- Registration Number
- NCT06211933
- Lead Sponsor
- Centre Leon Berard
- Brief Summary
This is a phase I/II, multicenter trial for patients with locally advanced and unresectable pancreatic tumours :
* A Phase I evaluating the tolerance of intraoperative High Intensity Focused Ultrasound (HIFU) intervention on the pancreatic lesion.
...
- Detailed Description
The PULS study is designed for patients with a locally advanced tumour of the pancreas (known as pancreatic adenocarcinoma) that has previously been treated with several cycles of chemotherapy and cannot be removed by surgery.

Group Intervention Description HIFU intervention HIFU intervention HIFU intervention
- Primary Outcome Measures
Name Time Method Tolerance profile of HIFU intervention Up to 30 days after HIFU intervention The tolerance of HIFU intervention will be assessed by the number of patients presenting at least one serious complication during the first 30 days after HIFU intervention. A serious complication corresponds either to any grade 3 or more complication according Clavien-Dindo classification or any vascular complication treated by interventional radiology
Survival rate at 12 months after HIFU intervention Up to 12 months after HIFU intervention The efficacy of treatment will be assessed by the proportion of patients alive 12 months after HIFU treatment
- Secondary Outcome Measures
Name Time Method Intra-operative and post-operative complications linked to the HIFU intervention Up to 3 months after HIFU intervention The Intra-operative and post-operative complications linked to the HIFU intervention will be evaluated by the number of patients with at least one complication according to Clavien Dindo classification appeared during HIFU intervention and until 3 months after HIFU intervention
Feasibility of HIFU intervention Up to 28 days after inclusion The feasibility of HIFU intervention will be evaluated by the rate of patients who were able to benefit from HIFU intervention. The reasons for non-completion will be described.
Tumor ablation rate by HIFU Up to 28 days after inclusion The tumor ablation rate by HIFU is defined by the volume of the area destroyed by HIFU compared to the volume of the pancreatic cancer on the imaging
Rate of secondary resectability From date of HIFU intervention to the date of last patient's last visit, assessed up to 60 months The secondary resectability will be calculated by the number of patients eligible for curative pancreatic resection following HIFU intervention compared to the total number of patients who received HIFU intervention
Clinical benefice rate regarding weight From the date of inclusion to the date of last patient's last visit, assessed up to 60 months. The clinical benefice rate regarding weight will be calculated by the number of patients showing an improvement in weight (in kilograms) from inclusion to the end of study, compared to the total number of patients who received HIFU intervention. A 10% or more increase of weight will be considered as a weight improvement.
Clinical benefice rate regarding performance status From the date of inclusion to the date of last patient's last visit, assessed up to 60 months. The clinical benefice rate regarding performance status will be calculated by the number of patients showing an improvement in performance status from inclusion to the end of study, compared to the total number of patients who received HIFU intervention. Performance status will be assessed by the Eastern Cooperative Group of Oncology (ECOG) score.
Progression-Free Survival (PFS) From date of inclusion until the date of first documented progression or date of death from any cause, whichever came first or until the date of the last update for patients without progression, assessed up to 60 months after inclusion The Progression-Free Survival (PFS) will be defined as the time from the date of HIFU intervention to the date of first documented disease progression or the date of death due to any cause or until the date of the last update for patients without progression
Local Progression-Free Survival (local PFS) From date of inclusion to the date of first disease progression or death or last update, assessed up to 60 months The local Progression-Free Survival (local PFS) will be defined as the time from the date of HIFU intervention to the date of first local progression
Rehospitalization rate during the first 30 days after HIFU intervention. From the date of HIFU intervention to 30 days after HIFU intervention The rehospitalization rate during the first 30 days after HIFU intervention will be calculated by the number of patients rehospitalized during the first 30 days after HIFU intervention compared to the total number of patients who received HIFU intervention
Incidence and severity of adverse events From the date of intervention to the date of last patient's last visit, assessed up to 60 months. Descriptive statistics will be used to describe the tolerance profile to HIFU intervention. The incidence and severity of adverse events (AEs), HIFU procedure-related AEs, Serious Adverse Events (SAEs), and deaths will be graded according to the latest version of the Common Terminology Criteria for Adverse Events (CTCAE) classification.
Quality of Life (QoL) From the date of inclusion to 6 months after HIFU intervention The patient's Quality of Life (QoL) will be assessed using the European Organisation for Research and Treatment of Cancer (EORTC) Quality Of Life Questionnaire C30 file. The questionnaire includes 30 questions whose scores will be calculated at each time point according to the scoring manuals of EORTC. Descriptive statistics will be used to evaluate baseline...
Overall Survival (OS) From date of inclusion to the date of death or date of last update, assessed up to 60 months The Overall Survival (OS) will be defined as the time from date of HIFU intervention to the date of death, from any cause. Patient not known to have died at the time of analysis will be censored based on the last recorded date on which the patient was known to be alive.
Length of hospitalization From date of HIFU intervention to the date of discharge from hospitalization, assessed up to 3 months The length of hospitalization will be calculated by number of days from the date of the HIFU intervention until the date of discharge from hospitalization
Clinical benefice rate regarding pain From the date of inclusion to the date of last patient's last visit, assessed up to 60 months. The clinical benefice rate regarding pain will be calculated by the number of patients showing an improvement in pain from inclusion to the end of study, compared to the total number of patients who received HIFU intervention. Pain will be assessed by an analog visual scale (0 to 10 scale, 0 being the best score and 10 the worse).
