E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Chronic intestinal pseudo-obstruction (CIPO) is a rare, severe condition characterized by an impairment of coordinated propulsive activity in the intestinal tract resulting in a clinical picture similar to that of mechanical intestinal obstruction, although in the absence of any lesion occluding the gut. CIPO can be idiopathic, when no primary underlying disorder is demonstrated, or secondary, when related to systemic diseases. |
|
E.1.1.1 | Medical condition in easily understood language |
Chronic intestinal pseudo-obstruction (CIPO) is a rare disease impacting the intestinal motility, potentially invalidating. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this study is to investigate the safety, tolerability and efficacy of velusetrag in improving the symptoms severity associated with CIPO, in subjects with idiopathic CIPO and CIPO secondary to neurodegenerative or demyelinating conditions (e.g., Parkinsonian Syndromes, multiple sclerosis, etc.). |

|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Men or women aged 18-80 years. 2. Subjects with history of chronic idiopathic intestinal pseudo-obstruction or CIPO secondary to neurodegenerative or demyelinating disease. 3. Subjects with estimated oral caloric intake of at least 30% of the daily age- and sex-recommended caloric intake (stage 0, 1 or 2 of the “artificial food need” scale, see 21.3 Appendix 3: Artificial Food Need" (AFN) Scale for CIPO patients). 4. Subjects with at least 2 out of 4 CIPO gastrointestinal symptoms (i.e., abdominal pain, bloating, nausea and vomiting), each of the 2 with a score =3 (on a 0 to 4 scale) collected on the gastrointestinal symptom questionnaire at Day -1 5. Subjects accepting to provide and legally capable of providing free and informed consent to all procedures included in the protocol. 6. All sexually active male participants who are partner of women of childbearing potential must use condom during intercourse until the 90th day after the end of the entire study. 7. All female participants must be: • of non-childbearing potential, i.e.: i) post-menopausal (at least 2 years without spontaneous menses), or ii) surgically sterile (bilateral tubal occlusion, or hysterectomy), or iii) ablation of both ovaries or • of childbearing potential with a negative pregnancy test result at screening and randomization AND agreeing to use a highly effective method of contraception (i.e., with failure rate of less than 1% per year) until the end of the entire study. |
|
E.4 | Principal exclusion criteria |
1. Subjects with primary CIPO or CIPO secondary to other known endocrine/metabolic, autoimmune diseases and neurologic conditions other than neurodegenerative or demyelinating diseases. 2. Subjects with conditions characterized by mechanical intestinal obstruction. 3. Nasogastric tube, gastrostomy tube, or jejunostomy feeding tube in place at randomization or planned throughout the duration of the study, or artificial food need scale stage 3 (“total non-oral nutrition”, see 21.3 Appendix 3: Artificial Food Need" (AFN) Scale for CIPO patients). 4. Presence of untreated clinically relevant thyroid dysfunction or known thyroid dysfunction not well controlled by treatment (e.g., subjects with abnormal thyroid stimulating hormone [TSH], and, if available, triiodothyronine [T3] and thyroxin [T4] levels) deemed clinically significant by the Investigator. 5. Subjects with history of diabetes at screening. 6. Clinically significant ECG abnormalities (e.g., ST segment elevation or depression suggestive of ischemia, partial or complete left bundle branch block [LBBB]) at Screening and randomization. 7. Screening ECG with a QTcF >450 msec in males or >470 msec in females or family history of sudden cardiac death. 8. Subjects requiring a low galactose diet. 9. Hypersensitivity or documented intolerance to lactulose, lactose or any excipient of the lactulose preparation to be used for L-BT. 10. History of sensitivity to velusetrag, or any of the velusetrag or placebo excipients. 11. Use of scopolamine or erythromycin within 2 weeks prior to Screening and/or planned throughout the duration of the study. 12. Use of 5-HT4 receptor agonists (e.g., prucalopride, cisapride, clebopride and cinitapride) within 5 days prior to randomization and/or planned throughout the duration of the study 13. Use of opioids within 8 weeks from screening and/or planned throughout the duration of the study. |

E.5 End points |
E.5.1 | Primary end point(s) |
Change in weekly global gastrointestinal symptoms average index score from start to the end of each treatment period. The weekly global gastrointestinal symptoms average index score is obtained by averaging the scores for each of the 4 symptoms assessed weekly: abdominal pain, bloating, nausea and vomiting. |
