Phase I Study to Evaluate Safety, Tolerability, Anti-Tumour Activity and PK Profiles of Foxy-5 in Metastatic Breast, Colon or Prostate Cancer

Phase I Dose Escalating Study to Evaluate the Safety, Tolerability, Anti-Tumour Activity and Pharmacokinetic and Pharmacodynamic Profiles of Foxy-5 in Patients With Metastatic Breast, Colon or Prostate Cancer

The Wnt proteins belong to a family of proteins that have been demonstrated to play a role in the formation and dissemination of tumours. The present project focuses on the critical role of the Wnt-5a protein in the pathobiological processes that lead to metastatic cancer disease.

WntResearch has identified a formylated 6 amino acid peptide fragment, named Foxy-5, which mimick the effects of Wnt-5a to impair migration of epithelial cancer cells and thereby acting anti-metastatic. The aim of the present clinical phase 1 trial is to establish the recommended dose for a clinical phase 2 study and thereby further develop Foxy-5 as a first in class anti-metastatic cancer drug. Foxy-5 is designed to inhibit the development of metastasis by reducing the motility of cancer cells and should thereby increase the survival rates of patients with solid malignant tumours.
