Acquired manufacturing and marketing approval as a recurring or refractory peripheral T cell lymphoma (PTCL) treatment drug – Novel mechanism of action, approved in Japan ahead of the worldMundipharma Co.Ltd. (Headquarters: Minato-ku, Tokyo, President and CEO: Akira Kimura, hereinafter “Mundipharma”) today announced that purine nucleosides with efficacy and effect as recurrent or refractory peripheral T cell lymphoma (PTCL) We are pleased to inform you that we have approved domestic manufacturing and marketing of phosphorylase (PNP) inhibitor “Mundecin® capsule 100 mg” (generic name: phorodecyn hydrochloride, hereinafter “Mundecin®”). Mundecin ® is the first medicine approved in Japan for the first time in the world.PTCL originates from mature T cells and natural killer (NK) cells and is a diverse group of diseases characterized by diverse organ infiltration by lymphoid tumor cells. In Japan, annual onset cases are estimated to be about 2,000 cases, accounting for 10-15% of intermediate-grade lymphoma. In addition, the good age is elderly people over 65 years old, and the older the older, the higher the incidence rate tends to be. Since CHOP therapy combining several anticancer drugs in the early 1990 became the standard primary treatment of intermediate-grade non-Hodgkin’s lymphoma there has been little progress in treatment options for PTCL. In addition, standard treatment has not been established since PTCL secondary therapy has been established, it is known to be a disease with poor prognosis.This approved Mundeshin® is a PNP inhibitor of a novel mechanism of action that has been confirmed for the first time in the world. It is thought that inhibiting PNP accumulates 2-deoxyguanosine triphosphate in cells, induces apoptosis, and suppresses proliferation of T cell-derived tumor cells. In addition, it is the first oral treatment with a therapeutic drug whose recurrence or refractory PTCL has its indication or effect, and it is expected that the burden on hospital visits to patients will be reduced and treatment at home will be possible .Kosuke Kimura, President and Representative Director of the Company, stated the manufacturing and marketing approval for this time as follows. “I am delighted to be able to offer new treatment options to patients with recurrent or refractory PTCL in Japan through Mundecin® We have been working on development aiming for early approval in Japan ahead of the world We would like to express our sincere gratitude to the Japanese patients and their families who participated in the trial and to those involved with the clinical trial facility who cooperated and we will continue to challenge for patients in Japan.The cancer area is our priority area, and by offering Mundecin®, we will contribute to satisfying patients’ treatment options. In addition, we will continue to contribute to various needs related to the health of patients and families by enriching products in the cancer area.Product overview of Mundecin®Product name: Mundecin® capsule 100 mgCommon name: Folodecin hydrochlorideDOSAGE AND ADMINISTRATION: Usually, adults are given 300 mg twice a day as foldecin once.
