Eligibility criteria:

        Inclusion Criteria:

          -  Patients must meet all of the following inclusion criteria to be eligible for
             participation in this study.

                  informed consent form, which must be obtained prior to initiation of the study.

               2. Documented laboratory diagnosis of HIV-1 infection (positive Enzyme-linked
                  immunosorbent assay (ELISA) HIV-1 antibody test confirmed by western blot, p24
                  assay, HIV-1 RNA, or culture).

               3. Have documented plasma HIV-1 RNA level(s) of < 75 copies/ml by branched
                  deoxyribonucleic acid(bDNA) assay, or < 50 copies/ml by Ultrasensitive Polymerase
                  Chain Reaction(PCR) for at least 6 months prior to screening visit.

               4. Currently receiving a stable antiretroviral regimen consisting of enfuvirtide
                  plus at least 2 other antiretrovirals for at least 6 months.

               5. Negative serum pregnancy test (females of childbearing potential only) and are
                  willing to use an adequate method of contraception throughout the duration of the

             this study.

               1. Any prior therapy with MK-0518 or any other HIV-1 integrase inhibitor.

               2. Any HIV-1 viral load > 75 copies/ml by bDNA assay, or > 50 copies/ml by
                  Ultrasensitive PCR assay in the 6 months prior to screening visit (A single
                  "blip" of HIV-1 viral load >75 copies but <400 copies by bDNA assay, or >50
                  copies but <400 copies by Ultrasensitive PCR assay in the six months prior to
                  screening visit with at least one subsequent HIV-1 viral load below the limit of
                  detection will be accepted.)

               3. Any previous known hypersensitivity to components of the study drug formulation.

               4. Weight < 40 kilograms.

               5. Patient requires or is anticipated to require any of the prohibited medications
                  noted in the protocol.

               6. Acute therapy for serious illness (in the opinion of the investigator) within 14
                  days prior to study entry unless the subject has completed ≥ 7 days of therapy
                  and is considered clinically stable by the investigator.

               7. Any condition which, in the opinion of the investigator, would compromise the
                  subject's ability to participate in the study.

               8. Any active opportunistic infections or Centers for Disease Control and Prevention
                  (CDC) Category C conditions (with the exception of stable cutaneous Kaposi's
                  Sarcoma and wasting syndrome due to HIV infection).

               9. Any malignancy requiring chemotherapy.

              10. Subject has any of the following laboratory results at screening:

                  Hemoglobin < 8.0 gr/dl Absolute neutrophil count < 750 cells/ml Platelet count <
                  40,000 Creatinine > 2.0 or calculated creatinine clearance < 40 ml/min

              11. Female patient who is pregnant or breast-feeding, or expecting to conceive or
                  donate eggs during the study. Male patient who is planning to impregnate or
