MK-0518 Intensification And HDAC Inhibition In Depletion Of Resting CD4+ T Cell HIV Infection

Stopped early · Phase 2

Conditions studied: HIV Infections

In brief

The purpose of this research study is to see if HIV that persists despite current antiviral therapy can be targeted by new treatments. We will see if adding Raltegravir (MK-0518) and Valproic acid (VPA) to current ART can decrease the amount of latent HIV.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• HIV-1 infection
• Men and women age ≥18 years.
• Ability and willingness of subject or legal guardian/representative to give written informed consent.
• Karnofsky performance status >70.
• Willing to adhere to protocol therapy and judged adherent to antiretroviral therapy, and can comply with time requirements for protocol-specified visits and evaluations.
• On potent antiretroviral therapy, defined as at least 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus at least 1 protease inhibitor (PI) or non-nucleoside reverse transcriptase inhibitor (NNRTI), without changes in the 24 weeks immediately prior to entry. Prior changes in or elimination of medications for easier dosing schedule, intolerance, or toxicity are permitted.
• Have no contraindications to valproic acid (VPA) therapy (pregnancy, bleeding disorders, history of pancreatitis, history of hepatitis).
• Have adequate vascular access for leukopheresis
• Plasma HIV-1 RNA never > 50 copies/ml on two consecutive occasions for ≥ 6 months.
• CD4 cell count > 300 cells/µl.
• Screening serum fasting glucose below 120 mg/dl, creatinine no more than 1.5 times the upper limit of the normal range, serum AST, ALT, and total bilirubin less than 2 times the upper limit of the normal range, and fasting triglycerides < 400mg/dl.
• Female study volunteers who are not of reproductive potential or whose male partner(s) has undergone successful vasectomy with documented azoospermia or has documented azoospermia for any other reason, are eligible without requiring the use of contraception.
• All women of reproductive potential must have a negative urine beta-HCG pregnancy test performed at screening, day 0, week 4, week 8, week 12, and every scheduled study visit thereafter.
• All study volunteers must agree not to participate in a conception process and, if participating in sexual activity that could lead to pregnancy, the female study volunteer/male partner must use two reliable methods of contraception simultaneously while receiving the protocol-specified medications and for 6 weeks after stopping the medications. Subjects must use a reliable barrier method of contraception along with another form of contraception. For women receiving ritonavir, estrogen-based contraceptives are not reliable and an alternative method should be used.

You may not qualify if…

• Receiving zidovudine (AZT). Due to the inhibition of zidovudine metabolism mediated by Valproic acid (VPA) a theoretical increase risk of zidovudine-induced anemia exists.
• Using drugs known to interact with valproate or raltegravir (MK-0518)
• Pregnant or nursing.
• Anemic (Hemoglobin < 10gm/dl)
• Seropositive for hepatitis C RNA or hepatitis B surface antigen within 90 days prior to entry.
• Have signs or symptoms of hepatic decompensation
• Received blood transfusions or hematopoetic growth factors within 90 days.
• Use of any of the following within 90 days prior to entry: systemic cytotoxic chemotherapy, investigational agents, immunomodulators.
• Active drug or alcohol use or dependence.
• Serious illness requiring systemic treatment or hospitalization until subject either completes therapy or has been clinically stable on therapy, in the opinion of the site investigator, for at least 90 days prior to entry.
• Compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric illness or a physical illness, e.g., infectious disease.
• Treatment for an active AIDS-defining opportunistic infection within 90 days prior to screening.
• For this pilot study of no direct benefit to subjects, non-English speaking patients are excluded. In the future, if this study is expanded to include a larger sample size, this exclusion criterion may be removed.
