Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   39361   clinical trials with a EudraCT protocol, of which   6446   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).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Subjects must meet all of the following criteria to be eligible for enrollment into the study:
    1. Currently enrolled and have not been discontinued from pexidartinib treatment in one of the following studies: Study PLX108-10 (ENLIVEN), Study PLX108-01, Study PL3397-A-A103, or Study PL3397-A-U126.
    2. Willing and able to complete the PROMIS (Physical Function Scale) and EQ-5D-5L (European Quality of Life) throughout the study.
    3. Willing and able to provide written informed consent form (ICF) prior to any study-related procedures and to comply with all study requirements.
    4. Females of reproductive potential must have a negative urine pregnancy test at Screening/Baseline (to be confirmed by a serum pregnancy test taken on the End-of-Treatment visit of their prior study) and should be advised to use an effective, non-hormonal method of contraception during treatment with pexidartinib and for 1 month after the last dose. Males with female partners of reproductive potential should be advised to use an effective method of contraception during treatment with pexidartinib and for 1 month after the last dose. Female partners of male patients should concurrently use effective contraceptive methods (hormonal or non-hormonal).
    Note: A female is considered of reproductive potential following menarche and until becoming postmenopausal (no menstrual period for a minimum of 12 months) unless permanently sterile (undergone a hysterectomy, bilateral salpingectomy or bilateral oophorectomy) with a confirmed by follicle stimulating hormone (FSH) test level >40 mIU/mL.
    5. Male subjects must not freeze or donate sperm starting at Screening and throughout the study period, and for at least 5 half-lives or 1 month after the final study drug administration, whichever is longer.
    Female subjects must not donate, or retrieve for their own use, ova from the time of Screening and throughout the study treatment period, and for at least 1 month or 5 half-lives after the final study drug administration, whichever is longer.
    E.4Principal exclusion criteria
    Subjects who meet any of the following criteria are NOT eligible for enrollment into the study
    1. Subject has a clinically significant abnormality identified by the Investigator at Screening on physical examination, laboratory tests, or electrocardiogram which, in the judgement of the Investigator, would preclude the subject’s safe completion of the study.
    2. Exposure to another investigational drug or current participation in other therapeutic investigational procedures, besides pexidartinib studies, within 1 month prior to start of study treatment. Any known contraindication to treatment with, including hypersensitivity to, the study drug(s) or excipients in pexidartinib.

    Change from Baseline in Patient Reported Outcomes (PROs): every 3 months

    - Incidence of AEs/TEAEs and SAEs: after subject signs the ICF and up to 30 days after the last dose of study medication
    - ECGs: at screening/baseline and at EOS/EOT/FU (and whenever deemed medically necessary)
    - laboratory assessments - from baseline, every study visit until EOS/EOT/FU; only for Treatment Free Period: at baseline and then every 6 months until EOS/EOT/FU
