Four Independent Studies of Voraxaze® Published at European Hematology Conference 2022

Vienna, June 09, 2022 (GLOBE NEWSWIRE) -- The European Hematology Association (EHA) Conference published four independent studies of Voraxaze® (glucarpidase) by various investigators for inclusion in its June 2022 EHA Hybrid Congress abstract book and for publication in HemaSphere, EHA’s peer-reviewed, open access journal.

All four abstracts are the result of independent studies in Europe and the United States; three explore whether routinely giving Voraxaze® in combination with high-dose methotrexate (“planned use”) might alleviate toxicity, manage the risk to patients and help them to complete therapy.

  • PLANNED-USE GLUCARPIDASE FOR OUTPATIENT HIGH DOSE METHOTREXATE (HD-MTX) ADMINISTRATION IN PATIENTS WITH CNS LYMPHOMA (CNSL) DURING THE COVID-19 PANDEMIC, by Lauren Schaff, Mina Lobbous, Dean Carlow, Lisa DeAngelis, Louis Burt Nabors, and Christian Grommes, demonstrates the feasibility of planned-use Voraxaze to facilitate the outpatient administration of HD-MTX for patients with CNS lymphoma. Twenty outpatient treatments of HD-MTX with glucarpidase were administered to a total of 7 patients. Some grade 1 and grade 2 adverse events attributable or possible attributable to Voraxaze were noted. None of the patients required hospital admission during treatment. [Link to abstract]

  • REDUCTION OF METHOTREXATE (MTX) LEVELS AFTER GLUCARPIDASE IN PATIENTS WITH DIFFUSE LARGE B-CELL LYMPHOMA (DLBCL) AT RISK OF CENTRAL NERVOUS SYSTEM (CNS) INVOLVEMENT WHO RECEIVE HD-MTX: PHASE 2 by Adolfo De La Fuente, Francisco Javier Peñalver, Pilar Herrera, Raul Cordoba, Carmen Martinez Chamorro, Maria Teresa Olave, Isidro Jarque, and Mónica Estévez, is an open-label, interventional, non-randomized, phase 2 pilot multicenter study in diffuse large B-cell lymphoma patients at high risk of CNS relapse to assess prophylactic effect of glucarpidase in MTX related-toxicity administered after 12 hours of HD-MTX. The study aims to describe the reduction of MTX levels after systematic administration of glucarpidase 12 hours following start of HDMTX infusion in DLBCL patients at high risk for CNS involvement. This trial has not been completed. [Link to abstract]

  • INTENDED USE OF GLUCARPIDASE IN PATIENTS WITH CENTRAL NERVOUS SYSTEM LYMPHOMA AND IMPAIRED RENAL FUNCTION – THE VALIDATE STUDY by Sven Liebig, Susen Burock, Immanuel Merz, Franz Knörnschild, Peggy Kießling, Kai Kappert, Ulrich Keller, and Stefan Schwartz evaluates the safety as well as pharmacological efficacy of intended and repeated use of glucarpidase following HD-MTX in patients with CNSL and impaired renal function. Glucarpidase administration resulted in a rapid and pronounced reduction of MTX blood levels (> 97%) within 15 minutes and in all 12 treatment cycles for four patients, demonstrating that treatment with HD-MTX and glucarpidase is feasible in patients with CNSL and impaired renal function.
