Contents of the pack and other information

1. What Kappalkyl is and what it is used for
Kappalkyl is a medicine which is used for the treatment of certain types of cancer (cytotoxic medicine).
Kappalkyl is used alone (monotherapy) or in combination with other medicines for the treatment of the
following forms of cancer:
chronic lymphocytic leukaemia in cases where fludarabine combination chemotherapy is not
appropriate for you,
non-Hodgkin lymphomas, which had not, or only shortly, responded to prior rituximab treatment,



multiple myeloma in cases where high-dose chemotherapy with autologous stem cell
transplantation, thalidomide or bortezomib containing therapy is not appropriate for you.

What you need to know before you use Kappalkyl

Do not use Kappalkyl

if you are allergic to bendamustine hydrochloride or any of the other ingredients of this medicine
(listed in section 6);


while breast-feeding;
if you have severe liver dysfunction (damage to the functional cells of the liver);
if you have yellowing of the skin or whites of the eyes caused by liver or blood problems



if you have severely disturbed bone marrow function (bone marrow depression) and serious
changes in your number of white blood cells and platelets in the blood (white blood cells and/or
platelet values dropped to < 3,000/µl or < 75,000/µl, respectively.);


if you have had major surgical operations less than 30 days before starting treatment;


if you have an infection, especially one accompanied by a reduction in white blood cells
in combination with yellow fever vaccines.

Warnings and precautions
Talk to your doctor, pharmacist or nurse before using Kappalkyl



in case of reduced capability of the bone marrow to replace blood cells. You should have your
number of white blood cells and platelets in the blood checked before starting treatment with
Kappalkyl, before each subsequent course of treatment and in the intervals between courses of
in case of infections. You should contact your doctor if you have signs of infection, including
fever or lung symptoms.
in case of reactions on your skin during treatment with Kappalkyl. The reactions may increase in
in cases of existing heart disease (e.g. heart attack, chest pain, severely disturbed heart rhythms).
in case you notice any pain in your side, blood in your urine or reduced amount of urine. When
your disease is very severe, your body may not be able to clear all the waste products from the
dying cancer cells. This is called tumour lysis syndrome and can cause kidney failure and heart
problems within 48 hours of the first dose of Kappalkyl. Your doctor will be aware of this and
may give you other medicines to help prevent it.
in case of severe allergic or hypersensitivity reactions. You should pay attention to infusion
reactions after your first cycle of therapy.

Men receiving treatment with Kappalkyl are advised not to conceive a child during treatment and for up
to 6 months afterwards. Before starting treatment, you should seek advice on storing sperm because of the
possibility of permanent infertility.
Unintentional injection into the tissue outside blood vessels (extravasal injection) should be stopped
immediately. The needle should be removed after a short aspiration. Thereafter the affected area of tissue
should be cooled. The arm should be elevated. Additional treatments like the use of corticosteroids are
not of clear benefit (see section 4).
Children and adolescents
There is no experience in children and adolescents with Kappalkyl.
Other medicines and Kappalkyl
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
If Kappalkyl is used in combination with medicines which inhibit the formation of blood in the bone
marrow, the effect on the bone marrow may be intensified.
If Kappalkyl is used in combination with medicines which alter your immune
response, this effect may be intensified.
Cytostatic medicines may diminish the effectiveness of live-virus vaccination. Additionally cytostatic
medicines increase the risk of an infection after vaccination with live vaccines (e.g. viral vaccination).
Pregnancy, breastfeeding and fertility
If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your
doctor or pharmacist for advice before using this medicine.

Kappalkyl can cause genetic damage and has caused malformations in animal studies. You should not use
Kappalkyl during pregnancy unless clearly indicated by your doctor. In case of treatment you should have
medical consultation about the risk of potential adverse effects of your therapy for the unborn child and
genetic consultation is recommended.
If you are a woman of childbearing potential you must use an effective method of contraception both
before and during treatment with Kappalkyl. If pregnancy occurs during your treatment with Kappalkyl
you must immediately inform your doctor and should have genetic consultation.
Kappalkyl must not be administered during breastfeeding. If treatment with Kappalkyl is necessary
during lactation you must discontinue breastfeeding.
If you are a man, you should avoid fathering a child during treatment with Kappalkyl and for up to 6
months after treatment has stopped. There is a risk that treatment with Kappalkyl will lead to infertility
and you may wish to seek advice on storing of sperm before treatment starts.

