  • Patent number: 11717505
    Abstract: Methods for treating diffuse intrinsic pontine glioma (DIPG) comprising administration of a therapeutically effective amount of an alkylating hexitol (such as dianhydrogalacitol, diacetyldianhydrogalacitol, and dibromodulcitol) are disclosed. Such methods may further comprise administration of other anti-cancer agents. In preferred embodiments, the secondary anti-cancer agent is an inhibitor of Wee1 tyrosine kinase (such as adavosertib).

  • Patent number: 11541027
    Abstract: 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.

  • Patent number: 11446274
    Abstract: The use of dianhydrogalactitol provides a novel therapeutic modality for the treatment of malignancies of the central nervous system in pediatric patients, including glioblastoma multiforme (GBM) high grade glioma, and medulloblastoma. Dianhydrogalactitol acts as an alkylating agent on DNA that creates N7 methylation and that can induce double-stranded breaks in DNA. 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 (e.g. cisplatin) and can possess additive or super-additive effects.
