"The significantly improved composite endpoint 'Severe GvHD free and relapse free survival' clearly indicates the impact of ATLG in the cure of patients without ongoing morbidity, which is the main aim of allogeneic stem cell transplantation. This is supported by the fact that the vast majority of patients alive after ATLG-containing GvHD prophylaxis are free of immunosuppressive therapy," said Professor Jrgen Finke, the principal investigator of the study and Deputy Head of the Department of Hematology and Oncology at the Faculty of Medicine and Medical Center at the University of Freiburg, Germany. Professor Finke is also Chairman of the German Stem Cell Transplant Working Group (DAG-KBT). He added, "The results clearly demonstrate the importance of ATLG administration in matched unrelated stem cell transplantation and will certainly influence decision-making and patient counselling in the long run."

Alexandre Sudarskis, CEO of Neovii, commented, "These ground-breaking results undoubtedly prove the long-term efficacy of Grafalon administration as part of a myeloablative conditioning regimen." He added, "Neovii strives to better meet the needs of our patients and to improve their quality-of-life with our effective antibody therapies, allowing physicians to apply a safe and robust therapy." Neovii supports research and development activities in the fields of stem cell transplantation, solid organ transplantation, and immune and hemato-oncological disorders.

About the study

Prospective, multicenter, open-label, randomized, phase 3 study of Grafalon comparing standard ciclosporin A and methotrexate containing GvHD prophylaxis. Patients were randomized to either receive or not receive Grafalon. The study was conducted in 9 European countries and Israel in 31 study centers, enrolling 202 patients. Patients had acute leukemia or myelodysplastic syndrome or myeloproliferative disease in an early (n=107) or advanced disease status (n=94). After myeloablative conditioning, patients received transplantation of blood stem cells (n=164) or bone marrow grafts (n=37). Study results were published in 2009[2] and 2011[3].

About GvHD

Graft versus host disease (GvHD) is a serious, life threatening complication after 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). It can be classified as acute or chronic, depending on the time of occurrence and/or the pathology.

About Grafalon

Grafalon (formerly commercialized as ATG Fresenius), is a rabbit anti-human T-lymphocyte immunoglobulin, 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 (according to 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.
