Hiv Hepatitis C Pregnancy Glecaprevir/Pibrentasvir

ClinConnect Summary

This clinical trial is studying the safety and how the body processes a medicine called glecaprevir/pibrentasvir (GLE/PIB) when it is started during pregnancy in women who have hepatitis C, with or without HIV. The goal is to learn if this treatment is safe for both the pregnant women and their babies, with follow-up until about 10 weeks after birth.

Women who might join the study are between 16 and 45 years old, currently pregnant between 14 and 32 weeks, and have hepatitis C that is confirmed by recent testing. Women living with HIV can also join if their HIV is well-controlled with certain medications. To participate, women need to be willing to provide consent for themselves and their babies and plan to stay near the study site during pregnancy and after delivery. Women who have had certain liver problems, previous hepatitis C treatment, or a high risk of early labor won’t be eligible. If accepted, participants will receive the study medicine during pregnancy, and doctors will carefully monitor their health and their baby’s health to understand how the medicine works and ensure safety.

Eligibility criteria

  • Inclusion Criteria:
  • Of legal age or circumstance to provide independent informed consent as determined by site standard operating procedures (SOPs) and consistent with institutional review board/ethics committee (IRB/EC) policies and procedures
  • Willing and able to provide written informed consent for their own and their infant's study participation
  • At entry, 16-45 years of age (inclusive)
  • At entry, gestational age of 14-32 weeks, defined as greater than 13 weeks plus six days and less than or equal to 32 completed weeks gestation, as determined by the site investigator based on best obstetric estimate
  • At screening and at study entry, no evidence of multiple gestation, fetal anomalies, or intrauterine fetal growth restriction, as determined by the site investigator based on ultrasound
  • At screening, detectable HCV RNA test result based on testing of a specimen collected within 30 days prior to entry
  • At screening, negative test results for hepatitis B surface antigen based on testing of a specimen collected within 30 days prior to entry
  • At screening (i.e., from specimens collected within 30 days prior to entry), has normal, grade 1, grade 2, or grade 3 results for the following
  • Aspartate aminotransferase (AST) (\<10.0 x ULN)
  • Alanine aminotransferase (ALT) (\<10.0 x ULN)
  • At screening (i.e., from specimens collected within 30 days prior to entry), has normal, grade 1, or grade 2 results for the following
  • Hemoglobin (≥8.5 g/dL)
  • Creatinine (≤1.8 x ULN)
  • At screening (i.e., from specimens collected within 30 days prior to entry), has normal or grade 1 results for the following
  • International normalized ratio (INR) (\<1.5 x ULN)
  • Platelet count (≥100,000 cells/mm3)
  • Total bilirubin (\<1.6 x ULN)
  • HIV status determined based on testing meeting the requirements specified in protocol
  • For pregnant participants living with HIV: has a suppressed HIV viral load (HIV-1 RNA below the limit of quantification of the assay) on an ARV regimen for at least 30 consecutive days prior to entry that does not include efavirenz, etravirine, cobicistat, or any protease inhibitor (e.g., atazanavir, darunavir, lopinavir, ritonavir), as determined by the site investigator based on available medical records
  • At entry, expects to remain in the geographic area of the study site during pregnancy and for 10 weeks postpartum (or for 20 weeks post-entry, depending on gestational age at entry), as determined by the site investigator based on pregnant participant report
  • Exclusion Criteria:
  • Previous treatment for hepatitis C with a DAA regimen
  • * High risk of preterm delivery, defined as either of the following:
  • History of spontaneous preterm delivery at less than 34 weeks, as determined by the site investigator based on pregnant participant report and available medical records, or
  • Shortened cervix less than 20 mm if noted on ultrasound during the current pregnancy, as determined by the site investigator based on available medical records
  • Receipt of any prohibited medication, within 14 days prior to entry, as determined by the site investigator based on pregnant participant report and available medical records
  • * Any of the following liver-related conditions:
  • Clinical diagnosis of acute hepatitis not otherwise attributable to hepatitis C with AST or ALT ≥2.5 x ULN
  • Evidence of decompensated cirrhosis including history of or present variceal hemorrhage, ascites, spontaneous bacterial peritonitis, hepatic encephalopathy, hepatocellular carcinoma, hepatorenal syndrome, or hepatopulmonary syndrome
  • Has any other documented or suspected clinically significant medical condition or any other condition that, in the opinion of the site investigator, would make participation in the study unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving study objectives
