3. Eastern Cooperative Oncology Group performance status 0 or 1.
4. Adequate renal, liver, cardiac and pulmonary organ function.
5. Female subjects of childbearing potential and male subjects must agree to use acceptable method(s) of contraception from enrollment through at least 12 months after CTX112 infusion.

Key Exclusion Criteria:

3. History of a seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any autoimmune disease with CNS involvement.
4. Presence of bacterial, viral, or fungal infection that is uncontrolled or requires IV anti-infectives.
5. Active HIV, hepatitis B virus or hepatitis C virus infection.
6. Previous or concurrent malignancy in the last 3 years (with the exception of non-melanoma skin cancer and other cancers deemed by the investigator and medical monitor to be of low likelihood for recurrence).
7. Concurrent systemic treatment with an anticancer biologic (e.g., monoclonal antibody) within 30 days prior to CTX112 infusion or with a nonbiological anticancer drug within 14 days prior to CTX112 infusion.
8. Primary immunodeficiency disorder or active autoimmune disease requiring steroids and/or other immunosuppressive therapy.
