TRx Pharma is gearing up to launch a new product to combat flu and influenza.

Called Zanafu, it is a compound that TRx licensed from Adventrx Pharmaceuticals in San Diego, Calif. TRx acquired the rights last October.

The product’s brand name was disclosed Monday.

TRx has already paid Adventrx a $500,000 licensing fee, and another $500,000 is expected to be paid in June.
