Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Reconstituted High-density lipoproteins (rHDL) will be applied topically three days a week for 6 weeks.
The treatments will be applied by a wound care nurse or podiatrist on the study who will make home visits and also attend clinic visits. This will ensure adherence to the intervention.
The rHDL will be applied in the first 24-72h post-minor amputation after inspection to make sure that the new wound bed is free of infection.
Intervention code [1] 313707 0
Treatment: Drugs

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Yes - The person who recruits the patient will not be aware of what treatment the patient will receive. Allocation will involve contacting the holder of the allocation schedule who will be located off-site that there is an eligible patient for the trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using procedures like coin-tossing and dice-rolling
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes

Efficacy
Statistical methods / analysis
Study power: Based on a wound healing trial in the Lancet, we predict complete wound closure (area 0cm2) in 50% of the rHDL treatment group, with less wound closure in the placebo group (remaining wound area ~3cm2) at 16 weeks. A total of 128 subjects (64/group) will give 80% power to detect a difference of 3cm2 with SD=6cm2 at 5% significance level using a two-sided t-test. Accounting for non-compliance/losses-to-follow-up of 10%, we aim to recruit 142 subjects (71/group). In the experience of Principal Investigator Prof Robert Fitridge, >90% continue clinic attendance after amputation.

Statistics: Comparisons between groups will use two-tailed t-tests or one-way ANOVA with post hoc analyses for pairwise comparisons (Newman-Keuls multiple comparison) using SAS software. Adjusted analyses over time will use Generalised Linear Modelling. Statistical inferences will be drawn at 2P<0.05.
