Phase III trial for subcutaneous Remsima completed Posted 19/10/2018

Celltrion Healthcare (Celltrion) announced on 29 August 2018 that it had completed a phase III study with the subcutaneous (SC) version of its infliximab biosimilar Remsima (CT‑P13).

The South Korean biotechnology company says that it is developing Remsima SC in a bid to increase its competitiveness in the TNF‑α inhibitor (autoimmune disease therapeutic agent) market through a ‘twin-track’ strategy together with the existing intravenous (IV) formulation of Remsima.

Since May 2016, Celltrion has conducted phase I and III clinical trials on the safety, pharmacokinetic and efficacy assessment of Remsima SC. The company announced in June 2018 that data had shown that the subcutaneous administration of its infliximab biosimilar (CT‑P13) was comparable in terms of efficacy and safety with IV administration of CT‑P13 (Remsima/Inflectra) up to Week 30 in patients with active Crohn’s disease (CD) [1].

As part of its ‘strategy to boost its TNF-α inhibitor market competitiveness’ the company says it is also developing its adalimumab biosimilar CT‑P17 as a ‘high-concentration formulation’.

Celltrion says that it is set to complete the clinical analysis for the subcutaneous administration of its infliximab biosimilar (CT‑P13) soon and expects to submit its application for Remsima SC to the European Medicines Agency (EMA) in the second half of 2018.

Celltrion received approval for the IV formulation of CT‑P13 as Remsima/Inflectra in Europe in September 2013 [2] and its partner Pfizer received approval for Ixifi (infliximab-qbtx) in the US in December 2017 [3]. Pfizer holds exclusive commercialisation rights of Celltrion’s Inflectra in the US.

Ixifi is not Celltrion's biosimilar. It's Pfizer's biosimilar. posted 22/10/2018 - by Tracker

End of this article, Ixifi is introduced as Celltrion's biosimilar. However, Ixifi is not the Celltrion's biosimilar but the Pfizer's bioismilar. Pfizer contract with Celltrion to sell Inflectra which is the infliximab biosimilar of Celltrion.
