NCT04567511

Brief Summary

This is a single arm, phase 4, prospective, open-label, United States single-center study to determine the hemostatic characteristics of Hemlibra (emicizumab) as measured by coagulation laboratory parameters in the mild hemophilia A male patient population with endogenous altered FVIII (baseline FVIII activity of \>5% to 30%). The safety and hemostatic efficacy of Hemlibra (emicizumab) in this patient population will be investigated. Secondary outcomes will assess changes in joint health and quality of life in treated patients.

Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Signed informed consent form from the subject, parent or guardian

Data Sharing

IPD Sharing
Will share

The investigators will share resources and data from this project through collaborative publications in the scientific literature as well as through national, regional and international conference presentations. The investigators will also share our methods and findings in a prompt manner with regional, national and international stakeholders to ensure that findings will be readily available to other researchers and clinicians with clinical or scientific interest in the subject area. Individual participant data that underlie the results reports in publications, reports or presentations (including text, tables, figures and appendices) will be shared after de-identification.

Shared Documents
STUDY PROTOCOL, SAP, CSR
Time Frame
IPD and additional information on study methods will be made available starting 9 months after publication or conclusion of the study and ending 36 months following publication or study conclusion.
Access Criteria
IPD and study information will be shared with investigators whose proposed use of the data has been approved by an independent review committee ("learned intermediary"), whose proposals are methodologically sound, and for purposes that are consistent with the aims of the underlying research. Proposals will be reviewed by the Principle Investigator, Dr. Amy Shapiro, and may be submitted to ashapiro@ihtc.org. Requestors will be required to sign a data access and use agreement.
