Topical Pirfenidone

Centro Dermatológico Dr. Ladislao de la Pascua · Phase 3 active Small molecule Under review

Topical Pirfenidone is a Antifibrotic Small molecule drug developed by Centro Dermatológico Dr. Ladislao de la Pascua. It is currently in Phase 3 development for Idiopathic pulmonary fibrosis. Also known as: KitosCell.

Pirfenidone is an antifibrotic agent that inhibits the production of transforming growth factor-beta (TGF-β), a key cytokine involved in fibrosis.

Topical Pirfenidone is a small molecule with an unknown mechanism of action, used in various clinical trials for conditions such as scars, keloids, hypertrophic scars, keloid, and diabetic foot ulcers. It has been studied in comparison to silicon gel and other interventions in randomized controlled trials, including a pilot trial for the treatment of hypertrophic scars and keloids.

Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr
Health Canada CA 2029–2032 +0.9 yr
TGA AU 2029–2032 +1.2 yr
PMDA JP 2029–2032 +1.5 yr

Mechanism of action

Pirfenidone works by inhibiting the activation of TGF-β, which in turn reduces the production of extracellular matrix proteins and the proliferation of fibroblasts. This leads to a decrease in fibrosis and inflammation. Additionally, pirfenidone has been shown to have antioxidant properties, which may also contribute to its antifibrotic effects.
