4 Blood Sample Overview All patients enrolled in the RE-ENERGIZE study will have blood samples taken unless they refuse consent. Blood samples will be used for DNA studies, lymphocyte function studies as well as inflammatory cytokines and heat shock proteins measurements. These studies will be designed to help understand how glutamine works, to measure the body s response to the study intervention and also to look at different markers in the blood of critical illness. Blood samples will be obtained on days 4, 7, 14 and 21 post start of the study intervention. We choose not to sample blood on day 1 because the analysis of our previous studies showed great variations in relation with fluid administration and water retention. The rationale for sampling at day 4 is based on the observation that the peak for inflammatory response occurs at that time. The 3 other samples are needed to assess the effects of glutamine on the time-course of inflammation, immunosuppression and the production of heat shock proteins. Since surgery has a significant and short lived impact on the parameters to be studied, the blood sampling will be made at least 12h post surgery. Therefore, the 4 sampling times will be identified as: acute phase (around day 4), day 7, 14 and 21 (post start of the study intervention). Blood Draw Visits Each RE-ENERGIZE patient enrolled is scheduled to have blood draws done on the following study days: Draw 1(4 days post start of study intervention) 48 hrs Draw 2 (7days post start of study intervention) 48 hrs Draw 3 (14 days post start of study intervention) 48 hrs Draw 4 (21 days post start of study intervention) 48 hrs Blood samples are to be drawn from the central line, wherever possible. If there is no central line, then blood should be drawn at the same time as routine blood work to prevent unnecessary blood draws. If there is no central line and there is no routine blood work scheduled for 4, 7, 14 or 21 days post start of study intervention (or the next day if weekend), do not draw blood. Blood samples must NOT be drawn within the period of 12 hrs after surgery or a blood transfusion. It is OK to draw blood before surgery/transfusion. If a blood draw visit day falls on a weekend, and it is not possible to obtain and process the samples on the weekend, the sample should be drawn on the closest working day. For example, blood draws due on Saturdays can be drawn on Fridays. Blood draws due on Sundays can be drawn on Mondays. November 12,

7 If you identify that tubes within your kits are expired, please contact Elizabeth Luzier to obtain replacement tubes. Elizabeth Luzier Wischmeyer Translational PharmacoNutrition Laboratory University of Colorado Denver Tel:(303) Cryovial/Tube Labels Each kit will contain enough labels for each cryovial/tube. The person processing the samples will need to add one label to each cryovial/tube that will be used for blood sampling. Each label includes an ID that corresponds to the day of blood draw and site number (4 digits). The last 3 digits refer to the patient enrollment number (or randomization number) and these are to be filled in by the person at the site drawing the blood. Example: For patient #1 from site # 1012, the ID# on the label would look like this: Site Number (4 digit) Draw 1 Draw 2 Draw 3 Draw _ _ _ _ Patient enrollment number (3 digits). To be filled in by site as follows: Enrollment # 1= 001 Enrollment # 2= 002, etc Blood draw # CERU assigned # for randomized patient (always will be 1) November 12,

8 Case Report Form (CRF) Labels In addition, ONE corresponding label for EACH day of blood draw will be provided for the Case Report Form. This label is to be attached to the Case Report Form titled Study Blood Work (page 25 of the Case Report Forms). Example: For patient #13 from site # 1012, for blood draw # 2 (7 days post start of study intervention), the Case Report Form label would look like this: Blood draw # Site Number (4 digit) Patient enrollment # Date blood drawn (DD/MMM/YYYY) Time blood drawn (hh:mm) The person processing the samples must add the enrollment number and the date and time of the blood draw to the CRF Label and attach it to the row for the appropriate Draw # on the Study Blood Draw Case Report Form (refer to instructions under Sample Log and Data Entry) Blood Draw Instructions Using an existing central line, draw blood in the following order: (1) 2 x Red/green speckled top tubes (2) 1 x Blue/black speckled top tube (3) 1 x Green top tube (4) 1 x PAXGENE tube (Hold vertically below patient s arm during collection)- 1 st draw only Invert all tubes 8-10 times. After tube inversion, place Green Top tube (sodium heparin) only on ice immediately and keep it on ice until further processing. NOTE: Prior to drawing blood, fill out and affix labels provided to blood draw tubes listed above. Ensure that you have a cup/container of ice with you when you draw the blood. November 12,
