Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Arm A (mFOLFIRINOX); JPI-547 and Combination Chemotherapy(mFOLFIRINOX) The study is conducted in a 3+3 dose escalation method.	Drug: JPI-547; Subjects are administered this investigational product once a week for 5 days, and have wash-out period for 2 days (5 Days on-2 Days off).; The investigational product is administered orally in a fasting state for 2 hours before and after meals at the same time (e.g., a certain time in the morning).; Capsules should be swallowed whole and should not be chewed, crushed or split.; Drug: modified FOLFIRINOX; After IV administration of Oxaliplatin 65 mg/m2 for 2 hours; After IV administration of Leucovorin 400 mg/m2 for 2 hours + IV administration of Irinotecan 135 mg/m2 for 90 minutes (Irinotecan is started 30 minutes after the start of Leucovorin administration and administered simultaneously during the last 90 minutes of Leucovorin administration, but administered separately using a Y-connector without mixing); Continuous IV infusion of 5-FU 2400 mg/m2 for 46 hours; Repeated administration every 2 weeks on a 14-day cycle

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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)

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
