Trial summary

Activating mutations of the kinases CKIT or PDGFRA can be detected in 90% of cases by DNA sequence analysis of a pathological specimen. These mutated genomic DNA fragments are highly specific for the tumor and are released by the tumor into the circulation. Read more about this study

About this study

Official title: Prospective, Explorative Trial for the Detection of Circulating Cell-free Tumor DNA in the Plasma of Patients With Gastrointestinal Stromal Tumors (GIST)Harboring Activating Mutations of CKIT or PDGFRA Pre/Post Surgery or Pre/Under Treatment With a Tyrosine Kinase Inhibitor or Progressive Disease Irrespective of Current or Planned Treatment. An Open-label, Non-randomized, Multicenter Phase IIIb Clinical Trial

Activating mutations of the kinases CKIT or PDGFRA can be detected in 90% of cases by DNA sequence analysis of a pathological specimen. These mutated genomic DNA fragments are highly specific for the tumor and are released by the tumor into the circulation. Allele-specific PCR can be used to specifically amplify and quantify mutated CKIT and PDGFR DNA fragments.

The current trial aims to evaluate whether tumor DNA carrying mutations for CKIT and PDGFRA can be detected and quantified in the plasma of patients with active GIST, and whether detection can be correlated with the clinical course of disease either under therapy or in progressive disease irrespective of current therapy.

Being tested
Blood will be withdrawn at baseline and in intervals of 3 months for a total period of 2 years
Keywords

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Blood will be withdrawn at baseline and in intervals of 3 months for a total period of 2 years in people with Gastrointestinal Stromal Tumors, run by Technical University of Munich at 1 site in Germany.

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 8 inclusion and 12 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 17 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Percentage of patients with histologically proven GIST, measurable lesion in imaging and activating CKIT and PDGFRA mutation, where detection of tumor specific DNA encoding for mutated CKIT or PDGFA is possible in the plasma at least at one timepoint. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 17 Mar 2016.
