Characteristics and outcomes of patients enrolled in the Connect 360 benralizumab patient support programme in the UK: a retrospective cohort study.

BACKGROUND

Patient support programmes (PSPs) allow patients with chronic diseases to receive treatment and support at home. This study describes the Connect 360 PSP delivery and impact on patient-reported outcomes, satisfaction and adherence/persistence among benralizumab-treated patients with severe eosinophilic asthma (SEA).

METHODS

A non-interventional retrospective cohort study using data collected during routine care in the Connect 360 PSP. All consenting enrollees (≥18 years) were included in the study.

RESULTS

746 patients formed the study cohort. Mean (SD) age was 53.7 (14.5) years on PSP entry; 38.3% were female (38.7% unknown). 79.6% of patients were experienced biological therapy users. Oral corticosteroid (OCS) use was reported in 48.4% of patients at baseline and 34.8% at 48 weeks. 8.2% of patients reported asthma hospitalisation in the previous 6 months at 24 weeks vs 3.0% at 48 weeks. Mean (SD) 6-item Asthma Control Questionnaire (ACQ-6) scores were 2.7 (1.5) at baseline vs 1.6 (1.3) at 48 weeks. Mean (SD) patient satisfaction scores remained high (4.5 of 5 (1.0) at baseline; 4.7 of 5 (0.6) at 48 weeks). 28.3% of patients were considered adherent at 24 weeks, increasing to 98.3% when supplemented with sales/delivery data (sensitivity analysis). Discontinuation from PSP/benralizumab was low at 24 (3.4%/3.0%) and 48 (12.6%/5.8%) weeks.

CONCLUSIONS

Connect 360 PSP achieved high levels of satisfaction and persistence, with indications of positive outcomes including OCS use, hospitalisation and ACQ-6. The study was conducted during COVID-19, so it provides reassurance that patients with SEA receiving benralizumab may be supported safely and effectively at home.
