Brief Summary:
An open-label, single centre, randomised, cross-over study to examine the effect of ulimorelin on the pharmacokinetics of midazolam after repeat dose administration of ulimorelin in healthy volunteers.

Condition or disease Intervention/treatment Phase
Digestive System Disorders Drug: Midazolam Drug: Ulimorelin Phase 1

Detailed Description:

Ulimorelin is a first-in-class new chemical entity. It is a ghrelin agonist with gastroprokinetic activity being developed as an intravenous therapy to be used in the treatment of gastrointestinal (GI) hypomotility disorders such as post-operative ileus (POI) and gastroparesis.

POI is a transient disruption of co-ordinated bowel motility that contributes to patient morbidity, discomfort and prolonged recovery times. POI most commonly occurs after abdominal surgery and annually, POI is the main determinant of length of hospital stay after major abdominal surgery and a factor in patient hospital re-admissions, increased healthcare resource use and cost, and decreased patient satisfaction. Current strategies to attenuate POI are aimed at enhanced recovery after surgery (ERAS) or "fast track". These are multimodal care protocols designed to reduce the impact of external and internal factors on POI duration. Recently, fewer complications and a quicker return to work and normal activities for patients who have had ERAS programmes implemented have been reported. In spite of these strategies only up to 20% of subjects undergoing partial bowel resection recover GI function within 72 hours after surgery.

Arm Intervention/treatment
Experimental: Midazolam
Those subjects to receive Treatment A will receive a single dose of midazolam on Day 1 and will be discharged from the study unit on Day 2, at least 30 hours after midazolam dosing.
Drug: Midazolam
Single oral administration on Day 1 or Day 5
Experimental: Ulimorelin
Those subjects to receive Treatment B will receive once daily ulimorelin on Days 1 to 5. Midazolam will be administered on Day 5 with the last dose of ulimorelin and subjects will be discharged from the study unit on Day 6, at least 30 hours after midazolam dosing.
Drug: Ulimorelin
Intravenous infusion of 480 micrograms/kg on Days 1 to 5
Other Name: TZP101

Primary Outcome Measures :
  1. AUC(0 to infinity) of midazolam [ Time Frame: Pre-(midazolam)dose and 15, 30, 45 mins and 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 16, 24 and 30 hours post dose ]
  2. Cmax of Midazolam [ Time Frame: Pre-(midazolam)dose and 15, 30, 45 mins and 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 16, 24 and 30 hours post dose ]

  7. Female volunteers must be postmenopausal (for at least one year and confirmed by serum follicle stimulating hormone (FSH) at screening), surgically sterile, practising true sexual abstinence, or must use two highly effective methods of contraception (defined as a failure rate of less than 1% per year when used consistently and correctly) throughout the study until after post-study medical as follows: contraceptive implants, injectables, oral contraceptives, some intrauterine devices (IUDs), vasectomised partner and / or barrier method (condom or occlusive cap) with spermicidal foam/gel/film/cream/suppository.
  8. Hormonal and IUD methods of contraception must be established for a period of three months prior to dosing and cannot be changed or altered during the study.
  9. Females of childbearing potential must have a negative serum pregnancy test at screening (β-hCG) and a negative urine pregnancy test at check-in for each period.
  10. Sexually active male volunteers must use condoms with their partners throughout the study and for 90 days after completion of the study in addition to their partner's normal mode of contraception.
  11. Male volunteers must not donate sperm during the study and for 90 days after completion of the study.
  12. Must be willing to consent to have data entered into The Over Volunteering Prevention System (TOPS).
  13. The volunteer's primary care physician must confirm that there is nothing in their medical history that would preclude their enrolment into this clinical study.
