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   43801   clinical trials with a EudraCT protocol, of which   7272   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.1.1Medical condition(s) being investigated
    Frontotemporal Dementia and related syndromes

    Prevention and reversal of tau protein aggregation is a novel approach to the treatment of patients with FTD and related syndromes and has the potential for slowing the disease process as well as providing symptomatic improvement in hitherto untreatable, ultimately fatal conditions.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of the study is to investigate and compare the effects of oral MTC at a dose of 100 mg tid on cognitive ability in patients with frontotemporal dementia with Parkinsonism linked to chromosome 17, frontotemporal dementia (lacking evidence of dominant inheritance), progressive aphasia (semantic dementia and progressive non-fluent aphasia), and corticobasal degeneration or progressive supranuclear palsy associated with dementia.

    Cognitive ability will be measured by the Cambridge Cognitive Examination (CAMCOG). Interim evaluations will be made at 12 weeks (visit 2), 24 weeks (visit 4), and the final evaluation will be made at 48 weeks (Visit 6).
    E.2.2Secondary objectives of the trial
    1. The secondary objectives of this study are to investigate the effects of MTC on:

    (i) Behavioural and psychological symptoms assessed on the Neuropsychiatric Inventory (NPI).
    (ii) Global state assessed on a clinical global impression / of change (CGI/C).
    (iii) Functional ability assessed on the Bristol Activities of Daily Living Scale (BADLS).
    (iv) Extrapyramidal symptoms and signs assessed on the Short Parkinson’s Evaluation Scale (SPES).

    2. Cerebral perfusion assessed by hexamethylpropylamine oxime single photon emission computerised tomography (HMPAO SPECT) scan.

    3. Cerebral atrophy assessed by MRI.

    4. The safety and tolerability of MTC will also be evaluated.
    E.2.3Trial contains a sub-study Information not present in EudraCT
    E.3Principal inclusion criteria
    1. Patients of either sex supervised by a carer competent and willing to ensure compliance with medication and who is willing to participate in completing the various assessments.

    2. Female patients should not be pregnant at the start of the study or planning a pregnancy during the course of the study.

    3. Patients must be able to either give written informed consent to participation in the study, with additional assent to their participation being provided by a competent carer.

    4. Patients must meet either:

    • Consensus Clinical Diagnostic Criteria for Frontotemporal Lobar Degeneration (Neary et al 1998) including MRI and HMPAO SPECT imaging consistent with the diagnosis
    • NINDS –SPSP Clinical Criteria for Diagnosis of Probable Progressive Supranuclear Palsy including MRI and HMPAO SPECT imaging consistent with that diagnosis (Litvan et al 1996a)
    • Diagnostic Criteria for Corticobasal Degeneration including MRI and HMPAO SPECT consistent with the diagnosis (Boeve et al 2003)

    In addition to meeting the above criteria patients additionally must have significant cognitive impairment with a CAMCOG score of < 85.
    E.4Principal exclusion criteria
    The patient is not eligible to participate in the study in any of the following circumstances:

    1. The patient has a known sensitivity to MTC or similar agents.

    2. The patient has known glucose-6-phosphate dehydrogenase deficiency.
    3. The patient has known hereditary methaemoglobinaemia, has been known to have suffered an attack of acquired methaemoglobinaemia or has a blood level of methaemoglobin at screening which is above the upper limit of normal for age and laboratory.

    4. The patient has significant impairment of renal, hepatic or haematological function for the age of the patient.

    5. The patient has started taking prescribed medication known to have an effect on mood, cognition or motor function within the previous six weeks or has changed the dose of such medication within the same period (e.g.cholinesterase inhibitors, memantine, anticholinergics, hypnotics, sedatives, anxiolytics, neuroleptics antidepressants, antiepileptics or antiparkinsonian drugs).

    6. The patient has started taking an alternative anti dementia therapy (e.g. ginkgo biloba or HRT) within six weeks or has changed their dose within that period.

    7. The patient is receiving warfarin or digitalis or any other medication that has a narrow margin between effective dose and toxic dose or between effective dose and ineffective dose, where the subject would be at risk if the levels were to rise or fall due to interaction with MTC.

    8. Patients who are unlikely to comply with the study procedures or with study medication.

    9. Patients with significant intercurrent illness which in the opinion of the investigator may compromise either the safety of the patient or the validity of the data.

    10. Females who, in the opinion of the investigator, have the potential of childbearing and are not using adequate contraception or females who are breastfeeding.

    11. Patients with a history of alcohol or drug abuse defined as meeting DSM-IV criteria for substance dependence. This applies to alcohol and /or any illicit drug including cannabis within the last six months.

    12. The patient has participated in a clinical investigation of a medication or device within the previous three months.
    E.5 End points
    E.5.1Primary end point(s)
    The primary objective of the study is to investigate and compare the effects of 100 mg tid oral MTC on cognitive ability in patients with FTD or related dementias.
    Change in cognitive ability from baseline to week 48 will be measured by the Cambridge Cognitive Examination (CAMCOG).

    Secondary objectives of the study are to investigate the bahavioural and pschological symtoms assessed on the NPI, clobal sate assessed on the CGI/C, functional ability assessed on the BADLS, extrapyramidal symptoms and signs assessed on the SPES, cererebral perfusion assessed by SPECT.
