TrasGEX™: Phase 1 Study in Cancer Patients

May 4, 2021 updated by: Glycotope GmbH

A Phase I Dose-Escalation and Pharmacokinetic Study of TrasGEX™ in Patients With Locally Advanced or Metastatic HER-2-positive Cancer

This was a prospective, open label, multicenter study evaluating the safety, tolerability and pharmacokinetics of TrasGEX™ after intravenous administration in patients with HER-2 positive cancers. The effect of TrasGEX™ on the development of anti-drug antibodies and on tumour response was also evaluated.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Adult patients with advanced and/or metastatic HER2-positive cancer who were resistant to or for whom there was no standard anti-tumor therapy available at the time of enrollment and who had an estimated life expectancy of at least 3 months were eligible for participation in this study.

Patients were to receive the study drug until disease progression (clinical or radiologic), unacceptable toxicity, or any other reason leading to termination of study treatment.

Dose-escalation was performed in 3 to 6-patient cohorts.

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 and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

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
Measure Description
Time Frame
optimal dose and regimen of TrasGEX™
Time Frame: up to at least 8 weeks after the first TrasGEX™ administration
The primary objective of this first-in-man study is to determine the optimal dose and regimen of TrasGEX™ in patients with locally advanced or metastatic human epidermal growth factor receptor-2 (HER-2)-positive cancer. The recommended phase II dose needs to have an acceptable safety profile and provides evidence for efficacy based on clinical observations or the pharmacokinetic profile.
up to at least 8 weeks after the first TrasGEX™ administration

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
To determine preliminary evidence of activity
Time Frame: approx. every 8 weeks
CT or MRI imaging will be performed. Assessment of tumor response (SD, PR, CR. PD) will be performed following a modified version of the revised RECIST guidelines, version 1.1. Basically, patients will receive treatment with TrasGEX™ until progression of disease and/or unacceptable toxicities are observed.
approx. every 8 weeks
safety and tolerability of TrasGEX™
Time Frame: until 4 weeks after the last treatment with TrasGEX™
To assess the safety and tolerability of TrasGEX™ in patients with advanced and/or metastatic HER-2-positive cancer at various dose levels considering observed adverse events, laboratory values, vital signs, ECOG performance status and physical examination.
until 4 weeks after the last treatment with TrasGEX™
To assess the pharmacokinetic (PK) profile of TrasGEX™ (part I)
Time Frame: prior to 1st infusion until the end of 5th infusion
c(max): to determine the PK profile samples will be taken before the first infusion and up to 24 h after after infusion, followed by weekly samples for the first infusion and samples immediately before and after infusion for the following infusions
prior to 1st infusion until the end of 5th infusion
To assess the pharmacokinetic (PK) profile of TrasGEX™ (part II)
Time Frame: prior to 1st infusion until the end of 5th infusion
t(1/2): to determine the PK profile samples will be taken before the first infusion and up to 24 h after after infusion, followed by weekly samples for the first infusion and samples immediately before and after infusion for the following infusions
prior to 1st infusion until the end of 5th infusion
