Plain English Summary

Background and study aims
Fresh impact injuries are common injuries associated with sports activities and normal daily activities. These injuries are often recognized by the onset of immediate localized pain, swelling, discolouration and limited joint range of motion near the injury. They are characterized by direct trauma to the muscle group with subsequent pain and swelling resulting from bleeding within the muscle. The aim of this study is to assess whether a diclofenac medicated plaster reduces pain caused by fresh impact injuries of the limbs.

Who can participate?
Patients aged between 18 and 60 years with fresh impact injuries of the limbs (sprain, strain, contusion) not older than 3 hours.

What does the study involve?
Patients will be randomly allocated to be treated with either the diclofenac patch group or a placebo (dummy) patch. The treatment will be administered two times a day, in the morning and in the evening for 7 days.

What are the possible benefits and risks of participating?
If you receive the diclofenac plaster, it is possible that your pain may be reduced. If your pain gets worse you will be withdrawn from the study. Caution is required in patients with gastric and intestinal ulcers. For safety reasons these patients may not participate in the trial. Some skin reactions could be expected such as rash, itching, burning and reddening of the skin.

Where is the study run from?
The study takes place in four centres in Germany. Some of them are close to sport centres with several sport grounds. The coordinator site is headed by Prof. Hans Georg Predel.

When is the study starting and how long is it expected to run for?
The study started in September 2010 and ran until April 2011.

Who is funding the study?
Fidia Farmaceutici S.p.A. (Italy).

Condition

Impact injury of the limbs

Intervention

Treatment (diclofenac or placebo) is started after enrolment into the trial (at Visit 1, after obtaining informed consent and after physical examination and performance of all trial-specific measurements) and administered two times a day, in the morning and in the evening, and continued until Day 8, inclusive.

The visits were performed according to the following scheme:
Visit 1 - day 1 (baseline): enrollment and start of therapy
Visit 2 - day 2 (24 ±4 hours after baseline): during study treatment
Visit 3 - day 3 (48 ±4 hours after baseline): during study treatment
Visit 4 - day 5 (4 days after baseline): during study treatment
Visit 5 - day 8 (7 days after baseline): patient's final evaluation

Drug names

Primary outcome measures

Absolute change in pain on movement - assessed while moving the arm lifting a barbell (in case of injury of upper limb) or walking five steps on an even surface (in case of injury of lower limb)

Measured at baseline Visit 1 (Day 1) to Visit 3 (Day 3) assessed by patient on Visual Analogue Scale (VAS)

Secondary outcome measures

1. Pain at rest, assessed by patient on VAS on Visit 3, 4 and 5
2. Pain on active movement, assessed by patient on VAS on Visit 4 and 5
3. Algometric pain measurement directly on the skin at the injured site and the contralateral site on Visit 3 and Visit 4
4. Time to onset of efficacy assessed by patient on Visit 2, possibly on Visit 3, 4 and 5, too. If the patient feels that the medication is not yet working at Visit 2, the investigator will ask the patient after the onset of efficacy again at subsequent visits until Visit 5
5. Global assessment of treatment efficacy by patient and by investigator, according to a 5-point Likert scale (none, poor, fair, good, excellent) at Visit 2, 3, 4, 5
6. Consumption of rescue medication at each visit

Safety outcomes:
1. Global assessment of local tolerability by patient and by investigator according to a 4-point scale (poor, fair, good, excellent) at Visit 2, 3, 4, 5
2. Changes from baseline to Visit 5 in general physical examination
3. Changes from baseline to Visit 3 and 5 in vital signs
4. Recording of adverse events
