This is a Phase Ia/Ib open-label, dose-escalation study to evaluate the safety and pharmacokinetics of ROSE12 as a single agent and in combination with other anti-tumor agents in patients with locally advanced or metastatic solid tumors. The study will consist of three parts: a dose-escalation part, a biopsy part (the part to evaluate biomarkers), and an expansion part.

* Active or history of clinically significant autoimmune disease
* History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins.
\[Expansion Part\]
* Prior treatment with investigational product which has MoA of Treg depletion
* Malignancies other than disease under study within 5 years prior to Cycle 1 Day 1
Primary outcome measure(s)
The maximum tolerated dose (MTD) and the recommended dose (RD) of ROSE12 when administered as a single agent and in combination with atezolizumab (Part A and C) — From Cycle 1 Day 1 until Cycle 1 Day 21 (Cycle 1 is 21 days) Incidence and nature of dose-limiting toxicities (DLTs)
Safety (All Parts) and tolerability (Part A, B, C and D) of ROSE12 when administered as a single agent and in combination with atezolizumab or pembrolizumab (Adverse Events) — From screening until study completion, treatment discontinuation or post-treatment follow up, assessed up to the end of the study (approximate 43 months) Incidence, nature, and severity of adverse events graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0
The maximum serum concentration (Cmax) of ROSE12 for PK profile when administered as a single agent and in combination with atezolizumab or pembrolizumab (All Parts) — From Cycle 1 Day 1 (Cycle 1 is 21 days) until study completion or treatment discontinuation, assessed up to the end of the study (approximate 43 months) The maximum serum concentration (Cmax) of ROSE12
The minimum serum concentration (Cmin) of ROSE12 for PK profile when administered as a single agent and in combination with atezolizumab or pembrolizumab (All Parts) — From Cycle 1 Day 1 (Cycle 1 is 21 days) until study completion or treatment discontinuation, assessed up to the end of the study (approximate 43 months) The minimum serum concentration (Cmin) of ROSE12
The area under the concentration time-curve (AUC) of ROSE12 for PK profile when administered as a single agent and in combination with atezolizumab or pembrolizumab (All Parts) — From Cycle 1 Day 1 (Cycle 1 is 21 days) until study completion or treatment discontinuation, assessed up to the end of the study (approximate 43 months) The area under the concentration time-curve (AUC) of ROSE12
Preliminary anti-tumor activity of ROSE12 when administered in combination with atezolizumab or pembrolizumab (Part E and F) — From screening until study completion or treatment discontinuation, assessed up to the end of the study (approximate 43 months) Objective response rate (ORR), defined as the proportion of patients with an objective response (complete response \[CR\] or partial response \[PR\]) on two consecutive occasions ≥ 4 weeks apart, as determined by the investigator according to the Response Evaluation Criteria in Solid Tumors version 1.1
