Proteomics of Primary Hyperoxaluria Type 1
93 participantsStarted 2017-01-05
Plain-language summary
The purpose of this study is to identify unique urine protein markers of Primary Hyperoxaluria type 1 (PH1) compared to healthy controls. Urine protein markers can be identified by "proteomic" analyses in which proteins are processed in a lab to break them down into smaller building blocks. Using analytical chemistry techniques and specialized equipment many proteins can be identified and measured. Most proteins are found in healthy living cells while subtle changes in these proteins or the presence of different markers reflect abnormal processes and patterns of disease. When identified in disease, protein biomarkers can help to determine if a disease responds to new types of therapies. In this study, changes in urine proteomic patterns over time, their association with change in estimated (calculated) kidney filtering function, and the relative risk for progression of PH1 will be determined. Additionally, as part of the study, the investigators will measure urinary proteins and peptides that are markers of kidney tissue protection (for healthy healing of the kidneys from ongoing damage from high urine oxalate levels, oxalate crystals and stones) to establish if and when these markers are prospectively decreased in PH1 urine. Longitudinal studies of urine "proteomics" may assist in identifying the mechanisms behind PH1-related progression of kidney failure and might contribute important information towards future identification and development of effective therapies to slow or prevent kidney failure in PH1.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Have a previously collected 24 hour urine sample from the Mayo Clinic's Rare Kidney Stone Consortium (RKSC) biobank or previously stored at Lurie Children's Hospital (Chicago, IL), a portion of which has been archived (frozen) for future research because you are a patient who has been diagnosed with Primary Hyperoxaluria type 1 (PH1) that is documented by one of the following: (1) PH1 mutation confirmed and/or (2) liver biopsy confirmed; OR
* Have a previously collected 24 hour urine sample, a portion of which has been archived (frozen) for future research, because you are a healthy sibling of a PH1 patient, as described above.
Exclusion Criteria:
* Have a previously collected 24 hour urine sample because you are a hyperoxaluric patient due to other causes (including secondary hyperoxaluria);
* Have PH1 and have had a 24 hour sample collected but a portion of that specimen has not been archived (frozen) for future research;
* Do not have PH1.
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.
