Advexin moves closer to market
7/4/2008 web-based article Matthew Dennis cancerdrugnewsblog.blogspot.com Introgen Therapeutics has submitted a BLA to the FDA, while simultaneously Gendux Molecular (Introgen) has submitted an MAA to the EMEA, both seeking marketing approval for Advexin (INGN 201), the company's targeted p53 tumour suppressor gene therapy, to treat recurrent, refractory head and neck cancer. INGN 201 represents the first in a new class of tumour suppressor cancer therapy and is the first of its kind to be submitted for regulatory approval in the US and Europe. Introgen has requested priority review from the FDA for INGN 201, meaning that the treatment could be on the market in early 2009. INGN 201 therapy harnesses the body's natural tumour suppression mechanisms to fight cancer, without the toxicities associated with conventional cancer treatments. Abnormalities in protective tumour suppressor p53 pathways are associated with the majority of all solid cancers. Designed to restore patients' ability to fight cancer, INGN 201 delivers large doses of the normal p53 gene to target abnormal p53 function present in tumour cells, which triggers natural tumour suppression mechanisms in cancer without harming normal cells. According to Dr Jack Roth, inventor of Advexin and professor at the University of Texas MD Anderson Cancer Center: "This is an important milestone in the clinical application of gene therapy for cancer patients. With the use of p53 biomarkers, Advexin will provide more effective and less toxic treatment for head and neck cancer patients who have limited treatment options." The submissions are based on pivotal Phase II [...]
