For Part 2 exclusively: While it is highly preferred to enroll subjects who are naïve to PD-1 inhibitors into a Part 2 dose escalation cohort, this is not an enrollment requirement. However, subjects who enroll into a Part 2 safety expansion cohort must be naïve to PD-1 inhibitors. If such subject is unable to meet this requirement but otherwise remains a good candidate for study enrollment, the Investigator should discuss with the Sponsor whether the subject may be enrolled |
