Brief summary
Purpose: The purpose of the study is to assess the safety and effectiveness of minocycline, an antibiotic, in the treatment of Human immunodeficiency virus (HIV)-associated cognitive impairment in Uganda. Study Design: Treatment, 24-week Randomized, Placebo-Controlled, Double-Blind Phase with Optional 24-week Open Label Phase for Subjects with a cluster of differentiation 4 (CD4) Count in the 251-350 Range * Arm 1: Minocycline 100 mg orally every 12 hours (50 subjects) * Arm 2: Matching placebo orally every 12 hours (50 subjects) Primary Objective: · To examine whether minocycline treatment will improve cognitive performance after 24 weeks compared to baseline Secondary Objectives: * To examine whether minocycline treatment for 24 weeks is safe and well-tolerated in individuals with HIV-associated cognitive impairment * To examine whether minocycline treatment for 48 weeks is safe and well-tolerated in individuals with HIV-associated cognitive impairment * To examine whether minocycline treatment for 24 weeks improves functional impairment

The outcome is defined as U NP Sum at week 24 - U NP Sum at baseline. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 24-week Change of Karnofsky Performance Score | At baseline and week 24 | The outcome is a new dichotomous variable: no change/worse vs. better at 24 weeks compared to baseline. |
| Time From Treatment Initiation to the Development of a Grade ≥ 2 Toxicity and/or Sign and Symptoms. | Time of initial Grade ≥ 2 toxicity and/or sign and symptom event up to week 24 | The outcome is the time to first Grade ≥ 2 toxicity and/or sign and symptoms from study treatment initiation up to week 24. The grade was determined by clinicians and an Grade ≥ 2 event means moderate, severe, life-threatening, or death event. |
| Time From Treatment Initiation to the Development of a Grade ≥ 2 Toxicity and/or Sign and Symptoms | Time of first Grade ≥ 2 toxicity and/or sign and symptom event up to 48 weeks | The outcome is the time of first Grade ≥ 2 toxicity and/or sign and symptoms from treatment initiation up to 48 weeks. The grade was determined by clinicians and an Grade ≥ 2 event means moderate, severe, life-threatening, or death event. |
| 24-week Change of CD4 Cell Counts | At baseline and week 24 | The outcome is defined as CD4 cell count at week 24 - CD4 cell count at baseline. The unit is cells/mm\^3. |

| 24-week Change of Center for Epidemiologic Studies Depression (CES-D) Score | At baseline and week 24 | The outcome is the total CES-D score at week 24 - the total CES-D score at baseline. The total CES-D score is based on 20 CES-D items, such as I was bothered by things that usually don't bother me and I did not feel like eating, my appetite was poor. Patients were asked to answer each item by 4 scales: (1) Rarely, (2) Sometimes, (3) Occasionally, and (4) Most of the time. After 4 negative items were multiplied by -1, the total CES-D score is a simple sum of all items. The min and Max are 0 and 60, respectively. Higher scores indicate more severe depressive symptoms. |

Recruitment details
The recruitment period was from Mar 2008 to Oct 2009 when the study was stopped early (Data and Safety Monitoring Board (DSMB) decision based on futility) on Nov 2009. The study participants were recruited from the Infectious Disease Institute, Makerere University, Kampala, Uganda.

Outcome results
24-week Change of Uganda Neuropsychological Test Battery Summary Measure (U NP Sum)
The U NP Sum is defined as the average of z scores for 9 neuropsychological test subcomponents in the neuropsychological test battery (i.e. the average of norm-adjusted (z) scores for Grooved Pegboard Dominant Hand, Grooved Pegboard Non-dominant Hand, Color Trails 1, Color Trails 2, Symbol Digit, WHO-UCLA Verbal Learning test Trial 5, WHO-UCLA Verbal Learning test delayed recall, Digit Span forward and Digit Span backward). The outcome is defined as U NP Sum at week 24 - U NP Sum at baseline.
