Clinical Trial Summary

Incorporating Hepatitis C Virus (HCV) treatment into opioid maintenance treatment program clinical protocols is an innovative health care delivery model that has been associated with improved HCV treatment uptake in non-pregnant, drug-using populations. This "medical home" approach would combine HCV and opioid maintenance treatment into one treatment regimen and incorporate the expertise of obstetricians, hepatologists, substance abuse treatment providers and pediatricians into one comprehensive clinical care model. The purpose of this study is to evaluate the feasibility/acceptability of a combined, peripartum HCV and opioid maintenance treatment program on adherence to HCV treatment regimens and evaluate the rate of intravenous drug use (IVDU) recidivism, HCV reinfection and health related Quality of Life (QOL) in women with opioid use disorder (OUD) during the first postpartum year.

The protocol involves three separate study phases. All 3 study phases will occur with support from hepatology providers at Magee-Womens Hospital. Phase 1 involves screening, enrollment and a baseline assessment of liver function, HCV infection (genotype, viral load) and blood and urine studies in HCV-infected patients during pregnancy. In Phase 2, subjects will undergo 12 weeks of sofosbuvir/velpatasvir therapy initiated at 2 weeks postpartum. Feasibility/acceptability and adherence to sofosbuvir/velpatasvir will be assessed at 4, 8 and 12 weeks of therapy. In Phase 3, subjects will continue to be followed for 15 months after treatment completion. Treatment effectiveness and sustained virologic response (SVR) will be evaluated at 3 months and rates of IVDU recidivism, HCV reinfection and patient centered outcomes such as health related quality of life (QOL) will be assessed at 6, 9 and 12 months following treatment completion.

6. Documented negative Hepatitis B testing within 3 months prior to enrollment

7. Negative human immunodeficiency virus (HIV) testing within 3 months prior to enrollment

8. Per participant report at screening and enrollment, agrees not to participate in other research studies involving drugs or medical devices for the duration of study participation

9. Plans to deliver at Magee-Womens Hospital of University of Pittsburgh Medical Center (UPMC)

Exclusion Criteria:

1. Participant report of any of the following at Screening or Enrollment:

1. Previous treatment for Hepatitis C virus with a sofosbuvir based regimen

2. Use of any medications contraindicated with concurrent use of sofosbuvir/velpatasvir according to the EPCLUSA package insert

3. Plans to relocate away from the study site area in the next 18 months

4. Current sexual partner is known to be infected with HIV or Hepatitis B virus

5. History of decompensated cirrhosis (history of variceal bleed, ascites or hepatic encephalopathy)

2. Reports participating in any other research study involving drugs or medical devices within 60 days or less prior to enrollment

3. Ongoing illicit drug use evidenced by positive urine drug screen with appropriate confirmatory testing for anything other than marijuana since the first prenatal visit that cannot be explained by a prescribed medication

4. Breastfeeding or pumping and feeding infant breastmilk

5. At screening or enrollment, as determined by the Protocol Chair, any significant uncontrolled active or chronic cardiovascular, renal, liver, hematologic, neurologic, gastrointestinal, psychiatric, endocrine, respiratory, immunologic disorder or infectious disease (other than Hepatitis C)

6. Has any of the following laboratory abnormalities at Screening:

1. Aspartate aminotransferase (AST) or alanine transaminase (ALT) greater than 10 times the upper limited of normal

2. Hemoglobin less than 10 g/dL
