About this study
Official title: A Phase 1, Open-label, Randomized, Three-period, Crossover Study to Evaluate Pharmacokinetic Interaction Between Bexagliflozin Tablets and Metformin, Glimepiride, or Sitagliptin in Healthy Subjects
The purpose of this study is to examine the drug-drug interaction in your body when given the study drug, bexagliflozin, with three commonly used ant-diabetic medications, metformin, glimepiride or sitagliptin. The study will also evaluate how safe the study drug is and how well the study drug is tolerated when taken with metformin, glimepiride or sitagliptin.
Read the detailed description
A total of 54 healthy subjects were enrolled and assigned to one of three groups of eighteen. Each group participated in one of three open-label, randomized, three treatment period, crossover studies:
- Group 1: Bexagliflozin/metformin drug-drug interaction (DDI)
- Group 2: Bexagliflozin/glimepiride DDI
- Group 3: Bexagliflozin/sitagliptin DDI For each Group, every subject received a single dose of bexagliflozin tablet, 20 mg, alone, a single dose of an oral hypoglycemic agent (OHA) (1000 mg metformin, 2 mg glimepiride, or 100 mg sitagliptin) alone, and the combination of both (bexagliflozin tablet and OHA) alternately in a crossover fashion, with three treatment periods separated by a washout period of at least 7 days. Within each Group, subjects were randomized to one of six treatment sequences in an equal ratio.
To prevent hypoglycemia, subjects assigned to Group 2 (bexagliflozin/glimepiride DDI) received approximately 300 mL of a solution containing 50 g of glucose with study medication at the time of dosing, as well as approximately 75 mL of a solution containing 12.5 g of glucose every 15 minutes for 4 hours post-dose.
For each treatment period in Group 1 (bexagliflozin/metformin DDI) and Group 2 (bexagliflozin/glimepiride DDI), subjects were admitted to the clinic on the day before dosing and stayed in the clinic until 48 h post-dose. For Group 3 (bexagliflozin/sitagliptin DDI), subjects stayed in the clinic until 72 h post-dose.
For all Groups, blood samples for PK analysis were collected in each period prior to dosing (pre-dose) and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose. For Group 3, PK blood samples were also collected at 60 and 72 h post-dose. Plasma concentrations of bexagliflozin and OHAs were determined by validated liquid chromatography tandem mass spectrometry (LC MS/MS) assays.
Urine samples for PD analysis were collected in 12 h intervals. For all Groups, urine samples were collected pre-dose (-12 to 0 h) and post-dose at 0 to 12 h, 12 to 24 h, 24 to 36 h, and 36 to 48 h. For Group 3, additional samples at 48 to 60 h and 60 to 72 h post-dose were collected.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Bexagliflozin, Metformin and Glimepiride in people with Type2 Diabetes Mellitus, run by Theracos at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 22 Jul 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cmax (Maximum Observed Plasma Concentration) (time frame: Up to 72 hours). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jul 2021.
