<p>Anti-CD19 Chimeric Antigen Receptor (CAR) T-cell therapy is shifting the treatment paradigm internationally for selected patients with relapsed and refractory B-cell Non- Hodgkin Lymphoma. Despite high response rates with durable responses achieved in a significant proportion of patients, over 50% of patients will have progressed at one year following treatment with the currently licensed anti-CD19 CAR T-cell therapies. This modality of therapy is also associated with acute and potentially life-threatening toxicities, requiring strict risk mitigation strategies. In this thesis, the design, preparation and implementation of a new third generation anti-CD19 CAR T-cell Phase 1 trial entitled ENABLE, for patients with relapsed and refractory B-cell Non-Hodgkin Lymphoma, is described in detail. Following a literature review of CAR T-cell therapy in patients with B-cell Non-Hodgkin Lymphoma, the rationale for the ENABLE trial design is discussed, along with regulatory and clinical requirements for setting up CAR T-cell therapy in New Zealand. The importance of international collaboration to inform aspects of study design, CAR T-cell product manufacturing and developing CAR T-cell toxicity management protocols, has been demonstrated. The early clinical experience on the ENABLE trial is presented along with provisional safety, pharmacokinetic and efficacy data from the first participant treated. This is the first time that CAR T-cell therapy has been administered in New Zealand, demonstrating CAR T-cell expansion in vivo; but also highlighting the complexities of the CAR T-cell product manufacturing process and the importance of evaluating feasibility of CAR T-cell manufacturing, as a key secondary endpoint of the study. Further clinical experience on the ENABLE trial is crucial to develop the potential for CAR T-Cell therapy to be a safe, feasible and effective option for selected New Zealand patients in the future.</p>
