Assessment of efficacy and safety of biosimilars in rheumatology

Biosimilars/Research | Posted 16/08/2013

During the last decade, the availability of biological therapies has revolutionized the treatment of rheumatoid arthritis. Biologicals, unlike small-molecule chemical drugs, are extremely complex molecules, making producing biosimilars far from a simple process.

Cost savings from use of biosimilars in rheumatology

Biosimilars/Research | Posted 09/08/2013

The treatment of rheumatoid arthritis provides a clear argument in favour of developing biosimilars and the need to collect sufficient pharmacological data to validate their bioequivalence and interchangeability.

South Korean biotechnology company Celltrion presented results of its extended trials for its biosimilar infliximab candidate Remsima (CT-P13) at the European League Against Rheumatism (EULAR) 2013 Conference, which was held in Madrid, Spain on 12–15 June 2013.

Erythropoietin biosimilars in bone marrow transplantation and stem cell donation

Biosimilars/Research | Posted 28/06/2013

Combination therapy with granulocyte colony-stimulating factor (G-CSF) and erythropoietin (EPO) has been used with the aim of accelerating the recovery of red blood cells following autologous bone marrow transplantation [1]. Previous studies have shown, however, that this practice has no significant effect on erythroid recovery and transfusional requirements.

Use of G-CSF biosimilars for reduction of fever

Biosimilars/Research | Posted 14/06/2013

The American Society of Hematology, the British Society of Haematology, the European Society of Hematology and the European Group of Bone Marrow Transplantation all recommend the use of granulocyte colony-stimulating factor (G-CSF) after transplant in order to reduce the time to neutrophil recovery and the number of days with fever.

Positive post-marketing data for biosimilar epoetin

Biosimilars/Research | Posted 07/06/2013

Injectable generics specialist, Hospira, presented results from a post-marketing study of the company’s European biosimilar epoetin (Retacrit) on 3 June 2013 at the 48th Annual Meeting of the American Society of Clinical Oncology (ASCO) held in Chicago, USA.

Use of G-CSF biosimilars for stem cell mobilization in autologous transplantation

Biosimilars/Research | Posted 07/06/2013

The first biosimilar granulocyte colony-stimulating factor (G-CSF) was licensed by EMA in 2008, and there are currently six biosimilar G-CSF products licensed for use in the EU [1]. All of these biosimilars are also approved for haematopoietic stem cell transplantation.

Biopharmaceutical products in Iran

Iran will become a leader in biotechnology products (especially copied biopharmaceuticals [1]) in Asia over the next three years, according to a review by Mahboudi et al. [2].

Use of G-CSF biosimilars for stem cell mobilization in healthy donors

Biosimilars/Research | Posted 24/05/2013

Granulocyte colony-stimulating factor (G-CSF) can be used to mobilize peripheral blood stem cells (PBSCs) in healthy donors. Over the last 10 years, the procedure has become the preferred option for donors compared to the donation of bone marrow.

Saving money in the European healthcare system with biosimilars

Biosimilars/Research | Posted 16/11/2012

Biotechnology-derived medicines are increasingly popular for treating a range of conditions from cancer to autoimmunity, and yet they are among the most expensive healthcare products owing to their manufacture using live cell cultures. As healthcare providers become increasingly concerned about rising costs, interest is turning to the idea of substituting reference biological drugs with cheaper but similar biological products, or biosimilars, after patents expire on reference products. The use of biosimilars has the potential to reduce healthcare expenditure, particularly for long-term treatments, which incur high annual treatment costs.

Development of biosimilars for rheumatology

Biosimilars/Research | Posted 03/05/2013

In 2012, worldwide sales for the top three selling tumour necrosis factor (TNF) inhibitors reached US$20 billion. These biological treatments for arthritis are costing patients between US$10,000–US$30,000 per year making the need for lower cost biosimilars clear [1].

Research on clinical trial issues for biosimilars

Biosimilars/Research | Posted 19/04/2013

Period: September to December 2012

In order to demonstrate comparability between a biosimilar and its reference product, EMA recommends that the clinical trial should make it possible to detect a difference between the biosimilar and reference product. In most cases, this means that a two-arm clinical trial design (reference biological and biosimilar) in a small group of homogenous patients may be used. If the two arms of the trial produce similar results, then the biosimilar can be approved.

Quality, similarity and safety of biosimilars

Biosimilars/Research | Posted 12/04/2013

An abbreviated pathway for the approval of biosimilars was implemented in the EU in 2005. Despite biosimilars being available in Europe for more than seven years, physicians still have concerns about the use of biosimilars. Members and experts of the Working Party on Similar Biologic Medicinal Products of the European Medicines Agency (EMA) highlight what physicians need to know to make informed and appropriate treatment choices for their patients [1].

Phase I/IIb trial of CT-P6 shows comparability to trastuzumab

Biosimilars/Research | Posted 12/04/2013

Results of a phase I/IIb trial for South Korean biotechnology company Celltrion’s biosimilar candidate CT‑P6 were presented at the 13th St Gallen International Breast Cancer Conference held in St Gallen, Switzerland, on 13–16 March 2013. The results demonstrated the comparable pharmacokinetics and safety of CT-P6 to the reference drug.

Research on biosimilars in anaemia and diabetes

Biosimilars/Research | Posted 05/04/2013

Period: September to December 2012

The use of biological medicines has been life-changing for many patients suffering with anaemia and diabetes. With the expiration of patents on these biologicals the possibility of patients gaining access to lower cost biosimilar alternatives to these extremely effective, but costly, medicines becomes a real possibility.

Biosimilars in rheumatology

Biosimilars/Research | Posted 29/03/2013

Patents on key biological medicines used in rheumatology will expire soon. The European Medicines Agency’s (EMA’s) finalized guidelines on biosimilar monoclonal antibodies (mAbs) came into effect on 1 December 2012. Both of these facts mean that rheumatologists can expect to be exposed to biosimilars of the medicines they routinely use in the near future.

How are biosimilars special

Biosimilars/Research | Posted 22/03/2013

Despite biosimilars being around in the EU since 2006 physicians are still often reluctant to prescribe them. Members and experts of the Working Party on Similar Biologic Medicinal Products of the European Medicines Agency (EMA) highlight what physicians need to know to make informed and appropriate treatment choices for their patients [1].

Biosimilars/Research | Posted 20/05/2011

Last updated: 4 April 2013

Sandoz researchers found quality changes in commercially available rituximab (Rituxan/Mabthera) over a period of time. Since the drug remained on the market with an unchanged label, this would indicate that the changes were accepted by the health authorities.
