The subject must have progressed during or after the last treatment regimen or discontinued because of unacceptable toxicity. 5. Presence of at least 1 measurable lesion confirmed by BICR based on RECIST version 1.1. 6. Is willing and able to provide an adequate archival tumor tissue sample. A fresh biopsy is required if an archival tumor tissue sample cannot be supplied. Resection and core needle biopsy are acceptable. Other tissue samples, eg, fine needle aspirates or cell blocks are not acceptable. For detailed instruction on tissue submission, please refer to the laboratory manual. 7. Has ECOG PS of 0 to 1. 8. Has LVEF ≥ 50% within 28 days before randomization. 9. Has adequate organ function within 14 days before randomization, as defined in the protocol. 10. Has adequate treatment washout period before randomization, as defined in the protocol. 11. Male and female subjects of reproductive/childbearing potential must agree to use a highly effective form of contraception or avoid intercourse during and upon completion of the study and for at least 7 months for females and for 4 months for males after the last dose of study drug. Please refer protocol for more details. 12. Male subjects must not freeze or donate sperm starting at randomization and throughout the study period, and at least 4 months after the final study drug administration. Preservation of sperm should be considered prior to randomization in this study. 13. Female subjects must not donate, or retrieve for their own use, ova from the time of randomization and throughout the study treatment period, and for at least 7 months after the final study drug administration. Female subjects must refrain from breastfeeding hroughout this time. Preservation of ova may be considered prior to randomization in this study. 14. Life expectancy of 3 months or more.

Medical history of myocardial infarction within 6 months before randomization, symptomatic congestive heart failure (CHF) (New York Heart Association Class II to IV). Subjects with troponin levels above ULN at screening (as defined by the manufacturer), and without any MI related symptoms should have a cardiologic consultation before randomization to rule out MI. 3.

Has spinal cord compression or clinically active CNS metastases, defined as untreated and symptomatic, or requiring therapy with corticosteroids or anticonvulsants to control associated symptoms. Subjects with clinically inactive brain metastases may be included in the study. Subjects with treated brain metastases that are no longer symptomatic and who require no treatment with corticosteroids or anticonvulsants may be included in the study if they have recovered from the acute toxic effect of radiotherapy. A minimum of 2 weeks must have elapsed between the end of brain radiotherapy and study randomization. 6. Has multiple primary malignancies within 3 years, except adequately resected non melanoma skin cancer, curatively treated in-situ disease, or other solid tumors curatively treated. 7.

Subjects should be tested for HIV prior to randomization if required by local regulations or institutional review board (IRB)/independent ethics committee (IEC). 12. Known active clinically relevant liver disease (eg, active hepatitis B, or active hepatitis C), such as those with serologic evidence of viral infection within 28 days of Cycle 1, Day 1. Subjects with past or resolved hepatitis B virus (HBV) infection are eligible, if negative for hepatitis B surface antigen (HBsAg[-]) and positive for hepatitis B core antibody (anti-HBc[+]). Subjects positive for hepatitis C (HCV) antibody are eligible only if the polymerase chain reaction is negative for HCV RNA. 13. Unresolved toxicities from previous anticancer therapy, defined as toxicities (other than alopecia)not yet resolved to Grade ≤ 1 or baseline. Note: Subjects may be enrolled with chronic Grade 2 toxicities (defined as no worsening to > Grade 2 for at least 3 months prior to randomization and managed with standard of care treatment) which the investigator deems related to previous nticancer therapy, such as: a. Chemotherapy-induced neuropathy b. Fatigue c. Residual toxicities from prior IO treatment: Grade 1 or Grade 2 endocrinopathies which may include: • Hypothyroidism/ hyperthyroidism • Type I diabetes • Hyperglycemia • Adrenal insufficiency • Adrenalitis • Skin hypopigmentation (vitiligo) 14.
