About this study

Official title: A Phase II, Randomized, Double-Blind, Placebo-Controlled, Multicenter Study of CVN424 in Parkinson's Disease Patients With Motor Fluctuations

This is a phase 2 study, randomized, double-blind, placebo-controlled, multicenter study of oral CVN424 at two dose levels (low-dose and high-dose) in Parkinson's disease (PD) patients with motor fluctuations.

Read the detailed description

Approximately 135 male and female subjects with Parkinson's disease, on a stable dosage of levodopa but with an average of ≥ 2 h total OFF time/day and not less than 1 h per day, will be enrolled. Following baseline safety and efficacy assessments, subjects will be randomized to receive once-daily doses of either low-dose CVN424, high-dose CVN424, or matching placebo. All subjects not randomized to placebo will initiate treatment with a low-dose of CVN424 on Day 1; the low-dose arm will continue to receive their low dose each day, while the high-dose arm will increase their daily dosage to the high-dose CVN424 beginning on Day 8 ±2 days and continuing thereafter. Study drug will be self-administered each morning as an oral suspension. Subjects will continue their other PD medications.

What is being measured

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

  1. Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) Related to Study Drug

    An adverse event is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. TEAEs are defined as any event with onset during or after the first dose of study treatment (active or placebo).

    Measured: Up to Day 35

Secondary outcomes (4)
  1. Percentage of Participants With Clinically Significant Abnormal Laboratory Parameters

    Blood and urine samples were collected for the analysis of laboratory parameters including clinical chemistry, hematology, and urinalysis. The investigator was responsible for reviewing laboratory results for clinically significant abnormalities.

    Measured: Up to Day 35

  2. Percentage of Participants With Clinically Significant Changes 12-Lead Electrocardiogram (ECG) Findings

    12-lead ECG recordings including heart rate and measured PR, QRS, QT, QT interval with Fridericia's correction method (QTcF) and QT interval with Bazett's correction method (QTcB) intervals. 12-lead ECG recordings were obtained after participants rested for at least 5 minutes in supine position. The investigator was responsible for reviewing laboratory results for clinically significant abnormalities.

    Measured: Up to Day 35

  3. Percentage of Participants With Clinically Significant Abnormal Vital Signs

    Vital signs including blood pressure (systolic and diastolic blood pressure), pulse rate, body temperature, respiratory rate and weight were measured after participants rested for at least 5 minutes in supine position. The investigator was responsible for reviewing laboratory results for clinically significant abnormalities.

    Measured: Up to Day 35

  4. Change From Baseline in 2-day Average OFF Time

    The Patient Motor Diary data (Hauser Diary) was completed by the participant to record the broad motor symptoms of pharmacodynamics. Categories included time asleep, OFF time, ON time without dyskinesia, ON time with non-troublesome dyskinesia, and ON time with troublesome dyskinesia. These diaries were collected for 24 hours on each of 2 consecutive days with records for every 30 minutes interval. The average daily OFF time was calculated from the records with reported OFF time. Baseline was defined as Day 0. Change from Baseline was defined as post Baseline minus Baseline value.

    Measured: Baseline and at Day 27

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CVN424 Low Dose and CVN424 High Dose in people with Parkinson Disease, run by Cerevance Beta, Inc. at 21 sites in United States.

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 4 inclusion and 17 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 3 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 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?

Yes. Results are posted in the registry (first posted 3 Jul 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) Related to Study Drug (time frame: Up to Day 35). 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 3 Jul 2024.
