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   44334   clinical trials with a EudraCT protocol, of which   7366   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.

    E.2.2Secondary objectives of the trial
    Clinical global assessment of overall severity of symptoms
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Procedures:
    1.Able to understand and provide signed informed consent, and must be able to sign and date a request for medical records and/or subject privacy form, if applicable, according to local regulations
    2.Has a caregiver or some other identified responsible person (e.g., family member, social worker, caseworker, or nurse) considered reliable by the Investigator in providing support to the subject to help ensure compliance with study treatment, study visits, and protocol procedures and who is also able to provide input helpful for completing study rating scales
    3.Is completing the Week 6 visit in Study ACP-103-034 or the Week 26 visit in Studies ACP-103-038 or-64 while continuing to take his/her assigned dose of blinded study drug and may, in the Investigator’s opinion, benefit from continued adjunctive treatment with pimavanserin to an antipsychotic
    Medical Status:
    4.If the subject is female, she must not be pregnant or breastfeeding. She must also be of non-childbearing potential (defined as either surgically sterilized or at least 1 year postmenopausal) or must agree to use two clinically acceptable methods of contraception or be abstinent

    religious, legal, or health reason. If heterosexual intercourse does occur, two acceptable methods of birth control are required. Acceptable method
    of contraception include the following:
    a. A barrier method (condom, diaphragm, or cervical cap) with spermicide
    b. Hormonal contraception, including oral, injectable, transdermal, or implantable methods
    c. Intrauterine device (IUD)
    Only one of the two clinically acceptable methods can be a hormonal method.
    •All female subjects of childbearing potential must have a negative urine human chorionic gonadotropin (hCG) pregnancy test at Baseline and at Weeks 2, 6, 12, 20, 28, 36, 44, and 52

    has a QRS interval ≥120 ms and QTcF ≥480 ms at Baseline
