•: Coagulation parameters do not necessarily correlate with or predict the effectiveness of NOVOSEVEN RT.

Treatment of Acute Bleeding Episodes

NOVOSEVEN RT dosing for the treatment of acute bleeding episodes is provided in Table 1.

Table 1: Dosing for Treatment of Acute Bleeding Episodes

Dose* and Frequency	Duration of Therapy	Additional Information
* The minimum effective dose has not been determined
Congenital Hemophilia A or B with Inhibitors
Hemostatic 90 mcg/kg every two hours, adjustable based on severity of bleeding Post-Hemostatic 90 mcg/kg every 3-6 hours for severe bleeds	Until hemostasis is achieved, or until the treatment has been judged to be inadequate After hemostasis is achieved to maintain the hemostatic plug	The appropriate duration of post-hemostatic dosing has not been studied
Acquired Hemophilia
70-90 mcg/kg every 2-3 hours	Until hemostasis is achieved
Congenital Factor VII Deficiency
15-30 mcg/kg every 4-6 hours	Until hemostasis is achieved	Effective treatment has been achieved with doses as low as 10 micrograms per kg body weight. Adjust dose and frequency of injections to each individual patient
Glanzmann’s Thrombasthenia
90 mcg/kg every 2-6 hours	In severe bleeding episodes requiring systemic hemostatic therapy until hemostasis is achieved	Platelet transfusions are the primary treatment in patients with Glanzmann’s Thrombasthenia without refractoriness to platelets or in patients without platelet-specific antibodies

Congenital Hemophilia A or B with inhibitors

•: Dose and administration interval may be adjusted to the individual patient based on the severity of the bleeding.1
•: For patients treated for joint or muscle bleeds, a decision on outcome was reached for a majority of patients within eight doses although more doses were required for severe bleeds. A majority of patients who reported adverse experiences received more than twelve doses. Monitor and minimize the duration of any post-hemostatic dosing.

Perioperative Management

NOVOSEVEN RT dosing for prevention of bleeding in surgical interventions or invasive procedures (perioperative management) is provided in Table 2.

Reconstitution

•: Follow the procedures below for the preparation and reconstitution of NOVOSEVEN RT. For questions regarding reconstitution, please contact Novo Nordisk at 1-877-NOVO-777.
•: Calculate the NOVOSEVEN RT dosage and select the appropriate NOVOSEVEN RT package provided with either 1 histidine diluent vial or 1 pre-filled histidine diluent syringe.
•: Reconstitute only with the histidine diluent provided with NOVOSEVEN RT.

NOVOSEVEN RT package containing 1 vial of NOVOSEVEN RT powder and 1 vial of histidine diluent:

1.: Always use aseptic technique.
2.: Bring NOVOSEVEN RT (white, lyophilized powder) and the specified volume of histidine (diluent) to room temperature, but not above 37°C (98.6° F). The specified volume of diluent corresponding to the amount of NOVOSEVEN RT is as follows:
1 mg (1000 micrograms) vial + 1.1 mL Histidine diluent
2 mg (2000 micrograms) vial + 2.1 mL Histidine diluent
5 mg (5000 micrograms) vial + 5.2 mL Histidine diluent
8 mg (8000 micrograms) vial + 8.1 mL Histidine diluent
3.: Remove caps from the NOVOSEVEN RT vials to expose the central portion of the rubber stopper. Cleanse the rubber stoppers with an alcohol swab and allow to dry prior to use.
4.: Draw back the plunger of a sterile syringe (attached to sterile needle) and admit air into the syringe. It is recommended to use syringe needles of gauge size 20-26.
5.: Insert the needle of the syringe into the Histidine diluent vial. Inject air into the vial and withdraw the quantity required for reconstitution.
6.: Insert the syringe needle containing the diluent into the NOVOSEVEN RT vial through the center of the rubber stopper, aiming the needle against the side so that the stream of liquid runs down the vial wall (the NOVOSEVEN RT vial does not contain a vacuum). Do not inject the diluent directly on the NOVOSEVEN RT powder.
7.: Gently swirl the vial until all the material is dissolved. The reconstituted solution is a clear, colorless solution which may be stored either at room temperature or refrigerated for up to 3 hours after reconstitution. After reconstitution with the specified volume of diluent, each vial contains approximately 1 mg per mL NOVOSEVEN RT (1000 micrograms per mL).

NOVOSEVEN RT package containing 1 vial of NOVOSEVEN RT powder and 1 pre-filled histidine diluent syringe with vial adapter for needleless reconstitution:

1.: Always use aseptic technique.
2.: Bring NOVOSEVEN RT (white, lyophilized powder) and the specified volume of histidine (diluent) to room temperature, but not above 37°C (98.6° F). The specified volume of diluent corresponding to the amount of NOVOSEVEN RT is as follows:
1 mg (1000 micrograms) vial + 1 mL Histidine diluent in pre-filled syringe
2 mg (2000 micrograms) vial + 2 mL Histidine diluent in pre-filled syringe
5 mg (5000 micrograms) vial + 5 mL Histidine diluent in pre-filled syringe
8 mg (8000 micrograms) vial + 8 mL Histidine diluent in pre-filled syringe
3.: Remove cap from the NOVOSEVEN RT vial. Cleanse the rubber stopper with an alcohol swab and allow to dry prior to use.
4.: Peel back the protective paper from the vial adapter. Do not remove the vial adapter from the package.
5.: Place the NOVOSEVEN RT vial on a flat surface. While holding the vial adapter package, place the vial adapter over the NOVOSEVEN RT vial and press down firmly on the package until the vial adapter spike penetrates the rubber stopper.
6.: Attach the plunger rod to the syringe. Turn the plunger rod clockwise into the plunger inside the pre-filled diluent syringe until resistance is felt. Remove the syringe cap from the pre-filled diluent syringe and screw onto the vial adapter.
7.: Push the plunger rod to slowly inject all the diluent into the vial. Keep the plunger rod pressed down and swirl the vial gently until the powder is dissolved. The reconstituted solution is a clear, colorless solution which may be stored fully assembled either at room temperature or refrigerated for up to 3 hours after reconstitution. After reconstitution with the specified volume of diluent, each vial contains approximately 1 mg per mL NOVOSEVEN RT (1000 micrograms per mL).

Administration

For intravenous injection only

•: Inspect the reconstituted NOVOSEVEN RT visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if particulate matter or discoloration is observed.
•: Do not freeze reconstituted NOVOSEVEN RT or store it in syringes.
•: Administer within 3 hours after reconstitution.
•: Do not mix with other infusion solutions.
•: Discard any unused solution.

Perform the following procedures immediately prior to administration:

NOVOSEVEN RT package containing 1 vial of NOVOSEVEN RT powder and 1 vial of histidine diluent:

: 1. Always use aseptic technique.
: 2. Draw back the plunger of a sterile syringe (attached to sterile needle) and admit air into the syringe.
: 3. Insert needle into the vial of reconstituted NOVOSEVEN RT. Inject air into the vial and then withdraw
: the appropriate amount of reconstituted NOVOSEVEN RT into the syringe.
: 4. Remove and discard the needle from the syringe.

NOVOSEVEN RT package containing 1 vial of NOVOSEVEN RT powder and 1 pre-filled histidine diluent syringe with vial adapter for needleless reconstitution:
