For doctors

 

What is it and how is it used?

Your doctor has prescribed TORISEL because you have one of the following types of cancer:

TORISEL is a selective inhibitor of mTOR (mammalian target of rapamycin) that blocks tumour cell growth and division.

What do you have to consider before using it?

Do not use TORISEL

Take special care with TORISEL

TORISEL may also

Using TORISEL with other medicines

Some medicines can interfere with the breakdown or metabolism of TORISEL. In particular, you should inform your doctor if you are taking any of the following:

Using TORISEL with food and drink

Please tell your doctor if you are taking, or have recently taken, any other medicines, including medicines obtained without a prescription.

Pregnancy and breast-feeding

TORISEL has not been studied in pregnant women, and it must not be used during pregnancy. It is important that you tell your doctor if you are pregnant or are planning to become pregnant before receiving TORISEL.

Women of childbearing potential must avoid pregnancy by using an effective method of birth control during treatment with TORISEL. Men with partners of childbearing potential should use medically acceptable contraception while receiving TORISEL.

Women should not breast-feed during treatment with TORISEL, as this medicine may interfere with the growth and development of the baby. Ask your doctor for advice before breast-feeding your baby, as it is not known if TORISEL passes into breast milk.

Driving and using machines

No studies on the ability to drive and use machines have been performed. However, the very common side effects include feeling or being sick (nausea and vomiting) and difficulty falling or staying asleep. It is recommended you do not drive immediately after treatment.
For patients receiving the higher dose of TORISEL for the treatment of mantle cell lymphoma, the amount of alcohol in this medicinal product may impair your ability to drive or use machines.

Important information about some of the ingredients of TORISEL

This medicine contains ethanol (alcohol), equivalent to 17.6 ml beer, 7.3 ml wine per 25 mg dose. Patients receiving the higher dose of 175 mg of TORISEL for the initial treatment of mantle cell lymphoma may receive a dose of ethanol equivalent to up to 123 ml beer or 51 ml wine per dose. Harmful for those suffering from alcoholism. To be taken into account in pregnant or breast-feeding women, children and high-risk groups such as patients with liver disease or epilepsy. The amount of alcohol in this medicinal product may alter the effects of other medicines.

Children and adolescents

Insufficient data are available in patients under the age of 18 years. The treatment with this medicine is not recommended in children and adolescents.

How is it used?

TORISEL will always be prepared and given to you by a doctor or another healthcare professional as an intravenous infusion (into your vein).

TORISEL 30 mg concentrate must first be diluted with 1.8 ml of withdrawn diluent to achieve a concentration of 10 mg/ml before administration in sodium chloride 9 mg/ml (0.9%) solution for injection (see dilution instructions at the end of the package leaflet).

For renal cancer, the recommended dose is 25 mg infused (as a drip) over a 30- to 60-minute period once weekly.

For mantle cell lymphoma, the recommended dosing is 175 mg infused (as a drip) over a 30- to 60-minute period once weekly for 3 weeks followed by single weekly doses of 75 mg infused (as a drip) over a 30- to 60-minute period.

You should receive an injection of antihistamine (to try to prevent allergic reaction to TORISEL) directly into your vein approximately 30 minutes before your dose of TORISEL.

Treatment with TORISEL should continue until you are no longer benefiting from therapy or until unacceptable side effects occur.

If too much TORISEL is given or you miss a dose

As this medicine is prepared and given by a healthcare professional, it is unlikely you will be given too much.

If you are concerned about this, or think you may have missed a dose, tell your doctor immediately.

What are possible side effects?

Like all medicines, TORISEL can cause side effects, although not everybody gets them. Side effects may be more pronounced during the higher dose of 175 mg / week during initial treatment for mantle cell lymphoma.

For doctors

What is it?

Torisel is a concentrate and diluent that are made up into a solution for infusion (drip into a vein). It contains the active substance temsirolimus.

What is it used for?

Torisel is used to treat patients with the following types of cancer:
- advanced renal cell carcinoma (a type of kidney cancer). ‘Advanced’ means that the cancer has started to spread;
- mantle cell lymphoma (an aggressive cancer of a type of white blood cell called B-lymphocytes). Torisel is used in adults when the lymphoma has come back after previous treatment or has not responded to other treatments.
Because the numbers of patients with renal cell carcinoma and mantle cell lymphoma are low, the diseases are considered ‘rare’, and Torisel was designated an ‘orphan medicine’ (a medicine used in rare diseases) on 6 April 2006 (for renal cell carcinoma) and on 6 November 2006 (for mantle cell lymphoma).
The medicine can only be obtained with a prescription.

