Cotara binds to histone H1/DNA complexes exposed in the necrotic core of malignant solid tumors.

The agreements also include certain non-exclusive licenses for Peregrine's proprietary radiolabeling technologies and its fully-human NHS76 TNT antibody to enable and accelerate Stason's development of TNT products.
