NEW CASE STUDIES: SEE HOW AFFINITY® HELPED TO SUPPORT HEALING

RCT and real-
world evidence

As a protective wound covering, Affinity® was proven to support healing in a prospective, multicenter, randomized controlled trial (RCT)1

  • Assessed efficacy of Affinity vs standard of care (SOC)* in 76 patients with refractory diabetic foot ulcers (DFUs) (>4 weeks' duration)
  • Digital planimetry† accurately captured DFU area, depth, and volume
  • Affinity significantly improved the incidence and time to wound closure (both P<0.05)

Significantly more DFUs were closed with Affinity than SOC at 8, 12 and 16 weeks (P=0.04)1

Frequency of wound closure‡

36% DFUs closed at 8 weeks with Affinity vs 23% with SOC. 60% DFUs closed at 12 weeks with Affinity vs 38% with SOC. 63% DFUs closed at 16 weeks with Affinity vs 38% with SOC.

*Debridement, infection elimination, dressings, and offloading by total contact casting. †Silhouette® laser-assisted wound measurement device. ‡Estimated frequency of wound closure at weeks 8, 12 and 16; estimated from Cox adjusted survival data for wound closure.

Median time to DFU closure with Affinity was 11 weeks. SOC failed to attain this endpoint at 16 weeks.1

Significantly more DFUs achieved >60% reduction in wound area (P=0.02) and depth (P=0.04) and >75% reduction in volume (P=0.06) with Affinity than SOC1

82% DFUs achieved >60% reduction in wound area vs 58% with SOC. 81% DFUs achieved >75% reduction in volume vs 58% with SOC.

Real-world evidence

Affinity, as a protective wound covering, has been shown to reduce wound area and support closure in a wide variety of wounds from head to toe.2-4
