Clinical Study of Mitoxantrone Hydrochloride Liposome Injection Combined With Capecitabine in Patients With HER-2 Negative Advanced Breast Cancer

To evaluate the dose-limiting toxicity of mitoxantrone hydrochloride liposome combined with capecitabine in patients with HER-2 negative advanced breast cancer who have received at least first-line treatment, explore the maximum tolerated dose (MTD) of mitoxantrone hydrochloride liposome, and determine the recommended phase II dose (RP2D).