How is it used?

Torisel must be given under the supervision of a doctor who has experience in the use of anticancer medicines. For renal cell carcinoma, the recommended dose is 25 mg once a week, but a 10-mg dose is recommended in patients with severe liver problems who have high levels of platelets in the blood before treatment. For mantle cell lymphoma, the recommended dose is 175 mg once a week for three weeks, followed by weekly doses of 75 mg.
Torisel is given as an infusion lasting 30 to 60 minutes. Patients should receive an antihistamine to prevent an allergic reaction around 30 minutes before each dose of Torisel. Treatment with Torisel should continue until the patient does not benefit from the medicine any more or has unacceptable side effects. Some side effects can be managed by interrupting treatment or reducing the dose.

How does it work?

The active substance in Torisel, temsirolimus, is an anticancer medicine, which acts by blocking a protein called ‘mammalian target of rapamycin’ (mTOR). In the body, temsirolimus attaches to a protein that is found inside cells to make a ‘complex’. This complex then blocks mTOR. Since mTOR is involved in the control of cell division, Torisel prevents the division of cancer cells, slowing down the growth and spread of the cancer.

How has it been studied?

In advanced renal cell carcinoma, Torisel has been studied in one main study involving 626 patients who had a poor prognosis. The study compared 25 mg Torisel with interferon alfa (another anticancer medicine) and with 15 mg Torisel in combination with interferon alfa. The main measure of effectiveness was how long the patients survived. In mantle cell lymphoma, Torisel has been studied in 162 patients whose disease had come back after previous treatment or had not responded to other treatments. Each patient received one of two doses of Torisel or the most appropriate alternative treatment chosen by the investigator from a list of medicines commonly used to treat this type of cancer such as gemcitabine or fludarabine. The main measure of effectiveness was how long the patients lived without the disease getting worse.

What benefits has it shown during the studies?

Torisel was more effective than the comparator treatments. In advanced renal cell carcinoma, patients receiving Torisel alone survived for an average of 10.9 months, compared with 7.3 months in those receiving interferon alfa alone. The patients receiving the lower dose of Torisel in combination with interferon alfa survived for a similar length of time (8.4 months) as those taking interferon alfa alone. In mantle cell lymphoma, patients receiving the approved dose of Torisel lived for an average of 4.8 months without their disease getting worse, compared with 1.9 months in those receiving the alternative treatment.

What is the risk associated?

The most common side effects with Torisel (seen in more than 1 patient in 10) are bacterial and viral infections, pneumonia (infection of the lungs), urinary tract infections (infections of the structures that carry urine), pharyngitis (sore throat), upper respiratory tract infection (colds), rhinitis (stuffy and runny nose), thrombocytopenia (low blood platelet counts), anaemia (low red blood cell counts), neutropenia (low levels of neutrophils, a type of white blood cell), leucopenia (low white blood cell counts), lymphopenia (low levels of lymphocytes, a type of white blood cell), hypokalaemia (low blood potassium levels), loss of appetite, hyperglycaemia (high blood sugar levels), diabetes, hypercholesterolaemia (high blood cholesterol levels), hyperlipaemia (high blood fat levels), insomnia (difficulty sleeping), anxiety, dysgeusia (taste disturbances), dyspnoea (difficulty breathing), epistaxis (nose bleeds), cough, abdominal pain (stomach ache), vomiting, stomatitis (inflammation of the lining of the mouth), diarrhoea, nausea (feeling sick), rash, pruritus (itching), acne (spots), nail disorders, dry skin, back pain, arthralgia (joint pain), myalgia (muscle pain), oedema (swelling), asthenia (weakness), pain, pyrexia (fever), mucositis (inflammation of the moist body surfaces), chest pain, chills and increased blood creatinine levels (a marker of kidney problems). For the full list of all side effects reported with Torisel, see the Package Leaflet.
Torisel should not be used in people who may be hypersensitive (allergic) to temsirolimus, to its metabolites (the substances that it is broken down into) including sirolimus (a medicine used to prevent rejection of transplanted kidneys), to polysorbate 80 or to any of the other ingredients of the medicine. Torisel is not recommended for patients with mantle cell lymphoma who have moderate or severe problems with their liver.

Why has it been approved?

The Committee for Medicinal Products for Human Use (CHMP) decided that Torisel’s benefits are greater than its risks and recommended that it be given marketing authorisation.

Further information

The European Commission granted a marketing authorisation valid throughout the European Union for Torisel to Wyeth Europa Ltd on 19 November 2007. The marketing authorisation is valid for five years, after which it can be renewed.
