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 primary objective was to assess the efficacy of LTP001 in participants with pulmonary arterial hypertension (PAH). Due to EudraCT system limitations, which EMA is aware of, data using 999 as data points in this record are not an accurate representation of the clinical trial results. Please use https://www.novctrd.com/CtrdWeb/home.nov for complete trial results.
    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.

    End point description
    Key right ventricular (RV) function per echocardiography. The terms Tricuspid Annular Systolic Velocity (TASV) and Peak Velocity of Excursion (RV S’) are synonymous in echocardiography to describe the peak systolic velocity of the lateral tricuspid annulus. Including both TASV and RV S’ as separate secondary endpoints was an oversight in the protocol as the data, calculation, and analyses for both (TASV and RV S’) are identical. Therefore, the TASV nomenclature is used in this results disclosure

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    01 Dec 2021
    This amendment: required a negative serum pregnancy test within 7 days prior to first dose administration on Day 1 to rule out pregnancy where required by health authority (e. g., the United Kingdom) or local regulations. In countries where this was not required, a negative urine pregnancy test needed to be available prior to dosing on Day 1; excluded participants who took strong CYP3A4/5 inducers or inhibitors; excluded participants who had a long QT syndrome or who took drugs known to prolong the QT interval; added strong CYP3A4/5 inducers, strong CYP3A4/5 inhibitors, and known drugs which cause QT prolongation to the prohibited medications list; specified that 6MWT was only to be conducted on-site to remove testing variability in the assessment; removed the requirement for participants to record investigational medicinal product (IMP) dosing every day in the eDiary; specified that compliance for IMP administration was to be done by medication reconciliation; added coagulation assays (PT, INR, aPTT) and luteinizing hormone and follicle stimulating hormone (FSH) to the safety laboratory panel.
    02 Mar 2022
    This amendment: updated clinical safety data; added guidance text for 6MWT and multi-sensor device; updated withdrawal of consent language to improve clarity.
    01 Nov 2022
    This amendment: incorporated language regarding the implementation of a data monitoring committee (DMC); updated exclusion criteria with information about sperm donation to reflect the requirements described in the protocol appendix; updated protocol appendix with further guidance details for hepatic and renal alert criteria and event follow-up; updated protocol appendix with considerations about the use of LTP001 in combination with allowed standard therapies.

    Interruptions (globally)
    Were there any global interruptions to the trial? No
