Description: Tesetaxel is a semi-synthetic, orally bioavailable taxane derivative with potential antineoplastic and antiangiogenic properties. Tesetaxel binds to and stabilizes tubulin, promoting microtubule assembly and thereby preventing microtubule depolymerization. This may lead to cell cycle arrest and an inhibition of cell proliferation. This agent may also inhibit pro-angiogenic factors such as vascular endothelial growth factor (VEGF). As it represents poor substrate for P-glycoprotein-related drug resistance mechanisms, this agent may be useful for treating multi-drug resistant tumors.

Additional Information

Tesetaxel is a novel, orally absorbed, semi-synthetic taxane that is in the same class of drugs as paclitaxel and docetaxel. However, both prototype agents suffer from serious safety issues, particularly hypersensitivity reactions related to intravenous infusions that are occasionally fatal and that require careful premedication and observation. Other prominent side-effects of this drug class include myelosuppression (low blood counts) and peripheral neuropathy (disabling nerve damage). With administration as an oral capsule, tesetaxel was developed to maintain the high antitumor activity of the taxane drug class while eliminating infusion reactions, reducing neuropathy, and increasing patient convenience. The oral route also enables development of novel schedules that may expand dosing options when tesetaxel is used alone or in combination with other anticancer drugs. Preclinically, tesetaxel has demonstrated substantially higher activity against cell lines that were resistant to paclitaxel and docetaxel, since acquired resistance is not mediated by the multidrug-resistant p-glycoprotein. As a late Phase 2 oncology product, tesetaxel has demonstrated anticancer activity in its initial clinical trials, and the drug has not been associated with the severe infusion reactions that are linked with other taxanes. Moreover, unlike other oral taxanes, nerve damage has not been a prominent side effect of tesetaxel. Thus, the drug offers substantial opportunities to improve patient convenience, safety, and anticancer activity. More than 250 patients worldwide have been treated with oral tesetaxel in Phase 1 and Phase 2 clinical trials. For more information, please visit http://www.medicalnewstoday.com/articles/132058.php.
