  • Patent number: 8299078
    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.

  • Patent number: 8263354
    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: 6323205
    Abstract: Preliminary clinical studies in humans have now been done which show both the efficacy of 10-propargyl-10dAM and a preferred dosage schedule for such treatments. In addition, it has now been determined that combinations of 10-propargyl-10-deazaaminopterin (preferably highly purified forms, substantially free of 10-deazaaminopterin) with taxols exhibit synergistic effectiveness in the treatment of tumors. 10-propargyl-10-deazaaminopterin and a taxol in therapeutically effective amounts can be administered concurrently, one right after the other, or with a period of time in between.

  • Patent number: 6028071
    Abstract: Highly purified 10-propargyl-10-deazaaminopterin (10-propargyl-10dAM) compositions tested in xenograft models for their efficacy against human tumors are shown to be far superior to methotrexate ("MTX") and are even superior to the newer clinical candidate edatrexate ("EDX"). Moreover, 10-propragyl-10dAM showed a surprising ability to cure tumors such that there was no evidence of tumor growth several weeks after the cessation of therapy. Thus, highly purified compositions containing 10-propargyl-10dAM can be used to treat human tumors, particularly human mammary tumors and human lung cancer.
