Copaiba Mouthwash with Low-Level Laser Therapy to Prevent Mouth Sores After Stem Cell Transplant
Official title: Randomized, Double-Blind, Placebo-Controlled Phase II Study to Evaluate the Efficacy of a Copaiba-Based Mouthwash Combined With Low-Level Laser Therapy in the Prevention of Oral Mucositis in Patients Undergoing Hematopoietic Stem Cell Transplantation
Run by Instituto Nacional de Cancer, Brazil · NCT07810530 · Data updated 2026-11-12
This phase 2 trial tests whether a copaíba-based mouthwash, used four times daily, can help prevent oral mucositis in patients undergoing autologous hematopoietic stem cell transplantation.

Is this trial a fit for you?
✓Likely a good fit
Adults and adolescents 12 years and older undergoing autologous HSCT with no mucositis at day one of conditioning.
✕Probably not a fit
Patients with mucositis at baseline or those unable to adhere to the oral hygiene protocol may not benefit.

What this trial studies
This randomized, double-blind phase 2 study compares copaíba mouthwash versus placebo in autologous HSCT patients. Participants will use the assigned mouthwash four times daily and be evaluated daily for oral mucositis, oral pain, and swallowing difficulties. The trial aims to determine if Copaíba can reduce the incidence and severity of mucosal injury associated with high-dose chemotherapy and HSCT. Forty-six participants (23 per group) will be followed through the conditioning and early post-transplant period. The study is conducted at a single Brazilian center and is sponsored by Instituto Nacional de Cancer, Brazil.
Why it matters
Potential benefit: If successful, participants may experience less severe oral mucositis and associated symptoms during HSCT.
How similar studies have gone: Prior phase I data suggested potential benefit, and this phase II trial aims to confirm efficacy in a larger, blinded sample.
