KIT THAT'S COMING SOON

MICRONEEDLE CGM

This concept is being worked on at Imperial College London.

I talked to Dr Monika Reddy about the project and how it's

different from other CGM solutions. By Sue Marshall

A

t At Imperial College

London as part of

diabetes research

projects there are several

technology solutions

being undertaken by Professor Nick

Oliver and his team. As part of this team

Dr Monika Reddy has been working

on one project in particular looking into

microneedle CGM.

Reddy explains, "We work closely with

a small team of chemical and biomedical

engineers to further ideas that can

potentially improve control and quality of life

for people with diabetes. Currently people

with Type 1 diabetes and Type 2 diabetes

treated with insulin are encouraged to

do finger-prick blood testing four times

a day. More recently we've been able to

recommend CGM to individuals at high

risk in line with NICE guidelines. However,

virtually all current CGM involves sensors

placed directly into the skin, with a needlelike filament

that is placed subcutaneously

into tissue. There are some downsides to

this method, including some discomfort,

the fact that it can lead to a reduction in

sensor accuracy over time and when

blood glucose is low (hypoglycaemia).

Subcutaneous CGM does not use capillary

blood but interstitial fluid, and that means

it can be slightly behind the accuracy of

capillary blood test results, as much as 15

minutes behind."

So, can there be an improvement

in the technology to get all the benefits

of subcutaneous sensor CGM but

with greater accuracy, and what about

ease-of-wear too? Says Reddy, our

microneedle CGM concept still uses

the same chemical - glucose oxidase

- as used in other CGM systems, but

instead of using one filament it consists

of a small wearable patch containing a

series of very small spikes or needles that

penetrate only the outermost skin layer.

By using several spikes you get more

than one glucose measurement, which

can improve accuracy. Current CGM

solutions cost around £150 a month,

and this is a cost that limits the ability of

HCPs to recommend it to all people with

Type 1 diabetes. We are working on a

microneedle CGM that should be more

affordable as well as more accurate."

Getting the needle

I don't know about anyone else, but while

CGM can bring its own problems - you

can knock them off, they can cause

bleeding and some discomfort at insertion

and get a bit itchy, but in the main they

are not painful. I'm not sure I'm liking the

sound of 'a series of small spikes'. But

hold on, how this would feel to wear

has been a key point in designing the

solution. "We not only want to push this

technology forward in order to improve on
