• Men and women of childbearing potential (WOCBP) must be using an acceptable method of contraception to avoid pregnancy throughout the study, and for women at least 23 weeks after the last dose of investigational product and for men at least 31 weeks after the last dose of investigational product in such a manner that the risk of pregnancy is minimized
• Women must have a negative serum pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of investigational product

Exclusion Criteria

• Subjects with known or suspected brain metastasis, or brain as the only site of disease are excluded with the following exceptions
• Subjects with controlled brain metastasis (no radiographic progression at least 4 weeks following radiation and/or surgical treatment, off steroids for at least 4 weeks, and have no new or progressing neurological signs or symptoms) will be allowed
• Subjects with a history of prior malignancy with the exception of carcinoma in situ of the cervix or other malignancy diagnosed > 2 years ago that has undergone potentially curative therapy with no evidence of disease for the last >= 2 years and that is deemed by the investigator to be at a low risk of recurrence
• Active autoimmune disease or a history of known or suspected autoimmune disease with the exception of subjects with isolated vitiligo, treated thyroiditis or resolved childhood asthma/atopy
• Known human immunodeficiency virus (HIV), active hepatitis A, or hepatitis B or C infection
• Evidence of active infection that requires anti-bacterial, anti-viral, or anti-fungal therapy =< 7 days prior to initiation of study drug therapy
• History of acute diverticulitis within the last 6 months, or current chronic diarrhea
• Active peptic ulcer disease even if asymptomatic
• Prior organ allograft or allogenic bone marrow transplantation
• Uncontrolled or significant cardiovascular disease including, but not limited to, any of the following: * Myocardial infarction within the past 6 months * Uncontrolled angina within the past 6 months * Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation or Torsades de pointes); controlled atrial fibrillation by itself is not an exclusion criterion
• Baseline toxicities from prior anti-cancer treatments > grade 1
• Inability to be venipunctured and/or tolerate venous access
• Any major surgery within 4 weeks or a diagnostic procedure (e.g. incision, needle biopsy) within 1 day of study drug administration
• Known drug or alcohol abuse
• Presence of underlying medical condition that in the opinion of the investigator or sponsor could adversely affect the ability of the subject to comply with or tolerate study procedures and/or study therapy, or confound the ability to interpret the tolerability of combined administration of DS-8273A and nivolumab in treated subjects
• History of allergy to components of nivolumab or DS-8273A, or known allergy to other antibody therapies
• WOCBP who are unwilling or unable to use an acceptable method to minimize the risk of pregnancy for the entire study period and for at least 23 weeks after the last dose of investigational product
• Women who are pregnant or breastfeeding
• Women with a positive pregnancy test on enrollment or prior to investigational product administration
• Sexually active fertile men not using effective birth control if their partners are WOCBP
• Exposure to any investigational drug within 4 weeks of study drug administration
• Any anti-cancer therapy (e.g., chemotherapy, biologics, radiotherapy, or hormonal treatment) within 4 weeks or at least 5 half-lives (whichever is longer) of study drug administration
• Prior therapy with an anti-PD-1/PD-L1 antibody or a TRAIL-DR5 antibody
• Concurrent chemotherapy, hormonal therapy, immunotherapy regimens, or radiation therapy, standard or investigational
