PG - 182-192 LID - 10.1080/13696998.2022.2029088 [doi] AB - AIMS: Ocular toxicities are common adverse events (AEs) associated with anticancer agents. There is a paucity of data documenting their impact on patient care. This study assessed the clinical and economic burden of corneal AEs and related symptoms (collectively termed corneal AEs) in patients receiving multiple myeloma (MM) treatment. MATERIALS AND METHODS: Adults with a newly diagnosed MM (MM cohort) were identified from PharMetrics Plus, a US insurance claims database. Incidence, outpatient (OP) care, emergency department (ED) visits, hospitalizations, and costs were assessed for corneal AEs of interest: keratopathy/keratitis, blurred vision/decreased acuity, dry eye, eye pain, and photophobia. Incidence of new corneal AEs, healthcare resource utilization (HCRU), corneal AE-related HCRU, and costs were assessed and benchmarked against a hematology cohort of patients. RESULTS: The MM cohort included 2,120 patients with a median follow-up of 734.5 days. Overall, 11.7% of patients in the MM cohort and 7.4% in the hematology cohort had >/=1 corneal AE of interest. In the MM cohort, dry eye (6.1%), blurred vision/decreased acuity (3.4%), and keratopathy/keratitis (2.5%) were the most frequent. The overall median corneal AE-related per-patient-per-month (PPPM) cost was $27, predominantly contributed by OP care (median $19 PPPM). During follow-up, 4.8% of patients visited the ED, 3.6% were hospitalized, and 42.5% of patients visited an ophthalmologist/optometrist ( approximately 1.69 visits/year). Costs of these visits were negligible (median PPPM $19) compared to total all-cause costs (median PPPM $17,286). LIMITATIONS: The results can only be generalized to commercially insured and Medicare Advantage patients. Claims-based diagnosis of corneal AEs may underestimate true incidences. CONCLUSIONS: Corneal AEs were observed in approximately 12% of patients in the MM cohort, the most common were keratopathy/keratitis, dry eye, and blurred vision. Most of them required only OP care. The clinical and economic burden for treating corneal AEs was low when compared with total all-cause or MM-related PPPM costs.
