| E.1.2 | Version | 9.1 |
| E.1.2 | Level | LLT |
| E.1.2 | Classification code | 10020192 |
| E.1.2 | Term | HIV-1 |

| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
• To evaluate the pharmacokinetics of saquinavir that, when boosted with ritonavir, provides a systemic exposure in HIV-1 infected infants and children 4 months to < 6 years similar to that which has been shown to be safe and effective in older children and adults. • To determine the safety and tolerability of saquinavir when boosted with ritonavir in HIV-1 infected infants and children 4 months to < 6 years of age. |
|
| E.2.2 | Secondary objectives of the trial |
• To characterize the pharmacokinetics of ritonavir when given as a booster in combination with saquinavir in HIV-1 infected infants and children 4 months to < 6 years. • To evaluate the antiviral activity of saquinavir when boosted with ritonavir against HIV-1 infection in infants and children 4 months to < 6 years. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
1. Confirmed HIV-1 infection by HIV-DNA polymerase chain reaction (PCR) if patient < 18 months old or by HIV enzyme-linked immunosorbent assay (ELISA) confirmed by Western Blot analysis (GPA, Gelatin Agglutination Assay, RNA PCR or suitable assay) if patient > 18 months old. 2. Patient is 4 months to < 6 years of age at the day of the first dosing. 3. Patient for whom saquinavir/ritonavir together with ≥ 2 background ARVs (including NRTIs and which may include a ritonavir boosted PI (PI/r)) is considered appropriate, at the discretion of the Investigator. Most commonly, this would include 2 nucleosides in combination with saquinavir/ritonavir (e.g. SQV/r with zidovudine and didanosine or lamivudine and abacavir sulfate). For patients with extensive prior nucleoside use, double boosted PIs (e.g. saquinavir in combination with lopinavir/ritonavir) in addition to nucleosides may be used. 4. Patient will initiate saquinavir/ritonavir with ≥ 2 background ARVs, at the discretion of the Investigator. 5. For patients who cannot swallow Saquinavir Hard Gel capsules, parent/caregiver is able and willing to open Saquinavir Hard Gel capsule(s), mix the contents in a vehicle and administer the medication with ritonavir as directed in the protocol. 6. Parent/legal guardian is able and willing to provide written Informed Consent prior to screening evaluations. |
|
| E.4 | Principal exclusion criteria |
1. Patient whose weight is less than 4 kg / 8.8 pounds (screening visit). 2. History of sensitivity/idiosyncrasy to saquinavir mesylate, ritonavir, or chemically related compounds or excipients which may be employed in the trial. 3. Relevant history or current condition that might interfere with drug absorption, distribution, metabolism or excretion. 4. Any current clinical or laboratory parameter of PACTG Grade 4. 5. Use of any concomitant medications that may interfere with the pharmacokinetics of saquinavir or ritonavir, including but not limited to the drugs listed below, within 28 days prior to the first dose of study drug: • Clarithromycin • Indinavir • Ketaconazole • Nelfinavir • Rifabutin • Rifampicin • Atazanavir • Fosamprenavir • Phenobarbital • Phenytoine • Carbamazepine • Glucocortocoids 6. Any active opportunistic infection and/or clinically significant finding within 28 days before study entry (screening visit). 7. Patients with malabsorption, (severe chronic diarrhea or vomiting more than two episodes of moderate or severe intensity, not attributed to medication therapy and lasting more than four days) within 28 days of the study. |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
• The primary parameters are AUC0-12h and Ctrough for saquinavir. • Frequency and type of Adverse Effects and laboratory parameters (including change from baseline) at 24 weeks and 48 weeks. |
