TMC114-TiDP29-C228 – A safety study to evaluate the antiviral activity of darunavir (DRV) in combination with ritonavir (rtv) in HIV 1 infected children from 3 years to below 6 years of age

Conditions
The purpose of this Phase II trial is to evaluate the pharmacokinetics (blood levels), safety and antiviral activity to support dose recommendations by body weight of darunavir with low-dose ritonavir (DRV/rtv), in combination with other antiretroviral drugs (ARVs), in treatment-experienced HIV 1 infected children aged from 3 years to < 6 years and weighing between 10 kg and < 20 kg .

Exclusion Criteria

Patients with presence of any currently active conditions included in the listing of WHO ( World Health Organisation ) Clinical Stage 4 and patients with presence of a non-HIV encephalopathy; Administration of any ARV (antiretroviral) or non-ARV investigational medication or investigational vaccine within 30 days prior to screening, except for those medications where dose recommendations for children are available (Note:DRV should not be used within 14 days following the use of tipranavir); A minimal 14 day washout period is required in which tipranavir must be either interrupted or substituted to an investigator selected PI regimen until the baseline visit; Co-enrollment in other clinical and/or cohort trials without written permission of the Sponsor; Any active clinically significant disease (e.g., tuberculosis [TB], cardiac dysfunction, pancreatitis, acute viral infections) or findings during screening of medical history or physical examination that, in the investigator’s opinion, would compromise the subject’s safety or outcome of the trial
