Each cohort will include 3 to 6 patients. Following the initial infusion, patients will be monitored for at least 28 days to assess safety, and subsequently followed for up to 2 years to evaluate long-term outcomes.\n\nPhase II (Dose Expansion) Based on the safety profile, persistence of LILRA6 CAR-T cells, and preliminary efficacy results observed in Phase I, the recommended dose and administration schedule will be established. Approximately 30 eligible patients will then be enrolled in the dose-expansion phase to further assess the safety and efficacy of LILRA6 CAR-T cell therapy at the selected dose. After the first infusion, all patients will continue in long-term follow-up for up to 2 years post-treatment.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
