Single Dose Study of Tulisokibart (MK-7240) in Healthy Chinese Participants (MK-7240-002)

February 11, 2025 updated by: Merck Sharp & Dohme LLC

A Phase 1, Double-Blind, Placebo-Controlled, Single-Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of MK-7240 in Healthy Chinese Participants.

The goal of this study is to learn about the safety of tulisokibart in healthy participants and what happens to tulisokibart over time when participants receive treatment intravenously versus subcutaneously.

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.

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.
