An Open-label, Non-randomized, Single-arm Study to Investigate the Mechanism(s) by Which Nevirapine Increases Plasma HDL in HIV+ Subjects
An Open-label, Non-randomized, Single-arm Study, to Investigate the Mechanism(s) by Which Nevirapine Increases Plasma High Density Lipoproteins Concentration in HIV+ Subjects Treated With VIRAMUNE® Tablets
In order to obtain further insight as to how NVP affects HDL metabolism, the in vivo kinetics of the HDL apolipoprotein, Apo A-1, before and 6 weeks after initiation of NVP containing treatment were evaluated. In addition, the activity of the key enzymes related to HDL metabolism were assessed.
[ Designated as safety issue: No ]
- In order to determine the relevance of the HDL increase in decreasing cardiovascular risk in HIV-positive subjects we evaluated endothelial function (FMD) as a surrogate marker for cardiovascular disease in patients.

Description
Inclusion Criteria:
Patients will be included when they meet the following criteria:
- 18 years of age or older.
- Ability and willingness to provide signed and dated written informed consent prior to admission to the study in accordance with GCP and local legislation.

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
IPD Plan Description
Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
