Brief Summary:
This study seeks to evaluate the efficacy and safety of intepirdine (RVT-101) in patients with dementia with Lewy bodies.

Condition or disease Intervention/treatment Phase
Dementia With Lewy Bodies Drug: RVT-101 35 mg Drug: RVT-101 70 mg Drug: Placebo Phase 2

Detailed Description:

The efficacy and safety of RVT-101 at doses of 70 mg and 35 mg daily will be evaluated over a 24-week double-blind treatment period in patients with dementia with Lewy bodies.

The randomization ratio will be 1:1:1 (70 mg RVT-101: 35 mg RVT-101: placebo).

Subjects completing this study will be eligible to enroll in an extension study of RVT-101 (Study RVT-101-2002).

Primary Outcome Measures :
  1. Unified Parkinson's Disease Rating Scale-Part III (UPDRS-III) Change From Baseline at Week 24 [ Time Frame: Change from Baseline at 24 weeks ]
    The primary endpoint was to assess the effects of intepirdine versus placebo on the UPDRS Part III after 24 weeks of treatment. UPDRS Part III scores range from 0 to 108, with higher scores indicating worse outcome.


Secondary Outcome Measures :
  1. Alzheimer's Disease Assessment Scale - Cognitive Subscale 11 Items (ADAS-Cog-11) Change From Baseline at Week 24 [ Time Frame: Change from Baseline at 24 weeks ]
    The 11-item ADAS-Cog assesses a range of cognitive abilities including memory, comprehension, orientation in time and place, and spontaneous speech. The ADAS-Cog-11 total score range is from 0 to 70, with a higher score indicating more severe cognitive impairment.

  2. Clinician's Interview-Based Impression of Change Plus Caregiver Input (CIBIC+) Change From Baseline at Week 24 [ Time Frame: Change from Baseline at 24 weeks ]
    To assess the effects of RVT-101 versus placebo on global function as measured by the Clinician's Interview-Based Impression of Change Plus Caregiver Input (CIBIC+) after 24 weeks of treatment. CIBIC+ is recorded on a 7-point scale with a score of 4 indicating no change, scores above 4 indicating worsening, and scores below 4 indicating improvement.

Criteria

Inclusion Criteria:

  • Male or female subject with probable DLB
  • Mini Mental State Examination (MMSE) score of 14-26 inclusive at Screening and Baseline
  • Patient has the ability to comply with procedures for cognitive and other testing in the opinion of the investigator
  • Patient has a reliable caregiver who is willing to report on the subject's status throughout the study
  • Patients currently receiving therapy for DLB are eligible for enrollment

Exclusion Criteria:

  • Atypical clinical features or clinical course that would lead the investigator to conclude primary symptoms are more likely explained by an alternate dementia diagnosis.
  • Any clinically relevant concomitant disease that, in the opinion of the investigator, makes the patient unsuitable for inclusion in the study.
