AIM-MET: AI-Guided Microbiome-Targeted Nutrition for Glycemic Improvement in Type 2 Diabetes

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Type 2 Diabetes, Diabetes Mellitus Type 2

In brief

AIM-MET is a randomized clinical study testing whether a fixed microbiome-targeted nutritional product can improve blood sugar control in adults with type 2 diabetes when used in addition to usual stable diabetes treatment. The study will compare the active nutritional product with a matching placebo over 24 weeks. The product was designed using artificial intelligence before the study began, but the same fixed formulation will be used for all participants assigned to the active group. Artificial intelligence will not be used during the study to make individual treatment decisions, adjust dosing, or personalize the product. The main question is whether participants receiving the active product have a greater reduction in HbA1c, a standard marker of average blood sugar levels, from the start of the study to Week 24 compared with participants receiving placebo. The study will also evaluate early blood sugar changes, fasting glucose, body weight and waist measurements in participants with baseline BMI of at least 25.0 kg/m2, safety, hypoglycaemia events, patient-reported outcomes, and gut microbiome features. This is a 100-participant proof-of-concept study intended to estimate the size of the treatment signal, safety, feasibility, and parameters needed for a future larger confirmatory trial.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Adults aged 18 to 65 years.
• Established diagnosis of type 2 diabetes mellitus documented in the medical record, supported by American Diabetes Association diagnostic criteria on at least one prior occasion.
• HbA1c 6.8% to 8.2% at screening, measured by an NGSP-certified central laboratory assay; confirmed on a repeat sample if discordant with prior records or if the screening value is at the upper or lower boundary.
• Body mass index 18.5 to 40.0 kg/m2 at screening.
• Stable background glucose-lowering therapy for at least 3 months before randomization, restricted to metformin, a DPP-4 inhibitor, and/or an SGLT2 inhibitor, either alone or in combination.
• Documented body-weight stability, defined as no more than +/-5% or +/-3 kg, whichever is smaller, self-reported body-weight change during the 3 months before screening.
• Willing and able to provide written informed consent.
• Willing and able to comply with trial visits, study product use, fasting blood sampling, stool sampling, and the study assessment schedule.
• Willing to receive standardized lifestyle counselling during the 24-week blinded period and to maintain stable background diabetes management as clinically directed.
• No systemic antibiotic use within 8 weeks before randomization.
• No probiotic, prebiotic, synbiotic, or postbiotic supplement use within 8 weeks before randomization.
• Stable hypertension, dyslipidaemia, and stable thyroid replacement therapy are permitted if medication has been initiated and the dose unchanged for at least 3 months before randomization.

You may not qualify if…

• Type 1 diabetes, latent autoimmune diabetes of adults, pancreatogenic diabetes, maturity-onset diabetes of the young, gestational diabetes as the current diagnosis, or any non-type-2 form of diabetes.
• HbA1c less than 6.8% or greater than 8.2% at screening.
• Current use of GLP-1 receptor agonists or GLP-1/GIP co-agonists, or use within 12 months before randomization.
• Current use of basal, prandial, or premixed insulin, or any insulin use within 6 months before randomization.
• Current use of sulfonylureas or meglitinides, or use within 3 months before randomization.
• Current use of anti-obesity pharmacotherapy or use within 6 months before randomization, including orlistat, naltrexone/bupropion, phentermine/topiramate, or other agents with a primary anti-obesity indication.
• Recurrent severe hypoglycaemia or hypoglycaemia unawareness.
• Planned initiation or dose escalation of glucose-lowering medication, anti-obesity medication, or systemic corticosteroids during the 24-week trial period in the judgment of the treating clinician.
• History of bariatric surgery at any time.
• Gastrointestinal surgery other than appendectomy or uncomplicated cholecystectomy.
• Active inflammatory bowel disease, coeliac disease, microscopic colitis, chronic pancreatitis, malabsorption syndrome, or chronic severe gastrointestinal disease likely to affect absorption or trial adherence.
• Acute gastroenteritis within 4 weeks before randomization.
• Colonoscopy bowel preparation within 12 weeks before randomization.
• Faecal microbiota transplantation within 12 months before randomization.
• Active or recent malignancy within 6 months, except adequately treated non-melanoma skin cancer.
• Stage 3b to 5 chronic kidney disease, defined as estimated glomerular filtration rate less than 45 mL/min/1.73 m2.
• Decompensated liver disease or Child-Pugh class B/C.
• ALT or AST greater than 3 times the upper limit of normal at screening, unless judged clinically insignificant and approved by the investigator.
• Known or suspected haemoglobinopathy that materially distorts HbA1c measurement or haemoglobin variant known to interfere with the central laboratory assay.
• Blood transfusion, significant blood loss greater than 250 mL, or erythropoiesis-stimulating agent therapy within 3 months before randomization.
• Untreated overt thyroid disease, or thyroid medication initiation or dose change within 3 months before randomization.
• Use of systemic corticosteroids within 4 weeks before randomization.
• Use of immunosuppressive medication or biologic/immunomodulatory therapy within 5 half-lives before randomization.
• Pregnancy or lactation; women of childbearing potential not willing to use effective contraception during the 24-week blinded period.
• Severe psychiatric illness or cognitive impairment that may compromise informed consent, safety, or adherence.
