Data taken from EUROCARE showed large variations in survival rates from several hematologic malignancies across European countries, with lower survival in Eastern Europe and higher survival in Northern and Central Europe.
STAT3 inhibition using a novel compound restored sensitivity to TKIs in CML cells that had shown resistance independent of BCR-ABL1 kinase activity.
Ponatinib showed significant antileukemic activity in patients with CML and ALL, according to a phase II study that included a wide range of disease stages and mutation status; patients in the trial had a relatively high rate of adverse thrombotic events, an issue which has led to recent regulatory controversy surrounding the drug.
A phase I study of dasatinib in children and adolescents with chronic myeloid leukemia (CML) and other malignancies determined dosing for further studies and suggested the drug is well tolerated and effective in these patients.
A majority of patients on imatinib for treatment of GIST or CML had low or absent levels of osteocalcin, a bone marker secreted by osteoblasts, and about 50% of patients had a decrease in bone mineral density, signaling that long-term treatment may affect bone health in these patients.
The US Food and Drug Administration has approved ponatinib (Iclusig) to treat adults with chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia.
Updated clinical data from the pivotal phase II global PACE trial of ponatinib confirm its impressive antileukemic activity in patients with chronic myeloid leukemia or Philadelphia-chromosome-positive acute lymphoblastic leukemia at all stages who are resistant or intolerant to dasatinib or nilotinib.
In his plenary address as outgoing president of ASCO, Dr. George Sledge proposed that we are on the brink of a new era in cancer therapy – an era of genome-based treatment. He stressed that this new “genomic era” holds great promise for patients, citing as evidence a recent paper in JAMA that described a case in which the results of deep sequencing of a patient’s leukemic cells led to successful individualized therapy.
For the first time, a series of metastatic melanoma (MM) patients have been genetically tested for the constitutively activating BRAF mutation and assessed for its prognostic significance as is routinely done for breast cancer (HER2) and chronic myeloid leukemia (ABL).
Eighteen-month follow up supports lower-dose nilotinib as the new standard of care for newly diagnosed chronic myeloid leukemia. The ENESTnd trial (Evaluating Nilotinib Efficacy and Safety in Clinical Trials of Newly Diagnosed Ph+CML Patients) enrolled 846 patients at 217 sites in 35 countries. Timothy P. Hughes, MD, MBBS, will present an update to the ENESTnd trial at ASH 2010.
