December 4, 2023 updated by: Mabwell (Shanghai) Bioscience Co., Ltd.

A Phase I Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics Characteristics and Immunogenicity of a Single Dose of 9MW1911 Injection in Healthy Subjects

This is a Phase 1, randomized, placebo-controlled study, enrolling approximately 38 healthy adult subjects (18-65 yrs). The purpose of this study is to evaluate the safety, tolerability and PK of single ascending dose of 9MW1911 administered intravenously (IV) in healthy adult volunteers. All subjects will be followed up for safety from the time of Informed Consent through 113 days post dose.

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.
