Intradermal skin test

Because of the occurrence of allergic reactions, an intradermal skin test should

be performed prior to the initial administration of KIDROLASE and when

KIDROLASE is given after an interval of a week or more has elapsed between

doses. The skin test solution may be prepared as follows: Reconstitute the

contents of a 10,000 I.U. vial with 5.0ml of diluent. From this solution (2,000

I.U./ml) withdraw 0.1 ml and inject it into another vial containing 9.9ml of diluent,

yielding a skin test solution of approximately 20.0 I.U./ml. Use 0.1 ml of this

solution (about 2.0 I.U.) for the intradermal skin test. The skin test site should be

observed for at least one hour for the appearance of a wheal or erythema either

of which indicates a positive reaction. An allergic reaction even to the skin test

dose in certain sensitized individuals may rarely occur. A negative skin test

reactoion does not preclude the possibility of the development of an allergic



Desensitization should be performed before administering the first dose of

KIDROLASE on initiation of therapy in positive reactors, and on retreatment of

any patient in whom such therapy is deemed necessary after carefully weighing

the increased risk of hypersensitivity reactions. Rapid desensitization of the

patient may be attempted with progressively increasing amounts of intravenously

administered KIDROLASE provided adequate precautions are taken to treat an

acute allergic reaction should it occur. One reported schedule begins with a total

of 1 I.U. given intravenously and doubles the dose every 10 minutes, provided no

reaction has occurred, until the accumulated total amount given equals the

planned doses for that day.

4.3. Contraindications

- Known hypersensitivity to the active substance or to any of the excipients listed

in section 6.1. Similarly, a hypersensitivity reaction during treatment

contraindicates the continuation of treatment.

- Hepatic failure

- pancreatitis (see section 4.4).

- In combination with a live attenuated vaccine and until at least six months after

stopping chemotherapy (see section 4.5).

4.4 Special Warnings and precautions for use

Kidrolase should only be used by physicians who specialize in this type of


Anaphylactic reactions have been observed after using Kidrolase.

Administration of this medicinal product must be performed in a healthcare

facility, in the presence of trained personnel and the resources necessary

to ensure treatment of an anaphylactic reaction that may occur during


Re-administering L-asparaginase after a period of time (for example,

between the induction phase and the consolidation phase) may increase

the risk of occurrence of an anaphylactic reaction. Close monitoring is

recommended in these conditions.

Posterior Reversible Encephalopathy Syndrome (PRES) may occur rarely during

treatment with any asparaginase (see section 4.8). This syndrome is

characterised in magnetic resonance imaging (MRI) by reversible (from a few

days to months) lesions/oedema, primarily in the posterior region of the brain.

Symptoms of PRES essentially include elevated blood pressure, seizures,

headaches, changes in mental state and acute visual impairment (primarily

cortical blindness or homonymous hemianopsia). It is unclear whether the PRES

is caused by asparaginase, concomitant treatment or the underlying diseases.

PRES is treated symptomatically, including measures to treat any seizures.

Discontinuation or dose reduction of concomitantly administered

immunosuppressive medicinal products may be necessary. Expert advice should

be sought.

During reinduction, administer corticosteroid therapy for 24 to 48 hours to

prevent allergic reactions.

Close monitoring before and during treatment is necessary:

Blood lipase and blood glucose levels should be monitored to look

for pancreatitis or hyperglycaemia. Treatment must be discontinued

if there is an increase in blood lipase levels during treatment. This

treatment may exacerbate diabetes. Hyperglycaemia can be

treated with insulin, if needed.

Coagulation tests should be performed before treatment and

repeated during treatment before each injection of KIDROLASE (at

least aPTT, PT, fibrinogen assay, antithrombin III (AT III) assay).

Replacement therapy should be performed if fibrinogen is below 1

g/litre or if AT III is below 60%. If the fibrinogen or AT III levels do

not increase, or if a significant bleeding disorder appears, it is

preferable to temporarily interrupt treatment and it should not be

resumed until after laboratory parameters have returned to normal.

Regular liver function tests will be performed throughout the entire

duration of treatment, as will full blood counts.

Renal function and serum uric acid levels must be monitored.


This medicinal product is not recommended with phenytoin or fosphenytoin and

methotrexate. In patients treated with phenytoin, administration of an

anticonvulsant benzodiazepine should be considered to avoid a risk of seizures

related to a reduction of gastrointestinal absorption of phenytoin induced by

cytotoxic agents (see section 4.5).

