Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 75 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Prior Spinocerebellar Ataxia (SCA) diagnosis of the following SCA genotypes: SCA1, 2, 3, 6, 7, 8, 10, 17, or Autosomal Recessive Cerebellar Ataxia Type 1 (ARCA1).
  • Scale for the Assessment and Rating of Ataxia (SARA) Total score ≥8 and <30 at Screening

Who cannot join

  • Neurological condition other than SCA that could predominantly explain or contribute significantly to the subjects' symptoms of ataxia or that could confound the assessment of ataxia symptoms (e.g., chronic alcoholism, vitamin deficiencies, multiple sclerosis, Parkinson's disease, Friedreich's ataxia, vascular disease, tumors, paraneoplastic disease, head injury, idiopathic late onset ataxia, multisystem atrophy, stroke, arthritis, cerebral palsy, spasticity of unknown origin).

About this study

Official title: Phase 2 Randomized, Double-blind, Placebo-controlled Study to Evaluate the Safety, Tolerability, and Efficacy of CAD-1883 in Adults With Spinocerebellar Ataxia (Synchrony-1)

This is a randomized, double-blind, placebo-controlled Phase 2 study evaluating oral administration of CAD-1883 in the treatment of adults with a genotypic diagnosis of Spinocerebellar Ataxia (SCA). This study offers the opportunity to understand the safety, tolerability, and efficacy of CAD-1883 in the SCA patient population.

Read the detailed description

This is a randomized, double-blind, placebo-controlled Phase 2 study evaluating oral administration of CAD-1883 in the treatment of adults with a genotypic diagnosis of SCA using multiple dose levels. The study will include multiple cohorts of 16 patients each where 12 patients will be randomized to CAD-1883 and 4 to matching placebo.

Potential subjects will undergo a screening period (14 to 28 days), a baseline (Day 1) visit, and a 12-week treatment period. A follow-up visit will occur 4 weeks after the end of the treatment period. The total duration of individual subject participation may be up to 20 weeks, depending on the duration of the screening period.

The study will assess safety by adverse events, vital signs, laboratory parameters (including chemistry, hematology and urinalysis); pharmacokinetics of CAD-1883; and efficacy measures by Scale for the Assessment and Rating of Ataxia (SARA), clinician/patient rating of ataxia and symptoms, patient quality of life measures and wearable sensors to capture falls and gait measurements.

For planning purposes, the anticipated study completion date assumes evaluation of 3 cohorts.

Study groupRoleWhat they receive
CAD-1883ExperimentalCapsules of 150 mg of CAD-1883 will be administered orally, twice daily (BID). The second daily dose will be taken 8 hours (+/- 2 hours) after the first daily dose. The initial dose regimen evaluated will be 150 mg BID. Additional dose regimens up to 600 mg BID will be determined based on forthcoming clinical data.

What is being measured

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

  1. To evaluate the safety and tolerability of oral administration of CAD-1883 versus placebo: Incidence of Adverse Events

    Incidence of Adverse Events

    Measured: 12 week treatment period

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CAD-1883 in people with Spinocerebellar Ataxias and Spinocerebellar Ataxia Type 1, run by Cadent Therapeutics at 6 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 2 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 8 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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?

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?

To evaluate the safety and tolerability of oral administration of CAD-1883 versus placebo: Incidence of Adverse Events (time frame: 12 week treatment period). 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 8 Apr 2021.
