What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline to Week 30 in HbA1c

    This analysis included all Week 30 assessment values available.

    Measured: Baseline to Week 30

Secondary outcomes (5)
  1. Number of Participants With HbA1c <7.0%

    Participants who had no available assessment for HbA1c <7% at Week 30 were considered as non-responders.

    Measured: Week 30

  2. Change From Baseline to Week 30 in Fasting Plasma Glucose (FPG)

    This analysis included all Week 30 assessment values available.

    Measured: Baseline to Week 30

  3. Change From Baseline to Week 30 in Body Weight

    This analysis included all Week 30 assessment values available.

    Measured: Baseline to Week 30

  4. Number of Participants With At Least One Hypoglycemic Events (Documented Symptomatic Hypoglycemia <3.0 mmol/L [<54 mg/dL], Severe Hypoglycemia)

    Documented symptomatic hypoglycemia was an event during which typical symptoms of hypoglycemia were accompanied by a measured plasma glucose concentration of <54 milligrams per deciliter (mg/dL) (<3.0 mmol/L). Severe hypoglycemia was an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions.

    Measured: Baseline up to Week 30

  5. Number of Hypoglycemic Events (Documented Symptomatic Hypoglycemia <3.0 mmol/L [<54 mg/dL] and Severe Hypoglycemia) Per Participant-Year

    Documented symptomatic hypoglycemia was an event during which typical symptoms of hypoglycemia were accompanied by a measured plasma glucose concentration of <54 mg/dL (<3.0 mmol/L). Severe hypoglycemia was an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions.

    Measured: Baseline up to Week 30

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Efpeglenatide SAR439977 and Background therapy: Metformin alone or in combination with SU in people with Type 2 Diabetes Mellitus, run by Sanofi at 48 sites in 3 countries.

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 5 inclusion and 16 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: stopped early, as of the sponsor's last update on 2 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 48 sites in United States, China, Taiwan. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 2 Dec 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?

Change From Baseline to Week 30 in HbA1c (time frame: Baseline to Week 30). 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 2 Dec 2021.
