Not Applicable

Completed

Conditions: Irritable Bowel Syndrome With Diarrhea

Interventions: Dietary Supplement: PX0612
Dietary Supplement: Di-Calcium Phosphate

Registration Number: NCT02431533

Lead Sponsor: Pharmabiotix Inc

Brief Summary: IBS is a disorder of movement in the gut. People who have IBS may have diarrhea, constipation, or alternating bouts of both. IBS is not caused by injury or illness. Often the only way doctors can diagnose it is to rule out other conditions through testing.

Detailed Description: Probiotics, particularly Bifidobacterium infantis, Sacchromyces boulardii, Lactobacillus plantarum and combination probiotics may help regulate how often people with IBS have bowel movements. Probiotics may also help relieve bloating from gas. Research is continuing to determine which probiotics are best to treat IBS.

PX0612

PX0612 is a probiotic which is composed of the following ingredients contained in a veggie capsule, being one dose:

Bacillus coagulans 200 million colony forming units 16.0mg Bacillus subtilis 100 million colony forming units 4.8mg Enterococcus faecium 100 million colony forming units 0.6mg Fructo-oligosacharride a nutrient for the packaged product 600.0mg Total 621.4 mg Bacillus coagulans is a non-pathogenic, Gram positive, spore forming bacteria that produces lactic acid. Though not normally found in the gut. Bacillus coagulans strains have been used as general nutritional supplements and agents to control constipation and diarrhea in humans and animals.

Arm && Interventions

Group	Intervention	Description
Probiotic PX0612	PX0612	PX0612 is a probiotic contained in a veggie capsule.
Di-Calcium Phosphate	Di-Calcium Phosphate	Patients in the 'placebo' group will receive the placebo capsules. The main ingredient in the placebo capsule is Di-Calcium Phosphate

Primary Outcome Measures

Name	Time	Method
Change in the Bowel Movements (Stool Frequency) Between the 'Intervention' Group and the 'Placebo' Group Over the Study Period.	Baseline (days 1-14) compared to Weeks 10 and 11 of treatment (days 78-91)	For each patient stool frequency was measured as a number of bowel movements per day. To compare stool frequency before and after the treatment, the average for the first 2 run-in weeks (day 1 - day 14) and the last 2 weeks (day 78 - day 91) was calculated. A higher mean score indicates a better outcome, a greater reduction in bowel movements/day and is a positive change. Placebo group- min: -.43 max: 1.43 Study group- min: -.43 max: 1.50

Secondary Outcome Measures

Name	Time	Method
Differences in Upper Gastrointestinal Symptoms Between the 'Intervention' Group and the 'Placebo' Group Over the Study Period.

A higher mean value indicates a greater reduction in heartburn, better outcome. Analog Scale from 0-4 was used by participants to rate upper GI symptoms of heartburn (0= no heartburn, 4= incapacitating). Placebo group- Min: -2.00 Max: 3.00 Treatment group- Min: -2.00 Max: 2.00
The Difference in Change of Postprandial Fullness Severity	Baseline compared to Week 12	Differences Between the 'Intervention' Group and the 'Placebo' Group Over the Study Period. Mean change in postprandial fullness between baseline and week 12 between the two groups. A higher mean value indicates a greater reduction in a postprandial fullness, better outcome. Analog Scale from 0-4 was used by participants to rate upper GI symptoms of postprandial fullness (0= no postprandial fullness, 4= incapacitating postprandial fullness). Placebo group- Min: -1.00 Max: 2.00 Treatment group- Min: -1.00 Max: 2.00
Upper Gastrointestinal Symptom of Nausea	Baseline and Week 12	Differences Between the 'Intervention' Group and the 'Placebo' Group Over the Study Period. Mean change in nausea between baseline and week 12 between the two groups. A higher mean value indicates a greater reduction in nausea, better outcome.

