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.

The James B. Bussel, MD, ITP Young Investigator Award

Dr. James BusselThe James B. Bussel, MD ITP Young Investigator Award was established in 2017 by the PDSA Board of Directors to honor Dr. Bussel for all that he has done and continues to do to make a difference in the lives of ITP patients, their families, and his contributions to mentoring and advancing the scientific careers of promising clinical investigators.

Fellow PDSA medical advisor Doug Cines, MD, said Dr. Bussel “was a pioneer, not only of research in ITP, but for a generation of trainees who could follow his experience. His career shows that is possible to succeed scientifically and academically as a clinically oriented investigator even in rare diseases like ITP if you are persistent and have a creative mind. There are many young investigators and countless patients with ITP who have not met Jim personally and have no idea how much they owe to his contributions to research and patient care.”

The James B. Bussel, MD, ITP Young Investigator Award is competitively awarded to support excellence in academic ITP research by providing a selected student deemed to be of exceptional promise and a highly meritorious project with a $2,500.00 scholarship award funded by the Platelet Disorder Support Association.

Applications for the 2019 award are no longer being accepted.  Submission dates for the 2020 award will be posted here.



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 (ITP-PAQ) 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).

ITP Patient Assessment Questionnaire (ITP-PAQ)

PDSA’s exclusive ITP-PAQ is a fundamental research instrument designed to measure quality of life issues of patients with immune thrombocytopenia. Clinical or biological measures of the disease often include factors that simply describe a patient’s health in terms of what health professionals or society believe constitutes quality of life. The ITP-PAQ measures quality of life factors important to patients. An essential tool used to supplement objective clinical or biological measures of disease, this patient-centered instrument effectively captures patients' perspectives of their disease and treatment, its impact on daily life, their perceived need for health care, and feelings about treatment and outcomes.

Amgen has the exclusive copyright to the ITP-PAQ, but has granted PDSA license to sublease the Agreement.

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.
