March 11, 2024 updated by: Jiangsu Alphamab Biopharmaceuticals Co., Ltd

Phase II Study of Evaluating Efficacy, Safety and Tolerance of KN026 in HER2 Expressing Advanced Gastric/Gastroesophageal Junction Cancer

This is an open-label, phase 2 study of KN026 in subjects with HER2 expressing gastric/gastroesophageal junction cancer to evaluate efficacy and safety. The subjects will receive KN026 10 mg/kg QW or 20 mg/kg Q2W or 30mg/kg Q3W until progressive disease, unacceptable toxicity or death.

Study Overview

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

The study consists of two arms as HER2 overexpression arm and HER2 expression arm and both arms will receive KN026 treatment.

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

18 years to 75 years (Adult, Older Adult)
