HS-10241 is a highly potent and selective small molecule inhibitor of c-Met kinase. In preclinical studies, it demonstrated strong activity against c-Met kinase in vitro and in vivo, and inhibited tumor cell growth. This study is conducted to assess the maximum tolerated dose (MTD) and dose limiting toxicity (DLT), to evaluate the pharmacokinetics, safety and preliminary anti-tumor activity of HS-10241 at single dose and multiple doses.
This is a phase 1, open-label, multicenter study to evaluate safety, tolerability, pharmacokinetics, and efficacy of single and multiple doses of oral administration of HS-10241 in patients with locally advanced or metastatic solid tumors who have progressed following prior therapy. There is a dose-escalation study, which is designed to evaluate the safety, tolerability, and pharmacokinetics of single dose and repeat doses of HS-10241 given once every day (QD). An alternative dosing schedule of twice every day (BID) may be investigated if the drug clearance of HS-10241 is faster than anticipated. All patients will be carefully followed for adverse events during the study treatment and for 28 days after the last dose of study drug. Subjects of this study will be permitted to continue therapy with assessments for progression once every 6 weeks, if the product is well tolerated and the subject has stable disease or better. As the disease progresses, survival follow-up is recommended bimonthly.

MTD was defined as the previous dose level at which 2 out of 3 subjects or 2 out of 6 subjects experienced a DLT.
Time frame: From the single dose to the last dose of the first cycle defined as 21 days of multiple dosing (4 weeks).

In the study of single-dose, Cmax will be obtained following administration of a single oral dose of HS-10241 on Day 1 to Day 6.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 10, 12, 24,48, 72,120 hours post-dose on Day 1 single dose

Time to reach maximum plasma concentration (Tmax) after single dose of HS-10241
In the study of single-dose, Tmax will be obtained following administration of a single oral dose of HS-10241 on Day 1 to Day 6.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 10, 12, 24,48, 72,120 hours post-dose on Day 1 single dose
Time to reach maximum plasma concentration (Tmax) after multiple dose of HS-10241
At multiple-dose, Tmax will be obtained on Day 1 of dosing in the second 21-Day cycle of therapy.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 10, 12, 24 hours post-dose on Day 1 of dosing in the second 21-Day cycle of therapy
Apparent terminal half-life (t1/2) after single dose of HS-10241
Apparent terminal half-life is the time measured for the concentration to decrease by one half. Terminal half-life calculated by natural log 2 divided by λz.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 10, 12, 24,48, 72,120 hours post-dose on Day 1 single dose
Area under plasma concentration versus time curve from zero to the 24 hour sampling time (AUC0-24) after single dose of HS-10241
Area under the plasma concentration versus time curve from time zero to the 24 hour sampling time 24 at which the concentration was at or above the lower limit of quantification (LLQ). AUC0-24 was to be calculated according to the mixed log-linear trapezoidal rule.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 10, 12, 24,48, 72,120 hours post-dose on Day 1 single dose
Area under plasma concentration versus time curve from zero to last sampling time (AUC0-t) after single dose of HS-10241
Area under the plasma concentration versus time curve from time zero to the last sampling time t at which the concentration was at or above the lower limit of quantification (LLQ). AUC0-t was to be calculated according to the mixed log-linear trapezoidal rule.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 10, 12, 24,48, 72,120 hours post-dose on Day 1 single dose
Area under the plasma concentration versus time curve from time zero to infinity (AUC0-∞) after single dose of HS-10241
AUC0-∞ was calculated by combining AUC0-t and AUCextra. AUCextra represents an extrapolated value obtained by Clast/ λz, where Clast is the calculated plasma concentration at the last sampling time point at which the measured plasma concentration is at or above the LLQ and λz is the apparent terminal rate constant determined by log-linear regression analysis of the measured plasma concentrations of the terminal log-linear phase.
Time frame: Pre-dose, 0.5, 1, 1.5, 2, 4, 6, 8, 10, 12, 24,48, 72,120 hours post-dose on Day 1 single dose
To further evaluation of the anti-tumor activity of HS-10241 by assessment of objective response rate (ORR)
Anti-tumoral efficacy will be assessed by best radiographic response based on Response Evaluation Criteria in Solid Tumors at baseline (Day -28 to -1). For patients that continue on repeat 21-Day cycles after the primary evaluation period, progression will be assessed after each 6 weeks of therapy. ORR is defined as the percentage of patients with a complete response (CR) or partial response (PR) that was confirmed at a subsequent scan at least 4 weeks later, as assessed according to RECIST version 1.1.
Time frame: 0-360day
Duration of response of HS-10241
Duration of response assessed by RECIST 1.1. Duration of response was defined as the time from when the criteria for CR or PR were first met to the occurrence of a objective disease progression (PD) or death.
Time frame: 0-360day
Time to objective response of HS-10241
Objective response was assessed by RECIST 1.1.
Time frame: 0-360day
Disease control rate of HS-10241
Objective response was assessed by RECIST 1.1 thereby to evaluate disease control rate. Disease control was defined as the percentage of patients who have a best overall response (confirmd CR, PR, or stable disease for at least 5 weeks).
Time frame: 0-360day
Deepness of response of HS-10241
Objective response was assessed by RECIST 1.1 thereby to evaluate deepness of response. Depth of response was defined as the relative change in the sum of the longest diameters of RECIST target lesions at the nadir in the absence of new lesions, or progression of non-target lesions compared with baseline.
Time frame: 0-360day
