1. What is Tomudex and what is it used for

Tomudex contains the active substance raltitrexed which is used for chemotherapy, and belongs to
the class of antimetabolites, folic acid analogues.
Tomudex is used:

• to relieve the symptoms of advanced colorectal cancer
• in association with another medicine (cisplatin), in the treatment of lung cancer (malignant pleural mesothelioma) that cannot be surgically removed in patients who have never been treated with these drugs.

2. What you need to know before using Tomudex

DO NOT use Tomudex

• if you are allergic to raltitrexed or to medicines similar to it or to any of the other components of this medicine (listed in section 6).
• if you suffer from severe kidney dysfunction (creatinine clearance < 25ml/min)
• if you are pregnant or if you are breastfeeding

Warnings and precautions
Consult your doctor or nurse before taking Tomudex.
Tomudex must only be administered by a doctor experienced in anticancer chemotherapy or
otherwise under their supervision.
The doctor will keep you under close observation to identify any adverse reactions, in particular
those relating to the gastrointestinal tract (diarrhea or mucositis) and to the bone marrow (reduction in the number
of white blood cells called neutrophils with a consequent risk of infections, platelets) and will reduce the
dose or delay treatment.

Use Tomudex with caution if:

• you suffer from a reduction in bone marrow function.
• your general health conditions are not good.
• you have undergone radiotherapy.
• you suffer from mild to moderate liver dysfunction
• you are an elderly patient

Before starting therapy and before each subsequent treatment, a complete examination of blood values (white blood cell count and platelets, liver transaminases, bilirubin and
serum creatinine) must be performed

Children
The use of Tomudex is not recommended in children as tolerability and efficacy have not been
evaluated in this patient group.

Other medicines and Tomudex
Tell your doctor or pharmacist if you are taking, have recently taken or might take
any other medicine.
Do not take immediately before or during the administration of Tomudex, other medicines that
may affect its anticancer effect, including:

• folinic acid
• folic acid
• vitamin preparations

Cisplatin
Concomitant use of cisplatin may increase the toxicity of Tomudex, therefore this combination
must be used with caution.

Pregnancy, breastfeeding and fertility
If you are pregnant, suspect you are pregnant, or are planning a pregnancy, or if you are breastfeeding, ask your doctor for advice before being given this medicine.
Pregnancy
You must not be given Tomudex during pregnancy or if potentially at risk of
pregnancy during treatment.
Before starting treatment with Tomudex, it must be ascertained that you are not pregnant.
You should avoid becoming pregnant if either partner is taking Tomudex. It is also recommended
to avoid conception for at least 6 months after the end of treatment.
Breastfeeding
You must not take Tomudex if you are breastfeeding.
Fertility
Studies on fertility in rats indicate that Tomudex may cause inability to conceive in male
rats. Fertility returned to normal after 3 months from the end of therapy.

Driving and operating machinery
You must not drive or operate machinery, due to possible discomfort or muscle weakness after
use of Tomudex.
This medicine contains less than 1 mmol (23 mg) of sodium per vial, i.e. essentially ‘sodium-free’.

3. How to use Tomudex

Tomudex will be administered to you intravenously as a single intravenous infusion lasting
15 minutes by a doctor or nurse. If you have any doubts, consult your doctor, pharmacist or nurse.

Dosage
The dose will be calculated by the doctor based on your body surface area, the specific circumstances
listed in section 2 “Warnings and precautions” and based on your response to treatment and in
the absence of toxicity the treatment may be repeated every 3 weeks.

Use in children
The use of Tomudex is not recommended in children as tolerability and efficacy have not been
evaluated in this patient group.
Patients with renal impairment
For patients with abnormal renal function values (creatinine levels), creatinine
elimination from the blood should be assessed or calculated at the beginning of therapy and before each subsequent
treatment.

If you use more Tomudex than you should
Since this medicine is administered in hospital it is unlikely to be administered in an incorrect quantity.
However, if you have any doubts, talk to your doctor, nurse or pharmacist.

