Abstract

BACKGROUND:

Changes associated with aging are partly due to loss of collagen and elastin. Treatment with autologous fibroblasts grown in culture (azficel-T) can help correct the appearance of aging by replacing lost dermal constituents.

OBJECTIVE:

To demonstrate the safety and effectiveness of autologous fibroblasts in the treatment of nasolabial fold (NLF) wrinkles.

METHODS AND MATERIALS:

Adults with moderate to very severe NLF wrinkles were randomized to receive three treatments with autologous fibroblasts or placebo at 5-week intervals. Blinded evaluators and subjects assessed efficacy using a validated wrinkle assessment scale.

RESULTS:

Three hundred seventy-two subjects were enrolled and underwent treatment. Seventy-eight percent of subjects treated with autologous fibroblast therapy and 48% of subjects treated with placebo achieved at least a 1-point improvement on the subject assessment at 6 months (p < 0.001), and 64% of subjects treated with autologous fibroblast therapy and 36% of those treated with placebo showed at least a 1-point improvement evaluator's assessment (p < 0.001). Adverse events were generally mild, and the treatment was well tolerated.

CONCLUSION:

Autologous fibroblast therapy is safe and effective for the treatment of NLF wrinkles. The availability of autologous cell therapy marks the beginning of a new phase in aesthetic therapy.
