Brief Summary:

This is one multi-center, randomized, double-blind, parallel-group, placebo controlled Phase III clinical study to evaluate the efficacy and safety of LXI-15028 50 mg in treatment of non-erosive reflux disease in Chinese patients for 4 weeks.

Screening-eligible subjects will be randomized into LXI-15028 50mg group or placebo group at Visit 2 (Day 0) according to the ratio of 1:1 and receive study treatment for 4 weeks. They will start to take the investigational products in the following morning of Visit 2 (Day 1) and start to complete the subject's diary from the day of study treatment initiation. After 2 weeks of study treatment, subjects will return to the study site and complete Visit 3, after which receive study treatment for another 2 weeks and then complete Visit 4. On the day of Visit 4, subjects will not take any drug. All the subjects will be followed up by phone (Visit 5) at Day 28±3 after the last dose of study medication.

Arm Intervention/treatment
Experimental: LXI-15028 50mg group Drug: LXI-15028
The investigational products are administrated orally, once in the morning every day, and each dose includes one tablet of investigational products (LXI-15028 50mg active agent or placebo). If the investigational product is not taken in the morning, subjects can take it before 6:00 p.m. on the same day. The duration of treatment is 4 weeks.

Primary Outcome Measures :
  1. Resolution of main symptoms [ Time Frame: 4 weeks after receiving oral doses ]
    Resolution rate of main symptoms (heartburn, regurgitation) at Week 4: percentage of patients with complete resolution of main symptoms (for consecutive 7 days) at Week 4. Note: At Week 4, Reflux Disease Questionnaire (RDQ) (item a, b, e, f) is used to evaluate all main symptoms during previous consecutive 7 days. Complete resolution is defined as the main symptoms are completely resolved and do not occur.


Secondary Outcome Measures :
  1. Resolution of main symptoms [ Time Frame: 2 week after receiving oral doses ]
    Resolution rate of main symptoms (heartburn, regurgitation) at Week 2: percentage of patients with complete resolution of main symptoms (for consecutive 7 days) at Week 2. The main symptoms are evaluated using RDQ.

  2. Symptom improvement [ Time Frame: 4 weeks after receiving oral doses ]
    Change of Reflux Disease Questionnaire (RDQ) score (including severity score and frequency score) of each post-treatment visit from baseline;Symptom assessment based on subject diary;

  3. Life quality improvement [ Time Frame: 4 weeks after receiving oral doses ]
    Change of Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) score of each post-treatment visit from baseline.

  • Subject who is able to understand and follow the protocol requirements and agrees to participate in all the study visits.
  • Male or female subjects with age ≥ 18 years.
  • Having experienced heartburn (burning or pain behind the breastbone) and regurgitation (acid taste in the mouth and discomfort movement of materials upwards from the stomach) symptoms at least three months prior to screening.
  • Having experienced heartburn and regurgitation within 7 days prior to screening, with the frequency and severity in symptom assessment meeting at least one of the following items:

    • Mild heartburn for at least 2 days, with regurgitation;
    • Mild regurgitation for at least 2 days, with heartburn;
    • Moderate or more severe heartburn for at least 1 day, with regurgitation;
    • Moderate or more severe regurgitation for at least 1 day, with heartburn. (Note: To be determined by using the RDQ [item a, b, e, f] completed by subject.) And the RDQ symptom assessment before randomization (Visit 2) still meets the above criteria.
  • Within 14 days before study initiation, the subject has been confirmed with no mucosal damage through upper gastrointestinal endoscopy based on Los Angeles (LA) classification. And non-erosive reflux disease is clinically diagnosed by the investigator.
  • Subject who agrees to use appropriate medical method for contraception from the signature of the informed consent form to 28 days after the last dose of study medication (not including women in medically sterile state):

    • Women under medically sterile state can participate in this study, for example, postmenopausal state (spontaneous amenorrhea at least for 12 months), post hysterectomy, post bilateral salpingectomy and post bilateral oophorectomy;
    • Appropriate medical contraceptive measures include intrauterine device, physical barrier (male condom, female condom), subcutaneous implant, sustained release contraceptive injection, bilateral salpingectomy and bilateral vasoligation. Note: Use of oral contraceptives is not allowed during the course of study, and dual contraceptive methods are recommended, as to ensure no occurrence of pregnancy during the course of study.
