Clinical Trial Summary

The present pilot study is aimed to obtain preliminary data on the effect of three ascending oral dose levels of nepadutant on the relief of symptoms associated with feeding intolerance. In addition, the assessment of drug exposure (PK assessment) will provide additional information on the dose-effect relationship, thus supporting the dose selection and dosing schedule in the future studies.

Description:

Feeding intolerance is a transient neuro-developmental phenomenon affecting 25% to 40% of infant and toddler, with a peak at 6 weeks of age. Feeding problems include mainly vomiting, slow feeding, refusal to eat and colic.

Current non pharmacological interventions (e.g. message, restriction in maternal diet in breast-feeding infants) and pharmacological treatments (simethicone, antimuscarinic drugs and antiacids) are largely unsatisfactory.

Nepadutant is postulated to have a therapeutic effect in infant colic since it reverts exaggerated intestinal motility and sensitivity induced by different stimuli through the activation of neurokinin-2 receptors, without interferring on the on physiological gastrointestinal transit.

This phase IIa study is designed to test in each participant infant two out of three oral doses of nepadutant in order to measure its blood levels, safety and efficacy with each dose level to be given for 7 concecutive days.

The experimental clinical phase encompasses the following periods:

• Screening period (no study medication), lasting approximately 7 days prior to randomization

• Treatment period, lasting fourteen days (7 days fore each dose)with once daily administration

• A safety follow-up visit, approximately four weeks after start of treatment.

Primary	The Absolute Differences of I-GERQ-R Total Score at V3 (End of First Week of Treatment) Respect to the Baseline (V2).	Results obtained at V2 serve as baseline values for the assessment of effects at V3 (i.e. end of first week of treatment).; Infant Gastroesophageal Reflux Questionnaire Revised (I-GERQ-R ), with a minimum-maximum score of 0-42 (minimum for diagnosis >15). The higher values reflect worse outcome. The questionnaire comprised 12 items as questions quantifying aspects of regurgitation (3 questions), crying (3 questions), feeding refusal (2 questions), apnea/cyanosis (2 questions), hiccups and arching. Questions with 4 possible options have a score ranging from 0 to 3; questions with 5 possible options have a score ranging from 0 to 4.; The scores of each item are summed, so the total score is presented.
