Brief summary
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
Detailed description
This is a longitudinal, natural history observational cohort study being conducted at approximately 150 ATHN-affiliated sites with a target accrual of 3,000 participants. Participants will be followed for a minimum of 15 years on an assigned arm within a cohort; however, arm or module participation may last longer, and participants will continue participation in the arm or module for its duration. Harmonized data elements will be collected at the time of enrollment, semi-annually (every 6 months), annually, ad hoc, and as defined by the terms of individual arms and modules. Data will be collected for participants enrolled in cohort-specific arms and modules. Each participant will be assigned to a single cohort: Hemophilia, von Willebrand Disease, Congenital Platelet Disorders, Rare Disorders, Bleeding Not Otherwise Specified (NOS), Thrombosis/Thrombophilia, or Non-Neoplastic Hematologic Conditions. Study arms and study modules are developed to advance the exploration of blood disorders disease specific insights by ATHN and its partners. Arms may branch off into product-specific data collection via Modules to be collected during the study, in conjunction with planned study assessments.

Efanestoctocog alfa (ALTUVIIIO®) Module The purpose is to investigate the safety, tolerability, and effectiveness of efanesoctocog alfa (ALTUVIIIO®) in PUPs with severe hemophilia A. INHIBIT Module This is an observational study assessing the rate of inhibitor formation in young children with severe hemophilia A in the current treatment era. Hemophilia Natural History Arm This Arm is investigating the safety, effectiveness, and practice of treatment for people with hemophilia. Emicizumab (Hemlibra®) Module All participants treated with Hemlibra® are eligible to participate. Distress Module Participants with Congenital Hemophilia A or B, 18 years of age or older, will be followed longitudinally for 2 years or from time of enrollment for a total planned study duration of 3 years Nonacog beta pegol (Rebinyn®) Module The Rebinyn® Module is a prospective study in hemophilia B participants without inhibitors. Hemophilia Gene Therapy Outcomes Arm This Arm is investigating the safety and effectiveness of gene therapy in people with hemophilia. Etranacogene dezaparvovec (HEMGENIX®) Module This is an observational study to characterize the effectiveness and safety of HEMGENIX® in participants with hemophilia B. Congenital Platelet Disorders (CPD) Natural History Arm: The CPD Arm is investigating the natural history of the safety and efficacy of hemostatic therapies (such as platelet transfusions, desmopressin, antifibrinolytics, recombinant factor VIIa) in the prevention or treatment of bleeding events (on demand, surgery, prophylaxis) in adult and pediatric participants with inherited congenital platelet disorders.. Glanzmann Thrombasthenia (GT) Module: This Module is a study of bleeding symptoms, treatments, and treatment outcomes in patients with Glanzmann thrombasthenia. Von Willebrand Disease Cohort No arms or modules open at this time. Rare Disorders Cohort No arms or modules open at this time. Bleeding NOS No arms or modules open at this time. Thrombosis/Thrombophilia No arms or modules open at this time. Non-Neoplastic Hematologic Conditions No arms or modules open at this time.

Primary
| Measure | Time frame | Description |
|---|---|---|
| To determine the safety of therapies used in the treatment of participants with congenital or acquired non-neoplastic, bleeding and clotting disorders and connective tissue disorders with bleeding tendency (blood disorders). | 15 years | Safety will be measured by those events in the European Safety Surveillance (EUHASS)1: 1. Allergic or other acute events 2. Treatment-emergent side effects of therapy 3. Transfusion transmitted infections 4. Inhibitor development 5. Thrombosis 6. Cardiovascular events 7. Malignancies 8. Neurological events 9. Death In addition to the modified EUHASS endpoints, the following events will be collected as adverse events of special interest (AESI): 1.
