What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

Colonoscopy
| Study group | Role | What they receive |
|---|---|---|

| 2L PEG | Active comparator | Not described Receives: Procedure: Endoscopy |
| 2L sodium picosulfate | Active comparator | Not described Receives: Procedure: Endoscopy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Bowel cleansing
Boston Bowel Preparation Score (BBPS), a 10-point scale assessing bowel preparation after all cleansing maneuvers are completed by the endoscopist. Each region of the colon receives a "segment score" from 0 to 3 and these segment scores are summed for a total BBPS score ranging from 0 to 9. Therefore, the maximum BBPS score for a perfectly clean colon without any residual liquid is 9 and the minimum BBPS score for an unprepared colon is 0.
Measured: 1 year
Secondary outcomes (2)
Treatment related adverse events
Number of Participants with symptomatology related to intervention in each arm of the study
Measured: 1 year
Preparation Tolerability: total volume of solution finally taken by the patient
Evaluation of total volume of solution finally taken by the patient
Measured: 1 year

Who may be eligible to take part?
The sponsor lists 2 inclusion and 6 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 23 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. 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.
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?
Bowel cleansing (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 23 Jul 2021; AzTrials last refreshed its copy on 29 Oct 2026.
