Brief Summary:
This study seeks to confirm a demonstrated treatment effect of intepirdine (RVT-101) as an adjunctive therapy to donepezil for the treatment of subjects with Alzheimer's disease.

Condition or disease Intervention/treatment Phase
Alzheimer's Disease Drug: RVT-101 Drug: Placebo Phase 3

Detailed Description:
This Phase 3 study seeks to confirm a demonstrated treatment effect of intepirdine (RVT-101) on both cognition and activities of daily living when added to stable donepezil treatment in subjects with mild-to-moderate Alzheimer's disease after 24 weeks of double-blind treatment. This study will also provide further information on the safety and tolerability of the 35-mg dose of intepirdine (RVT-101) when used in combination with donepezil compared to donepezil alone. This study is being conducted under the agreement of a Special Protocol Assessment by FDA. Subjects completing this study will be eligible to enroll in a 12 month open-label study of RVT-101 (RVT-101-3002) in which concomitant medications for the treatment of Alzheimer's disease including memantine will be allowed.

Ages Eligible for Study:   50 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female subject with AD
  • Ongoing donepezil therapy for AD
  • An MMSE score 12 to 24 inclusive at Screening; MMSE score 10-26 inclusive at Baseline
  • Hachinski Ischaemia score less than or equal to 4 at Screening.
  • If female, subject must be: a. of non-childbearing potential or surgically sterile; or, b. willing to use an adequate methods of birth control. Male subjects who are sexually active will also be required to use an adequate form of birth control.
  • Subject has the ability to comply with procedures for cognitive and other testing in the opinion of the investigator.
  • Subject has a reliable caregiver who is willing to report on subject's status throughout the study.

Exclusion Criteria:

Other Causes for Dementia

  • Diagnosis of vascular dementia
  • Atypical clinical features or clinical course of dementia that would lead the investigator to conclude symptoms are more likely due to an alternate dementia diagnosis including, but not limited to, frontotemporal dementia, Lewy body dementia, or others.

Confounding Medical Conditions

  • History of significant psychiatric illness such as schizophrenia or bipolar affective disorder or any other significant psychiatric illness that in the opinion of the investigator would interfere with participation in the study;
  • Any clinically relevant concomitant disease, which, in the opinion of the investigator, makes the subject unsuitable for inclusion in the study.
