1. What Caspofungin Diamed is and what it is used for What Caspofungin Diamed is

Caspofungin Diamed contains the active substance caspofungin. This belongs to a group of medicines called antifungals.

What Caspofungin Diamed is used for

Caspofungin Diamed is used to treat the following infections in children, adolescents and adults:

-    serious fungal infections in your tissues or organs (called “invasive candidiasis”). This infection is caused by fungal (yeast) cells called Candida.

-    People who might get this type of infection include those who have just had an operation or those whose immune systems are weak. Fever and chills that do not respond to an antibiotic are the most common signs of this type of infection.

-    fungal infections in your nose, nasal sinuses or lungs (called “invasive aspergillosis”) if other anti-fungal treatments have not worked or have caused side effects. This infection is caused by a mould called Aspergillus.

-    People who might get this type of infection include those having chemotherapy, those who have had a transplant and those whose immune systems are weak.

-    suspected fungal infections if you have a fever and a low white cell count that have not improved on treatment with an antibiotic. People who are at risk of getting a fungal infection include those who have just had an operation or those whose immune systems are weak.

How Caspofungin Diamed works

Caspofungin Diamed makes fungal cells fragile and stops the fungus from growing properly. This stops the infection from spreading and gives the body’s natural defences a chance to completely get rid of the infection.

2. What you need to know before you are given Caspofungin Diamed Do not use Caspofungin Diamed

- if you are allergic to caspofungin or any of the other ingredients of this medicine (listed in section 6).

If you are not sure, talk to your doctor, nurse or pharmacist before you are given your medicine.

Instructions of how to reconstitute and dilute Caspofungin Diamed:

Reconstitution of Caspofungin Diamed

DO NOT USE ANY DILUENTS CONTAINING GLUCOSE as CASPOFUNGIN DIAMED is not stable in diluents containing glucose. DO NOT MIX OR CO-INFUSE CASPOFUNGIN DIAMED WITH ANY OTHER MEDICINES, as there are no data available on the compatibility of Caspofungin Diamed with other intravenous substances, additives, or medicinal products. Visually inspect the infusion solution for particulate matter or discolouration.

INSTRUCTIONS FOR USE IN ADULT PATIENTS

Step 1 Reconstitution of conventional vials

To reconstitute the powder, bring the vial to room temperature and aseptically add 10.5 ml of water for injection. The concentrations of the reconstituted vials will be 5.2 mg/ml.

The white to off-white compact lyophilised powder will dissolve completely. Mix gently until a clear solution is obtained. Reconstituted solutions should be visually inspected for particulate matter or discolouration. This reconstituted solution may be stored for up to 24 hours at or below 25 °C.

Step 2 Addition of reconstituted Caspofungin Diamed to patient infusion solution

Diluents for the final solution for infusion are: sodium chloride solution for injection, or lactated Ringer’s solution. The solution for infusion is prepared by aseptically adding the appropriate amount of reconstituted concentrate (as shown in the table below) to a 250 ml infusion bag or bottle. Reduced volume infusions in 100 ml may be used, when medically necessary, for 50 mg or 35 mg daily doses. Do not use if the solution is cloudy or has precipitated.

PREPARATION OF THE SOLUTION FOR INFUSION IN ADULTS

DOSE*	Volume of reconstituted Caspofungin Diamed for transfer to intravenous bag or bottle	Standard preparation (reconstituted Caspofungin Diamed added to 250 ml) final concentration	Reduced volume infusion (reconstituted Caspofungin Diamed added to 100 ml) final concentration
50 mg	10 ml	0.20 mg/ml	-
50 mg at reduced volume	10 ml	-	0.47 mg/ml
35 mg for moderate hepatic impairment (from one 50 mg vial)	7 ml	0.14 mg/ml
35 mg for moderate	7 ml	-	0.34 mg/ml

INSTRUCTIONS FOR USE IN PAEDIATRIC PATIENTS

Calculation of Body Surface Area (BSA) for paediatric dosing

Before preparation of infusion, calculate the body surface area (BSA) of the patient using the following formula: (Mosteller¹ Formula)

.*/Height (cm) X Weight (kg)

BSA (m²) = \    3600

Preparation of the 70 mg/m² infusion for paediatric patients >3 months of age (using a 50-mg vial)

1.    Determine the actual loading dose to be used in the paediatric patient by using the patient’s BSA (as calculated above) and the following equation:

BSA (m²) X 70 mg/m² = Loading Dose

The maximum loading dose on Day 1 should not exceed 70 mg regardless of the patient’s calculated dose.

2.    Equilibrate the refrigerated vial of Caspofungin Diamed to room temperature.

3.    Aseptically add 10.5 ml of water for injection.³ This reconstituted solution may be stored for up to 24 hours at or below 25 °C^b This will give a final Caspofungin Diamed concentration in the vial of 5.2 mg/ml.

4.    Remove the volume of medicinal product equal to the calculated loading dose (Step 1) from the vial. Aseptically transfer this volume (ml)^c of reconstituted Caspofungin Diamed to an IV bag (or bottle) containing 250 ml of 0.9 %, 0.45 %, or 0.225 % Sodium Chloride Injection, or Lactated Ringers Injection. Alternatively, the volume (ml)^c of reconstituted Caspofungin Diamed can be added to a reduced volume of 0.9 %, 0.45 %, or 0.225 % Sodium Chloride Injection or Lactated Ringers Injection, not to exceed a final concentration of 0.5 mg/ml. This infusion solution must be used within 24 hours if stored at or below 25 °C or within 48 hours if stored refrigerated at 2 to 8 °C.

Preparation of the 50 mg/m² infusion for paediatric patients >3 months of age (using a 50-mg vial)

1.    Determine the actual daily maintenance dose to be used in the paediatric patient by using the patient’s BSA (as calculated above) and the following equation:

BSA (m2) X 50 mg/m2 = Daily Maintenance Dose

The daily maintenance dose should not exceed 70 mg regardless of the patient’s calculated dose.

2.    Equilibrate the refrigerated vial of Caspofungin Diamed to room temperature.

3.    Aseptically add 10.5 ml of water for injection.⁵¹ This reconstituted solution may be stored for up to 24 hours at or below 25 °C.^b This will give a final Caspofungin Diamed concentration in the vial of 5.2 mg/ml.

4.    Remove the volume of medicinal product equal to the calculated daily maintenance dose (Step 1) from the vial. Aseptically transfer this volume (ml)^c of reconstituted Caspofungin Diamed to an IV bag (or bottle) containing 250 ml of 0.9 %, 0.45 %, or 0.225 % Sodium Chloride Injection, or Lactated Ringers Injection. Alternatively, the volume (ml)^c of reconstituted Caspofungin Diamed can be added to a reduced volume of 0.9 %, 0.45 %, or 0.225 % Sodium Chloride Injection or Lactated Ringers Injection, not to exceed a final concentration of

0.5 mg/ml. This infusion solution must be used within 24 hours if stored at or below 25 °C or within 48 hours if stored refrigerated at 2 to 8 °C.
