Brief Summary

This is an expanded access programme to make Pegasys (peginterferon alfa-2a) available to patients with HBeAg-negative chronic hepatitis B in Morocco. Patients will receive Pegasys 180 mcg subcutaneously weekly for 48 weeks and efficacy and safety will be recorded during treatment and for 24 weeks of follow-up.

Conditions

Hepatitis B, Chronic

Outcome Measures

Primary Outcomes (3)

• Percentage of Participants Achieving Hepatitis C Virus Deoxyribonucleic Acid <10,000 Copies/Milliliter at Week 72

  Participants who had Hepatitis B Virus Deoxyribonucleic Acid (HBV-DNA) levels below 100,000 copies per milliliter (mL) at the end of follow-up (at Week 72) were reported.

  At Week 72

• Percentage of Participants Achieving Normalization of Alanine Aminotransferase at Week 72

  Percentage of participants with a normal serum alanine aminotransferase (ALT) level at the end of the study was analyzed. Normal ranges for ALT are 7 to 56 International Units/Litre. Participants with ALT less than the upper limit of normal at end of treatment were reported.

  At Week 72

• Number of Participants With Any Adverse Events and Serious Adverse Events

  An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not considered related to the medicinal (investigational) product. A serious adverse event (SAE) is any significant hazard, contraindication, side effect that is fatal or life-threatening, requires hospitalization or prolongation of an existing hospitalization, results in persistent or significant disability/ incapacity, is a congenital anomaly/ birth defect, is medically significant or requires intervention to prevent one or other of the outcomes listed above

  Up to Week 72

Secondary Outcomes (3)

• Percentage of Participants Achieving Hepatitis B Virus DNA < 400 Copies/mL at Week 72

  At Week 72

• Percentage of Participants Achieving Hepatitis B Surface Antigen Seroconversion at Screening and Week 48

  At Screening and Week 48

• Percentage of Participants Achieving Combined Response Hepatitis B Virus DNA < 10,000 Copies/mL and Normal ALT at Week 72

  At Week 72

Study Arms (1)

Peginterferon alpha-2a, 180 mcg/48 weeks

EXPERIMENTAL

Eligible participants with HI3vAg (a type of Hepatitis B surface antigen) negative chronic hepatitis B will be administered peginterferon alpha-2a (PEGASYS), 40kD, 180 micrograms (mcg) subcutaneously once weekly for 48 weeks. The untreated Follow-up will be for 24 weeks.
