Conditions

CLTI defined as Rutherford category 4 or 5

Brief summary

Amputation-free survival at 12 months, defined as time from randomization until major amputation (defined as above-the-ankle amputation) or death from any cause, whichever occurs first, for all subjects.

Detailed description

Individual component of the combined primary endpoint: major amputation, overall mortality at 12 months., MALE, a combined secondary endpoint at 12 months, defined by the occurrence of either one of the following items whichever occurs first: re-intervention on the index arterial segment (Target Lesion Revascularization/TLR), acute limb ischemia, major amputation of the index limb (above-the-ankle amputation), MACE, a combined secondary endpoint at 12 months, defined by the occurrence of either of the following items whichever occurs first: myocardial infarction, stroke or cardiovascular death, Change between inclusion and 12 months in quality of life using a disease-specific QoL Questionnaire commonly used in CLTI patients (VascuQoL-6 questionnaire) and a generic one, the EQ-5D-5L questionnaire, Fatal bleeding and/or symptomatic bleeding in a critical area/organ (such as intracranial, intraspinal, intraocular, retroperitoneal, intra-articular or pericardial, or intramuscular with compartment syndrome), Bleeding causing a fall in hemoglobin level of 2 g/dL or more, Bleeding leading to transfusion of two or more units of whole blood or red cells, Requiring intervention (medical practitioner-guided medical or surgical treatment to stop or treat bleeding, including temporarily or permanently discontinuing or changing the dose of a medication or study drug),, Resulting in hospitalization or inducing an increase in the duration of hospitalization,, Prompting evaluation (leading to an unscheduled visit to a healthcare professional and diagnostic testing, either laboratory or imaging), Net clinical benefit outcome (composite outcome comprising deaths, MALE, MACE and major bleeding events), Quality of life: VascuQol-6 and EQ-5D-5L scales, Costs at 12 months, Incremental cost-effectiveness and utility ratio (ICUR)
