The purpose of this study if to investigate the effect of lonafarnib (SCH66336) in combination with Gleevec in the treatment of CML.
Existing pre-clinical and clinical data suggest that SCH66336, a farnesyl transferase inhibitor,exhibits significant activity against CML cells, and in fact may have synergistic activity in combination with imatinib mesylate. Thus, the objectives to the study are (1) to determine the maximum tolerated dose (MTD) and dose limiting toxicities (DLT) of lonafarnib (SCH66336), a farnesyl transferase inhibitor, in combination with imatinib mesylate (Gleevec) in patients with chronic phase, accelerated phase, and blast crisis CML; (2) to assess the pharmacokinetics of the combination of lonafarnib and Gleevec in these patients; and (3) to assess in a preliminary way the biologic activity of the combination of lonafarnib and Gleevec in these patients.

RATIONALE: Imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for their growth. It is not yet known which dose of imatinib mesylate is more effect...
ZNF224 is a KRAB-zinc finger transcription factor that exerts a key tumor suppressive role in chronic myelogenous leukemia. In this study, we identify the receptor tyrosine kinase Axl as a novel targe...
Does switching to a second-generation tyrosine kinase inhibitor or increasing imatinib dose have long-term benefits in chronic myeloid leukemia patients with suboptimal responses under upfront standard-dose of imatinib?
The advent of tyrosine kinase inhibitors (TKI) has improved prognosis and outcome of patients with chronic myelogenous leukemia (CML) considerably. In comparison to imatinib, first line use of second ...
The use of generic drugs after patent expiration of their originators is a relative novelty in the treatment of chronic cancer patients in Western countries. In this observational study we analyzed a ...
T315I mutation is the most common BCR-ABL mutation and confers resistance to all the first and second generation BCR-ABL tyrosine kinases, including nilotinib and dasatinib. We report a high risk chro...
A tyrosine kinase inhibitor and ANTINEOPLASTIC AGENT that inhibits the BCR-ABL kinase created by chromosome rearrangements in CHRONIC MYELOID LEUKEMIA and ACUTE LYMPHOBLASTIC LEUKEMIA, as well as PDG-derived tyrosine kinases that are overexpressed in gastrointestinal stromal tumors.
An aberrant form of human CHROMOSOME 22 characterized by translocation of the distal end of chromosome 9 from 9q34, to the long arm of chromosome 22 at 22q11. It is present in the bone marrow cells of 80 to 90 per cent of patients with chronic myelocytic leukemia (LEUKEMIA, MYELOGENOUS, CHRONIC, BCR-ABL POSITIVE).
Clonal hematopoetic disorder caused by an acquired genetic defect in PLURIPOTENT STEM CELLS. It starts in MYELOID CELLS of the bone marrow, invades the blood and then other organs. The condition progresses from a stable, more indolent, chronic phase (LEUKEMIA, MYELOID, CHRONIC PHASE) lasting up to 7 years, to an advanced phase composed of an accelerated phase (LEUKEMIA, MYELOID, ACCELERATED PHASE) and BLAST CRISIS.
Retrovirus-associated DNA sequences (abl) originally isolated from the Abelson murine leukemia virus (Ab-MuLV). The proto-oncogene abl (c-abl) codes for a protein that is a member of the tyrosine kinase family. The human c-abl gene is located at 9q34.1 on the long arm of chromosome 9. It is activated by translocation to bcr on chromosome 22 in chronic myelogenous leukemia.
A pyrimidine and thiazole derived ANTINEOPLASTIC AGENT and PROTEIN KINASE INHIBITOR of BCR-ABL KINASE. It is used in the treatment of patients with CHRONIC MYELOID LEUKEMIA who are resistant or intolerant to IMATINIB.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
