About this study
Official title: Phase 4, Efficacy and Safety of Sinquanon for Prevention of Antibiotic-associated Diarrhea in Adults in the Out-patient Setting: Prospective, Multicenter, Double-blind, Placebo-controlled Randomized Parallel-arm Clinical Study
The purpose of this study is to evaluate the efficacy of a probiotic, SINQUANON, on the reduction of the occurrence of diarrhea associated with antibiotic use in adults.
Read the detailed description
The study aims to evaluate the efficacy of a specialized multi-strain probiotic, SINQUANON, on the reduction of the incidence of antibiotic-associated diarrhea in adults and to demonstrate the benefit of administering the specialized multi-strain probiotic as a routine add-on to antibiotic therapy on prevention of antibiotic-associated diarrhea in adults who take antibiotics in the outpatient setting.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SinquanonDietary supplement
This probiotic food supplement includes fourteen probiotic bacterial strains of Lactobacillus Spp, Bifidobacterium Spp., Bacillus coagulans, Saccharomyces boulardii, three prebiotics and Vitamin-B complex - B1, B2, B3, B6, B7, B9 in an enterosolvent cellulose capsule. The product includes supplementary substances: maltodextrin and magnesium stearate.
2 capsules once a day during the antibiotic dosing. 1 capsule a day for 14 days following completion of antibiotic dosing.
PlaceboDietary supplement
The placebo product will have the same appearance as the active product and the same composition but without the live bacteria, prebiotics, and vitamin-B complex. 2 capsules once a day during the antibiotic dosing. 1 capsule a day for 14 days following completion of antibiotic dosing.
| Study group | Role | What they receive |
|---|---|---|
| Probiotic | Experimental | During the antibiotic dosing (from 5 to 10 days): 2 capsules once a day 2 hours before or 2 hours after antibiotic administration. 14 days following completion of antibiotic dosing: 1 capsule a day. Receives: Dietary Supplement: Sinquanon |
| Placebo | Placebo comparator | During the antibiotic dosing (from 5 to 10 days): 2 capsules once a day 2 hours before or 2 hours after antibiotic administration. 14 days following completion of antibiotic dosing: 1 capsule a day. Receives: Dietary Supplement: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of Antibiotic-Associated diarrhea (AAD)
The incidence of AAD is defined as the number of subjects who experience at least one day of diarrhea compared to the total number of subjects enrolled in the given treatment arm. AAD is defined as 3 or more loose or liquid stools (types 5-7 according to Bristol Stool Scale [BSS]) over a period of 24 hours.
Measured: By 21+2 days after completion of antibiotic dosing.
Secondary outcomes (5)
Severity of AAD
Investigator will assess AAD severity using the following modified scale defining AAD as: severe: ≥7 unformed/loose/liquid stools; moderate: 5-6 unformed/loose/liquid stools; mild: a change in the stool pattern 3-4 unformed/loose/liquid stools a day. Investigator's assessment will take into consideration the 24-hour period presenting with the worst severity.
Measured: By 21+2 days after completion of antibiotic dosing.
Duration of diarrhea
Number of sequential days with diarrhea. Defined as the time until the first normalization of the stool form according to BSS: presence of one or two sequential normal stools, i.e. "soft and formed" or "hard and formed" - types 1-4 per BSS (or lack of stool) for a period of 24 hours.
Measured: By 21+2 days after completion of antibiotic dosing.
Antibiotic-associated adverse experiences (abdominal pain, bloating, passing gas, nausea)
Presence of abdominal pain, bloating, passing gass, nausea - Yes/No.
Measured: By 21+2 days after completion of antibiotic dosing.
Visual-analogue scale for the gastrointestinal quality of life (VAS-QoL)
Measured via Visual-analogue scale for the gastrointestinal quality of life. The subjects will answer the question: "To what extent the abdominal problems impact your quality of life?" This scale has numerical points from 0 to 100. "100" indicates THE WORST quality of life one can imagine, "0" indicates NO problems and THE BEST quality of life one can imagine.
Measured: By 21+2 days after completion of antibiotic dosing.
Adverse events (AE)
Incidence of mild (for example, self-resolving), moderate (for example, those requiring medical evaluation) and serious AEs (for example, events requiring lasting hospitalization) adverse events.
Measured: By 21+2 days after completion of antibiotic dosing.

Questions about this trial
What is this clinical trial studying?
A study testing Sinquanon in people with Antibiotic-associated Diarrhea, run by Neopharm Bulgaria Ltd. at 3 sites in Bulgaria.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Bulgaria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of Antibiotic-Associated diarrhea (AAD) (time frame: By 21+2 days after completion of antibiotic dosing.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05607056, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Oct 2024.
