Brief Summary:
This is an open-label, multicenter, Phase 1 study evaluating the safety and efficacy of CTX110 in subjects with relapsed or refractory B-cell malignancies.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| B-cell Malignancy Non-Hodgkin Lymphoma B-cell Lymphoma Adult B Cell ALL | Biological: CTX110 | Phase 1 |
The study may enroll up to 143 subjects in total. CTX110 is a CD19-directed chimeric antigen receptor (CAR) T cell immunotherapy comprised of allogeneic T cells prepared for the treatment of B cell malignancies. The cells are from healthy adult volunteer donors 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).

Primary Outcome Measures :
- Part A (Dose Escalation), for all cohorts: Incidence of adverse events, defined as dose-limiting toxicities [ Time Frame: From CTX110 infusion up to 28 days post-infusion ]
- Part B (Cohort Expansion), for NHL: Objective response rate [ Time Frame: From CTX110 infusion up to 60 months post-infusion ]
Secondary Outcome Measures :
- Duration of Response [ Time Frame: From date of first objective response of CR/PR until date of disease progression or death due to any cause, assessed up to 60 months ]Duration of Response (DOR) will only be reported for subjects who have had CR/PR events
- Duration of Clinical Benefit (DOCB) [ Time Frame: From date of first objective response of CR/PR until the relapse or death that followed the last response, assessed up to 60 months ]
- Progression Free Survival [ Time Frame: From date of CTX110 infusion until date of disease progression or death due to any cause, assessed up to 60 months ]
- Overall Survival [ Time Frame: From date of CTX110 infusion until date of death due to any cause, assessed up to 60 months ]
- Objective Response Rate (for B cell ALL) [ Time Frame: From CTX110 infusion up to 60 months post-infusion ]For B cell ALL, objective response rate (ORR) (complete remission + complete remission with incomplete blood count recovery [CRi]) will be assessed.
