Un estudio para investigar la seguridad, tolerabilidad y eficacia a largo plazo de Balinatunfib en participantes con enfermedad de Crohn o colitis ulcerosa (SPECIFI-IBD-LTS)

19 de octubre de 2026 actualizado por: Sanofi

Estudio de extensión multinacional y multicéntrico para investigar la seguridad, tolerabilidad y eficacia a largo plazo de Balinatunfib en adultos con enfermedad de Crohn o colitis ulcerosa

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.

Descripción

Inclusion Criteria:

Participants are eligible to be included in the study only if all of the following criteria apply:

  • Participants with Crohn's Disease (CD) or ulcerative colitis (UC) who completed treatment at Week 52 of the SPECIFI-CD (DRI18212) or SPECIFI-UC (DRI17822) studies, respectively:

    • Participants with CD

      1. who complete double-blinded treatment at Week 52 of SPECIFI-CD (DRI18212) study;

      2. who complete open label treatment and achieve the appropriate outcomes at Week 52 of SPECIFI-CD (DRI18212) study.

        OR

    • Participants with UC

      1. who complete double-blinded treatment at Week 52 of SPECIFI-UC (DRI17822) study;
      2. who complete open label treatment and achieve the appropriate outcomes at Week 52 of the SPECIFI-UC (DRI17822) study.
  • Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. Women participants should not be pregnant or breastfeeding

Exclusion Criteria:

  • Participants with CD who develop a new medical condition precluding participation as described in Exclusion criteria of SPECIFI-CD (DRI18212) clinical trial protocol.
  • Participants with UC who develop a new medical condition precluding participation as described in Exclusion criteria of SPECIFI-UC (DRI17822) clinical trial protocol.
  • Participants who developed a new medical condition or a change in status of an established medical condition which (per Investigator's medical judgment) would adversely affect the participation in this study or would require permanent IMP discontinuation.
  • Participants who permanently discontinued IMP during the parent study or temporarily discontinued IMP for more than 14 consecutive calendar days by the time of Day 1 of LTS19689.
  • Participants who, during their participation in the parent study, developed an adverse event (AE) or a serious adverse event (SAE) deemed related to balinatunfib, which in the opinion of the Investigator could indicate that continued treatment with balinatunfib may present an unreasonable risk for the participant.
  • Participants who in the parent study had documented nonadherence to IMP or to standard therapies for CD or UC, or who used a prohibited medication concomitant with IMP or during a temporary IMP discontinuation period.

The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.

Medida Descripción
Periodo de tiempo
Proportion of participants with Crohn's Disease in endoscopic remission based on simple endoscopic score for Crohn's disease (SES-CD)
Periodo de tiempo: 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.

Week 52
Proportion of participants with Crohn's Disease in endoscopic remission based on simple endoscopic score for Crohn's disease (SES-CD)
Periodo de tiempo: Week 104

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.

Week 104
Proportion of participants with Crohn's Disease in clinical remission based on Crohn's disease activity index (CDAI)
Periodo de tiempo: 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.

Week 104
Proportion of participants with ulcerative colitis in clinical remission based on modified Mayo Score (mMS)
Periodo de tiempo: 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
