Multiple Ascending Dose Study of TC-5619 in Healthy Elderly Subjects and Subjects With Alzheimer's Disease

September 3, 2013 updated by: Targacept Inc.

Two-Part, Sequential Multiple Ascending Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of TC-5619-238 in Elderly Subjects With and Without Alzheimer's Disease

This is a Phase 1 study to examine the safety, tolerability and pharmacokinetics of TC-5619 in elderly subjects with and without Alzheimer's disease. Group 1 includes elderly subjects with Alzheimer's disease to receive TC-5619 or placebo for 28 days to evaluate safety and tolerability. Group 2 includes healthy elderly subjects in a dose escalation design to receive TC-5619 or placebo for 10 days to evaluate safety, tolerability and pharmacokinetics.

Study Overview

Status

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

55 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

  • Subjects must be in reasonably good health, based on medical history, physical examination, vital signs, and ECG.

Group 1 Only:

  • Subjects a Mini Mental State Examination score between 12-22, inclusive.
  • Diagnosis of probable Alzheimer's Disease according to National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria
