|
Clinically relevant minor (non-major) bleeding was defined as any bleeding compromising hemodynamics, leading to hospitalization, subcutaneous haematoma more than 25 cm^2, intramuscular haematoma, epistaxis lasting for more than 5 minutes, spontaneous gingival bleeding, macroscopic hematuria and gastrointestinal hemorrhage (including at least 1 episode of melaena or hematemesis), rectal blood loss, hemoptysis, and any other bleeding with clinical consequences.

Number of Participants With Intact Skin Healing
Tijdsspanne: Baseline through Week 24 (EOT) or ET
|
Intact skin healing was defined as 100 percent reduction in ulcer surface area with full epithelialisation.
The ulcer area was measured in square millimetre (mm) by measuring the longest width and length of the ulcer after debridement.
The area was calculated from an acetate tracing.
Ulcers were also documented by standardized photographs.
The largest ulcer was considered the study ulcer in participants with multiple ulcers.
|
Baseline through Week 24 (EOT) or ET
|
|
Number of Participants With Improved Ulcer Healing
Tijdsspanne: Baseline through Week 24 (EOT) or ET
|
Improved ulcer healing was defined as greater than or equal to 50 percent reduction in ulcer surface area from baseline of the A6301083 study excluding intact skin healing.
The ulcer area was measured in square mm by measuring the longest width and length of the ulcer after debridement.
Ulcers were also documented by standardized photographs.
|
Baseline through Week 24 (EOT) or ET
|
|
Number of Participants Who Underwent Amputation
Tijdsspanne: Baseline through Week 24 (EOT) or ET
|
A major amputation was defined as above the ankle and was reported as below-the-knee and above-the-knee amputations.
A minor amputation was defined as below the ankle amputation.
|
Baseline through Week 24 (EOT) or ET
|
|
Time to Intact Skin Healing
Tijdsspanne: Baseline through Week 24 (EOT) or ET
|
Median time (in months) taken to achieve intact skin healing which was defined as 100 percent reduction in ulcer surface area with full epithelialisation.
|
Baseline through Week 24 (EOT) or ET
|
|
Time to First Amputation
Tijdsspanne: Baseline through Week 24 (EOT) or ET
|
Baseline through Week 24 (EOT) or ET
|
|
|
Number of Participants With Major Cardiovascular Disease Events (MCVE)
Tijdsspanne: Baseline through Week 24 (EOT) or ET
|
MCVE were defined as death due to vascular cause; non-fatal myocardial infarction (MI) excluding procedure related to MI; coronary revascularization procedures not related to MIs; hospitalization for unstable angina or non-fatal stroke.

Baseline through Week 24 (EOT) or ET
|
|
11-point Likert Pain Scale
Tijdsspanne: Baseline and Week 24 (EOT) or ET
|
The 11 point Likert pain scale which used a 0 (no pain) to 10 (worst possible pain) point rating system was used to assess participant's pain score.
No distinction was made between neuropathy and inflammatory (nociceptive) pain.
|
Baseline and Week 24 (EOT) or ET
|
|
36-Item Short-Form Health Survey (SF-36) Score
Tijdsspanne: Baseline and Week 24 (EOT) or ET
|
SF-36 is a standardized survey evaluating 8 aspects of functional health and well being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health.
The score for a section is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning).
