Primary Outcome Measures

Name	Time	Method
Phase Ib: Safety and Tolerance	Safety and tolerance assessments continued for the duration of treatment. AEs and SAEs will be collected from time of signature of main informed consent, throughout the treatment period and including the follow-up period, up to approximate 22 months.	An AE was any untoward medical occurrence after clinical study subjects receive study drug. An SAE was any event that meets any the following criteria: death, life-threatening; inpatient hospitalization or prolongation, persistent or significant disability/incapacity;congenital malformation/birth defects and significant medical events. AE and SAE were graded by CTCAE version 5.0 by severity, from Grade 1 mild to Grade 5 death related AE.
Phase Ib: Patients With Event(s) of Dose-limiting Toxicity	Cycle 1 (21 days) of treatment	Number of DLT (Dose-limiting toxicity) During the Administration of BLU-554 in Combination with CS1001. All toxicity or adverse events (AEs) are graded according to NCI-CTCAE 5.0. Any AE occurring during C1 (21 days) that is not clearly caused by something other than investigational drug.
Phase II: Objective Response Rate (ORR) Assessed by Investigator Based on RECIST Version 1.1	Imaging (CT or MRI) assessments per RECIST v1.1 will be performed within 28 days prior to the first dose (baseline assessment), every 9 weeks during the first year of the study, and every 12 weeks thereafter. Up to 22 months.	Per Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1 .1) for target lesions and assessed by MRI/ CT: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \> =30% decrease in the sum of the longest diameter of target lesions; Objective Response (OR) = CR + PR. Percentage of subjects who achieve objective tumor response (CR or PR) will be summarized.
