Single-centre experience of implementing physiotherapist-led prehabilitation for chimeric antigen receptor T cell therapy.

Introduction: This report outlines the evaluation of physiotherapist-led prehabilitation/rehabilitation for recipients of chimeric antigen receptor T (CAR-T) cell therapy.

Methods: A hybrid approach was used, incorporating in-person assessment of quality of life and functional capacity (6-min walk test and timed sit-to-stand test), and a personalised home exercise programme with remotely delivered physiotherapist support pre/post-admission.

Results: Functional deficits were prevalent at referral for CAR-T.

Outcome and feasibility of radiotherapy bridging in large B-cell lymphoma patients receiving CD19 CAR T in the UK.

Radiotherapy (RT) has potential synergistic effects with chimeric antigen receptor (CAR) T but is not widely used as bridging therapy due to logistical challenges and lack of standardised protocols. We analysed RT bridging in a multicentre national cohort of large B-cell lymphoma patients approved for 3L axicabtagene ciloleucel or tisagenlecleucel across 12 UK centres. Of 763 approved patients, 722 were leukapheresed, 717 had data available on bridging therapy.

Mucormycosis after CD19 chimeric antigen receptor T-cell therapy: results of a US Food and Drug Administration adverse events reporting system analysis and a review of the literature.

Chimeric antigen receptor (CAR) T-cell therapy leads to durable remissions in relapsed B-cell cancers, but treatment-associated immunocompromise leads to a substantial morbidity and mortality risk from atypical infection. Mucormycosis is an aggressive and invasive fungal infection with a mortality risk of 40-80% in patients with haematological malignancies. In this Grand Round, we report a case of mucormycosis in a 54-year-old patient undergoing CAR T-cell therapy who reached complete clinical control of Mucorales with combined aggressive surgical debridement, antifungal pharmacotherapy, and reversal of underlying risk factors, but with substantial morbidity from extensive oro-facial surgery affecting the patient's speech and swallowing.

Improved outcomes of large B-cell lymphoma patients treated with CD19 CAR T in the UK over time.

The success of CD19 Chimeric antigen receptor (CAR) T-cell therapy in large B-cell lymphoma (LBCL) has been partially offset by toxicity and logistical challenges, which off-the-shelf agents like CD20xCD3 bispecific antibodies might potentially overcome. However, when using CAR T outcomes as the 'standard-of-care comparator̕ for relapsed/refractory (r/r) LBCL, a potential learning curve with implementing a novel, complex therapy like CAR T needs to be considered. To address this, we analysed 726 UK patients intended to be treated with CD19 CAR T for r/r LBCL and compared outcomes between the first year of the national CAR T programme (Era 1; 2019) and the more recent treatment era (Era 2; 2020-2022).
