MT2020-24: A Phase 1 Dose Escalation and Cohort Expansion Study of the Safety and Efficacy of Anti-CD19 Allogeneic CRISPR-Cas9 Engineered T Cells (CTX110) in Subjects With Relapsed or Refractory B Cell Malignancies
Primary objective, Part A (dose escalation): To assess the safety of escalating doses of CTX110 in subjects with relapsed or refractory B cell malignancies to determine the recommended Part B dose Primary objective, Part B (cohort expansion): To assess the efficacy of CTX110 in subjects with relapsed or refractory B cell malignancies, as measured by objective response rate (ORR)
• For NHL patients: Age ≥18 years. For B cell ALL patients: age ≥18 years to ≤70 years
• Refractory or relapsed non-Hodgkin lymphoma, as evidenced by 2 or more lines of prior therapy, or histologically confirmed B cell ALL, refractory or relapsed.
• 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 CTX110 infusion.
• Agree to participate in an additional long-term follow-up study after completion of this study. Key
• Treatment with any gene therapy or genetically modified cell therapy, including CAR T cells.
• For NHL patients: prior allogeneic HSCT. For B cell ALL patients: prior allogeneic HSCT within 6 months, and/or any evidence of GvHD.
• 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.
• Previous or concurrent malignancy, except basal cell or squamous cell skin carcinoma, adequately resected and in situ carcinoma of cervix, or a previous malignancy that was completely resected and has been in remission for ≥5 years.
• For NHL patients: Use of systemic anti-tumor therapy or investigational agent within 14 days or 5 half-lives, whichever is longer, of enrollment. For B cell ALL patients: Use of systemic antitumor therapy within 7 days of enrollment.
• Primary immunodeficiency disorder or active autoimmune disease requiring steroids and/or other immunosuppressive therapy.
• Women who are pregnant or breastfeeding.
