(1) prior studies which attempted to pegylate IL-2 failed; (2) the extended half-life of the Company’s lead I-O candidate, NKTR-214, was unlikely to result in efficacy and created additional high-dosing safety concerns; (3) NKTR-214 was less effective than IL-2 alone; (4) the combination of NKTR-214 with nivolumab has yet to demonstrate significant positive results; and (5) as a result, Nektar’s public statements as set forth above were materially false and misleading at all relevant times.
