Arm && Interventions

Group	Intervention	Description
TT-00973-MS Tablets	TT-00973-MS tablets treatment	TT-00973-MS tablets will be administered at the starting dose of 2mg. Subsequently, patients will be enrolled according to the standard 3+3 dose escalation design.

Primary Outcome Measures

Name	Time	Method
Incidence of Dose Limiting Toxicity (DLT)	At the end Cycle 1(each cycle is 28 days)	To evaluate the incidence of DLT and determine the maximum tolerated dose.
Incidence of adverse events and sevious adverse events	Adverse events are collected from the patient's first dose of TT-00973-MS until 28 days following the last dose of study drug.	To evaluate the safety and tolerability of TT-00973-MS tablets administered orally in patients with advanced solid tumors. NCI CTCAE 5.0 grading system will be used to determine the severity.

Secondary Outcome Measures

Name	Time	Method
Time to reach maximum plasma concentration (Tmax)	Pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120 hours post-dose on Day 1 single dose;pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24 hours post-dose on Day 28 of Cycle 1
terminal half-life (T1/2)	Pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120 hours post-dose on Day 1 single dose;pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24 hours post-dose on Day 28 of Cycle 1
Progression-free survival(PFS)	Until the date of documented confirmed relapse/progression or death, whichever occurs first, assessed up to 1 year.	PFS will be calculated from the date of first dose to the date of documented confirmed relapse/progression or death, whichever occurs first.
Peak plasma concentration (Cmax)	Pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120 hours post-dose on Day 1 single dose; pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24 hours post-dose on Day 28 of Cycle 1
Area under the plasma concentration versus time curve (AUC)	Pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120 hours post-dose on Day 1 single dose; pre-dose, 0.5, 1, 2, 4, 6, 8, 12, 24 hours post-dose on Day 28 of Cycle 1
Objective response rate(DCR)	Up to approximately 1 year	DCR is defined as the rate of CR, PR and SD.
Duration of response(DOR)	Up to approximately 1 year	DOR will be calculated as the date of the first documented CR/PR to the date of the first documented confirmed relapse or death, whichever occurs first.
Objective response rate(ORR)	Up to approximately 1 year	ORR is defined as the rate of CR and PR.
Overall survival(OS)	Up to approximately 1 year	Overall survival is defined as the time from first dose to the date of death due to any cause.
