Non Hodgkin Lymphoma Clinical Trial
Dasatinib in Relapsed or Refractory Non-Hodgkin’s Lymphoma
To determine the maximum tolerated dose (MTD) of Dasatinib in relapsed or refractory non-hodgkin's lymphoma (NHL) patients and to determine the safety of Dasatinib in NHL.
To assess the complete and overall response rates for all Phase I and Phase II patients and to determine overall survival and event free survival for all Phase I and Phase II patients.
To assay the levels of kinase activity in NHL specimens and correlate this activity to patient outcomes.
To determine the Maximum Tolerated Dose (MTD) of Dasatinib in relapsed or refractory Non-Hodgkin's lymphoma (NHL) patients and to determine the safety of Dasatinib in NHL
To assess the complete and overall response rates for all Phase I and Phase II patients and to assay the levels of kinase activity in NHL specimens and correlate this activity to patient outcomes.
To determine overall survival and event free survival for all Phase I and Phase II patients.
This study has two phases of treatment, Phase I and Phase II. The Phase I portion of the trial will consist of a dose escalation plan with 3-6 patients being enrolled into each dose cohort. The doses of Dasatinib used in Phase I are 100 mg, 150 mg, and 200 mg. The dose that is found to be tolerated the best and also has the best treatment results will be used for Phase II. An additional 29 patients will be enrolled into Phase II.
All patients will receive Dasatinib in this study. Dasatinib will be administered orally (by mouth) once daily for 28 day cycles. A cycle will be considered 28 days. Dosing will be continuous with no interruptions, unless instructed to interrupt treatment by the treating physician.
The patient will be restaged after every 2 cycles of therapy, every even cycle. Therapy may continue as long as there are no clinical signs of NHL progressing and the patient is tolerating the treatment with no side effects related to the therapy. If the patient is removed from study for any reason, he/she will be followed for survival until death.
Histologically confirmed diagnosis of non-hodgkin's lymphoma that is recurrent or refractory after at least one prior therapy and for which no other potentially curative therapy is available.
Subject, age > or = 19 years
Performance status (ECOG) 0-2
Patients must have relapsed or refractory disease after at least one prior systemic therapy, with at least a 3 week interval from the completion of the most recent chemotherapy or radiotherapy regimen. Recover to ≤ grade 1 from all toxicities related to the prior treatments is required.
Patients must be ineligible or relapsed after an autologous or allogeneic stem cell transplant if clinically appropriate.
Adequate Laboratory Parameters:
ANC ≥ 1000/μL
Platelet count ≥ 50,000/μL
Total bilirubin < 2.0 times the institutional upper limit of normal (ULN)
Hepatic enzymes (AST, ALT ) ≤ 2.5 times the institutional ULN
Serum creatinine < 2.0 times the institutional ULN
PTT within institutional normal limits
Ability to take oral medication (dasatinib must be swallowed whole)
Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (sensitivity < or = 25IU HCG/L) within 72 hours prior to the start of study drug administration
Persons of reproductive potential must agree to use an adequate method of contraception throughout treatment and for at least 6 months after study drug is stopped
Signed written informed consent including HIPAA according to institutional guidelines
No malignancy [other than the one treated in this study] which required systemic treatment within the past 3 years.
Concurrent medical condition which may increase the risk of toxicity, including:
Clinically significant pleural or pericardial effusion
Clinically-significant coagulation or platelet function disorder (e.g. known von Willebrand's disease)
Cardiac Symptoms, consider the following:
Uncontrolled angina, congestive heart failure or MI within (6 months)
Diagnosed congenital long QT syndrome
Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de pointes)
Prolonged QTc interval on pre-entry electrocardiogram (> 450 msec)
Subjects with hypokalemia or hypomagnesemia if it cannot be corrected
History of significant bleeding disorder unrelated to cancer, including:
Diagnosed congenital bleeding disorders (e.g., von Willebrand's disease)
Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies)
Ongoing or recent (< or = 3 months) significant gastrointestinal bleeding
Concomitant Medications, consider the following prohibitions:
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.) quinidine, procainamide, disopyramide, amiodarone, sotalol, ibutilide, dofetilide,erythromycin, clarithromycin, chlorpromazine, haloperidol, mesoridazine, thioridazine, pimozide, cisapride, bepridil, droperidol, methadone, arsenic, chloroquine, domperidone, halofantrine, levomethadyl, pentamidine, sparfloxacin, lidoflazine.
The concomitant use of H2 blockers or proton pump inhibitors with dasatinib is not recommended. The use of antacids should be considered in place of H2 blockers or proton pump inhibitors in patients receiving dasatinib therapy.
Patient agrees to discontinue St. Johns Wort while receiving dasatinib therapy
Patient agrees that IV bisphosphonates will be withheld for the first 8 weeks of dasatinib therapy due to risk of hypocalcemia.
Patient may not be receiving any prohibited CYP3A4 inhibitors
Are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for at least 4 weeks 6 months after cessation of study drug
Have a positive pregnancy test at baseline
Are pregnant or breastfeeding
Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious) illness
