Efficacy and Safety of LXI-15028 Comparing With Lansoprazole in the Treatment of Duodenal Ulcer

A Multi-center, Randomized, Double-blind, Active-controlled Phase III Clinical Study to Evaluate the Efficacy and Safety of LXI-15028 Compared to Lansoprazole in the Treatment of Duodenal Ulcer in Chinese Patients for up to 6 Weeks

This is a multi-center, randomized, double-blind, double-dummy, parallel-group, active-controlled Phase III clinical study to evaluate the efficacy and safety of LXI-15028 50mg comparing with Lansoprazole 30 mg after the treatment of duodenal ulcer in Chinese patients for up to 6 weeks.

Study Overview

• Status: Completed
• Conditions: Duodenal Ulcer
• Intervention / Treatment: Drug: LXI-15028 50mg group; Drug: Lansoprazole 30mg group

Detailed Description

Screening-eligible subjects will be randomized into LXI-15028 50 mg group or Lansoprazole 30 mg group at Visit 1 at the ratio of 1:1 and receive study treatment continuously for 4 or 6 weeks.Subjects will take the first dose of the investigational drug on the morning of the randomization day or on the next morning of the randomization day, and start to complete the subject's diary from the day of study treatment initiation(Day 1). After 4 weeks treatment, subjects will return to the study institution for Visit 3. For the subjects who achieve endoscopic healing at Visit 3,the study treatment will be terminated.The subjects who fail to achieve endoscopic healing at Visit 3 will receive newly dispensed investigational products for another 2 weeks' treatment and then complete Visit 4.All subjects will receive telephone follow-up (Visit 5) on Day 28 ± 3 after the last dose of the investigational products.

3. Male or female subjects with age ≥18 years and ≤70 years.
4. Subject who is diagnosed as active DU (at least one ulcer, but not more than two ulcers, with the bigger one 0.3-2.0 cm in diameter) by upper gastrointestinal tract endoscopy in the same study institution within 14 days prior to the first dose of investigational drug and is staged as A1 or A2 by using the staging system of Sakita-Miwa.
5. Subject who agrees to use appropriate medical method for contraception during the course of the study (not including women in medically sterile state)

Exclusion Criteria:

1. Subject who had participated in any other clinical study of LXI-15028 previously, or had been treated with any P-CAB drug before.

2. Participation in other clinical study within 4 weeks prior to the first dose of study drug, except for the two following circumstances:

   1. The study which the subject is participating or participated in is a non-interventional study (e.g. observational study or questionnaire survey) and is judged by investigators to have no interference with the efficacy and safety evaluation in the present study;
   2. Subject had signed the informed consent form in that study, but withdrew from that study prior to the start of any treatment.
3. Subject who participates in the planning or conduct of this study.
4. Pregnant or lactating women.
5. Subject who is known to be allergic to the active ingredient or excipient of the investigational drug (including Lansoprazole).

9. Ulcers caused by endoscopic procedures, e.g. post endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) ulcers.
10. Zollinger-Ellison syndrome.
11. History of malignant tumor within 5 years prior to screening (if the subject's basal cell carcinoma or cervical carcinoma in situ has been cured, he/she will be allowed to participate in this study).
12. Subject with history of upper GI surgery (except endoscopic surgery such as resection of benign polyp, etc.).
13. Subject who plans to be hospitalized for receiving selective surgery during the study.
14. Subject with uncontrolled and unstable hepatic, renal, cardiovascular, respiratory, endocrine, hematologic or central nervous system disease as judged by investigators.
15. Subject with history of chronic alcohol consumption [more than 14 units per week, each unit corresponds to 360 mL beer (ABV ≈ 5%) or 45 mL spirit (ABV ≈ 40%) or 150 mL wine (ABV ≈ 12%)] or drug abuse within 5 years prior to screening.
