This study aims to assess the clinical efficacy, safety and tolerance of a new formula containing a prebiotic and a mix of probiotics in the specific population of infants suffering from functional constipation through a superiority, double-blind, randomized, placebo-controlled trial.
The study comprises a selection period of 1 week where the eligibility of the infant to participate in the study will be evaluated. Once his/her participation is confirmed, the tested formula will be compared to a standard formula during a 2-month study period followed by an optional follow-up period of 2 months where only the tested formula will be used.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| IT formula | Experimental | The test product (IT formula) is an infant formula based on cow's milk proteins containing a high level of lactose, a prebiotic, a high concentration of magnesium and a mix of probiotics. |
|
| Standard formula | Placebo Comparator | The control product is a standard infant formula based on cow's milk proteins containing usual lactose and magnesium content, no prebiotic nor probiotic. |

|---|---|---|---|---|
| new infant formula | Dietary Supplement | New formula containing a prebiotic and a mix of probiotics, randomly assigned to infants during a 2-month period and allocated to all infants during the optional open-label follow-up period of 2 months. |
| Measure | Description | Time Frame |
|---|---|---|
| Hard stool consistency or painful defecation | Proportion of hard or painful stools per total number of spontaneous bowel movements by participant. A spontaneous bowel movement is defined as described in outcome 2. Stool consistency will be evaluated based on the Brussels Infant and Toddler Stool Scale (BITSS). BITSS is a reliable instrument to assess stools of non-toilet trained children. It consists of color photographs of nappies containing stools from infants and toddlers categorized as hard, formed, loose, or watery (Huysentruyt et al., 2019). The consistency and painful defecation of each stool will be assessed by parents at Day 30. | 30 days |
| Measure | Description | Time Frame |
|---|---|---|
| Total and spontaneous defecation frequency | Spontaneous bowel movement is defined as a bowel movement not produced by the use of rescue medication. Stools occurring within 24h after the use of rescue medication will not be considered spontaneous. If 2 stools occur within less than 1 hour, only 1 stool will be considered (Koppen et al., 2018). Defecation frequency will be assessed by parents by recording the time of each stool during the week preceding each visit. |

The allocation of the formula to each infant is drawn according to a randomization list developed using a software by the clinical research organization in charge of statistics and known only to him until the blind is lifted, i.e. after the statistical analysis. A 1:1 double-blind randomisation will be computer-generated by block (in each center).
| Standard formula | Dietary Supplement | Standard infant formula containing no prebiotic nor probiotic, randomly assigned to infants during a 2-month period followed by an optional open-label follow-up period of 2 months with the new infant formula |
|
|
| 30, 60, 90 and 120 days |
| Stool consistency | Parents will record the consistency of every stool the week preceding each visit as described in the outcome 1 using the BITSS scale (Brussels Infant and Toddler Stool Scale) which consists of 4 stools consistency categories (hard, formed, loose, or watery ; Huysentruyt et al., 2019) | 30, 60, 90 and 120 days |
| Painful defecation | Painful defecation will be evaluated by parents for each stool during the week preceding each visit (Yes/No). | 30, 60, 90 and 120 days |
| Excessive stool retention | "Excessive stool retention" is defined as "the infant withholding stools". It will be evaluated by parents at each visit (presence/absence). | 30, 60, 90 and 120 days |
| Large diameter stools | Large diameter stools will be assessed by parents at each visit using the picture of the largest stool in the BITSS as an example of the large diameter stool (presence/absence). | 30, 60, 90 and 120 days |
| Treatment success | Treatment success is defined as no longer meeting the modified Rome IV criteria for functional constipation, i.e. the treatment will be considered as a success if the infant does not meet more than one of the following criteria per week during the week preceding each visit:
| 30, 60, 90 and 120 days |
| Rescue medication use | The frequency of use, type and dosage of rescue medication will be assessed by parents during the whole study. | 30, 60, 90 and 120 days |
| Weight | Weight will be expressed in kg and in z scores according to the World Health Organization (WHO) Child Growth Standards. | 30, 60, 90 and 120 days |
| Height | Height will be expressed in cm and in z scores according to the WHO Child Growth Standards. | 30, 60, 90 and 120 days |
| Head circumference | Head circumference will be expressed in cm and in z scores according to the WHO Child Growth Standards. | 30, 60, 90 and 120 days |
| BMI | BMI will be expressed in value and z scores according to the WHO Child Growth Standards. | 30, 60, 90 and 120 days |
| Adverse events | Any untoward medical condition occurring during the study in an infant receiving study products regardless of a causal relationship with the product or not will be considered an adverse event and reported as such. This definition includes events occurring from the moment the parents have signed the Informed Consent form (day -7) up until the study end (or early termination). | Through study completion, i.e. 67 days or 127 days if participation to the optional follow-up period |
| Nutritional status | Nutritional status will be assessed based on the evaluation of specific blood biological markers (albumin, creatinine, urea, hemoglobin, sodium, potassium, chloride). | 0 and 60 days |
| Crying time | Daily crying duration will be assessed by parents on 3 days in the week preceding each visit. | 30, 60, 90 and 120 days |
| Regurgitations | The number of regurgitation episodes, the volume of regurgitation and regurgitation severity will be assessed by parents on 3 days in the week preceding each visit. Regurgitation severity will be assessed through the Vandenplas score ranging from 0 (=less than 2 regurgitation episodes / day) to 6 (=regurgitation of the complete volume after each feeding). | 30, 60, 90 and 120 days |
| Sleep quality | Sleep quality will be evaluated by parents at each visit by asking them if their child's sleep was quiet or agitated. | 30, 60, 90 and 120 days |
| Sleep time satisfaction | Sleep time satisfaction will be evaluated by parents at each visit (Yes/No). | 30, 60, 90 and 120 days |
| Parents' quality of life (QoL) | Parents' QoL will be assessed based on a questionnaire adapted from the Parental Opinions of Pediatric Constipation (POOPC) scale (Silverman et al., 2015). Questions from this scale were chosen based on their relevance to constipated infants. This questionnaire is composed of 4 items, i.e. Burden/Worry, Family, Treatment and Social. Each question is scored on a scale of 1 (=Strongly Disagree) to 5 (=Strongly Agree) with higher scores indicating that infant's constipation greatly affects parents' QoL. The total score is calculated by summing the scores of all individual question, ranging from 15 to 75 where a score of 15 indicates that infant's constipation does not affect parents' QoL whereas a score of 75 indicates that parents' QoL is extremely affected by infant's constipation. | 30, 60, 90 and 120 days |
| Parents' satisfaction | Parents' adequate relief will be assessed at each visit (Yes/No). | 30, 60, 90 and 120 days |
| Gut microbiota composition | Gut microbiota composition will be analyzed by 16S rRNA gene sequencing from stool samples. | 0 and 60 days |
| Short-chain fatty acids (SCFAs) | SCFAs will be measured in stool samples by gas chromatography/mass spectrometry (GC/MS). | 0 and 60 days |
