Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of participants classified as responders, defined by excellent or good in the Modified Aronchick scale | On the day of colonoscopy (Day 1) | The efficacy of overall colon cleansing in terms of responders will be graded by a blinded endoscopist using the Modified Aronchick Scale. It 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

|---|---|---|
| Percentage of participants who completed the assigned dose of CLENPIQ among participants in whom nasogastric tube was not utilized to assist with CLENPIQ dosing | From randomization (Day -1) up to second dose of CLENPIQ (Day 1) | A nasogastric tube may be inserted if the participant is likely to fail to drink the prescribed amount of cleanout preparation within the required time. Percentage of participants who completed the assigned dose of CLENPIQ without utilizing nasogastric tube will be reported. |
| Frequency of each category of the Modified Tolerability and Satisfaction Questionnaire: How easy was it for you/the child to drink the bowel cleanout medicine? | On the day of colonoscopy (Day 1) | The tolerability and satisfaction of colon cleansing preparation for colonoscopy will be assessed by the child/ parent(s)/caregiver(s)/guardian(s) using modified tolerability and satisfaction questionnaire. The above question will be answered on a 6-point scale: (1=very easy, 2=easy, 3=okay, 4=difficult, 5=very difficult, 6=do not know). |
| Frequency of each category of the Modified Tolerability and Satisfaction Questionnaire: How did the bowel cleanout medicine taste? | On the day of colonoscopy (Day 1) | The tolerability and satisfaction of colon cleansing preparation for colonoscopy will be assessed by the child/ parent(s)/caregiver(s)/guardian(s) using modified tolerability and satisfaction questionnaire. The above question will be answered on a 6-point scale: (1=very well, 2=well, 3=okay, 4=bad, 5=very bad, 6=do not know). |
| Frequency of each category of the Modified Tolerability and Satisfaction Questionnaire: How often did your/the child's tummy hurt since you/the child started the cleanout? | On the day of colonoscopy (Day 1) | The tolerability and satisfaction of colon cleansing preparation for colonoscopy will be assessed by the child/parent(s)/caregiver(s)/guardian(s) using modified tolerability and satisfaction questionnaire. The above question will be answered on a 6-point scale: (1=never, 2=rarely, 3=sometimes, 4=often, 5=very often, 6=do not know). |
| Frequency of each category of the Modified Tolerability and Satisfaction Questionnaire: How often did you/the child feel fullness in your/the child's tummy since you/the child started the cleanout? | On the day of colonoscopy (Day 1) | The tolerability and satisfaction of colon cleansing preparation for colonoscopy will be assessed by the child/ parent(s)/caregiver(s)/guardian(s) using modified tolerability and satisfaction questionnaire. The above question will be answered on a 6-point scale: (1=never, 2=rarely, 3=sometimes, 4=often, 5=very often, 6=do not know). |
