YSPSL for Prevention of Delayed Graft Function Part B
A Phase 1/2 study testing YSPSL in people with Kidney Diseases, run by Y's Therapeutics, Inc. at 15 sites in United States.
Trial summary
Selectins have been implicated in the pathogenesis of ischemia/reperfusion (I/R)-induced kidney injury and resultant delayed graft function (DGF). PSGL-1 is a ligand for P-, E-, and L-selectin. It has been reported that YSPSL (rPSGL-Ig) blocks P-selectin and, to a lesser degree, E- and L-selectin. Read more about this study

About this study
Official title: Controlled, Randomized, Prospective, Double-Blind, Multicenter, Phase I/II, Dose-Escalation Study of the Safety, PK, and Efficacy of YSPSL for Prevention of Delayed Graft Function in Patients Undergoing Cadaveric Kidney Transplantation
Selectins have been implicated in the pathogenesis of ischemia/reperfusion (I/R)-induced kidney injury and resultant delayed graft function (DGF). PSGL-1 is a ligand for P-, E-, and L-selectin. It has been reported that YSPSL (rPSGL-Ig) blocks P-selectin and, to a lesser degree, E- and L-selectin. Both sPSGL-1 and YSPSL (rPSGL-Ig) have been shown in animal models to reduce both cytokines and tissue damage associated with ischemia reperfusion and to improve renal function post-transplant. Therefore, the current phase I/II clinical study is designed to assess the safety and efficacy of YSPSL (rPSGL-Ig) in preventing DGF in patients undergoing cadaveric kidney transplants and to determine a dose for future pivotal studies.
Read the detailed description
This will be a multicenter, single-dose, dose-escalation study. The study will be in 2 parts: the first, Part A, will be an open label evaluation of single doses of four dose cohorts; the second, Part B will be a randomized, double-blind, placebo-controlled, single-dose study of two dose cohorts. Patients who are undergoing cadaveric kidney transplantation and are at risk for development of DGF, based upon known risk factors, will be eligible to participate in the study. A maximum of 24 patients will be enrolled in Part A. 60 patients will be enrolled in Part B.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing YSPSL in people with Kidney Diseases, run by Y's Therapeutics, Inc. at 15 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Jan 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 15 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
delayed graft function post transplant (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00298168, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2008; AzTrials last refreshed its copy on 6 Nov 2026.
