Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This study evaluates the risks and experience of blood clots and bleeding in patients with blood cancers. While it is standard of care to use medications to reduce the risk of blood clots in hospitalized individuals, some patients with blood cancers have low platelet counts that can increase the concern for bleeding complications associated with these medications. At this time, the optimal management strategies for blood clots are not well known for patients with blood cancers. This pilot study evaluates additional information that could help doctors know which patients are at highest risk for blood clots.
