About

In this pilot study, the investigators would examine the safety and efficacy of integrase inhibitor-Raltegravir in the control of HIV/HBV co-infection.

Full description

There are in total more than 72939 HIV infected people reported in Yunnan, the largest number for any province in China. About 800 HIV inpatients are admitted to our hospital every year, amongst them about 10% co-infected with HBV. HIV and HBV co-infection patients must receive two drugs active against both HIV and HBV, for example Tenofovir disoproxil fumarate (TDF)+ lamivudine (3TC) or TDF+FTC. TDF and 3TC are nucleotide analogues that can inhibit both HIV and HBV DNA polymerases (Dore, Cooper et al. 2004). Combination therapy could decrease drug resistance. In China, TDF is a second-line drug of the national free ART program; however FTC is not in the list of free drugs. There is likely higher risk of causing drug resistance in treating HBV or HIV infection with 3TC or TDF monotherapy than combination therapy.

Raltegravir inhibits the catalytic activity of HIV-1 integrase, and does not significantly inhibit human phosphoryl transferases including DNA polymerases α, β, and γ, and may have less adverse effects. In chronic HBV infection, HBV-DNA does integrate into human DNA which results in difficulty eradicating HBV from the patient's body.

In this pilot study, the investigators would examine the safety and efficacy of integrase inhibitor-Raltegravir in the control of HIV/HBV co-infection.

Inclusion criteria

Ability and willingness to provide written informed consent
HIV-1 infection, documented in patient medical record. Acceptable forms of documentation include positive HIV antibody or detectable HIV RNA
HIV-1 antiretroviral therapy naïve
Chronic HBV infection, defined as HBsAg positive >6 months. Both HBeAg positive and negative subjects will be eligible
Detectable HBV DNA ( > 300 copies/ml)
Serum alpha-fetoprotein (AFP) of ≤ 50 ng/ml within 4 weeks of study entry, or if elevated > 50 ng/ml, an imaging study demonstrating no evidence of hepatic tumor within 4 weeks of enrollment

Exclusion criteria

Allergy or sensitivity to study drug
Pregnancy, breastfeeding or unwillingness/inability to adhere to contraceptive methods for the duration of the study (Female study volunteers must not participate in a conception process (e.g., active attempt to become pregnant). If participating in sexual activity that could lead to pregnancy, the female study volunteer must use the following forms of contraception while receiving study-specific medication(s) and for 30 days after stopping the medication. One of the following methods MUST be used appropriately: (1)Condoms* (male or female) with or without a spermicidal agent; (2)Diaphragm or cervical cap with spermicide; (3)IUD; (4)Hormonal-based method.Condoms are recommended because their appropriate use is the only contraception method effective for preventing HIV transmission.
Prisoners or subjects who are incarcerated
Receipt of the following drugs with anti-HBV activity within 90 days prior to study entry or anticipated receipt during the course of the study including: ADV, telbivudine, alpha interferon, and other investigational agents with anti-HBV activity
Active opportunistic infection
Other causes of chronic liver disease identified (autoimmune hepatitis, haemochromatosis, Wilsons disease, alfa-1-antitrypsin deficiency)
Concurrent malignancy requiring cytotoxic chemotherapy
Decompensated or Child's C cirrhosis
Any other condition which in the opinion of the investigator might interfere with compliance or outcome of the study
