Celltrion
(KRX:068270) applied for the clinical trials for its adalimumab
biosimilar ‘CT-P17', as a rheumatoid arthritis therapeutic agent, to the
MHRA (Medicines and Healthcare Products Regulatory Agency) in the UK.

Celltrion is set to launch phase 1 clinical trials for the safety and
pharmacokinetic assessment of the adalimumab biosimilar in the UK. And
Celltrion also conducts global phase 3 clinical trials in about 75 sites
in eight nations in European region from August 2018. It aims to
complete phase 3 clinical trials by 2020.

The Abbvie's HUMIRA®, the original medicine of CT-P17, is a
therapeutic biopharmaceutical for the treatment of rheumatoid arthritis,
inflammatory bowel disease, psoriatic arthritis, ankylosing spondylitis,
etc., and it recorded sales of about USD 18.4 billion in 2017,1
making it the global largest-selling blockbuster medicine.

Celltrion has developed CT-P17 as a high-concentration formulation and
thus differentiated it from the competitive biosimilars which are
conducting clinical trials or have already been approved.

Meanwhile, after completing clinical trials for CT-P17, Celltrion is set
to maximize its market share in TNF-α inhibitor biosimilar markets under
the strategy of diversifying its TNF-α inhibitors along with Remsima®,
already sharing 52%2 of the Europe's original medicine
market, and CT-P13 SC which is undergoing clinical trials with the goal
of obtaining approvals in 2019.
