Brief Summary:
Proof of concept study to validate the ability of a capsule device to gather samples from the small bowel for microbiome analysis in adults and to detect dietary changes from simultaneous ingestion of a probiotic.

Condition or disease Intervention/treatment Phase
Proof of Concept Device: Ingestible Capsule Dietary Supplement: Probiotic Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 20 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Use of the Small Intestine Microbiome Aspiration (SIMBA) Capsule to Detect a Dietary Intervention in the Small Intestine
Actual Study Start Date : December 22, 2020
Actual Primary Completion Date : February 24, 2021
Actual Study Completion Date : February 24, 2021

Arm Intervention/treatment
Experimental: Single Arm
Participant swallows and retrieves capsule in stool before and after ingestion of a probiotic. Capsule and stool samples are analyzed for presence of probiotic strain and compared to baseline.
Device: Ingestible Capsule
Participants will swallow capsule and undergo X-rays to establish transit

Dietary Supplement: Probiotic
Participants will swallow a probiotic capsule and the sample collection capsule at the same time to establish concentration of strain in small intestine.

Primary Outcome Measures :
  1. Bacterial density count [ Time Frame: 7 days ]
    density count of probiotic strain compared between capsule and stool sample (CFU/ml)
