What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Dose-Escalation Stage: RP2D for TAC-001	To identify the recommended dose phase 2 dose (RP2D) for further evaluation of TAC-001 when administered as monotherapy in subjects with advanced or metastatic solid tumors	2-years
Dose Expansion: Characterization of ORR for TAC-001	To evaluate preliminary efficacy of TAC-001 by estimating the overall response rate (ORR; combined complete response [CR] and partial response [PR]) as assessed by the Investigator per RECIST 1.1 and iRECIST	2 years
Dose Expansion: Characterization of duration of response for TAC-001	To evaluate preliminary efficacy of TAC-001 by estimating the duration of response as assessed by the Investigator per RECIST 1.1 and iRECIST	2 years
Dose Expansion: Characterization of clinical benefit rate for TAC-001	To evaluate preliminary efficacy of TAC-001 by estimating the clinical benefit rate as assessed by the Investigator per RECIST 1.1 and iRECIST	2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidence and Severity of Nonserious Adverse Events (AEs) and Serious Adverse Events (SAEs)	To evaluate the safety of TAC-001 monotherapy through the evaluation of incidence and severity of nonserious AEs and SAEs, including immune-related adverse events (irAEs), as graded by investigators according to CTCAE version 5.0	2 years
Maximum Plasma Concentration (Cmax)	To evaluate the Cmax of TAC-001 monotherapy	2 years
Maximum Plasma Concentration (Tmax)	To evaluate the Tmax of TAC-001 monotherapy	2 years
Area Under the Plasma Concentration-Time Curve (AUC)	To evaluate the AUC of TAC-001 monotherapy	2 years
Terminal Half-Life	To evaluate the terminal half-life of TAC-001 monotherapy	2 years
Clearance of TAC-001	To evaluate the drug clearance of TAC-001 monotherapy	2 years
Evaluation of immunogenicity of TAC-001	Incidence of antidrug antibodies (ADA) against TAC-001	2 years
