1) Triple sharpening

The top of the cannula (patient tip) undergoes 3grinding treatments:• one central sharpening (A)• two side sharpening (B)

All main Insupen pen needles are sharpenedaccording to the new Extr3me technology,ensuring a more comfortable penetration.

1) Extr3me: longer bevels

The new geometry makes the tip even sharper: bevels are longer andless inclined while the length of the cannula doesn’t change. Thisleads to a reduced penetration force.

Fear and pain of injections:

• 94% of insulin users show symptoms of anxiety, distress or

phobia around blood and injury from injections (1)

• 33% of insulin users are afraid of their injections (2)

• 75% of newly diagnosed children < 9 years old have a fear of

injections (3)

• 47% of people with diabetes say they would be more likely to

follow their prescribed insulin regimen if a product easing pain

and discomfort of injections was available (4)

2) External diameter: patient’s attitude

• In a 2004 study, blinded assessments of pain showed no significantdifference in pain scores for the 2 needle lengths tested (6mm and12.7mm). This observation would indicate that, at least under theconditions of needle testing in this clinical trial, the discomfort ofpuncturing dermal tissues did not differ materially for the 2 lengths.

• The questions specifically comparing patient perception toward the 2needles showed however a marked preference for the shorter, finerneedle: when specifically asked about needle preference, patientsindicated that they considered the shorter needle (6mm) easier touse.

4) Length: pain and ease of use

4) Length: dermis thickness

* Skin and subcutaneous adipose layer thickness in adults with diabetes at sites used for insulin injection: implication for needlelength recommendation, Michael A. Gibney, Christina H. Arce, Karen J. Byron, Laurence J. Hirsch”.

The thickness of the dermis is unrelated to BMI and fluctuates, onaverage, between 1.8 and 2.5 mm according to the injection site*.

37

4) Length: suitable needle

* New injection recommendations for patients with diabetes, A Frid, L. Hirsch, R. Gaspar, D. Hicks, G. Kreugel, J. Liersch, C.Letondeur, J.P. Sauvanet, N. Tubiana-Rufi, K. Strauss - Diabetes & Metabolism 36 (2010) S3-S18

The new guidelines for insulin injections recommend to use shortneedles (4 to 6mm) for all patients, including those with a sturdyphysical build, because they can pass through the dermis layer andreach the subcutaneous tissue.

38

We have decided however to have a wide32G range in order to let freedom ofchoice:

• to the patient, who can choose acomfortable pen needle (32G) in avariety of lengths matching his/her ownfavorite injection technique (90°, 45°,with pinch etc)

• to the professional, who –according tohis/her own experience- may prescribea specific pen needle for each patient

4) Length: Insupen’s choice

The above injection techniques are recommended in the Clinical Study “New injection recommended for patients with diabetes”, AndersFrid, Ruth Gaspar, Debbie Hicks, Larry Hirsch, Gillian Kreugel, Jutta Liersch, Corinne Letondeur, Jean-Pierre Sauvanet, Nadia Tubiana-Rufi, Kenneth Strauss - Vol.36 – 2010, Diabetes & Metabolism.”

Special Medical grade silicone is laid evenly all over the entire needlesurface.

3) Silicone

In combination with a precisesharpening and polishing of theneedle, this ensures its smoothsliding into the skin.

46

4) CompatibilityThe updated ISO 11608 norm (ISO 11608-2:2012) prescribes that thecompatibility between pen needles and pen injector has to be assessedthrough testing the needles with every single pen.The list of the compatible pens is listed on the packs and it’s periodicallyupdated.The previous revision (EN ISO 11608-2:2000) instead stated that each “Type A”pen needle was compatible with each “Type A” pen injector.

These data suggest that if participants reuse pen needles, they have just as muchchance of having lipohypertrophy as not, but if they do not reuse pen needles theyhave a modest (and significant) reduction in the risk of lipohypertrophy, eventhough many of those who do not reuse pen needles still develop lipohypertrophy.

• These new recommendations come from a 2-steps process:o the results of the second Injection Technique Questionnaire (ITQ)

survey (2008-2009), involving more than 4.300 insulin-injectingpatients with diabetes from 171 centers in 16 countries, making it one ofthe largest multi-center studies of its kind in diabetes. The outcomeswere then presented for review and revision to 127 experts from 27countries at the TITAN workshop in September 2009.

o a systematic literature analysis conducted for all peer-reviewedstudies and publications on injections in diabetes: an international groupof experts met regularly over a two-year period to review this literatureand draft the recommendations. Of 292 articles reviewed, 157 werefound to meet the criteria of relevance to the recommendations.

