Biosimilars of basiliximab

Basiliximab is a chimeric mouse-human monoclonal antibody to the α chain (CD25) of the IL-2 receptor of T cells. It is an immunosuppresant agent used to prevent immediate transplant rejection in people who are receiving kidney transplants, in combination with other agents.

Biosimilars of infliximab

Last update: 26 August 2016

Infliximab is a chimeric monoclonal antibody against tumour necrosis factor alpha (TNF-α). It is used to treat autoimmune diseases, such as ankylosing spondylitis, Crohn’s disease, psoriasis, psoriatic arthritis, rheumatoid arthritis, and ulcerative colitis.

Biosimilars of ranibizumab

Last update: 26 August 2016

Ranibizumab is a monoclonal antibody fragment created from the same parent mouse antibody as bevacizumab. Ranibizumab inhibits angiogenesis (the formation of new blood vessels) by inhibiting vascular endothelial growth factor A (VEGF-A), a mechanism similar to bevacizumab [1].

Biosimilars of omalizumab

Omalizumab is a recombinant DNA-derived humanized IgG1k monoclonal antibody that specifically binds to free human immunoglobulin E (IgE) in the blood and interstitial fluid and to membrane-bound form of IgE (mIgE) on the surface of mIgE-expressing B lymphocytes [1]. Unlike an ordinary anti-IgE antibody, it does not bind to IgE that is already bound by the high affinity IgE receptor (FcεRI) on the surface of mast cells, basophils, and antigen-presenting dendritic cells. The originator product Novartis’s Xolair (omalizumab) is indicated for the treatment of moderate to severe persistent asthma and chronic idiopathic urticaria despite antihistamine treatment.

Biosimilars approved in the US

Last update: 19 August 2016

In the US, a legal framework for approving biosimilars was established in 2009, via the Biologics Price Competition and Innovation Act of 2009 (BPCI Act).

‘Similar biologics’ approved and marketed in India

Last update: 19 August 2016

There have been established guidelines for approving generic versions of small molecule chemical drugs in India for some time already. However, no specific guidelines for ‘similar biologics’, as the Indian regulatory authorities call these products, have existed in India until recently. This has been the case despite the fact that the requirements for granting regulatory approval for such ‘similar biologics’ required more data than for a simple generic drug application [1].

Sandoz plans to launch five more biosimilars by 2020

Sandoz, the generics division of Novartis, has announced plans for five major global biosimilar launches by 2020.

Biosimilars of trastuzumab

Last update: 12 August 2016

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 over-expressed, and causes cancer cells to reproduce uncontrollably. Trastuzumab is therefore used to treat certain breast cancers.

Biosimilars of adalimumab

Last update: 12 August 2016

Adalimumab is a human monoclonal antibody that treats autoimmune diseases by inhibiting tumour necrosis factor (TNF); a soluble inflammatory cytokine. Adalimumab binds to TNF-alpha (TNFα), preventing it from activating TNF receptors, which cause the inflammatory reactions associated with autoimmune diseases. Adalimumab is indicated for the treatment of rheumatoid, juvenile idiopathic and psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, psoriasis and ulcerative colitis.

Biosimilars of etanercept

Last update: 5 August 2016

Etanercept is a biological drug that treats autoimmune diseases by inhibiting tumour necrosis factor (TNF); a soluble inflammatory cytokine. Etanercept is indicated for the treatment of rheumatoid, juvenile rheumatoid and psoriatic arthritis, plaque psoriasis and ankylosing spondylitis.
