QH101 Cell Injection in Patients With Brain, Brain (Spinal) Meninges, and Spinal Cord Metastatic Malignant Solid Tumors
Exploratory Clinical Study of Dose Escalation for QH101 Cell Injection in Patients With Brain, Brain (Spinal) Meninges, and Spinal Cord Metastatic Malignant Solid Tumors Three Dose Groups Are Established: 1×10⁷ enTCR Vδ2T Cells Per Infusion (Low Dose), 3×10⁷ enTCR Vδ2T Cells Per Infusion (Medium Dose), and 6×10⁷ enTCR Vδ2T Cells Per Infusion (High Dose). The Dose Escalation Rules Are as Follows: The First Enrolled Subject Receives Low-dose Cell Infusion. If no Dose-limiting Toxicity (DLT) Events Occur After Infusion, the Second Enrolled Subject Receives Medium-dose Infusion; the Medium and Hig

Brief Summary
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.

Outcome Measures
Primary Outcomes (4)
AEs
Adverse events (AEs) are defined as any adverse medical events occurring from the onset of lumbar puncture catheter implantation in subjects (for subjects who had an Ommaya reservoir implanted before enrollment, events are recorded from the start of cell infusion) up to 12 months after the completion of QH101 infusion. Among these, cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) are graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) standards; graft-versus-host disease (GVHD) is graded according to the Mount Sinai Acute GVHD International Consortium definitions. Other AEs are graded according to the Common Terminology Criteria for Adverse Events (CTCAE, v5.0).
From the date of the subject's signing of the informed consent to one year following completion of treatment.
Neurological function assessment
Neurological function assessment is performed using the NANO scale. The NANO scale (see Appendix 2 for the NANO scale) assesses subjects' neurological symptoms across 9 domains: gait, muscle strength, upper limb ataxia, sensory function, visual field, facial strength, speech, consciousness status, and daily performance.Relative to the baseline or previous assessment, a total score change of -1 to +1 is defined as stable symptoms, a change of -2 to -3 as worsened symptoms, and a change of +2 to +3 as improved symptoms.
Prior to cell infusion, and at months 1, 3, 6, 9 and 12 post-infusion.
Cerebrospinal fluid cytology assessment
Cerebrospinal fluid tumor cell assessment and cerebrospinal fluid biochemical testing for cerebrospinal fluid cytology evaluation CSF cytological results are evaluated using a binary classification system. Negative results are defined as true negative or atypical, while positive results are defined as true positive or suspicious positive.
Prior to cell infusion, and at months 1, 3, 6, 9 and 12 post-infusion.
Neuroimaging Assessment
Neuroimaging assessment through imaging studies
Prior to cell infusion, and at months 1, 3, 6, 9 and 12 post-infusion.
Secondary Outcomes (3)
Quality of life assessment
Prior to cell infusion, and at months 1, 3, 6, 9 and 12 post-infusion.
Pharmacokinetics(PK)
Prior to cell infusion, and at months 1, 3, 6, 9 and 12 post-infusion.
Pharmacodynamics (PD)
Prior to cell infusion, and at months 1, 3, 6, 9 and 12 post-infusion.
Study Arms (1)
Patients with metastatic malignant solid tumors to the brain, meninges, and spinal cord
EXPERIMENTALPatients with malignant solid tumors metastasizing to the brain, meninges, or spinal cord receive QH101 cell injection solution via intrathecal injection or Ommaia reservoir infusion.
