I am excited to share my trip to Australia and introduce STELFONTA® (tigilanol tiglate)! What is STELFONTA® (tigilanol tiglate)? It is a new intratumor anticancer agent for mast cell tumors in dogs. It is isolated from the seed of Fontainea picrosperma, or the blushwood fruit, which is only found in the rainforest of Australia. It is a Protein Kinase C activator and stimulates rapid tumor destruction and site healing with good cosmetic outcome usually within 28 days. It causes direct oncolysis on the first day, then a tumor vascular necrosis and slough on day 4 and tumor destruction on day 7. There is a defect that heals typically without antibiotics and without bandage and intervention by day 28.
