- Biofarma
- Brief Summary
This is a double blind, randomized, placebo-controlled study. One-hundred subjects are randomized to receive either YOVIS or placebo over a period of 10 days.
The purpose is to determinate the efficacy of the treatment in subjects treated with antibiotic therapy, by measuring occurrence of Antibiotic Associated Diarrhoea (AAD) from baseline to the end of the observation period (28±2 days)
- Detailed Description
AAD is defined as clinically unexplained diarrhea that occurs in connection with antibiotic administration. Any antibiotic could potentially cause AAD, but broad-spectrum antibiotics that predominantly target anaerobes and are poorly absorbed, such as clindamycin, cephalosporins (cefixime and ceftriaxone), and amoxicillin-clavulanate, have a higher AAD incidence (Turck D, 2003). It has been reported that the highest rates of AAD in 650 pediatric cases were associated with amoxicillin/clavulanate (23%), penicillin A or M (11%) and erythromycin (16%).
In the present trial, adult population already under antibiotic therapy with ampicillin/amoxicillin, cephalosporins and clindamycin, will be selected, in order to capture the highest possible diarrhea events, with a limited number of subjects.
YOVIS, the Investigational Food Supplement (IFS), is an oral formulation (capsules) containing definite mix of live probiotics already marketed by Alfa-Sigma as food supplement since September 2017.
Placebo is an oral formulation of inert capsules. Placebo and YOVIS are identical in shape, size, colour and taste.
One-hundred (100) subjects will be randomized to receive either YOVIS or placebo (1:1) over a period of 10 days.
In case all inclusion/exclusion criteria are met, the subject will be randomized at the baseline visit to one of two masked trial treatments. Further phone contacts are scheduled on day 10±2 and day 21±2, a final visit at site is scheduled on day 28±2.
The primary objective of this study is to assess, versus placebo, the efficacy of a 10 days treatment with YOVIS in preventing the incidence of AAD in subjects under antibiotic therapy.

Group Intervention Description Placebo Placebo Placebo is an oral formulation of inert capsules. it is administered to 50 patients 10 consecutive days (1 capsule once daily) with a drop of water, preferably without food. Yovis Capsules Yovis Capsules YOVIS, the Investigational Food Supplement (IFS), is an oral formulation (capsules) containing definite mix of live probiotics already marketed by Alfa-Sigma as food supplement since September 2017. it is administered to 50 patients 10 consecutive days (1 capsule once daily) with a drop of water, preferably without food.
- Primary Outcome Measures
Name Time Method Efficacy of YOVIS in preventing the incidence of AADD in subjects under antibiotic therapy 10 days - 21 days - 28 days The primary objective of this study is to assess, versus placebo, the efficacy of a 10 days treatment with YOVIS in preventing the incidence of AAD in subjects under antibiotic therapy. The incidence of diarrhea in the treatment group will be compared to placebo in the time frame of 28 days.
- Secondary Outcome Measures
Name Time Method Evaluation of duration and severity of gastrointestinal symptoms 28 days the cumulative severity of each symptom
Global Patient's self-reported acceptance at the end of study 28 days Global patient's acceptance to the treatment will be evaluated at the end of study visit, referred to the whole period, as bad, good, fair, excellent
Assessment of acceptability, safety and satisfaction grade of YOVIS versus placebo 10 days Patient satisfaction will be evaluated at the end of treatment. The clinician will ask the patient his satisfaction grade compared to her expectation, in a 5-point scale: Not at all Satisfied," "Partly Satisfied," "Satisfied," "More than Satisfied," "Very Satisfied," numbering 1 to 5 as an interval scale.
Severity and duration of AAD Time Frame: 28 days Cumulative severity of antibiotic-associated diarrhea (AAD): sum of the values (obtained by transformation of Bristol stool form types) of all stools during days with diarrhea (transformation of Bristol scale types is defined: type 1 to 4 = 0; type 5 = 1; type 6 = 2 and type 7 = 3) diarrhea within the observation period
Effects of YOVIS, versus placebo, at each visit on the overall health status 10-21-28 days assessed trough questions on the general well-being and through physical examination during visits. Questionnaire on the Gatrointestinal syntoms. each question minimum value is 0 (no pain at all) to 10 (maximum intensity of pain)
Impact of bowel habits on QoL 10-21-28 days assessed trough a 6-item questionnaire self-compiled by the subject at each visit. Quality of Life Questionnaire is compiled. 6 questions from minimum value of 0 (no impact) to 10 (maximum impact) on the quality of life
Global acceptability (investigator) at the end of study 28 days Global investigator acceptance to the treatment will be evaluated at the end of study visit, referred to the whole period, as bad, good, fair, excellent
