Code:

NCT04990609

Conditions

Pancreatic Ductal Adenocarcinoma (PDAC)

Eligibility Criteria

Sex: All

Healthy Volunteers: Not accepted

Interventions

Endoscopic Ultrasound (EUS)-Guided Radiofrequency Ablation (RFA)

Neoadjuvant Chemotherapy (NAC)

Study Details

Brief summary:

The objectives of this study are to determine the feasibility, tolerability, and treatment effect of endoscopic ultrasound (EUS) radiofrequency ablation (RFA) plus standard-of-care neoadjuvant chemotherapy (NAC) in the treatment of pancreatic ductal adenocarcinoma (PDAC). Endoscopic ultrasound (EUS) radiofrequency ablation (RFA) and neoadjuvant chemotherapy (NAC) will be performed before tumor resection surgery, with the goal of shrinking a tumor or stopping the spread of cancer so that surgery might be less invasive and more effective.

Interventions and Outcome Measures

Arms

experimental: Neoadjuvant chemotherapy (NAC) plus endoscopic ultrasound (EUS) radiofrequency ablation (RFA)

Interventions

Endoscopic Ultrasound (EUS)-Guided Radiofrequency Ablation (RFA)

Endoscopic ultrasound (EUS)-guided radiofrequency ablation (RFA) consists of the application of an alternating current with a frequency of 350-500 kilohertz (kHz) to the target tissue via a special electrode located at the tip of an echoendoscope. The alternating current causes the vibratory movement of ionic particles in the abutting and adjoining tissue and results in the generation of heat. However, RFA induces not only local disruption of the tumor by heat, but it also produces localized coagulation necrosis of the tumor; which induces the release of large amounts of cellular debris. This cellular debris represents a source of tumor antigens that can trigger a host adaptive immune response against the tumor.

Neoadjuvant Chemotherapy (NAC)

The NAC regimen will be determined clinically by the participant's physician \[possible regimens are either mFOLFIRINOX or Gemcitabine Nab-Paclitaxel +/- Cisplatin (GemAbraxane)\].

Primary outcome measure

  • Number of participants who are able to complete neoadjuvant chemotherapy plus EUS-RFA and later undergo surgical tumor resection [ Time Frame: From the time of EUS-RFA NAC intervention to the time of surgical tumor resection (about 5-6 months) ]
