E.3 | Principal inclusion criteria |
Initial inclusion criteria (before baseline metabolic balance study) 1. Signed informed consent for this trial prior to any trial specific assessment 2. Male and female subjects with SBS-IF and CIC (at least 28% [Cummings, 1973] and no colostomy), receiving PS, secondary to surgical resection of the small intestine with <200 cm from duodenojejunal flexure, based on available medical/surgical records and with the latest intestinal resection being at least 12 months prior to Screening 3. Subject considered stable with regard to PS and weight. Stability is defined as a subject meeting all the following criteria in the 3 months preceding screening: a) Weight change (increase or decrease) ≤5% b) PS volume change not exceeding 25% c) PS energy content change not exceeding 25% d) Actual PS usage in terms of volume and content matches prescribed PS (±10%) 4. Parenteral support requirement of at least 2 days per week as assessed at Screening 5. Willingness to undergo either a colonoscopy or colonography and have any identified polyps removed via colonoscopy 6. Willingness to remain in clinic for metabolic study on three occasions for 5 days 7. Adhere to an individual pre-defined drinking menu and urine measurements during the 48-hour measuring periods 8. No planned restorative surgery or major intestinal surgery (more than 10% intestinal resection or surgery that changes anatomy group, i.e., stoma or CIC), in the trial period 9. Age ≥18 years at Screening 10.Women of childbearing potential must agree to practice effective contraception and to use a highly effective method of contraception during the trial and for 4 weeks after the EOT Visit. Such methods include one of the following: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal); progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable); intrauterine device; intrauterine hormone-releasing system; bilateral tubal occlusion; or a vasectomized partner. To be considered sterilized or infertile, females must have undergone surgical sterilization (bilateral tubectomy, hysterectomy or bilateral ovariectomy) or be post-menopausal (defined as at least 12 months amenorrhea, without an alternative medical cause, may be confirmed with follicle-stimulating hormone test if there is doubt). Women who do not engage in heterosexual intercourse during the trial and 4 weeks after the EOT Visit will be allowed to join the trial without contraception following a thorough discussion with the Investigator to determine if this is feasible for the subject. The following methods are not considered acceptable methods of contraception: calendar, ovulation, symptothermal, post-ovulation methods, withdrawal (coitus interruptus), spermicides only, and lactational amenorrhea method 11.Male subjects with a female partner of childbearing potential must commit to practice methods of contraception (e.g., condoms or a vasectomy) and abstain from sperm donation during the trial and for 2 weeks after the EOT Visit. Their partners if they are women of childbearing potential must agree to practice contraception and to use a highly effective method of contraception during the trial and for 4 weeks after the EOT visit. Such methods include: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal); progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable); intrauterine device; or an intrauterine hormone-releasing system Dosing inclusion criteria (after baseline metabolic balance study completion and before the first dose) 12.Average fecal wet weight excretion of ≥500 g/day during the baseline metabolic balance study 13.Average urine volume is ≥0.8 L and ≤2.5 L per day during baseline metabolic balance study |
