Brief Summary:

A placebo controlled study of two doses of HMPL-004 in patients with active mild to moderate ulcerative colitis (UC), with a modified Mayo Score 4-10 and an endoscopy subscore of 2-3, taking mesalamine (or equivalent) as a concomitant medication.

The objective is to evaluate the efficacy and safety of HMPL-004 with mesalamine (mesalamine treatment failures). Efficacy will be measured by a comparison of the proportion of patients in each treatment group attaining clinical remission at Week 8 as compared to placebo.


Condition or disease Intervention/treatment Phase
Ulcerative Colitis Drug: HMPL-004 1800 mg/day Drug: Placebo Drug: HMPL-004 2400 mg/day Phase 3

Detailed Description:

This Phase III study of HMPL-004 was to enroll approximately 420 subjects with active mild to moderate ulcerative colitis (UC; modified Mayo Score 4-10 and endoscopy score of 2-3). The trial included male and female subjects aged 18 or older. Subjects were currently receiving ≥2.4 g/day mesalamine or equivalent, provided they had taken 5-aminosalicylate (ASA; i.e., mesalamine) at a dose ≥2.4 g/day for at least 6 weeks prior to randomization and were on a stable dosage for at least 2 weeks prior to entering the screening phase of the study.

Qualifying subjects who entered into this study received 3 daily doses of oral HMPL 004 tablets or placebo for 56 days (8 weeks). There were 3 arms in this study consisting of placebo, HMPL-004 600 mg three times a day (TID) or 800 mg TID. Approximately 420 subjects were to be randomized 1:1:1 to one of these 3 arms, stratified by country/region in up to 150 clinical centers in North America, Europe, and Asia.

Primary Outcome Measures :
  1. Percentage of Subjects With a Clinical Remission at Week 8 [ Time Frame: 8 weeks ]
    Clinical remission was defined as a total Mayo Score of ≤2 points with no individual sub-score >1 point and rectal bleeding score = 0.


Secondary Outcome Measures :
  1. The Proportion of Subjects With Clinical Response at Week 8 [ Time Frame: 8 weeks ]
    Clinical response was defined as a decrease in a modified Mayo Score from baseline by ≥3 points and ≥30% decrease in the modified Mayo Score, along with either a decrease in the rectal bleeding score ≥1 or an absolute rectal bleeding score ≤1.

  2. The Proportion of Subjects With Mucosal Healing at Week 8 [ Time Frame: 8 weeks ]
    Mucosal healing was defined as having normal or inactive disease using a modified Mayo Score to determine if the decrease in the modified Mayo endoscopy sub-score from baseline was ≥1 in at least 1 segment and had an absolute score ≤1 in all segments.
