AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults aged 21 to 75 with type 2 diabetes for at least 3 months, taking stable diabetes pills, to test ultrasound on blood sugar control.

Age
21 to 75 years
Sex
Men and women
Disease stage
Type 2 diabetes for at least 3 months. HbA1c above 7.0% (53 mmol/mol) and below 10% (86 mmol/mol). BMI from 18 to 40.0 kg/m2.
Earlier treatment
Must be on a stable dose of diabetes pills (metformin, sulfonylureas, meglitinides or thiazolidinediones) and not due for a higher dose. Cannot be on insulin, DPP-4 inhibitors or GLP agonists.
Biomarker or test result
HbA1c above 7.0% (53 mmol/mol) and below 10% (86 mmol/mol) on a local lab test.

Main reasons for not taking part

  • Type 1 diabetes, or insulin, DPP-4 inhibitor or GLP agonist use
  • Advanced diabetes complications, heart disease or heart rhythm problems
  • Implanted pacemaker, defibrillator or nerve stimulator, or history of seizures
  • Kidney disease or liver disease, or a positive test for hepatitis B, hepatitis C or HIV
  • Pregnancy or breastfeeding

Who can take part

  • Male or female subjects with a diagnosis of type 2 diabetes ≥ 3 months
  • Age ≥ 21 and ≤ 75 years
  • Currently on a stable treatment regimen of oral anti-diabetic drugs and not currently prescribed for medication escalation. Oral anti-diabetic drugs are limited to one or more of the following:; Metformin; Sulfonylureas; Meglitinides; Thiazolidinediones
  • HbA1c > 7.0% and < 10% by local laboratory analysis
  • Body Mass Index (BMI) ≥ 18 to ≤ 40.0 kg/m2
  • Considered generally healthy upon completion of medical history, physical examination and biochemical investigations as judged by the Principal Investigator
  • Female subjects must be non-pregnant and non-lactating and have a negative serum pregnancy test at screening and before the ultrasound session
  • Ability to provide written informed consent

Who cannot take part

  • History or current diagnosis with T1DM or T2DM subjects on insulin, DPP-4 inhibitors, GLP agonists
  • A subject who is already indicated for medication escalation of their current diabetic therapy
  • Invasive cardiovascular procedure, such as coronary artery bypass graft surgery (CABG), or angioplasty/percutaneous coronary intervention (PCI) within 6 months of screening
  • Subjects with a history or presence of any psychiatric disorder that, in the opinion of the Principal Investigator, might confound the results of the trial or pose additional risk in administering the investigational product to the subject
  • History of any major surgery within 3 months prior to screening
  • Any nerve stimulation study or implanted stimulator, including previously or currently implanted vagus nerve stimulator, previously or currently implanted spinal cord stimulator, other implanted electronic medical device, such as implanted pacemaker or cardioverter/ defibrillator (AICD) or history of seizures
  • Participation in an investigational study within 30 days prior to dosing or 5 half-lives within the last dose of the investigational product given during the investigational study, whichever is longer
  • Thyroid hormone use is not allowed unless medication is given on a stable dose for at least 3 months prior to screening
  • History of any active infection, incl. COVID19 (as ruled out by negative PCR test), except mild viral disease, such as common cold, within 30 days prior to screening
  • Donation or loss of > 500 mL of blood or blood product within 2 months prior to screening
  • An abdominal ultrasound scan or exam within 1 month prior to screening and/or any pre-planned ultrasound examinations during the study, or the need to participate in any unplanned outside ultrasound procedures during study
  • Use of the agents listed in Prohibited Medications Table below (prescription or nonprescription) is prohibited until completion of all study activities
  • A subject who has manifestations of advanced complications from poorly controlled or longstanding diabetes such as diabetic retinopathy, diabetic neuropathy and cardiovascular complications including, but not limited to coronary artery disease, peripheral vascular disease, or cerebrovascular disease such as transient ischemic attack [TIA], cerebral infarct, or cerebral hemorrhage
  • History or current diagnosis of cardiac dysrhythmias or heart disease, defined as symptomatic heart failure (New York Heart Association class III or IV), myocardial infarction, unstable angina requiring medication
  • History of recurrent severe hypoglycemia (more than 1 event ≤ 6 month)
  • Subjects with clinically active malignancy
  • Personal or family history of hypercoagulability or thromboembolic disease, including deep vein thrombosis and/or pulmonary embolism (PE)
  • History of surgical treatment for obesity (bariatric surgery, gastric banding, etc.) or any other gastrointestinal surgery (including appendectomy, cholecystectomy), any malabsorption disorder, severe gastroparesis, any GI procedure for weight loss (including LAP-BAND®), as well as clinically significant gastrointestinal disorders (e.g. peptic ulcers, severe GERD) at Screening
  • Known history or positive test for hepatitis B surface antigen (HBsAg), hepatitis C antibody (HCV Ab), human immunodeficiency virus type 1 (HIV-1) or type 2 (HIV-2)
  • History of any recent traumatic injury, including intracerebral hemorrhage and visceral injury
  • Identification of risk of hypoglycemia or severely uncontrolled diabetes in screening visit metabolic assessments (CGM, OGTT, and fasting blood draws)
  • History of renal disease or abnormal kidney function tests at Screening (glomerular filtration rate [GFR] < 60 mL/min/1.73m2 as estimated using the MDRD equation)
  • History or active hepatic disease or clinically significant abnormal hepatic function tests at Screening suggestive of hepatic impairment (e.g., ALT and/or AST >2 x ULN, GGT >2 x ULN, total bilirubin > 1 x ULN)
  • Current use of any drugs (other than current treatment for diabetes mellitus) that are known to interfere with glucose or insulin metabolism as stated below in table prohibited medication
  • Subject is unable to tolerate adhesive tape or has any unresolved adverse skin reaction in the area of the glucose sensor placement
  • Implanted pacemaker or cardioverter/defibrillator (AICD)
  • Mental incapacity, unwillingness or language barriers precluding adequate understanding and to follow verbal commands during the ultrasound session or cooperation
