Nafazatrom: clonogenic in-vitro assessment of activity against human malignancies.

Abstract:

:Nafazatrom was tested against a variety of human malignancies with the human tumor stem cell assay at one or more of the following concentrations: 1, 10, 25, and 100 micrograms/ml X 1 h or 0.05, 0.5, or 5 micrograms/ml by continuous exposure. Major (greater than or equal to 70%) inhibition was noted in 7/52 adenocarcinomas, in 0/9 squamous carcinomas, and 1/17 other malignancies. Intermediate levels of inhibition (50 to 69%) were noted in 7/52, 4/9, and 6/17 of these respective subtypes. No clear trend toward superiority of any dose-schedule was noted. Since nafazatrom has proven non-toxic in our nearly completed Phase I study, and since this study suggests activity against several human cancers, Phase II level testing is warranted.

  • Pharmacokinetic interaction involving sorafenib and the calcium-channel blocker felodipine in a patient with hepatocellular carcinoma.

    abstract::Sorafenib, an orally active multi-kinase inhibitor approved for the treatment of hepatocellular carcinoma (HCC), is primarily metabolized both via cytochrome P450 3A4 isoform (CYP3A4) and UGT1A9. Due to the contribution of these two biotransformation pathways, sorafenib is considered to be less susceptible than other ...
