Patients with uncontrolled concomitant diseases or infectious diseases as judged by the investigator. 19. Subjects who have hypersensitivity to any component of LY-M003 injection. 20. Subjects who have previously received gene therapy or cell therapy of any kind. 21. Subjects who use systemic immunosuppressive agents or receive steroid therapy within 3 months prior to dosing (except for prophylactic immunosuppressive therapy as specified in protocol). 22. Subjects with history of cancer within 5 years prior to screening, except for completely resected non-melanoma skin cancer, non-metastatic prostate cancer and completely cured ductal carcinoma in situ. 23. Subjects who have vaccinated with attenuated live vaccine within 4 months prior to screening or plan to receive a live attenuated vaccine during the clinical trial. 24. Subjects who have received treatment or disposition with another investigational drug or investigational device within 28 days or 5 half-lives (drug only), whichever is longer, prior to screening. 25. Pregnant women (or women planning to become pregnant) or lactating women. 26. Other circumstances in which the investigator deems the subject inappropriate for study participation.
