UK’s Biotec­nol strikes a deal with CRUK to move new im­muno-on­col­o­gy drug in­to PhI

Lon­don-based Biotec­nol has struck a deal with Can­cer Re­search UK to move its lead im­mune-on­col­o­gy drug in­to an open-la­bel Phase I test. The pact lends the biotech CRUK’s help in see­ing whether its an­ti­body drug Tb535H works as planned: bind­ing to a tar­get anti­gen and then whip­ping up an im­mune re­sponse to at­tack can­cer cells.

The drug strat­e­gy is sim­ple. Their an­ti­body is de­signed to latch on to a pro­tein: the 5T4/WAIF1 tu­mor anti­gen. That in turn is sup­posed to flag an as­sault by CD8-pos­i­tive T cells, the kind of pri­ma­ry im­mune tac­tic that has been dri­ving a wide range of de­vel­op­ment projects in the can­cer field.
