XB2001 in Combination With ONIVYDE + 5-FU/LV (+Folinic Acid) in Advanced Pancreatic Cancer

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

• Status: Active Not Recruiting
• Phase: Phase 1 / Phase 2
• Study type: Interventional

• Sponsor: XBiotech, Inc. · Industry
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

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).

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. Study Chair: David Park, M.D. 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.

Interventions

Type	Name	Description
BIOLOGICAL	XB2001 or Placebo	XB2001 is a True Human monoclonal antibody that blocks the biological activity of IL-1α with a high degree of affinity and specificity. IL-1⍺ is a key mediator of inflammatory responses and is implicated in the pathophysiology of various diseases, including cancer, cardiovascular and rheumatologic diseases. Ample evidence supports targeting IL-1⍺ to block pathological inflammatory processes associated with many diseases.
