• Status: Terminated
• Trial end date: 2014-08-01
• Target enrollment: 0
• Participant gender: All

Summary

The goal of this clinical research study is to compare how the drug Sprycel (dasatinib) can help to control the tumor in Patients With Acral Lentiginous, Mucosal, or Chronic Sun-damaged Melanoma. The safety of this drug will also be studied.

Objectives:

Primary Objectives:

1. To compare the biological response of tumors With and Without Resectable Tumors from patients with acral, or mucosal melanomas after treatment with dasatinib.

Secondary Objectives:

1. To assess the safety and tolerability of dasatinib in this patient population

Completely Resectable Acral, Chronic Sun-damaged (CSD), and Mucosal Melanoma:

2. To assess the median time to recurrence and overall survival of patients with completely resectable acral, CSD, and mucosal melanoma treated with dasatinib

3. To assess whether FDG-avidity and KIT phosphorylation responses after treatment with dasatinib predicts prolonged time to recurrence and/or overall survival in patients with completely resectable acral, CSD, and mucosal melanomas

Not Completely Resectable Acral, CSD, and Mucosal Melanoma:

4. To assess the response rate, progression free survival, and overall survival of patients with acral, CSD, and mucosal melanoma treated with dasatinib

5. To assess whether FDG-avidity and KIT phosphorylation responses after treatment with dasatinib predicts response rate, progression free survival, and/or overall survival in patients with acral, CSD, and mucosal melanomas

• Phase: Phase 2

Criteria

Inclusion Criteria:

1. Patients must have primary, recurrent or metastatic melanoma with one of the following pathology or characteristics: i) acral lentiginous melanoma ii) mucosal melanoma iii) any known KIT mutation.

2. (Continued 1) If 20 patients without tumors harboring exon 11 or 13 KIT mutation are enrolled and treated before the completion of the patient accrual of 30, only those with tumors harboring exon 11 or 13 KIT mutation will be enrolled. Likewise, if 10 patients with tumors harboring exon 11 or 13 KIT mutation are enrolled and treated before the completion of the patient accrual of 30, only those without tumors harboring exon 11 or 13 KIT mutation will then be enrolled.

3. Patients must have measurable disease by 18-Fluoro-deoxyglucose positron emission tomography (FDG-PET) (with or without computed tomography (CT)) defined as having a maximum standardized uptake value (SUVmax) of 3 and SUVmax ofat least 2 fold greater than background.

4. Patients scheduled for FDG-PET should have uptake of the tracer in at least one lesion (tumor-to-muscle ratio >2) in the baseline PET/CT scan in order to be eligible for the follow-up FDG PET scans.

5. Patient must have surgically resectable melanoma lesion(s) or biopsiable lesion(s) which are amenable to 2 separate biopsy procedures by a core needle or excision.

6. Age >/= 18 years.

7. Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.

8. Adequate Organ Function: a. Total bilirubin < 2.0 times the institutional Upper Limit of Normal (ULN), b.Hepatic enzymes (aspartate transaminase, alanine transaminase (AST, ALT) )institutional ULN, d.Neutrophil count >/= 1500; Platelets >/= 75,000;

9. Ability to take oral medication (dasatinib must be swallowed whole)

10. Concomitant Medications: a. Patient agrees to discontinue St. Johns Wort while receiving dasatinib therapy (discontinue St. Johns Wort at least 5 days before starting dasatinib), b.Patient agrees that IV bisphosphonates will be withheld for the first 8 weeks of dasatinib therapy due to risk of hypocalcemia.

11. Women of childbearing potential (WOCBP) must have: a) A negative serum or urine pregnancy test (sensitivity 25 IU human chorionic gonadotropin (HCG/L) within 72 hours prior to the start of study drug administration b) Persons of reproductive potential must agree to use and utilize an adequate method of contraception throughout treatment and for at least 4 weeks after study drug is stopped. Prior to study enrollment, women of childbearing potential must be advised of the importance of avoiding pregnancy during trial participation and the potential risk factors for an unintentional pregnancy.

12. Signed written informed consent including a Health Insurance Portability and Accountability Act (HIPAA) form according to institutional guidelines

Exclusion Criteria:

1. No other malignancy which required radiotherapy or systemic treatment within the past 5 years.

2. Concurrent medical condition which may increase the risk of toxicity, including: a. Pleural or pericardial effusion of any grade.

3. Cardiac Symptoms; any of the following should be considered for exclusion: a. Uncontrolled angina, congestive heart failure or MI within (6 months), b. Diagnosed congenital long QT syndrome, c. Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de pointes), d. Prolonged corrected QT interval (QTc) interval on pre-entry electrocardiogram (> 480 msec) [or > 500 msec for patients with a bundle branch block]), e. Subjects with hypokalemia or hypomagnesemia if it cannot be corrected prior to dasatinib administration.

4. History of significant bleeding disorder unrelated to cancer, including: a. Diagnosed congenital bleeding disorders (e.g., von Willebrand's disease), b. Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies), c. Ongoing or recent (

5. Concomitant Medications, any of the following should be considered for exclusion: a. Category I drugs that are generally accepted to have a risk of causing Torsades de Pointes including: (Patients must discontinue drug 7 days prior to starting dasatinib), I. quinidine, procainamide, disopyramide, II. amiodarone, sotalol, ibutilide, dofetilide, III. erythromycin, clarithromycin, IV. chlorpromazine, haloperidol, mesoridazine, thioridazine, pimozide V. cisapride, bepridil, droperidol, methadone, arsenic, chloroquine, domperidone, halofantrine, levomethadyl, pentamidine, sparfloxacin, lidoflazine.

9. HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with dasatinib. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.

10. Patients with melanoma harboring BRAF mutation. If BRAF mutation is not known at the time of screening, patients will still be eligible
