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   43871   clinical trials with a EudraCT protocol, of which   7290   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 ).

    General information about the trial
    Main objective of the trial
    To assess the effect of LFG316 on the reduction of intravascular hemolysis in PNH patients.
    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.
    Background therapy
    This was an open-label, non-controlled study in patients with PNH, enrolling 10 patients and consisting of a screening period and 4 treatment periods as follows: A 60-day screening period was used to assess eligibility and to conduct vaccinations if required. Patients who met the eligibility criteria at screening entered treatment period 1 for baseline evaluation and received LFG316 infusion every 14 days for 4 weeks. Following assessment of efficacy (hemolytic activity by serum LDH) at the end of treatment period 1, patients entered the optional 48-week treatment period 2 and continued LFG316 infusions every 14 days. At the end of treatment period 2, LFG316-responsive patients (assessed based on the investigator’s judgment) were allowed to enter an additional extension period of up to 260 weeks (treatment period 3) in which they continued to receive LFG316 every 14 days. Period 4, which allowed patients to switch to LNP023, lasted approximately 21 weeks. During the first 4 weeks, patients continued to receive LFG316 in addition to oral administration of LNP023. After 4 weeks, patients discontinued LFG316 and continued with LNP023 monotherapy for approximately 16 weeks (± 28 days). Patients who participated in period 4 could join the long-term extension study CLNP023C12001B as soon as their eligibility was confirmed and study CLNP023C12001B was open to receive patients. There was no LNP023 treatment gap between the studies.

    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.

    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.

    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.
