A Study of Peginterferon Alfa-2a in Participants With Chronic Hepatitis B Virus (HBV) in an Expanded Access Program

13. december 2016 opdateret af: Hoffmann-La Roche

Expanded Access Program of PEGASYS® (Peg Interferon Alpha-2a 40 KD) in Patients With HBeAg-Positive And HBeAg-Negative Chronic Hepatitis B

This is an expanded access, multicenter, national, open-label, and non-randomized study to analyze the safety of peginterferon alfa-2a in participants with hepatitis B e antigen (HBeAg) positive and HBeAg negative chronic HBV infection. All participants will receive 48 weeks treatment of peginterferon alfa-2a monotherapy, followed by a 24 week treatment-free follow-up period.

Beskrivelse

Inclusion Criteria:

  • Non-cirrhotic participants
  • Hepatitis B surface antigen (HBsAg) positive for at least 6 months
  • Hepatitis B surface antibody (anti-HBs) negative
  • Elevated serum alanine aminotransferase (ALT) greater than (>) upper limit of normal (ULN) but less than or equal to (</=) 10 times of ULN

  • Participants with chronic hepatitis B (CHB) who are treatment-naive
  • No previous antiviral treatment with interferon (IFN: standard or pegylated) or with a nucleoside analogue
  • For women of childbearing potential: negative urine or serum pregnancy test documented within the 24-hour period prior to the first dose of test drug. Willingness to use reliable contraception during the study and for 3 months after treatment completion

Exclusion Criteria:

  • Alpha-fetoprotein levels of >100 nanograms (ng)/mL
  • Severe psychiatric disease
  • History of a severe seizure disorder or current anticonvulsant use
  • History of immunologically mediated disease, chronic pulmonary disease associated with functional limitation, severe cardiac disease, major organ transplantation or other evidence of severe illness, malignancy, or any other conditions which would make the participant, in the opinion of the investigator, unsuitable for the study

Foranstaltningsbeskrivelse
Tidsramme
Number of HBeAg Positive Participants With Hepatitis B Virus-deoxy Ribonucleic Acid (HBV-DNA) Less Than (<) 100,000 Copies Per Milliliter (Copies/mL)
Tidsramme: End of 24-weeks follow-up (Week 72)
HBV-DNA was assessed in plasma samples using quantitative Roche polymerase chain reaction (PCR) or Taqman tests.
End of 24-weeks follow-up (Week 72)
Number of Participants With HBV-DNA <20,000 Copies/mL
Tidsramme: End of 24-weeks follow-up (Week 72)
HBV-DNA was assessed in plasma samples using quantitative Roche PCR or Taqman tests.
End of 24-weeks follow-up (Week 72)

Sekundære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Number of Participants With HBV-DNA <400 Copies/mL
Tidsramme: Week 48 (end of treatment) and Week 72 (end of follow-up)
HBV-DNA was assessed in plasma samples using quantitative Roche PCR or Taqman tests.
Week 48 (end of treatment) and Week 72 (end of follow-up)
Number of Participants With Hepatitis B Surface Antigen (HBsAg) Seroconversion
Tidsramme: Week 48 (end of treatment) and Week 72 (end of follow-up)
HBsAg seroconversion was defined as the absence of HBsAg (a negative result for HBsAg) and the presence of anti-HBs (a positive result for anti-HBs). Both HBeAg positive and negative participants were HBsAg positive at baseline and absence of HBsAg (seroconversion) was analyzed.
Week 48 (end of treatment) and Week 72 (end of follow-up)
Number of Participants With Normalization of Alanine Aminotransferase (ALT) Level
Tidsramme: Week 48 (end of treatment) and Week 72 (end of follow-up)
ALT is an enzyme found mainly in liver and is measured to check if the liver is damaged or diseased. In case of liver damage or disease, the liver releases ALT into the blood stream and the ALT level increases. Normal ALT level = less than upper limit of normal (40 units per liter).
Week 48 (end of treatment) and Week 72 (end of follow-up)
Number of Participants With HBeAg Seroconversion
Tidsramme: Week 48 (end of treatment) and Week 72 (end of follow-up)
HBeAg seroconversion for HBeAg positive participants was defined as the loss of HBeAg (a negative result for HBeAg) and the presence of anti-HBe (a positive result for anti-HBe).
Week 48 (end of treatment) and Week 72 (end of follow-up)
