ATHN Transcends: A Natural History Study of Non-Neoplastic Hematologic Disorders

In parallel with the growth of ATHN's clinical studies, the number of new therapies for all blood disorders is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have not yet demonstrated long-term safety and effectiveness beyond the pivotal trials that led to their approval. In addition, results from well controlled, pivotal studies often cannot be replicated once a therapy has been approved for general use.2,3,4,5 In 2019 alone, the FDA has issued approvals for 24 new therapies for congenital and acquired hematologic conditions.6 In addition, almost 10,000 new studies for hematologic diseases are currently registered on www.clinicaltrials.gov.7 With this increase in potential new therapies possible, it is imperative that clinicians and clinical researchers in the field of non-neoplastic hematology have a uniform, secure, unbiased, and enduring method to collect long-term safety and efficacy data. As emphasized in a recently published review, accurate, uniform and quality national data collection is critical in clinical research, particularly for longitudinal cohort studies covering a lifetime of biologic risk.8

Efanesoctocog Alfa Prophylaxis in Patients With Hemophilia A With Synovial Hypertrophy

The objective of the study is to assess the improvement of synovial hypertrophy during the 12 months of efanesoctocog alfa prophylaxis once per week (QW) in joints with existing evidence of synovial hypertrophy in participants with hemophilia A. The study duration for each participant is approximately 12 months.

The European Paediatric Network for Haemophilia Management ( PedNet Registry)

Rationale: Haemophilia is a rare disease; to improve knowledge international collaboration is needed. Well-defined clinical data will be collected from complete cohorts in order to prevent selection bias. Objective: To collect data on bleeding during neonatal period, endogenous (genetic) and exogenous (treatment-related) determinants of inhibitor development and long term outcome.
