A Randomized Trial of Supplemental Parenteral Nutrition in Under and Over Weight Critically Ill Patients : The TOP UP

1. T P UP A Randomized Trial of Supplemental Parenteral Nutrition in Under and Over Weight Critically Ill Patients: The TOP UP Trial October 17th 2011 Study Sponsor: Dr. Daren Heyland Project Leader: Rupinder Dhaliwal Project Assistant: Roger Leung Clinical Evaluation Research Unit

2. Protocol: Version March 28th 2011

3. Background & Objectives

4. 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

5. 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

7. ICU patients are not all created equal…should we expect the impact of nutrition therapy to be the same across all patients?

8. 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

9. 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 multi-center, multinational trial will be undertaken

10. Study Design Randomized Trial (unblinded) EN only Primary Outcome Stratified by: Site BMI Med vs Surg On EN ICU patients R BMI <25 60-day mortality BMI >35 Fed enterally EN plus supplemental PN for 7 days

11. 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.

12. Outcomes:Pilot study Primary outcome: 60 day mortality Secondary outcomes: • ICU (28 day) mortality • Hospital mortality • Duration of mechanical ventilation • Duration of stay (ICU and hospital) • Development of ICU-acquired infections • Multiple organ dysfunction (SOFA and PODS) • Functional status, HR QOL at 3 & 6 months • Muscle Function Tests

17. Delegation of Authority Logs “The Investigator should maintain a list of appropriately qualified persons to whom the investigator has delegated significant trial-related duties (ICH section 4.1.5)” Completed Log to be sent to CERU before start of trial Imp Manual p 11,12

18. Inclusion Criteria Imp Manual p 13, CRFs If using estimated weight/height, you may add a buffer of  1 for BMI after rounding 1) Mechanically ventilated adult patients (≥18 years old) 2) Expected to remain mechanically ventilated for more than 72 hours 3) On enteral nutrition or expected to initiate enteral nutrition within 48 hours from ICU admission Interpret “48 hrs” as “7 days” due to exclusion criteria # 4 4) BMI < 25 or >35 based on pre-ICU actual or estimated dry weight

19. Exclusion Criteria Imp Manual p 14, CRFs >48 hours from admission to ICU to time of consent (any ICU) Not expected to survive an additional 48 hours from screening evaluation 3. Lack of commitment to full, aggressive care (anticipated withholding or withdrawing treatments in the first week but isolated DNR acceptable)

20. Exclusion Criteria Imp Manual p 14, CRFs Inclusion criteria #3 means this will never be captured What about patients that have not been challenged with EN? 4. Patients with an absolute contraindication to EN deemed to require PN for the first 7 days of ICU admission (e.g. GI obstruction or no GI tract access for any reason) 5. Already at goal rate of Enteral Nutrition at screening evaluation (at ≥ 60% target rate and no evidence of intolerance i.e. high GRVs)

21. To enrol the right type of patient AS A GUIDELINE if patient has not been challenged with EN… • is NOT at risk for EN intolerance  • is at risk for EN intolerance Refer to list of risk factors for GI intolerance

22. Imp Manual p 15 Risk Factors for EN Intolerance • High APACHE Scores (>25) • On more than 1 pressor, or increasing doses of pressors • Receiving continuous infusion of narcotics • High NG/OG output (> 500 mls over 24 hrs) • Recent surgery involving esophagus, stomach or small bowel OR peritoneal contamination with bowel contents • Pancreatitis • Multiple GI investigations • Recent history of diarrhea/ C.difficile • Surgical patients with future OR’s planned • Abdominal Aortic Aneurysm (emergency vascular surgery)

25. Eligibility confirmation Document in the medical chart or Sign worksheet by MD and keep as source Prompted at time of Pre randomization Refer to Consent Training Slides

26. Infection AdjudicationSite Investigator to make determination of a newly acquired infection based on antibiotic and microbiology data

27. Infection Adjudication CRS/REDCAP manual p 21-27

28. Suspicion of ICU Infection: Antibiotics Is this antibiotic prescribed for prophylaxis? Is this a substitute for an antibiotic previously ordered for an infection that occurred within 72 hrs of admission to ICU? CRFs p 40, 41 NO to both YES to either Clinical Suspicion of Infection Need adjudication by Site Investigator/MD Delegate No adjudication needed

29. Suspicion of ICU Infection: Microbiology Is this organism a manifestation of an infection that occurred within the first 72 hrs of admission? CRFs p 42, 43 NO YES Clinical Suspicion of Infection Need adjudication by Site Investigator/MD Delegate Indicate if: Relapse/Recurrent OR Persistent infection No adjudication needed

30. CRS/REDCAP Manual p 24 Infection Adjudication: REDCAP • This is a newly acquired infection • This is NOT a newly acquired infection • This is a previously adjudicated infection

31. Infection Adjudication Site Investigator will need: • Access to view the Infection Adjudication table on REDCAP (Research Coordinator to show this) • Appendix 9 Categories of Infection • Appendix 10 Definitions of No Newly Acquired Infection • Medical Chart Refer to CRS/REDCAP Manual pages 21-27 for step by step process

32. SAE Identification and Reporting

33. SAE Identification Imp Manual p 38-49 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 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

34. Imp Manual p 40 SAE Reporting (to CERU) Must be done on electronic data capture system and faxed to CERU

35. Imp Manual p 42-44

40. Investigator Confirmation CRS/REDCAP Manual p 30

41. Imp Manual p 17 Study Groups

42. 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

43. Protein and Calorie needs Protocol, Imp Manual p 25 Guidelines for Dosing of Protein and Energy Based on BMI • Upon enrolment, the dietitian/MD will: • Calculate prescribed energy and protein intake as per standard practice • 2. Ensure that minimum energy and protein needs are met as follows *Obesity-adjusted Body weight= IBW + [actual weight – IBW] x 0.25, where IBW is ideal body weight (BMI of 25)

44. Imp Manual p 25 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

45. Study Tools

46. Other considerations…Propofol Propofol calories to be factored into assessment of caloric needs, only as per discretion of dietitian/MD

47. Imp Manual p 17 Enteral Nutrition (both groups) • Enteral Nutrition to start as per usual practice (patient stabilized, NG/Feeding tube in place) • Standard enteral nutrition formula 1.0 to 1.4 kcals/ml • (hypercaloric formulas not allowed) • NO protein supplements (for 7 days) • NO probiotics (for 7 days) • NO glutamine supplements (for 7 days) • Start at 25 ml/hr and increase every 4 hrs as tolerated until goal rate • Discontinue when the feeding tube comes out Refer to Enteral Nutrition Algorithm & Paired Feeding Algorithm appendices C & F

48. Imp Manual p 18 Trace Elements and Multivitamins • DO NOT add to the PN solution • If patient does not receive EN and is dependant on PN for >48 hrs, IV supplementation is recommended Suggested guidelines • Standard doses of multivitamins • 5 mg zinc • 1 mg copper • 0.5 mg manganese • 10 mg chromium • 60mcg selenium. • use commercially available trace element solutions doses can be adjusted at discretion of the medical team

49. Dietitian Determine Energy/protein needs (prescribed Volume) Follow Canadian Clinical Practice Guidelines Assist with data collection Baseline Nutrition Assessment Daily EN monitoring Daily PN monitoring (non study PN)
