Study Safety and Preliminary Efficacy of DCC-2036 in Patients With Leukemias (Ph+ CML With T315I Mutation)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00827138

Brief Summary:
Rationale: DCC-2036 is a potent broad spectrum inhibitor of BCR-ABL kinase. Inhibition of BCR-ABL has been validated for effective treatment of chronic myeloid leukemia (CML). The emergence of mutant forms of BCR-ABL which resist inhibition by imatinib, dasatinib, and nilotinib is associated with loss of efficacy in treatment of the disease. DCC-2036 is a potent inhibitor of resistant mutants of BCR-ABL including the T315I mutation, and would therefore be expected to effectively treat patients who fail to respond to other BCR-ABL inhibitors. DCC-2036 also inhibits FLT3-ITD, TIE2, KDR, LYN and TRKA kinases. Purpose: to assess the safety and tolerability in patients after continuous administration of DCC-2036 and to determine recommended doses for the conduct of a Phase 2 efficacy trial.

Condition or disease Intervention/treatment Phase
Chronic Myeloid Leukemia Drug: DCC-2036 Phase 1

Detailed Description:

This study will include patients with one of the following: (1) Philadelphia chromosome-positive (Ph+) Chronic myeloid leukemia (CML); (2) FLT3 (gene) internal tandem duplication positive acute myeloid leukemia [FLT3 (gene) ITD-AML]. The investigational drug DCC-2036 has shown in the laboratory to affect different kinds of proteins in CML or AML cancer cells, which may help to stop these cancer cells from growing. This is a Phase 1 study. This Phase 1 study will test the highest safe dose of the investigational drug, DCC-2036, how often the drug should be given, and how well Ph+ CML and AML patients will tolerate DCC-2036. Patients' study doctor will review their past medical history, surgery(s), known allergies, and past/current medications. In addition, blood tests and bone marrow biopsies will be taken to determine if persons are eligible to participate in this study.

During the first part of this study, patients will receive different amounts of DCC-2036 to determine the highest safe dose. Multiple dose levels of DCC-2036 will be tested and as long as no medically unacceptable side effects are noted, the dose will be increased for the next group of study patients. When the highest dose is reached, a larger number of patients will be enrolled to receive DCC-2036 at the highest (safe) dose level. Additional study patients will be enrolled in a group called an "Expansion Group" and receive the study drug at the highest well tolerated dose. Evaluation of the safety and efficacy (how well the study medication treats leukemia) will be studied in this trial. Disease assessment will be monitored as follows: (1) Blood samples will be collected for disease response and for mutational analysis if disease has gotten worse (progressed); (2) Bone marrow samples may be collected by having an area of the hip or chest bone numbed with an anesthetic and a small amount of bone marrow drawn through a needle; (3) For CML patients only, blood samples will be collected for BCR-ABL transcript levels. Patient safety is of primary importance in this Phase 1 study. Safety assessment will be monitored as follows: (1) Physical examinations will be performed regularly during your doctor's visits; (2) Routine blood tests will be performed on a regular basis to assess potential side effects that may be caused by study medication on different organs like (and not limited to) liver, kidney and bone marrow; (3) Based on reports of potential side effects to the heart that may be caused by study medication, patients will be required to have echocardiograms and blood draws to measure the level of serum N-terminal fragment pro B-type natriuretic peptide (NT-proBNP). An echocardiogram is a noninvasive test that uses sound waves to produce images of your heart. These images will tell the doctor how a patient's heart is beating and pumping. The NT-proBNP is a blood test that will help the patient's doctor evaluate how well the heart works. After initial testing is completed, patients will then be required to have these safety evaluations performed at intervals of 3-cycles (approximately every 3 months) for as long as they are taking the study medication. Patients who experience muscle weakness or peripheral neuropathy will be assessed by blood draws to measure creatine phosphokinase (CPK) levels. Measuring CPK levels may help the patient's doctor determine whether or not the symptoms they are experiencing are the result of muscle damage or due to other causes. The most common eye disorders include blurred vision, dry eyes, and visual impairment. Patients will be required to have complete eye (ophthalmologic) evaluations. After initial ophthalmologic exams, patients will be required to have an exam after the completion of every 3 cycles of study medication (approximately every 3 months) and at the time they stop taking study medication. Blood samples will be collected for pharmacokinetic analysis. Pharmacokinetics is the study of the bodily absorption, distribution, metabolism, and excretion of drugs. Blood samples will also be collected for pharmacodynamic analysis. Pharmacodynamic analysis measures biomarkers that are either proteins or genes (also called DNA) that are associated with a disease that may also be related to how you respond to a treatment or what type of side effects may happen. The investigational drug DCC-2036 has not been approved by the United States Food and Drug Administration (FDA). The FDA allows DCC-2036 to be used in research studies only. DCC-2036 will be given to patients only during this study and not after the study is over.
