NCT04301284

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

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

    Incidence of Adverse Events

    12 week treatment period

Study Arms (2)

CAD-1883

EXPERIMENTAL

Capsules 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.

Drug: CAD-1883

Placebo

PLACEBO COMPARATOR

Matching placebo will be provided in capsules, to be administered orally, twice daily. The second daily dose will be taken 8 hours (+/- 2 hours) after the first daily dose.

Drug: Placebos

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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
  • SARA item #1 (gait) score of ≥2 at Screening
  • Ability to ambulate 8 meters at Screening without assistance from another person

You may not qualify if:

  • 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).
  • Moderate or severe scores on the following Inventory of Non-Ataxia Signs (INAS) items at Screening: Dystonia: at least 3 of 5 items; Spasticity: at least 2 of 3 items; Rigidity: at least 2 of 3 items
