TEPADINA 200 mg powder and solvent for solution for infusion – patient leaflet, side effects, dosage

1. What TEPADINA is and what it is used for

TEPADINA contains the active substance thiotepa, which belongs to a group of medicines called alkylating agents.

TEPADINA is used to prepare patients for bone marrow transplantation. It works by destroying bone marrow cells. This enables the transplantation of new bone marrow cells (haematopoietic progenitor cells), which in turn enable the body to produce healthy blood cells.

TEPADINA can be used in adults and children and adolescents.

2. What you need to know before you use TEPADINA

Do not use TEPADINA

• if you are allergic to thiotepa,
• if you are pregnant or think you may be pregnant,
• if you are breast-feeding,
• if you are receiving yellow fever vaccination, live virus and bacterial vaccines.

Warning and precautions

You should tell your doctor if you have:

• liver or kidney problems,
• heart or lung problems,
• seizures/fits (epilepsy) or have had them in the past (if treated with phenytoin or fosphenytoin).

Because TEPADINA destroys bone marrow cells responsible for producing blood cells, regular blood tests will be taken during treatment to check your blood cell counts.

In order to prevent and manage infections, you will be given anti-infectives.

TEPADINA may cause another type of cancer in the future. Your doctor will discuss this risk with you.

Other medicines and TEPADINA

Tell your doctor if you are taking, have recently taken or might take any other medicines.

Pregnancy, breast-feeding and fertility

You must tell your doctor if you are pregnant or you think you may be pregnant before you receive TEPADINA. You must not use TEPADINA during pregnancy.

Both women and men using TEPADINA must use effective contraceptive methods during treatment. After cessation of treatment women must use effective contraceptive methods for at least 6 months and men for at least 3 months.

It is not known whether this medicine is excreted in breast milk. As a precautionary measure, women must not breast-feed during treatment with TEPADINA.

TEPADINA can impair male and female fertility. Male patients should seek advice for sperm preservation before therapy is started.

Driving and using machines

It is likely that certain adverse reactions of thiotepa like dizziness, headache and blurred vision could affect your ability to drive and use machines. If you are affected, do not drive or use machines.

TEPADINA contains sodium

This medicine contains 709 mg (30.8 mmol) sodium (main component of cooking/table salt) in each bag. This is equivalent to 35.5% of the recommended maximum daily dietary intake of sodium for an adult.

3. How to use TEPADINA

Your doctor will calculate the dose according to your body surface or weight and your disease.

How TEPADINA is given

TEPADINA is administered by a qualified healthcare professional as an intravenous infusion (drip in a vein) after reconstitution of the individual bag. Each infusion will last 2-4 hours.

Frequency of administration

You will receive your infusions every 12 or 24 hours. The duration of treatment can last up to 5 days. Frequency of administration and duration of treatment depend on your disease.

PREPARATION GUIDE

TEPADINA 200 mg powder and solvent for solution for infusion

Thiotepa

Read this guide prior to the preparation and administration of TEPADINA.

1. 1. PRESENTATION

One bag contains 200 mg thiotepa.

After reconstitution with the solvent, each mL of solution contains 1 mg of thiotepa. TEPADINA must be reconstituted prior to administration.

1. 2. POSOLOGY AND METHOD OF ADMINISTRATION

Calculation of dose of TEPADINA

TEPADINA is administered at different doses in combination with other chemotherapeutic medicinal products in patients prior to conventional haematopoietic progenitor cell transplantation (HPCT) for haematological diseases or solid tumours.

TEPADINA posology is reported, in adult and paediatric patients, according to the type of HPCT (autologous or allogeneic) and disease.

If necessary, dose adjustment of TEPADINA must be operated as per specific application. In case the calculated dose required is higher than 200 mg but less than a multiple thereof, the user is requested to add the required mg from TEPADINA vials by using a dedicated port (luer port) of TEPADINA 200 mg (Step 5 of the Instruction for Use in the package leaflet). In case the calculated dose required is lower than 200 mg the user is requested to remove the unnecessary mg of fully reconstituted 1 mg/mL solution or to set an infusion pump with the amount of medicinal product to be administered in mL.

Activation of the bag and reconstitution

TEPADINA 200 mg must be reconstituted with 200 mL sodium chloride 9 mg/mL (0.9%) solution for injection. The final reconstituted solution is obtained after breaking the peelable seal of the dual chamber bag and mixing the contents (powder and solvent) until complete dissolution of the powder. TEPADINA 200 mg must be reconstituted by applying pressure to mix the contents of the bag and facilitate wettability of all internal surfaces, including corners, port tube and stoppers.

After reconstitution with the solvent, each mL of solution contains 1 mg of thiotepa.

Only colourless solutions, without any particulate matter, must be used.

Do not use this medicine if you notice any visible signs of deterioration.

Administration

TEPADINA infusion solution should be inspected visually for particulate matter prior to administration. Solutions containing a precipitate should be discarded.

The infusion solution must be administered to patients using an infusion set equipped with a 0.2 µm in-line filter. Filtering does not alter solution potency.

TEPADINA should be aseptically administered as a 2-4 hours infusion under room temperature (about 25°C) and normal light conditions.

Prior to and following each infusion, the indwelling catheter line should be flushed with approximately 5 mL sodium chloride 9 mg/mL (0.9%) solution for injection.

1. 3. SPECIAL PRECAUTIONS FOR DISPOSAL AND OTHER HANDLING

General

Procedures for proper handling and disposal of anticancer medicinal products should be considered. All transfer procedures require strict adherence to aseptic techniques, preferably employing a vertical laminar flow safety hood.

As with other cytotoxic compounds, caution need to be exercised in handling and preparation of TEPADINA solutions to avoid accidental contact with skin or mucous membranes. Topical reactions associated with accidental exposure to thiotepa may occur. In fact, the use of gloves is recommended in preparing the solution for infusion. If thiotepa solution accidentally contacts the skin, immediately the skin must be thoroughly washed with soap and water. If thiotepa accidentally contacts mucous membranes, they must be flushed thoroughly with water.

Disposal

TEPADINA is for single use only.

Any unused product or waste material should be disposed of in accordance with local requirements.
