Brief summary: This study is a multicenter, open-label, phase 1 study to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of TT-00973-MS tablets in patients with solid tumors.

Detailed description: A modified 3+3 design will be used to determine the maximum tolerated dose(MTD) during dose escalation period. Futher expansion period will enroll additional 12\~18 patients at the appropriate dose to futher evaluate the safety and preliminary efficacy of TT-00973-MS.

Eligibility criteria: Inclusion Criteria:

1. Subject is ≥ 18 years of age
2. Histologically or cytologically confirmed advanced malignant solid tumors, eligible patients have failed standard treatment, have no standard treatment, or are not suitable for standard treatment at this stage as determined by the investigator.
3. Must have at least one evaluable lesion in dose escalation period and one unidimensional measurable lesion according to RECIST version 1.1;
4. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1;
5. Life expectancy ≥3 months;
6. Patients must have adequate organ functions as indicated by the following screening laboratory values: ANC ≥ 1.5×10\^9/L; PLT ≥ 75×10\^9/L; Hb ≥ 90 g/L; TBIL ≤ 1.5×ULN；ALT和AST ≤ 3×ULN(ALT and AST≤5×ULN for subjects with liver cancer or hepatic metastases); Cr ≤ 1.5×ULN or CLcr \>50mL/min(according to Cockcroft-Gault); APTT≤ 1.5×ULN; INR≤ 1.5×ULN.
7. Men and women of childbearing potential are willing to employ an effective method of contraception for the entire duration of study and 6 months after the last dose, and female subjects of childbearing potential have a negative pregnancy test at baseline.
