• About us

Mariposa Therapeutics is dedicated to the discovery and development of therapies for keratin related diseases. Keratin is the main structural protein in your skin. It maintains its rigidity and helps with the barrier protection that the skin offers. 

Dysregulation of keratins gives rise to multiple diseases, characterised by loss of skin integrity, blistering and hyperkeratosis, and can predispose inflammatory disorders of internal organs. Together keratin-related diseases, including Epidermolysis Bullosa Simplex, Pachyonychia congenita and psoriasis, represent a huge disease burden for patients and their families. 

Mariposa’s first product MP5219 is a disease modifying therapeutic for the first keratinopathy to be identified – Epidermolysis Bullosa Simplex (EBS).

Vision

To give people with skin diseases and their families a normal, pain-free life.
