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).

Brief Title
XB2001 in Combination With ONIVYDE + 5-FU/LV (+Folinic Acid) in Advanced Pancreatic Cancer
Detailed Description
Study Title: A Phase I/II randomized, double-blind, placebo-controlled trial (1-BETTER) examining XB2001 (anti-IL-1⍺ True Human antibody) in combination with ONIVYDE + 5-FU/LV (+folinic acid) in advanced pancreatic cancer
Sponsor: XBiotech USA, Inc.
Sample Size: Approximately 69 patients will be enrolled in the USA (at least 9 patients in the open label phase 1 portion and 60 patients in the randomized phase 2 portion)
Approximate Duration:
This trial will include 2 phases. The first portion will be a Phase I, open label, dose escalation study evaluating the safety, tolerability and establishing the Maximum Tolerated Dose (MTD) of XB2001 in at least nine patients with metastatic pancreatic adenocarcinoma who are receiving ONIVYDE + Leucovorin l + d racemic + 5-Fluorouracil chemotherapy treatment. The duration for each patient in the Phase I portion will be 14 days (1 treatment cycle) in which they will be given one intravenous dose of XB2001 prior to receiving ONIVYDE + Leucovorin l + d racemic + 5-Fluorouracil chemotherapy treatment and assessed for Dose Limited Toxicities (DLT). The Phase II portion will be implemented following the completion of the Phase I portion and declaration of the MTD. The duration of subject participation in the randomized, double-blind, placebo-controlled Phase II portion of the trial is approximately 28 weeks: including a screening period of up to 30 days, and 24-week treatment period. All study subjects can continue treatment with XB2001 in an open label extension, for as long as they are judged to be benefitting clinically and have had no unacceptable toxicities.

Official Title
A Phase I/II Randomized, Double-blind, Placebo-controlled Trial (1-BETTER) Examining XB2001 (Anti-IL-1⍺ True Human Antibody) in Combination With ONIVYDE + 5-FU/LV (+Folinic Acid) in Advanced Pancreatic Cancer
Primary Outcomes
Outcome Description
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.

Outcome Measure
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.
Outcome Time Frame
28 days (consisting of the first two 14-day treatment cycles or the formal DLT observation window).
Outcome Description
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.

Outcome Measure
Safety and Tolerability of XB2001 in Combination With ONIVYDE + LV + 5-FU
Outcome Time Frame
From post-infusion visit 1(week 0) through visit 13 (week 24), which is two weeks after the last infusion.
Secondary Outcomes
Outcome Description
Progression free survival (PFS) was defined as the time from randomization to first progression based on RECIST v1.1 criteria or death from any cause, whichever occurred first. Subjects who had no baseline and post-baseline tumor assessment and no death, or no adequate post-baseline tumor assessment and no death were censored at the date of randomization. Subjects alive and without documented disease progression at the time of data analysis are censored at the date of the last adequate tumor assessment.
Outcome Time Frame
From baseline until the date of first documented disease progression or date of death (from any cause), whichever come first.
Outcome Measure
Progression Free Survival (PFS)
Outcome Description
OS was defined as the duration from the date of randomization until death irrespective of the cause. Subjects who were alive at the time of analysis were censored at the last known date alive. Subjects without any data after baseline were censored on the randomization day.
Outcome Time Frame
From baseline until death from any cause
Outcome Measure
Overall Survival (OS)
Outcome Description
Objective Response Rate (ORR) is defined as the proportion of subjects in the Phase II Population who achieved a Best Overall Response (BOR) of either Complete Response (CR) or Partial Response (PR), as defined by RECIST v1.1 criteria.
Outcome Time Frame
Analyses performed at Visit 5 (Week 8), Visit 9 (Week 16), and Visit 13 (Week 24). This outcome measure was reported for Visit 13.
Outcome Measure
Objective Response Rate (ORR)
Outcome Description
TTF measures the time from randomization to discontinuation of treatment for any reason, including, but not limited to, disease progression, treatment-related toxicity, and/or death during study.
Outcome Time Frame
From baseline until treatment failure assessed up to Visit 13 (Week 24)
Outcome Measure
Time to Treatment Failure(TTF)
Outcome Description
This outcome measure calculates the total number of unique participants who reported serious adverse events (SAEs) in each group. An SAE is defined as any untoward medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect.
Outcome Time Frame
From post-infusion visit 1(week 0) through visit 13 (week 24), which is two weeks after the last infusion.

Outcome Description
This measure tracks the overall burden of severe (Grade 3) or life-threatening (Grade 4) diarrhea as defined by the NCI CTCAE v5.0. Grade 3 events are severe enough to require medical intervention or significantly limit a person's ability to care for themselves, while Grade 4 events represent urgent, life-threatening clinical situations.
Outcome Time Frame
From post-infusion visit 1(week 0) through visit 13 (week 24), which is two weeks after the last infusion.
Outcome Measure
Incidence of Grade 3-4 Diarrhea
Outcome Description
This outcome measure calculates the sum of duration of hospitalizations during the study period in phase II population for both groups.
