Clinical Trial Summary

Many risk factors are known to be associated with high risk of developing CMV infection in positive CMV-serostatus patients: negative CMV-serostatus donor, unrelated or mismatched donor, use of antithymocyte globulin (ATG), and development of GVHD. Acute GVHD occurs during the first hundred days after transplantation. In spite of systematic GVHD prophylactic using immunosuppressive agents, approximately 50% of transplantation recipients develop GVHD. The first-line treatment of acute GVHD is methylprednisolone 2 mg/kg/day. Probably because of the use corticosteroids but also due to the GVHD itself, approximately 46% of CMV seropositive patients develop CMV infection (report from the national database of the SFGM-TC, data unpublished yet). CMV infection leads to longer duration of hospitalization and increases the risk of mortality, particularly in cases of CMV disease. Available antiviral agents used to prevent CMV infections are generally reputed to cause significant side effects. These agents can prevent full immunological post-transplant reconstitution and cause profound cytopenia. Some agents may be responsible for renal impairment, which prevents continuation of immunosuppressive treatment; this is especially the case with calcineurin inhibitors in allo-HCT patients. Indeed, compared to placebo, intravenous ganciclovir has been shown to reduce the risk of CMV infection and disease, although it did not appear to improve overall survival. However, it was responsible for 30% of cases of severe neutropenia in allo-HCT patients, increasing the risk of bacterial and fungal coinfections. CMV infection treatment is commonly based on ganciclovir and foscavir and, to a lesser extent, on other drugs, including cidofovir. However, these drugs cause high levels of toxicity, resulting in myelotoxicity in the case of ganciclovir, or, in the case of foscavir and cidofovir, potential renal failure, incurring treatment discontinuation. CMV prophylaxis using drugs with fewer side-effects is necessary in patients at high risk of CMV infection. With its safety profile, Cytotect®CP offers an alternative option for CMV prophylaxis with avoidance of renal and bone marrow impairment. Considering the high risk of developing CMV infection, we decided to investigate the efficacy and safety of Cytotect®CP in patients requiring systematic corticosteroids (≥ 1 mg/kg/day) for an initial episode of grade II-IV acute GVHD following a first allo-HCT.
