Official title

Endoscopic Ultrasound-guided Intratumoral Iodine125-Seeds Implantation Combined With Gem/Nab-P Chemotherapy Versus Gem/Nab-P Alone for Metastatic Pancreatic Carcinoma: a Randomized, Controlled, Trial

Overview

The goal of this clinical trial is to evaluate the clinical efficacy and safety of endoscopic ultrasonography (EUS)-guided radioactive iodine 125 seeds in combination with AG regimen chemotherapy for the treatment of metastatic pancreatic cancer. The main questions it aims to answer are: * whether the combination of minimally invasive endoscopy-guided local radiation therapy with chemotherapy may improve overall survival * the adverse events of the combination therapy Participants will receive the implantation of radioactive seeds under EUS guide. 48h after implantation, chemotherapy with Gem/nab-P given on days 1 and 8 of each 21-day cycle will be conducted. Researchers will compare the I125+AG group with the group that takes AG chemotherapy alone to see if the overall survival can be improved.

Interventions

  • Procedure Iodine125-Seeds implantation
    Endoscopic ultrasound-guided intratumoral iodine125-Seeds implantation
  • Drug Gem/nab-P Chemotherapy
    nab-paclitaxel (125 mg per square meter of body-surface area) followed by gemcitabine (1000 mg per square meter) on days 1, 8 every 3 weeks

Primary outcome measures

  • Overall survival (OS) [Time frame: 48 months]
Secondary outcome measures (6)
  • Incidence and severity of Adverse events (AEs) [Time frame: 48 months]
  • Progression-free survival (PFS) [Time frame: 48 months]
  • Overall Response Rate (ORR) [Time frame: 48 months]
  • CA19-9 response [Time frame: 48 months]
  • Metabolic response [Time frame: from baseline to the end of 2nd chemotherapy cycle]
  • Visual analog scale (VAS) [Time frame: 48 months]
