Copaíba-based Mouthwash in Oral Mucotitis Prevention and Treatment in Oral Cancer Patients During Radioteraphy

Oral mucositis is the most significant acute toxicity of oral cavity radiotherapy. The available scientific evidence supports its preventive and therapeutic approach with low-level laser; however, this is unsuitable for tumor regions due to the risk of stimulating cellular metabolism. 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 patients undergoing radiotherapy for oral cavity tumors. Patients will be randomized into 2 groups: A (copaíba) and B (placebo) and will use the mouthwash 4x/day. Each group will have 20 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 the end of radiotherapy.

Efficacy of Ulinastatin for Reducing Radiation-Induced Oral Mucositis in Nasopharyngeal Carcinoma Patients

This is a phase 3, open-label, multicenter, randomized controlled phase III clinical trial. The purpose of this study is to evaluate the efficacy of ulinastatin, a kind of protease inhibitor, in the treatment of radiation-induced acute oral mucositis in localregionally advanced nasopharyngeal carcinoma(NPC) patients treated with concurrent chemoradiotherapy(CCRT). To Explore a new and efficient way to reduce the incidence and severity of radiation-induced acute oral mucositis.

Taurine for the Prevention and Treatment of Radiation-induced Oral Mucositis in Patients With Nasopharyngeal Carcinoma

This clinical trial aims to understand whether taurine can prevent and reduce severe radiation-induced oral mucositis in patients with nasopharyngeal carcinoma undergoing radiotherapy.

Multicentre Real-life Data Collection Study With CareMin650™ in the Prevention and Treatment of Oral Mucositis and Radio- and/or Chemo-induced Dermatitis

Most patients with cancer or haematological malignancies who receive chemotherapy - broadly defined to include targeted therapies and immunotherapy - and/or external beam radiotherapy may experience serious and disabling adverse events related to these treatments. Mucositis and radiodermatitis are a frequent and disabling complication of cancer and haematological malignancy treatments: chemotherapy (in the broadest sense: includes immunotherapy, targeted therapies) and/or radiotherapy, having a considerable impact on patients' quality of life. Mucositis is linked to lesions that occur in epithelial and connective tissues in response to a complex cascade of biological events involving the cellular elements of the mucosa. All these consequences make for an inadequate care pathway (hospitalisations and urgent care, complications, decompensations of comorbidities) and considerably increase the financial cost of patient care. Management strategies are perfectly codified, and photobiomodulation is now recommended internationally with a high level of evidence for the prevention and treatment of oral mucositis and radiodermatitis. Photobiomodulation (PBM), previously known as low-level laser therapy, has been used for decades in numerous therapeutic indications, based on major scientific knowledge and significant scientific and technological developments Including in fields such as aerospace or military medicine. CareMin650™ is a photobiomodulation medical device marketed since 2020 and indicated for the treatment of oral mucositis and radiodermatitis. The aim of the registry is to describe the real-life use of CareMin650™ in France in the preventive and curative treatment of radio and/or chemo-induced oral mucositis and radiodermatitis.

Aerosolized Mesenchymal Stem Cell-Derived Exosomes for the Prevention and Treatment of Radiation-Induced Oral Mucositis

Radiation-induced oral mucositis (RIOM) is an inevitable acute complication in radiotherapy for head and neck malignancies, characterized by a complex pathogenesis involving multiple biological processes. According to the latest data from the International Agency for Research on Cancer (IARC), approximately 650,000 new cases of head and neck cancers are diagnosed globally each year, with about 70% of patients undergoing radiotherapy. RIOM develops through a multistep pathophysiological cascade, including initiation of mucosal injury, signaling amplification, inflammatory response, ulceration, and eventual healing. Ionizing radiation induces DNA damage in oral mucosal epithelial cells, triggering increased apoptosis. This cellular injury promotes the activation and release of pro-inflammatory mediators such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6), compromising the integrity of the mucosal barrier and ultimately leading to ulcer formation. Current clinical management of RIOM remains largely supportive, relying on oral hygiene, nutritional supplementation, and pain control, with no effective prophylactic agents available. Despite extensive research into potential interventions internationally, no drugs specifically approved by the FDA or NMPA for the prevention of RIOM have reached the market. This significant unmet clinical need calls for urgent scientific and therapeutic advancement. This study aims to evaluate the therapeutic efficacy and safety profile of aerosolized exosomes derived from mesenchymal stem cells in the prevention and treatment of radiation-induced oral mucositis in patients receiving radiotherapy for head and neck cancers. The ultimate objective is to establish a novel and effective therapeutic strategy for clinical application.

Efficacy of N-acetylcysteine in Preventing Radiotherapy-Induced Oral Mucositis in Head and Neck Cancer Patients.

A prospective, randomized, controlled, parallel clinical trial will be conducted at Clinical Oncology and Nuclear Medicine Center at Mansoura University Hospital to assess the efficacy of N-acetylcysteine in the prevention of radiotherapy induced oral mucositis in Head and Neck cancer patients.
