Outcome Measures

Primary Outcomes (1)

  • BEAT-Calci Wound Assessment Scale (BCWAS) - Baseline to Week 12

    To determine whether addition of the intervention changes the sentinel ulcer from Baseline to Week 12 on the BEAT-Calci Wound Assessment Scale. This is an 8-point ordinal categorical scale of change since baseline, which will be used to determine each participant's outcome. The scale is described as: 1. Complete epithelialisation of the sentinel ulcer 2. \>50% reduction in sentinel ulcer surface area 3. 20-50% reduction in sentinel ulcer surface area 4. 0-20% reduction in sentinel ulcer surface area 5. Any increase in sentinel ulcer surface area 6. Development of new ulcers 7. Amputation due to an ulcer 8. All-cause death

    Week 12

Masking Details
Blinding of all parties will not be possible for all domains. The default position of the BEAT-Calci platform is that treatments determined by randomization will be blinded to as high a level is feasible. Within practical domains, a blind will be adopted, whereby participants, site personnel, trial investigators and outcome assessors will remain blinded to the treatment from the time of randomization until database lock of the comparisons to which that participant is contributing data. In blinded domains, randomization data will not be accessible by anyone else involved in the trial with the following exceptions: (1) data managers who work on the randomization and drug management system, (2) unblinded statistician(s) involved with the response adaptive randomization, and (3) the unblinded biostatistician who prepares reports for the IDMC. Information on the blind, or lack thereof, per domain will be described in the respective Domain-Specific Appendix.

IPD Sharing
Will share

Trial data will be disseminated in the form of a publication to a relevant clinical journal and presentation at appropriate scientific conferences. Individual participant data that underlie the results reported, after de-identification (text, tables, figures, and appendices), may be shared with Investigators whose proposed use of the data has been approved by a review committee identified for this purpose.

Access Criteria
* No data should be released that would compromise the trial, unless specifically for safety reasons. * There must be a strong scientific or other legitimate rationale for the data to be used for the requested purpose. * Investigators should have a period of exclusivity in which to pursue their aims with the data, before key trial data are made available to other researchers. * Adequate resources must be available in order to comply with the request, and the scientific aims of the study must justify the use of such resources. * Data release complies with the relevant regulations from all relevant countries.
