Detailed Description
The study to evaluate the safety, tolerability, pharmacokinetics and efficacy of TFX05-01 in patients with advanced solid tumors, which was divided into dose exploration part (Phase Ⅰ) and indication exploration part (Phase Ⅱa). Each Phase of the study consisted of a screening period (21 days before initial dosing), a treatment period (from the first trial to the onset of an endpoint event), and a follow-up period.

Outcome Measures
Primary Outcome Measures
- Safety and Tolerability [Through study completion (About two years)]
Safety and tolerability of TFX05-01 as characterized by type, frequency, severity, timing and relationship to study therapy of adverse events and laboratory abnormalities according to CTCAE v5.0.
- Maximum tolerated dose (MTD) [Through the end of the first cycle (Days 1-21)]
MTD as determined by percentage of participants with dose limiting toxicities (DLTs).
- Recommended Phase 2 Dose (RP2D) [Through study completion (About two years)]
RP2D as determined by percentage of participants with DLTs and cumulative safety.
Secondary Outcome Measures
- Pharmacokinetics (PK) - Time to maximum concentration (Tmax) [Throughout Days 1 and 8 of Cycle 1 and Days 1 of Cycle 2-N (21 days for each cycle)]
Tmax of TFX05-01 will be computed for each subject where possible.
- PK - Maximum peak plasma concentration (Cmax) [Throughout Days 1 and 8 of Cycle 1 and Days 1 of Cycle 2-N (21 days for each cycle)]
Cmax of TFX05-01 will be computed for each subject where possible.
- PK - Terminal Elimination Half-life (T1/2) [Throughout Days 1 and 8 of Cycle 1 and Days 1 of Cycle 2-N (21 days for each cycle)]
T1/2 of TFX05-01 will be computed for each subject where possible.
- PK -Area under the plasma concentration versus time curve (AUC) [Throughout Days 1 and 8 of Cycle 1 and Days 1 of Cycle 2-N (21 days for each cycle)]
AUC of TFX05-01 will be computed for each subject where possible.
- The overall response rate (ORR) [Through study completion (About two years)]
ORR will be estimated based on the proportion of evaluable patients whose overall response (ORR) during study treatment is CR or PR. Disease response will be assessed by the investigator using RECIST v1.1.
- Duration of response (DoR) [Through study completion (About two years)]
DoR assessed by RECIST 1.1 criteria.
- Disease control rate (DCR) [Through study completion (About two years)]
DCR assessed by RECIST 1.1 criteria.
- Progression free survival (PFS) [Through study completion (About two years)]
PFS assessed by RECIST 1.1 criteria.
- Overall survival (OS) [Through study completion (About two years)]
The time from randomization to death for any reason.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Male or female participants ≥ 18 years of age at the time of screening. And participants ≤75 years of age for phase Ⅰ.
