Colitis Ulcerative, Crohn's Disease
Conditions
Brief summary
LTS19689 is a multinational, multicenter extension study to evaluate the long-term safety, tolerability and efficacy of balinatunfib in participants with Crohn's disease (CD) or ulcerative colitis (UC) who completed the 52-week treatment period (on balinatunfib or placebo) in the parent studies, SPECIFI-CD (DRI18212) or SPECIFI-UC (DRI17822), respectively. * The primary objective of this study is to assess the long-term safety and tolerability of different doses of balinatunfib in participants with CD or UC, as measured by the number and percentage of participants with CD or UC with treatment emergent adverse events (TEAEs), serious adverse events (SAEs) and adverse events of special interest (AESIs) during the study period. * The study will consist of 2 independent cohorts through the study given the distinct nature of each disease: * CD Cohort: comprised of CD participants enrolled from SPECIFI-CD (DRI18212). * UC Cohort: comprised of UC participants enrolled from SPECIFI-UC (DRI17822). * The study will consist of the following study periods for each cohort: * A Double-Blind (DB) treatment period of up to 104 weeks for eligible participants from the DB maintenance phases of the respective parent studies. * An Open-Label (OL) treatment period of up to 104 weeks for: * Eligible participants from either the DB or OL periods of the parent studies, * Eligible participants who meet escape criteria at any time during the DB period of the LTS19689. * A 2-week follow-up period following the End of Treatment (EOT). The study duration will be up to 107 weeks, with the treatment duration up to 104 weeks.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Number of participants with Crohn's Disease with treatment emergent adverse events (TEAEs), serious adverse events (SAEs) and adverse events of special interest (AESIs) | Up to End of Study (approximately 106 weeks) |
| Number of participants with ulcerative colitis with treatment emergent adverse events (TEAEs), serious adverse events (SAEs) and adverse events of special interest (AESIs) | Up to End of Study (approximately 106 weeks) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of participants with Crohn's Disease in endoscopic remission based on simple endoscopic score for Crohn's disease (SES-CD) | Week 52 | Endoscopic remission is defined as SES-CD ≤4 points (SES CD ≤2 points for isolated ileal disease) and a SES-CD decrease ≥2 points with no SES-CD subscore \>1 point from baseline. The SES-CD evaluates 4 endoscopic items (ulcer size, ulcerated surface, affected surface, and narrowing, each on a scale from 0 (none) to 3 in 5 segments assessed during ileocolonoscopy (ileum, right colon, transverse colon, sigmoid and left colon, and rectum). The total score is the sum of the 4 endoscopic variable scores and ranges from 0 to 56, where higher scores indicate more severe disease. |
| Proportion of participants with Crohn's Disease in clinical remission based on Crohn's disease activity index (CDAI) | Week 52 | Clinical remission is defined as CDAI \<150. The CDAI score is composed of eight items: 3 of them (abdominal pain, stool frequency and general well-being) completed by the participant and the others (use of anti-diarrheal medications, extraintestinal complications, palpable abdominal mass, hematocrit levels, and body weight) assessed and reported by the clinician. The CDAI is derived from summing up the weighted individual scores of eight items. Scores on the CDAI scale range from 0 to 600, with higher scores indicating more severe disease. |
| Proportion of participants with ulcerative colitis in clinical remission based on modified Mayo Score (mMS) | Week 52 | Clinical remission by modified Mayo score (mMS) is defined as a mMS score of 0 to 2, including stool frequency (SF) of 0 or 1, rectal bleeding (RB) subscore of 0, and centrally read modified Mayo Endoscopic Subscore \[mMES\] of 0 or 1 (score of 1 modified to exclude friability).Each component of the mMS (SF, RB, and mMES) is scored from 0 to 3. The total mMS ranges from 0 to 9 with higher scores indicating greater disease severity |
