1. What Bortezomib Fresenius Kabi is and what it is used for

This medicine 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 cancer of the bone marrow) 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 blood stem cell transplant did not work or is not suitable.
• in combination with the medicines melphalan and prednisone, for patients who have not been treated before and are not suitable to receive high-dose chemotherapy before a blood stem cell transplant.
• in combination with the medicines dexamethasone or dexamethasone and thalidomide, in patients who have not been treated before and receive high-dose chemotherapy before a blood 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 who have not been treated before and for those patients who are not considered suitable for a blood stem cell transplant.

2. What you need to know before you use Bortezomib Fresenius Kabi

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
• 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, changes in thinking, 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 together 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 have to take in combination with bortezomib to find out about the information related to these medicines.

When using thalidomide, special attention should be paid to pregnancy testing and prevention 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

You should not use this medicine if you are pregnant unless clearly necessary.

Women of childbearing age must use effective contraception during treatment and for up to 8 months after finishing treatment. Talk to your doctor if you wish to freeze your eggs before starting treatment.

Men should not father a child while using bortezomib and must use effective contraception during treatment and for up to 5 months after finishing treatment. Talk to your doctor if you wish to preserve your sperm before starting treatment.

You should 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 in combination 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 still be cautious.

3. How to use Bortezomib Fresenius Kabi

Your doctor will tell you the dose of bortezomib according to 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 by intravenous infusion on day 4 of the bortezomib 21-day treatment cycle, after the bortezomib injection.

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

When bortezomib is given with dexamethasone, you will receive bortezomib by intravenous or subcutaneous injection in a 21-day treatment cycle and dexamethasone 20 mg will be given by mouth on days 1, 2, 4, 5, 8, 9, 11, and 12 of the bortezomib 21-day treatment cycle.

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

Previously untreated multiple myeloma

If you have not been treated before for multiple myeloma and are not a candidate to receive a blood stem cell transplant, you will receive bortezomib with the two other 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.
• In cycles 5 to 9, bortezomib is given once a week on days 1, 8, 22, and 29.

Melphalan (9 mg/m2) and prednisone (60 mg/m2) are given by mouth during days 1, 2, 3, and 4 of the first week of each cycle.

If you have not received any previous treatment for multiple myeloma and are a candidate to receive a blood 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 by mouth 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).

Dexamethasone 40 mg is given by mouth on days 1, 2, 3, 4, 8, 9, 10, and 11 of the bortezomib 28-day treatment cycle and thalidomide is given by mouth 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 from days 15-28 and from the second cycle onwards, it may be further increased to 200 mg daily. You may receive up to 6 cycles (24 weeks).

Previously untreated mantle cell lymphoma

If you have not been treated before 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).

How bortezomib is given

This medicine is given by intravenous or subcutaneous injection. You will be given bortezomib by a healthcare professional who is experienced in the use of cytotoxic medicines.

The bortezomib powder must be dissolved before administration. This will be done by a healthcare professional. The reconstituted 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

Like all medicines, this medicine can cause adverse effects, although not all people suffer from them. Some of these effects can be serious.

If you are administered bortezomib for multiple myeloma or mantle cell lymphoma, report immediately to your doctor if you observe any of the following symptoms:
