E.3 | Principal inclusion criteria |
1. Patient is a man or woman aged 18 to 65 years, inclusive, at screening. 2. Patient who started opioid treatment and is on a stable dose for the last 4 weeks 3. Patient experiencing opioid induced constipation. 4. Patient is experiencing upper gastrointestinal symptoms beside opioid induced constipation with an average composite GCSI-DD score of ≥2 during the 14 days before randomization. 5. Medications taken for the treatment of allergies, chronic medical conditions, and migraine headaches can be taken during this study. Patients on a stable dose of one antidepressant for at least 3 months will be allowed to participate in the study. Habitual use of benzodiazepines is permitted. 6. Female subjects must either be: a. postmenopausal, defined as 52 years or older and amenorrheic for at least 2 years at screening, b. surgically sterile (have had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy), c. abstinent, or d. if sexually active, be practicing an effective method of birth control such as hormonal prescription oral contraceptives, progesterone implants or injections, contraceptive patch, intrauterine device, or male partner with a vasectomy. 7.

E.4 | Principal exclusion criteria |
1. Patient has a history of inflammatory or immune-mediated GI disorders including inflammatory bowel disease (ie, Crohn’s disease, ulcerative colitis), celiac disease and functional bowel disorder. 2. Patient has a history of diverticulitis. 3. Patient has a history of intestinal obstruction, stricture, toxic megacolon, GI perforation, gastric banding, bariatric surgery, adhesions, ischemic colitis, or impaired intestinal circulation (eg, aortoiliac disease). 4. Patient has any of the following surgical history: a. Any abdominal surgery within the 3 months prior to screening; b. Subject has a history of major gastric, hepatic, pancreatic, or intestinal surgery (appendectomy, hemorrhoidectomy, or polypectomy more than 3 months post-surgery are allowed). 8.

Patient has a history of malignancy within 5 years before screening (except squamous and basal cell carcinomas and cervical carcinoma in situ). 12. Patient has abnormal thyroid function test as confirmed by thyroid-stimulating hormone <0.3 mcIU/mL or ≥5 mcIU/mL at screening. However, patients who are clinically euthyroid due to thyroid supplement are candidates for the study. 13. Patient has received an investigational drug or used an investigational medical device within 14 days prior to screening, or is currently enrolled in an investigational study. 14. Patient is pregnant or breastfeeding. 15.
