Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The overall study duration consists of a total of 12 weeks consisting of 8 weeks of intervention (treatment) and an additional 4 weeks as an observation period (no treatment). Participants will be provided with 5 x 250ml bottles in total, 3 bottles at Baseline and 2 bottles at Week 4, containing the investigational medicine. Participants will carefully measure out and orally consume 10 mLs of the investigational product SVT-1B149, twice daily for 8 Weeks. Each 10 mL dose of SVT-1B149 contains 1.5 x 10^10 (15 billion) colony forming units (CFU) of bacterial species. 10 mLs of product will be consumed in the morning and evening with food, with the participants required to record each dose taken. Participants will record their adherence to the intervention in a participant diary, along with all bowel movements, any adverse events and any concomitant medications taken during the study period. At the end of Week 4 participants will return to the clinic for assessment and to review their study diary. Participants will be required to return the 2 empty medication bottles to account for any missed doses. They will be provided two new bottles of study medication. The participants will be provided a second diary for the following 4 weeks and they will continue to record their adherence to the intervention, along with all bowel movements, any adverse events and any concomitant medications taken during the study period. At the end of the 8 Weeks, participants will return the remaining 3 medication bottles to the study coordinator to account for missed doses, if any. The participants will be provided a third diary for the following 4 Weeks and they will continue to record any adverse events in the diary following the study period. They will not consume the study medication during this 4 week period.

Outcomes
Primary outcome [1] 324444 0
To evaluate the safety and tolerability of twice daily oral consumption of SVT-1B149 in adult participants confirmed to have functional constipation, but who are otherwise healthy. Assessed by incidence of treatment emergent adverse events (TEAEs), discontinuations due to adverse events (AEs) determined from participant diaries and systemic tolerability based on vital signs, - Blood Pressure and Heart Rate measured by using a sphygmomanometer, - Temperature measured with a thermometer - Respiratory rate counted by the Investigator based on number of times the chest rises in 1 minute with participant in Supine position. Examples of known/possible adverse reactions/events: Human safety and efficacy studies have not yet been conducted with the specific combination of bacteria present in SVT-1B149, however their individual safety for human consumption is well recognised and documented. Each species has a Risk Group 1 Classification in that they are not associated with disease in healthy adults and all have been granted the Qualified Presumption of Safety (QPS) status by the European Food Safety Authority (EFSA). Potential adverse events that participants may experience include mild gastrointestinal symptoms including abdominal discomfort, bloating, flatulence and/or nausea.

Summary
Brief summary
The aim of this study is to evaluate safety and tolerability of SVT-1B149 as a treatment for chronic functional constipation together with preliminary efficacy. The treatment consists of carefully selected bacterial species. Bacteria are naturally found in the digestive tract and are a research focus for their important role in many conditions related to gut health. Bacteria play an important role in the function of the immune system, digestive health, inflammation and have anti-microbial properties. Several research studies have found treatment with beneficial bacteria to relieve constipation and related symptoms. This study will help determine how safe and effective SVT-1B149 is as a stand-alone therapy in treating constipation and reducing symptoms.
