Clinical Trial Summary

In this clinical trial, if the doctor knows or suspects that a growth in the pancreas is cancer (adenocarcinoma), then a sample of the growth is tested (the test is called molecular profiling). The results of the test are used by the doctor to recommend therapy (chemotherapy and radiation therapy) that the patient will receive before having surgery to remove the adenocarcinoma. When the patient goes to surgery, the adenocarcinoma that is removed is tested again. The results of that test are used to guide the choice of therapy after surgery.

The chemotherapy drugs and the radiation therapy used in this clinical trial are already approved for treatment of pancreas cancer. This trial is intended to establish which treatment is best for a specific patient, based on test results from that patient's actual adenocarcinoma. In the past, the decision as to which treatment the patient will receive was not based on testing of the actual adenocarcinoma.

Hypothesis: Resectability rate, overall survival rate and progression-free survival in subjects with adenocarcinoma of the pancreas will be superior for who receive targeted "personalized" therapy.

Intervention

Drug:
• Milestone 1: Targeted chemotherapy prior to surgery
The molecular profile from the biopsy before surgery will point to a particular chemotherapy treatment.

Radiation:
• Milestone 2: Chemoradiotherapy (cXRT)
A radio-sensitizing chemotherapy agent (either Gemcitabine or Capecitabine) will be given. Using 3D conformal or intensity-modulated radiation therapy (IMRT) techniques, patients will receive a total dose of 50.4 Gy prescribed to the 95% isodose at 1.8 Gy/fraction (28 fractions).

Drug:
• Milestone 3: Targeted chemotherapy prior to surgery
The molecular profile from the biopsy before surgery will point to a particular chemotherapy treatment.

Radiation:
• Milestone 3: Chemoradiotherapy (cXRT)
A radio-sensitizing chemotherapy agent (either Gemcitabine or Capecitabine) will be given. Using 3D conformal or IMRT techniques, patients will receive a total dose of 50.4 Gy prescribed to the 95% isodose at 1.8 Gy/fraction (28 fractions).

Drug:
• Milestone 4: standard FOLFIRINOX chemotherapy prior to surgery
A biopsy of the borderline tumor does not provide a molecular profile that can be used to target treatment. The treatment will be standard FOLFIRINOX chemotherapy regimen.

Radiation:
• Milestone 4: Chemoradiotherapy (cXRT)
A radio-sensitizing chemotherapy agent (either Gemcitabine or Capecitabine) will be given. Using 3D conformal or IMRT techniques, patients will receive a total dose of 50.4 Gy prescribed to the 95% isodose at 1.8 Gy/fraction (28 fractions).

Drug:
• Milestone 5: Targeted chemotherapy after surgery
The molecular profile from the surgical specimen will point to a particular chemotherapy treatment.

Radiation:
• Milestone 5: Chemoradiotherapy (cXRT)

Drug:
• Milestone 6: Gemcitabine after surgery

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Subjects Completing Therapy Including Surgical Resection.	This outcome measure is the number of subjects completing therapy up to and including surgical resection. In this context, surgical excision of residual tumor is an option in the progression of usual care. Surgery was contraindicated for some participants. This measure is the number of subject who were eligible for and completed the surgical procedure.	At time of surgery (approximately 10 to 20 weeks after screening)
Secondary	Overall Survival in Months	This measure is the median time of survival (in months) at five years from the initiation of therapy. Results will be presented for two cohorts: subjects completing neoadjuvant therapy and surgical resection; and subjects completing neoadjuvant therapy but without surgical resection.	5 years
Secondary	Progression-free Survival	This measure is the number of subjects not experiencing tumor progression at five years from initiating therapy.	5 years
Secondary	Use of Biomarkers to Determine Course of Treatment	The number of subjects for whom a biomarker (i.e., molecular profile) was used to determine the course of treatment.	Initiation of therapy (approximately 4 to 12 weeks after screening) until surgery (approximately 10 to 20 weeks after screening)
Secondary	Histologic Response to Targeted Chemotherapeutic Regimens in Resected Tumors.	The number of tumors showing a histologic response. Histological response will be measured using the Ryan Score method as defined by the American Joint Committee on Cancer, 7th edition (see Edge, 2010). Grading categories are defined as: Grade 0 (complete response); Grade 1 (near complete response); Grade 2 (partial response); and Grade 3 (poor or no response).	At time of surgery (approximately 10 to 20 weeks after screening)
