Further information



Kalosso contains the active substance ibandronic acid. This belongs to a group of medicines called
Kalosso is indicated in adults and prescribed to you if you have breast cancer that has spread to your
bones (called bone “metastases”).

It helps to prevent your bones from breaking (fractures).

It helps to prevent other bone problems that may need surgery or radiotherapy.
Kalosso can also be prescribed if you have a raised calcium level in your blood due to a tumour.
Kalosso works by reducing the amount of calcium that is lost from your bones. This helps to stop your
bones from getting weaker.



During treatment your blood may be monitored to ensure that you are receiving the correct dose of
Do not use Kalosso:
if you are allergic (hypersensitive) to the active substance or any of the other ingredients of
if you have, or had in the past low blood calcium. Please consult your doctor.
Take special care with Kalosso:
If you know or believe that you may have hypersensitivity to other bisphosphonates.
Some patients need to be especially careful when using Kalosso. Tell your doctor:



if you have or have ever had kidney problems, kidney failure or have needed dialysis, or if you
have any other disease that may affect your kidneys
if you have any disturbance of mineral metabolism (such as vitamin D deficiency)
You should take calcium and vitamin-D supplements while receiving Kalosso. If you are unable
to do so, you should inform your doctor.
If you are under dental treatment or will undergo dental surgery, tell your dentist that you are
being treated with Kalosso.

Children and adolescents
Kalosso should not be used in children and adolescents below age 18 years.
Using other medicines:
Please inform your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without a prescription.
No interaction was observed when ibandronic acid was administered concomitantly with tamoxifen, or
In particular, tell your doctor or pharmacist if you are receiving a type of antibiotic injection called
“aminoglycoside” such as gentamicin. This is because aminoglycosides and Kalosso can both lower
the amount of calcium in your blood.
Caution should also be paid to the possible existence of simultaneous hypomagnesaemia (reduced
magnesium levels).
Pregnancy and breast-feeding
You should not be given Kalosso if you are pregnant or if you are breast-feeding.
Ask your doctor or pharmacist for advice before taking any medicines.
Driving and using machines:
The effects of Kalosso on the ability to drive or to use machines have not been studied.

------------------------------------------------------------------------------------------------------------------------The following information is intended for medical or healthcare professionals only
Dosage: Prevention of Skeletal Events in Patients with Breast Cancer and Bone Metastases
The recommended dose for prevention of skeletal events in patients with breast cancer and bone
metastases is 6 mg intravenously given every 3-4 weeks. The dose should be infused over at least 15
Patients with renal impairment
For patients with mild renal impairment (CLcr ≥50 and <80 ml/min) no dosage adjustment is
necessary. For patients with moderate renal impairment (CLcr ≥30 and <50 ml/min) or severe renal
impairment (CLcr <30 ml/min) being treated for the prevention of skeletal events in patients with
breast cancer and metastatic bone disease the following dosing recommendations should be followed:
Creatinine Clearance
≥50 CLcr <80

6 mg / 15 minutes

100 ml

4 mg / 1 hour

500 ml



Infusion volume2

≥30 CLcr <50


Dosage / Infusion time1

2 mg / 1 hour

500 ml

Administration every 3 to 4 week
0.9% sodium chloride solution or 5% glucose solution

A 15 minute infusion time has not been studied in cancer patients with CLCr <50 ml/min.
Dosage: Tumour-induced Hypercalcemia
Kalosso is usually administered in a hospital setting. The dose is determined by the doctor considering
the following factors.


Prior to treatment with Kalosso the patient should be adequately rehydrated with 9 mg/ml (0.9%)
sodium chloride. Consideration should be given to the severity of the hypercalcaemia as well as the
tumour type. In most patients with severe hypercalcaemia (albumin-corrected serum calcium* ≥3
mmol/l or ≥12 mg/dl) 4 mg will be an adequate single dosage. In patients with moderate
hypercalcaemia (albumin-corrected serum calcium <3 mmol/l or <12 mg/dl) 2 mg is an effective dose.
The highest dose used in clinical trials was 6 mg but this dose does not add any further benefit in terms
of efficacy.
* Note albumin-corrected serum calcium concentrations are calculated as follows:
serum calcium (mmol/l)
serum calcium (mg/dl)


Serum calcium (mmol/l) - [0.02 x albumin (g/l)] + 0.8


Serum calcium (mg/dl) + 0.8 x [4 - albumin (g/dl)]

To convert the albumin-corrected serum calcium in mmol/l value to mg/dl, multiply by 4.
In most cases a raised serum calcium level can be reduced to the normal range within 7 days. The
median time to relapse (reincrease of serum albumin corrected serum calcium above 3 mmol/l) was
18-19 days for the 2 mg and 4 mg doses. The median time to relapse was 26 days with a dose of 6 mg.
Method and route of administration
Kalosso concentrate for solution for infusion should be administered as an intravenous infusion.
For this purpose the contents of the vial are to be used as follows:
Hypercalcaemia - added to 500 ml isotonic sodium chloride solution or 500 ml 5% glucose
solution and infused over 1-2 hours.
Prevention of Skeletal Events - added to 100 ml isotonic sodium chloride solution or 100 ml 5%
glucose solution and infused over at least 15 minutes. See also dosage section above for patients
with renal impairment.
In order to avoid potential incompatibilities, Kalosso concentrate for solution for infusion should only
be mixed with isotonic sodium chloride solution or with 5% glucose solution. Calcium containing
solutions should not be mixed with Kalosso concentrate for solution for infusion.
Diluted solutions are for single use. Only clear solutions without particles should be used.
It is recommended that the product once diluted be used immediately (see point 5 of this leaflet “HOW
TO STORE Kalosso”).
As the inadvertent intra-arterial administration of preparations not expressly recommended for this
purpose as well as paravenous administration can lead to tissue damage, care must be taken to ensure
that Kalosso concentrate for solution for infusion is administered intravenously.
Frequency of administration
For treatment of tumour induced hypercalcemia, Kalosso concentrate for solution for infusion is
generally given as a single infusion.
For the prevention of skeletal events in patients with breast cancer and bone metastases, the Kalosso
infusion is repeated at 3-4 week intervals.
Duration of treatment
A limited number of patients (50 patients) have received a second infusion for hypercalcaemia.
Repeated treatment may be considered in case of recurrent hypercalcaemia or insufficient efficacy.


For patients with breast cancer and bone metastases, Kalosso infusion should be administered every 34 weeks. In clinical trials, therapy has continued for up to 96 weeks.
Up to now there is no experience of acute poisoning with ibandronic acid concentrate for solution for
infusion. Since both the kidney and the liver were found to be target organs for toxicity in preclinical
studies with high doses, kidney and liver function should be monitored.
Clinically relevant hypocalcaemia (very low serum calcium levels) should be corrected by intravenous
administration of calcium gluconate.
