This study is designed as a combined Phase II/III, randomized, open label, multicenter, prospective comparative study of sirolimus plus prednisone, sirolimus/extracorporeal photopheresis plus prednisone versus sirolimus/calcineurin-inhibitor plus prednisone for the treatment of chronic GVHD. Patients will be stratified by transplant center and will be randomized to one of the two pre-specified experimental arms (Sirolimus + prednisone, Sirolimus + ECP + prednisone) or the comparator arm (Sirolimus + calcineurin inhibitor + prednisone) in a 1:1 ratio.
Background: Chronic GVHD is a medical condition that can become very serious. Chronic GVHD is a common development after allogeneic transplant that occurs when the donor cells attack and damage tissues. The primary purpose of this study is to compare treatment regimens that contain sirolimus without a calcineurin inhibitor to a comparator regimen of sirolimus with a calcineurin inhibitor and evaluate how well chronic GVHD responds to treatment. The combinations of medications in this study are:
- Sirolimus + calcineurin inhibitor + prednisone
- Sirolimus + prednisone
- Sirolimus + extracorporeal photopheresis + prednisone
The goal is to select a treatment regimen for further comparison in the Phase III trial.
Design Narrative: The intent is to enroll subjects at the start of their initial therapy for high-risk chronic GVHD, or before their standard-risk chronic GVHD is refractory to glucocorticoid therapy, or is chronically dependent upon glucocorticoid therapy and multiple secondary systemic immunosuppressive agents. Patients will be stratified by transplant center and will be randomized to one of the three arms.
Only one of the two Phase II studies above will proceed into the Phase III component of the study.

This study will evaluate whether conversion from cyclosporine, a calcineurin inhibitor (CI) to sirolimus (SRL) results in improved long-term renal function without a negative impact on saf...
This study evaluates two different immunosuppression drug regimens in patients with a recent kidney transplant. Patients initially received a regimen of Sirolimus, Tacrolimus and Predniso...
Small studies have reported superiority of sirolimus (SRL) over calcineurin inhibitor (CNI) in mitigating cardiac allograft vasculopathy (CAV) after heart transplantation (HT). However, data on the lo...
Therapeutic drug monitoring (TDM) of sirolimus is essential in transplant recipients. We evaluated the performance of a new electrochemiluminescence immunoassay (ECLIA) for measuring sirolimus concent...

A macrolide compound obtained from Streptomyces hygroscopicus that acts by selectively blocking the transcriptional activation of cytokines thereby inhibiting cytokine production. It is bioactive only when bound to IMMUNOPHILINS. Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties.
A derivative of sirolimus and an inhibitor of TOR SERINE-THREONINE KINASES. It is used to prevent GRAFT REJECTION in heart and kidney transplant patients by blocking cell proliferation signals. It is also an ANTINEOPLASTIC AGENT.
A family of immunophilin proteins that bind to the immunosuppressive drugs TACROLIMUS (also known as FK506) and SIROLIMUS. EC 5.2.1.-
A 12-KDa tacrolimus binding protein that is found associated with and may modulate the function of calcium release channels. It is a peptidyl-prolyl cis/trans isomerase which is inhibited by both tacrolimus (commonly called FK506) and SIROLIMUS.
Members of a family of highly conserved proteins which are all cis-trans peptidyl-prolyl isomerases (PEPTIDYLPROLYL ISOMERASE). They bind the immunosuppressant drugs CYCLOSPORINE; TACROLIMUS and SIROLIMUS. They possess rotamase activity, which is inhibited by the immunosuppressant drugs that bind to them.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