Driving and using machines
No studies on the effects on the ability to drive and to use machines have been performed. Do not drive
or operate machines if you experience side effects, such as dizziness or lack of coordination.

3. How to use Kappalkyl
Kappalkyl is administered into a vein over 30-60 minutes in various dosages, either alone (monotherapy)
or in combination with other medicines.
Treatment should not be started if your white blood cells (leukocytes) have fallen to counts below 3,000
cells/µl and/or your blood platelets have fallen to counts below 75,000 cells/µl.
Your doctor will determine these values at regular intervals.
Chronic lymphocytic leukaemia
Kappalkyl 100 mg per square metre of your body surface area (based on
your height and weight)

on Days 1+2

Repeat the cycle after 4 weeks
Non-Hodgkin lymphomas
Kappalkyl 120 mg per square metre of your body surface area (based
on your height and weight)

on Days 1 + 2

Repeat the cycle after 3 weeks
Multiple myeloma
Kappalkyl 120 - 150 mg per square metre of your body surface area
(based on your height and weight)
Prednisone 60 mg per square metre of your body surface area (based
on your height and weight) intravenous or orally

on Days 1 + 2
on Days 1 - 4

Repeat the cycle after 4 weeks
Treatment should be terminated if white blood cell (leukocyte) and/or platelet values dropped to <

3,000/µl or < 75,000/µl, respectively. Treatment can be continued after white blood cell values have
increased to > 4,000/µl and platelet values to > 100,000/µl.
Impaired liver or kidney function
Dependent on the degree of impairment of your liver function it may be necessary to adjust your dose (by
30% in case of moderate liver dysfunction). Kappalkyl should not be used if you suffer from severe liver
dysfunction. No dose adjustment is necessary in case of impairment of kidney function. Your attending
doctor will decide whether a dosage adjustment is necessary.
How it is administered
Treatment with Kappalkyl should be undertaken only by doctors experienced in tumour therapy. Your
doctor will give you the exact dose of Kappalkyl and use the necessary precautions.
Your attending doctor will administer the solution for infusion after preparation as prescribed. The
solution is administered into a vein as a short-term infusion over 30 - 60 minutes.
Duration of use

If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.

4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.

Tissue changes (necrosis) have been observed very rarely following unintentional injection into the tissue
outside blood vessels (extravascular). A burning sensation where the infusion needle is inserted may be a
sign for administration outside the blood vessels. The consequence of administration in this way can be
pain and poorly healing skin defects.
The dose-limiting side-effect of Kappalkyl is impaired bone-marrow function, which usually returns to
normal after treatment. Suppressed bone marrow function increases the risk of infection.

This leaflet was last revised in 11/2015.

The following information is intended for healthcare professionals only:
As with all similar cytotoxic substances, stricter safety precautions apply as far as nursing staff and
doctors are concerned, due to the potentially genome-damaging and cancer-causing effect of the
preparation. Avoid inhalation (breathing in) and contact with the skin and mucous membranes when
handling Kappalkyl (wear gloves, protective clothing, and possibly a face mask!). If any parts of the body
become contaminated, clean them carefully with soap and water, and flush the eyes with 0.9% w/v saline
solution. If possible, it is advisable to work on a special safety work bench (laminar flow) with a
disposable absorbent sheet that is impermeable to liquids. Contaminated articles are cytostatic waste.
Please comply with national guidelines on the disposal of cytostatic material! Pregnant staff must be
excluded from working with cytostatics. The vials are for single use only.
The solution ready for use must be prepared by dissolving the contents of an injection vial of Kappalkyl
exclusively in water for Injections, as follows:
1. Preparation of the concentrate
• One injection vial of Kappalkyl containing 25 mg of bendamustine hydrochloride is first
dissolved in 10 ml by shaking
• One injection vial of Kappalkyl containing 100 mg of bendamustine hydrochloride is first
dissolved in 40 ml by shaking
2. Preparation of the solution for infusion
As soon as a clear solution is obtained (generally after 5 - 10 minutes), the total recommended dose of
Kappalkyl is immediately diluted with 0.9% w/v saline solution to obtain a final volume of approximately
500 ml. Kappalkyl must not be diluted with other solutions for infusion or injection. Kappalkyl must not
be mixed in an infusion with other substances.
