CONFIDENTIAL Brentuximab vedotin (ADCETRIS™) Shipment & Receipt (cont.) Upon receipt of the drug shipment, please take the following IMMEDIATE action: –Step 1. Remove the TagAlert monitor from the package and store study drug in the appropriate temperature controlled environment. Please be aware this monitor does not need to be stopped –Step 2: If the LCD is displaying the “OK” icon, no alarms have been triggered during the trip –Step 3: If the LCD is displaying black squares over the “OK” and the numbers 1, 2, 3 and/or 4, then an alarm has been triggered.

Refer to Bracket – Millennium C25003 Site User Instruction Manual to receive shipment in IXRS –IXRS will not dispense drug unless this acknowledgement step has been conducted –IXRS will ask for confirmation if: shipment included a temperature monitoring device any study drug was damaged shipment was received within temperature range –ICON CRA or study management should be contacted if damage or a temperature excursion is detected during the receipt process 77

CONFIDENTIAL 88 Brentuximab vedotin (ADCETRIS™) Storage and Handling Storage –ADCETRIS™ vials/cartons must be stored refrigerated at 2–8°C in an appropriate locked room accessible only to the pharmacist, the investigator, or a duly designated person –Refrigerator temperature logs must be maintained Report storage temperature excursions immediately to CRA Temperature excursions evaluated by Millennium on an individual basis –Recommend protecting all vials and solutions from direct sunlight until the time of use Handling –ADCETRIS™ does not contain preservatives Opened vials and reconstituted solution must be used within 24 hours Reconstituted solution must not be stored at room temperature –Reconstituted solution and infusion bags must not be shaken

CONFIDENTIAL Brentuximab vedotin (ADCETRIS™) Dose Calculation Initial dose of brentuximab vedotin is based on the Day 1 weight Patients must be weighed at each dosing visit –The dose must be adjusted if the weight has increased or decreased by at least 10% from Day 1 –When there is a 10% weight change, continue to use the new dose until the weight changes (+/-) by an additional 10% Dose calculation should be rounded to the nearest whole number of milligrams. 99

CONFIDENTIAL Brentuximab vedotin (ADCETRIS™) Reconstitution Dose preparation steps: 1.Remove the plastic flip-off caps from the necessary number of vials of brentuximab vedotin 2.Reconstitute lyophilized brentuximab vedotin by adding 10.5 mL Sterile Water for Injection, USP to the vial, directing the stream at the side of the vial 3.GENTLY swirl the vial until the contents are completely dissolved. Slight “bubbling” of the solution upon reconstitution may be observed. Allow the reconstituted vial to settle for a minute to allow bubbles to dissipate. Do not shake or vigorously swirl. 4.The reconstituted product should be a colorless, clear to slightly opalescent solution with no visible particulates, with a total volume of 11 mL (5 mg/mL). The reconstituted solution should be visually inspected for any particulate matter and discoloration. 10

CONFIDENTIAL Brentuximab vedotin (ADCETRIS™) Reconstitution (cont.) Dose preparation steps (continued): 5.Withdraw the required volume of reconstituted brentuximab vedotin and dilute in an infusion bag containing 0.9% Sodium Chloride Injection There are no known incompatibilities between study treatment and polyvinyl chloride (PVC), ethyl vinyl acetate (EVA), polyolefin, or polyethylene (PE) bags The infusion volume needs to be set such that when the dose of brentuximab vedotin is diluted in the bag, the final drug concentration is between 0.4 and 1.8 mg/mL 6.Gently invert the infusion bag (as applicable); DO NOT SHAKE. 7.Diluted brentuximab vedotin for injection should be administered immediately (if not administered immediately, the in-use storage should not be longer than 24 hours under refrigeration at 2–8°C). 11

CONFIDENTIAL Brentuximab vedotin (ADCETRIS™) Administration In the absence of infusion toxicities, the infusion rate for all patients must be calculated in order to achieve a 30 minute infusion period Note: Compatibility of brentuximab vedotin has not been assessed with in-line filters ADCETRIS™ must: –NOT BE ADMINISTERED AS AN IV PUSH OR BOLUS. –Be administered through a dedicated IV line over 30 minutes –NOT be mixed with other medications 12

CONFIDENTIAL Brentuximab vedotin (ADCETRIS™) Administration (cont.) Infusion-related reactions may occur during the infusion –Patient must be observed for 60 minutes following the first infusion, during which time a functioning IV line must remain to allow administration of IV medications if necessary. –All supportive measures consistent with optimal patient care will be given throughout the study according to institution standards. Medications for infusion-related reactions, such as epinephrine, antihistamines, and corticosteroids, must be available for immediate use. 13

CONFIDENTIAL Supply Management Initial and Resupply Shipments All sites will receive an initial supply of brentuximab vedotin upon activation in IXRS Drug dispensation via IXRS required at each patient visit –Study drug will be assigned by lot number and quantity –IXRS will assign enough study drug for one specific patient visit IXRS will use a threshold resupply model to calculate subsequent shipments CRAs or study management team should be contacted with any concerns regarding study drug inventory 14

CONFIDENTIAL Supply Management Accountability CRAs should collect copy of the site’s guidelines/SOP for local destruction of drug The study pharmacist is responsible for maintaining up-to date written records of study drug inventory and destruction activities Sites should ensure the drug disposition is recorded comprehensively (administration, return, and accountability) on the Overall Investigational Product Inventory Logs (or equivalent) Sites may use their own drug logs if: –The required drug information is captured in the site logs –ICON and/or Millennium have approved the site logs for use –Copies can be collected during routine site monitoring and close out visits (REVIEW OF PHARMACY LOGS AND DOCUMENTS) 15
