83% of subjects maintained a clinically meaningful benefit with a 3 or more point improvement in Revised Venous Clinical Severity Score (rVCSS)

9.1 point average rVCSS improvement among the clinically meaningful benefit cohort

Subjects experienced a median 74% improvement in leg pain

Interim follow-up data indicate sustained improvements across all venous-specific quality-of-life (QoL) indicators

83.3% of subjects (n=35/42) maintained a clinically meaningful benefit, defined as an improvement of 3 or more points in the revised Venous Clinical Severity Score (rVCSS).

9.1 point average rVCSS improvement among the responder cohort.

A median 74% improvement in leg pain, as measured by the Visual Analog Scale (VAS).

Wound healing outcomes in 17 subjects with 25 ulcers showed that 60% of ulcers healed completely, 24% decreased in size, and 16% increased in size.

Patient-reported outcomes also demonstrated sustained improvements across all venous specific QoL indicators (VEINES-QoL/Sym).
