MedKoo CAT#: 201050

CAS#: 117570-53-3

Description: Vadimezan, also known as DMXAA and ASA404, is a fused tricyclic analogue of flavone acetic acid with potential antineoplastic activity. Vadimezan induces the cytokines tumor necrosis alpha (TNF-alpha), serotonin and nitric oxide, resulting in hemorrhagic necrosis and a decrease in angiogenesis. This agent also stimulates the anti-tumor activity of tumor-associated macrophages.

Additional Information

Vadimezan or ASA404 (originally DMXAA) is a tumor-vascular disrupting agent (tumor-VDA) that attacks the blood supply of a cancerous tumor to cause tumor regression.  ASA404 was discovered by Bruce Baguley and William Denny and their teams at the Auckland Cancer Society Research Centre at the University of Auckland in New Zealand.[6] It was licensed to Antisoma in 2001. Novartis acquired the worldwide rights for it in 2007 and it is being developed by Antisoma and Novartis. See wikipedia.
Novartis announced today (November 11, 2010) that the clinical trial program for the investigational cancer treatment ASA404 (vadimezan) will be discontinued and resources will be reallocated to other compounds in the oncology pipeline. The decision was made after interim results from a Phase III trial showed that ASA404 would not likely meet the primary endpoint of significantly extending overall survival when used in combination with chemotherapy for the second-line treatment of patients with advanced non-small cell lung cancer (NSCLC).
