Trial Outcomes & Findings for Flexible-Dose Trial in Early Parkinson's Disease (PD) (NCT NCT04223193)
NCT ID: NCT04223193
Last Updated: 2025-11-21
Results Overview
The Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) rating tool was used to follow longitudinal course of Parkinson's Disease. It was made up of 4 parts: Part 1: Non-motor aspects of experiences of daily living (13 items. Score range: 0-52); Part 2: Motor aspects of experiences of daily living (13 items. Score range: 0-52); Part 3: Motor examination (18 items. Score range: 0-132); Part 4: Motor complications (6 items. Score range: 0-24. Part 4 was not collected in this trial). Each item has 0-4 rating on scale from 0 (normal) to 4 (severe). Higher values represent a worse outcome. A negative change from baseline represents an improvement in motor function. Parts 2 and 3 combined is the sum of Part 2 score and Part 3 score at each assessment time for each participant. The combined score assesses 31 items with score range: 0-184.

The Patient Global Impression of Change (PGIC) is a 7-point response scale. The participant response to the question, "Compared to your condition at the beginning of treatment, how much has your condition changed?" was assessed. Scores ranged from 1-7 on a scale of 1 (very much improved) to 7 (very much worse). Higher values represent a worse outcome.

The Global Impression - Severity of Illness (CGI-S) Score is a clinician's impression of a participant's severity of illness on a 7-point scale. Scores ranged from 1-7 on a scale of 1 (normal) to 7 (among the most extremely ill participants). Higher values represent a worse outcome.

The Clinical Global Impression - Improvement (CGI-I) Score is a clinician's impression of how much the participant's illness has improved or worsened relative to the baseline on a 7-point scale. Scores ranged from 1-7 on a scale of 1 (very much improved) to 7 (very much worse). Higher values represent a worse outcome.

The Patient Global Impression of Change (PGIC) is a 7-point response scale. The participant response to the question, "Compared to your condition at the beginning of treatment, how much has your condition changed?" was assessed. Scores ranged from 1-7 on a scale of 1 (very much improved) to 7 (very much worse). Higher values represent a worse outcome.

The ESS is an 8-question, participant questionnaire that is intended to measure daytime sleepiness. It assesses the likelihood of dozing off or falling asleep in the following common situations: sitting and reading, sitting inactive in a public place as a passenger in a car for an hour or more without stopping for a break, lying down to rest when circumstances permit, sitting and talking to someone, sitting quietly after a meal without alcohol, and in a car while stopped for a few minutes in traffic or at a light. Each situation is rated on a 4-point (0-3) scale with scores ranging from 0 (would never nod off) to 3 (high chance of nodding off). Higher values represent a worse outcome. A negative change from baseline represents an improvement in daytime sleepiness. The total ESS score range was 0 - 24.

QUIP-RS is a questionnaire for impulse-compulsive disorders in Parkinson's disease rating scale to assess impulse control disorders (ICD). The QUIP-RS has 4 primary questions that pertain to commonly reported thoughts, urges/ desires, and behaviors associated with ICDs, each of which is applied to 4 ICDs (compulsive gambling, buying, eating, sexual behavior) and 3 related disorders (medication use, punding, and hobbyism). The QUIP-RS uses a 5-point Likert scale (score 0-4 \[0 means "never" and 4 means "very often"\] for each question) to gauge the frequency of behaviors. Scores for each ICD and related disorder range from 0 to 16, with a higher score indicating greater severity (frequency) of symptoms. The total QUIP-RS score for all ICDs and related disorders combined ranges from 0 to 112. A higher score indicating greater severity of symptoms. A negative change from baseline represents an improvement in ICDs.

The C-SSRS is a systematically administered instrument developed to track suicidal adverse events across a treatment study. The instrument is designed to assess suicidal behavior and ideation, track and assess all suicidal events, as well as the lethality of attempts. Suicidal ideation (SI) categories include the following: wish to be dead; nonspecific active suicidal thoughts; active suicidal ideation without intent to act; active suicidal ideation with some intent to act but no plan; active suicidal ideation with plan and intent. Suicidal behavior categories include the following: actual attempt; interrupted attempt; aborted attempt; preparatory acts or behavior; suicidal behavior; completed suicide.

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study drug. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of study drug.
