Utidelone (UTD1), an epothilone analogue recently approved in China for treating metastatic breast cancer, is recommended in conjunction with capecitabine for patients who have not responded to first-line therapies. Administration of the TRPA1 antagonist HC-030031 significantly alleviated mechanical and cold allodynia in the UTD1-induced pain model, as did two antioxidants, Mito-tempo and edaravone. This study proposes new approaches for mitigating pain caused by UTD1.
Furthermore, the proportions of apoptosis-positive cells and p-AMPKα-positive cells in the UTD1 group were significantly higher compared to the control group, while the levels of Ki-67 positivity were significantly reduced. UTD1 inhibits SCLC cell proliferation, induces G2/M phase arrest, and promotes cell apoptosis and autophagy through the activation of the ROS/AMPK signaling pathway.
Clinically, UTD1 + GEM demonstrated good tolerability, high disease control rates, and favorable immunophenotypic changes. These findings suggest UTD1 triggers ICD, enhancing immune recognition of tumor cells, and highlight its potential as a therapeutic strategy for PDAC.

This result was superior to the second-line treatment with nab-paclitaxel, which resulted in a PFS of 8 months and best overall response of stable disease with slight shrinkage. The present case indicates that a combination of utidelone with apatinib/anlotinib exhibited antitumor activity in a patient with HR+/HER2- mBC with BMs. Therefore, this combination offers a promising therapeutic option for the clinical treatment of patients with breast cancer and BMs.
