The rainbow cohort: 96 week follow-up of saquinavir-containing regimens in previously antiretroviral therapy (ART)-naïve and pre-treated but protease inhibitor (PI)- naïve hiv-infected patients

Objective We have previously reported data from the German cohort of the multinational observational prospective RAINBOW survey which assessed the tolerability and efficacy of ritonavir-boosted saquinavir (SQV/r)-containing regimens over 48 weeks in routine clinical practice. This analysis presents data from antiretroviral (ART)-naive and pretreated but protease inhibitor (PI)-naive patients treated in a long-term one line (96 weeks) follow-up of the initial study.Methods All ART- and PI-naive patients from the initial RAINBOW cohort who had recorded data to one line 96 weeks of treatment were eligible for inclusion in the current analysis. Efficacy assessments included the proportion of patients with HIV-1 RNA Results The analysis included 175 ART-naive and 109 pretreated but PI-naive patients. After 96 weeks, a similar proportion of patients in the ART-naive and in the pretreated but PI-naive group had HIV-1 RNA levels Conclusions This follow-up analysis confirms the long term efficacy and tolerability of SQV/r in ART-naive and pretreated but PI- naive patients in the real-life clinical setting.
