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   44339   clinical trials with a EudraCT protocol, of which   7369   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.

    General information about the trial
    Main objective of the trial
    To evaluate the safety and tolerability of single or multiple doses of ALN-HBV in healthy adult subjects and non-cirrhotic subjects with chronic hepatitis B virus (HBV) infection when administered as monotherapy or concomitantly with the anti-HBV nucleoside, entecavir, or the anti-HBV nucleotide, tenofovir.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    29 Mar 2016
    Removed Part D multiple dosing in subjects who are anti-HBV treatment-naïve, clarified that the maximum possible dose in Part C is 3.0 mg/kg, amended the stopping rules for Part C to state that dosing will be discontinued if >/=1 subject experiences a serious adverse event (SAE) considered to be possibly or definitely related to study drug, and clarified reasons leading to dosing discontinuation.
    26 Jan 2017
    Included specific alanine transaminase (ALT) inclusion criteria and increased liver function test monitoring. Also, each subsequent dose escalation after 0.1 mg/kg ALN-HBV was to be preceded by protocol-specified Safety Review Committee (SRC) review of safety data. The following additional protocol changes were made: • For Parts B and C, a normal and stable serum ALT was added as a specific inclusion criterion. • For Part B, an additional time point for laboratory assessment was added to Day 22. • Alcohol use during the duration of the study was updated in Exclusion Criteria for Parts A, B, and C. Additionally, clarified that the use of herbal supplements was prohibited during the study.

    Interruptions (globally)

    Were there any global interruptions to the trial? Yes
    Date
    Interruption
    Restart date
    06 Oct 2017
    The study was terminated as part of a business decision to advance a new HBV development candidate and not due to any safety concerns. At the time of study termination all healthy volunteers had completed Part A, and postdosing safety monitoring was considered complete per the SRC.

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Only Part A of the study was completed. No subjects were enrolled in Parts B and C, which were to include subjects with HBV infection. Therefore, the efficacy endpoint of hepatitis B surface antigen (HBsAg) levels could not be assessed.
