About this study

Official title: A Randomised, Double-blind, Placebo-controlled, Phase Ib Study Evaluating the Safety and Tolerability of IRL790 in Patients With Parkinson's Disease (PD) Experiencing Levodopa (L-Dopa) Induced Dyskinesia (LID).

This is a Phase 1b study investigating the safety and tolerability of IRl790 as adjunct therapy in patients with Parkinson disease. IRL790/placebo is taken for 28 days.

Read the detailed description

Consenting patients were screened for eligibility as per study-specific inclusion/exclusion criteria within 8-28 days before start of Investigational Medicinal Product (IMP) administration (Visit 1; Screening Visit). At Visit 2 (Day -7) a kinetigraph device (the Parkinson's KinetiGraph™, Global Kinetics Corporation, Melbourne, Victoria, Australia) was attached to the right or left wrist (the parkinsonian dominant side) and baseline patient movement data were recorded during a run-in period of seven consecutive days.

Following baseline assessments at Visit 3 (Day 1) patients were randomized to receive IRL790 or placebo (3:1). The treatment allocation was double-blinded, i.e. it was not disclosed to the patients, the site staff or the Sponsor. During the treatment period, Visits 4-8 were performed on Days 4, 7, 10, 14 and 28 (end of treatment) and a follow-up phone call was performed on Day 21. Dose adjustments of IRL790 could be made until Day 14, following pre-defined criteria. A follow-up visit (Visit 9) was performed 7-10 days after the last IMP dose.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Adverse Events

    Medical Dictionary for Regulatory Activities Preferred Term

    Measured: 4 weeks

  2. Physical examination

    Number of participants with clinically significant abnormal physical examination findings

    Measured: 4 weeks

  3. Electrocardiogram (ECG) recordings

    Number of participants with clinically significant abnormal electrocardiogram readings

    Measured: 4 weeks

  4. Heart rate

    Beats per minute

    Measured: 4 weeks

  5. Blood pressure

Secondary outcomes (6)
  1. Unified Dyskinesia Rating Scale (UDysRS)

    The change from baseline to day 28 of treatment (Visit 4) in the sum of the items comprising the Unified Dyskinesia Rating Scale (UDysRS). The UDysRS is administered to assess dyskinesia. The scoring range is 0-104, where higher score means more dyskinesia.

    Measured: 4 weeks

  2. Unified Parkinson's Disease Rating Scale (UPDRS)

    The UPDRS assess symptoms of Parkinson's disease. The scoring range from 0-199, where higher score means more severe disease.

    Measured: 4 weeks

  3. Parkinson Kinetigraph (PKG)

    Wrist worn kinetigraph capturing electronic readings of movement activity.

    Measured: Change from run-in to week 4 of treatment

  4. Clinical Global impression of change (CGI-C)

    Global impression of change

    Measured: 4 weeks

  5. Pharmacokinetic assessment

    Measured: 4 weeks

  6. Pharmacokinetic assessment

    Trough level plasma concentration

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing IRL790 in people with Parkinson Disease, run by Integrative Research Laboratories AB.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 May 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse Events (time frame: 4 weeks). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2018.
