Investigation of Pain During Subcutaneous Injections With Different Injection Speed and Volume Combinations

January 18, 2017 updated by: Novo Nordisk A/S
This trial is conducted in Europe. The aim of this trial is to assess and describe the pain in relation to subcutaneous (under the skin) injection of different combinations of injection speed and volume with respect to acceptance of the injection pain and backflow.

Description

Inclusion Criteria:

  • Informed consent obtained before any trial-related activities.
  • Type 1 or type 2 diabetes
  • Daily injection(s) with anti-diabetic drug (insulin or Glucagon like Peptide-1 (GLP-1) analogues) via pen-injector or vial/syringe for more than 6 months

  • Injection of more than 40 units of insulin per injection
  • Continuous Subcutaneous Insulin Infusion use within the last 6 months
  • Continuous Glucose Monitoring use within the last 6 months
  • Intake of any pain-relieving or analgesic within the last week (excluding low dose aspirin in cardio vascular prophylactic doses)
  • Known active or in-active skin disease in the injection area or that may affect pain perception
  • Anti-coagulant treatment within the last month (low dose of aspirin in cardiovascular prophylactic doses is allowed. However, not on the day of the injections)

Design Details

  • Primary Purpose: Supportive Care
  • Allocation: Randomized
  • Interventional Model: Crossover Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Different injection speed and volume combinations
The study consists of 80 treatment arms in a cross-over design with 19 treatments and 19 periods. The 80 treatment arms will represent different orders of the 19 treatments and each treatment arm will be used for one subject. A subject not completing all treatments will be replaced by another subject using the same treatment arm.
Subjects will receive 19 injections in randomised order of which 13 will be in the abdomen and 6 in the thighs. Out of the 19 injections, 2 are needle insertions only. The remaining 17 injections represent different combinations of injection speed and volume of sodium chloride 0.9% solution for injection. The order of the injection speed and volume combinations will be blinded for the subject and the pain will be evaluated by the subject on a VAS (Visual Analogue Scale).
Solution for injection.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Injection Pain (VAS mm)
Time Frame: 1 minute (±30 sec) after each injection
Calculated as the least square mean estimate of the difference in injection pain on a VAS (mm) between different factor levels corresponding to injection region, injection volume and injection speed (pain was assessed using an electronic VAS consisting of a 100 mm line where 0 mm corresponded to no pain and 100 mm corresponded to worst pain. After each injection, the subjects rated their pain perception at the electronic VAS by marking the 100 mm line).
1 minute (±30 sec) after each injection

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Acceptance of Injection Pain After Injection of Different Volumes.
Time Frame: 1 minute (±30 seconds) after each injection
Acceptance of pain was rated subjectively as yes or no by the subject after each injection.
1 minute (±30 seconds) after each injection
Acceptance of Injection Pain After Injection at Different Speeds.
Time Frame: 1 minute (±30 sec) after each injection
Acceptance of pain was rated subjectively as yes or no by the subject after each injection.
1 minute (±30 sec) after each injection
Acceptance of Injection Pain After Injection in the Thighs Versus Abdomen.
Time Frame: 1 minute (±30 seconds) after each injection
Acceptance of pain was rated subjectively as yes or no by the subject after each injection.
1 minute (±30 seconds) after each injection
Estimated Mean Differences in the Volume of Backflow (uL) in the Abdomen After Different Injection Volumes and Speeds as Compared to Needle Insertion
Time Frame: 2 minutes (±30sec) after each injection
Backflow was measured after each injection by placing a filter paper over the injection site after the injection was given and until the liquid was absorbed. The size of the wet spot on the filter paper served as a measure of the backflow. The treatment effect on backflow was calculated as the least square mean estimate of the difference in backflow after injection in the abdomen at different volume and speed combinations.
2 minutes (±30sec) after each injection
Estimated Mean Differences in the Volume of Backflow (uL) in the Thighs After Different Injection Volumes and Speeds as Compared to Needle Insertion
Time Frame: 2 minutes (±30sec) after each injection
Backflow was measured after each injection by placing a filter paper over the injection site after the injection was given and until the liquid was absorbed. The size of the wet spot on the filter paper served as a measure of the backflow.
