BACKGROUND: CPI-1189 is a compound with antioxidant properties that blocks tumor necrosis factor-alpha (TNFalpha) effects in animal models. It has neuroprotective properties in model systems for HIV-associated neurotoxicity and thus is a candidate for neuroprotective therapy in humans with HIV-associated CNS disease.
OBJECTIVE: To assess the tolerability and safety of CPI-1189 in treating HIV-associated cognitive-motor impairment.
METHODS: Sixty-four subjects with mild to moderate HIV-associated cognitive-motor impairment were randomized to receive either placebo or 50 or 100 mg daily of CPI-1189 in addition to optimal HIV therapy. Subjects were followed prospectively in a double-masked study for 10 weeks. The primary assessment was tolerability and safety of the compound. Secondary objectives examined neuropsychological and functional change associated with this treatment.
RESULTS: The study compound was well tolerated, with 91% of CPI-1189-treated subjects and 76% of placebo-treated subjects completing the trial. Skin rash was seen equally in placebo and active arms, but the only study withdrawals due to skin rash occurred in CPI-1189-treated subjects (n = 2). One subject developed a cataract on drug (100 mg/day). CD4 lymphocyte counts and plasma HIV viral load remained stable in all groups throughout the trial. No significant treatment effects were observed on the change in composite Z-scores for eight neuropsychologic measures (NPZ-8). The Grooved Pegboard Test (nondominant) showed improved performance with CPI-1189 at 100 mg/day (p = 0.01), but no other neuropsychometric or functional measures demonstrated significant improvement.
CONCLUSIONS: CPI-1189 was well tolerated in HIV subjects with cognitive-motor disorder. This study was not powered to conclusively determine efficacy and showed no consistent treatment-associated improvement in cognitive or functional measures.
