Could a new PET scan help match pancreatic cancer patients to the right therapy?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult patients 18 years of age or older with: * newly diagnosed early-staged localized pancreatic ductal adenocarcinoma (PDAC) scheduled to undergo Whipple procedure (cohort 1a) or down-staged after neoadjuvant chemotherapy now eligible to undergo resection OR * borderline resectable, locally advanced, metastatic, or recurrent PDAC (cohort 1b) scheduled to undergo chemotherapy OR * borderline resectable, locally advanced PDAC (cohort 2) who is eligible and / or signed consent to undergo CCR2-targeted therapy example:\[(phase 1/2 clinical trial combining an oral CCR2/5i (BMS-813160) with chemotherapy (gemcitabine plus nab-paclitaxel) and anti-PD-1 (nivolumab), PI, Dr. Kian Lim) HRPO #201806007 - closed to accrual March 2022\] AND * at least one measurable \[defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 10 mm with CT scan or MRI\] A cohort 1B subject who has been previously treated for PDAC with a diagnosis of recurrence and a lesion size of 1.5 cm or greater will be allowed to enroll before institution of therapy or within 20 days after starting a 2nd line or later (new therapy) for recurrent disease. * Able to give informed consent * Not currently pregnant or nursing: Subject must be surgically sterile (has had a documented bilateral oophorectomy and/or documented hysterectomy), post-menopausal (cessation of menses for more than 1 year), non-lactating, or of childbearing potential for whom a urine pregnancy test (with the test performed within the 24 hour period immediately prior to administration of 64Cu-DOTA-ECL1i) is negative Exclusion Criteria: * Patients with other invasive malignancies, with the exception of non-melanoma skin cancer, who had (or have) any evidence of the other cancer present within the last 5 years * Unable to tolerate up to 90 min of PET/CT imaging per imaging session.
