EC approval for adalimumab biosimilar Imraldi

Barriers to the market access of biosimilar monoclonal antibodies

In September 2013, the first biosimilar monoclonal antibody (mAb) was approved by the European Medicines Agency (EMA), i.e. biosimilar infliximab (Inflectra/Remsima). These products entered the European market in 2015, after expiry of patent and other exclusivity rights of the innovator medicine Remicade. With the ever-increasing cost of health care and the economic pressure to reduce or sustain healthcare expenses, biosimilars could be instrumental in reducing cost for medication and increasing patient access to treatment. Although exclusivity rights of multiple mAbs are expired (rituximab in 2013, trastuzumab in 2014), only recently biosimilar mAbs other than infliximab are receiving marketing authorization (rituximab, adalimumab). Furthermore, earlier biosimilars have seen slow uptake in European markets. This may imply that several barriers hinder market access of biosimilar mAbs.

Biosimilars of insulin lispro

Last update: 26 January 2018

Insulin lispro is a fast acting insulin analogue used to treat people living with Type 1 or Type 2 diabetes. Insulin lispro has one primary advantage over regular insulin for postprandial glucose control. It has a shortened delay of onset, allowing slightly more flexibility than regular insulin, which requires a longer waiting period before starting a meal after injection. Both types should be used in combination with a longer acting insulin for good glycaemic control.

Real-life data supports efficacy and safety of biosimilar filgrastim

Biosimilars of filgrastim are widely used in the prophylaxis of chemotherapy‐induced (CIN) and febrile neutropenia (FN). However, there are limited observational data on the use of granulocyte colony-stimulating factor (G‐CSF) in non‐Hodgkin’s lymphoma (NHL) and its aggressive subtypes including diffuse large B‐cell lymphoma (DLBCL).

Scientific rationale for extrapolation of cancer indications

Extrapolation involves extending and applying the data from clinical studies regarding one medical condition to another medical condition. Once biosimilarity has been proven, biosimilars can also be approved for one or more additional indications held by the reference product, without the need for clinical data in those indications. Author Michinori Ogura from the Tokai Central Hospital, Gifu, Japan and colleagues from France and South Korea investigated the scientific rationale for extrapolation using the rituximab biosimilar CT-P10 as an example [1].

Trastuzumab biosimilar could reduce breast cancer treatment costs

Trastuzumab is a monoclonal antibody that interferes with the human epidermal growth factor receptor 2 (HER2)/neu receptor. In some cancers, notably certain types of breast cancer, HER2 is overexpressed, and causes cancer cells to reproduce uncontrollably. Trastuzumab is therefore used to treat certain breast cancers.

Japan-based biosimilars developer Fujifilm Kyowa Kirin Biologics announced on 22 May 2017 that its application for approval for its proposed adalimumab biosimilar (FKB327) had been accepted by the European Medicines Agency (EMA).

How the FDA regulates biosimilars

The advent of recombinant DNA-technology ushered in the development of novel therapeutic protein products that have become mainstays of treatment regimens against cancer, inflammatory disorders and other serious diseases and conditions. Recombinant therapeutic proteins are typically large, complex molecules that are produced in cultured cells and manufactured using complex, multistep purification processes. Despite some of these products being ‘off-patent’ for years, they remain among the most expensive pharmaceuticals in the US and the world. One approach that governments across the globe have taken to reduce healthcare costs is to give regulatory authorities the ability to approve biologicals using an abbreviated licensing pathway that includes achieving the rigorous standard of demonstrating ‘biosimilarity’ with an already approved biological product.

Biosimilars in the treatment of inflammatory bowel disease

Inflammatory bowel disease (IBD) is mainly characterized by two chronic, relapsing, immune-mediated inflammatory diseases of the gastrointestinal tract: Crohn’s disease and ulcerative colitis. Approximately 1.4 million Americans are affected by IBD and afflicted with recurrent symptoms of bloody diarrhoea, abdominal pain, bowel obstruction, and other co-morbid conditions. The introduction of biologicals, highly complex molecules manufactured from living organisms, was a revolutionary advance in treating threatening and life-debilitating inflammatory diseases. Biologicals, particularly those that target tumour necrosis factor (TNF) signalling, have provided IBD patients with an efficacious method of treatment with regards to symptom management and mucosal healing. Nevertheless, the rising prevalence of IBD worldwide and the ever-increasing cost burden of biologicals in the healthcare industry is alarming for insurance companies, clinicians and patients.

EMA guidance for NBCDs and products approved

The European Medicines Agency (EMA) has published reflection papers on nanomedicines and their follow-on versions [1]. It has also published a wide range of other guidance, which outlines the technical requirements to demonstrate the quality, safety and efficacy of medicines that may also be applicable to non-biological complex drugs (NBCDs), according to authors Ehmann and Pita [2].
