Eligibility Criteria

Inclusion Criteria

• Male or females 2 to 18 years of age
• A female is eligible to enter and participate in this study if she is of:
• a. non-childbearing potential (i.e., physiologically incapable of becoming pregnant, including any female who is pre-menarchial); or,
• b. child-bearing potential with a negative serum pregnancy test at screen, a negative urine pregnancy test on Day 1 and who agrees to use one of the following methods of contraception (any contraception method must be used consistently and correctly, i.e., in accordance with both the product label and the instructions of a physician). Note: hormonal contraceptives are not considered a sufficient form of contraceptive for this study.
• Complete abstinence from intercourse from 2 weeks prior to administration of study drugs, throughout the study and for 2 weeks after discontinuation of all study medications. Should a female subject of childbearing potential decide to become sexually active during the course of the study, she must be counselled and be willing to use one of the methods listed below:
• Double barrier contraception (male condom/spermicide, male condom/diaphragm, diaphragm/spermicide)
• Any intrauterine device (IUD) with published data showing that the expected failure rate is less than 1% per year (not all IUDs meet this criterion)
• Any other method with published data showing that the lowest expected failure rate for that method is less than 1% per year. All subjects participating in this study should be counselled on the practice of safe/safer sex.
• Parent or legal guardian (and subject whenever possible) has the ability to understand and provide written informed consent for the subject to participate in the trial. Verbal witnessed assent must be obtained from the subject whenever possible.
• Screening plasma HIV-1 RNA > or =400copies/mL.
• Subject's who, in the investigator's opinion, and following resistance testing where appropriate, are able to construct an active NRTI backbone regimen consisting of 2 NRTIs.
• Subjects must meet one of the following criteria:
• ART-naïve subjects are defined as having had < 4 weeks (28 days) therapy with an NRTI, no previous therapy with an NNRTI and < 1 week therapy with an HIV PI.
• ART-experienced subjects are defined as having had greater than 4 weeks (28 days) therapy with any NRTI(s) and any length of therapy with any NNRTI(s) and/or a PI. PI-experienced subjects will be eligible if they have previously been treated with < three PIs, excluding AGENERASE. Prior therapy with a RTV boosted PI regimen will be considered as only 1 prior PI as long as the RTV dose was below that recommended for use of RTV as an antiretroviral agent. This specific criterion is not applicable to subjects in screening and/or enrolling after approval of Amendment No. 4. - For subjects screening and/or enrolling after the approval of Amendment No.4, PI naive subjects are defined as ART experienced subjects having less than one week of therapy with a PI and no prior experience with AGENERASE. Prior treatment with NNRTIs and NRTIs is permitted (however, subjects will NOT be permitted to receive concurrent NNRTI therapy while participating in this study)

Exclusion Criteria

• Prior history of having received amprenavir.
• Use of non-nucleoside reverse transcriptase inhibitor (NNRTI) therapy within 14 days of study Day 1 or anticipated need for concurrent NNRTI therapy during the study period.
• Have had an AIDS defining illness (acute CDC Category C event) within 28 days of screening.
• Pregnant or lactating.
• Non-nucleoside reverse transcriptase inhibitor therapy within 14 days prior to study drug administration or anticipated need for concurrent NNRTI therapy during the study period.
• Subjects who, in the investigator's opinion, are not able to comply with the requirements of the study.
• An acute CDC Category C event (per 1993/1994 classification) and/or serious bacterial infection(s) within 28 days prior to study drug administration.
• Presence of a malabsorption syndrome or other gastrointestinal dysfunction which might interfere with drug absorption or render the subject unable to take oral medication.
• Presence of any serious medical condition (e.g., hemoglobinopathy, chronic anemia,diabetes, cardiac dysfunction and hepatitis) which, in the opinion of the investigator, might compromise the safety of the subject.
• Current grade 2 or higher serum lipase within 28 days prior to study drug administration and/or history of clinically relevant pancreatitis within the previous 6 months. - Grade 3 or 4 transaminase levels (ALT and/or AST) within 28 days prior to study drug administration and/or clinically relevant hepatitis within the previous 6 months.
• Treatment with radiation therapy or cytotoxic chemotherapeutic agents within 28 days of study drug administration or an anticipated need for such treatment within the study period.
• Treatment with immunomodulating agents (e.g., systemic corticosteroids, interleukins, interferons) or any agent with known anti-HIV activity (e.g., hydroxyurea or foscarnet) within 28 days of study drug administration.
• Treatment with any of the following medications within 28 days prior to receiving study medication or the anticipated need during the study:
• Amiodarone, astemizole, bepridil, bupropion, cisapride, clorazepate, clozapine, diazepin, dihydroergotamine, encainide, ergonovine, ergotamine, estazolam, flecainide, flurazepam, lovastatin, meperidine, methylergonovine, midazolam, pimozide, piroxicam, propafenone, propoxyphene, quinidine, rifabutin, simvastatin, terfenadine, triazolam, zolpidem (these drugs have been excluded for safety reasons).
• Carbamazepine, dexamethasone, phenobarbital, phenytoin, primidone, rifampin, St Johns Wort (these drugs have been excluded because they have the potential to decrease plasma protease inhibitor concentrations) - Systemic chemotherapeutic agents
• Treatment with other investigational drugs/therapies (note: treatments available through a Treatment IND or other expanded-access mechanism will be evaluated on a case-by-case basis in consultation with the sponsor) within 28 days prior to study drug administration
• History of drug or other allergy which, in the opinion of the investigator, contraindicates participation in the trial or known hypersensitivity to any study medications (e.g., documented hypersensitivity to a nucleoside analogue).

• Minimum Eligible Age: 2 Years
• Maximum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
