Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for pregnant women with hepatitis C, with or without HIV. It studies how the drug glecaprevir/pibrentasvir behaves in the body and how safe it is for mother and baby.

Age
16-45 years old
Sex
Women only
Disease stage
Hepatitis C virus infection (acute or chronic) with virus found in the blood. Pregnancy of 14-32 weeks. For women with HIV, HIV virus is kept under control by HIV medicines.
Earlier treatment
Cannot have had any earlier hepatitis C treatment. Women with HIV need to have taken an HIV medicine regimen for at least 30 days that does not include efavirenz, etravirine, cobicistat or any protease inhibitor.
Biomarker or test result
Hepatitis C virus RNA found in a blood test. Negative test for hepatitis B surface antigen. Blood liver, blood count and kidney results within the limits set by the protocol.

Main reasons for not taking part

  • Any earlier treatment for hepatitis C
  • High risk of early birth, such as a past birth before 34 weeks or a short cervix under 20 mm
  • Twin or multiple pregnancy, birth defects in the baby, or poor growth of the baby in the womb
  • Severe liver disease, such as decompensated cirrhosis or liver cancer
  • Use of a medicine the protocol does not allow in the 14 days before entry

This trial only enrols pregnant participants. The registry sentence this rests on: 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

Who can take part

  • 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

Who cannot take part

  • Any previous treatment for hepatitis C, including HCV DAAs or interferon-based treatment
  • 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
  • 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
  • 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
  • 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

About the trial

What the trial wants to find out

This is a Phase I/II, multi-site, open-label, single arm study to describe the pharmacokinetics (PK) and safety of glecaprevir/pibrentasvir (GLE/PIB) initiated during pregnancy in women with hepatitis C virus (HCV) infection (acute or chronic) with or without HIV and to evaluate safety for their infants through 10 weeks postpartum.

The group in the trial

  • GLE/PIBTreatment being tested

    Pregnant participants will take three (3) GLE/PIB fixed-dose combination tablets orally once daily with food for eight weeks

    Treatment: Glecaprevir/pibrentasvir

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
