Background: Infliximab seems to be the most efficacious of the three available anti-TNF agents for ulcerative colitis (UC) but little is known when it is used as the second anti-TNF., Objectives: To compare the clinical and treatment outcomes of a second subcutaneous or intravenous anti-TNF in UC patients., Design: Retrospective observational study., Methods: Patients from the ENEIDA registry treated consecutively with infliximab and a subcutaneous anti-TNF (or vice versa), naïve to other biological agents, were identified and grouped according to the administration route of the first anti-TNF into IVi (intravenous initially) or SCi (subcutaneous initially)., Results: Overall, 473 UC patients were included (330 IVi and 143 SCi). Clinical response at week 14 was 42.7% and 48.3% in the IVi and SCi groups (non-statistically significant), respectively. Clinical remission rates at week 52 were 32.8% and 31.4% in the IVi and SCi groups (nonsignificant differences), respectively. A propensity-matched score analysis showed a higher clinical response rate at week 14 in the SCi group and higher treatment persistence in the IVi group. Regarding long-term outcomes, dose escalation and discontinuation due to the primary failure of the first anti-TNF and more severe disease activity at the beginning of the second anti-TNF were inversely associated with clinical remission., Conclusion: The use of a second anti-TNF for UC seems to be reasonable in terms of efficacy, although it is particularly reduced in the case of the primary failure of the first anti-TNF. Whether the second anti-TNF is infliximab or subcutaneous does not seem to affect efficacy., Competing Interests: MC has served as a speaker for Takeda, Janssen, Faes Farma, and MSD; FC has served as a speaker or has received educational grants from Takeda, Janssen, MSD, and Ferring; MR has served as a speaker or has received research or educational funding or advisory fees from MSD, Abbvie, Pfizer, Takeda, and Janssen; MI has served as a speaker or has received research or educational funding or advisory fees from MSD, Janssen, Adacyte, and Takeda; LC has served as a speaker or has received research or educational funding or advisory fees from Abbvie, Dr. Falk Pharma, and Tillots Pharma; LB has served as a speaker or has received research or educational funding or advisory fees from Ikan Biotech; MBA has served as a speaker or has received research or educational funding or advisory fees from MSD, AbbVie, Janssen, Kern Pharma, Celltrion, Takeda, Gillead, Celgene, Pfizer, Sandoz, Biogen, Fresenius, Ferring, Faes Farma, Dr. Falk Pharma, Chiesi, Gebro Pharma, Adacyte, and Vifor Pharma; CG-M has received educational funding fees from AbbVie, Janssen, Pfizer, Ferring, Kern Pharma, Norgine, and Tillots Pharma; JMH has served as a speaker or has received research or educational funding or advisory fees from Merck Sharp & Dohme, Ferring, Abbvie, Janssen, Biogen, Sandoz, Kern Pharma, Faes Farma, Vifor Pharma, and Takeda; RL has served as a speaker or has received research or educational funding or advisory fees from MSD, Abbvie, Pfizer, Takeda, Janssen, and Dr. Falk; AM-C has received research or educational funding from Abbvie, Biogen, Ferring, Janssen, MSD, Takeda, Dr. Falk Pharma, and Tillotts; JPG has served as a speaker or has received research or educational funding or advisory fees from MSD, Abbvie, Pfizer, Kern Pharma, Biogen, Mylan, Takeda, Janssen, Roche, Sandoz, Celgene/Bristol Myers, Gilead/Galapagos, Lilly, Ferring, Faes Farma, Shire Pharmaceuticals, Dr. Falk Pharma, Tillotts Pharma, Chiesi, Casen Fleet, Gebro Pharma, Otsuka Pharmaceutical, Norgine, and Vifor Pharma; FG has served as a speaker or has received research or educational funding or advisory fees from Faes-Farma, Galápagos, Takeda, Pfizer, Janssen, and Abbvie; PA has served as a speaker or has received research or educational funding or advisory fees from MSD, Abbvie, Takeda, Janssen, Gebro Pharma, Tillotts Pharma, and Biogen; CT has served as a speaker or has received research or educational funding or advisory fees from MSD, AbbVie, Pfizer, Takeda, Janssen, Ferring, Faes Farma, Shire Pharmaceuticals, Dr. Falk Pharma, Galapagos, and Tillots; IR-L has served as a speaker or has received research or educational funding or advisory fees from MSD, Pfizer, Abbvie, Takeda, Janssen, Tillotts Pharma, Kern, Celltrion, Roche, Ferring, Dr. Falk Pharma, Galapagos, Otsuka Pharmaceutical, and Adacyte; MM has served as a speaker and has received research or educational funding from MSD, AbbVie, Takeda, Janssen, Ferring, and Pfizer; ED has served as a speaker or has received research or educational funding or advisory fees from AbbVie, Adacyte Therapeutics, Biogen, Celltrion, Galapagos, Gilead, Janssen, Kern Pharma, MSD, Pfizer, Roche, Samsung, Takeda, and Tillots; MJG has served as a speaker or has received research or educational funding or advisory fees from Janssen, Pfizer, Abbvie, Takeda, Kern Pharma, and Ferring; MA has served as a speaker or has received research or educational funding or advisory fees from Faes, Ferring, and Janssen, and received educational grants from Janssen; JRP has served as a speaker or has received research or educational funding or advisory fees from MSD, AbbVie, and Tillots Pharma; FB received educational funding fees from AbbVie, Janssen, Pfizer, Ferring, Kern Pharma, Norgine, and Tillots Pharma.
