The primary objective of this study is to assess the long- term safety of prophylaxis with damoctocog alfa pegol in patients with hemophilia A in the real-world setting through the collection and analysis of adverse events (AEs) of special interest including those potentially indicative of PEG accumulation (hypersensitivity reactions, loss of drug effect, renal impairment, neurocognitive disorders, and inhibitor development), AEs, serious adverse events (SAEs), and adverse reactions (ARs). The secondary objective is to monitor the clinical effects of long-term exposure of prophylaxis damoctocog alfa pegol in 20904; HA-SAFE; v 1.0, 13 JAN 2020 Page 1 of 48 Reference Number: RD-SOP-1214 Supplement Version: 14 patients with hemophilia A, including assessments of kidney and liver function parameters, neurological function and patients’ PEG plasma levels.
