Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an open-label, multicenter, Phase 1/2 study evaluating the safety and efficacy of CTX112™ in subjects with relapsed or refractory B-cell malignancies.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an open-label, multi-center Phase 1/2 study of CTX112 in subjects with relapsed/refractory B cell malignancies. CTX112 is an is allogeneic CD19-directed chimeric antigen receptor (CAR) T cell immunotherapy comprised of allogeneic T cells that are genetically modified ex vivo using CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats/ CRISPR associated protein 9) gene editing components (single guide RNA and Cas9 nuclease).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age ≥18 years.
2. Refractory or relapsed B cell malignancy.
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.

Exclusion Criteria

1. Prior allogeneic hematopoietic stem cell transplant (HSCT).
2. Active or history of central nervous system (CNS) involvement by malignancy.
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.
9. Women who are pregnant or breastfeeding.
