Hospira launches first biosimilar monoclonal antibody (mAb) Inflectra (infliximab) in the UK

Hospira, Inc., a world leader in the development of biosimilar therapies, recently announced the UK launch of the first biosimilar monoclonal antibody (mAb), Inflectra (infliximab). Inflectra is licensed for the treatment of inflammatory conditions including rheumatoid arthritis (RA), psoriatic arthritis, ankylosing spondylitis, adult and paediatric Crohn’s disease, adult and paediatric ulcerative colitis and plaque psoriasis.

Biologic medicines have transformed the lives of people living with chronic inflammatory conditions, such as RA and inflammatory bowel disease (IBD). However biologics have been expensive treatments, imposing a considerable economic burden on the UK National Health Service (NHS).i Indeed biologics are responsible for some of the biggest medicinal costs across Europeii and these high costs can restrict access to treatment. For example, it has been estimated that 40% of RA patients in Europe have severely restricted access to biologic treatment.iii Inflectra can offer a cost-effective alternative while maintaining the same quality, safety and efficacy as the reference product.iv, v

Professional bodies and experts in the UK welcome the advent of biosimilars. The British Society of Gastroenterology (BSG) has welcomed the introduction of biosimilar medicines that will increase treatment options, generate price competition and ultimately benefit patients, as both necessary and desirable.vi

Professor Chris Probert, Honorary Consultant Gastroenterologist at the Institute of Translational Medicine, University of Liverpool and Chair of the IBD Section Committee for BSG said; “We are heading for exciting times in IBD as the forthcoming NICE guidance will recommend the use of biologics for UC patients who have failed conventional treatment. This move, together with the introduction of biosimilars such as Inflectra, means we can look forward to offering more of our patients the new standard of care. Biosimilars will help optimise NHS expenditure on biologics.”

Professor Ernest Choy, Head of Rheumatology and Translational Research at Cardiff University School of Medicine and Director of the Arthritis Research UK CREATE Centre and Welsh Arthritis Research Network said; “I am delighted that we now have access to Inflectra, the first biosimilar monoclonal antibody, as it could help to make biologic treatment more cost effective for the NHS and provide further opportunities to help patients get their disease under control.”

Infliximab is a cornerstone treatment for many inflammatory diseases, with over 15 years’ worth of clinical data and experience.vii Inflectra is a biosimilar medicine to the reference product, Remicade (infliximab), and is the first biosimilar mAb to be approved by the European Commission (EC). A biosimilar developed in-line with EU requirements can be considered a therapeutic alternative to an existing biologic.iii

Remicade (infliximab) has been authorised in the EU since 1999 and recorded European sales of almost €2 billion in 2013.viii The savings generated by introducing competition in the marketplace could save the European healthcare system millions of Euros, with biosimilar mAbs expected to produce savings of over €20 billion by 2020.ix

“Inflectra has already been launched in Central and Eastern Europe, and some smaller Western European markets due to earlier patent expiry, and has already been prescribed to treat patients in all its licensed indications. We are delighted that patients in the UK will now benefit from the availability of Inflectra. This supports Hospira’s commitment to provide patients with better access to high-quality, more affordable care,” said Paul Greenland, Vice President Biologics, Hospira.

Inflectra received its licence from the EC in September 2013, following adoption of the EMA Committee for Medicinal Products for Human Use (CHMP) positive recommendation for granting marketing authorisation. Review by the EMA included detailed analysis of biophysical properties and safety, efficacy and tolerability data from an extensive preclinical and clinical trial program.

In a phase III randomised, double-blind study involving 606 patients, Inflectra met its primary endpoint of therapeutic equivalence to Remicade. In this study, using the ACR20 scoring system, 73.4% of patients receiving Inflectra achieved a greater than or equal to 20% improvement in RA symptoms after 30 weeks of treatment, compared with 69.7% treated with Remicade.x In the same study, 42.3% of patients receiving Inflectra achieved a greater than or equal to 50% improvement in RA symptoms after 30 weeks of treatment (measured using the ACR50 scoring system), compared with 40.6% treated with Remicade.x Comparable safety and tolerability data also demonstrated Inflectra’s equivalence to Remicade. There were no marked differences in the immunogenicity profile of the two products up to 54 weeks, and the impact of anti-drug antibodies on efficacy and safety was comparable.x

Inflectra is now available in 26 European countries, with the UK among the most recent countries to approve this biosimilar. Hospira’s partner, Celltrion, has also submitted an application to the U.S. Food and Drug Administration for biosimilar infliximab.

With one of the largest biosimilar pipelines in the industry, Hospira has more than seven years’ of market experience in biosimilars. The company has several biosimilars on the European market, including Inflectra (infliximab), Retacrit (epoetin zeta) and Nivestim (filgrastim). Hospira has delivered more than 10 million doses of biosimilar medicines to patients worldwide.xi
