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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

No

Genders Eligible for Study

All

Description

Inclusion criteria:

  1. Patients ≥ or equal to 18 years of age.
  2. Suspected or documented diagnosis of dermatofibrosarcoma protuberans (DFSP). Patients with suspected diagnosis of DSFP must have DFSP confirmed by pathology at the local institution prior to dispensing and the start of imatinib.
  3. Patient is medically able to undergo surgical resection of the DFSP and resection of the DFSP is recommended for clinical management of the disease.
  4. Patient has at least one site of measurable (macroscopic) disease.
  5. Performance status 0, 1 or 2 Eastern Cooperative Oncology Group (ECOG) (see Section 7.1).

  6. Adequate end organ function, defined as the following:

    total bilirubin < 1.5 x institutional upper limit of normal (ULN), SGOT and SGPT < 2.5 x UNL, creatinine < 1.5 x ULN, absolute neutrophil count > 1.5 x 109/L, platelets > 100 x 109/L.

  7. Female patients of childbearing potential must have negative pregnancy test within 7 days before initiation of study drug dosing. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential. Male and female patients of reproductive potential must agree to employ an effective barrier method of birth control throughout the study and for up to 3 months following discontinuation of study drug.
  8. Written, voluntary informed consent.

Exclusion criteria:

  1. Patients who will receive radiation therapy to the site of DFSP prior to resection.
  2. Patients with Grade III/IV cardiac problems as defined by the New York Heart Association Criteria (i.e., congestive heart failure, myocardial infarction within 6 months of study).
  3. Female patients who are pregnant or breast-feeding.
  4. Patients who have a severe and/or uncontrolled medical disease (i.e., uncontrolled diabetes, chronic renal disease, or active uncontrolled infection) that may worsen because of imatinib.
  5. Patients who have known chronic liver disease (i.e., chronic active hepatitis, and cirrhosis).
  6. Patients who have a known diagnosis of human immunodeficiency virus (HIV) infection.
  7. Patients who have received chemotherapy within 4 weeks prior to study entry.
  8. Patients who have had a major surgery within 2 weeks prior to study entry. Incisional biopsy or partial excision of dermatofibrosarcoma protuberans to establish the diagnosis and/or to collect pretreatment tumor tissue does not qualify as major surgery.

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
To Collect Matched Tumor Tissue of Trial Participants With Dermatofibrosarcoma Protuberans Before and After Treatment With Imatinib for Future Use in cDNA Microarray and Tissue Array Studies.
Time Frame: Prior to and after 2-weeks of imatinib therapy
To obtain matched tumor tissue samples of trial participants dermatofibrosarcoma protuberans (DFSP)for the purpose of determining whether imatinib mesylate affects autocrine/paracrine stimulated signal transduction through the platelet-derived growth factor receptor pathway in DFSP by comparing the level of phosphorylated platelet-derived growth factor receptor beta (PDGFRB) in DFSP after up to 2 weeks of treatment with imatinib to the level of phosphorylated PDGFRB pre-treatment.
Prior to and after 2-weeks of imatinib therapy

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
