Primary

MeasureTime frameDescription
Percentage of Participants Defined by Excellent or Good in the Aronchick ScaleOn the day of colonoscopyAronchick scale is a 4-point scale that grades colon cleansing as Excellent (\>90% of mucosa seen, mostly liquid stool, minimal suctioning needed for adequate visualization), Good (\>90% of mucosa seen, mostly liquid stool, significant suctioning needed for adequate visualization), Fair (\>90% of mucosa seen, mixture of liquid and semisolid stool, could be suctioned and/or washed) or Inadequate (\<90% of mucosa seen, mixture of semisolid and solid stool which could not be suctioned or washed). The participant is considered to be a responder if overall colon cleansing is excellent or good on this 4-point scale.

Secondary

MeasureTime frameDescription
Number of Participants With Adverse EventsUp to 33 days after colonoscopyAn adverse event (AE) is defined as any untoward medical occurrence in a participant taking part in a clinical trial. Proportion of participants with AE are presented.
Number of Participants With Abnormal Findings in Laboratory TestsFrom up to 42 days prior to colonoscopy, at the day of colonoscopy, and up to 7 days post colonoscopyProportion of participants with abnormal findings in laboratory tests are presented.
Number of Participants With Abnormal Findings in Physical ExaminationFrom up to 42 days prior to colonoscopy, on the day of randomization, and at the day of colonoscopyComplete physical examination was conducted at screening and directed physical examinations at other time-points. Directed physical examinations are presented.
Number of Participants Who Took the Assigned Dose for Colon CleansingApprox. 1 day (From the day before colonoscopy to the day of colonoscopy)The proportion of participants who took the assigned dose of Prepopik® was assessed.
Number of Participants in Each Category of the Subject's Tolerability and Satisfaction Questionaire1 day of colonoscopySubject's Tolerability and Satisfaction Questionnaire consists of three questions. Question (Q)1 was How easy was it to drink the bowel cleanout medicine? and Q2 was How did the bowel cleanout medicine taste?. Q3 had five subparts namely: 1. How often did your tummy hurt since you started the medicine? and 2. How often did you feel fullness in your tummy, since you started the cleanout? and 3. How often did you wake up last night and 4. How often did you feel sick to your stomach (nausea) since you started the cleanout?' and 5. How much were you bothered by going to the washroom since you started the cleanout? Satisfactory was defined as a response of 1 (Very Easy) or 2 (Easy) on Q1 and a response of 1 (Very Well) or 2 (Well) on Q2. Tolerable was defined as a response of 1 (Never) or 2 (Rarely) to the five subparts specified in Q3.

ArmCount
Prepopik® ½ Sachet x 2 (9-12 Years)
Prepopik® (sodium picosulfate 10 mg; magnesium oxide 3.5 g and anhydrous citric acid 12 g) reconstituted with water was administered in Split Dose method. The first dose was administered between 5:00 PM and 9:00 PM on the day before the colonoscopy procedure. The second dose was given on the next day, at least 6 hours after the first dose and approximately 5 hours before but no more than 9 hours prior to the colonoscopy. Day Before method was the alternative method if Split Dose was not appropriate.

Outcome results

Primary

Percentage of Participants Defined by Excellent or Good in the Aronchick Scale

Aronchick scale is a 4-point scale that grades colon cleansing as Excellent (\>90% of mucosa seen, mostly liquid stool, minimal suctioning needed for adequate visualization), Good (\>90% of mucosa seen, mostly liquid stool, significant suctioning needed for adequate visualization), Fair (\>90% of mucosa seen, mixture of liquid and semisolid stool, could be suctioned and/or washed) or Inadequate (\<90% of mucosa seen, mixture of semisolid and solid stool which could not be suctioned or washed). The participant is considered to be a responder if overall colon cleansing is excellent or good on this 4-point scale.

Time frame: On the day of colonoscopy

Population: The primary efficacy analysis was based on the intention-to-treat (ITT) analysis set, which included all participants who were randomized.

Number of Participants Who Took the Assigned Dose for Colon Cleansing

The proportion of participants who took the assigned dose of Prepopik® was assessed.

Time frame: Approx. 1 day (From the day before colonoscopy to the day of colonoscopy)

Population: The safety analysis set included participants who received at least one dose of the trial medication. Participants were analyzed according to actual treatment received. One of the participant randomized to Prepopik® ½ sachet x 2 (9-12 years) received Prepopik® 1 sachet x 2 (9-12 years) instead (n=17).

Number of Participants With Abnormal Findings in Physical Examination

Complete physical examination was conducted at screening and directed physical examinations at other time-points. Directed physical examinations are presented.

Time frame: From up to 42 days prior to colonoscopy, on the day of randomization, and at the day of colonoscopy

Population: The safety analysis set included participants who received at least one dose of the trial medication. Participants were analyzed according to actual treatment received. One of the participant randomized to Prepopik® ½ sachet x 2 (9-12 years) received Prepopik® 1 sachet x 2 (9-12 years) instead (n=17).

Number of Participants With Adverse Events

An adverse event (AE) is defined as any untoward medical occurrence in a participant taking part in a clinical trial. Proportion of participants with AE are presented.

Time frame: Up to 33 days after colonoscopy

Population: The safety analysis set included participants who received at least one dose of the trial medication. Participants were analyzed according to actual treatment received. One of the participant randomized to Prepopik® ½ sachet x 2 (9-12 years) received Prepopik® 1 sachet x 2 (9-12 years) instead (n=17).