4.6. Fertility, pregnancy and lactation

The data on use of L-asparaginase in pregnant women are limited.

Studies conducted in animals are insufficient for making conclusions about the

reproductive toxicity of KIDROLASE (see section 5.3).

KIDROLASE is not recommended during pregnancy and in women of

childbearing age who do not use contraception.


It is uncertain whether KIDROLASE is exerted in breast milk. Therefore,

breastfeeding is not recommended during treatment with KIDROLASE.


No fertility data are available.

4.7. Effects on the ability to drive a vehicle and operate machinery

Not applicable.

4.8. Undesirable effects

The two most common adverse effects are:

Immediate hypersensitivity reactions, including urticaria, laryngeal

oedema, bronchospasm, hypotension and even anaphylactic shock. In

case of hypersensitivity reaction, treatment must be immediately and

definitively stopped (see section 4.3).

Thromboembolic events resulting from the effects of asparaginase on

clotting protein synthesis, are the second most common class of adverse

effects. They may be fatal or result in sequelae based on their location.

The disease itself and the presence of a central venous catheter

contribute to increasing thromboembolic risk.

Adverse effects are generally reversible.

The adverse effects spontaneously reported as well as those reported in the

literature in patients treated with L-asparaginase as part of their chemotherapy

protocol are listed in the table below. The adverse effects are classified by

system organ class and frequency.

The frequencies below are defined using the following convention:

Very common (≥ 1/10); Common (≥ 1/100 - < 1/10); Uncommon (≥ 1/1,000 - <

1/100); Rare (≥ 1/10,000 - < 1/1,000); Very rare (< 1/10,000), Not known.

- Resulting from the inhibition of protein synthesis.

- Seizures may be associated with cases of thrombosis or metabolic


- Resulting from excessive ammonia production by the action of L-asparaginase

on endogenous asparagine and glutamine.

- These symptoms are commonly associated with hypersensitivity reactions.

Description of selected adverse effects

Pancreatic disorders – Acute pancreatitis occurs in less than 10% of cases.

Isolated cases of pseudocyst formation have been reported up to 4 months after

the last administration of treatment; relevant exams (e.g. ultrasound) may be

considered after the last administration of treatment. Very rare cases of

haemorrhagic or necrotising pancreatitis occur and may be fatal. L-asparaginase

may affect endocrine function. Hyperglycaemia is the most commonly reported

adverse effect and it is easy to control it by administering insulin. Rare cases of

diabetic ketoacidosis have been reported.

Nervous system disorders and cardiac disorders observed on Kidrolase are often

the result of a thromboembolic event or may be promoted by the concomitant

prescriptions of cancer drugs.

In rare cases, a posterior reversible encephalopathy syndrome (PRES) has been

observed during therapy with asparaginase-containing regimens.

(For information

on precautions for use, see section 4.4).

Paediatric population

There is no known antidote for asparaginase overdoses. No data are available

on the elimination (peritoneal or by haemodialysis) of the product.


Pharmaceutical properties

5.1. Pharmacodynamic properties

Pharmacotherapeutic group: OTHER ANTINEOPLASTIC AGENT

ATC Code: L01XX02

L-asparaginase is a protein enzyme extracted from

Escherichia coli

cultures. It

destroyes asparagine by hydrolysis. This amino acid is a basic component of

cellular protein; leukemia cells, which cannot synthesise this amino acid

themselves, must use extracellular asparagine.

Given that extracellular aspargine is hydrolysed by L- asparginase, this

deficiency leads to the destruction of cells that are unable to endogenously

synthesise aspargine.

Given this particular mechanism of action, there is no cross-resistance with other

cytostatic agents.

5.2. Pharmacokinetic properties

Asparginase is poorly distributed in tissue; its half-life is biphasic and varies

between 8 and 30 hours, depending on subjects; 24 hours after IV injection of

1,000 IU/kg, the plasma level is between 8 and 20 IU/mL; after IM injection, the

plasma level observed is 50% lower.

5.3 Preclinical safety data

The following effects have been observed in animals after intravenous injection,

leading to exposure rates similar to those observed in clinical practice: reversible

hepatotoxicity, resorption and significant foetal abnormalities in New Zealand

white rabbits, delayed growth and development, but also malformations of rat

embryos treated in vitro.
