Brief Summary:
A pilot study to explore the metabolic effect and safety of a 3-week course of therapy with MET-3 in obese subjects

Condition or disease Intervention/treatment Phase
Obesity Biological: MET-2 Early Phase 1

Detailed Description:
This is an open label, single center, uncontrolled pilot study of 20 participants; each group will receive a different dose of MET-3. Each group will have 4-6 females, 4-6 participants with BMI 30.0-34.9 kg/m² and the remainder with BMI 35-39.9 kg/m.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 20 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: The study design is open label, single center, uncontrolled pilot study of 20 participants divided into 2 groups of 10; each group will receive a different dose of MET-3. Each group will have 4-6 females, 4-6 participants with BMI 30.0-34.9 kg/m² and the remainder with BMI 35-39.9 kg/m.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I, Open-Label, Single-Centre Study of the Safety and Efficacy of Microbial Ecosystem Therapeutics (MET)-3 in Obese Human Subjects
Actual Study Start Date : October 1, 2018
Estimated Primary Completion Date : September 1, 2019
Estimated Study Completion Date : September 1, 2019

Arm Intervention/treatment
Experimental: Lower BMI
Use of MET-2 in subjects with BMI of 30.0 to 34.9
Biological: MET-2
Ingestion of a novel human microbiome preparation

Experimental: Higher BMI
Use of MET-2 in subjects with BMI of 35 to 39.9
Biological: MET-2
Ingestion of a novel human microbiome preparation

Primary Outcome Measures :
  1. Effect of MET-3 on the Incremental Area under the glucose curve (2 hrs) in obese subjects [ Time Frame: Treatment week 6 ]
    The area under the glucose curve in obese subjects will be measured 2 hours after a 75 g oral glucose challenge. This measurement will be made at baseline and then again after 6 weeks of treatment with MET-3.

Secondary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events [ Time Frame: Period beginning at enrollment and continuing through to end of treatment phase (week 6) ]
    Adverse Events,Complete blood count (CBC), aspartate transaminase (AST), alanine aminotransferase (ALT), Alkaline phosphatase (ALP), bilirubin, urea, amylase, creatinine and electrolytes
