In the case of females with childbearing potential, need to agree to use contraception during the treatment period and for at least 1 year after receiving study treatment. Participants must have a negative serum pregnancy test result at screening and a confirmed negative urine pregnancy test result prior to first CART treatment. Exclusion Criteria: 1. Any medical or psychiatric condition that, in the opinion of the investigator, may jeopardize the study participant or affect the study participant's ability to participate in this study; 2. A history of drug or alcohol abuse within the 12 months prior to baseline, or any condition that in the opinion of the investigator is associated with poor adherence; 3. Women who are breastfeeding or pregnant, or who plan to become pregnant at any time during the 12-month time period following treatment with CART, or a history of spontaneous or induced abortion within 4 weeks prior to screening; 4.
