Bleeds and resource use in hemophilia B: retrospective observational study.

To describe people with hemophilia B (PWHB) in the US who experience bleeds despite factor replacement therapy and to quantify the associated burden from the third-party payer perspective.... Observational study of adult male PWHB treated with factor IX replacement therapy identified from the PharMetrics Plus claims data from 2010 to 2019.... Patients with medically recorded bleeds (MRBs) were identified using diagnostic codes. Rates and rate ratios of inpatient admissions, emergency department (ED) visits, and outpatient visits among PWHB... There were 345 PWHB with MRBs and 252 without MRBs. More than half of PWHB with MRBs (56.8%) had 1 or more comorbidity vs 39.3% of PWHB without MRBs. The prevalence of anxiety and depression was high ... This study reports significant resource use and clinical burden among PWHB who seek medical care. PWHB with MRBs had considerable all-cause resource use compared with PWHB without MRBs. The prevalence...

The frequency of complications in a cohort of patients diagnosed with hemophilia A and hemophilia B receiving prophylactic treatment in Colombia: A retrospective noninterventional study.

Hemophilia A and B are disorders associated with the deficit of coagulation factors VIII and IX.... Was to determine the incidence of complications in a cohort of patients diagnosed with moderate and severe hemophilia A or B under treatment in a specialized institution.... A retrospective study of a cohort of patients with replacement therapy for hemophilia A or B, evaluating treatment and complications between January/2012 and July/2019. Sociodemographic, clinical and ... A total of 159 male patients were identified with hemophilia A (n = 140; 88.1%) and B (n = 19; 11.9%) with a mean follow-up of 5.9±2.3 years. The mean age was 23.6±16.1 years, hemophilia was reported ... The most common complication was joint bleeding which was expected in this type of patients. Low proportion of patients developed factor inhibitors during the follow up....

Model-Informed Support of Dose Selection for Prophylactic Treatment with Dalcinonacog Alfa in Adult and Paediatric Hemophilia B Patients.

Dalcinonacog alfa (DalcA), a novel subcutaneously administered recombinant human factor IX (FIX) variant is being developed for adult and paediatric patients with hemophilia B (HB). DalcA has been sho... A population PK model was built using adult data from two clinical trials (NCT03186677, NCT03995784). With allometry in the model, clinical trial simulations were performed to study alternative dosing... Almost 90% of the adults were predicted to achieve desirable FIX levels, i.e. 10% FIX activity, following daily 100 IU/kg dosing, with 90% of the subjects reaching target within 1.6-7.1 days. No every... This study supported the adult dose selection for DalcA in the presence of sparse data and enabled first-in-paediatric dose selection to achieve FIX levels that reduce risk of spontaneous bleeds....

Ninety patients with hemophilia A, with a mean age (SD) of 31.6 (14.4) years, and 10 patients with hemophilia B, with a mean age of 30.5 (20.6) years, were assessed. The most frequently affected joint... Skeletal complications are a common occurrence in hemophilia. Regular consultations with orthopedic specialists, focusing on bleeding control and hepatitis prevention, are essential for reducing the i...

Assessment of joint bleeding and target joints in patients with severe or moderately severe hemophilia B (factor IX ≤2%) receiving prophylaxis with rIX-FP in the PROLONG-9FP clinical trial program.

To assess the impact of prophylaxis with rIX-FP, a fusion protein linking recombinant factor IX (FIX) with human albumin, on joint outcomes.... Joint outcomes were assessed in pediatric (<12 years) and adult/adolescent (≥12 years) patients receiving rIX-FP prophylaxis every 7, 10, or 14 days; patients (>18 years) well-controlled on a 14-day r... For adult/adolescent (n = 63) and pediatric (n = 27) patients, median (Q1, Q3) annualized joint bleeding rate was 0.39 (0.00, 2.31), 0.80 (0.00, 2.85), 0.20 (0.00, 2.58), and 0.00 (0.00, 1.78) when tr... Prophylaxis with rIX-FP produced low joint bleeding rates and provided excellent hemostatic efficacy in the treatment of joint bleeds. All target joints reported resolved with rIX-FP prophylaxis....
