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   43977   clinical trials with a EudraCT protocol, of which   7312   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.

    6 behavioral/cognitive symptoms required for a diagnosis of possible bvFTD, or a diagnosis of PPA (symptomatic participants).

    General Inclusion Criteria:
    2. Presymptomatic participants (with a global CDR® plus NACC FTLD score of 0) are 45 to 85 years of age, inclusive, at screening, or symptomatic participants (with a global CDR® plus NACC FTLD score of 0.5,1, or 2) are 25 to 85 years of age, inclusive, at screening
    3. At screening, female participants must be nonpregnant and nonlactating, and 1 of the following conditions must apply:
    a. Participant is not a woman of childbearing potential (WOCBP) (either surgically sterilized or physiologically incapable of becoming pregnant, or at least 1-year postmenopausal [amenorrhea duration of 12 consecutive months with no identified cause other than menopause]).
    b. Participant is a WOCBP and agrees to use an acceptable contraceptive method from screening until 10 weeks after the last dose of study treatment. Acceptable contraception is defined as using hormonal contraceptives (e.g. combined oral contraceptive pill) or an intrauterine device combined with at least 1 of the following forms of contraception: a diaphragm or cervical cap, or a condom. In addition, total abstinence, in accordance with the lifestyle of the participant, is acceptable.
    A WOCBP must have a serum pregnancy test conducted at screening. Additional requirements for pregnancy testing during and after study intervention are described in the Schedules of Assessments.
    4. Male participants must agree to use acceptable contraception and not donate sperm from Day 0 until 10 weeks after the last dose of study treatment. Acceptable contraception for the male participant when having sexual intercourse with a WOCBP who is not currently pregnant is defined as using a condom. In addition, WOCBP partners must use hormonal contraceptives (e.g. combined oral contraceptive pill) or an intrauterine device.
    5. Participant agrees not to donate blood or blood products for transfusion for the duration of the study and for 1 year after the final dose of study treatment.
    6. Participant is willing to and can comply with the study protocol requirements, in the opinion of the investigator.
    7. Participant is willing and able to give informed consent. If the study participant is not competent, a legally authorized representative must provide informed consent on their behalf, and the participant must provide assent, in accordance with the local regulations, guidelines, and institutional review board (IRB) or independent ethics committee (IEC).
    8. Participant has availability of a person (“study partner”) who has frequent and sufficient contact with the participant (at least 5 hours per week of in-person contact), can provide accurate information regarding the participant’s behavior, cognitive, and functional abilities as well as their health throughout the study, agrees to provide information at investigational site visits that require partner input for COA completion, and gives the necessary informed consent.
    a. Pre-symptomatic participants (global CDR® plus NACC FTLD score of 0) require
    the study partner at the COA visits only; symptomatic participants require the
    study partner at each visit. Pre-symptomatic participants who become symptomatic
    (global CDR® plus NACC FTLD score of 0.5 or greater) during the study treatment period require the study partner at each visit moving forward through Study Completion.
    b. The study partner must have sufficient cognitive capacity to accurately report upon the participant’s behavior, cognitive, and functional abilities in the opinion of the investigator. The study partner should be in sufficiently good general health to
    have a high likelihood of maintaining the same level of interaction with the participant and participation in study procedures throughout the study duration.
    c. The same study partner should participate throughout the duration of the study. If a change in study partner is necessary, the Medical Monitor must be contacted.
    E.4Principal exclusion criteria
