简要总结
A multicenter, randomized, placebo-controlled, double-blind, phase III clinical trial will be conducted to explore the efficacy and safety of mecobalamin in the prevention of 2/3 HFS in patients with early breast cancer. 234 patients will be enrolled and will be randomized into mecobalamin group and placebo group at the ration of 1:1. The incidence of grade 2 / 3 HFS in the experimental group and the control group will be observed. This study is expected to provide evidence for clinical prevention of hand foot syndrome, improve clinical treatment guidelines for early breast cancer, and provide reference for other antitumor drugs for hand foot syndrome.
详细描述
Capecitabine is a drug recommended for adjuvant therapy in early breast cancer. The key to improving the prognosis of early breast cancer is to ensure that adequate treatment is sufficient. Hand foot syndrome Hand foot syndrome (HFS) is the most common and specific side effect of capecitabine, in which the incidence of grade 2 / 3 HFS requiring treatment is as high as 17-36%. At present, there is no specific drug for the treatment of HFS, and capecitabine must be reduced or stopped in case of grade 2 / 3 HFS. The guidelines also do not recommend standard drugs for the prevention of HFS. Mecobalamin is a derivative of vitamin B12, which can improve autonomic nervous system After symptoms and repair of small neuropathy, its clinical indication is the treatment of peripheral neuropathy.
A multicenter, randomized, placebo-controlled, double-blind, phase III clinical trial will be conducted to explore the efficacy and safety of mecobalamin in the prevention of 2/3 HFS in patients with early breast cancer. 234 patients will be enrolled and will be randomized into mecobalamin group and placebo group at the ration of 1:1. The incidence of grade 2 / 3 HFS in the experimental group and the control group will be observed. This study is expected to provide evidence for clinical prevention of hand foot syndrome, improve clinical treatment guidelines for early breast cancer, and provide reference for other antitumor drugs for hand foot syndrome.
