Chemoimmunotherapy and Radiation in Pancreatic Cancer (CRIT)

January 31, 2018 updated by: Providence Health & Services

Phase I Trial of Chemoimmunotherapy and Hypofractionated Radiation Therapy for Borderline Resectable and Locally Advanced Pancreatic Adenocarcinoma.

The goal of this study is to evaluate the safety of combination treatment that includes chemotherapy, radiation therapy, and immunotherapy in patients with pancreatic cancer.

Study Overview

Detailed Description

This study is for borderline resectable and advanced pancreatic cancer patients. Patients will receive chemotherapy with gemcitabine and immunotherapy with daily tadalafil during the first 21 days of treatment. On study day 22, patients will receive the first of three planned doses of radiation therapy and continue daily tadalafil. Patients are then evaluated to determine if they are candidates for pancreaticoduodenectomy. Patients who are not candidates will continue daily tadalafil and receive gemcitabine chemotherapy. Patients who have surgery will resume daily tadalafil and gemcitabine chemotherapy following recovery from surgery. Patients will receive up to four cycles of gemcitabine.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Immunochemoradiotherapy
Immunotherapy with oral tadalafil daily; three doses of chemotherapy with IV Gemcitabine in 21-day cycles for up to 4 cycles; three fractions of external beam radiation to the pancreas and and regional lymph nodes; pancreaticoduodenectomy (surgical resection) for eligible patients.
One 2.5 mg tablet is self-administered orally by the study participant on a once daily basis.
Other Names:
  • Cialis
Three doses of gemcitabine (1000 mg / m^2)are given over a 21-day cycle. Patients may receive up to 4 cycles.
Other Names:
  • Gemzar
Patients will receive 3 doses of radiation (8-10 Gy per fraction).
Surgical resection.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Safety
Time Frame: 135 Days
Patients will return be seen in the clinic 8 times over the first 50 days for an evaluation of adverse events and toxicities before being evaluated for surgery. Patients who are not candidates for surgery will be seen in clinic 10 more times over the next 85 days for safety evaluations, and patients who have surgery will be seen 10 times over the 85 days following recovery from surgery for safety evaluations.
135 Days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Immune Infiltration in pancreaticoduodenectomy tissue
Time Frame: 50 Days
For surgery patients, formalin fixed and paraffin-embedded tumor tissue obtained during surgery will be sectioned and immunohistology performed to determine the tumor inflammatory micro-environment and the degree of macrophage and T cell inflammation.
50 Days
Quantification of T cells in peripheral blood pre- and post-treatment
Time Frame: 135 Days
Patients will provide a pre-treatment blood sample and 4 blood samples over 135 days to evaluate the influence of the study treatment on immune parameters. For patients who have surgery, the time period will be longer depending on their recovery time. Post-treatment long term follow up will occur every 12 weeks (+/- 2 weeks) beyond post-recovery date (PRD) 85 for 6 visits. Blood will be collected for immune monitoring at each visit.
135 Days
