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

This is an open-label Phase II Study to determine the efficacy of Gleevec® in neurofibromatosis (NF1) patients with plexiform neurofibromas with the secondary goals of determining the toxicity, and tumor markers in this genetically defined population. The rationale for this study arises from the response of human and murine NF1 cells to Gleevec® in vitro and the response of a single NF1 patient treated with Gleevec® for airway compression by a plexiform neurofibroma with a dramatic response not previously seen in NF1 therapy. The plan of therapy will include oral dosing of Gleevec® at 440 mg/m^2/day (max 800 mg/day) for pediatric subjects and 800 mg/day for adult patients. (with 25% dose reduction for significant toxicity). Treatment will continue for 6 months with an option to continue as long as the patient remains on study provided the patient shows benefit from treatments with Gleevec® and there are no safety concerns.

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

3 years to 65 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Patients 3-65 years of age.
  2. Diagnosis of neurofibromatosis (NF1), as outpatients.
  3. Presence of clinically significant plexiform neurofibromas (biopsy proven if possible with tissue blocks available); that is tumors that are potentially life threatening or are impinging on vital structures or significantly impair the quality of life from pain or other symptoms.
  4. Patients must have measurable disease by magnetic resonance imaging (MRI). Patients must have a Karnofsky or Lansky Performance score of > 80% and a life expectancy of > 2 months.

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

    total bilirubin < 1.5 x ULN, SGOT and SGPT < 2.5 x UNL, creatinine < 1.5 x ULN, ANC > 1.5 x 109/L, platelets > 100 x 109/L.

  6. 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.
  7. Written, voluntary informed consent.

Exclusion criteria:

  1. Patient has received any other investigational agents within 28 days of first day of study drug dosing, unless the disease is rapidly progressing.
  2. Patient is < 5 years free of another primary malignancy except: if the other primary malignancy is not currently clinically significant nor requiring active intervention, or if other primary malignancy is a basal cell skin cancer or a cervical carcinoma in situ. Existence of any other malignant disease is not allowed.
  3. Patient 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)
  4. Female patients who are pregnant or breast-feeding.
  5. Patient has a severe and/or uncontrolled medical disease (i.e., uncontrolled diabetes, chronic renal disease, or active uncontrolled infection).
  6. Patient has a known brain metastasis. Non-specific CNS changes on MRI/CT characteristic of NF1 are allowed, but not known CNS malignancies.
  7. Patient has known chronic liver disease (i.e., chronic active hepatitis, and cirrhosis).
  8. Patient has a known diagnosis of human immunodeficiency virus (HIV) infection.
  9. Patient received chemotherapy within 4 weeks (6 weeks for nitrosourea or mitomycin-C) prior to study entry, unless the disease is rapidly progressing.
  10. Patient previously received radiotherapy to greater than 25 % of the bone marrow
  11. Patient had a major surgery within 2 weeks prior to study entry.
  12. Patient with any significant history of non-compliance to medical regimens or with inability to grant reliable informed consent.

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
Percent Change From Baseline in Tumor Volume at 6 Months
Time Frame: baseline to 6 months
Volumetric measures were performed using MRI scan analysis. Response criteria include greater than 20 percent decrease in tumor volume as responsive. Greater than 20 percent increase in tumor volume as tumor progression. Less then 20 percent increase or decrease in tumor volume is stable disease
baseline to 6 months

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
Serum Bioactivity
Time Frame: 7 days and 1 month
The investigators will quantitate the biologic activity of patient serum on fibroblast proliferation, migration, and collagen synthesis pre and post-Gleevec (7 days and 1 month)
7 days and 1 month
