ECOG ≤2 or KPS ≥60;\n3. Life expectancy ≥8 weeks as assessed by the investigator;\n4. Pathologically and\u002For histologically confirmed malignant tumors with brain, meningeal, and spinal cord metastases that have failed standard therapy or lack standard treatment options may be considered for enrollment;\n5. Intracranial metastases must meet the following characteristics:\n\n   Unresectable by craniotomy for solitary\u002Ffocal (≤3 lesions)\u002Fmultiple (\\>3 lesions) intracranial metastases; or inoperable leptomeningeal or spinal cord metastases; Inclusion Criteria Intracranial lesions that progressed after standard treatment, including whole-brain radiotherapy\u002Fstereotactic radiosurgery (WBRT\u002FSRS), and are not suitable for repeat radiotherapy;\n6. For brain\u002Fspinal cord parenchymal metastases, contrast-enhanced MRI must show at least one measurable lesion (according to iRANO criteria); for patients with meningeal lesions only, those deemed likely to benefit from this study by investigator judgment may also be considered for inclusion (efficacy assessed using RANO-LM criteria);\n7.

Pregnancy test must be negative for women of childbearing potential; both male and female subjects must agree to use effective contraception during treatment and for 1 year thereafter;\n9. Ability to understand trial requirements and procedures, and willingness to participate in the clinical study as required;\n10. Signing of the trial informed consent form.\n\nExclusion Criteria:\n\n1. Received central nervous system-directed radiation within 7 days prior to the first infusion of QH101;\n2. Patients with hematologic malignancies (such as lymphoma, leukemia, etc.) with central nervous system metastases;\n3. Patients with metastases in the brainstem and high cervical spinal cord, including midbrain, pons, medulla oblongata, and C1\u002F2 segments of the cervical spinal cord;\n4. Patients with significant mass effect from intracranial lesions and signs of increased intracranial pressure (such as severe headache, projectile vomiting, papilledema, altered consciousness, or imaging showing significant edema, midline shift ≥1 cm, compression of peribrain cisterns such as suprasellar cistern, quadrigeminal cistern, interpeduncular cistern, or ambient cistern);\n5. Patients with primary or secondary epilepsy\u002Fepileptic syndrome that is difficult to control with medication;\n6. Uncontrolled comorbidities, including but not limited to: ongoing or active infections, symptomatic congestive heart failure, unstable angina, arrhythmias, or psychiatric\u002Fsocial conditions limiting patient compliance with study requirements;\n7. Known psychiatric disorders or substance abuse disorders that may affect compliance with trial requirements;\n8. Currently receiving any other investigational treatments;\n9. Diagnosed with an immunodeficiency;\n10. Patients with active infections requiring systemic treatment;\n11. Inability to undergo magnetic resonance imaging (MRI);\n12. Severe cardiovascular damage: history of New York Heart Association (NYHA) class II or higher congestive heart failure, unstable angina, myocardial infarction or stroke within 6 months after first dosing, or clinically significant arrhythmias requiring treatment at screening;\n13. Allergic to immunotherapy or related cellular therapies;\n14. Previously received CAR-T or other cellular immunotherapies;\n15. Other reasons that the investigator considers make the patient unsuitable for participation in this study.","ALL","18 Years",{"count":64,"type":65},7,"ESTIMATED","INTERVENTIONAL",[68],"EARLY_PHASE1","QH101 is an allogeneic TCR-enhanced Vδ2 T cell therapy product engineered to express BTN protein-specific binding elements on the cell surface. This innovative approach harnesses the natural cytotoxic capabilities of Vδ2 T cells while augmenting their ability to recognize BTN proteins, thereby significantly improving tumor cell elimination efficiency. Notably, QH101 is designed without co-stimulatory signal domains or the CD3ζ domain, which prevents T cell exhaustion from overactivation and effectively enhances in vivo persistence.",[71,72,73],"Brain Metastasis","Meningeal Metastasis","Spinal Cord Metastasis",[75,76,77,78],"TCR","BTN","γδT","allogeneic cell therapy","NOT_YET_RECRUITING","2026-06-14",{"date":82,"type":83},"2026-06-18","ACTUAL",{"date":85,"type":65},"2026-05-31",{"date":87,"type":65},"2027-05-31",{"name":5,"class":6},1]
