A Study of EMB-02 in Participants With Advanced Solid Tumors

May 17, 2024 updated by: Shanghai EpimAb Biotherapeutics Co., Ltd.

A Phase I/II Trial of EMB-02, a Bi-specific Antibody Against PD-1 and LAG-3, in Patients With Advanced Solid Tumors

The primary purpose of this study is to identify the recommended Phase 2 dose(s) (RP2Ds) and schedule assessed to be safe for EMB-02 and to characterize the safety and tolerability of EMB-02 at the RP2Ds. Pharmacokinetics (PK), immunogenicity, and the anti-tumor activity of EMB-02 will also be assessed.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase I/II, multi-center, open label, multiple-dose, first in human study, designed to assess safety and tolerability, and to identify the maximum tolerated dose (MTD) and/or recommended Phase 2 dos(s)e (RP2D[s]) for EMB-02 in patients with advanced solid tumors. Pharmacokinetics, pharmacodynamics, immunogenicity, and response will also be assessed.

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.
