Overview
Brief Summary
The study is a Phase II randomized, open label, multicenter trial designed to identify whether sirolimus is a potential alternative to prednisone as an up-front treatment for patients with standard-risk acute GVHD defined according to clinical and biomarker-based risk stratification. This trial incorporates both a novel up front GVHD therapy (sirolimus) as well as a novel BMT CTN developed acute GVHD biomarker test.
Detailed Description
The study is a Phase II randomized, open label, multicenter trial designed to identify whether sirolimus is a potential alternative to prednisone as an up-front treatment for patients with standard-risk acute GVHD defined according to clinical and biomarker-based risk stratification. Patients with previously untreated, standard-risk acute GVHD, according to the refined Minnesota Criteria, who are in need of systemic therapy, will have a 5 mL blood sample collected prior to randomization to assess their biomarker Ann Arbor Risk status. Ann Arbor scoring results will be provided 48-72 hours after randomization. Patients will begin their study treatment assignments within 24 hours of randomization. Those with biomarker results of combined AA1/2 risk will continue on their randomized study treatment and will be included for primary endpoint analysis (Day 28 complete or partial response) and all planned study procedures and assessments. In contrast, patients with AA3 biomarker risk and those patients with missing biomarker results may continue on their randomized therapies or start another therapy at their physicians' discretion. In addition, AA3 risk patients and those with missing results will not be considered in primary endpoint analysis, but will be included in a subset analysis.

Eligibility Criteria
Inclusion Criteria
- •Patients with standard-risk acute GVHD, according to refined Minnesota Criteria. Refined Minnesota Criteria are available at https://redcap.ahc.umn.edu/surveys/?s=bNmFhseJIf.
- •Standard-risk acute GVHD according to the refined Minnesota Risk Criteria requires meeting one of the criteria below:
- •Single organ involvement (Stage 1-3 skin, Stage 1 upper GI, or Stage 1-2 lower GI)
- •Multiple organ involvement (Stage 1-3 skin plus stage 1 upper GI, Stage 1-3 skin plus stage 1 lower GI, Stage 1-3 skin plus stage 1 lower GI plus stage 1 upper GI, Stage 1-3 skin plus stage 1-4 liver, or Stage 1 lower GI plus stage 1 upper GI)
- •Acute Minnesota Standard Risk GVHD requiring systemic immune suppressive therapy.
- •Acute GVHD developing after allogeneic hematopoietic cell transplantation using either bone marrow, peripheral blood, or umbilical cord blood. Recipients of non-myeloablative, reduced intensity conditioning and myeloablative transplants are eligible. All allogeneic donor sources are permitted, including siblings, unrelated donors, human leukocyte antigen (HLA)-haploidentical related donors and umbilical cord blood.
- •Patients NOT receiving systemic immune suppressive therapy for treatment of active GVHD (topical skin and GI corticosteroids are allowed).
- •Ability to tolerate oral or enterically-administered medications.
- •Patients of all ages.
- •Absolute neutrophil count (ANC) greater than 500/µL.
Exclusion Criteria
- •Patients receiving sirolimus (for any indication including GVHD prophylaxis) within 14 days of screening for enrollment.
- •Relapsed, progressing or persistent malignancy requiring withdrawal of systemic immune suppression.
- •Patients with acute GVHD developing after a donor lymphocyte infusion.
- •Active or recent (within 7 days) episode of transplant associated microangiopathy.
- •Patients with uncontrolled infections will be excluded. Infections are considered controlled if appropriate therapy has been instituted and, at the time of enrollment, no signs of progression are present. Progression of infection is defined as hemodynamic instability attributable to sepsis, new symptoms, worsening physical signs or radiographic findings attributable to infection. Persisting fever without other signs or symptoms will not be interpreted as progressing infection.
- •Patients unlikely to be available for evaluation at the transplant center on Day 28 and 56 of therapy.
- •A clinical presentation resembling de novo chronic GVHD or overlap syndrome developing before or present at the time of enrollment.
- •Patients receiving corticosteroids for any indication within 7 days before the onset of acute GVHD, except the following: Stable replacement doses of corticosteroids for adrenal insufficiency are permitted (e.g. hydrocortisone total dose of 10-12 mg/m\^2/day or prednisone 5-7.5mg daily or equivalent). Corticosteroids administered as premedication before transfusion of blood products or before intravenous medications to prevent infusion reactions are allowed.
- •Patients who are pregnant or breastfeeding.
- •Females of childbearing potential (FCBP) or a man who has sexual contact with a FCBP and is unwilling to use effective birth control for the duration of the study.
Arms & Interventions
Sirolimus
Sirolimus, a steroid-free therapy, will be administered after a diagnosis of standard-risk aGVHD is clinically established.
Intervention: Sirolimus
Prednisone
Prednisone, standard of care therapy for GVHD, will be administered after a diagnosis of standard-risk aGVHD is clinically established.
Intervention: Prednisone
Outcomes
Primary Outcomes
Percentage of Participants With Complete or Partial Response (CR/PR) to Acute GVHD Treatment
Time Frame: Days 28 and 56 Post-randomization
Scoring of CR/PR is in comparison to the participant's acute GVHD status at randomization. Complete response (CR) is defined as staging of 0 for in all target organs for GVHD - skin, GI tract, and liver. Partial response (PR) is defined as improvement in some target organ(s) without worsening in others. Death and initiation of systemic acute GVHD treatment beyond randomized treatment are considered failures for this endpoint. Organ staging is defined below: Skin stage: 0: No rash 1. Rash \<25% of body surface area (BSA) 2. Rash on 25-50% of BSA 3. Rash on \>50% of BSA 4. Generalized erythroderma with bullous formation Liver stage (based on bilirubin level): 0: \<2 mg/dL 1. 2-3 mg/dL 2. 3.01-6 mg/dL 3. 6.01-15.0 mg/dL 4. \>15 mg/dL GI stage: 0: No diarrhea or diarrhea \<500 mL/day 1. Diarrhea 500-999 mL/day or persistent nausea with histologic evidence of GVHD 2. Diarrhea 1000-1499 mL/day 3. Diarrhea \>1500 mL/day 4. Severe abdominal pain with or without ileus
