Study of Immune Checkpoint Inhibition With Radiation Therapy in Unresectable, Non-metastatic Pancreatic Cancer
Pancreatic Cancer
About this trial
This is an interventional treatment trial for Pancreatic Cancer focused on measuring Unresectable, Locally Advanced, Non-Metastatic
Eligibility Criteria
Inclusion:
- Histopathological confirmation of pancreatic adenocarcinoma prior to study entry.
- Unresectable and non-metastatic disease
- At least 1 measurable metastatic lesion by RECIST 1.1, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >20 mm with conventional techniques, or as >10 mm with spiral computed tomography (CT) scan, and that is accessible for biopsy.
- Age >18 years
- ECOG performance status 0-1
- Normal organ and marrow function as defined below:
Absolute Neutrophil Count > 1,000/mcL Platelets ≥ 75,000/mcL Total Bilirubin ≤ 2 x ULN Serum Albumin ≥ 2.5 g/dl ALT or AST up to 3 x ULN if no liver metastases or ALT or AST up to 5 x ULN if liver metastases present Creatinine < 2 x institution upper limit of normal OR Creatinine Clearance > 45 mL/min/1.73 m2, as calculated below, for patients with creatinine levels above institutional normal
- No history of another malignancy in the past 5 years, except for treated non-melanoma skin cancer, superficial bladder cancer, or carcinoma-in-situ of the cervix
- No coexisting medical problems that would limit compliance with the study
- Ability to understand and sign a written informed consent document. Patient must have willingness and ability to comply with scheduled visits, treatment plans, laboratory tests and other study procedures.
- Female subjects of childbearing potential must have a negative serum pregnancy test prior to study entry
- Female subjects of childbearing potential and males must agree to use a highly effective method of contraception for the duration of study treatment, and for six months after discontinuation of the study drug.
Exclusion:
- Resectable, borderline resectable or metastatic disease
- Prior chemotherapy, targeted therapy, immunotherapy, clinical trials or radiotherapy for pancreatic cancer.
- Active or history of concomitant therapy with any of the following: interleukin (IL) 2, interferon, or other non-study immunotherapy regimens, immunosuppressive agents, other investigational therapies, or chronic use of systemic corticosteroids (inhaled and topical steroids are permitted)
- Active or history of chronic autoimmune disease with symptomatic disease within the 3 years before randomization.
- Active or history of inflammatory bowel disease (colitis, Crohn's disease), irritable bowel disease, celiac disease, or other serious, chronic, gastrointestinal conditions associated with diarrhea.
- Diverticulitis within the past 2 years.
- Active HIV infection
- Uncontrolled systemic disease including, but not limited to, ongoing or active systemic infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- Brain metastases
- Patients should not be vaccinated with live attenuated vaccines within 1 month of starting tremelimumab and MEDI4736 treatment.
- History of hypersensitivity reaction to human or mouse antibody products
- Evidence of pre-existing idiopathic pulmonary fibrosis on CT scan at baseline
- Unhealed surgical wound at time of treatment, or history of unhealed surgical wound for more than 30 days
- History of an invasive secondary primary malignancy diagnosed within the previous 3 years, except for appropriately treated stage I endometrial or cervical carcinoma, prostate carcinoma treated surgically or non-melanoma skin cancer.
- Non-protocol antineoplastic agents will not be permitted during this study
- Patients may not recieve other investigational agents.
- Pregnant or lactating women
- Subjects with dementia or significantly altered mental status that would prohibit understanding or rendering of information and consent and compliance with the requirements of the protocol.
- Subjects unable or unwilling to abide by the study protocol or cooperate fully.
