About this study
Official title: Multicenter, Prospective, Comparative, Randomized Controlled Clinical Trial to Evaluate the Performance and the Safety of Promelaxin® Micro-enemas Vs. Macrogol 4000 Per os in the Treatment of Functional Chronic Constipation in Children Aged Between 6 and 48 Months.
The study is aimed at the efficacy and safety evalutation of the study treatments through a 2-weeks study period and the subsequent follow-up-
Read the detailed description
This multicenter, prospective, randomized, controlled trial will be conducted on 120 infants-children with a diagnosis of chronic functional constipation according to the definition of Criteria of Rome III. The enrolled subjects will be randomized according to an electronically generated randomization list in 2 groups: one group will receive micro-enemas of Promelaxin® (Group A) while the second group will receive Macrogol 4000 per os (Group B) . Children will receive the dedicated treatment for two weeks and then undergo a follow-up period of a maximun of 6 weeks.
The hypothesis is that the protective micro-enema will help achieving regular evacuation by its local antinflammatory non-pharmacological action. This hypothesis is based on the finding that local anal inflammation can cause functional constipation due to discomfort and pain during evacuation or by influencing reflexes.
- Conditions
- Chronic Functional Constipation
- Being tested
- micro-enema with Promelaxin, Macrogol 4000
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
micro-enema with PromelaxinDevice
Also called Melilax
The intervention has a lubricating, protective action on the anus and rectum and a balanced osmotic action which elicits the evacuation reflex.
Macrogol 4000Drug
Also called Paxabel
Stool softener
| Study group | Role | What they receive |
|---|---|---|
| micro-enema with Promelaxin | Experimental | 2,5 g, 5 g or 2X5 g (calculated considering patient age) have to be administered daily (in the evening) for one week, once every other day for the second week and as needed for the following 6 weeks Receives: Device: micro-enema with Promelaxin |
| Macrogol 4000 | Active comparator | One/Two sachets of the study treatment has to be solubilized in 50mL of water and then administered daily. The administration should take place in the morning (the first sachet or in the event that only one sachet/day should be administered) and in the evening (second sachet). Receives: Drug: Macrogol 4000 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Improvement of constipation evaluated as a reduction of the typical symptoms of chronic functional constipation
Treatment should be considered as successful if the child will show, at Visit 3, 3 or more defecations per week associated with an increase of 1 or more defecations versus baseline.

A Phase 4 study testing micro-enema with Promelaxin and Macrogol 4000 in people with Chronic Functional Constipation, run by Aboca Spa Societa' Agricola at 4 sites in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 May 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Improvement of constipation evaluated as a reduction of the typical symptoms of chronic functional constipation (time frame: day 14). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02751411, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2020; AzTrials last refreshed its copy on 8 Nov 2026.
