Study of MT027 in Patients with Recurrent or Progressive High-grade Glioma

The clinical protocol plans to preset three dose groups, namely 1×10⁷ cells per dose, 3×10⁷ cells per dose, and 6×10⁷ cells per dose. The injection will be administered once every three weeks, adopting a "3 + 3" dose escalation design. The dosing interval is based on the pharmacokinetic (PK), safety and preliminary efficacy data of MT027 investigator-initiated trial (IIT) previously conducted at Dushu Lake Hospital of Soochow University. Accordingly, it is recommended to maintain the dosing interval of once every three weeks, with a window period of ±7 days. According to past experience, the dosing cycle should be at least 6 cycles, with each cycle lasting 21 days. If patients still benefit after more than 6 cycles, they can continue to receive the medication until no further benefit is achieved. The number of treatment sessions is approximately 6 to 9 times. However, the specific number of treatment sessions will generally be determined by the investigator based on the patient's disease condition.
