$AGEN is dead money as its PD-1 and CTLA-4 are too late. Already on market  PD-1: Keytruda $MRK , Opdivo $BMY; PD-1L Tecentriq $RHHBY Bavencio $MRK Imfinzi $AZ .   $AGEN CTLA-4 may be second gen, but interest has moved on to CD47 and TIGIT/ PVRIG  Stock had pop AH, but now faded. https://t.co/v2qnAwOm18
