SummaryProphylaxis is the recommended treatment for children with severe haemophilia A, but whether prophylaxis should be continued in adulthood is still under debate. Previous studies with limited follow-up have suggested that some patients may be able to stop prophylaxis in adulthood, while maintaining good joint health. This single-centre observational cohort study examined patients with severe haemophilia A born 1970–1988 without inhibitor development, and assessed the long-term consequences of discontinuing prophylaxis. Patient-initiated changes in prophylaxis, including all switches to on-demand treatment lasting a minimum of two consecutive weeks, were recorded from the time self-infusion began until the last evaluation. Sixty-six patients were evaluated at a median age of 32.4 years: 26 of patients had stopped prophylaxis for a median of 10 years, 15 had interrupted prophylaxis and 59 had continued prophylaxis. Annual joint bleeding rate (AJBR), Haemophilia Joint Health Score (HJHS-2.1; 0–124 points), radiological Pettersson score (0–78 points) and Haemophilia Activities List score (HAL; 100–0 points) were compared between patients who stopped and patients who continued prophylaxis. Although self-reported bleeding rates and functional limitations were similar in both groups (AJBR: 1.5 vs 1.2 and HAL: 84 vs 84 for those who stopped and continued prophylaxis, respectively), objective assessment of joint status showed increased arthropathy after 10 years of on-demand treatment in patients who stopped prophylaxis compared with those who continued (HJHS: 23 vs. 14 and Pettersson: 16 vs 5, respectively; P< 0.01). These results support continuation of long-term prophylaxis in adults and demonstrate the need for objective monitoring of joint status.Trial registration: Dutch Trial Registry number 3098; UTN U1111–1121–7069.

Safety And Efficacy

SummaryThe safety of full-length sucrose-formulated recombinant factor VIII (rFVIII-FS; KOGENATE® FS) for up to 24 months of use was evaluated in a postmarketing observational study in Europe. Long-term safety and efficacy data were available for 212 patients with severe haemophilia A, including 13 previously untreated patients (PUPs) and 12 patients with 1–19 exposure days (EDs). Patients accumulated a mean (± SD) of 187 (121) EDs to rFVIII-FS and received a total of 39,627 infusions, mainly for prophylaxis and for the treatment of 4,283 spontaneous or trauma-related bleeds during an average observation time of 710 (136) days. Of these bleeding episodes, 85.4% were successfully treated with one or two infusions of rFVIII-FS. Haemostasis was also evaluated during 46 minor to major surgical pro- cedures, and the response to infusion was “excellent” or “good” in all cases. FVIII inhibitor formation was observed in six patients (two de novo; four persistent or recurrent). The de novo cases represent 8.0% (2 of 25) of patients who reported 0–19 previous EDs at study entry. Four of the five patients who reported possible drug-related adverse effects developed inhibitors. The results of this observational study demonstrate the efficacy and safety of rFVIII-FS during normal clinical use in the treatment of patients with severe haemophilia A. Furthermore, these findings are consistent with those of previous phase III clinical studies with rFVIII-FS, particularly with regard to its efficacy and low incidence of inhibitor formation.
