Ansun BioPharma Announces Two Publications Showing Inhibitory Effects Of DAS181 On Respiratory Syncytial Virus (RSV) And Human Metapneumovirus (hMPV)

SAN DIEGO, Sept. 27, 2016 /PRNewswire/ -- Ansun BioPharma announced today the publication of two reports by researchers showing potent inhibitory effect of DAS181 on respiratory syncytial virus (RSV) and human metapneumovirus (hMPV).

"DAS181 Blocks Respiratory Syncytia Virus Infection of Hep-2 Cells" was published in the peer reviewed Journal of Antivirals & Antiretrovirals was published by Dr. Guy Boivin and colleagues at CHU de Quebec and Université Laval, Quebec City, QC, Canada. Respiratory Syncytial Virus (RSV) is one of the most common respiratory viruses affecting hospitalized and immunocompromised patients. Current therapeutic options are limited for the treatment of RSV. Strong inhibition of RSV by DAS181 was observed in the published in-vitro experiments. Lower concentrations of DAS181 were required to inhibit the virus, compared to Ribavirin, the only current approved treatment.

Additionally, another study was performed that showed that DAS181 showed activity against human metapneumovirus, a related respiratory virus. "Effect of Sialidase Fusion Protein (DAS 181) on Human Metapneumovirus (hMPV) Infection of Hep-2 Cells" was published by Dr. David Gordin and colleagues at Flinders University of Australia in the Journal of Antiviral Chemistry and Chemotherapy. The published data suggested potent in-vitro inhibition of Metapneumovus by DAS181. Metapneumovirus is a common respiratory virus in children and immunocompromised adults. Currently there are no treatments available for hMPV infections.

Dr. Ronald Moss, CEO of Ansun commented on the recent publications: "Although our current clinical focus is the testing of DAS181 against parainfluenza virus in immunocompromised patients, the potential to utilize the same antiviral against other respiratory viruses could be important. We are hoping to examine the clinical potential of DAS181 against RSV and hMPV in the near term."
