What is being measured

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

  1. Assess the effect of two doses of safinamide on reducing levodopa-induced dyskinesia

    Change from Baseline to Week 26 in levodopa-induced dyskinesia based on UDysRS total score. The UDysRS is a dyskinesia rating scale from 0-104; it evaluates involuntary movements associated with PD. A higher score indicates more severe PD

    Measured: 26 weeks

Secondary outcomes (9)
  1. Assess the effect of two doses of safinamide on ON time with No Dyskinesia

    Change from Baseline (Day 1 prior to start of study intervention) to Week 26 total daily ON time with No dyskinesia based on PD Home Diary. A PD home diary is used to score 5 different conditions : ASLEEP, OFF, ON (ie, had adequate control of PD symptoms) without dyskinesia, ON with non-troublesome dyskinesia, and ON with troublesome dyskinesia.

    Measured: 26 weeks

  2. Assess the effect of two doses of safinamide on ON time with non-troublesome dyskinesia

    Change from Baseline (48 hours prior to Day 1) to Week 26 based on PD Home Diary in total daily ON time with non-troublesome dyskinesia. A PD home diary is used to score 5 different conditions : ASLEEP, OFF, ON (ie, had adequate control of PD symptoms) without dyskinesia, ON with non-troublesome dyskinesia, and ON with troublesome dyskinesia.

    Measured: 26 weeks

  3. Assess the effect of two doses of safinamide on ON time with troublesome dyskinesia

    Change from Baseline (48 hours prior to Day 1) to Week 26 based on PD Home Diary in total daily ON time with troublesome dyskinesia. A PD home diary is used to score 5 different conditions : ASLEEP, OFF, ON (ie, had adequate control of PD symptoms) without dyskinesia, ON with non-troublesome dyskinesia, and ON with troublesome dyskinesia.

    Measured: 26 weeks

  4. To assess the effect of two doses of safinamide on ON time with any dyskinesia (troublesome or non-troublesome)

    Change from Baseline (48 hours prior to Day 1) to Week 26 based on PD Home Diary in total daily ON time with any dyskinesia (troublesome or non-troublesome). A PD home diary is used to score 5 different conditions : ASLEEP, OFF, ON (ie, had adequate control of PD symptoms) without dyskinesia, ON with non-troublesome dyskinesia, and ON with troublesome dyskinesia.

    Measured: 26 weeks

  5. To assess the effect of two doses of safinamide on sleep time

    Change from Baseline (48 hours prior to Day 1) to Week 26 based on PD Home Diary in total daily sleep time. A PD home diary is used to score 5 different conditions : ASLEEP, OFF, ON (ie, had adequate control of PD symptoms) without dyskinesia, ON with non-troublesome dyskinesia, and ON with troublesome dyskinesia.

    Measured: 26 weeks

  6. To assess the effect of two doses of safinamide on Movement Disorder Society-Sponsored Unified Parkinson's Disease Rating Scale (MDS-UPDRS) total score and sub-scores

    Change from Baseline (Day 1 prior to start of study intervention) to Week 26 in MDS-UPDRS total score and sub-scores. The MDS-UPDRS is divided into 4 parts. In each part, all items are rated on a scale from 0 (normal) to 4 (severe impairment); Part I assesses 15 items of non-motor aspects of experiences of daily living; Part II comprises 13 items evaluating the impact of PD on patients' activities of daily living (ADL) over the week prior to the visit such as speech, salivation, swallowing, eating, handwriting, dressing, turning in bed, walking; part III assesses the motor abilities in PD patients at the time of the visit; Part IV assesses motor complications of therapy, such as dyskinesias, motor fluctuations.

    Measured: 26 weeks

  7. To assess the effect of two doses of safinamide on Clinician Global Impression of Change (CGIc)

    Clinician Global Impression of Change (CGIc) at Week 26. CGI-C is a 7-point scale used by Investigator to rate patient's overall improvement using a range of responses from 1 (very much improved) through to 7 (very much worse).

    Measured: 26 weeks

  8. To assess the effect of two doses of safinamide on Patient Global Impression of Change (PGIc)

    Patient Global Impression of Change (CGIc) at Week 26. PGI-C is a 7-point scale depicting a patient's rating of overall improvement using a range of responses from 1 (very much improved) to 7 (very much worse).

    Measured: 26 weeks

  9. To assess the effect of two doses of safinamide on PDQ-39 summary index

    Change from Baseline (Day 1 prior to start of study intervention) to Week 26 in PDQ-39 summary index. The PDQ-39 is a specific tool to assess quality of life in PD. Comprises 39 items divided into eight dimensions: mobility, activities of daily living (ADLs), emotional well-being, stigma, social support, cognition, communication and physical discomfort, where scores range from 0-100, with the higher, the worse the perception of quality of life.

    Measured: 26 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Safinamide Methanesulfonate 150mg and Safinamide Methanesulfonate 100mg in people with Dyskinesia, Drug-Induced and Parkinson Disease, run by Zambon SpA.

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 9 inclusion and 15 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: withdrawn, as of the sponsor's last update on 17 Jun 2020. 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 phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 was withdrawn before enrolling participants, so there are no results.

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?

Assess the effect of two doses of safinamide on reducing levodopa-induced dyskinesia (time frame: 26 weeks). 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 17 Jun 2020.
