PDSA is dedicated to enhancing the lives of patients with immune thrombocytopenia (ITP) and other platelet disorders through education, advocacy, research and support.

Patient-Centered Research Guidelines


In 2016, PDSA established Patient-Centered Research Guidelines with the goal of funding the most promising research that have the potential to raise an ITP patient’s quality of life by further understanding the pathogenesis and management of primary ITP to support development of new therapies and a cure. PDSA invites the research community to submit proposals for grants that will help us meet these goals.

Research Program: Take Action to Make a Difference

Although more is known about ITP each year and new treatments are becoming available, there are many unanswered questions. The Platelet Disorder Support Association has established a research program to support initiatives that lead to better outcomes for the people we serve.

Survey of Non-Traditional Treatments

In 2001, PDSA worked with James Bussel, M.D. of the Weill Medical Center of Cornell University to develop a survey of non-traditional treatments of ITP. Results were compiled from almost 1,000 participants.

Quality of LIfe

PDSA partnered with the biotechnology company Amgen in 2006 to design and administer a survey assessing the treatment experience and life impact of ITP. This research study led to three journal articles and a poster session at the 2008 meeting of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR).



Research Partners

PDSA meets with directors of the Food and Drug Administration, National Heart Lung and Blood Institute and the Office of Rare Diseases at the National Institutes of Health, the American Society of Hematology and the European Hematology Association to monitor the research progress on relevant studies and initiatives.

Research Findings

PDSA attends major research conferences on thrombocytopenia and monitors scientific journals to report the latest research findings in the quarterly Publication and  monthly e-News.

Clinical Trials

PDSA tracks and lists the latest Clinical Trials on ITP to assure that those who want to participate are aware of these opportunities.

ITP Natural History Study Registry

The ITP Natural History Study Registry is an international patient-consented registry of individuals with ITP. The registry aims to collect, store and retrieve data on the

natural progression of ITP, enabling collection of data on diagnosis and treatment, management of care, quality of life, clinician reporting, and characterization of the ITP population as a whole.
