Maximum Tolerated dose (MTD) and Recommended phase 2 dose as determined by Dose limiting Toxicity (DLT).

|
PFS rate at 24 weeks
Time Frame: within first 2 4weeks of treatment

Overall Survival (OS)
Time Frame: 6 months after the last treatment of the last subject
|
Defined from the date of treatment assignment until the date of death due to any cause.
Any participant not known to have died at the time of analysis will be censored based on the last recorded date on which the participant was known to be alive.
|
6 months after the last treatment of the last subject
|
Objective Response Rate (ORR)
Time Frame: 6 months after the last treatment of the last subject
|
Defined as the proportion of participants with measurable disease who achieve complete response(CR) or partial response(PR), as determined by the Investigator per RECIST v1.1.
Data obtained up until disease progression, or the last evaluable assessment in the absence of progression, will be included in the assessment of ORR.
Confirmatory scan is needed for the patients with CR or PR after 4 weeks of the first response.
Participants who discontinue treatment without progression, receive a subsequent therapy, and then respond, will not be included as responders in the ORR.
|
6 months after the last treatment of the last subject
|

Time Frame: 6 months after the last treatment of the last subject
|
Defined as the percentage of participants who have a confirmed CR or PR or who have SD (without subsequent cancer therapy) after the date of treatment assignment.
|
6 months after the last treatment of the last subject
|

|
6 months after the last treatment of the last subject
|
Progression-free survival (PFS)
Time Frame: 6 months after the last treatment of the last subject
|
Defined as time from the date of treatment assignment until progression per RECIST v1.1 as assessed by the Investigator, or death due to any cause.
Participants who have not progressed or died at the time of analysis will be censored at the time of the latest date of assessment from their last evaluable RECIST v1.1 assessment.
