2.5 Preparation and Administration of BLINCYTO

It is very important that the instructions for preparation (including admixing) and administration provided in this section are strictly followed to minimize medication errors (including underdose and overdose) [see Warnings and Precautions (5.13) – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information].

BLINCYTO can be infused over 24 hours, 48 hours, 72 hours or 96 hours. The choice between these options for the infusion duration should be made by the treating healthcare provider considering the frequency of the infusion bag changes and the weight of the patient.

For preparation, reconstitution, and administration of BLINCYTO:

• See Section 2.6 for infusion over 24 hours, 48 hours, 72 hours or 96 hours using 0.9% Sodium Chloride.

The preparation steps differ based on the infusion duration. Follow the steps specific to the infusion duration you are preparing.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

2.5.1 Aseptic Preparation

Strictly observe aseptic technique when preparing the solution for infusion since BLINCYTO vials do not contain antimicrobial preservatives. To prevent accidental contamination, prepare BLINCYTO according to aseptic standards, including but not limited to:

• Prepare BLINCYTO in a USP <797> compliant facility.

• Prepare BLINCYTO in an ISO Class 5 laminar flow hood or better.

• Ensure that the admixing area has appropriate environmental specifications, confirmed by periodic monitoring.

• Ensure that personnel are appropriately trained in aseptic manipulations and admixing of oncology drugs.

• Ensure that personnel wear appropriate protective clothing and gloves.

• Ensure that gloves and surfaces are disinfected.

2.5.2 Package Content

One package BLINCYTO includes one vial of BLINCYTO and one vial of IV Solution Stabilizer.

• Do not use IV Solution Stabilizer for reconstitution of BLINCYTO. IV Solution Stabilizer is provided with the BLINCYTO package and is used to coat the intravenous bag prior to addition of reconstituted BLINCYTO to prevent adhesion of BLINCYTO to intravenous bags and intravenous tubing.

• More than one vial of BLINCYTO may be needed to prepare the recommended dose.

2.5.3 Incompatibility Information

BLINCYTO is incompatible with di-ethylhexylphthalate (DEHP) due to the possibility of particle formation, leading to a cloudy solution.

• Use polyolefin, DEHP-free PVC, or ethyl vinyl acetate (EVA) infusion bags/pump cassettes.

• Use polyolefin, DEHP-free PVC, or EVA intravenous tubing sets.

2.6 Preparation and Administration of BLINCYTO as a 24-Hour, 48-Hour, 72-Hour or 96-Hour Infusion

Reconstitute BLINCYTO with preservative-free Sterile Water for Injection. Do not reconstitute BLINCYTO vials with the IV Solution Stabilizer.

To prime the intravenous tubing, use only the solution in the bag containing the FINAL prepared BLINCYTO solution for infusion. Do not prime with 0.9% Sodium Chloride.

2.6.1 Reconstitution of BLINCYTO for 24-Hour, 48-Hour, 72-Hour or 96-Hour Infusion

1. Determine the number of BLINCYTO vials needed for a dose and infusion duration.

2. Reconstitute each BLINCYTO vial with 3 mL of preservative-free Sterile Water for Injection by directing the water along the walls of the BLINCYTO vial and not directly on the lyophilized powder. The resulting concentration per BLINCYTO vial is 12.5 mcg/mL.

   • Do not reconstitute BLINCYTO vials with IV Solution Stabilizer.

3. Gently swirl contents to avoid excess foaming.

   • Do not shake.

4. Visually inspect the reconstituted solution for particulate matter and discoloration during reconstitution and prior to preparing the intravenous bag. The resulting solution should be clear to slightly opalescent, colorless to slightly yellow.

   • Do not use if solution is cloudy or has precipitated.

2.6.2 Preparation of BLINCYTO Infusion for 24-Hour, 48-Hour, 72-Hour or 96-Hour Infusion Bag

Verify the prescribed dose and infusion duration for each BLINCYTO infusion bag. To minimize errors, use the specific volumes described in Tables 5 and 6 to prepare the BLINCYTO infusion bag.

• Table 5 for patients weighing 45 kg or more

• Table 6 for patients weighing less than 45 kg

1. Aseptically add 270 mL of 0.9% Sodium Chloride to the empty intravenous bag.

2. Aseptically transfer 5.5 mL IV Solution Stabilizer to the intravenous bag containing 0.9% Sodium Chloride Injection, USP. Gently mix the contents of the bag to avoid foaming. Discard the vial containing the unused IV Solution Stabilizer.

3. Aseptically transfer the required volume of reconstituted BLINCYTO solution into the intravenous bag containing 0.9% Sodium Chloride Injection, USP and IV Solution Stabilizer. Gently mix the contents of the bag to avoid foaming.

   • Refer to Table 5 for patients weighing 45 kg or more for the specific volume of reconstituted BLINCYTO.

   • Refer to Table 6 for patients weighing less than 45 kg (dose based on BSA) for the specific volume of reconstituted BLINCYTO.

   • Discard the vial containing unused BLINCYTO.

4. Remove air from the intravenous bag. This is particularly important for use with an ambulatory infusion pump.

5. Under aseptic conditions, attach the intravenous tubing to the intravenous bag with the sterile 0.2 micron in-line filter. Ensure that the intravenous tubing is compatible with the infusion pump.

6. Prime the intravenous tubing only with the solution in the bag containing the FINAL prepared BLINCYTO solution for infusion.

7. Store refrigerated at 2°C to 8°C if not used immediately [see Dosage and Administration (2.7)].

2.6.3 Administration of BLINCYTO for 24-Hour, 48-Hour, 72-Hour or 96-Hour Infusion Bag

• Administer BLINCYTO as a continuous intravenous infusion at a constant flow rate using an infusion pump. The pump should be programmable, lockable, non-elastomeric, and have an alarm.

• The starting volume (270 mL) is more than the volume administered to the patient (240 mL) to account for the priming of the intravenous tubing and to ensure that the patient will receive the full dose of BLINCYTO.

• Administer prepared BLINCYTO final infusion solution using intravenous tubing that contains a sterile, non-pyrogenic, low protein-binding, 0.2 micron in-line filter.

• Infuse prepared BLINCYTO final infusion solution according to the instructions on the pharmacy label on the prepared bag at one of the following constant infusion rates:

  • Infusion rate of 10 mL/hour for a duration of 24 hours, OR

  • Infusion rate of 5 mL/hour for a duration of 48 hours, OR

  • Infusion rate of 3.3 mL/hour for a duration of 72 hours, OR

  • Infusion rate of 2.5 mL/hour for a duration of 96 hours

• Administer prepared BLINCYTO final infusion solution using intravenous tubing that contains a sterile, non-pyrogenic, low protein-binding, 0.2 micron in-line filter.

• Important Note: Do not flush the BLINCYTO infusion line, especially when changing infusion bags. Flushing when changing bags or at completion of infusion can result in excess dosage and complications thereof. When administering via a multi-lumen venous catheter, infuse BLINCYTO through a dedicated lumen. Before flushing the catheter system, residual amounts of BLINCYTO must be aspirated from the catheter system to avoid bolus administration.

• At the end of the infusion, discard any unused BLINCYTO solution in the intravenous bag and intravenous tubing in accordance with local requirements.
