Clinical Trial Summary

This research protocol will evaluate the feasibility of administering neoadjuvant gemcitabine and nab-paclitaxel with hypofractionated, image guided, intensity modulated radiotherapy (HIGRT) in resectable and borderline resectable pancreatic cancer

Description:

Pancreatic cancer is the fourth leading cause of cancer-related death in the United States and accounts for roughly 40,000 deaths each year. Despite the use of neoadjuvant and adjuvant therapies, little progress has been made in the the last three decades, and the search for more efficacious treatment continues.In patients with a good performance status the combination of effective systemic therapy with gemcitabine/nab-paclitaxel and high dose local radiotherapy may improve disease outcomes. This is a prospective, single arm study in patients in newly diagnosed, previously untreated pancreatic cancer who are planned to undergo surgical resection The primary objective of this study is to evaluate the toxicity of a neoadjuvant approach incorporating gemcitabine/nab-paclitaxel and Hypofractionated image guided intensity-modulated radiotherapy (HIGRT) prior to surgical resection. Eligible subjects will recieve standard neoadjuvant gemcitabine and nab-paclitaxel dosing is as follows:Nab-Paclitaxel (125mg/m2) days 1,8,15 every 28 days for 2 cycles Gemcitabine (1000mg/m2) days 1,8,15 every 28 days for 2 cycles followed by HIGRT and surgical resection.

Adjuvant chemotherapy may be given post surgery at the discretion of the treating medical oncologist.

Eligibility

Inclusion Criteria:

1. Patient has signed informed consent and is willing to comply with the protocol

2. Histologically or cytologically proven adenocarcinoma of the pancreas (within the last 90 days)

Negative pregnancy test in female patients of child-bearing potential per institutional policy. Post-menopausal women must have had amenorrhea for at least 18 months to be considered non-child bearing

Clinically significant atherosclerotic cardiovascular disease including patients with New York Heart Class II/III/IV CHF, ventricular arrhythmias requiring medication, myocardial infarction, cerebrovascular accident, transient ischemic attack, coronary artery bypass grafting, angioplasty, cardiac or other vascular stenting within the past 6 months

10. History of abdominal fistula, gastrointestinal perforation, intra-abdominal abscess within six months prior to treatment start

11. History of collagen vascular disease or inflammatory bowel disease (Crohn's or ulcerative colitis)

12. Current grade 2 or higher peripheral neuropathy

13. Anticoagulation with warfarin

Intervention

Drug:
• Gemcitabine/nab-Paclitaxel
Prospective, single arm study ; eligible subjects will recieve 2 cycles of neoadjuvant Gemcitabine/nab-Paclitaxel. All chemotherapy administered to study subjects is standard of care. The chemotherapy combination, gemcitabine/nab-paclitaxel, is considered to be a standard-of-care, non-investigational chemotherapy combination; chemotherapy dosing and treatment schedule will be managed by the treating medical oncologist. Restaging will be completed post chemotherapy.

Radiation:
• Radiation therapy
5 fractions of hypofractionated IGRT or IMRT at 5Gy per fraction will be delivered before surgery. Restaging will be completed post radiation therapy.

Other:
• Sugical resection
Surgical resection of the pancreas post radiation therapy

Drug:
• Adjuvant chemotheapy
Adjuvant chemotherapy may be given after surgery at the clinical discretion of the medical oncologist

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Feasibility as Measured by Number of Participants Who Complete the Neoadjuvant Gemcitabine/Nab-paclitaxel and HIGRT Regimen	The neoadjuvant regimen will be considered feasible if (a) the trial can accrue 25 patients in no more than 3 years and (b) if at least 17 of the 25 patients adhere to the neoadjuvant regimen and c) the acute grade 3+ non-hematologic acute toxicity is less than 50% (exclusing fatigue and alopecia).	approximately 6 months
Secondary	Number of Participants Experiencing Grade >/=2 Acute Toxicity	CTCAE version 4 will be used for all toxicity assessments. The acute toxicity rate, defined as any non-hematologic grade 2+ toxicity occurring during HIGRT treatment through 60 days post-treatment, will be estimated with its exact 80% confidence interval. Likewise, we will determine the rate of grade 2+ hematologic toxicity occurring during treatment through 60 days post treatment and the proportion of patients requiring treatment breaks longer than 5 days.	60 days post surgery
Secondary	Number of Participants Who Underwent Surgical Resection	Patients who undergo surgical resection will be documented	14-30 days post surgery
Secondary	Number of Participants Who Received an R0 Resection	Pathologic review will determine if an R0 resection has been performed. R0 resection indicates a microscopically margin-negative resection, in which no gross or microscopic tumor remains in the primary tumor bed.	14-30 days post surgery
