Porcupine is a novel drug target that aims to address the issue of high unmet need in fibrosis.

Porcupine is a key enzyme in the WNT signalling pathway. WNT signalling has been implicated in fibrogenesis, and therefore inhibition of WNT signalling is likely to prevent several mechanisms important for fibrotic disease progression.

Current treatments for fibrosis are of limited benefit and there is an urgent need to develop new therapies to treat fibrotic conditions.

Several recent publications have shown that Porcupine (PORCN) inhibitors can be beneficial in the treatment of fibrotic indications, including renal, heart, lung and skin conditions.

Our team of scientists have demonstrated potent efficacy in mouse models of kidney, liver and lung fibrosis, and our candidate RXC006 is progressing through pre-clinical IND enabling studies.

By targeting this pathway, we aim to prevent progression or reverse fibrosis in patients with these devastating diseases.
