Use of dianhydrogalactitol and analogs or derivatives thereof in combination with platinum-containing antineoplastic agents to treat non-small-cell carcinoma of the lung and brain metastases

The use of dianhydrogalactitol provides a novel therapeutic modality for the treatment of non-small-cell lung carcinoma (NSCLC) and ovarian cancer, as well as other types of malignancy, including brain metastases of NSCLC. Dianhydrogalactitol acts as an alkylating agent on DNA that creates N7 methylation. Dianhydrogalactitol is effective in suppressing the growth of cancer stem cells and is active against tumors that are refractory to temozolomide, cisplatin, and tyrosine kinase inhibitors; the drug acts independently of the MGMT repair mechanism. Dianhydrogalactitol can be used together with other anti-neoplastic agents and can possess additive or super-additive effects.

Methods of determining acute myeloid leukemia response to treatment with farnesyltransferase inhibitors

The disclosed method rapidly identifies with desired accuracy AML patients, including elderly AML patients, likely to respond to treatment with a combination of a farnesyltransferase inhibitor and one or more of etoposide, teniposide, tamoxifen, sorafenib, paclitaxel, temozolomide, topotecan, trastuzumab and cisplatinum. In an embodiment, the improvements include the use of whole blood rather than the customary bone marrow sample, thus making the assay more accurate, rapid, less intrusive, less expensive as well as less painful. The method includes evaluation of a two-gene expression ratio (RASGRP1 :APTX), which with a corresponding threshold, provides sufficient accuracy for predicting the response to the combination treatment. In the preferred embodiment the combination treatment combines tipifarnib (Rl 15777, ZARNESTRA TM ) with etoposide. Further, the elderly AML patients identified as being likely responsive to the combination treatment with tipinifarb and etoposide have a complete recovery rate comparable to the best therapy available for younger patients.
