Official title
A Randomized Study to Assess the Tolerability Profile of Two Concentrations of Liquid Metformin (100 mg/mL and 250 mg/mL) Compared With Standard Metformin Tablets
Overview
This is an open-label, randomized study evaluating the tolerability of two concentrations of liquid metformin formulations (100 mg/mL and 250 mg/mL) compared with standard immediate-release metformin tablets in healthy adult subjects. Each participant will receive single oral doses of study treatments in a randomized sequence. Safety and tolerability will be assessed through adverse event monitoring, gastrointestinal symptom evaluations, vital signs, clinical laboratory tests, and ECGs.
Interventions
- Drug Liquid Metformin 100 mg/mL
A single oral dose of a liquid metformin formulation at a concentration of 100 mg/mL will be administered under fasting conditions in one period of the crossover to assess tolerability and safety. - Drug Liquid Metformin 250 mg/mL
A single oral dose of a liquid metformin formulation at a concentration of 250 mg/mL will be administered under fasting conditions in one period of the crossover to assess tolerability and safety. - Drug Standard Metformin Immediate-Release Tablet
A single oral dose of standard immediate-release metformin tablet(s) will be administered under fasting conditions in one period of the crossover to assess tolerability and safety.
Primary outcome measures
- Incidence of Gastrointestinal Treatment-Emergent Adverse Events (GI TEAEs) [Time frame: From each study dose through 24 hours postdose in each treatment period]
- Severity of Gastrointestinal Treatment-Emergent Adverse Events [Time frame: From each study dose through 24 hours postdose in each treatment period]

Able to provide written informed consent before any study-specific procedures are conducted.
Willing and able to comply with all study requirements, including fasting, dosing restrictions, and safety/tolerability assessments.
Females of childbearing potential must use acceptable contraception as determined by the investigator.
Exclusion criteria
- Known hypersensitivity or contraindication to metformin or any excipients in the study formulations.
History or presence of clinically significant cardiovascular, hepatic, renal, gastrointestinal, endocrine, hematologic, neurologic, or psychiatric disease that, in the investigator's opinion, could interfere with participation or data interpretation.

Positive test for hepatitis B surface antigen, hepatitis C antibody, or HIV.
Positive urine drug screen or positive alcohol breath test at screening or at check-in.
Participation in another clinical trial or receipt of an investigational drug or device within 30 days or 5 half-lives (whichever is longer) before first study dose.
Donation of ≥450 mL of blood, or significant blood loss, within 8 weeks before the first study dose.
Pregnant or breastfeeding females.
Women of childbearing potential not using acceptable contraception.
Any condition or finding that, in the opinion of the investigator, would make the subject unsuitable for the study.
