The study concluded that though the goal of zero bleed is achievable, patients still bleed
(Khair K et al. 2018).
• THUNDER Study
The THUNDER study analyzed the treatment patterns and outcomes in UK patients with
severe or moderate hemophilia A (SHA/MHA) in 2015. Inhibitors were present in 159 (8.8%)
SHA patients and 34 (3.9%) MHA patients. Of 717 non inhibitor patients with SHA or MHA
reporting HT compliant data during the study period, 563 (78.5%) had SHA, and 154 (21.5%)
MHA. The median (IQR) ABR in patients with SHA on prophylaxis was 2.0 (0.0 7.0) and 6.5
(2.0 17.8) on demand. The study showed that the ABR increased with age in both the
prophylaxis and on demand groups (Figure 4) (Scott MJ, et al. 2019).
