Effect of GM1 in Prevention of Taxanes Induced Neurotoxicity in Operable Breast Cancer
Study Details
Study Description
Brief Summary
Background: Taxane plays a key role in the treatment of breast cancer and taxane-induced peripheral neuropathy (TIPN) is a dose-limiting adverse effect leading to treatment discontinuation. Ganglioside-monosialic acid (GM1) functions as a neuroprotective factor. However, the effects of GM1 on TIPN in breast cancer patients remains unknown.
Purpose: This randomized phase III trial is designed to evaluate the potential effects of GM1 for preventing TIPN in breast cancer patients.

Detailed Description
Introduction： Taxanes is a key agent in the treatment of breast cancer. However, peripheral neuropathy markedly limits the use of taxanes. Unfortunately, current studies have neither revealed a clear mechanism nor established an effective treatment for Taxane-induced peripheral neuropathy (TIPN). Monosialotetrahexosyl ganglioside (GM1) functions as a neuroprotective factor. This multi-center, randomized, placebo-controlled trial was performed to assess the efficacy of GM1 fo preventing taxanes induced neurotoxicity in operable breast cancer patients who received taxanes-based adjuvant chemotherapy.
OBJECTIVES:
Primary Objective:
To evaluate the efficacy of gangliosides in the prevention of neurotoxicity in breast cancer patients treated with taxane-based chemotherapy. That is, to compare the differences in the scores of Functional Assessment of Cancer Treatment Neurotoxicity (FACT-Ntx) between the patients treated by GM1(the treatment group) and the placebo (the control group) at 2 weeks after completion of 4-cycles of taxane-based chemotherapy.
Secondary
-
To compare the differences in the scores of Eastern Cooperative Oncology Group neuropathy scale between the patients treated by gangliosides (the experimental group) and the placebo (the control group);
-
Tocompare the incidence of neurotoxic adverse events caused by taxane-based chemotherapy. That is, the difference between the patients of chemotherapy treated by gangliosides (the experimental group) and the placebo (the control group) in terms of the incidence of neurotoxicity (graded according to the NCI-CTCAE version 4.0 grading scale);
-
Assess the safety and tolerance of the two treatment groups (ganglioside and placebo groups).
OUTLINE: This is a randomized, double-blind, placebo-controlled study. Patients with early-stage breast cancer planning to receive taxane-based adjuvant chemotherapy were randomly assigned to receive GM1 (80 mg, Day -1 to Day 2) or placebo treatment.
Treatment group: Monosialotetrahexosylganglioside sodium is added into 250 mL of 0.9% sodium chloride injection, which is given once a day via intravenous drip infusion for 3 days. The first dose is given at 1 day before the start of the chemotherapy. At the same time, the patients are treated with a taxane-based chemotherapy selected by the investigators.
Placebo group: Placebo is added into 250 mL of 0.9% sodium chloride injection, which is given once a day via intravenous drip infusion for 3 days. The first dose is given at 1 day before the start of the chemotherapy. At the same time, the patients are treated with a taxane-based chemotherapy selected by the investigators.
The screening and baseline peripheral neurotoxicity assessment was performed 1 day before the start of the first course of taxane-containing chemotherapy.
The subjects will be treated by the study drugs according to the schedule until the completion of established taxane-based adjuvant chemotherapy, the onset of unacceptable toxicity, or when the patient withdraw from the study voluntarily.
Endpoint assessments including FACT-Ntx subscale, CTCAE version 4.0 grading scale and ENS subscales were performed at 2 weeks after each course of chemotherapy. Additional long-term assessments were performed at 3 months, 6 months and 1 year after the end of chemotherapy. The follow-up will be carried out until 2 years after the enrollment time of the last patient.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Ganglioside-monosialic acid arm Patients will receive treatment of adjuvant chemotherapy. Ganglioside-monosialic acid(GM1, 80mg per day) will be given at 1 day before the start of chemotherapy for three days (Day -1, 1 and 2). Chemotherapy regimens: Epirubicin (90 mg/m2) combined with cyclophosphamide (600 mg/m2) followed by paclitaxel (175 mg/m2 *4 cycles) after four courses of chemotherapy; Epirubicin (90 mg/m2) combined with cyclophosphamide (600 mg/m2) followed by docetaxel (75 mg/m2 *4 cycles) after four course of chemotherapy; Docetaxel (75 mg/m2 q21d) combined with cyclophosphamide (600 mg/m2) for four courses. The first day (D1) of each cycle is treated with taxane-based chemotherapy. 14-21 days are usually as one cycle. The methods of pretreatment and hydration shall be decided by the physicians. |
Drug: Ganglioside-monosialic acid
Ganglioside-monosialic sodium is added into to 250 ml of 0.9% sodium chloride injection, which is given once a day via intravenous drip infusion for 3 days. The first dose is given at 1 day before the start of the chemotherapy.(day -1, day 1 and day2). The dosages of GM1 are 80mg per day.

