Efficacy and Safety Study of Multiple Doses of IMAB362 in Patients With Advanced Gastroesophageal Cancer

June 11, 2025 updated by: Ganymed Pharmaceuticals GmbH

International, Multicenter, Open-label, Phase II Study to Investigate the Efficacy and Safety of Multiple Doses of IMAB362 in Patients With Advanced Adenocarcinoma of the Stomach or the Lower Esophagus

IMAB362 is a monoclonal antibody specific for gastric or lower esophageal adenocarcinoma. Preclinically IMAB362 was shown to inhibit tumor growth and to kill cancer cells by indirect (complement-dependent cytotoxicity, antibody-dependent cellular cytotoxicity) and direct mechanisms (antiproliferative and proapoptotic effects). The aim of this phase II study is to establish efficacy and safety of multiple doses of IMAB362 as monotherapy in patients suffering from metastatic, refractory or recurrent adenocarcinoma of the stomach or the lower esophagus.

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.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • Metastatic, refractory or recurrent disease of advanced adenocarcinoma of the stomach or the lower esophagus proven by histology
  • CLDN18.2 expression of the biopsy material from the cancer confirmed by immunohistochemistry
  • At least 1 measurable site of disease according to RECIST criteria

Exclusion Criteria:

  • Less than 3 weeks since prior chemo-or radiation therapy
  • Other concurrent anticancer therapies
  • Concurrent anticoagulation with vitamin K antagonists
  • Therapeutic doses of Heparin (prophylactic doses accepted)
  • Uncontrolled or severe illness

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Rate of remission (CR, PR) according to RECIST Criteria
Time Frame: All patients will be evaluated in 8-12 weeks intervals until 6 months after last infusion
All patients will be evaluated in 8-12 weeks intervals until 6 months after last infusion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants with adverse events as a measure of safety and tolerability
