About

Taxane-induced peripheral neuropathy (TIPN) caused by paclitaxel is a dose-limiting toxicity. The main symptoms of discomfort are numbness, tingling, and burning sensations in the glove-sock-like distribution of the limbs. At present, there are few effective methods for clinical treatment of TIPN, and there is no widely agreed consensus on effective treatment in the world. Therefore, it is of great clinical significance and practical value to carry out clinical research to explore drugs to relieve TIPN.

Full description

Taxane induced peripheral neuropathy (TIPN) caused by taxol is a dose limiting toxicity. The discomfort symptoms mainly include numbness, tingling and burning sensation in the glove sock like distribution of the extremities. This symptom can lead to limited activity, damage the self-care ability and social function of patients, and significantly reduce the quality of life of patients, At the same time, it may lead to early termination of chemotherapy and affect tumor treatment. The overall incidence of TIPN is very high. Many studies show that the incidence of TIPN is as high as 80%. CTCAE classifies it into 5 grades, and 25% - 30% of patients can have serious neurotoxicity. However, there are few effective methods for clinical treatment of TIPN, and there is no international consensus on effective treatment. Therefore, it is of great clinical significance and practical value to carry out clinical research on drugs to alleviate TIPN.

Monosialoganglioside (GM1), a member of the ganglioside family, is a kind of glycosylsphingolipid containing sialic acid on the cell membrane of mammalian animals. It is an endogenous substance. Gangliosides are mainly distributed in the outer layer of the cell membrane, especially on nerve endings and dendrites. It is most abundant and mainly expressed in the cell membrane of neurons. It participates in a variety of neurobiological activities, including neuronal differentiation Plasticity and cell survival. There is evidence that the application of GM1 can protect nerve cells, promote the recovery of neural function, and reduce the time of disability. Recent clinical studies on gangliosides have also shown promising results. GM1 effectively alleviates the neurotoxicity caused by docetaxel.

Although there have been previous studies on the effect of gangliosides on relieving the neurotoxicity of docetaxel, studies on the effect of gangliosides on relieving albumin bound paclitaxel have not been seen, and prospective clinical research data of large samples are lacking. In conclusion, the researchers hope to explore effective and reliable drugs to alleviate the peripheral neurotoxicity of albumin bound paclitaxel.

7. FACT-Ntx score is 44 points in the screening period
8. Sign the informed consent.

Exclusion criteria

1. There are any toxic events of the peripheral nervous system before enrollment, including: FACT-Ntx subscale score <44; ≥ 1 level of peripheral toxicity according to the CTCAE version 4.0 scale; all other pathological symptoms or diseases may affect Assessment of adverse neurotoxic effects;
2. Patients receiving other medications may cause similar adverse neurotoxic effects within 4 weeks before treatment with this regimen, or they may also receive neurotoxic medications at the same time. Including paclitaxel or analogues; vinca alkaloids or analogues; platinums or analogues; cytarabine, thalidomide, bortezomib or cabazine; other drugs or treatments may cause peripheral neurotoxicity;
3. Patients with poor overall condition and ECOG score> 1;
4. pregnant or lactating women;
5. Patients who also suffer from other neurological abnormalities cannot accurately record the occurrence and severity of neurotoxicity;
6. The patient is known to be allergic to the test drug or excipient ingredients of these products;
7. Patients with hereditary abnormalities of glucose and lipid metabolism (gangliopathies, such as idiopathic and retinopathy of triad families);
8. Patients not suitable for ganglioside treatment;
9. Patients with severe concurrent diseases may endanger safety and interfere with scheduled treatment, or the combination of diseases may affect the completion of the study, depending on the judgment of the investigator.
10. Patients with a clear history of neurological or mental disorders, including epilepsy or dementia.
