The Miami "EMPIRE" Trial - Eradication of Metastatic Pancreatic Cancer With Immuno-Radiation

Официальное название

A Phase 2 Single Arm Trial of Stereotactic Body Radiation Therapy Followed by Dual Immune Checkpoint Inhibition for Patients With Metastatic Pancreatic Ductal Adenocarcinoma - The Miami "EMPIRE" Trial - Eradication of Metastatic Pancreatic Cancer With Immuno-Radiation

Обзор

The purpose of this study is to assess if radiation therapy (which uses high-energy radiation to damage or destroy cancer cells) combined with immune checkpoint inhibitors (medications that helps the body recognize and attack cancer cells) will be beneficial for patients with metastatic pancreatic ductal adenocarcinoma.

Вмешательства

• Лучевая терапия Stereotactic Body Radiation Therapy
  The radiation therapy (RT) prescription biologically effective dose (BED10) goal for tumor (α/β=10) aims to achieve at least BED10= 60 Gy for a single fraction plan and at least BED10=100 Gy for a multi-fraction plan. This equates to a prescription dose of at least 20 Gy in a single fraction, 42 Gy over 3 fractions, 50 Gy over 5 fractions, and 62 Gy over 10 fractions. Radiation therapy must be completed for up to 10 daily treatments within a 15-day course.
• Препарат Botensilimab
  Participants will be receive 75mg of Botensilimab immunotherapy administered via intravenous infusion, every six weeks for up to 4 doses, about 24 weeks. Botensilimab therapy will begin no later than seven (7) days after completion of radiation therapy.
• Препарат Balstilimab
  Participants will receive 240mg of Balstilimab immunotherapy, administered via intravenous infusion, every 2 weeks for up to one (1) year. Balstilimab therapy will begin no later than seven (7) days after completion of radiation therapy.
