A Drug Interaction Study of Lanabecestat (LY3314814) and Warfarin in Healthy Participants

October 18, 2019 updated by: AstraZeneca

Effect of LY3314814 on the Pharmacokinetics of Warfarin in Healthy Subjects

The purpose of this study is to look at how much warfarin gets into the blood stream and how long it takes the body to get rid of it when given both with and without lanabecestat. Another purpose is to evaluate the effectiveness of warfarin therapy to prevent blood clots when given with lanabecestat by measuring international normalized ratio (INR). INR measures the time it takes for blood to clot and compares it to an average. Information about any side effects that may occur will also be collected. The study will last about 5 weeks from the first dose to follow-up for each participant.

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.

What is the study measuring?
