Abstract
OBJECTIVES
To investigate the risk of hemorrhage associated with Immune Checkpoint Inhibitors (ICIs) and characterize its clinical features.
METHODS
We systematically reviewed randomized clinical trials (RCTs) of hemorrhage related to ICIs and calculated odds ratios (ORs) with 95% confidence intervals (CIs). Pharmacovigilance studies were conducted by collecting ICIs-related hemorrhage cases from the FAERS database and assessing disproportionalities by reporting odds ratios (RORs) and information components (ICs).
RESULTS
A total of 79 RCTs involving 45,100 patients were finally included in the systematic review, with four published RCTs (n = 1965) and 75 unpublished RCTs (n = 43135). The primary analysis showed no significant difference in ICIs compared to the control group (OR 1.18 [95% CI 1.00-1.38], p = 0.05). In subgroup analyses, anti-PD-L1 combined with anti-CTLA-4 increased the risk of hemorrhage (OR 1.95, p = 0.03), and anti-CTLA-4 increased the risk of hemorrhage in the gastrointestinal system (OR 2.23, p = 0.04). 3555 cases of hemorrhage from the FAERS database were included in the disproportionate analysis, and the result suggested that ICIs increased the risk of hemorrhage (IC025 = 0.23).
CONCLUSION
Our study suggests that ICIs increase the risk of hemorrhage, and in particular, anti-CTLA-4 significantly increases the risk of hemorrhage in the gastrointestinal system.
