About BRG01

EBV is a human herpesvirus and has infected about 95% of population worldwide. It has been listed as Group 1 carcinogen ("Carcinogenic to humans") by World Health Organization (WHO) and proved to be associated with a range of diseases including nasopharyngeal cancer,EBV-positive gastric cancers,lymphoma and lymphoproliferative diseases. As one of the most common head and neck tumors,nasopharyngeal cancer,an epithelial carcinoma arising from the nasopharyngeal mucosal lining,is closely related to EBV infection. According to WHO,an estimated number of 133,000 new cases of nasopharyngeal cancer worldwide was reported in 2020; 50% of which was diagnosed in China. South China provinces such as Guangdong and Guangxi provinces make up for more than 60% of nasopharyngeal cancer patient population.

BRG01 Therapy developed by Biosyngen is an engineered T cell therapy,also known as a type of adoptive immune cell therapy for nasopharyngeal cancer treatment. Patients' T cells were isolated and genetically modified in a GMP-compliant facility to enhance their ability to recognize and attack specific antigens on cancer cells. The modified T cells are expanded ex vivo and infused back into the patient. The infused T cells would bind to the specific antigen on the cancer cells to mediate tumor killing. The preliminary safety and efficacy of BRG01 Therapy have been demonstrated in data from exploratory clinical trials.