| Placebo Comparator: placebo arm Patients will receive treatment of adjuvant chemotherapy. Placebo will be given at 1 day before the start of chemotherapy for three days (Day -1, 1 and 2). Chemotherapy regimens: Epirubicin (90 mg/m2) combined with cyclophosphamide (600 mg/m2) followed by paclitaxel (175 mg/m2 *4 cycles) after four courses of chemotherapy; Epirubicin (90 mg/m2) combined with cyclophosphamide (600 mg/m2) followed by docetaxel (75 mg/m2 *4 cycles) after four course of chemotherapy; Docetaxel (75 mg/m2 q21d) combined with cyclophosphamide (600 mg/m2) for four courses. The first day (D1) of each cycle is treated with taxane-based chemotherapy. 14-21 days are usually as one cycle. The methods of pretreatment and hydration shall be decided by the physicians. |
Drug: placebo
Placebo is added into to 250 ml of 0.9% sodium chloride injection, which is given once a day via intravenous drip infusion for 3 days. The first dose is given at 1 day before the start of the chemotherapy.(day -1, day 1 and day2).

Outcome Measures
Primary Outcome Measures
- the Functional Assessment of Cancer Treatment Neurotoxicity (FACT-Ntx) subscale between groups at 2 weeks after the 4-cycle chemotherapy [Day 1 of Week 1 to 1 year after the last course of chemotherapy]
The primary endpoint was assessed using the Functional Assessment of Cancer Treatment, Gynecologic Oncology Group Neurotoxicity (FACT -Ntx) subscale at 2 weeks after completion of 4-cycles of taxane-based chemotherapy. FACT-Ntx subscales contains 11 items including numbness, tingling, and discomfort in the hands or feet; difficulty hearing or tinnitus; joint pain or muscle cramps; weakness or fatigue; or trouble walking, buttoning buttons, or feeling small shapes when placed in the hand; feeling pain or hard to breath when exposed to low temperature. Each Items is scored from 0 to 4 with a total score of 44; higher scores indicate better performance. A 5-point difference in the FACT-Ntx subscale scores between groups is considered clinically meaningful. The FACT-Ntx subscales assessments were performed at 2 weeks after each course of chemotherapy. Additional long-term assessments were performed at 3 months, 6 months and 1 year after the end of chemotherapy.
Secondary Outcome Measures
- neurotoxicity evaluated by NCI-CTCAE version 4.0 grading scale [1 monthDay 1 of Week 1 to 1 year after the last course of chemotherapy]
neurotoxicity evaluated by NCI-CTCAE version 4.0 grading scale which classified symptoms as grade 0, 1, 2, 3, or 4. Higher scores indicate more severe neurotoxicity. The NCI-CTCAE version 4.0 assessments were performed at 2 weeks after each course of chemotherapy. Additional long-term assessments were performed at 3 months, 6 months and 1 year after the end of chemotherapy.
- neurotoxicity evaluated by the Eastern Cooperative Oncology Group neuropathy scale (ENS) subscales of sensory neuropathy, motor neurotoxicity, and neurogenic constipation. [Day 1 of Week 1 to 1 year after the last course of chemotherapy]
The ENS subscales (from 0 to 4 scale) of sensory neuropathy, motor neurotoxicity, and neurogenic constipation were examined. For each of these scales, lower scores indicate better performance. The ENS subscales assessments were performed at 2 weeks after each course of chemotherapy. Additional long-term assessments were performed at 3 months, 6 months and 1 year after the end of chemotherapy.
