- adult patients with newly diagnosed glioblastoma multiforme concomitantly with radiotherapy (RT) and subsequently as monotherapy treatment;

What is Temomedac?
Temomedac is a cancer medicine that contains the active substance temozolomide. It is available as capsules (5, 20, 100, 140, 180 and 250 mg).
Temomedac is a ‘generic medicine’. This means that Temomedac is similar to a ‘reference medicine’ already authorised in the European Union (EU) called Temodal.
What is Temomedac used for?
Temomedac is used to treat malignant glioma (brain tumours) in the following groups of patients:
- adults with newly diagnosed glioblastoma multiforme (an aggressive type of brain tumour). Temomedac is used first with radiotherapy and then on its own;
- adults and children three years of age and over with malignant glioma such as glioblastoma multiforme or anaplastic astrocytoma, when the tumour has returned or got worse after standard treatment. Temomedac is used on its own in these patients.
The medicine can only be obtained with a prescription.
How is Temomedac used?
Treatment with Temomedac should be prescribed by a doctor with experience in the treatment of brain tumours.
The dose of Temomedac depends on body surface area (calculated using the patient’s height and weight) and ranges from 75 to 200 mg per square metre, once a day. The dose and the number of doses depend on the type of tumour being treated, whether the patient has been treated before, whether Temomedac is being used alone or with other treatments, and how the patient responds to treatment.
Temomedac capsules should be taken whole without food. Patients may also need to take medicines to prevent vomiting before taking Temomedac.

How does Temomedac work?
The active substance in Temomedac, temozolomide, belongs to a group of cancer medicines called alkylating agents. In the body, temozolomide is converted to another compound called MTIC. MTIC binds to the DNA of cells while they are reproducing, which stops cell division. As a result, the cancer cells cannot divide, slowing down the growth of tumours.
How has Temomedac been studied?
Because Temomedac is a generic medicine, studies in people have been limited to tests to determine that it is bioequivalent to the reference medicine, Temodal. Two medicines are bioequivalent when they produce the same levels of the active substance in the body.
What are the benefit and risk of Temomedac?
Because Temomedac is a generic medicine and is bioequivalent to the reference medicine, its benefit and risk are taken as being the same as the reference medicine.
Why has Temomedac been approved?
The CHMP concluded that, in accordance with EU requirements, Temomedac has been shown to have comparable quality and to be bioequivalent to Temodal. Therefore, the CHMP’s view was that, as for Temodal, the benefit outweighs the identified risk. The Committee recommended that Temomedac be given marketing authorisation.
