Drug Duo of Ixabepilone and sunitinib Kills Chemotherapy-resistant Ovarian Cancer Cells......

In continuation of Sunitinib...

The use of two drugs never tried in combination before in ovarian cancer resulted in a 70 percent destruction of cancer cells already resistant to commonly used chemotherapy agents, say researchers at Mayo Clinic in Florida. Research  suggests that this combination (ixabepilone and sunitinib), might offer a much needed treatment option for women with advanced ovarian cancer. When caught at late stages, ovarian cancer is often fatal because it progressively stops responding to the chemotherapy drugs used to treat it. The finding also highlights the importance of the role of a molecule, RhoB, that the researchers say is activated by the drug duo. Neither drug is approved for use in ovarian cancer. Ixabepilone is a chemotherapy drug that, like other taxane drugs, targets the microtubules and stops dividing cells from forming a spindle. It has been approved for use in metastatic breast cancer. Sunitinib, approved for use in kidney cancer, belongs to a class of tyrosine kinase inhibitors that stops growth signals from reaching inside cancer cells.
