About this study

Official title: Phase II Study of Crenolanib (CP-868,596), a Selective and Potent Inhibitor of PDGFR, for the Treatment of Patients With Advanced Gastrointestinal Stromal Tumors With the D842-related Mutations and Deletions, Including the D842V Mutation, in the PDGFRA Gene

This Phase II study is designed to evaluate the antitumor efficacy and pharmacokinetics of crenolanib (CP-868,596) in patients with D842-related mutant metastatic GIST.

Read the detailed description

Crenolanib (CP-868,596) is an orally bioavailable, selective inhibitor of PDGFR receptor tyrosine kinase with IC50s of 0.4 ng/mL and 0.8 ng/mL for PDGFRα and PDGFRβ, respectively.

In preclinical models of cell lines with the D842V mutation in the PDGFRA gene, crenolanib (CP-868,596) blocked phosphorylation of PDGFRα at nanomolar concentrations, suggesting that it may provide a clinical benefit to patients with D842V mutant GIST.

In addition, crenolanib was also active in inhibiting phosphorylation of cell lines with two point mutations (double mutants) PDGFRA V561D + D842V and PDGFRA T674I + D842V.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary end-point is overall response rate

    To determine the response rate of patients with advanced D842V mutant GIST, when treated with Crenolanib (CP-868,596). Response will primarily be determined by RECIST criteria

    Measured: 1.5 years

Secondary outcomes (3)
  1. Progression free survival rate

    To determine the progression free survival rate at 6 months in patients with advanced GIST with the D842V mutation in the PDGFRA gene, when treated with CP-868,596 (crenolanib).

    Measured: 6 months

  2. Obtain toxicity information

    To obtain additional toxicity information in patients with advanced GIST with the D842V mutation in the PDGFRA gene.

    Measured: 1 year

  3. PKPD analysis

    To obtain additional PK, pharmacodynamic and plasma inhibitory assay information in patients with advanced GIST with the D842V mutation in the PDGFRA gene.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Crenolanib besylate (CP-868,596-26), Dose: 140mg BID in people with D842-related Mutant GIST, run by Arog Pharmaceuticals, Inc. at 2 sites in United States.

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 10 inclusion and 10 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 28 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

The primary end-point is overall response rate (time frame: 1.5 years). 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 NCT01243346, 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 28 Jun 2018.
