Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43865   clinical trials with a EudraCT protocol, of which   7286   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Percentage of Participants With HBeAg Loss and Seroconversion at Week 72
    End point description
    Loss of HBeAg was defined as change of detectable HBeAg from positive to negative. HBeAg seroconversion was defined as change of detectable antibody to HBeAg from negative to positive. Percentages were based on the number of subjects with non-missing HBeAg results or missing HBeAg results imputed as failures at each visit. For the TDF+Peg-IFN 48 Weeks, TDF 48 Weeks + Peg-IFN 16 Weeks, and Peg-IFN 48 Weeks groups, data are presented in the "Not Retreated" column for participants who had not entered the retreatment phase by Week 72, and in the "Retreated" column for participants who did enter the retreatment phase by Week 72. Participants in the Full Analysis Set who were HBeAg reactive or indeterminate at baseline were analyzed. The missing = failure method was used in which participants on study with missing data were considered to have failed to achieve the outcome.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    12 Jan 2011
    1) Modified the TDF 48 Week + Peg-IFN 16 Week group from a response-guided design to a fixed-duration treatment of TDF and Peg-IFN concomitantly for 16 weeks, followed by TDF alone for another 32 weeks; updated the secondary objective and endpoint accordingly. 2) Increased study sample size to 720 (180 in each of the 4 treatment groups). 3) Added clarity to exclude cirrhotic subjects. 4) Removed the allowed 10% variance for eligibility criteria in eligibility time windows. 5) Added the EudraCT number 2010-024586-45 and clinicaltrials.gov identifier NCT01277601 to the protocol.
    15 Apr 2011
    1) A secondary objective to evaluate virological response (HBV DNA < 400 copies/mL [< 69 IU/mL]) was added. 2) Subjects on statins were allowed in the study if they had no evidence of hepatic toxicity on statins. 3) ALT levels in the inclusion criteria were changed from > 2 × ULN ≤ 10 × ULN to numeric cut-off levels of > 60 U/L and ≤ 400 U/L for men and > 40 U/L and ≤ 300 U/L for women. 4) The study entry requirement of CLcr was changed from ≥ 70 mL/min to ≥ 80 mL/min to exclude subjects who may have beginning renal impairment. 5) Fibroscan (< 8kPa) may have been used to verify absence of bridging fibrosis or cirrhosis in order to meet entry criteria, but was limited to countries where Fibroscan was approved for clinical use. For all other subjects and subjects with a Fibroscan ≥ 8kPa who wished to enroll in the study, a screening liver biopsy or documentation of prior results within 12 months of the first study visit was required. 6) α-fetoprotein (AFP) was performed at screening to rule out hepatocellular carcinoma and follow-up AFP was to be repeated at Weeks 24, 48, 72, 96, and 120. 7) Subjects who discontinued study drug(s) prior to the protocol-specified duration should have been followed up to 120 weeks or minimally 72 weeks. Follow-up for subjects who discontinued study drug(s) early was previously required every 4 weeks for 24 weeks, but was extended to minimally Week 72. The visit schedule/study procedures after early discontinuation of study drug(s) were changed to mirror those of the immediate off-treatment follow-up period and beyond. 8) The amendment allowed the predose sample for the liver biopsy substudy to be taken any time after subjects consented, including at screening or between the screening and baseline visits. 9) Flowchart for management of clinical and laboratory AEs was revised to correspond to the toxicity management guidelines described in the protocol. 10) Grading scale for AE severity and laboratory abnormalities was updated.
    02 Aug 2011
    1) Use of lean body weight for calculating CLcr was changed to actual body weight. 2) Retreatment criteria #1 of increased direct bilirubin by > 1.5 mg/dL was changed to increased total bilirubin by > 1.5 mg/dL. 3) Added guidance for investigators on subjects with loss of HBsAg during study drug treatment. 4) Noted that HBV viral sequence analyses, resistance surveillance, and potential resistance testing will only be evaluated for selected subjects as clinically warranted. 5) Blood storage samples for subjects with hepatic flares and from subjects at early discontinuation visits were to be collected for exploratory analyses. 6) Representative hepatotoxic agents were added to the list of excluded medicines in exclusion criterion #13. 7) The numeric value for ALT 10 × ULN was defined as 400 U/L (males) or 300 U/L (females). 8) Frequency of prothrombin time/INR testing was modified to align with flare management guidelines. 9) The statistical considerations section was revised to include additional objectives, end points of interest, analysis conventions, analysis sets, and safety evaluation.
