Outcome Measures

Primary Outcomes (3)

  • Tolerability of ISOThrive using Patient Assessment of Constipation Quality of Life Questionnaire (PAC-QOL)

    PAC-QOL a validated questionnaire which measures subject experience over the prior 2 weeks, includes a total of 28 items in 4 subscales: worries and concerns (11 items), physical discomfort (4 items), psychosocial discomfort (8 items), and satisfaction (5 items). Higher scores of PAC-QOL indicate more negative effects of constipation on the quality of life. This study will assess whether subjects with constipation tolerate ISOThrive by measuring the differences in baseline and post-intervention score using PAC-QOL. The score taken at the end of Week 1 of the Screening Phase will be compared to the scores at the end of Week 2 and Week 4 of the Tolerability Phase. Any difference in scores between Week 2 and Week 4 of the Tolerability Phase will also be compared. Tolerability is defined as the difference between the baseline score and the post-intervention score at Week 4 of the Tolerability Phase. It must be equal to or less than the baseline score.

    5 weeks

  • Tolerability of ISOThrive using Patient Assessment of Constipation Symptoms (PAC-SYM)

    PAC-SYM is a validated 12 item constipation symptom questionnaire assessing symptoms over the prior 2 weeks. Sub-scores and total score vary from 0 to 4. All scores are given equal weight. A lower score indicates less symptom severity. This study will assess whether subjects with constipation tolerate ISOThrive by measuring the differences in baseline and post-intervention score using PAC-SYM. The score taken at the end of Week 1 of the Screening Phase will be compared to the scores at the end of Week 2 and Week 4 of the Tolerability Phase. Any difference in scores between Week 2 and Week 4 of the Tolerability Phase will also be compared. Tolerability is defined as the difference between the baseline score and the post-intervention score at Week 4 of the Tolerability Phase. It must be equal to or less than the baseline score.

    5 weeks

  • Tolerability of ISOThrive using the Bristol Stool Scale (BSS)

    This study will assess whether subjects with constipation tolerate ISOThrive by measuring differences in pre and post-intervention scores using the BSS and bowel movement frequency. Electronic BSS diaries will be recorded daily. The BSS is an indicator of colonic transit time using a seven-point scale. Type 1 and 2 indicate hard stool; type 3, 4 and 5 show looser (ideal) stool; and type 6 and 7 indicate stool that is too loose. Tolerability is primarily defined as an increase in the frequency of bowel movements. Tolerability is secondarily defined as improvement in quality, a larger percentage of scores of 3, 4, and 5. Any difference in scores between weeks 1, 2, 3, and 4 of the Tolerability Phase will also be compared. Tolerability is defined as follows: average week 4 stool quality must be equal to or improved (equal to or more scores of 3, 4 and 5) relative to baseline, and average week 4 bowel movement frequency must be equal to or more than baseline frequency.

Tolerability Arm

OTHER

This is a single arm study. All subjects will receive the test material. The test material is ISOThrive. It is an approximately 90% pure maltosyl-isomalto-oligosacchride (MIMO) prebiotic syrup produced by bacterial fermentation/bio-conversion of sucrose and maltose. It is taken 1g daily for 30 days.

Dietary Supplement: ISOThrive Prebiotic Nectar
