US supreme court ruling means biosimilars pathway safe
On 28 June 2012 the US Supreme Court ruled in favour of the bulk of the Affordable Care Act, meaning that the biosimilars pathway, which is part of the act, is now also safe.
Biosimilar infliximab equivalence proven in phase III trial
Results from a phase III trial of biosimilar infliximab have proven the equivalence of South Korean biotechnology company Celltrion’s biosimilar (CT-P13) and the reference product – Johnson & Johnson’s rheumatoid arthritis blockbuster Remicade (infliximab) in terms of safety and efficacy in patients with active rheumatoid arthritis [1].
Copaxone sees off generics challenge

Phase I trial of biosimilar infliximab proves biosimilarity
Results from a phase I trial of biosimilar infliximab have proven the equivalence of South Korean biotechnology company Celltrion’s biosimilar (CT-P13) and the reference product – Johnson & Johnson’s rheumatoid arthritis blockbuster Remicade (infliximab) in terms of pharmacokinetic parameters, as well as in safety and efficacy in patients with active ankylosing spondylitis [1].
Small molecule versus biological drugs
Biological drugs are large and complex, often consisting of heterogeneous mixtures. They are generally made in genetically engineered cells that impose their own variabilities–in post-translation modifications such as glycosylation–on the processes used to make such drugs.
