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
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.

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).
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. The occurrence of thrombotic microangiopathies, injection site reactions and cases of potential drug-induced liver injury 2. The development of anti-drug antibodies, to be measured and confirmed, if feasible 3. Severe, unanticipated bleeding 4. Hospitalizations 5. Glomerulonephritis 6. Any arm or module-specific AESI as stated in their corresponding Safety Assessment section Additional safety events of interest may be collected.
Time frame: 15 years
To establish a platform to support study arms and modules for participants with blood disorders.
For each Arm, a brief set of data elements of interests will be developed and reported for study participants.
Time frame: 15 years
To describe medication dosing regimens in participants with blood disorders.
This objective will be evaluated by: 1. Determining the number of participants who initiate and/or switch treatment with non-factor products and participants' reasons for initiating and/or switching treatment with non-factor products 2. Determining the number of participants who do not initiate treatment with non-factor products 3. Determining the number of participants who switch between different non-factor products and the participants' reasons for switching non-factor products 4. Determining the number of participants who discontinue treatment with non-factor products and participants' reasons for discontinuing treatment with non-factor products
Time frame: 15 years
To describe real-world effectiveness of therapies used for participants with blood disorders.
1. Health care utilization as measured by number and type of visits and hospitalizations per year 2. Patient reported outcomes (PROs) as measured by the Patient Reported Outcomes Measurement Information System (PROMIS®) Profile 29/25/Parent Proxy, Global Adherence Rating (GAR) (ages 7 and older), CATCH, and EQ-5D5L
Time frame: 15 years
To grow and evolve the ATHN Transcends Biorepository for current and future research through the collection of biospecimens from participants enrolled on this protocol
All participants have the option to provide consent to have specimens stored in the ATHN Transcends Biorepository. Samples will be collected as needed, including at the Baseline Visit, Annual Visit, and at Study Exit Visit (if not collected at your Annual Visit), as funding allows.
Time frame: 15 years
To describe bleeding events, changes in overall bleeding, and annualized bleeding rate (ABR) as measured by individual bleeding components.
This objective will be calculated per ISTH Bleeding Assessment Tool (ISTH BAT), participant completed Treatment and Bleed log, and if applicable, a Pictorial Bleeding Assessment Chart (PBAC), for relevant diagnoses.
