Clinical Study on the Safety and Efficacy of Novel Oncolytic Virus in the Treatment of Recurrent Malignant Glioma

Study Purpose

Glioma is the most common intracranial tumor. Among them, malignant glioma shows diffuse and infiltrating growth. Although it is given a comprehensive treatment such as surgery, radiotherapy and chemotherapy, it is prone to relapse, and there is an urgent need to explore new treatment methods. Oncolytic virus is currently the world's most cutting-edge treatment of glioma. On the basis of previous research on glioma and oncolytic virus (HSV-1), an engineered new oncolytic virus ON-01 containing CD gene has been constructed. In vitro and in vivo animal experiments have found that it has a good therapeutic effect on malignant glioma, and it has been approved by the ethics committee of Tiantan Hospital for its clinical research. This project intends to study the safety and effectiveness of ON-01 in the clinic on the basis of pre-clinical trials and preclinical research, clarify the oncolytic mechanism of ON-01 in the treatment of malignant glioma, and explore the dissolution of brain glioma. The new strategy of tumor virus treatment lays a theoretical foundation for the clinical promotion and application of ON-01 and product transformation.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06562621
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 1/Phase 2

Arms & Interventions

Arms

Experimental: ON-01/ONF

ON-01: 1ml intratumoral injection of ON-01. ONF: 100 mg/kg/day orally after operation for 20 consecutive days.

Interventions

Biological: - ON-01

ON-01 consists of a yeast cytosine deaminase (CD) gene. The CD gene converts the antifungal 5-flurocytosine (5-FC) to the anticancer drug 5-FU in cells that have been infected by ON-01.

Drug: - ONF

ONF is an extended-release formulation of flucytosine.