    20 Feb 2012
    1) HBV DNA reporting units revised from copies/mL to IU/mL. 2) Documentation of CHB infection required history of either positive serum HBsAg or HBV DNA for at least 6 months prior to baseline. 3) Inclusion HBV DNA viral load for HBeAg-negative and HBeAg-positive subjects was revised to ≥ 20,000 IU/mL. 4) ALT levels in the inclusion criteria were changed from > 60 and ≤ 400 U/L for men and > 40 and ≤ 300 U/L for women to > 54 and ≤ 400 U/L for men and > 36 and ≤ 300 U/L for women. 5) Study entry requirement of creatinine clearance (CLcr) was changed from ≥ 80 to ≥ 70 mL/min (Amendment 4 only). 6) Clarified the statistical power calculation and reasoning regarding the sample size. 7) Added thyroid-stimulating hormone (TSH) monitoring at Weeks 12, 24, 32, and 48.
    29 Jun 2012
    1) Inclusion HBV DNA viral load for HBeAg-negative subjects was revised to ≥ 2000 IU/mL from ≥ 20,000 IU/mL. 2) Inclusion of anti-HBV treatment-naive subjects and subjects who had taken oral anti-HBV nucleoside therapy with the last dose ≥ 24 weeks prior to screening. 3) Exclusion criteria decompensated liver disease redefined to include subjects with isolated increase in bilirubin who were otherwise excluded as having abnormally elevated values, but otherwise normal clinical parameters of liver function. 4) Randomization strata were redefined to ensure representation of subjects across either HBeAg status and in the 4 dominant genotypes A, B, C, and D. 5) Allow for 1 rescreening of any subject who had previously screen failed twice under a previous protocol amendment. 6) Redefined ULN values for TDF retreatment and flare management after 48 weeks of treatment and management of exacerbation of hepatitis in subjects who had discontinued study drug. 7) Clarified the planned analysis of the secondary endpoint.
    17 May 2013
    1) Local INR testing could be performed, in the opinion of the investigator, if there were safety concerns. 2) The investigator, in conference with the medical monitor, could have provided immediate intervention based on clinical assessment or local laboratory results in the interest of subject safety. 3) Corrected ALT range (typo). 4) Biweekly follow-up visits were updated for consistency with retreatment criteria. 5) Clarified when to restart retreatment or when to return for routine follow-up after Week 48. 6) Clarified the acceptable time frame for scheduling and performing the Week 96 liver biopsy for subjects enrolled in the liver biopsy substudy. 7) Addressed a safety concern where subjects with ALT > 400 U/L (males) or > 300 U/L (females) would not qualify for TDF retreatment based on the retreatment criteria because of their baseline ALT values. 8) Allowed for TDF retreatment with any detectable HBV DNA for subjects with persistently elevated ALT who had been off-treatment for ≥ 12 weeks. 9) Eliminated the requirement for confirmatory or reflex testing prior to retreatment. 10) Clarified the management of hepatic flare by defining the abnormal laboratory values and acceptable ranges. 11) Clarified that HLA typing and biomarker analysis would not be performed in India. 12) Provided guidance on subject discontinuation related to noncompliance of Peg-IFN treatment. 13) Incorporated the use of hepatitis E virus IgM for laboratory testing related to acute hepatitis exacerbation in India. 14) Addressed the management of subjects who experienced loss of HBsAg while on TDF retreatment. 15) Provided guidance on the frequency of laboratory monitoring and changes in Peg-IFN dose related to the occurrence of neutropenia and thrombocytopenia. 16) Updated safety definitions and provided clarification and guidance on the reporting of safety events. 17) Provided clarification on the frequency of retinal examinations in the study.
