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

14 years to 61 years (Adult, Older Adult)

Accepts Healthy Volunteers

Evidence of disease that may influence the outcome of the study within 4 weeks before dosing; example, psychiatric disorders and disorders of the gastrointestinal tract, liver, kidney, respiratory system, endocrine system, hematological system, neurological system, or cardiovascular system, or subjects who have a congenital abnormality in metabolism
  3. Exposure within the last 14 days before dosing to an individual with confirmed or probable corona virus disease-2019 (COVID-19) or symptoms within the last 14 days that are on the most recent Centers for Disease Control and Prevention list of COVID symptoms or any other reason to consider the participant at potential risk for COVID-19 infection
  4. Participants who had received COVID vaccine but are not 14 days post full vaccination before dosing
  5. Currently enrolled in another clinical study or used any investigational drug or device within 28 days or 5 half-lives of the other investigational drug, whichever is longer, preceding informed consent
  6. Prior exposure to lecanemab
  7. Hypersensitivity to lecanemab or any of the excipients, or to any monoclonal antibody treatment

NOTE-Other protocol defined Inclusion/Exclusion criteria may apply.

What is the study measuring?

Primary Outcome Measures
