About this study

Official title: A Phase III, Multicenter, Double-Blind, Placebo-Controlled, Re-randomized Study To Assess the Efficacy and Safety With Hemay005 Tablets in Chinese Patients With Moderately to Severely Active Ulcerative Colitis

The purpose of this phase III, multicenter, double-blind, placebo-controlled study is to evaluate the efficacy and safety of Hemay005 compared to placebo as induction and maintenance therapy in Chinese participants with moderately to severely active ulcerative colitis.

Read the detailed description

This study is a phase 3, multicenter, randomized, double-blinded, placebo-controlled, parallel-group study to examine the efficacy, safety of Hemay005 in induction and maintenance therapy in Chinese patients with moderately or severely active ulcerative colitis. The study consists of two independent phases: an 12-week Induction Phase (might including an 12-week Extended Induction phase, depending on the participant status by the end of the induction treatment) and a 40-week Maintenance Phase. Screening period will be up to 5 Weeks.

In the Induction Phase, participants will be randomized 2:1 to receive either Hemay005 (twice daily) or placebo for 12 weeks. The randomization will be stratified by: exposed to advanced therapy (yes/no); disease severity (modified Mayo score of 5-6 or 7-9) and baseline corticosteroid use (yes/no). Participants who have not show clinical response (either receive Hemay005 or placebo) by week 12 will undergo an extended 12-week induction treatment with Hemay005.

After completing the Induction Phase (or the Extended Induction Phase), participants with response are eligible to go to the Maintenance Phase. Participants with a response to Hemay005 by week 12 of the Induction Phase and those with a response by the end of the Extended Induction Phase) will be randomized 1:1 to receive either Hemay005 (twice daily) or placebo for 40 weeks. Randomization will be stratified by corticosteroid use at the start date of Maintenance Phase (yes/no) and clinical remission status by the end of Induction Phase (yes/no). Participants who are assigned to placebo during the Induction Phase and have demonstrated a clinical response will continue to receive blinded placebo during the Maintenance Phase. Participants who have not showed a clinical response by week 12 of the Induction Phase but have a response to Hemay005 by the end of the Extended Induction Phase will continue to receive blinded Hemay005 during the Maintenance Phase.

During the Maintenance Phase, participants who are demonstrated loss of response will be eligible to go to the open-label treatment phase and treated with Hemay005. The total duration of open-label treatment phase will not exceed 40 weeks since the participant enrolled into the Maintenance Phase.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Induction Phase: Percentage of Participants With Clinical Remission at Week 12.

    Clinical remission is based on the Modified Mayo Score (mMS). The Modified Mayo Score (mMS) consists of Rectal Bleeding Subscore (RBS), Stool Frequency Subscore (SFS) and Mayo Endoscopic Subscore (MES). Each subscore ranges from 0 to 3 and a total mMS ranging from 0 to 9, with higher scores indicating more severe disease. Clinical remission is defined as a SFS of 0 or 1 with a decrease of at least 1 from baseline , and a RBS of 0, and a MES of 0 or 1 without friability.

    Measured: Induction Phase Week 12

  2. Maintenance Phase: Percentage of Participants With Clinical Remission at Week 40.

    Clinical remission is defined as a SFS of 0 or 1 with a decrease of at least 1 from baseline , and a RBS of 0, and a MES of 0 or 1 without friability.

    Measured: Maintenance Phase: Week 40

Secondary outcomes (14)
  1. Induction Phase: Percentage of Participants With Endoscopic Improvement at Week 12.

Each subscore ranges from 0 to 3 and a total mMS ranging from 0 to 9, with higher scores indicating more severe disease. Clinical Response is defined as a decrease in mMS of at least 2 points and 30% from baseline and either a decrease of at least 1 in RBS or a RBS of 0 or 1.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 16 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Han Hai (86-22-24929530, haihan@hemay.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Induction Phase: Percentage of Participants With Clinical Remission at Week 12. (time frame: Induction Phase Week 12). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jun 2026.
