Celltrion’s biosimilar infliximab has positive results from pivotal study in Crohn’s Disease

Last week at the 12th Congress of the European Crohn’s and Colitis Organisation (ECCO), Celltrion Healthcare presented the primary outcome from its pivotal randomised controlled trial (RCT) of CT-P13 (biosimilar infliximab) in Crohn’s disease.

The data indicate that the safety and efficacy of CT-P13 in patients with moderate-to-severe Crohn’s disease (CD) is comparable to those treated with reference infliximab.

The Phase III RCT in 220 patients with CD examined whether CT-P13 is comparable to reference infliximab as determined by the Crohn’s Disease Activity Index (CDAI), a measurement used to quantify the symptoms of CD patients. According to the 6 week and 30 week data, similar clinical remission, CDAI-70 and CDAI-100 response rates were observed in both CT-P13 and reference infliximab treatment groups.

Leading expert Jørgen Jahnsen, Professor of Gastroenterology at the University of Oslo, Norway commented on the study, “This is the first RCT to examine the use of a biosimilar in inflammatory bowel disease. While we already have a wealth of extrapolated and real-world data for CT-P13, gastroenterologists have for some time wanted the reassurance of an RCT and it’s encouraging to see such positive data from Celltrion’s RCT trial.”

Celltrion Healthcare also presented data from two observational studies. The first study evaluated the efficacy and safety of CT-P13 in 74 paediatric patients with CD (naïve patients: 26, switch patients: 25) or ulcerative colitis (UC) (naïve patients: 16, switch patients: 7). The data show that CT-P13 is effective in both treatment-naïve and switch paediatric patients over 30 weeks and is well-tolerated.

The second study examined 204 CD patients (fistulising CD: 24, CD patients: 180) in South Korea from July 2012-2016. CT-P13 was found to be clinically consistent to reference infliximab and well tolerated up to six months in patients with moderate-to-severe CD and those with fistulising CD.
