A Safety and Efficacy Study Evaluating CTX112 in Subjects With Relapsed or Refractory B-Cell Malignancies

Prior treatment

• Prior allogeneic hematopoietic stem cell transplant (HSCT).
• 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).
• 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.

Other illness

• Active or history of central nervous system (CNS) involvement by malignancy.
• History of a seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any autoimmune disease with CNS involvement.
• Presence of bacterial, viral, or fungal infection that is uncontrolled or requires IV anti-infectives.
• Active HIV, hepatitis B virus or hepatitis C virus infection.
• Primary immunodeficiency disorder or active autoimmune disease requiring steroids and/or other immunosuppressive therapy.

Other

• Women who are pregnant or breastfeeding.

• Age ≥18 years.
• Refractory or relapsed B cell malignancy.
• Eastern Cooperative Oncology Group performance status 0 or 1.
• Adequate renal, liver, cardiac and pulmonary organ function.
• 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.
