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   44338   clinical trials with a EudraCT protocol, of which   7368   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
    The purpose of this study was to determine whether LFG316 can induce a hematological response, as measured by reduction in hemolytic activity, in patients with paroxysmal nocturnal hemoglobinuria (PNH).
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. All the local regulatory requirements pertinent to safety of trial subjects were also followed during the conduct of the trial.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    08 May 2015
    The main purpose of this amendment was to address a Health Authority request to amend inclusion criterion #7. The amendment specified that treatment with LFG316 may only be initiated at the earliest 2 weeks after meningococcal vaccination. The previous wording allowed the administration of study drug immediately after vaccination, provided that prophylactic antibiotics were used for at least 2 weeks. Other changes included clarifications and changes to wording, and minor corrections and corrections for typographical errors.
    23 Jun 2015
    The main purpose of this amendment was to address a request from the Health Authority of the Czech Republic to lower the maximum age of patients eligible for participation in this clinical study from 75 to 65 years of age in the Czech Republic. A requirement for close medical supervision at the study site during the infusion time of LFG316 and up to 2 hours after the end of the infusion during Treatment Period 1 was included.
    30 Jun 2015
    The main purpose of this amendment was to address clarification requests from the Health Authority of Japan with regards to vaccination requirements, safety follow-up, and safety measures in case of specific adverse events (e.g., infusion reactions).
    21 Oct 2015
    The main purpose of this amendment was to extend the screening period from 28 to 60 days to enable and comply with local recommendations for vaccination whenever available and if deemed necessary at investigator’s discretion. Inclusion Criterion #2 was modified by removing the time limit from the moment of diagnosis of PNH (i.e., 6 months). Based on the chronicity of the disease, the certainty of the diagnosis, and investigators feedback, the 6 months were not deemed necessary to define eligibility of the patients. Clarifications on Exclusion Criterion #09 and #10 were added. Minor corrections and clarifications were made.
    15 Jun 2016
    The main purpose of this amendment was to ensure a seamless continuation of treatment in LFG316-responsive patients already enrolled in the study, and to continue to assess long term safety, efficacy, pharmacokinetic and pharmacodynamic data beyond 48 weeks. The study design was updated with the addition of extension period 3. Additional changes were made to reduce patients’ burden and to clarify exclusion criteria.
    21 Sep 2017
    The main purpose of this amendment was to allow recruitment of up to approximately five additional PNH patients who were refractory to eculizumab therapy due to a genetic variant leading to amino acid exchange (Arg885His) in the C5 protein, due to a lack of effective treatment options in this subpopulation of PNH patients. The upper age limit was removed to allow older variant patients to participate in the study. To date, patients up to 82 years old were safely treated with LFG316 and considering lack of any treatment options it is deemed justified to allow treatment of older PNH patients. As there were no safety concerns in study CLFG316B2102 in healthy volunteers infused over 30 and 60 minutes, it was considered appropriate to decrease the required infusion time in Periods 2 and 3 from approximately 2 hours to a minimum of 40 minutes.
    05 Mar 2019
    The main purpose of this amendment was to stop the recruitment into the trial, and to extend the study treatment for currently enrolled patients beyond the 3rd year in period 3. The assessment schedule reflects a reduced number of study visits and assessments during the extended period 3 with focus on safety assessments as the reason for this amendment is to secure extended LFG316 treatment access for patients currently enrolled in the trial. In addition, updated guidance about consent, withdrawal and early study termination is provided.
    15 Dec 2020
    The main purpose of this amendment was to convert ongoing study patients from LFG316 to LNP023, a potent, selective and reversible low molecular weight Factor B (FB) inhibitor for oral administration and allow them to be considered for participation in an open label extension study with LNP023 (CLNP023C12001B). Treatment period 4 was implemented to convert patients with PNH receiving i.v. LFG316 to oral LNP023. As per strategic decision, further development of LFG316 was terminated in favor of LNP023, Novartis offered patients enrolled in study CLFG316X2201 a conversion from LFG316 to LNP023, aiming to provide uninterrupted treatment for these PNH patients. With a protocol amendment, study Period 4 was implemented to allow patients to first convert from LFG316 to LNP023 therapy and then to join the separate LNP023 roll-over extension study CLNP023C12001B.

    Interruptions (globally)

    Were there any global interruptions to the trial? No

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    LFG316 development was terminated in favor of LNP023. CLFG316X2201 patients were offered conversion from LFG316 to LNP023 for uninterrupted treatment.
