Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
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.

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.
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.

|Recurrent Malignant Glioma|
This is a single-center, single-arm, open-label phase 1 study that will follow a 3 + 3 design of dose-escalating cohorts. The objectives of this study is to assess the safety and tolerability after administration of YYB-103 (IL13Rα2 targeted CAR-T cell) in patients with malignant glioma. YYB-103 is designed to target cancer cells expressing IL13Rα2 in cell surface. Only those subjects who are expressing IL13Rα2 and satisfy the inclusion and exclusion criteria will receive IV infusion of YYB-103. Long term follow-up study is evaluate the safety and exploratory efficacy of IP for 15 years from the date of IP administration in patients with malignant glioma refractory or recurrent to standard therapy who participated in this study. Subjects who participated in the Phase 1 study and received YYB-103 must have long-term follow-up for 15 years from the date of administration. During the long-term follow-up period, AEs, exploratory efficacy etc. are observed, and the observation period is every 6 months within 5 years and then yearly until 15 years.
Experimental: IL13Rα2 targeted CAR-T
Drug: - YYB-103
Biological: IL13Rα2 CAR-T cells Administration method: intravenous infusion YYB-103 is manufactured according to the subject's assigned dose group and body weight.
