A Phase 1/2 Dose Escalation and Cohort Expansion Study of the Safety and Efficacy of Allogeneic CRISPR-Cas9-Engineered T Cells (CTX110) in Subjects With Relapsed or Refractory B-Cell Malignancies
This is a single-arm, open-label, multicenter, Phase 1/2 study evaluating the safety and efficacy of CTX110 in subjects with relapsed or refractory B-cell malignancies.
18 Years and up

2. Refractory or relapsed non-Hodgkin lymphoma, as evidenced by 2 or more lines of prior therapy.
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 CTX110 infusion.
6. Agree to participate in an additional long-term follow-up study after completion of this study.
Key Exclusion Criteria:

4. History of a seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any autoimmune disease with CNS involvement.
5. Presence of bacterial, viral, or fungal infection that is uncontrolled or requires IV anti-infectives.
6. Active HIV, hepatitis B virus or hepatitis C virus infection.
7. 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.
8. Use of systemic anti-tumor therapy or investigational agent within 14 days or 5 half-lives, whichever is longer, of enrollment.
