Brief Summary
This trial will include 2 portions (phase 1 and phase 2). The first portion will be a Phase I, open label, dose escalation study to establish the maximum tolerated dose (MTD) of XB2001 as measured by Dose-Limiting Toxicity (DLT), in combination with ONIVYDE + LV + 5-FU chemotherapy regimen in patients with advanced pancreatic cancer and to determine the recommended dose for the subsequent Phase 2 study. The phase 2 portion will be implemented with the maximum established tolerated dose (MTD) of XB2001. The target enrollment in the phase 2 portion is 60 patients which will be randomized on a 1:1 basis to XB2001 plus ONIVYDE + LV + 5-FU (Arm 1) or placebo plus ONIVYDE + LV + 5-FU (Arm 2).

Outcome Measures
Primary Outcomes (2)
To Establish the Maximum Tolerated Dose (MTD) of XB2001 as Measured by Dose-Limiting Toxicity (DLT), in Combination With ONIVYDE + LV + 5-FU Chemotherapy Regimen in Patients With Advanced Pancreatic Cancer.
The primary objective of the Phase I portion is to identify the MTD of XB2001 when administered in combination with ONIVYDE + LV + 5-FU. The MTD is defined as the highest dose level at which no more than one out of six subjects experience a DLT. If two or more subjects in a cohort of six experience a DLT, the MTD is considered exceeded, and the previous lower dose level will be identified as the MTD. If no DLTs are observed at the highest dose level studied, that dose will be used for Phase II. A DLT is defined as any Grade 3-4 adverse event (per NCI CTCAE v5.0) occurring within the first 28 days that is deemed possibly related to the combination regimen, unless the toxicity is clearly attributable to a single non-XB2001 component. Specific DLT criteria include: 1. Inability to deliver all scheduled doses during the 28-day window due to unexpected drug-related toxicity. 2. Inability to deliver the intended dose of XB2001 due to drug-related toxicity.
28 days (consisting of the first two 14-day treatment cycles or the formal DLT observation window).
Safety and Tolerability of XB2001 in Combination With ONIVYDE + LV + 5-FU
This endpoint evaluates the cumulative safety profile and patient tolerance of XB2001 when administered at the Maximum Tolerated Dose (MTD) or the maximum dose studied in Phase I, in combination with the ONIVYDE + LV + 5-FU regimen. Safety is characterized by the total number of participants in each cohort who experienced one or more adverse events. For the purpose of this count, each participant is counted only once, regardless of the total number of individual adverse events experienced.
From post-infusion visit 1(week 0) through visit 13 (week 24), which is two weeks after the last infusion.
Secondary Outcomes (9)
Progression Free Survival (PFS)
From baseline until the date of first documented disease progression or date of death (from any cause), whichever come first.
Overall Survival (OS)
From baseline until death from any cause
Objective Response Rate (ORR)
Analyses performed at Visit 5 (Week 8), Visit 9 (Week 16), and Visit 13 (Week 24). This outcome measure was reported for Visit 13.
Time to Treatment Failure(TTF)
From baseline until treatment failure assessed up to Visit 13 (Week 24)
Number of Serious Adverse Events (SAEs)
From post-infusion visit 1(week 0) through visit 13 (week 24), which is two weeks after the last infusion.

Study Arms (2)
Phase I: Dose Escalation Phase
EXPERIMENTALIn Phase I (Dose escalation phase), 3 sequential dose levels were administered by participants; 250 mg (dose cohort 1), 500 mg (dose cohort 2), and 1000 mg (dose cohort 3), and traditional 3:3 design was used. Dose-escalation will continue if none of three subjects experience a dose-limiting toxicity (DLT). After enrollment participants received two treatment cycles (a total of 28 days) in which they were given one intravenous (IV) dose of XB2001 prior to receiving ONIVYDE 70 mg/m2 IV over 90 minutes, followed by leucovorin 400 mg/m2 IV over 30 minutes, followed by 5-Fluorouracil 2400 mg/m2 intravenously over 46 hours at each cycle.
Phase II: Dose Expansion Phase
EXPERIMENTALIn Phase II (dose expansion phase), participants were randomized in 1:1 fashion and received: 1. XB2001 1000 mg combination with ONIVYDE, Leucovorin, and 5-Fluorouracil 2. Placebo 1000 mg in combination with ONIVYDE, Leucovorin, and 5-Fluorouracil
Interventions
Subjects were administered one intravenous (IV) dose of placebo 1000 mg prior to receiving ONIVYDE 70 mg/m2 IV over 90 minutes, followed by leucovorin 400 mg/m2 IV over 30 minutes, followed by 5-Fluorouracil 2400 mg/m2 intravenously over 46 hours at each cycle.
Subjects were administered one intravenous (IV) dose of XB2001 500 mg prior to receiving ONIVYDE 70 mg/m2 IV over 90 minutes, followed by leucovorin 400 mg/m2 IV over 30 minutes, followed by 5-Fluorouracil 2400 mg/m2 intravenously over 46 hours at each cycle.
