Summary
Advanced breast cancer is a special subtype of human breast cancer. Conventional guidelines recommend chemotherapy combined with other adjuvant therapies for this subtype of patients. However, the choice of treatment for these patients after treatment progress is a research hotspot in this field. Trastuzumab Deruxtecan (T-DXd) and Sacituzumab Govitecan (SG) are new ADC drugs targeting HER2 or TROP-2 with high efficacy and low toxicity after the progress of first-line treatment. The autophagy agents hydroxychloroquine or chloroquine has become the only FDA (Food and Drug Administration) approved autophagy inhibitor, and hydroxychloroquine and antibody-drug conjugate(ADC) may have synergistic effects based on the previous work results of our research group.
Therefore,we envisage that Trastuzumab Deruxtecan(T-DXd) or Sacituzumab Govitecan (SG) combined with hydroxychloroquine(HCQ) in the treatment of advanced breast cancer in clinical practice has the advantages of improving efficacy and survival.
To this end, we intend to conduct a prospective,multi-center, phase I/II clinical trial to evaluate the efficacy and safety of T-DXd or SG in combination with HCQ in patients with advacned breast cancer.
