A Study Comparing Whole-Body Heat Treatment Plus Systemic Therapy to Systemic Therapy Alone, for Advanced Pancreatic Cancer

Official title

A Multi-Centric, Randomized, Pivotal Study, Evaluating Efficacy and Safety of Whole-Body Hyperthermia Alongside Standard Systemic Anticancer Therapy in Patients With Metastatic Pancreatic Cancer After Failure of First Line Treatment.

Overview

Pancreatic ductal adenocarcinoma (PDAC) is associated with poor prognosis and limited treatment options following failure of first-line therapy. Whole-body hyperthermia (WBHT) is a non-invasive treatment approach that raises the body's core temperature under controlled conditions and may enhance the effects of anticancer therapies through multiple biological mechanisms, including improved drug delivery, modulation of the immune response, and increased sensitivity to treatment. The MATTERS-2 study is a multicentre, randomized clinical trial designed to evaluate the efficacy and safety of WBHT in combination with standard systemic anticancer therapy in patients with metastatic PDAC after failure of first-line treatment. Participants will receive either standard systemic therapy alone or standard systemic therapy combined with WBHT. The primary objective of the study is to determine whether the addition of WBHT improves clinical outcomes compared with standard therapy alone in terms of overall survival (OS) while maintaining safety. Secondary objectives include other clinical outcomes such as progression-free survival (PFS), disease control rate (DCR) and objective response rate (ORR). Further, quality of life assessments (QoL) and exploratory biomarker analyses will also be performed.

Interventions

• Device Whole-body hyperthermia
  Initially every 2 weeks, until a total of 3 treatments is reached. Thereafter every 4 weeks. The treatment will raise the body temperature to 41,50 °C for a total of 4 hours.
• Drug Standard-of-Care Systemic therapy
  Standard-of-care systemic therapy for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC, stage IV) after failure of first-line treatment.

Primary outcome measures

• Overall survival (OS) [Time frame: From randomization until death from any cause, assessed up to study completion (primary analysis triggered upon occurrence of 66 death events), an (expected) average of 12 months]
• Safety and tolerability of WBHT + SoC and SoC alone [Time frame: From moment of enrollment (ICF signature) up to End of Treatment visit, an (expected) average of 10 months]

Secondary outcome measures (6)

• Progression-free survival (PFS) [Time frame: Up to time of progression, death or study discontinuation; an (expected) average of 8 months]
• Disease control rate (DCR) [Time frame: Until death, end of treatment visit or study discontinuation; an (expected) average of 10 months]
• Objective response rate (ORR) [Time frame: Until death, end of treatment visit or study discontinuation; an (expected) average of 10 months]
• Quality of Life assessments (EORTC-QLQ-C30 version 3) [Time frame: Until death, end of treatment visit or study discontinuation; an (expected) average of 10 months]
• Quality of Life assessments (QLQ Pan 26) [Time frame: Until death, end of treatment visit or study discontinuation; an (expected) average of 10 months]
• Evolution of CA19-9 [Time frame: Until death, end of treatment visit or study discontinuation; an (expected) average of 10 months]

Exclusion criteria

• Other malignant diseases in the medical history during the last 5 years (exceptions: carcinoma in situ of the cervix or adequately treated basal cell carcinoma of the skin)
• Serious medical risk factors involving any of the major organ systems, including high cardiovascular risk defined as recent major cardiovascular events (such as myocardial infarction or stroke), clinically relevant heart failure due to structural or mechanical cardiac abnormalities (e.g., valvular disease or myocardial dysfunction), and clinically significant arrhythmias.
• Pathology that would interfere with the placement of the bladder catheter
• Clinically significant pulmonary disease which might interfere with mechanical ventilation
• History of autonomic dysfunction (due to the influence on skin blood flow)
• History of malignant hyperthermia
• History of untreated endocrine pathology (e.g. diabetes type II, hyper- or hypothyroidism).
• Primary untreated diabetes type I not related to the oncological condition (due to vascular complications).
• Known allergies to drugs that will be used during the trial (e.g. anesthetic, analgesic, chemotherapy)
