• Participants who have received prior anti-PD-1, anti-PD-L1, or anti-CTLA-4:

1. Must not have experienced a toxicity that led to permanent discontinuation of prior immunotherapy.

2. All AEs while receiving prior immunotherapy must have completely resolved or resolved to baseline

3. Must not have experienced a ≥ Grade 3 imAE or a neurologic or ocular imAE of any grade while receiving prior immunotherapy.

4. Must not have required the use of additional immunosuppression other than corticosteroids for the management of an AE

• Current or prior use of immunosuppressive medication within 14 days before the first dose of study drug. b. The following are exceptions to this criterion:

1. Intranasal, inhaled, topical steroids, or local steroid injections (eg, intra-articular injection).

2. Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent
