Also as part of the new strategic collaboration agreement, Bristol-Myers Squibb will independently conduct and fund a Phase 1/2 dose optimization and expansion study in first-line non-small-cell lung cancer with bempeg and nivolumab.
Emphasis added.
In the original agreement, BMY didn't do anything with NKTR-214 independently.
