What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With HBV Deoxyribonucleic Acid (DNA) => 50 IU/mL by Polymerase Chain Reaction (PCR) at Week 72

    HBV DNA assessments were performed using the Roche COBAS® TaqMan High+Pure system (HPS) assay. HBV DNA => 50 IU/mL = approximately => 300 copies/mL.

    Measured: At 72 weeks

  2. Number of Participants With HBV DNA by PCR >= 50 IU/mL Through Week 72

    HBV DNA assessments were performed using the Roche COBAS® TaqMan High+Pure system (HPS) assay. HBV DNA => 50 IU/mL = approximately => 300 copies/mL.

    Measured: At baseline (day 1), week 12, 24, 36, 48, 60, and 72

Secondary outcomes (14)
  1. Distribution of ALT Levels Through 72 Weeks: Overall

    ALT is an enzyme present in serum and various tissues of the body, associated commonly with the liver. Elevated levels of ALT often suggests existence of medical problems which includes viral hepatitis. Normal range varies from laboratory to laboratory. Values of 5-60 U/L is usually considered normal. ALT abnormality = >1.25 x ULN (upper limit of normal).

    Measured: On Day 1 (baseline) and at week 4, 12, 24, 36, 48, 60, 72

  2. Percentage of Participants With HBV DNA < 50 IU/mL (Approximately 300 Copies/mL) by PCR at the End of Post-dosing Follow-up

    HBV DNA assessments were to be performed using the Roche COBAS® TaqMan AmpliPrep assay. HBV DNA < 50 IU/mL = approximately 300 copies/mL.

    Measured: At 72 weeks + 24 weeks follow-up

  3. Percentage of Participants With HBeAg Loss at Week 72 (for HBeAg-positive Participants)

    HBeAg is a hepatitis B viral protein. HBeAg loss = HBeAg-negative at the specified analysis week.

    Measured: At week 72

  4. Percentage of Participants With HBeAg Seroconversion at Week 72 (for HBeAg-positive Participants)

    HBeAg is a hepatitis B viral protein. HBeAg Seroconversion = HBeAg Loss and Presence of Hepatitis B e Antibody (HBeAb).

    Measured: At week 72

  5. Percentage of Participants With HBsAg Loss at Week 72

    HBsAg = a part of the hepatitis B virus that, when in the blood, is an early marker of infection. HBsAg loss = HBsAg-negative at the specified analysis week.

    Measured: At week 72

  6. Percentage of Participants With HBsAg Seroconversion at Week 72

    HBsAg = a part of the hepatitis B virus that, when in the blood, is an early marker of infection. HBs seroconversion is defined as HBsAg loss with positive HBsAb.

    Measured: At week 72

  7. Percentage of Participants With HBsAg Recurrence At Week 72

    HBsAg = a part of the hepatitis B virus that, when in the blood, is an early marker of infection. HBsAg recurrence is defined as having detectable HBsAg among participants who have already experienced loss of HBsAg on-treatment. HBsAg recurrence = HBsAg-positive at the specified analysis week.

    Measured: At week 72

  8. Total Bilirubin at Week 72

    Bilirubin measures are used to diagnose or monitor liver functioning or diseases that include hepatitis. Viral hepatitis is one of the condition in which bilirubin levels are elevated. Normal range varies from laboratory to laboratory. Bilirubin abnormality : => 1.1 x ULN mg/dL.

    Measured: At week 72

  9. Prothrombin Time (PT) at Week 72

    Prothrombin, a liver protein, plays an important role in the extrinsic pathway of clotting. Increased prothrombin time indicates abnormal liver functioning. Normal prothrombin time varies from laboratory to laboratory. Generally, normal prothrombin time varies between 10 to 13.2 seconds. Abnormal PT: > 1.01 x ULN.

    Measured: At week 72

  10. Number of Participants With Liver Rejection Through Week 72

    Measured: Through week 72

  11. Number of Participants With Re-transplantation Through Week 72

    Measured: Through week 72

  12. Participants With Adverse Events (AE), Serious Adverse Events (SAE), and Discontinuations From Study Drug Due to AEs (On-treatment [OT] and Off-treatment Follow-up [OF])

    AE: any new untoward medical occurrence/worsening of pre-existing medical condition, whether or not related to study drug. SAE: any AE that resulted in death; was life threatening; resulted in persistent/significant disability/incapacity; resulted in/prolonged an existing in-patient hospitalization; was a congenital anomaly/birth defect; or an overdose. Toxicity grading by modified WHO grade system. Grade (GR) 2=moderate; GR3=severe; GR4=very severe. OT=from start of dosing to end of dosing+5 days; OF=from end of dosing+6 days to start of other anti-HBV therapy or end of follow-up.

    Measured: OT:From start of dosing through Week 72 + 5 days; OF:End of OT through 24-weeks follow-up

  13. Number of Participants With Laboratory Abnormalities On-treatment (OT) and Off-Treatment Follow-up(OF): Hematology (All Grades)

    Criteria for hematology abnormalities were: Hemoglobin : <11.0 g/dL; White Blood Cells : <4000/mm^3; Neutrophils : <1500/mm^3; Platelets : < 99,000/mm^3; International Normalized Ratio (INR) : increase >= 0.5 from baseline.

    Measured: OT:From start of dosing through Week 72 + 5 days; OF:End of OT through 24-weeks follow-up

  14. Number of Participants With Laboratory Abnormalities On-treatment (OT) and Off-Treatment (OF) Follow-up: Serum Chemistry (All Grades)

    Normal ranges are local lab data and vary according to the site. Criteria for laboratory abnormalities:ALT:>1.25xULN;AST:>1.25xULN;ALP:>1.25xULN;Total Bilirubin:>1.1xULN;Serum Lipase:>1.10xULN;Creatinine:>1.1xULN;Blood Urea Nitrogen:>1.25xULN;Hyperglycemia:>116mg/dL;Hypoglycemia:<64mg/dL;Hyponatremia:<132meq/L;Hypernatremia:>148meq/L;Hypokalemia:<3.4meq/L;hyperkalemia:>5.6meq/L;Hypochloremia:<93meq/L;Hyperchloremia:>113meq/L;Albumin: Decrease >= 1g/dL from baseline and < 3 g/dL. HYPER=value>ULN(upper limit of normal). HYPO=value<LLN (lower limit of normal).

    Measured: OT:From start of dosing through Week 72 + 5 days; OF:End of OT through 24-weeks follow-up

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing entecavir in people with Hepatitis B, Chronic, run by Bristol-Myers Squibb at 32 sites in 9 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 May 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 32 sites in United States, Italy, South Korea, Spain, Brazil and 4 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 31 May 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With HBV Deoxyribonucleic Acid (DNA) => 50 IU/mL by Polymerase Chain Reaction (PCR) at Week 72 (time frame: At 72 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 May 2012.
