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

Study Purpose

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.

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.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Voluntarily participate in this study and sign the informed consent form. 2. Be aged between 18 and 70 years old (including the critical values), with no gender limitation. 3. Subjects with high-grade glioma diagnosed pathologically (referring to grade 3 or 4 in the "WHO (2021) Classification of Tumors of the Central Nervous System"), who have progressive disease during standard treatment or have recurrence after standard treatment. 4. Enhanced MRI shows space-occupying lesions in the brain, and there is at least one measurable lesion (according to the iRANO 2010 version criteria). 5. The tumor tissue of the patient has positive expression of B7-H3. The subject voluntarily provides the most recent formalin-fixed paraffin-embedded (FFPE) tissue or pathological sections (at least 8 consecutive blank sections) for the detection of B7-H3 expression (immunohistochemistry, IHC). 6. Have an expected survival period of ≥ 3 months. 7. Have a Karnofsky Performance Scale (KPS) score of ≥ 70 points.

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.

NCT06737146
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.
