About

This is a randomized controlled blinded superiority trial to evaluate the impact of perioperative immunosupplementation on immune function following resection for hepatopancreaticobiliary (HPB) malignancy.

Full description

This is a 1:1:1 randomized controlled blinded superiority trial to evaluate the impact of perioperative immunosupplementation on immune function following resection for hepatopancreaticobiliary (HPB) malignancy. Two variations of immunosupplementation will be compared to control nutritional supplement containing whey protein with an additional teaspoon (tsp) of placebo oil. These variations will be 1) a powdered formula containing whey protein and arginine (Active A) with an additional tsp of lipid bolus containing omega-3 fatty acids, and 2) a powdered formula containing whey protein and arginine (Active A) with an additional tsp of placebo oil which does not contain omega-3 fatty acids. The control nutritional supplement will be a powdered formula containing whey protein with an additional tsp of placebo oil.

Enrollment: 45 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients age 18 and over at time of diagnosis
• Resectable presumed liver, pancreas, or bile duct malignancy (i.e., liver metastases, HCC, cholangiocarcinoma, pancreatic or periampullary adenocarcinoma, NETs)as determined by surgeon in clinic
• Anticipated hospital stay at least three days post-surgery
• Ability to tolerate oral intake and comply with protocol requirements

Exclusion criteria

• Documented significant immunodeficiency due to underlying illness (e.g. HIV/AIDS) and/or medication (e.g. systemic corticosteroids, azathioprine, cyclosporin A). Subjects may be on physiologic doses of replacement prednisone or equivalent doses of corticosteroid (<7.5 mg daily)
• Subjects with resting hypotension (BP <90/50 at rest)
• History of autoimmune disease, such as but not restricted to, inflammatory bowel disease, systemic lupus erythematosus, ankylosing spondylitis, scleroderma, or multiple sclerosis
• Serious, active, intercurrent chronic or acute illness, or other active illness considered by the investigator as an unwarranted high risk for an investigational product
• Active infection of any site and/or active herpes requiring ongoing treatment
• Known pregnancy or nursing mothers
• Subjects with an allergy to the nutritional supplement or comparator including milk, fish and/or shellfish allergies
• Subjects with religious or other objections to consuming fish or shellfish
• Subjects with severe asthma defined as asthma not controlled with inhaled corticosteroids and additional controllers or by oral corticosteroid treatment (arginine can cause allergic response or make swelling in airways worse)
• Subjects with a known inherited guanidinoacetate methyltransferase deficiency (due to an inability to convert arginine to creatine)
• Subject with known current liver cirrhosis
• Subjects with documented myocardial infarction or life-threatening arrhythmia
• Subjects with known current cardiac failure or coronary artery disease causing unstable angina

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Quadruple Blind

---

45 participants in 3 patient groups, including a placebo group

Group A

Experimental group

Description:

Powdered formula containing whey protein and arginine (Active A) and lipid bolus containing omega 3 fatty acids. Participants will mix the powder (Active A) with 250 mL of water and drink the formula 3 times per day for 5 days. Each drink will be followed by consuming 1 tsp of the lipid bolus. This will be done for 5 days prior to the operation and for 5 days after the operation.

Treatment:

Dietary Supplement: Lipid bolus

Dietary Supplement: Active A

Group B

Active Comparator group

Description:

Powdered formula containing whey protein and arginine (Active A) and placebo oil. Participants will mix the powder (Active A) with 250 mL of water and drink the formula 3 times per day for 5 days. Each drink will be followed by consuming 1 tsp of the lipid bolus. This will be done for 5 days prior to the operation and for 5 days after the operation.

Treatment:

Dietary Supplement: Placebo oil

Dietary Supplement: Active A

Comparator

Placebo Comparator group

Description:

Powdered formula containing whey protein (Active B) and placebo oil. Participants will mix the powder (Active B) with 250 mL of water and drink the formula 3 times per day for 5 days. Each drink will be followed by consuming 1 tsp of the lipid bolus. This will be done for 5 days prior to the operation and for 5 days after the operation.

Treatment:

Dietary Supplement: Placebo oil

Dietary Supplement: Active B
