An observational study in Hemophilia A, sponsored by Bayer. Completed at 8 sites in 7 countries. Per ClinicalTrials.gov, last updated 2025-06-15.
Sponsored by Bayer · Observational
In this study researcher want to learn more about the change of physical activity of hemophilia A patients treated with damoctocog alfa pegol. Patients enrolled in this study will be wearing a small device measuring daily active time. Researcher will compare these physical activity data with patient's clinical data including bleeding events to gain information on how bleeding levels are related to the activity level of the patients.
The study aims to enroll about 80 patients who are at the same time also participating in the HEM-POWR study (NCT03932201) evaluating the effectiveness and safety of damoctocog alfa pegol.
The primary objective is to evaluate the change in physical non-sedentary activity as measured by the ActiGraph CentrePoint Insight Watch (ActiGraph LLC, Pensacola, Florida) after 1, 2 and 3 years of treatment with damoctocog alfa pegol.
Secondary objectives are to determine the

Plan to share: No — Availability of this study's data will later be determined according to Bayer's commitment to the EFPIA/PhRMA "Principles for responsible clinical trial data sharing". This pertains to scope, timepoint and process of data access. As such, Bayer commits to sharing upon request from qualified researchers patient-level clinical trial data, study-level clinical trial data, and protocols from clinical trials in patients for medicines and indications approved in the US and EU as necessary for conducting legitimate research. This applies to data on new medicines and indications that have been approved by the EU and US regulatory agencies on or after January 01, 2014. Interested researchers can use www.vivli.org to request access to anonymized patient-level data and supporting documents from clinical studies to conduct research.
