Canker sore, also known as aphthous stomatitis or ulcers and aphthae, is a common ailment, idiopathic in nature, with recurrent painful aphthous ulcers on the non-keratinized oral mucous membranes. Recurrent aphthous ulcer has higher prevalence in young adults and the frequency decreases with increasing age. The etiology of aphthous ulcer remains unclear. Other possible factors include trauma, drug use, deficiency in vitamin B12, folic acid, iron, stress, hormonal changes and metabolic diseases. Topical agents such as local antibiotics, local antiseptics, NSAIDs, and corticosteroids are generally prescribed for symptomatic relief. Several approved drug formulations such as pills, mouthwash, sprays and paste such as vitamin B12, chlorhexidine mouthwash, steroid lozenges and local anesthetics are primarily suggested for the treatment of aphthous ulcer. Despite the available local treatments, still sometimes oral canker sores may represent a painful burden for the patient and the gel OR-AT0222 may represent a topical product easy to use, well tolerated and effective local pain reliever, by facilitating the healing of the lesion(s). The Sponsor, Devintec Sagl, presents OR-AT0222, indicated for the management of canker sores, aphthous stomatitis and small lesions of the mouth. The gel forms a persistent protective film with a "barrier effect" that promotes wound healing and protects the lesions of the oral cavity from contact with external agents, providing pain relief and reducing the risk of further irritation.
