CytRx said last week that it has exclusively licensed its phase III sickle cell disease drug Flocor, as well as its OptiVax vaccine delivery technology, to SynthRx, a Houston-based startup firm founded and run by Robert Hunter, a CytRx co-founder and chairman of the University of Texas’ department of pathology and laboratory medicine.

The out-licensing of these assets, leftovers from before CytRx acquired Global Genomics and reorganized under president and CEO Steve Kriegsman, has been a goal of the company for some time.