Differences in Upper Gastrointestinal Symptoms- Vomiting Between the 'Intervention' Group and the 'Placebo' Group Over the Study Period.	Baseline compared to Week 12	vomit scale used was from 0-4, the higher the number, the worse the outcome Mean change in vomiting between baseline and week 12 between the two groups. A higher mean value indicates a greater reduction in vomiting, better outcome. Analog Scale from 0-4 was used by participants to rate upper GI symptoms of vomiting(0= none, 4= incapacitating). Placebo group- Min: 0 Max: 0 Treatment group- Min: -3.00 Max: 0
Differences in Abdominal Pain/Discomfort Between the 'Intervention' Group and the 'Placebo' Group Over the Study Period.	Baseline (days 1-14) compared to Weeks 10 and 11 of treatment (days 78-92)	Outcome measure is the mean change of abdominal pain, on a scale of 0-4 (0= no pain, 4= incapacitating pain), between baseline and Weeks 10 and 11. A larger change in average abdominal pain indicates a greater reduction in mean abdominal pain score, better outcome. Min=-.067 for treatment group Min= -.99 for placebo group Max= 1.14 for treatment group Max= 1.63 for placebo group The total number of participants analyzed in each group differs as a result of the number of participants that either withdrew or were withdrawn in the study. Data were analyzed and compared for participants that completed the study.
Differences in Upper Gastrointestinal Symptoms- Early Satiety	Baseline compared to Week 12	Differences Between the 'Intervention' Group and the 'Placebo' Group Over the Study Period. Change in rate of early satiety on a scale from 0-4 (higher the score, the worse the outcome) Mean change in early satiety between baseline and week 12 between the two groups. A higher mean value indicates a greater reduction in early satiety, better outcome. Analog Scale from 0-4 was used by participants to rate upper GI symptoms of early satiety (0= none, 4= incapacitating). Placebo group- Min: -2.00 Max: 1.00 Treatment group- Min: -2.00 Max: 2.00
Differences in Stool Frequency Between the 'Intervention' Group and the 'Placebo' Group Over the Study Period.	Baseline (days 1-14) compared to Weeks 10 and 11 of treatment (days 78-92)	Number of stools/day
Changes in the Patient's Assessment of Their Quality of Life Using Short Form(SF)-36 Health Survey PCS (Physical Component Score)	Baseline compared to Week 12 (end of study)	Differences in quality of life phusical component score using SF-36 between the 'intervention' group and the 'placebo' group over the study period. Baseline PCS scores were compared to the end of the study time point. The mean difference between the 2 time points was measured. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability. Scoring is based on software program. Placebo group- Min: -16.16 Max: 6.25 Treatment group- Min: -16.42 Max: 5.46 The total number of participants analyzed in each group differs as a result of the number of participants that either withdrew or were withdrawn in the study. Data were analyzed and compared for participants that completed the study.
Upper Gastrointestinal Symptoms of Prolonged Digestion	Baseline compared to Week 12	Differences Between the 'Intervention' Group and the 'Placebo' Group Over the Study Period. Mean change in prolonged digestion between baseline and week 12 between the two groups. A higher mean value indicates a greater reduction in prolonged digestion, better outcome. Analog Scale from 0-4 was used by participants to rate upper GI symptoms of prolonged digestion (0= none, 4= incapacitating). Placebo group- Min: -2.00 Max: 1.00 Treatment group- Min: -1.00 Max: 3.00

A higher mean outcome indicates a greater reduction in loose stool/diarrhea (better outcome). Bristol Stool Chart (1=severe constipation to 7 =severe diarrhea) was the scale used for measurement. The participant reported outcomes were averaged at above time points for comparison. Min for placebo group: -.70 Max for treatment group: 2.57 Max for placebo group: 1.88 The total number of participants analyzed in each group differs as a result of the number of participants that either withdrew or were withdrawn in the study. Data were analyzed and compared for participants that completed the study.
