  1. 01HumanRandomized controlled trialEfficacy outcome

    In virally suppressed adults with HIV and abdominal obesity, tesamorelin showed a trend toward improved neurocognitive performance, but the difference from standard of care was not significant.

    Summary
    The tesamorelin group showed a trend toward improved neurocognitive performance after 6 months (mean change, 0.146; 95% CI, -.002 to .294; P = .060) while the SOC group did not (0.103; 95% CI, -.095 to .301; P = .295), but the between-group difference was not significant (P = .673).

    The primary outcome was the change in neurocognitive performance at 6 months, with secondary outcomes including WC, mood, and daily functioning.
    Summary · context
    This 6-month phase 2 randomized open-label clinical trial compared tesamorelin vs standard of care (SOC) for NCI in people with HIV who were virally suppressed and abdominally obese (elevated waist circumference [WC]).
    Summary · context
    Seventy-three participants were randomized 3:2 to tesamorelin or SOC (2 mg subcutaneously daily).
