| description | <b>Background</b>: Oral mucositis (OM) is a common and debilitating complication of cancer therapy, particularly in patients undergoing chemotherapy and radiotherapy. It significantly impairs quality of life and may necessitate the interruption of cancer treatment. This study aimed to evaluate the efficacy and safety of OROSOL, an oral spray device, in managing oral mucositis in pediatric patients undergoing chemotherapy or radiotherapy. <b>Methods</b>: This randomized, double-blind, placebo-controlled clinical trial compared OROSOL to a placebo in children with oral mucositis aged 3 to 17 years. Participants were followed for 28 days with regular medical visits. The primary endpoints were changes in the Oral Assessment Guide (OAG) scores and key symptoms (mucositis score, difficulty in oral feeding, ulceration and erythema, and pain sensation). Safety was assessed via adverse events and local tolerability. <b>Results</b>: Both groups were demographically balanced at baseline (<i>p</i> > 0.6). OROSOL demonstrated significantly greater improvements in the mucositis score beginning on Day 7 (<i>p</i> = 0.0122) and maintained superiority through Day 28 (<i>p</i> = 0.0007). Notable reductions in mucositis severity were observed, with significantly faster relief in the OROSOL group compared to the placebo (<i>p</i> < 0.001 for most timepoints). Oral feeding difficulty also showed a marked decline, with significant improvements starting from Day 5 (<i>p</i> = 0.0153). Ulceration and erythema scores significantly decreased from Day 14 onwards (<i>p</i> = 0.0188). Pain sensation showed a marked reduction from Day 14 (<i>p</i> = 0.0014). No serious adverse events were reported, and tolerability was consistent across all participants. <b>Conclusions</b>: OROSOL has a significant impact on reducing mucositis severity, oral feeding difficulty, ulceration, erythema, and pain. Coupled with its excellent safety profile, it is a valuable therapeutic option. This treatment is particularly beneficial for pediatric patients, ensuring improved comfort and recovery without notable adverse effects. |
