Clinical Trial Summary

This global platform study will evaluate multiple interventions, across several domains of therapeutic care, in adult patients with kidney failure and newly diagnosed calciphylaxis.

Description:

BEAT-Calci is a randomized, adaptive, multi-center, platform trial that will evaluate multiple interventions, across several domains of therapeutic care. The objective of the study is to establish high-quality evidence on the effect of a range of interventions in patients with kidney failure and newly diagnosed calciphylaxis. Calciphylaxis is a rare disease affecting 1-2 people in 10,000.

The trial will commence with a Dialysis Membrane Domain and Pharmacotherapy Domain. The Pharmacotherapy Domain of BEAT-Calci is a placebo-controlled, double blind, response adaptive, randomised controlled trial that will investigate whether any of the pharmacotherapeutic agents is superior to placebo in improving outcomes. The Dialysis Membrane Domain of BEAT-Calci is an open-label, randomised controlled two-way comparison between two different dialysis technologies.

The BEAT-Calci Wound Assessment Scale (BCWAS) is the primary endpoint for the trial. It is an 8-point ordinal categorical scale of disease outcomes and will be used to determine each participant's outcome.

The trial will utilise a Bayesian adaptive sample size re-estimation approach for sample size calculations. The trial will continue to recruit until predefined superiority or futility rules are met. As the trial progresses, in response to information accumulating during the trial, there are various adaptations that can occur, including addition or removal of an intervention arm, response adaptive randomisation and addition of new therapeutic domains.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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: Complete epithelialisation of the sentinel ulcer; >50% reduction in sentinel ulcer surface area; 20-50% reduction in sentinel ulcer surface area; 0-20% reduction in sentinel ulcer surface area; Any increase in sentinel ulcer surface area; Development of new ulcers; Amputation due to an ulcer; All-cause death	Week 12
Secondary	BEAT-Calci Wound Assessment Scale - Baseline to Week 26	To determine whether addition of the intervention changes the sentinel ulcer from Baseline to Week 26 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: Complete epithelialisation of the sentinel ulcer; >50% reduction in sentinel ulcer surface area; 20-50% reduction in sentinel ulcer surface area; 0-20% reduction in sentinel ulcer surface area; Any increase in sentinel ulcer surface area; Development of new ulcers; Amputation due to an ulcer; All-cause death	Week 26
Secondary	Distribution of each of the individual components of the BCWAS, assessed at Weeks 4	To determine whether addition of the intervention changes the distribution of each of the individual components of the BEAT-Calci Wound Assessment Scale, assessed at Weeks 4; Scale described as: Complete epithelialisation of the sentinel ulcer; >50% reduction in sentinel ulcer surface area; 20-50% reduction in sentinel ulcer surface area; 0-20% reduction in sentinel ulcer surface area; Any increase in sentinel ulcer surface area; Development of new ulcers; Amputation due to an ulcer; All-cause death	Week 4
