Health-related quality of life in patients given ciltacabtagene autoleucel for relapsed or refractory multiple myeloma (CARTITUDE-1): a phase 1b-2, open-label study

Thomas Martin et al. Lancet Haematol. 2022 Dec.

Abstract

Background: CARTITUDE-1 is a phase 1b-2 study evaluating ciltacabtagene autoleucel (cilta-cel), a chimeric antigen receptor T cell therapy with two B-cell maturation antigen-targeting single-domain antibodies, in patients with relapsed or refractory multiple myeloma. Primary efficacy outcomes have previously been reported. Here, we report health-related quality of life (HRQOL) secondary outcomes evaluated using patient-reported outcomes.

Methods: This single-arm, open-label, phwase 1b-2 study was done at 16 centres in the USA. Patients were aged 18 years or older with diagnosis of multiple myeloma and Eastern Cooperative Oncology Group performance status of 1 or less with three or more previous lines of therapy, or were double refractory to a proteasome inhibitor and immunomodulatory drug, and had received a proteasome inhibitor, immunomodulatory drug, and anti-CD38 antibody. A single cilta-cel infusion (target dose 0·75 × 106 CAR+ T cells per kg) was administered 5-7 days after lymphodepletion. Patient-reported outcomes were assessed using the European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaire core 30-item, pre-specified items from the EORTC myeloma module, and EuroQol five-dimensional descriptive system questionnaire. Clinically meaningful changes in patient-reported outcomes were defined by anchor-based minimally important differences. This trial is registered with ClinicalTrials.gov, NCT03548207. This trial is completed but feeding into a long-term follow-up study.

Findings: Between July 16, 2018, and Oct 7, 2019, 78 patients were enrolled and underwent apheresis in phase 2 of the study. 68 patients were treated (43 [63%] male, 49 [72%] White), and their patient-reported outcomes assessed (median follow-up 16·9 months, IQR 15·7-17·5). After infusion, a transient decline was observed, followed by improvements in global health status (mean change from baseline to day 464 +8·0 points, SD 20·9), physical (+4·6 points, 21·1), and emotional functional scales (+1·9 points, 23·7) over time, and declines for symptom-based scores (-14·1 pain, SD 31·5 and -15·4 fatigue; SD 29·5), indicating improved patient HRQOL following treatment with cilta-cel.

Interpretation: These durable HRQOL improvements are consistent with clinical findings, in which a single cilta-cel infusion led to substantial and durable responses in heavily pre-treated patients with relapsed or refractory multiple myeloma. These results support the use of cilta-cel in patients with relapsed or refractory multiple myeloma.
