Study of a Copaiba-Based Mouthwash Combined With Low-Level Laser Therapy in the Prevention of Oral Mucositis in Patients Undergoing Hematopoietic Stem Cell Transplantation

Oral mucositis (OM) one of the most significant acute toxicity of Hematopoietic Stem Cell Transplantation (HSCT). There is already scientific evidence suporting OM the use of: low-level laser therapy (LLLT), cryotherapy (in autologous HSCT when conditioning regimens include high-dose melphalan), and keratinocyte growth factor (in autologous HSCT with high-dose chemotherapy associated with RT). In this sense, an alternative treatment becomes necessary. Based on the preliminary results of the phase I study, a double-blind, randomized phase II study is suggested to evaluate the effectiveness of copaiba-based mouthwash in the prevention of oral mucositis in HSCT was proposed. Patients will be randomized into 2 groups: A (copaíba) and B (placebo) and will use the mouthwash 4x/day. Each group will have 38 patients and be blind to the group in which they are included. They will be evaluated daily by a dental surgeon about oral mucositis, pain in the oral cavity and oropharynx, and dysphagia and will undergo daily laser therapy sessions, until neutropenic recovery.
