What is being measured

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

  1. Postprandial distress syndrome response rate

    Postprandial Distress Syndrome Response, the number of weeks in which the subject responded to the postprandial distress syndrome was greater than 50% of the weeks throughout the treatment period.

    Response week, if the two symptoms of postprandial fullness and discomfort and early satiety decreased by ≥50% compared with the baseline per week, the response week was calculated by the diary card score.

    Measured: The end of Week 8

Secondary outcomes (10)
  1. postprandial distress syndrome score change from baseline

    "The dyspepsia symptom scoring criteria" consists of 5 items, with a minimum score of 0 and a maximum of 10 points for each item.

    0 points: asymptomatic; 1-3 points: mild disturbance, mild symptoms, almost no impact on daily life and work; 4-6 points: moderate disturbance, still tolerable, partially affecting daily life and work; 7-10 points: Severe disturbance, unbearable, unable to carry out daily life and work.

    The minimum score of the scale is 0 points, the maximum is 50 points, and the higher the score, the more serious the disease.

    Measured: The end of Week 8

  2. single symptom response rate

    Measured: The end of Week 8

  3. the change value of single symptom score from baseline

    "The dyspepsia symptom scoring criteria" consists of 5 items, with a minimum score of 0 and a maximum of 10 points for each item.

    0 points: asymptomatic; 1-3 points: mild disturbance, mild symptoms, almost no impact on daily life and work; 4-6 points: moderate disturbance, still tolerable, partially affecting daily life and work; 7-10 points: Severe disturbance, unbearable, unable to carry out daily life and work.

    Measured: The end of Week 8

  4. the change from baseline in epigstric pain syndrome score

    "The dyspepsia symptom scoring criteria" consists of 5 items, with a minimum score of 0 and a maximum of 10 points for each item.

    0 points: asymptomatic; 1-3 points: mild disturbance, mild symptoms, almost no impact on daily life and work; 4-6 points: moderate disturbance, still tolerable, partially affecting daily life and work; 7-10 points: Severe disturbance, unbearable, unable to carry out daily life and work.

    The score for epigastric pain syndrome includes the sum of the scores for mid-upper quadrant pain and mid-upper quadrant burning sensation

    Measured: The end of Week 8

  5. epigastric pain syndrome response rate

    Measured: The end of Week 8

  6. the change from baseline in the total score of TCM

    The TCM Syndrome Scale for Postprandial Distress Syndrome contains two main symptoms, each of which can be evaluated as 0, 2, 4 and 6 points. 6 sub-symptoms, each of which can be evaluated as 0, 1, 2, and 3 points.

    The scale has a minimum score of 0 and a maximum of 30 points, with the higher the score, the more severe the condition.

    Measured: The end of Week 8

  7. the change value of TCM single symptom score from baseline

    The TCM Syndrome Scale for Postprandial Distress Syndrome contains two main symptoms, each of which can be evaluated as 0, 2, 4 and 6 points. 6 sub-symptoms, each of which can be evaluated as 0, 1, 2, and 3 points.

    The scale has a minimum score of 0 and a maximum of 30 points, with the higher the score, the more severe the condition.

    Measured: The end of Week 8

  8. TCM syndrome integral effective rate

    Recovery: Symptoms and signs disappear or basically disappear, and the score reduction rate of the syndrome ≥95%; Effective: Symptoms and signs improved, and the score reduction rate of the syndrome was ≥50%; Ineffective: no significant improvement in symptoms and signs, and the score reduction rate of the syndrome <50%.

    Recovery: Symptoms and signs disappear or basically disappear, and the score reduction rate of the syndrome ≥95%; Effective: Symptoms and signs improved, and the score reduction rate of the syndrome was ≥50%; Ineffective: no significant improvement in symptoms and signs, and the score reduction rate of the syndrome <50%.

    Recovery: Symptoms and signs disappear or basically disappear, and the score reduction rate of the syndrome ≥95%; Effective: Symptoms and signs improved, and the score reduction rate of the syndrome was ≥50%; Ineffective: no significant improvement in symptoms and signs, and the score reduction rate of the syndrome <50%.

    Measured: The end of Week 8

  9. the grade change of TCM single symptom from baseline

    The TCM Syndrome Scale for Postprandial Distress Syndrome contains two main symptoms, each of which can be evaluated as 0, 2, 4 and 6 points. 6 sub-symptoms, each of which can be evaluated as 0, 1, 2, and 3 points.

    The scale has a minimum score of 0 and a maximum of 30 points, with the higher the score, the more severe the condition.

    Measured: The end of Week 8

  10. the proportion of subjects with sustained remission and no exacerbation of single symptoms at 12W compared with 8W

    There are 5 items in the Likert scale, with a minimum score of 1 and a maximum of 7 points for each item. The scale has a minimum score of 0 and a maximum of 35 points, with higher scores and more severe conditions.

    Among them, the subjects selected (1) and (2) are defined as having sustained remission from treatment; Subjects selected (3) and (4) were defined as having no exacerbation of disease; Subjects selected (5), (6), and (7) were defined as having exacerbated disease.

    Measured: The end of Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lianxiaxiaopi Granules and a simulated agent of Lianxiaxiaopi Granules in people with Postprandial Distress Syndrome, run by Tasly Pharmaceutical Group Co., Ltd at 18 sites 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 7 inclusion and 13 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 20 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 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 Peimin Feng, Doctor (18981885791, 76262251@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Postprandial distress syndrome response rate (time frame: The end of Week 8). 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 20 Jan 2026; AzTrials last refreshed its copy on 8 Nov 2026.
