Ulcerative Colitis Clinical Trials in San Marcos, TX

The purpose of this protocol is to evaluate the efficacy and safety of tulisokibart in participants with moderately to severely active ulcerative colitis. Study 1's primary hypotheses are that at least 1 tulisokibart dose level is superior to Placebo in the proportion of participants achieving clinical remission per Modified Mayo Score at Week 12, and that at least 1 tulisokibart dose level is superior to Placebo in the proportion of participants achieving clinical remission per Modified Mayo Score at week 52. Study 2's primary hypothesis is that at least 1 tulisokibart dose level is superior to Placebo in the proportion of participants achieving clinical remission per Modified Mayo Score at Week 12.

This is a multicenter, randomized, placebo controlled study to evaluate the efficacy and safety of ABX464 given at 25 or 50 mg QD in inducing clinical remission in subjects with moderately to severely active ulcerative colitis who have inadequate response, no response, a loss of response, or an intolerance to either conventional therapies [corticosteroids, immunosuppressant (i.e. azathioprine, 6-mercaptopurine, methotrexate)] and/or advanced therapies [biologics (TNF inhibitors, anti-integrins, anti-IL-23), and/or S1P receptor modulators, and/or JAK inhibitors].

The purpose of this open-label extension (OLE) study is to evaluate the safety and efficacy of etrasimod in participants with moderately to severely active ulcerative colitis (UC) who previously received double-blind treatment (either etrasimod 2 mg per day or placebo) during participation in one of the qualified Phase 3 or Phase 2 double-blind, placebo-controlled parent studies including but not limited to: (APD334-301 [NCT03945188] or APD334-302 [NCT03996369] or APD334-210 [NCT04607837]).

This is a multicenter, randomized study to evaluate the long-term efficacy and safety of ABX464 50mg and 25mg administered once daily (QD) as maintenance therapy in subjects with moderately to severely active ulcerative colitis who have inadequate response, no response, a loss of response, or an intolerance to either conventional therapies [corticosteroids, immunosuppressant (i.e. azathioprine, 6-mercaptopurine, methotrexate)] and/or advanced therapies [biologics (TNF inhibitors, anti-integrins, anti-IL-23), and/or S1P receptor modulators, and/or JAK inhibitors]. This study is the maintenance phase of both previous induction studies ABX464-105 and ABX464-106. All eligible subjects who have completed either one of the induction studies above mentioned, will be given the opportunity to take part in the present ABX464-107 maintenance study and will be randomized to either a double blind, placebo-controlled part (Part #1) or allocated to ABX464 50mg or 25mg open label treatment arms (Part #2) depending on their clinical response at the end of induction. This study consists of a 44-week treatment phase and a 28-days follow-up period consisting in the End of Study (EOS) visit. Read Less
