Novel First-line Therapies for Grade II Acute GVHD(Graft-versus-host Disease )

The purpose of this study is to determine the efficacy and safety of combined Ruxolitinib With Corticosteroids as First Line Therapy for grade II acute GVHD (graft-versus-host disease )

Trial of 2 Step ATG for Acute GVHD Prevention Post Myeloablative Allogeneic Stem Cell Transplant

The purpose of this study is to test whether the combination of the drugs called tacrolimus (Tac), methotrexate (MTX) and new dosing strategy of another drug called (rabbit Anti-thymocyte Globulin \[ATG\]) will help prevent the development and/or improve severity of acute and/or chronic GVHD.

CXCL9 and EASIX for Prediction of Acute Graft Versus Host Disease

The prediction of severe acute GVHD before it occurs is of high importance for ensuing clinical decisions and overall success of allogeneic SCT. The key immunologic signatures associated with clinical outcomes after different graft versus host disease prophylaxis methods or peripheral blood stem cell transplant are largely unknown.

Prevention of GvHD in Participants With Hematological Malignancies Undergoing Hematopoietic Stem Cell Transplant (HSCT)

The purpose of this Phase 1, first in human open-label study is to assess the safety and tolerability of TRX-103 in patients with hematological malignancies undergoing HLA-mismatched related or unrelated hematopoietic stem cell transplantation (HSCT). It is anticipated that up to 36 Subjects will be enrolled during a 18-24 month enrollment period. TRX-103 will be infused one time post HSCT.

Wharton Jelly Mesenchymal Stromal Cells as GVHD Prophylaxis

Despite progress in chemotherapy, targeted therapy and immunotherapy, allogeneic hematopoietic stem cell transplantation (allo-SCT) is still the only curative procedure for some hematological malignancies. The probability of finding a matched sibling donor (MSD) is estimated under the classical 30%, because of the age of patients and their relatives, and a matched unrelated donor (MUD) can take time to identify. Currently in France, 25% of the allo-SCT are performed with an haplo-identical related donor. The Baltimore group developed an approach using haploidentical related donors, RIC, T-replete bone marrow and post-transplant high dose cyclophosphamide (PTCy) in patients with advanced hematological malignancies. PTCy has shown to eradicate alloreactive donor and host T-cells, activated by respective antigens, thereby reducing the incidence of graft versus host disease (GvHD) but delaying hematopoietic recovery. Therefore, the main source of graft is peripheral blood stem cells (PBSC) mobilized by G-CSF in France. Unfortunately, with PBSC we observe a higher cumulative incidence of GvHD (around 50%) and a higher toxicity-related mortality (TRM), especially for recipients \>50 years old. The co-transplantation of Mesenchymal Stem Cells (MSC) at the time of transplantation has previously shown a double interest in GvHD immunomodulation and hematopoiesis support. Pre-clinical studies (in mice) have shown that mesenchymal stromal cells (MSCs) from Wharton's Jelly reduce the incidence of GvHD when the infusions are weekly repeated. We propose a phase I clinical trial to find the maximum tolerated dose (MTD) of a weekly infusion of WJ-MSC administered as GvHD prophylaxis and as a support for a faster hematological reconstitution after haplo-identical allo-SCT.