Injection techniques: the latest guidelines

69

• Many studies show that to safeguard normal tissue one mustproperly and consistently rotate sites

• Patients should be taught an easy-to-follow rotation pattern fromthe onset of injection therapy

• The below scheme with proven effectiveness involves dividing theinjection site into quadrants (or halves when using the thighs orbuttocks), using one quadrant per week and moving alwaysclockwise, as shown by figures below

• Injections within any quadrant or half should be spaced at least1cm from each other in order to avoid repeat tissue trauma

Where to inject: site rotation

New injection recommendations for patients with diabetes, A Frid, L. Hirsch, R. Gaspar, D. Hicks, G. Kreugel, J.Liersch, C. Letondeur, J.P. Sauvanet, N. Tubiana-Rufi, K. Strauss - Diabetes & Metabolism 36 (2010) S3-S18

Abdominal rotationpattern by quadrants

Thigh and Buttocks rotational pattern by halves

70

The choice of the injection site is anessential element for the glycaemiacontrol, since there is (especially withfast insulin) a relevant variability of theabsorption speed (= passage intoblood) for non-analogue insulins.

From fastest to slowest:

abdomen, shoulder, buttock, thigh

Absorption speed depends also on thetype of insulin (human, analogues,rapid- or slow-acting). For example,soluble human insulins may have aslower absorption profile than rapid-acting analogs. The most rapidabsorption of soluble human insulins isin the abdomen, which should be thepreferred site.

Where to inject: absorption speed

Recommended injection sites

New injection recommendations for patients with diabetes, A Frid, L. Hirsch, R. Gaspar, D. Hicks, G. Kreugel, J.Liersch, C. Letondeur, J.P. Sauvanet, N. Tubiana-Rufi, K. Strauss - Diabetes & Metabolism 36 (2010) S3-S18

71

Clinical evidences and literature varies onto this subject.

Several healthcare professionals suggest to make the skinfold inorder to reduce the risk of IM injections, which can lead to a too fastinsulin absorption and therefore hypoglycaemia.

Here below general recommendations for adults.

How to inject: the appropriate technique

New injection recommendations for patients with diabetes, A Frid, L. Hirsch, R. Gaspar, D. Hicks, G. Kreugel, J.Liersch, C. Letondeur, J.P. Sauvanet, N. Tubiana-Rufi, K. Strauss - Diabetes & Metabolism 36 (2010) S3-S18

72

• Lifting a skin fold and/or injecting at a 45-degree angle are especiallyimportant in slim or normal weight patients and in those injecting into thelimbs or into slim abdomens, particularly when using needles ≥8 mm.

• Skin folds are essential when the distance from skin surface to the muscleis less than the length of the needle.

• Lifting a skin fold is an easy and effective means for ensuring SCinjections.

• A proper skin fold is made with the thumb and index finger (possibly withthe addition of the middle finger). Lifting the skin by using the whole handrisks lifting muscle with the SC tissue and can lead to IM injections.

How to inject: the skin fold

• The skin fold should not besqueezed so tightly that it causesskin blanching or pain.

New injection recommendations for patients with diabetes, A Frid, L. Hirsch, R. Gaspar, D. Hicks, G. Kreugel, J.Liersch, C. Letondeur, J.P. Sauvanet, N. Tubiana-Rufi, K. Strauss - Diabetes & Metabolism 36 (2010) S3-S18

73

• Lipohypertrophy is a thickened, ‘rubbery’ lesion that appears in the SCtissue of injecting sites in up to 50% of patients who inject insulin.

• Patients should not inject into areas of lipohypertrophy since insulinabsorption can be delayed or made erratic.

• Detection of lipohypertrophy requires both visualization and palpation ofinjecting sites, as some lesions can be more easily felt than seen.

• Figure 1 illustrates visible lipohypertrophy in a woman who had injected inthe same two locations below the umbilicus for twelve years.

Lipohypertrophy

Figure 2

• Figure 2 illustrates the detection ofpalpable lipohypertrophy bycomparing a fold of normal skin(left) with lipohypertrophic tissue(right). Normal skin can bepinched tightly together, whilelipohypertrophic lesions cannot.

New injection recommendations for patients with diabetes, A Frid, L. Hirsch, R. Gaspar, D. Hicks, G. Kreugel, J.Liersch, C. Letondeur, J.P. Sauvanet, N. Tubiana-Rufi, K. Strauss - Diabetes & Metabolism 36 (2010) S3-S18

74

• Inject slowly and ensure that the plunger (syringe) or thumbbutton (pen) has been fully depressed.

• When using a pen, wait another 10 seconds after dose deliverybefore removing the needle in order to avoid leakage/reflux; thisensures full delivery of the injected dose.

• Massaging the site before or after injection may speed upabsorption and is generally not recommended.

• Tips for making injections less painful include:o Keeping insulin in use at room temperature, since cold

insulin can be more painful when injected;o If using alcohol, injecting only when the alcohol has dried

out;o Not injecting at hair roots;o Using a new needle at each injection.

75

Fear and pain of injections:

• 94% of insulin users show symptoms of anxiety, distress or

phobia around blood and injury from injections (1).

• 75% of newly diagnosed children < 9 years old have a fear of

injections (3).

• 47% of people with diabetes say they would be more likely to

follow their prescribed insulin regimen if a product easing pain

and discomfort of injections was available (4).
