Candonilimab and ATRA Acid for Prevention of Oral Cancer Recurrence in Patients With OPL

February 20, 2025 updated by: Guopei Zhu, Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University

A Study of Candonilimab Combined With All-trans Retinoic Acid for Prevention of Oral Cancer Recurrence in Patients With High-risk Oral Precancerous Lesions.

The aim of this study is to involve high-risk patients with a history of malignant transformation in oral potentially malignant disorders. We will use a combination of Cardunil and all-trans retinoic acid for intervention. The effectiveness and safety of the combination therapy will be evaluated in the treatment of high-risk oral potentially malignant disorders, including the prevention of oral cancer recurrence and treatment of oral potentially malignant disorders. The findings of this study will provide evidence for tertiary prevention of oral cancer and the treatment of oral potentially malignant disorders.
