Ocular adverse events following CAR-T cell therapy: A pharmacovigilance study and systematic review

The rise of immuno-oncology, including the use of chimeric antigen receptor T-cell (CAR-T) therapy is bringing in a new wave of cancer treatments, particularly in hematologic malignancies. However, data on their adverse events, particularly of the eye, is under-reported. To assess the ocular adverse events associated with the six FDA-approved CAR-T cell therapies, a disproportionality analysis utilizing the FAERS database was conducted from the first quarter of 2017 to the third quarter of 2023, as well as a systematic review of case reports of ocular events following CAR-T cell therapy up to December 20, 2023. A total of 53 ocular adverse events were identified from the FDAs FAERS database. The adverse events most frequently observed were mydriasis and xerophthalmia with tisagenlecleucel (Kymriah). The systematic review resulted in 8 case reports encompassing 19 patients which included a total of 27 events. This study demonstrates the importance of anticipation of potential ocular adverse events by ophthalmologists and oncologists as they can greatly contribute to morbidity in patients with cancer.
