Project Assistant: Roger Leung
Clinical Evaluation Research Unit
Protocol: Version April 11th 2012
Background & Objectives
• Point prevalence survey of nutrition practices in
ICU’s around the world conducted Jan. 27, 2007
• Enrolled 2772 patients from 158 ICU’s over 5
continents
• Included ventilated adult patients who remained in
ICU >72 hours
What study patients actually received?
• Average Calories in all groups:
– 1034 kcals and 47 gm of protein
Result:
• Average caloric deficit in Lean Pts:
– 7500kcal/10days
• Average caloric deficit in Severely Obese:
– 12000kcal/10days

ICU patients are not all created equal…should
we expect the impact of nutrition therapy to be
the same across all patients?
TOP UP Trial: Hypothesis
Increased early energy and protein
delivery with PN+EN to underweight
(BMI < 25) and obese (BMI ≥ 35) critically
ill patients will result in improved
survival at 60 day versus standard EN
alone
Objectives
• Perform an initial multi-center pilot study in
Canada,USA, France & Belgium in 160 patients to
demonstrate feasibility
• Assuming feasibility, large-scale 2000 patient multicenter, multinational trial will be undertaken

Objectives: Pilot Study
Primary Aim:
• Difference in the calories and protein received between the control and
intervention groups
• Estimate recruitment rate
• Evaluate the safety, tolerance, and logistics around providing
supplemental PN in the study population, e.g.
• To ensure adequate glycemic control in both groups
• To ensure other metabolic consequences of the feeding strategies
are minimized
• To establish adequate compliance with study protocols and
completion of case report forms.
Secondary Aims:
• Explore the effect of differential intake of protein/energy on muscle mass
and muscle function.

SAE Identification and Reporting
Imp Manual p XX-XX
SAE Identification
A serious adverse event is any untoward medical occurrence that at any
dose,
 Results in death
 Is life threatening (the subject was at immediate risk of death from the event
 Results in persistent or significant disability/incapacity
 Requires in patient hospitalization possibly related to the use of the study
materials
 Prolongs of hospitalization.
 Is a congenital anomaly or birth defect
 Is an important medical event that may jeopardize the patient and may
require medical or surgical intervention to prevent one of the outcomes listed
above medically important condition
An unexpected adverse event is that event that is NOT expected due to
the progression of the underlying disease or co-morbid illnesses.
Adverse Event must be serious and unexpected to be reported

Dosing Procedures
(both groups)
Dosing of the intervention will depend upon the energy and
protein needs of the patient
To be determined by the dietitian/MD
Protocol, Imp Manual p X
Protein and Calorie needs
Guidelines for Dosing of Protein and Energy Based on BMI
Upon enrolment, the dietitian/MD will:
1.
Calculate prescribed energy and protein intake as per standard practice
2.
Ensure that minimum energy and protein needs are met as follows
Minimum Energy
Minimum Protein
BMI<25
25 kcals/kg actual wt
1.2 g/kg actual wt
BMI ≥ 35
20 kcals/kg ABW*
1.2 g/kg ObesityABW*
*Obesity-adjusted Body weight= IBW + [actual weight – IBW] x 0.25,
where IBW is ideal body weight (BMI of 25)
Imp Manual p X
Prescribed Volume
3. Determine the prescribed volume for EN (or study PN, or EN + study
PN) in mls/24 hrs to meet the prescribed energy and protein needs
MUST use enteral formula of 1.2  0.2 kcal/ml
Meet protein needs over energy needs
4. Determine the hourly rate of EN (or study PN, or EN + study PN)
(assume PN = 1 Kcal/ml)
Must be done
asap after
randomization

dietitian/MD

Initiate PN study solution at 25 ml/hr (or faster) and advance by 25 ml q
4 hrs to target rate as tolerated

Monitor blood sugars and electrolytes every 4 hrs as needed

Do not advance PN/EN if BS, K, Phosp, Mag becoming more
abnormal (ranges as per your local site)

Dispensing & Storage
Pharmacy
For most sites, the pharmacy may only be involved in the initial
receipt of the Olimel.
The Research Coordinator/delegate will therefore be responsible
for the following:
 storage of Olimel
 dispensing of Olimel (including addition of labels)
 completion of dispensing and accountability logs
 sending temp logs to CERU monthly
 maintenance of inventory and destruction of the
expired/unused product
Imp Manual p X
Olimel N9E
Will be supplied to all sites before enrollment starts
At time of delivery, if pre-activation occurs (solution has turned milky) do not
use and report to CERU Project Leader
Unmixed product: store between 15 to 30 degrees C. Do not freeze.
Dedicated Central line needed,
piggybacking with other lines not recommended
unless standard practice for PN at your site
CRS/REDCAP Manual p 12
Central Randomization System
Upon randomization, Research Coordinator will be notified of the study group
the patient has been randomized to
EN only or
EN + Supplemental PN
Imp Manual p X
Supplemental PN
For day 1:
Research Coordinator to obtain hourly rate of infusion
from dietitian/MD
Prepare enough 1 litre bags of the
investigational product to last one day
Example: Dietitian/MD has determined that the hourly rate is 65
ml/hr:
the total volume needed for 1 day would be 65 X 24 = 1536 mls.
The pharmacist /delegate is to prepare 2 X 1 Litre bags of the
product.
In order to prevent running out of product before the bag
change time, you may need to send 2 X 1 litre bags on day 1
Supplemental PN
For Subsequent days:
The Research Coordinator to determine how much enteral
nutrition the patient is anticipated to tolerate and will prepare
enough Olimel accordingly.
Example:
1. Goal rate = 65 ml/hr
2. Patient tolerating 25 ml/hr well today (or expected to)
3. Prepare enough product for remaining volume = 40 ml/hr X 24
= 960 mls = 1 X 1 litre bag

Olimel in overpouch
After removing pouch, check the Oxygen indicator
Black
Light yellow
brown
After overwrap has been removed, Olimel can be stored for 24 hours under
refrigeration followed by 24 hours administration
Check non permanent seals
Confirm the integrity of the bag and of the non-permanent
seals
Use only if the bag is
 not damaged, if the non-permanent seals are intact (i.e. no mixture of
the contents of the three compartments)
 if the amino acids solution and the glucose solution are clear, colourless
practically free of visible particles, and
 if the lipid emulsion is a homogeneous liquid with a milky appearance
1. Ensure that the product is at room temperature when breaking the non- permanent seals
2. After removing overpouch, manually roll bag from hanger side down
Continue rolling the bag until all non permanent seals are broken ½ way
Solution turns milky showing that the seals are broken (1/2 way)
Mix well by inverting the bag 3 times
1. Solution will turn to a milky color & is ready to hang
2. Use immediately after reconstitution