---------------------------------------------------------------------------------------------------------------------------
The following information is intended exclusively for healthcare professionals:
For information on prescribing the medicine, please refer to the Summary of Product Characteristics.
Adult Patients
Before treatment, the total white blood cell count must be greater than 4000/mm³, the neutrophil count
greater than 2000/mm³ and the platelet count greater than 100,000/mm³.
In case of toxicity, the administration of the next dose should be delayed until the signs of the
toxic effects have regressed.
Once the dose has been reduced, all subsequent treatments must be administered at the reduced dose.
The recommended dose is 3 mg/m² diluted in 50 - 250 ml of 0.9% sodium chloride solution or 5% dextrose (glucose) solution and administered intravenously as a single short infusion. It is recommended to
administer the infusion over the course of 15 minutes.
No other drugs should be added to the vial containing the Tomudex solution. In the absence of
toxicity, treatment may be repeated every 3 weeks.
Treatment with Tomudex should be discontinued in case of gastrointestinal toxicity (diarrhea or mucositis)
grade 4 WHO or in case of gastrointestinal toxicity grade 3 WHO associated with hematological toxicity of
grade 4 WHO.
It is essential to observe the dose reduction schedule as the potential lethal or life-threatening toxicity increases if the dose is not reduced or treatment is not discontinued as appropriate.
Cisplatin
When used in combination with Tomudex, cisplatin must be administered after each infusion
of Tomudex. The recommended dose of cisplatin is 80 mg/m² for intravenous infusion over 1-2 hours. In case of
toxicity, the next dose should be suspended until the signs of toxic effects regress,
as with Tomudex. Patients must receive adequate hydration before and after receiving cisplatin
and may require anti-emetic therapy. For these and other recommendations on dosage and method
of administration of cisplatin, refer to the Summary of Product Characteristics for this
medicinal product.
Patients with renal insufficiency
For patients with abnormal creatinine values, creatinine clearance should be assessed or
calculated at the beginning of therapy and before each subsequent treatment.
For patients with normal creatinine values, which may not correlate well with creatinine clearance due to age-related factors or weight loss, the same approach should be followed.
If creatinine clearance is equal to or less than 65 ml/min, the following dose reduction is recommended:
Dosage adjustment in the presence of renal insufficiency
-------------------------------------------------------------------------------------------------------------
Percentage clearance of the 3 mg/m² dose interval between
of creatinine doses
-------------------------------------------------------------------------------------------------------------
> 65 ml/min full dose every 3 weeks
55 to 65 ml/min 75% every 4 weeks
25 to 54 ml/min 50% every 4 weeks
<25 ml min no treatment ----------
---------------------------------------------------------------------------------------------------------------
Patients with hepatic insufficiency
No dosage adjustment is necessary in patients with mild or
moderate hepatic insufficiency. However, since a portion of the drug is excreted via the feces and patients with
hepatic insufficiency usually represent a group with a poor prognosis, treatment should be administered with caution in case of mild or moderate hepatic insufficiency (see section
Precautions for use). Tomudex has not been studied in patients with severe hepatic insufficiency, jaundice
or decompensated hepatic insufficiency and its use in these patients is not recommended.
Instructions for reconstitution and dilution
Tomudex must be reconstituted by adding 4 ml of sterile water for injections to the contents of each vial (containing 2 mg of
raltitrexed) to obtain a 0.5 mg/ml solution.
The individual dose for each patient must be further diluted in 50-250 ml of 0.9% sodium chloride solution or 5% dextrose (glucose) solution and administered as a short intravenous infusion
over 15 minutes.
The chemical and physical stability in use of the diluted infusion solutions has been demonstrated for 24 hours at
25°C under normal light conditions.
Neither Tomudex nor the substances specified for reconstitution or dilution contain preservatives or
bacteriostatic agents.
From a microbiological point of view, the reconstituted and diluted solutions must be used
immediately. If not used immediately, the storage times in use and storage conditions before use are the responsibility of the user and should generally not exceed 12 hours between 2°C and 8°C, unless the reconstitution and dilution have taken place
under controlled and validated aseptic conditions.
It is recommended that the administration of the solution obtained after dilution in 0.9% sodium chloride solution or 5% dextrose (glucose) solution, be started as soon as possible after preparation.
This solution must be used completely within 24 hours of preparing the reconstituted product or discarded.
Reconstituted or diluted solutions do not need to be protected from light.
Do not store partially used vials or reconstituted solutions for subsequent use in the
patient.
Any remaining reconstituted or diluted product must be disposed of according to the procedures provided for
cytotoxins.
Tomudex must be reconstituted by personnel experienced in a designated area for the reconstitution of
cytotoxic agents. Preparations based on cytotoxins such as Tomudex must not be handled by pregnant women.
Reconstitution should normally be carried out in a partial containment facility with
extraction systems such as laminar flow hoods and work surfaces must be covered with
disposable absorbent paper with a plastic backing.
Appropriate protective clothing, including surgical gloves and disposable goggles, must be worn. If
contact with the skin occurs, wash thoroughly with water. In case of accidental splashes in the eyes
irrigate with running water, keeping the eyelids apart, for at least 10 minutes. Consult a doctor.
Any spillage must be cleaned up using standard procedures.
Waste material must be disposed of by incineration according to the procedures provided for
cytotoxic agents.
Overdosage
No clinically tested antidotes are available. In the event of accidental administration of
overdosage, preclinical data suggest considering the administration of folinic acid, which, from clinical experience with other drugs of the same class, can be administered at
a dose of 25 mg/m² intravenously every 6 hours. If the time interval between
administration of Tomudex and folinic acid increases, the effectiveness of the latter in counteracting
toxic effects may decrease.
Manifestations of overdosage can easily be represented by a more severe form of adverse reaction than expected from the administration of the drug. Patients should therefore be
closely monitored for the onset of gastrointestinal and hematological toxicity. Symptomatic treatment and standard supportive measures should be used to treat such toxicities.
