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   42312   clinical trials with a EudraCT protocol, of which   6968   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

    General information about the trial
    Main objective of the trial
    To evaluate the safety and tolerability of IRL752 after repeated dosing in patients with Parkinson’s Disease Dementia (PDD).
    Protection of trial subjects
    The ICF included information that data would be recorded, collected and processed and could be transferred to European Economic Area (EEA) or non-EEA countries. In accordance with the EU Data Protection Directive (95/46/EC), the data would not identify any patients taking part in the study. The potential study patient (and/or LAR, as applicable) and his/her caregiver were informed that by signing the ICF he/she/they approved that authorized representatives from Sponsor and CTC Clinical Trial Consultant AB (CTC), the concerned IEC and CA had direct access to his/her medical records for verification of clinical study procedures. An authorization from the hospital for access to medical records by the Monitor was available, as required by local legislation. The patient had the right to request access to his/her personal data for rectification of any data that was not correct and/or complete. The Investigator filed a Patient Identification List, which included sufficient information to link records, i.e. the eCRF and clinical records. This list will be preserved for possible future inspections/audits but has not been made available to the Sponsor except for monitoring or auditing purposes.
    Background therapy
    Patients included in the study had to be on stable anti-Parkinson treatment for at least 30 days prior to inclusion and during the study. Treatment with Selegiline was not allowed. Concomitant treatment with pro-cognitive treatments such as Ach esterase inhibitors and Memantine were allowed.

    The objective was to evaluate the effects of IRL752 on neuropsychiatric symptoms assessed with Neuropsychiatric Inventory-12 (NPI-12), as compared to placebo. The NPI-12 is a clinical instrument for assessing behavioural and psychological symptoms in dementia in 12 domains [13]. It is based on an interview with the primary caregiver. Each NPI domain is scored by the caregiver based on a standardized interview administered by the clinician. Each domain is scored for frequency, severity and associated caregiver distress. A higher score represents a higher severity or caregiver distress. Data based on FAS population.

    The objective was to evaluate the effects of IRL752 on global function assessed with Clinician's Interview-Based Impression of Change Plus caregiver input (CIBIC-Plus), as compared to placebo. The CIBIC-Plus is a validated clinical instrument used to measure change in global function through an interview with patients and their caregivers. Patients are assessed on a 7-point scale, “1=Very much improved” to “7=Marked worsening”, based on information from four major categories: General, Mental/Cognitive State, Behaviour, and ADLs.
