What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Phase 1b: Maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D).	The MTD is determined according to the traditional 3+3 rule-based method for each combination therapy, and it is defined as the highest dose with a DLT incidence of less than 1/3 or 2/6 subjects.	From the date of administration to 4 weeks (DLT period)
Phase 2: To determine the regimen of JPI-547 in combination with Chemotherapy GemAbraxane and to evaluate the potential antitumor activity and safety of the combination therapy.		From first dose until disease progression, assessed up to end of study

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
To assess the adverse events, drug adverse events, and serious adverse events evaluated by NCI-CTCAE v5.0		Until 4 weeks after the last dose administration
To evaluate anti-tumor activity.	Anti-tumor activity is evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1	Evaluation at 8 weeks intervals through study completion from the date of study entry until the date of progression, up to 18 months
