A Study to Evaluate Safety, PK and Efficacy of HS-10296 in Patients With NSCLC

A Phase 1/2, Open-label, Multicenter Study to Evaluate Safety, Tolerability, Pharmacokinetics and Efficacy of HS-10296 in Patients With Locally Advanced or Metastatic Non-Small-Cell Lung Cancer

This is a Phase 1/2, open-label, multicenter study of HS-10296 with dose escalation, dose expansion and extension cohorts in locally advanced or metastatic non-small-cell lung cancer (NSCLC) patients who have progressed following prior therapy with an epidermal growth factor receptor(EGFR) tyrosine kinase inhibitor (TKI) agent. The study is designed to evaluate safety, tolerability, pharmacokinetics (PK), and anti-tumor activity of once-daily and orally (PO) administered HS-10296. The overall study design is shown in the flow chart below, which consists of 3 phases: dose escalation, dose expansion and extension cohort.

Overall Response Rate (ORR) Phase II Part	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 6 weeks later, as assessed according to RECIST (Response Evaluation Criteria In Solid Tumors Criteria) version 1.1 for target lesions and assessed by CT/MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.	From the date of first dose until the date of disease progression or withdrawal from study, approximately 15 months
Incidence and Severity of Adverse Events (AEs) Phase I Part	An AE is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. An undesirable medical condition can be symptoms (e.g., nausea, chest pain), signs (e.g., tachycardia, enlarged liver), or the abnormal results of an investigation (e.g., laboratory findings, ECG). Any deterioration of the disease under study and associated symptoms or findings should not be regarded as an AE as far as the deterioration can be anticipated. The AE was graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE), Version 4.0.	From the screening period to 28 days after treatment completion, approximately 16 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area Under the Plasma Concentration Versus Time Curve (AUC) of HS-10296 and HAS-719 From Zero to the 24-Hour Sampling Time (AUC0-24) After Single Dose of HS-10296	Area under the plasma concentration versus time curve from time zero to the 24-hour sampling time 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.	From pre-dose to 24 hours after single dose on Day 1 of Cycle 0
Elimination Half-life(T1/2) of HS-10296 and HAS-719	Elimination half-life is the time measured for the concentration to decrease by one half. Half-life calculated by natural log 2 divided by λz.	From pre-dose to 120 hours after single dose on Day 1 of Cycle 0
Css Max of HS-10296 and HAS-719 After Multiple Dose	Observed maximum plasma concentration (Css max) after multiple dose of HS-10296 and HAS-719	From pre-dose to 21 days after multiple dose on Day 1 of Cycle 2
AUCss of HS-10296 and HAS-719 After Multiple Dose of HS-10296	Area Under the Plasma Concentration Versus Time Curve at steady state (AUCss) of HS-10296 and HAS-719 after multiple dose of HS-10296	From pre-dose to 21 days after multiple dose on Day 1 of Cycle 2
Overall Response Rate (Phase I Part)	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 6 weeks later, as assessed according to RECIST (Response Evaluation Criteria In Solid Tumors Criteria) version 1.1 for target lesions and assessed by CT/MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.	From the date of first dose until the date of disease progression or withdrawal from study, approximately 15 months
Progression-free Survival (PFS)	The PFS is defined as the time from date of first dosing until the date of objective disease progression as defined by Response Evaluation Criteria in Solid Tumors （RECIST） v1.1 or death (by any cause in the absence of progression) regardless of whether the patients withdraws from HS-10296 therapy or receives another anti-cancer therapy prior to progression. Progression is defined as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.	From the date of enrollment until the date of disease progression or death from any cause, approximately 15 months
Disease Control Rate (DCR)	Objective response is assessed by RECIST 1.1 thereby to evaluate disease control rate. The DCR is defined as the proportion of patients with a best overall response of CR, PR, or SD (stable disease).	From the date of first dose until the date of disease progression or withdrawal from study, approximately 15 months
Overall Survival (OS) Phase II Part	Overall survival will be assessed based on the date of first dose and survival status at the time of analysis. Overall survival is defined as the time from date of first dose until the documentation of death from any cause.	From the date of enrollment until the date of death from any cause, approximately 48 months
Depth of Response (DepOR)	Depth of Response (DepOR) Only in part II dose-extention phase. DepOR is defined as the percentage change in tumor size, based on longest diameter or reconstructed volume, observed at the lowest point compared with baseline.	From the date of enrollment until the date of disease progression or death, approximately 15 months
Duration of Response (DoR)	Duration of response (DoR) is defined as the time from the date of first documented response until the date of documented progression or death in the absence of disease progression. The end of response should coincide with the date of progression or death from any cause used for the PFS endpoint. The time of the initial response will be defined as the latest of the dates contributing towards the first visit response of PR or CR. If a patient does not progress following a response, then DoR will be used as the PFS censoring time.	From the date of enrollment until the date of disease progression or death, approximately 18 months
Incidence and Severity of AEs Phase II Part	An AE is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. An undesirable medical condition can be symptoms (e.g., nausea, chest pain), signs (e.g., tachycardia, enlarged liver), or the abnormal results of an investigation (e.g., laboratory findings, ECG). Any deterioration of the disease under study and associated symptoms or findings should not be regarded as an AE as far as the deterioration can be anticipated. The AE was graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE), Version 4.0.	From the screening period to 28 days after treatment completion, approximately 16 months
