Raltegravir in the Swiss HIV Cohort Study
Raltegravir Use in the Swiss HIV Cohort Study (SHCS) - Evaluation of Efficacy, Safety, Plasma Levels and Evolution of Resistance

Since June 2007, raltegravir has been available in Switzerland within a named patient program for patients who have virologic failure, triple class experience and resistance, and no other treatment options. This proposal has been designed to evaluate efficacy and safety data among patients who receive raltegravir within the routine clinical practice in Switzerland and who participate in the Swiss HIV Cohort Study. This is a combined retrospective analysis of patients who already received raltegravir and a prospective part of patients who enter the named patient program and will be followed up in a standardized way. In the prospective part, patients will also be able to receive raltegravir in case of intolerance to their current medication with virologic suppression.

The analysis will primarily use descriptive statistics. In addition, we will assess the duration of virologic response and focus on predictors of HIV RNA suppression during a follow-up of at least 6 months. In the prospective part, we will assess trough plasma levels of raltegravir and other antiretrovirals. In patients who will develop virologic failure, genotypic and phenotypic resistance to raltegravir (and other antiretrovirals) will be performed to characterize the evolution of resistance during the raltegravir-containing regimen.

Non-Probability Sample

The Swiss HIV Cohort study is a nationwide observational cohort existing for more than 20 years and is representative of the HIV-infected population in Switzerland (approx. 50% of HIV-infected patients in Switzerland, participate in this study). All patients must sign an informed consent to participate in this study.

The study population enrolled in the current "Raltegravir in the SHCS" study, is a subgroup of patients, that has to go on Raltegravir within the Swiss HIV Cohort study.

HIV Infection
Drug: Raltegravir
Raltegravir standard dosage of 400mg tablets every 12 hours together with an optimized backbone antiretroviral drug regimen
Other Name: Isentress
  • Salvage group
    In this group patients are enrolled that have failed previous antiretroviral drug regimens and qualify for Raltegravir treatment according to the approved indication of this drug in Switzerland.
    Intervention: Drug: Raltegravir
  • Switch group
    In this group, patients are enrolled which have to switch to Raltegravir due to drug toxicity or adverse events caused by other antiretroviral drugs.
    Intervention: Drug: Raltegravir
