简要总结

This study aims to evaluate the safety and feasibility of administering AZA in conjunction with steroids as first line therapy for GI GVHD.

A risk for patients who have received a transplant from another donor is graft versus host disease (GVHD). This happens because of differences between the donated cells (graft) and the patient body's cells (host). The new cells from the donor might see the patients body's cells as different and attack them. GVHD can be very serious and cause death. The standard first treatment for GVHD is corticosteroids but not all patients respond and they then have to receive other treatments. In addition, when GHVD involves the gut it can damage stem cells and can cause long term gut problems such as abdominal pain bowel disturbance. In laboratory studies giving a medicine called 5 -azacytidine (AZA) has been able to protect the gut stem cells and help them recover. In this trial the investigators would like to see if AZA can do the same thing when given with steroids in patients with GVHD.

Right now, doctors and researchers don't know the best treatment for GVHD. Acute GVHD is usually treated using high-dose corticosteroids, but these don't always work well. Even if the GVHD gets better when it involves the gut there can be long term damage to gut stem cells. In the laboratory 5 azacytidine (AZA) has been able to protect gut stem cells and help them recover and the investigators would like to learn if this happens in people too.

AZA has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of patients with leukemias. It has also been used post transplant to try and risk the chance of leukemia coming back and to try and treat GVHD but AZA has not been approved by the FDA for the treatment of acute GVHD.

详细描述

Patients enrolled in this study will receive one cycle of AZA through the vein or as a shot under the skin daily for 5 days. This will start at the same time or within 3 days of starting standard treatment for gut GVHD with steroids

Medical tests before treatment--

Before being treated, patient will receive a series of standard medical tests:

  • History and Physical exam
  • Blood tests to measure blood cells, kidney and liver function
  • A biopsy of the gut to look for GVHD is possible
  • Serum pregnancy test for female patients who are of child bearing potential
  • GVHD prophylaxis (prevention) medication
  • Corticosteroid treatment
  • An optional stool research sample

Medical tests during and after treatment--

入选标准

  • Patients 12 years of age or older at time of enrollment.
  • Patients experiencing their initial presentation of stage 1 or greater acute LGI GVHD requiring systemic therapy after allogeneic transplant for any malignant or non-malignant indication using any graft/donor source or conditioning intensity.
  • Patients can be enrolled with only a clinically established diagnosis. Biopsy of involved organs with acute GVHD is encouraged but is not required and should not delay study entry.
  • Patients should not have received systemic immune suppressive therapy for treatment of active GVHD except for a maximum of 72 hours of steroid therapy prior to enrollment. Topical skin and GI corticosteroids (such as budesonide and oral beclomethasone diproprionate) are allowed.
  • Informed Consent explained to, understood by and signed by patient/guardian. Patient/guardian given copy of informed consent.

排除标准

  • Relapsed, progressing or persistent malignancy or evidence of minimal residual disease (MRD) requiring withdrawal of systemic immune suppression.
  • Patients with acute GVHD developing after administration of a donor lymphocyte infusion (DLI) for relapse / progression of disease. Patients with acute GVHD after planned donor lymphocyte infusion or planned T cell or NK cell add back are eligible.
  • 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
  • Patients receiving other drugs for the treatment of GVHD. Note, GVHD prophylaxis agents (e.g., calcineurin inhibitors) may be continued at local Investigator's discretion.
  • Patients on renal replacement therapy.
  • Patients requiring continuous supplemental oxygen (O2 requirement >2L/min to maintain peripheral O2 saturation [SpO2] >90%).
  • Patients with active hepatic sinusoidal obstructive syndrome (SOS) and/or clinical evidence of impaired hepatic function (ascites or encephalopathy related to liver disease)
  • Abnormal coagulation parameters (PT > 15 seconds, PTT > 40 seconds, and/or INR >1.5)
  • Significant active cardiac disease within the previous 6 months including:
  • NYHA class 4 CHF Unstable angina Myocardial infarction
  • Known or suspected hypersensitivity to azacytidine.
  • Platelets <20 and or absolute neutrophil count (ANC) < 1000.

研究组 & 干预措施

Treatment

Experimental

Patients will receive one cycle of AZA through the vein or as a shot under the skin daily for 5 days. This will start at the same time or within 3 days of starting standard treatment for gut GVHD with steroids.

干预措施: 5-Azacytidine (Drug)

结局指标

主要结局

Feasibility rate

时间窗: 30 days after first dose of AZA

The proportion of patients who can tolerate and complete one cycle of AZA (5-day) in combination with steroid among patients who are eligible and receive at least one dose of AZA.

Treatment-related adverse event (tAE) rate

时间窗: 30 days after first dose of AZA

The proportion of patients who develop any Grade 3-5 adverse events (per Common Terminology Criteria for Adverse Events \[CTCAE\] Version 5.0) that are considered probably, or definitely related to AZA or AZA in combination with steroid that occur in the first cycle of combination therapy until 30 days after first dose of AZA.

次要结局

  • Overall survival (OS)(6 months and 12 months after combination therapy initiation)
  • GVHD response rate(Day 28)
  • Progression-free survival (PFS)(6 months and 12 months after combination therapy initiation)
  • Systemic Infections(30 days after last dose of AZA)
