Key Points
Question
What are the incidence rates and risk factors for intraocular inflammation (IOI) and/or retinal vascular occlusion (RO) after brolucizumab treatment for neovascular age-related macular degeneration (AMD) in clinical practice?
Findings
In this cohort study of patient eyes with neovascular AMD treated with brolucizumab, the incidence rate for any form of IOI and/or RO was approximately 2.4%. A history of IOI and/or RO was a key risk factor for IOI and/or RO after brolucizumab treatment initiation.
Meaning
These early findings explore potential risk factors for inflammation-associated adverse events that may occur following real-world treatment with brolucizumab.

Background
This study describes a repeated measures prediction index to identify patients at high risk of ≥ grade 2 hand-foot skin reaction (HFSR) before each week of sorafenib therapy.
Methods
Data from 451 patients who received a sorafenib (400 mg bid) as part of a clinical trial were reviewed (Escudier B, Eisen T, Stadler WM et al. Sorafenib in advanced clear-cell renal-cell carcinoma. N Engl J Med 2007; 356: 125–134). Generalized estimating equations were used to develop the final risk model. A risk-scoring algorithm (range 0–58) was then derived from the final model coefficients. External validation was then carried out on a new sample of 1145 patients who received sorafenib under an expanded access program.
Results
Pretreatment white blood cell count, female gender, good performance status, presence of lung and liver metastases and number of affected organs were predictors for ≥ grade 2 HFSR. A nonlinear association between HFSR risk and treatment duration was also identified where risk was maximized at week 5 followed by a gradual decline. Before each week of therapy, patients with risk scores >40 would be considered at high risk for developing ≥ grade 2 HFSR.
Conclusions
The application and planned continued refinement of this prediction tool will be an important source of patient-specific risk information for the development of moderate to severe HFSR.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
