A Trial to Investigate PALI-2108 Versus Placebo in Participants With Moderately to Severely Active Ulcerative Colitis (ASCENTRA-UC)

2026年10月20日 更新者:Palisade Bio

A Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Dose Ranging Study to Evaluate the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of Induction and Maintenance Therapy With PALI-2108 in Participants With Moderately to Severely Active Ulcerative Colitis

The ASCENTRA-UC study is a phase 2 study testing PALI-2108 in patients with moderate to severe ulcerative colitis. Doses of drug will be compared against a placebo to see how well it works, how safe it is, and how the body responds to it.

Key Inclusion Criteria:

  • Documented clinical diagnosis of UC for ≥ 3 months prior to Screening. The diagnosis of UC must be confirmed by endoscopic and histologic evidence.

    • mMS of 5 to 9 (inclusive), AND
    • ES ≥ 2, AND
    • RB ≥ 1.

iii. Immunosuppressants: azathioprine ≥ 2 mg/kg/day, 6-mercaptopurine (6-MP) ≥ 1.0 mg/kg/day (or therapeutic 6-thioguanine nucleotide [6-TGN] level) for ≥ 12 weeks, or methotrexate ≥ 15 mg/week subcutaneous or intramuscular.

iv. Approved advanced therapies at the approved labelled dose:

  1. Anti-tumor necrosis factor (TNF), anti-integrin (vedolizumab), or anti-IL-12/23 for at least 8 weeks; anti-IL 23 for at least 12 weeks.
  2. Janus kinase (JAK) inhibitor for at least 8 weeks; sphingosine-1-phosphate receptor (S1PR) modulator for at least 12 weeks.

Note: Demonstration of intolerance requires no minimum dose nor duration of use.

b. Currently receiving one or more of the following treatments: i. Stable oral prednisone at ≤ 20 mg/day (or equivalent) or budesonide ≤ 9 mg for ≥ 2 weeks prior to randomization.

ii. Stable dose of thiopurine (azathioprine or 6-MP) for ≥ 4 weeks prior to randomization, and have started the treatment ≥ 12 weeks prior to randomization.

iii. Stable dose of oral aminosalicylates for ≥ 2 weeks prior to randomization.

Key Exclusion Criteria:• Diagnosis of Crohn's disease or IBD-Unclassified (IBD-U; indeterminate colitis) or a history of ischemic colitis or radiation colitis.

  • UC limited to rectum (< 15 cm from anal verge).
  • Any prior history of suicidal behavior (actual, interrupted, aborted attempt, or preparatory acts).
  • Columbia-Suicide Severity Rating Scale (C-SSRS) suicidal ideation type 4 or 5, or any active suicidal ideation with some intent to act.
  • Severe depression at Screening based on a validated scale threshold (e.g., Patient Health Questionnaire-9 [PHQ-9] ≥ 20, or PHQ-9 item 9 > 0) at Screening.
  • Failure or intolerance of > 3 classes of approved advanced therapies or > 4 approved individual advanced therapies.

主要结果指标

结果测量
措施说明
大体时间
Proportion of participants with clinical remission using the 3-component modified Mayo Score (mMS) at Week 12.
大体时间:Week 12

The Modified Mayo Score (MMS) is a composite score of ulcerative colitis (UC) disease activity on a scale of increasing severity from 0-9, calculated by summing three subscores: Endoscopic subscore (ES), scored on a scale of increasing severity from 0 (normal or inactive disease) to 3 (severe disease, such as spontaneous bleeding or ulceration); Stool frequency subscore (SFS), scored on a scale of increasing frequency from 0 (normal number of stools) to 3 (≥5 stools more than normal per day for the participant); and rectal bleeding subscore (RBS), scored on a scale of increasing severity from 0 (no blood seen) to 3 (blood alone passed). Clinical Remission is defined as an ES of 0 or 1, RBS of 0, and SFS of 0 or 1 and not greater than the baseline SFS.

大体时间
Proportion of participants with clinical response using 3-component mMS at Week 12.
大体时间:At 12 weeks

The Modified Mayo Score (MMS) is a composite score of ulcerative colitis (UC) disease activity on a scale of increasing severity from 0-9, calculated by summing three subscores: Endoscopic subscore (ES), scored on a scale of increasing severity from 0 (normal or inactive disease) to 3 (severe disease, such as spontaneous bleeding or ulceration); Stool frequency subscore (SFS), scored on a scale of increasing frequency from 0 (normal number of stools) to 3 (≥5 stools more than normal per day for the participant); and rectal bleeding subscore (RBS), scored on a scale of increasing severity from 0 (no blood seen) to 3 (blood alone passed). Clinical Remission is defined as an ES of 0 or 1, RBS of 0, and SFS of 0 or 1 and not greater than the baseline SFS.

At 12 weeks
Proportion of participants with endoscopic improvement at Week 12.
大体时间:Week 12

Endoscopic improvement is defined as Mayo endoscopic subscore (ES) of 0 or 1. The ES measures UC severity based on endoscopy on a 0-3 scale of increasing severity.

Week 12
Proportion of participants with HEMI at Week 12.
大体时间:Week 12

HEMI is defined as a Geboes score of 3.1 or less and ES of 0 or 1. The Geboes score is a histologic grading system for inflammation in UC with scores ranging from 0 to 5.4, with higher scores indicating more severe inflammation. ES measures UC severity based on endoscopy, scored from 0 (normal or inactive disease) to 3 (severe disease, such as spontaneous bleeding or ulceration).

Week 12
Proportion of participants with clinical remission using the 3-component mMS at Week 48.
大体时间:Week 48

The Modified Mayo Score (MMS) is a composite score of ulcerative colitis (UC) disease activity on a scale of increasing severity from 0-9, calculated by summing three subscores: Endoscopic subscore (ES), scored on a scale of increasing severity from 0 (normal or inactive disease) to 3 (severe disease, such as spontaneous bleeding or ulceration); Stool frequency subscore (SFS), scored on a scale of increasing frequency from 0 (normal number of stools) to 3 (≥5 stools more than normal per day for the participant); and rectal bleeding subscore (RBS), scored on a scale of increasing severity from 0 (no blood seen) to 3 (blood alone passed). Clinical Remission is defined as an ES of 0 or 1, RBS of 0, and SFS of 0 or 1 and not greater than the baseline SFS.

Week 48
Proportion of participants with endoscopic improvement at Week 48.
大体时间:Week 48

Endoscopic improvement is defined as Mayo endoscopic subscore (ES) of 0 or 1. The ES measures UC severity based on endoscopy on a 0-3 scale of increasing severity.

Week 48
