Filter by:This is a Phase I continuous infusion study designed to explore if constant concentration over time adds to the effectiveness of terameprocol without increasing toxicity. It will also explore weekly dosing as an option. Tumor response assessments will be performed following every two (2) cycles of therapy. All subjects will undergo a follow-up visit 30 days following their last dose of terameprocol. Circulating tumor cells (CTC) will be quantified pre dosing and on day 15 after first dose of each cycle. Needle biopsy specimens will be taken prior to therapy and one week after first dose, if possible, to assess for tumor markers (cdc-2 and survivin). Tumor markers, for example prostate specific antigen (PSA) will also be measured on day 15 of each cycle (if elevated on study entry). Pharmacokinetic parameters will be derived from analysis of blood samples collected during the first 24 hour infusion.
The purpose of this study is to find the highest dose of the drugs gemcitabine and dasatinib that can be given for the treatment of pancreatic cancer. Gemcitabine (also called Gemzar™)is a drug that is given intravenously. Dasatinib (also called Sprycel™) is a tablet and will be taken by mouth. Gemcitabine is approved by the Food and Drug Administration (FDA) for the treatment of advanced breast, lung and pancreatic cancer. Dasatinib is approved by the FDA for the treatment of chronic myeloid leukemia (CML), acute lymphoblastic leukemia or for patients that are resistant to imatinib mesylate (Gleevec™ ). This study will try to find the highest doses of these drugs that can be tolerated when taken in combination. The study will also look at how the drugs work in the body, and will see if there is any effect on pancreatic cancer.
Chemotherapy resistance, either innate or acquired requires for its development, expression changes on a large number of genes therefore, it has been hypothesized that epigenetic-mediated changes could be the responsible driving force for chemotherapy resistance. Aberrant DNA methylation and histone deacetylation are the main epigenetic alterations hence, their reversal by inhibitors of DNA methylation and histone deacetylases (HDACs) may overcome resistance in refractory solid tumors. Patients will be treated with hydralazine and magnesium valproate starting from day -7 until chemotherapy ends which consists on the same pre-study protocol regimen on which patients progressed. Response and toxicity were evaluated. Global DNA methylation and HDAC activity were evaluated in the peripheral blood cells, as well as the plasma levels of valproic acid and hydralazine.
