About this study

Official title: Phase I Dose Escalation Study Evaluating the Safety and Tolerability of PankoMab-GEX™ in Patients With Advanced, TA-MUC1 Positive Solid Malignancies Who Are Not Longer Eligible for Standard Therapy

Prospective, open label, dose escalating, multicenter, phase I study measuring the safety, tolerability, and pharmacokinetics of PankoMab-GEX™ after intravenous administration in patients with locally advanced or metastatic solid cancers refractory to standard treatment. The effect of PankoMab-GEX™ on the development of antibodies and tumor response was also evaluated.

Read the detailed description

Male or female patients of age 18 years or older with a histologically-confirmed, tumor-associated mucin 1 (TA-MUC1) positive, measurable or non-measurable solid tumor who had failed standard therapy and for whom no standard therapy was available.

Open-label, non-randomized, inter-patient dose escalation, multi-center study in a 3 + 3 design.

Patients received PankoMab-GEX™ treatment until disease progression or until the treatment was no longer tolerated.

  5. Eastern Cooperative Oncology Group (ECOG) Performance Status

    The ECOG Scale of Performance Status describes a patient's level of functioning in terms of their ability to care for themself, daily activity, and physical ability (walking, working, etc.). The scale comprises six grades:

    0 Fully active, able to carry on all pre-disease performance without restriction

    1. Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, e.g., light house work, office work
    2. Ambulatory and capable of all selfcare but unable to carry out any work activities; up and about more than 50% of waking hours
    3. Capable of only limited selfcare; confined to bed or chair more than 50% of waking hours
    4. Completely disabled; cannot carry on any selfcare; totally confined to bed or chair
    5. Dead

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PankoMab-GEX™ in people with Solid Tumors, run by Glycotope GmbH at 4 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 May 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Italy, Germany, Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Treatment-Emergent Adverse Events assessed with the National Cancer Institute Common Terminology Criteria for Adverse Events [NCI CTCAE], Version 3.0 (time frame: Until 28±2 days following the last infusion). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01222624, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 May 2021.
