1. What is Bortezomib Tarbis and what is it used for

Bortezomib contains the active substance bortezomib, a "proteasome inhibitor". Proteasomes play an important role in controlling cell function and growth. Bortezomib can destroy cancer cells by interfering with their function.

Bortezomib is used to treat multiple myeloma (a type of bone marrow cancer) in patients over 18 years of age:

• alone or with the medicines doxorubicin liposomal pegylated or dexamethasone, for patients whose disease is getting worse (in progression) after receiving at least one previous treatment and for those patients whose stem cell transplant did not work or is not suitable.
• in combination with the medicines melphalan and prednisone, for patients whose disease has not been previously treated and who are not suitable to receive high-dose chemotherapy before a stem cell transplant.
• in combination with the medicines dexamethasone or dexamethasone and thalidomide, in patients whose disease has not been previously treated and who receive high-dose chemotherapy before a stem cell transplant (induction treatment).

Bortezomib is used to treat mantle cell lymphoma (a type of cancer that affects the lymph nodes) in patients over 18 years of age in combination with the medicines rituximab, cyclophosphamide, doxorubicin, and prednisone, in patients whose disease has not been previously treated and for those patients who are not considered suitable for a stem cell transplant.

2. What you need to know before you use Bortezomib Tarbis

Do not use Bortezomib

• if you are allergic to bortezomib, boron, or any of the other ingredients of this medicine (listed in section 6)
• if you have certain severe lung or heart problems.

Warnings and precautions

Tell your doctor if you have:

• low red or white blood cell count
• bleeding problems and/or low platelet count in the blood
• diarrhea, constipation, nausea, or vomiting
• a history of fainting, dizziness, or lightheadedness
• kidney problems
• moderate to severe liver problems
• numbness, tingling, or pain in the hands or feet (neuropathy) in the past
• heart problems or high blood pressure
• difficulty breathing or coughing
• seizures
• shingles (localized, including around the eyes, or widespread)
• symptoms of tumor lysis syndrome, such as muscle cramps, muscle weakness, confusion, vision loss, or difficulty breathing
• memory loss, thought disturbances, difficulty walking, or vision loss. These may be signs of a serious brain infection and your doctor may advise further tests and monitoring.

You will need to have regular blood tests before and during treatment with bortezomib to check your blood cell count regularly.

You must tell your doctor if you have mantle cell lymphoma and are given rituximab with bortezomib:

• if you think you have or have had hepatitis infection in the past. In a few cases, patients who have had hepatitis B can have repeated attacks of hepatitis, which can be fatal. If you have a history of hepatitis B infection, you will be closely monitored by your doctor for signs of active hepatitis B.

Before starting treatment with bortezomib, you should read the package leaflets of all the medicines you need to take with bortezomib to see the information about these medicines.

When using thalidomide, special attention should be paid to pregnancy testing and preventive measures (see Pregnancy and Breast-feeding in this section).

Children and adolescents

Bortezomib should not be used in children and adolescents because it is not known how it will affect them.

Using bortezomib with other medicines

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

In particular, tell your doctor if you are using medicines that contain any of the following active substances:

• ketoconazole, to treat fungal infections
• ritonavir, to treat HIV infection
• rifampicin, an antibiotic to treat bacterial infections
• carbamazepine, phenytoin, or phenobarbital, used to treat epilepsy
• St. John's Wort (Hypericum perforatum), used for depression or other conditions
• oral antidiabetics

Pregnancy and breast-feeding

Do not use bortezomib if you are pregnant unless clearly necessary.

Both men and women using bortezomib must use effective contraception during and up to 3 months after treatment. If, despite these measures, you become pregnant, inform your doctor immediately.

Do not breast-feed while using bortezomib. Ask your doctor when it is safe to restart breast-feeding after finishing your treatment.

Thalidomide causes birth defects and fetal death. When bortezomib is given with thalidomide, you should follow the thalidomide pregnancy prevention program (see the thalidomide package leaflet).

Driving and using machines

Bortezomib may cause fatigue, dizziness, fainting, or blurred vision. Do not drive or use tools or machines if you experience these side effects; even if you do not experience them, you should be cautious.

