Time and Personnel Costs Associated with Adverse Event (AE) Management among Patients with Chronic Lymphocytic Leukemia (CLL)

Expert Review of Pharmacoeconomics & Outcomes Research, 2023


Novel therapies improve clinical outcomes in chronic lymphocytic leukemia (CLL), although adverse event (AE) profiles differ. This study evaluated time and personnel costs of AE management among healthcare professionals (HCPs) treating patients with CLL with novel therapies.


A non-interventional prospective survey was conducted over 2 months. Eligible HCPs reported the time per day spent performing AE management activities for CLL patients treated with acalabrutinib, ibrutinib, or venetoclax. Mean time and personnel costs (USD) per activity were summarized and used to estimate the total annual costs of AE management for an average-sized oncology practice.


For an average-sized practice (28 HCPs with an average of 56 CLL patients), the mean annual personnel cost of AE management for CLL patients on novel agents was estimated at $115,733. The personnel cost associated with acalabrutinib ($20,912) was less than half that of ibrutinib ($53,801) and venetoclax ($41,884), potentially due to fewer severe AEs and less time spent by oncologists managing AEs compared to other HCP types.


The substantial burden of AE management for patients with CLL may vary by treatment used. Acalabrutinib was associated with lower annual costs of AE management at an oncology practice level compared to ibrutinib and venetoclax.
