CAMBRIDGE, UK: 1 March 2019 – Napp Pharmaceuticals Limited today announced the UK launch of Pelmeg®, a biosimilar of pegfilgrastim, following European Commission (EC) approval in November 2018.1 Pelmeg® is indicated for the reduction in the duration of neutropenia and incidence of febrile neutropenia (FN) in adults treated with cytotoxic chemotherapy for malignancy (with the exception of chronic myeloid leukaemia and myelodysplastic syndromes).2 This is Napp’s first launch of a product developed by Cinfa Biotech, which was acquired by the Mundipharma network of independent associated companies in October 2018.3

Pelmeg® is a self-administered, single dose formulation and a lower drug cost alternative to the existing long-acting option Neulasta®2,4,5 Longer-acting alternatives can offer a less demanding treatment schedule for patients between chemotherapy cycles than the current standard of care, which requires daily injections.2,6

Although there have been improvements in the prognosis of FN, it is still responsible for considerable morbidity and mortality, with 20%-30% of patients requiring costly in hospital management and an overall mortality rate of approximately 10%.7 People who experience neutropenia and FN are at higher risk of infection, treatment dose reductions and dose delays.8 Failure to deliver planned chemotherapy can therefore be a major consequence of FN, that should be prevented as a clinical priority.9

Biosimilar medicines are playing an increasingly important role in the oncology treatment pathway within the UK health system. Pelmeg® offers a patient centric, effective alternative treatment option at a vital point in cancer care that can help address both the resource pressures on the health system, as well as patient needs.

Paul Clark, Director of Biosimilars at Napp Pharmaceuticals Ltd said “We are proud to be delivering treatments that address patient need in the oncology treatment pathway and that could potentially improve patient experience at such a critical time. We hope that Pelmeg® will not only help to alleviate some of the resource pressures on the NHS by providing a more affordable long-acting treatment option, but that it may also help improve patient access to these vital medicines.”

About Pelmeg®

Pelmeg® is a pegfilgrastim biosimilar.10 Pegfilgrastim is a pegylated version of granulocyte-colony stimulating factor (G-CSF) that works by stimulating the bone marrow to produce more neutrophils, thereby reducing the duration of neutropenia and the incidence of febrile neutropenia in adults treated with cytotoxic chemotherapy for malignancy (with the exception of chronic myeloid leukaemia and myelodysplastic syndromes).2  It is administered as a subcutaneous injection once per chemotherapy cycle, at least 24 hours after cytotoxic chemotherapy.2

The approval of Pelmeg® was based on a robust regulatory submission of rigorous analytical, biofunctional, preclinical and clinical studies to demonstrate biosimilarity in terms of its quality, safety and efficacy profile compared with the reference pegfilgrastim.10 As such, it is indicated in the exact same way as subcutaneous (pre-filled syringe) Neulasta®.11

About neutropenia and febrile neutropenia

People being treated with chemotherapy for cancer are at risk of dangerously low levels of a type of white blood cell called a neutrophil. Neutrophils play an important role in the immune system guarding against infection.12 FN is a low level of neutrophils in the blood accompanied by a fever.12 People with FN caused by chemotherapy treatment for cancer are at increased risk of severe infection and death.12
