You may not qualify if…

• For the Triplet Cohort (Nivo/Ipi/HC-7366):
• Prior systemic treatment including neoadjuvant or adjuvant therapy including an immune checkpoint inhibitor or TKI 2. For the Doublet Cohort (Nivo/HC-7366):
• More than 3 prior lines of systemic therapy allowed
• Has received any type of small molecule kinase inhibitor (including investigational kinase inhibitor) ≤ 2 weeks before start of study drug or study therapy 3. ≤ 28 days before first dose of protocol-indicated treatment:
• Major surgery requiring general anesthesia 4. ≤ 14 days before first dose of protocol-indicated treatment:
• Radiosurgery or radiotherapy
• Minor surgery. (Note: Placement of a vascular access device is not considered minor or major surgery)
• Active infection requiring systemic treatment 5. Known or suspected clinically significant active bleeding including active hemoptysis 6. Inability to swallow oral medication; or the presence of a poorly controlled gastrointestinal disorder that could significantly affect the absorption of oral study drug - e.g. Crohn's disease, ulcerative colitis, chronic diarrhea (defined as > 4 loose stools per day), malabsorption, or bowel obstruction 7. Central nervous system (CNS) metastasis, unless asymptomatic and radiologically (by MRI) and clinically stable (i.e., without evidence of disease progression) for at least 4 weeks (28 days) by repeat imaging (repeat imaging should be performed during study screening), with no evidence of new or enlarging brain metastases, and without requirement for steroid treatment for at least 28 days prior to the first dose of study drug or study therapy. (CT is acceptable if MRI is contraindicated 8. Any condition requiring systemic treatment with either corticosteroids (> 10 mg/day prednisone or equivalent daily) or other immunosuppressive medications within 14 days prior to initiating protocol-indicated treatment
• In the absence of active autoimmune disease: Subjects are permitted the use of corticosteroids with minimal systemic absorption (e.g. topical, ocular, intraarticular, intranasal, and inhalational) ≤ 10 mg/day prednisone or equivalent daily; and physiologic replacement doses of systemic corticosteroids ≤ 10 mg/day prednisone or equivalent daily (e.g. hormone replacement therapy needed in participants with hypophysitis) 9. Active, known or suspected autoimmune disease
• Subjects with type I diabetes mellitus; hypothyroidism only requiring hormone replacement; skin disorders such as vitiligo, psoriasis or alopecia not requiring systemic treatment; or conditions not expected by the investigator to recur in the absence of an external trigger are permitted to enroll 10. Known psychiatric condition, social circumstance, or other medical condition reasonably judged by the investigator to unacceptably increase the risk of study participation; or to prohibit the understanding or rendering of informed consent or anticipated compliance with and interpretation of scheduled visits, treatment schedule, laboratory tests and other study requirements 11. Pregnant women are excluded from this study because HC-7366 is novel, first-in-class small molecule agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with HC-7366, breastfeeding should be discontinued if the mother is treated with HC-7366. These potential risks may also apply to other agents used in this study 12. Human immunodeficiency virus (HIV)-infected participants on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this study 13. Participants who are receiving any other investigational agents
