A Clinical Trial to Evaluate The Effects of Semaglutide and Empagliflozin Combined to Automated Insulin Delivery on Diabetes Control in Adults Living With Type 1 Diabetes

Q: Who can participate in NCT06894784?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

Q: How do I contact the trial site for NCT06894784?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Q: Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.

Semaglutide And Empagliflozin Combination Therapy Added To Automated Insulin Delivery In Adults With Type 1 Diabetes (SEMPA)

A Clinical Trial to Evaluate The Effects of Semaglutide and Empagliflozin Combined to Automated Insulin Delivery on Diabetes Control in Adults Living With Type 1 Diabetes (NCT06894784) is a Phase 3 interventional studying Diabetes Type 1, sponsored by McGill University Health Centre/Research Institute of the McGill University Health Centre. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

The goal of this clinical trial is to learn if Empagliflozin and Semaglutide, individually and combined, added to Automated Insulin Delivery (AID) works to improve time-in-range in adults living with Type 1 Diabetes. It will also evaluate the safety of Empagliflozin and Semaglutide in this context. The primary hypothesis of this study is : \- The combination therapy of semaglutide and empagliflozin will increase time-in-range compared to placebo when added to AID therapy. The secondary hypotheses are : * The combination therapy of semaglutide and empagliflozin will increase time-in-range compared to semaglutide alone when added to AID therapy. * The combination of semaglutide and empagliflozin will increase time-in-range compared to empagliflozin alone when added to AID therapy. In this study, the research team will compare Empagliflozin and Semaglutide to a placebo (a look-alike substance that contains no drug) to see if they improve time-in-range. This study has four groups: Group 1: semaglutide injection + empagliflozin tablet. Group 2: semaglutide injection + placebo tablet. Group 3: placebo injection + empagliflozin tablet. Group 4: placebo injection + placebo tablet. This is a 2x2 factorial crossover study. This means that all participants will undergo both injection intervention (placebo and semaglutide) arms. Within each injection arm, participants will take both tablets (placebo and empagliflozin). By the end of the study, every participant will have taken part in each study group.

What Stage of Research Is This?

Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For Diabetes Type 1, Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 36 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

The inclusion criteria at the time of enrollment are: - Males and females aged 18 or older. - Clinical diagnosis of T1D for at least one year. - Use of AID system for at least three months. - Body Mass Index (BMI) ≥ 23 kg/m2. The exclusion criteria are: - Use of GLP1-RA within one month of admission. - Use of SGLT2i within two weeks of admission. - Planned or ongoing pregnancy. - Breastfeeding. - Severe hypoglycemic episode within three months of admission (defined as an event where blood glucose levels were \< 4.0 mmol/L, resulting in seizure, loss of consciousness, or the need to present to the emergency department). - Diabetic ketoacidosis episode within six months of admission. - History of acute pancreatitis, chronic pancreatitis, or gallbladder disease. - Personal or family history of medullary thyroid cancer or multiple endocrine neoplasia type 2. - Severe impairment of renal function with an eGFR \< 30 mL/min/1.73 m2 within four months of admission. eGFR will be computed using the CKD-EPI method. - Clinically significant diabetic retinopathy or gastroparesis, as per the investigator's judgement. - Bariatric surgery within six months of admission. - A serious medical or psychiatric illness that would likely interfere with participation in this study, as per the investigator's judgement. - Inability or unwillingness to comply with safe diabetes management practices, as per the investigator's judgment. Always talk to your doctor about whether this trial is right for you.
