Inclusion Criteria

Inclusion Criteria:<br><br>To be eligible to participate in this study, patients must meet the following:<br><br> 1. Patients must be at least 18.0 years of age at the time of consent.<br><br> 2. Patient has undergone first allo-HSCT from any donor source or graft source.<br> Recipients of nonmyeloablative, reduced intensity, and myeloablative conditioning<br> regimens are eligible.<br><br> 3. Patients diagnosed with Grade III/IV SR-aGVHD after allo-HSCT. SR includes aGVHD<br> initially treated at a lower steroid dose, but must meet one of the following<br> criteria:<br><br> - Progressed or new organ involvement after 3 days of treatment with<br> methylprednisolone (or equivalent) of greater than or equal to 2 mg/kg/day<br><br> - No improvement after 7 days of primary treatment with methylprednisolone (or<br> equivalent) of greater than or equal to 2mg/kg/day<br><br> - Patients with visceral (GI and/or liver) plus skin aGVHD at methylprednisolone<br> (or equivalent) initiation with improvement in skin GVHD without any<br> improvement in visceral GVHD after 7 days of primary treatment with<br> methylprednisolone (or equivalent) of greater than or equal to 2mg/kg/day<br><br> - Patients who have skin GVHD alone and develop visceral aGVHD during treatment<br> with methylprednisolone (or equivalent) of greater than or equal to 1mg/kg/day<br> and do not improve after 3 days of greater than or equal to 2mg/kg/day<br> Improvement or progression in organs is determined by comparing current organ<br> staging to staging at initiation of methylprednisolone (or equivalent)<br> treatment.<br><br> 4. Patients must have evidence of myeloid engraftment (e.g., absolute neutrophil count<br> greater than or equal to 0.5 × 109/L for 3 consecutive days if ablative therapy was<br> previously used). Use of growth factor supplementation is allowed.<br><br> 5. Patients or an impartial witness (in case the patient is capable of providing verbal<br> consent but not capable of signing the informed consent form (ICF)) should have<br> given written informed consent.<br><br>Exclusion Criteria:<br><br>Patients will be excluded from study entry if they meet any of the following exclusion<br>criteria:<br><br> 1. Patients who have a creatinine greater than or equal to 2mg/dL or estimated<br> creatinine clearance less than 40 mL/min or those requiring hemodialysis.<br><br> 2. Patients who have been diagnosed with active thrombotic microangiopathy (TMA),<br> defined as meeting all the following criteria:<br><br> - Greater than 4% schistocytes in blood (or equivalent if semiquantitative scale<br> is used e.g., 3+ or 4+ schistocytes on peripheral blood smear)<br><br> - De novo, prolonged or progressive thrombocytopenia (platelet count less than 50<br> x 109/L or 50% or greater reduction from previous counts)<br><br> - Sudden and persistent increase in lactate dehydrogenase concentration greater<br> than 2x the upper level of normal (ULN)<br><br> - Decrease in hemoglobin concentration or increased transfusion requirement<br> attributed to Coombs-negative hemolysis<br><br> - Decrease in serum haptoglobin<br><br> 3. Patients who have previously received treatment with eculizumab.<br><br> 4. Patients who have previously received checkpoint inhibitors (either before or after<br> allo-HCT).<br><br> 5. Patients who have been diagnosed with overlap syndrome, that is, with any concurrent<br> features of cGVHD.<br><br> 6. Patients requiring mechanical ventilation or vasopressor support.<br><br> 7. Patients who have received any systemic treatment, besides steroids, as upfront<br> treatment of aGVHD or as treatment for SR-aGVHD. Reinstitution of previously used<br> GVHD prophylaxis agents (e.g., tacrolimus, cyclosporin, methotrexate [MTX], MMF) or<br> substitutes in cases with previously documented intolerance will be permitted.<br> Previous treatment with a janus kinase (JAK) inhibitor as part of GVHD prophylaxis<br> or treatment is not allowed.<br><br> 8. Patients who have severe hypoalbuminemia, with an albumin of less than or equal to 1<br> g/dl.<br><br> 9. Patients who have a creatine kinase (CK) level of greater than 5 times the upper<br> limit of normal.<br><br> 10. Patients with uncontrolled infections. Infections are considered controlled if<br> appropriate therapy has been instituted and, at the time of enrollment, no signs of<br> progression are present. Persisting fever without other signs or symptoms will not<br> be interpreted as progressing infection. Progression of infection is defined as:<br><br> - hemodynamic instability attributable to sepsis OR<br><br> - new symptoms attributable to infection OR<br><br> - worsening physical signs attributable to infection OR<br><br> - worsening radiographic findings attributable to infection Patients with<br> radiographic findings attributable to infection within 4 weeks prior to<br> enrollment must have a repeat radiographic exam within one week of enrollment<br> that documents absence of worsening.<br><br> 11. Patients with evidence of relapsed, progressing, or persistent malignancy, or who<br> have been treated for relapse after transplant, or who may require rapid immune<br> suppression withdrawal as pre-emergent treatment of early malignancy relapse.<br><br> 12. Patients with evidence of minimal residual disease requiring withdrawal of systemic<br> immune suppression.<br><br> 13. Patients with unresolved serious toxicity or complications (other than aGVHD) due to<br> previous transplant.<br><br> 14. History of sinusoidal obstruction syndrome (SOS)/veno-occlusive disease (VOD).<br><br> 15. Patients with known hypersensitivity to any of the components murine monoclonal<br> antibodies (mAb) or Recombinant Ricin Toxin A-chain (RTA).<br><br> 16. Patients who have had treatment with any other investigational agent, device, or<br> procedure within 21 days (or 5 half-lives, whichever is greater) prior to<br> enrollment. An investigational agent is defined as medications without any known FDA<br> or European Medicines Agency (EMA) approved indications.<br><br> 17. Patients who have received more than one allo-HSCT.<br><br> 18. Patients with known human immunodeficiency virus infection.<br><br> 19. Patients who have a BMI greater than or equal to 35 kg/m2.<br><br> 20. Patients who are taking sirolimus must discontinue prior to starting study<br> treatment.<br><br> The sirolimus blood level must be less than 2 ng/mL prior to starting study<br> treatment.<br><br> 21. Female patients who are pregnant, breast feeding, or, if sexually active and of<br> childbearing potential, unwilling to use effective birth control from start of<br> treatment until 30 days after the last study treatment.<br><br> 22. Male patients who are, if sexually active and with a female partner of childbearing<br> potential, unwilling to use effective birth control from start of treatment until 65<br> days after the last study treatment.<br><br> 23. Patients with any condition that would, in the investigator's judgment, interfere<br> with full participation in the study, including administration of study drug and<br> attending required study visits; pose a significant risk to the patient; or<br> interfere with interpretation of study data.<br><br> 24. Patients whose decision to participate might be unduly influenced by perceived<br> expectation of gain or harm by participation, such as patients in detention due to<br>
