  • Publication number: 20110111436
    Abstract: Sensitivity of a patient's cancer to treatment with 10-propargyl-10-deazaaminopterin is assessed and patients are selected for treatment of cancer with 10-propargyl-10-deazaaminopterin, by determining the amount of a selected polypeptide expressed by the cancer and comparing the amount with the amount of the selected polypeptide expressed by a reference cancer. The polypeptide includes a member of a folate pathway polypeptide within a cell and may include at least one of reduced folate carrier-1 enzyme (RFC-1), dihydrofolate reductase (DHFR), folylpoly-gamma-glutamate synthetase (FPGS), thymidylate synthase (TS), ?-glutamyl hydrolase (GGH), and glycinamide ribonucleotide formyltransferase (GARFT).

  • Patent number: 7939530
    Abstract: Lymphoma is treated using therapeutic combinations of PDX and gemcitabine by administering to a patient suffering from lymphoma a therapeutically effective amount of PDX in combination with a therapeutically effective amount of gemcitabine. The two agents can be administered together or in either order, although administration of PDX followed by gemcitabine is preferred. As in the case of MTX and Ara-C, synergism is observed, but the extent of the synergism is greater. Further, test results indicate that mechanism of action for combinations of PDX and Gem is different than for MTX and Ara-C, with more emphasis on induction of apoptosis.

  • Publication number: 20100168118
    Abstract: The present invention relates to a method for assessing the sensitivity of a patient's cancer to treatment with 10-propargyl-10-deazaminopterin and a method for selecting a patient for treatment of cancer with 10-propargyl-10-deazaminopterin, by determining the amount of a selected polypeptide expressed by the cancer and comparing the amount with the amount of the selected polypeptide expressed by a reference cancer, wherein the polypeptide includes a member of folate pathways within cells and may include at least one of reduced folate carrier-1 enzyme (RFC-1), dihydrofolate reductase (DHFR), folylpoly-gamma-glutamate synthetase (FPGS), thymidylate synthase (TS), ?-glutamyl hydrolase (GGH), and glycinamide ribonucleotide formyltransferase (GARFT). The present invention also relates to the use of 10-propargyl-10-deazaminopterin in the treatment of multiple myeloma.

  • Publication number: 20050267117
    Abstract: T cell lymphoma is treated by administering to a patient suffering from T cell lymphoma a therapeutically effective amount of 10-propargyl-10-deazaaminopterin. Remission is observed in human patients, even with drug resistant T cell lymphoma at weekly dosages levels as low as 30 mg/m2. In general, the 10-propargyl-10-deazaaminopterin is administered in an amount of from 30 to 275 mg/m2 per dose.
