"in humans?" YES! Peregrine has clinical data now for bavituximab in combination immunotherapy.
The first immunotherapy combination human trial was bavi with Yervoy. Peregrine has these data available for negotiating a sale or licensing of the IP, along with immuno combinations that occurred post SUNRISE. Many long investors know these facts. It may be that some aren't paying close attention to what has transpired in the clinic.
CAR-T anti-PS combination preclinical data has been published by Peregrine with the Wolchok MSK lab. One must keep one's ear to the ground...if one still has ears!
north40000, who keeps an ear to the ground, has had some communications with Dr. Wolchok related to a human combination trial with bavi and CAR-T. waiting for a go signal. This remains speculative, but if a CAR-T company is fingering the goods, they would want to run that trial, and others as well.
IMO
