Study Overview

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

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.

Allocation:
Na

Interventional Model:
Single Group

Masking:
None

Arms and Interventions

Participant Group/ArmIntervention/Treatment
EXPERIMENTAL: Radiation, Botensilimab Combined with Balstilimab Treatment Group

Participants in this group will receive Stereotactic Body Radiation Therapy (SBRT), followed by Botensilimab immunotherapy (ImT) for up to 24 weeks, in combination with Balstilimab ImT for up to one year. Total participation duration is up to five years.

RADIATION: 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 o

DRUG: 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.

DRUG: 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.
Primary Outcome MeasuresMeasure DescriptionTime Frame
Clinical Benefit Rate (CBR)The Clinical Benefit Rate (CBR) among participants will be reported. CBR is the number of participants achieving complete response (CR), partial response (PR) or stable disease after start of study therapy. Response will be assessed using Immune-related Response Evaluation Criteria in Solid Tumors (iRECIST) 1.1 criteria.Up to 15 months
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Objective Response Rate (ORR)Objective response rate will be reported, based on best response according to Immune-related Response Evaluation Criteria in Solid Tumors (iRECIST) 1.1 criteria. Objective response (OR) is defined as the number of participants with confirmed complete response (CR) or confirmed partial response (PR) to study therapy.Up to 15 months
Progression-Free Survival (PFS)Progression-free survival (PFS) among participants will be reported. PFS is defined as the elapsed time in months since the start of radiation therapy until the first documentation of disease progression or death.Up to 5 years
Overall Survival (OS)Overall survival (OS) among participants will be reported. OS is defined as the elapsed time in months from the start of radiation therapy until death by any cause.Up to 5 years
Number of Participants Experiencing Grade 3 or Higher ToxicitiesThe number of participants experiencing Grade 3 or higher toxicities will be reported using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.Up to 15 months
