RAPPERSWIL, Switzerland, October 24, 2017 /PRNewswire/ --

The study, in contrast to previously published Grafalon® studies, did not achieve the primary endpoint in the overall population but did demonstrate a statistically significant reduction in acute GVHD II-IV as well as moderate and severe cGVHD. A post hoc analysis demonstrated a striking relationship between the underlying conditioning regimen and clinical outcomes. Additionally,
"This large and well controlled study builds on the knowledge we have in treating patients undergoing hematopoietic cell transplant," commented Robert J. Soiffer, MD, Chief, Division of Hematologic Malignancies, Co-Chief, Stem Cell Transplantation at Dana-Farber Cancer Institute, Professor of Medicine, Harvard Medical School. "This phase 3 trial represents a major advance in the research of cGVHD, a serious and life-threatening condition with significant unmet medical need."
"First and foremost, we thank the patients and clinical research teams who made this study possible. While Grafalon® is approved and used for GVHD prophylaxis in many countries, U.S patients currently don't have an FDA approved treatment option to prevent cGVHD," commented J. Frank Glavin, Vice President and Head of Neovii North America. "The study's results bring us closer to realizing our patient-driven mission to meaningfully advance the care of patients who undergo HSCT."
About the Phase 3 Study
The study was a prospective, randomized, double blind, placebo-controlled multicenter phase 3 study in North America and Australia (NCT01295710). The study enrolled 260 patients 18-65 years of age with acute leukemia or myelodysplastic syndrome undergoing myeloablative HLA-matched unrelated hematopoietic stem cell transplantation. Patients were randomized in a 1:1 double blinded fashion between ATLG given at 20 mg/kg/day IV versus placebo (250 ml of normal saline) given on days -3, -2, and -1 prior to HCT. All patients received antihistamine and IV methylprednisolone at 2 mg/kg on day -3 and 1 mg/kg on days -2 and -1. Conditioning regimens were declared prior to randomization. The primary endpoint was assessed by clinicians utilizing the 2005 NIH consensus criteria and adjudicated by an Independent Endpoint Committee.
Graft versus host disease (GVHD) is a serious, life threatening complication that can occur in patients after they receive allogeneic stem cell transplantation. It develops when the new immune system, which arises from the transplanted stem cells (graft), attacks tissues and organs of the recipient (host). Symptoms of GVHD can occur in the skin, eyes, mouth, gut, liver, and lungs. The condition is estimated to occur in 30% to 70% of all patients who receive HSCT.
Grafalon® is a rabbit anti-human T-lymphocyte immunoglobulin (ATLG), used as part of immunosuppressive regimens for the prevention of graft versus host disease in stem cell transplantation, prevention and treatment of rejection in solid organ transplantation or as immunosuppressive in the treatment of aplastic anemia (in accordance with country-specific approved indications). With more than 200,000 treated patients to date in more than 50 countries, Grafalon® enjoys worldwide recognition among solid organ and stem cell transplant teams and has transformed the way transplant teams manage the care of their patients around the world.
