A Multicenter, Randomized, Double-blind Phase II Trial to Evaluate GM1 Prevention of Peripheral Neuropathy in Patients With Breast Cancer

a Multicenter, Randomized, Double-blind Phase II Trial To Evaluate Monosialate Tetrahexose-ganglioside Sodium Injection (GM1) for Prevention of Peripheral Neuropathy in Patients With Breast Cancer Induced by Albumin-bound Paclitaxel Regimen Adjuvant/Neoadjuvant Therapy

This randomized, double-blind, multicenter, placebo-controlled Phase II trial was designed to investigate the efficacy and safety of GM1 in the prevention of peripheral neuropathy caused by albumin-bound paclitaxel regimen in breast cancer patients.This study was randomly divided into 3 groups at 1:1:1 with 50 subjects in each group Subjects received study treatment until the end of treatment for a total of 4/6 cycles. The treatment period was GM1/ placebo combined with albumin-bound paclitaxel therapy. GM1 / placebo was administered 1 day before administration (D0), on the day of administration (D1) and on the day after administration (D2), and albumin-bound paclitaxel was administered starting on day D1, with a total of 4/6 cycles.

6. Subjects (both male and female) agreed to use effective contraception from the time of signing the informed consent to 30 days after the last use of the study drug. Female subjects of childbearing age cannot be pregnant or lactating.
7. Patients can accurately record or express the occurrence and severity of neurotoxicity in questionnaires;
8. After enrollment, patients should not receive other treatments or care that might prevent or treat neurotoxic adverse events

Exclusion Criteria:

10. Known allergy to ganglioside drugs or any excipient component of such products; Or to treat an allergy to a drug or any excipient component of such product;
11. Patients who, in the judgment of the investigator, may increase the risk associated with the study, may interfere with the interpretation of the study results, or may be deemed unsuitable for inclusion by the investigator and/or sponsor.