Bortezomib contains less than 1 mmol of sodium (23 mg) per vial, which is essentially "sodium-free".

3. How to use Bortezomib Tarbis

Your doctor will tell you the dose of bortezomib based on your height and weight (body surface area). The usual starting dose of bortezomib is 1.3 mg/m2 of body surface area twice a week.

Your doctor may change the dose and the total number of treatment cycles depending on your response to treatment, the occurrence of certain side effects, and your underlying condition (e.g., liver problems).

Progressive multiple myeloma

When bortezomib is given alone, you will receive 4 doses of bortezomib by intravenous or subcutaneous injection on days 1, 4, 8, and 11, followed by a 10-day "rest" period without treatment. This 21-day period (3 weeks) is one treatment cycle. You may receive up to 8 cycles (24 weeks).

You may also receive bortezomib with the medicines doxorubicin liposomal pegylated or dexamethasone.

When bortezomib is given with doxorubicin liposomal pegylated, you will receive bortezomib by intravenous or subcutaneous injection in a 21-day treatment cycle and doxorubicin liposomal pegylated 30 mg/m2 will be given on day 4 of the bortezomib 21-day treatment cycle, by intravenous infusion after the bortezomib injection.

You may receive up to 8 cycles (24 weeks).

You may receive up to 8 cycles (24 weeks).

Previously untreated multiple myeloma

If you have not been previously treated for multiple myeloma and are not a candidate for a stem cell transplant, you will receive bortezomib with the medicines melphalan and prednisone.

In this case, the duration of one treatment cycle is 42 days (6 weeks). You will receive 9 cycles (54 weeks).

• In cycles 1 to 4, bortezomib is given twice a week on days 1, 4, 8, 11, 22, 25, 29, and 32.

If you have not received previous treatment for multiple myeloma and are a candidate for a stem cell transplant, you will receive bortezomib by intravenous or subcutaneous injection with the medicines dexamethasone, or dexamethasone and thalidomide, as induction treatment.

When bortezomib is given with dexamethasone, you will receive bortezomib by intravenous or subcutaneous injection in a 21-day treatment cycle and dexamethasone will be given orally at a dose of 40 mg on days 1, 2, 3, 4, 8, 9, 10, and 11 of the bortezomib 21-day treatment cycle. You will receive 4 cycles (12 weeks).

When bortezomib is given with thalidomide and dexamethasone, the duration of one treatment cycle is 28 days (4 weeks).

Dexamethasone 40 mg is given orally on days 1, 2, 3, 4, 8, 9, 10, and 11 of the bortezomib 28-day treatment cycle and thalidomide is given orally once daily at a dose of 50 mg up to day 14 of the first cycle and, if tolerated, the thalidomide dose is increased to 100 mg on days 15-28 and from the second cycle onwards, it may be increased further to 200 mg daily.

You may receive up to 6 cycles (24 weeks).

Previously untreated mantle cell lymphoma

If you have not been previously treated for mantle cell lymphoma, you will receive bortezomib by intravenous or subcutaneous injection with the medicines rituximab, cyclophosphamide, doxorubicin, and prednisone.

Bortezomib is given by intravenous or subcutaneous injection on days 1, 4, 8, and 11, followed by a "rest" period without treatment. The duration of one treatment cycle is 21 days (3 weeks). You may receive up to 8 cycles (24 weeks).

The following medicines are given by intravenous infusion on day 1 of the bortezomib 21-day treatment cycle:

Rituximab at a dose of 375 mg/m2, cyclophosphamide at a dose of 750 mg/m2, and doxorubicin at a dose of 50 mg/m2.

How bortezomib is given

This medicine is given by subcutaneous or, after dilution, intravenous injection. Bortezomib will be given to you by a healthcare professional experienced in the use of cytotoxic medicines.

The solution is then injected into a vein or under the skin. The injection into a vein is rapid, lasting between 3 and 5 seconds. The injection under the skin is given into the thighs or abdomen.

If you receive more bortezomib than you should

This medicine will be given to you by your doctor or nurse, so it is unlikely that you will receive too much. In the unlikely event of an overdose, your doctor will monitor you for side effects.

4. Possible Adverse Effects
