New probiotic bug passes first safety test in small human trial
NCT ID NCT07285317
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tested whether a new probiotic bacterium called Phascolarctobacterium faecium is safe and well-tolerated when taken daily as a pill for 15 days. Twenty adults—some with normal weight and some with overweight or early blood sugar issues—participated. Researchers monitored digestive symptoms, blood tests, and overall health to check for side effects. The study does not aim to treat any condition, only to see if the bacterium is safe enough for future research.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Phascolarctobacterium faecium (a probiotic bacterium taken as a pill)
What this could lead to
If this bacterium is safe and well-tolerated, it could pave the way for larger studies exploring whether it helps improve metabolic health in people with obesity or type 2 diabetes.
What could go wrong
This is a very early, small Phase 1 trial with only 20 participants. It only tests safety and tolerability for 15 days, so it cannot show any health benefits. Mild digestive side effects like bloating or gas are possible.
