Study summary

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.

Study population

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.

Groups and cohorts

  • 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.

    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.

    Drug: Raltegravir

Interventions

  • DrugRaltegravir

    Raltegravir standard dosage of 400mg tablets every 12 hours together with an optimized backbone antiretroviral drug regimen

    Also known as: Isentress

What researchers measure

Primary outcomes

  1. HIV RNA < 50 copies/ml

    Time frame: after 6 and 12 months

Secondary outcomes

  1. durability of HIV RNA suppression

    Time frame: time to virological failure

  2. predictors of HIV RNA suppression (viral load and CD4 at baseline, resistance at baseline for those with detectable HIV RNA, number of active drugs within the salvage regimen

    Time frame: baseline

  3. time course of CD4 lymphocytes

    Time frame: baseline until study end

  4. severe drug-related adverse events

    Time frame: during study period

  5. drug levels of raltegravir and other antiretroviral drugs

    Time frame: during first year of Ral treatment

  6. evolution of resistance in patients with virologic failure while on raltegravir

    Time frame: time to failure
