Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Autologus Platelet Gel applied to target ulcer in addition to standard best practice compression therapy.
Magellan APG kits will be used for the preparation of the APG treatment. A portion of the patient's blood will be placed in the kit that is linked to a centrifuge which will add fibrin and be set to spin the blood to develop the gel. The Wound Clinic Nurse will draw 60 mls of blood from participants to develop the APG (50 mls) and to send to lab for analysis (10 mls). The APG will be prepared as per standard operating procedure. The APG will take 20 – 30 minutes to prepare. During this time the participant will remain on a bed in the wound clinic. The gel preparation can either be placed or sprayed on to the VLU depending on depth of wound. The gel will be applied once. All participants will be treated with standard best practice wound dressing and compression therapy. Compression type will be delegated by the clinician after discussion with the patient. Participants will be informed that the compression bandage must not be removed during the treatment period.
Compression bandage must not be removed during week one following gel application,
One week after gel application, compression will be removed by study nurse; the ulcer assessed and compression replaced once weekly until ulcer healed or until 12 weeks.

Outcomes
Primary outcome [1] 299599 0
Complete healing of target ulcer. Healing is defined as 100% epithelialisation with no exudate which will be assesed by direct observation by the study nurse. A digital photo will be taken for DCF documentation.
Timepoint [1] 299599 0
12 weeks from application of APG. The ulcer will be assessed at Baseline and every 4 weeks after APG application until healed or 12 weeks whichever comes first. The ulcer outline will be traced on acetate grids and ulcer area calculated. The visit at which complete healing is obsereved will be recorded.
Secondary outcome [1] 327656 0
The rate of ulcer recurrence over 3 months after healing
Timepoint [1] 327656 0
Healed participants before 12 weeks or at 12 weeks will be assessed at 3 months after healing for recurrence by the Study Nurse or by medical record review.

Eligibility
Key inclusion criteria
Eligible participants will be aged over 18 years and have a chronic VLU (target ulcer) that has been present for more than 4 weeks with no improvement. Participants must have an ABPI greater than or equal to 0.7 mmHg to exclude significant arterial insufficiency. The eligible target ulcer will have an area greater than or equal to 1 cm2 to less than or equal to 40 cm2 as measured by acetate tracing grid techniques (largest ulcer on limb and separated from other ulcers by at least 1 cm). If more than one leg ulcer is present, the largest ulcer will be treated.
