HIV Infection Hepatitis C | Drug: Metformin Drug: No metformin treatment | Phase 2 |
HCV antiviral therapy has evolved rapidly in recent years and access to these medications has improved. While SVR is associated with improved liver outcomes, the rate of liver fibrosis regression with SVR is variable and predictors of regression are not well established. In addition, achieving SVR in patients with cirrhosis does not necessarily prevent decompensation or eliminate the risk of HCC. A better understanding of the role insulin resistance and impaired glucose metabolism have on these outcomes in HCV patients who achieve SVR are needed.
Identifying and targeting potentially modifiable risk factors such as IR may be of significant importance in preventing progression of and promoting regression of liver fibrosis, reducing mortality and improving outcomes for HCV-HIV co-infected and HCV-mono-infected patients.
This proposed pilot study will be the first to evaluate the role of Metformin on liver fibrosis in HCV-HIV co-infected and HCV mono-infected patients with IR receiving DAA HCV treatment.
If Metformin is effective in reducing liver fibrosis in this patient population, this will represent a well-tolerated, easy to administer, inexpensive therapy that will protect against negative HCV outcomes. This study will also be an opportunity to evaluate the impact of insulin resistance and hyperglycemia have on viral clearance HCV-infected patients treated with interferon-free regimens. In addition, the study will further explore the relationship between HCV, insulin resistance and AFP levels.

- Use of immune suppressing medications
- Active malignancy
- Current or any previous treatment with Metformin, other oral diabetes medications,insulin
- Pre-existing diabetes (type 1, type 2 or gestational diabetes)
- Clinical evidence of decompensated cirrhosis (ascites, esophageal varices, hepatic encephalopathy, hepatocellular carcinoma)
- Presence of renal impairment or when renal function is not known, and also in patients with serum creatinine levels above upper limit of normal range. Renal disease or renal dysfunction (e.g., as suggested by serum creatinine levels >= 136 umol/L (males), >= 124 umol/L (females) or abnormal creatinine clearance (60 mL/min))
- History of congestive heart failure requiring pharmacologic therapy

Active illicit drug use and stable health illness will not be exclusionary assuming it is unlikely to compromise study adherence to protocol and study drug. In HIV-infected participants, HIV antiretroviral use and suppressed HIV viral load will not be required for participation.
HCV antiviral therapy will not be withheld for any participant that is eligible and desires to start treatment. If HCV treatment is anticipated to be started during the 48-week period of assessment, then participants will not be enrolled.
