CLINIGEN To Begin Supplying Erwinaze® in the UK

Clinigen Group plc (AIM: CLIN, ‘Clinigen’), the global pharmaceutical Products and Services company, today announces that it will be providing access to Erwinase® (L-asparaginase Erwinia chrysanthemi) in the UK from the 6 April 2021. This is part of the global exclusive licensing and distribution agreement with Porton Biopharma (‘PBL’), as previously announced on 16 April 2020.


Erwinase is approved in the UK as a component of a chemotherapeutic regimen for the treatment of patients with acute lymphoblastic leukaemia (ALL) who have developed hypersensitivity to E. coli-derived asparaginase. Erwinase is manufactured by PBL (PL 44403/0002) and Clinigen is responsible for marketing, packaging, labelling, storage and distribution.


With the onboarding of Erwinase coming earlier than originally anticipated this will bring forward an expected investment in working capital in-line with our previous guidance of £10m - £20m. Given the proximity to the year end and staggered roll out across each territory this is not expected to have a material impact on current year profit expectations.


Sam Herbert, Chief Operating Officer, Clinigen, said:


“Erwinase® is an important treatment option for healthcare professionals in the UK and this represents a major milestone since partnering with PBL. PBL has invested in enhancing its manufacturing to increase Erwinase® capacity and our ongoing focus is to ensure effective future supply in the UK and in other international markets where patients need access. At Clinigen our mission is to ensure the right medicines get to the right patients at the right time and we see Erwinase® as a key part of that mission.”

About Erwinase® / Erwinaze®


Erwinase is indicated as a component of a chemotherapeutic regimen for the treatment of patients with acute lymphoblastic leukaemia (ALL) who have developed hypersensitivity to E. coli-derived asparaginase. Erwinase is indicated in paediatric patients from the age of 4 months and in adults.


Asparagine is an amino acid that is essential for cell growth; it is produced by most but not all cells. Mutated cancer cells in ALL rely on asparagine circulating in the blood for growth. L-asparaginases are a group of enzymes that lower circulating asparagine levels in the blood, thereby depriving the mutated cells of asparagine and inhibiting their growth.


There are several different types of L-asparaginase available on the market, each derived from a different bacterium. Patients receiving treatment with L-asparaginase derived from Escherichia coli (E. coli), who develop hypersensitivity to that form of the enzyme, may be able to continue treatment with Erwinase as the enzymes are immunologically distinct. Antibodies targeting E. coli derived L-Asparaginase have been shown not to cross-react with Erwinase.


About Acute Lymphoblastic Leukaemia (ALL)


Acute lymphoblastic leukemia (ALL) is a heterogenous hematologic disease characterized by the proliferation of immature lymphoid cells in the bone marrow, peripheral blood and other organs. Both adults and children can get the illness, but it is most often diagnosed in younger people. The incidence in the EU is thought to be 1.28 per 1 000 000 individuals annually, with significant age-related variations. Estimated new ALL cases in the US was estimated to be 6150 in 2020 according to the SEER program.
