HIV Neurocognitive Disorders: A Randomized Clinical Trial of CNS-Targeted HAART
CIT2 is a strategy for targeting HAART (Highly Active Antiretroviral Therapy) to the CNS (Central Nervous System) in patients with HIV associated neurocognitive impairment (HNCI). The primary goal of this study is to evaluate the effectiveness of CNS-targeted (CNS-T) as compared to non-CNS-targeted (non-CNS-T) HAART in treating HNCI globally and in different domains of functioning known to be affected by HIV. It is hypothesized that participants in the CNS-T arm will have greater improvement in neurocognitive functioning than those in the non-CNS-T arm. The secondary goal of the study is to compare participants assigned to CNS-T and non-CNS-T HAART on measures of CNS and systemic HIV suppression (undetectable CSF and plasma VL). It is also hypothesized that although CSF viral suppression will be more frequent in the CNS-T arm, plasma viral suppression will be similar in the two treatment arms.

Primary outcomes
- Neuropsychological Performance Change — Baseline and 16 weeks
The outcome measure is change in performance from baseline to 16 weeks as measured by the global deficit score (GDS). The GDS is calculated by averaging the individual deficit scores from each neurocognitive test. Deficit scores for each test were calculated from age-, education-, gender-, and ethnicity-adjusted raw scores by methods that capture unexpectedly poor performance while ignoring better than expected performance. The GDS ranges in value from 0-5; higher scores indicate poorer cognitive functioning. Subjects with scores greater than or equal to 0.5 are considered cognitively impaired.
