| Summary: | Tom Blenkiron,1 Enrico Ferri Grazzi,1 Tom Burke,1,2 Maureen Watt,3 Kimberly H Davis3 1HCD Economics Ltd, Daresbury, UK; 2Faculty of Social Care, University of Chester, Chester, UK; 3Takeda Development Center Americas, Inc, Cambridge, MA, USACorrespondence: Enrico Ferri Grazzi, HCD Economics, Mere House, Brook Street, Knutsford, Daresbury, WA16 8GP, UK, Tel +44 1925 606475, Email enrico.ferrigrazzi@primeglobalpeople.comPurpose: To describe the demographic and clinical characteristics of patients with hemophilia A receiving different levels of treatment personalization (TP), and to assess the relationship between TP and sport active time (SAT).Patients and Methods: This post hoc analysis of the CHESS II study used data from physician-completed patient record forms and patient self-completion forms for adult males receiving prophylaxis for severe hemophilia A in Europe between November 2018 and October 2020. SAT was assessed using propensity score matching (PSM) across levels of TP, including pharmacokinetic (PK)-guided and non-PK-guided.Results: Of 54 patients, 32 (59.3%) received TP. Of these, 22 (68.8%) and 10 (31.3%) received non-PK-guided and PK-guided treatment, respectively. Median age varied between the TP and no-TP groups (29.5 and 34.0 years, respectively). Median (IQR) annual bleeding incidence was higher with non-PK-guided vs PK-guided TP (4.0 [3.0– 8.0] vs 3.5 [2.0– 4.0]). Median (IQR) problem joints were similar with non-PK-guided and PK-guided TP (1.0 [0.0– 1.0] and 1.0 [0.0– 2.0]). Patients in the TP vs no-TP group had higher median (IQR) SAT per month (3.3 [1.8– 6.2] vs 1.8 [0.7– 5.0] hours). Median (IQR) SAT per month was higher with PK-guided vs non-PK-guided TP (4.0 [3.0– 20.0] vs 3.0 [1.3– 5.3] hours). After controlling for confounding in the PSM model, SAT remained higher with TP vs no-TP and with PK-guided vs non-PK-guided TP. In both PSM models, P values were < 0.05 for the average treatment effect and < 0.01 for the average treatment effect on the treated. Sensitivity analyses confirmed the robustness of the PSM.Conclusion: Patients receiving TP vs no-TP had higher median SAT. Of those with TP, those receiving PK-guided vs non-PK-guided TP experienced lower bleeding rates and higher SAT. PK-guided TP may help patients to be more active, potentially gaining the clinical and psychosocial benefits of exercise.Keywords: exercise, pharmacokinetic-guided treatment, prophylaxis, quality of life, treatment personalization, hemophilia A |
