Clinical Trial Summary

In parallel with the growth of American Thrombosis and Hemostasis Network's (ATHN) clinical studies, the number of new therapies for all congenital and acquired hematologic conditions, not just those for bleeding and clotting disorders, is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have yet to demonstrate 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.(1,2,3,4) In 2019 alone, the United States Food and Drug Administration (FDA) has issued approvals for twenty-four new therapies for congenital and acquired hematologic conditions.(5) In addition, almost 10,000 new studies for hematologic diseases are currently registered on www.clinicaltrials.gov.(6) With this increase in potential new therapies on the horizon, 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. ATHN Transcends is a cohort study to determine the safety, effectiveness, and practice of therapies used in the treatment of participants with congenital or acquired non-neoplastic blood disorders and connective tissue disorders with bleeding tendency. The study consists of 7 cohorts with additional study "arms" and "modules" branching off from the cohorts. The overarching objective of this longitudinal, observational study is to characterize the safety, effectiveness and practice of treatments for all people with congenital and acquired hematologic disorders in the US. 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.(7)


Description:

This is a longitudinal, natural history observational cohort study being conducted at approximately 150 ATHN-affiliated sites. Participants will be followed for a minimum of 15 years. Harmonized data elements will be collected at the time of enrollment, quarterly, annually, and ad hoc. Base data will be collected for all participants. Specific 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 may be developed to provision disease and/or disease specific insights related to stakeholders, including but not limited to pharmaceutical companies, ATHN, and Hemophilia Treatment Centers (HTCs). Arms may branch off into product-specific data collection via Modules to be collected during the study, in conjunction with planned study assessments.

Primary To determine the safety of therapies used in the treatment of participants with congenital or acquired non-neoplastic blood disorders and connective tissue disorders with bleeding tendency. Safety will be measured by those events in the European Safety Surveillance (EUHASS).
Allergic or other acute events
Treatment-emergent side effects of therapy
Transfusion transmitted infections
Inhibitor development
Thrombosis
Cardiovascular events
Malignancies
Neurological events
Death
In addition to the modified EUHASS endpoints, the following events will be collected as adverse events of special interest (AESI):
The occurrence of thrombotic microangiopathies, injection site reactions and cases of potential drug-induced liver injury
The development of anti-drug antibodies, to be measured and confirmed, if feasible
Severe, unanticipated bleeding
Hospitalizations
Glomerulonephritis
Additional safety events of interest (TBD) may be collected. These may be chosen from drug development profiles based on investigational studies, package inserts, and emerging clinical and scientific observations.
15 years
Primary To describe the safety and tolerability of efanesoctocog alfa in previously untreated patients (PUPs) with hemophilia A without a history of inhibitors. Safety and tolerability will be measured by Annualized Bleed Rate (ABR), number of doses to treat a bleed, doses during perioperative surgery, and clinical patient reported outcomes (PROs) in this population. 7 years
Secondary To establish a platform to support study Arms and Modules for participants with bleeding, clotting, other non-neoplastic blood disorders, and connective tissue disorders with bleeding tendency. For each Arm, a brief set of data elements of interests will be developed and reported for study participants. 15 years
Secondary To describe medication dosing regimens in the above conditions. This objective will be evaluated by:
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
Determining the number of participants who do not initiate treatment with non-factor products
Determining the number of participants who switch between different non-factor products and the participants' reasons for switching non-factor products
Determining the number of participants who discontinue treatment with non-factor products and participants' reasons for discontinuing treatment with non-factor products
15 years
Secondary To grow and evolve a biorepository for current and future research through the collection of biospecimens from every person enrolled on this protocol. All participants will have the option of having specimens drawn (about 5mL each) at baseline to be stored in the ATHN Research Biorepository (ARB). 15 years
Secondary To describe real-world effectiveness of therapies by evaluating for Health care utilization Measured by number and type of visits and hospitalizations per year. 15 years
Secondary 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), and if applicable, a Pictorial Bleeding Assessment Chart (PBAC), for applicable diagnoses. 15 years
