The Flower Study

This is a study to trial a new flower extract in men with pre-diabetes to see if it lowers blood glucose levels. It requires 4 visits to Wellington Regional Hospital for 3 hours each time. You may be eligible if you are:

  • male
  • aged between 18 and 65
  • have pre-diabetes (HbA1c 41-49).


This is a study for men and women with pre-diabetes, being run in collaboration with the University of Otago. It aims to see whether probiotics and cereals can prevent diabetes. For more information and a sign-up form, visit the study website at

Scored Study

The purpose of this study is to trial a medical device that delivers a one-off low-level radiofrequency energy through the wall of the blood vessel to the liver to disrupt the nerves that lead to the liver. Previous research has shown that disrupting these nerves may lead to a lowering of blood sugar levels in people with type 2 diabetes. This procedure may be useful for people who have trouble controlling their blood glucose levels.

You may be eligible if you:

  • are aged over 18 years
  • have type 2 diabetes
  • need help with blood sugar control.

Fidelio and Figaro

We are looking for people to take part in a clinical trial for people with Type 2 Diabetes who have raised protein in the urine. This is a trial of a tablet to reduce the damage done to kidneys and heart by diabetes. There are two arms to this study, one looking at protecting the kidneys (Fidelio) and one looking at protecting the heart (Figaro).

Low Carbohydrate Diets in Type 1 DM

This study is the third in our research programme in this area and takes the insulin to protein ratio developed in the last study and is trialling it in real life. We are looking for people with type 1 diabetes who are following a low carbohydrate eating plan (or are happy to follow one!) and are happy to trial the extra insulin ratio for three months. The trial requires 4-5 visits to the clinic and using a freestyle libre, which we will provide for periods of the study.
