Clinical and Basic Investigations Into Hermansky-Pudlak Syndrome
United States600 participantsStarted 1995-11-06
Plain-language summary
Hermansky-Pudlak Syndrome (HPS) is an inherited disease which results in decreased pigmentation (oculocutaneous albinism), bleeding problems due to a platelet abnormality (platelet storage pool defect), and storage of an abnormal fat-protein compound (lysosomal accumulation of ceroid lipofuscin).
The disease can cause poor functioning of the lungs, intestine, kidneys, or heart. The major complication of the disease is pulmonary fibrosis and typically causes death in patients ages 40 - 50 years old. The disorder is common in Puerto Rico, where many of the clinical research studies on the disease have been conducted. Neither the full extent of the disease nor the basic cause of the disease is known. There is no known treatment for HPS.
The purpose of this study is to perform research into the medical complications of HPS and begin to understand what causes these complications. Researchers will clinically evaluate patients with HPS of all ethnic backgrounds. They will obtain cells, blood components (plasma), and urine for future studies. Genetic tests (mutation analysis) to detect HPS-causing genes will also be conducted.\<TAB\>...

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
* INCLUSION CRITERIA
Persons with HPS or family members who are their caregivers aged 1-80 years are eligible to enroll in this protocol. The diagnosis of HPS is based upon a paucity or deficiency of platelet dense bodies on whole mount electron microscopy or the identification of pathogenic variants in HPS genes by genetic testing. Some persons who have not been diagnosed with HPS may be admitted to the protocol based upon the presence of albinism and a platelet storage pool deficiency.
Subjects participating only in the HPS Symptom Questionnaire will be at least 18 years of age.
EXCLUSION CRITERIA
Pregnant women and adults who are unable to provide consent are excluded.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
