AI-kivonat: who the study is looking for

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 35 to 70 with type 2 diabetes that is not well controlled on several glucose-lowering medicines, including a GLP-1RA. It tests the safety of RJVA-001 given by endoscopic ultrasound into the pancreas.

Age
35 to 70 years (inclusive)
Sex
All sexes can join.
Disease stage
Type 2 diabetes, not well controlled on several glucose-lowering medicines. Adding or changing treatment is judged unacceptable by the investigator. Insulin therapy has been deferred.
Earlier treatment
Must already take a GLP-1RA at the maximum tolerated maintenance dose, with ongoing benefit, plus permitted non-insulin glucose-lowering medicines. No new weight loss medicines during the study.
Biomarker or test result
Normal calcitonin level and normal thyroid function. Fasting plasma glucose, hemoglobin A1c, body mass index and random C-peptide levels must be as stated in the study protocol.

Main reasons for not taking part

  • Type 1 diabetes, a history of ketoacidosis, monogenic diabetes, latent autoimmune diabetes of adults, or islet cell autoantibodies
  • History of chronic or acute pancreatitis
  • History of dose-limiting side effects from GLP-1RA medicines
  • History of active malignancy, or medullary thyroid carcinoma in the person or family
  • Contraindication to upper gastrointestinal endoscopy, to sedation or anesthesia, or to steroids or sirolimus
