This study is a randomized, double-blind, multicenter, placebo-controlled phase III clinical trial, aiming to evaluate the efficacy and safety of GM1 in preventing chemotherapy-induced peripheral neuropathy in breast cancer patients treated with Albumin-paclitaxel chemotherapy regimen.

This study was randomly divided into two groups at a ratio of 1:1, with 176 subjects in each group. All patients received GM1/ placebo treatment + chemotherapy.

The main purpose of this study is to evaluate the effectiveness of GM1 in preventing peripheral neuropathy caused by albumin-paclitaxel chemotherapy. The primary endpoint was the end of GM1 treatment in cycle 4 (C4D21), and the proportion of patients whose FACT/GOG-Ntx score changed by more than 12 points from baseline.

• Adequate organ function level
• Glycated hemoglobin (HbA1c) < 7.0%;
• For women of childbearing potential: use effective contraceptive measures for contraception from the date of signing the informed consent form until 30 days after the last use of the investigatory drug.
• Patients can accurately record or express the occurrence and severity of peripheral neuropathy through questionnaires.

Exclusion Criteria:

• Grade ≥1 peripheral neuropathy (CTCAE grade ≥1) or any of the first 4 items of FACT/GOG-Ntx ≥1;
• There are risk factors for peripheral neuropathy (excluding peripheral neuropathy caused by chemotherapy).
• History of another malignant tumors (except breast cancer)
• Symptoms such as muscle pain in the limbs that interfere with the evaluate of peripheral neuropathy;
