About DNX-2401

The company’s first product, DNX-2401, represents the culmination of over a decade of work and is the first oncolytic virus capable of killing cells with defects at any point in the retinoblastoma (Rb) pathway. DNX-2401 functions by replicating in, and killing tumor cells lacking growth control caused by any defect in the Rb pathway, without targeting a specific point in the pathway itself.  This property greatly lowers the risk of drug resistance and toxicity.  DNX-2401 is in clinical testing at University of Texas M.D. Anderson Cancer Center for treating glioblastoma multiforme, a type of stage IV brain tumor.  For more information about current clinical trials, please visit www.clinicaltrials.gov.

Glioblastoma multiforme (GB) is a fatal primary brain tumor resistant to conventional therapies. It is the second most common cause of death from intracranial disease, after stroke.  The current standard of care – surgery, radiotherapy and chemotherapy – has extended the overall median survival to only 14.6 months. GB is an unmet medical need with a clear need for new therapeutic modalities that can impact the course of the disease.

VLI was founded by David Curiel, M.D., Ph.D. while at Universityof Alabama, Birmingham.  The Company was funded by Greer Capital for developing novel cancer therapies based on the inventions of Dr. Curiel, Dr. Kovesdi and others.
