An Expanded Access Study of Pegasys (Peginterferon Alfa-2a) in Patients With HBeAg-Negative Chronic Hepatitis B

June 10, 2016 updated by: Hoffmann-La Roche

Expanded Access Programme of PEGASYS® (Peg Interferon Alpha-2a 40KD) in Patients With HBe-Ag-negative Chronic Hepatitis B

This is an expanded access programme to make Pegasys (peginterferon alfa-2a) available to patients with HBeAg-negative chronic hepatitis B in Morocco.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving Hepatitis C Virus Deoxyribonucleic Acid <10,000 Copies/Milliliter at Week 72
Time Frame: 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
Time Frame: 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
Time Frame: Up to Week 72
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving Hepatitis B Virus DNA < 400 Copies/mL at Week 72
Time Frame: At Week 72
Participants who had HBV-DNA levels below 400 Copies/mL at the end of follow-up (at Week 72) were reported.
At Week 72
Percentage of Participants Achieving Hepatitis B Surface Antigen Seroconversion at Screening and Week 48
Time Frame: At Screening and Week 48
Seroconversion is defined as the absence of hepatitis B surface antigen (HBsAg) with a negative result for HBsAg and the presence of anti-Haemoglobin (HBs) antibodies (a positive result for anti-HBs) determined at Week 48. Blood samples were analyzed to check whether it is HBsAg-negative and anti-HBs antibodies positive.
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
Time Frame: At Week 72
Percentage of participants showing normal ALT values and HBV DNA levels <10,000 copies/ mL were reported.
At Week 72
