Lactobacillus Brevis CD2 Preventing Oral Mucositis


A pilot study on efficacy of Lactobacillus CD2 lozenges in preventing oral mucositis (OM) by high-dose chemotherapy with autologous hematopoietic stem cell transplantation. To test whether the probiotic Lactobacillus brevis CD2 lozenges can reduce the incidence and severity of high-dose chemotherapy conditioning regimen induced OM in patients undergoing HSCT. Clinical activity will be defined as reduction in the incidence of chemotherapy induced OM in the patients undergoing HSCT.
