FOCUSED Trial Summary

This trial is studying if gut bacteria from healthy donors can help people with OCD. It will use stool analysis and SIMBA capsules to measure changes in the gut microbiome.

Who is the study for?
This trial is for adults with OCD who haven't had enough improvement from their current SSRI treatment. They must have been on a stable dose for at least 12 weeks and not be suicidal or diagnosed with certain digestive diseases like IBD, Crohn's, Ulcerative colitis, or Celiac disease. They can't be immune-suppressed, pregnant, breastfeeding, planning to get pregnant during the study, regularly taking antibiotics/prebiotics/probiotics, have swallowing disorders or meet criteria for substance use/eating disorder/schizophrenia.Check my eligibility
What is being tested?
The trial tests fecal microbiota transplantation (FMT) using capsules containing gut bacteria from healthy donors to treat OCD. It explores the connection between gut health and brain function by comparing stool analysis and SIMBA capsule results—a device that samples fluid from the small intestine—to see how FMT might benefit those with OCD.See study design
What are the potential side effects?
While specific side effects are not listed here due to the novel nature of this intervention in treating OCD via FMT capsules plus SIMBA capsules; potential risks may include gastrointestinal discomforts such as bloating or cramps.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What potential adverse effects could arise from the combination of FMT capsule and SIMBA Capsule?

"The existing evidence on FMT capsule + SIMBA Capsule's safety is sufficient to warrant a score of 2. This Phase 2 trial has not yet produced any data regarding the medication's efficacy, but there are multiple studies indicating its safety profile."

Answered by AI

Does the study requirements include elderly participants aged 85 and over?

"This clinical trial has a narrow age range of 18 to 65. However, there are additional studies dedicated specifically for those under 18 and over 65 respectively; 20 trials and 67 trials in total."

Answered by AI

Are new participants still being sought for this scientific endeavor?

"As per clinicaltrials.gov, the recruitment for this medical trial has closed since the last changes made to it were on February 7th 2023. Nonetheless, there are currently 106 other trials actively searching for participants."

Answered by AI

What are the desired outcomes of this experiment?

"The primary outcome metric for this Nimble Science Ltd.-sponsored study, evaluated over a 0-13 week period of time, is the Toronto Side Effects Scale (TSES). Additionally, secondary assessments will be conducted to gauge Global function/overall improvement; these include The General Anxiety Disorder-7 scale (GAD-7), Positive and Negative Affect Schedule (PANAS) as well as Patient Health Questionnaire-9(PHQ9)."

Answered by AI

Am I eligible to enroll in this clinical experiment?

"This clinical trial is enrolling 20 individuals between the ages of 18 and 65 who have been diagnosed with Obsessive Compulsive Disorder (OCD). To be eligible, patients must also meet the following requirements: a confirmed OCD diagnosis, at least 12 weeks of SSRI treatment prior to baseline assessment, and evidence that their current medication has not adequately managed symptoms."
