Derived from Biostar’s synthetic biology technology platform, Utidelone is a genetically engineered best-in-class epothilone analog and next-generation microtubule inhibitor. Utidelone injectable (UTD1) has been launched in China in 2021 for the treatment of metastatic breast cancer (MBC). It is the only approved new molecular of microtubule inhibitor in the past 10 years around the world.
Utidelone has different binding site from taxanes. Among all single agent or combination regimen of non-taxane chemotherapies, utidelone injectable is the only one to achieve both PFS and OS benefits for heavily pretreated MBC patients. It demonstrated several advantageous features, such as overcoming taxane-resistant, low hematological toxicity suitable for longer term exposure, ability to cross the blood-brain barrier that is able to prevent and treat tumor brain metastasis. Relevant study results were twice selected for oral presentations at ASCO annual meetings and published on Lancet Oncology and Annals of Oncology. Utidelone is recommended by “2023 CSCO Guidelines for Diagnosis and Treatment of Breast Cancer” as Class I (category IA) and listed in 2022 NRDL. It is expected to become the new standard of chemotherapy for MBC.
We keep expanding the indications, dose forms and global markets for utidelone. Utidelone injectable phase 3 studies for non-small-cell lung cancer (NSCLC) and breast cancer neoadjuvant and phase 2 studies for front-line gastric cancer and esophageal cancer are in recruitment in China; utidelone injectable registrational global MRCT studies for NSCLC and breast cancer are in initiation; utidelone capsule (UTD2) phase 1 studies for solid tumors are in progress in China and US in parallel.

Utidelone is a novel non-taxane microtubule stabilizer. It promotes microtubule formation while inhibits microtubule depolymerization, thereby inhibiting mitosis and triggering apoptosis of the cancer cells.
Utidelone has different binding site from taxane, and it’s NOT a P-glycoprotein substrate. Therefore, compared with taxane, utidelone have several advantages: 1) stronger affinity and better anti-tumor activity; 2) multidrug-resistant tumors including taxane-resistant tumors remain sensitive to utidelone; 3) high oral bioavailability and easily to be development into oral dosage form; 4) is able to cross the blood-brain barrier to prevent and treat tumor brain metastasis; 5) excellent safety profile. Significantly lower incidence of hematologic toxicity, milder hepatorenal toxicity, and controllable, reversible and quickly recovered peripheral neurotoxicity.
