worsening or emergence of intrathoracic lymphadenopathy, pulmonary infiltrates or pleural effusions on radiologic examination, or c) worsening or emergence of lymphadenopathy on serial examinations or worsening of other tuberculous lesions.
104 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Plasma HIV Ribonucleic Acid (RNA) Level < 400 Copies/ml
Time Frame: 104 Weeks
The number of subjects with plasma HIV RNA level <400 copies/ml.
104 Weeks
HIV RNA Level < 50 Copies/ml
