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 evaluate the safety and efficacy of APX001 for the treatment of adult subjects aged 18 years and above with invasive mold infection (IMIs) caused by Aspergillus spp. or rare molds (e.g., Scedosporium spp., Fusarium spp., and Mucorales fungi), who have limited antifungal treatment options.
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Council for Harmonisation (ICH) Good Clinical Practice (GCP) Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were followed.

    Pre-assignment
    Screening details
    Study was planned to be conducted in two cohorts: Cohort A included subjects with invasive mold infections (IMA) and exploratory Cohort B planned to include subjects with invasive aspergillus, who had COVID-19 or Influenza A/B. Study was terminated early; no subjects were enrolled in Cohort B; hence data is not reported for Cohort B in any section.

    Arm description
    Eligible subjects aged 18 years or older with invasive mold infections (IMI) and limited antifungal treatment options were included in this arm. On Day 1, subjects received APX001 1000 milligram (mg) as a loading dose over 3 hours by intravenous (IV) infusion twice daily (BID). On Days 2 and 3, subjects received APX001 600 mg as maintenance dose over 3 hours by IV infusion once daily (QD). From Day 4 till end of study treatment, for maintenance dose subjects received either APX001 600 mg IV infusion QD over 3 hours or switched to APX001 800 mg orally QD on investigator discretion. Total treatment duration was maximum of 42 days. Subjects had a follow-up visit at 4 weeks after last dose of study treatment and a follow-up telephone call was required on Day 84.

    Global response was classified as treatment success (complete or partial response [CR or PR]) or treatment failure (stable response [SR], progression of fungal disease [PD], or death) as determined by DRC. CR: resolution of all attributable symptoms and signs of disease and radiological (rad) abnormalities, and mycological (myco) evidence of eradication of disease. PR: improvement in attributable symptoms and signs of disease and rad abnormalities, and evidence of clearance of cultures or reduction of fungal burden. SR: minor or no improvement in fungal disease, but no evidence of progression, based on a composite of clinical, rad, and myco criteria, PD or death. PD: evidence of progressive fungal disease based on a composite of clinical, rad, and myco criteria. CR, PR and PD: survival within prespecified period of observation. Death: death during prespecified period of evaluation, regardless of attribution. End point analysed in mITT population.

    An adverse event was any untoward medical occurrence in a subject who received study treatment without regard to possibility of causal relationship. TEAEs were events between first dose of study treatment and up to 4 weeks post last dose of study treatment that were absent before treatment or that worsened relative to pretreatment state. An SAE was any untoward medical occurrence that occurred, at any dose: resulted in death; required inpatient hospitalisation or prolongation of existing hospitalisation; was life-threatening; resulted in persistent or significant disability/ incapacity; was a congenital anomaly/birth defect and other important medical events. AEs included SAEs and all non-SAEs. Safety population included all subjects who received at least 1 dose of study drug.
