About this study

Official title: A Randomised, Controlled, Double-blind Exploratory Study of ND-12 Combined With H-6 in the Treatment of Adult Chronic Inflammatory Diarrhea

This is a randomized controlled trial to explore the efficacy and safety of ND-12 combined with H-6 for patients with chronic inflammatory diarrhea

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing mesalazine, ND-12 and ND-12/H-6 in people with Diarrhea Chronic and UC - Ulcerative Colitis, run by The Second Hospital of Nanjing Medical University at 1 site in China.

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 4 inclusion and 21 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: looking for participants now, as of the sponsor's last update on 17 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 Faming Zhang, PhD (086-025-58509883, fzhang@njmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fecal calprotectin of patients 14 days after treatment compared to the baseline level (time frame: baseline, 14 days post-drug administration). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07767370, which also lists 9 linked publications.

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 17 Aug 2026.
