Background:
Mantle cell lymphoma (MCL) is a type of B-cell lymphoma that is currently incurable. Pirtobrutinib shows promising response rates in heavily pretreated MCL patients according to the approval study, but the real-world data are scarce.
Methods:
In this study, we retrospectively analyzed the efficacy and safety profile of pirtobrutinib in 10 relapsed/refractory MCL patients from compassionate use program (CUP).
Results:
On average, the patients underwent three lines of systemic therapy prior to pirtobrutinib and were predominantly BTKi exposed (9/10). The best overall response rate (BORR) was 67%. In a median follow-up of 8.6 months, the mean duration of response (DOR), progression-free survival (PFS), and overall survival (OS) were not reached. No new safety signals were documented.
Conclusions:
In summary, pirtobrutinib represented a safe and effective treatment option in a small real-world population.
