Mundipharma Wins Approval for Antineoplastic Agent mundesine® as Treatment for Relapsed/Refractory Peripheral T-cell Lymphoma in Japan

March 30, 2017 - 5 minutes read
  • Japan first market to receive approval for treatment worldwide
  • First oral PNP inhibitor to be approved for treatment featuring a novel action mechanism, which provides patients with ease of administration at home and saves time and resources in hospitals
  • Provides relapsed/refractory Peripheral T-cell Lymphoma (PTCL) patients with a meaningful increase in overall survival time compared to traditional chemotherapy.

Singapore 30 March, 2017: Mundipharma today announced that mundesine®, a Purine-nucleoside phosphorylase (PNP) inhibitor, has been approved for the treatment of relapsed/refractory PTCL by the Ministry of Health, Labor and Welfare in Japan. The Minister’s decision follows successful clinical trials and makes Japan the first in the world to make mundesine® available for treatment.

PTCL is a group lymphoma that develops from mature T-cells and NK-cells, where cancerous T/NK cells can cause infiltration into various organs. mundesine® is the first PNP inhibitor to be approved for treatment featuring a novel action mechanism – by inhibiting PNP, and accumulating plasma 2’-deoxyguanosine (dGuo) in cells, it eliminates the environment necessary for T-cells to grow. Accumulated dGuo induces apoptosis (cell death), reducing the proliferation of cancerous T-cells. mundesine® is also the first single agent oral treatment for this indication.

“Our team at Mundipharma K.K. in Japan have worked hard for early approval of this treatment to give patients and medical practitioners additional support in the fight against lymphoma,” said Raman Singh, President Mundipharma Asia Pacific, Latin America, Middle East and Africa.

Mr Singh added that since the beginning of 1990s when combination chemotherapy CHOP became established as the frontline treatment regimen for intermediate grade non-Hodgkin lymphoma, little progress has been made in terms of additional treatment options. Further, there is no standard second line treatment for PTCL where the median overall survival rate among patients that relapse after chemotherapy is 6.5 months.

“We would like to express our gratitude to the patients and medical practitioners who participated in our clinical trials and enabled us to make this treatment available for the first time globally,” said Mr Singh.

“In working to ensure that patients in Japan receive access to mundesine® as early as possible, Mundipharma K.K has delivered to our patient-first vision and delivered to the standards we set ourselves. This represents another positive step forward as we strive to deliver more treatment options for cancer patients in Japan as part of our mission to address the unmet patient need in emerging markets.”
