Special populations

Renal impairment
Studies in renally impaired patients have not been conducted. As thiotepa and its metabolites are poorly excreted in the urine, dose modification is not recommended in patients with mild or moderate renal insufficiency. However, caution is recommended (see sections 4.4 and 5.2 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Hepatic impairment
Thiotepa has not been studied in patients with hepatic impairment. Since thiotepa is mainly metabolised through the liver, caution needs to be exercised when thiotepa is used in patients with pre-existing impairment of liver function, especially in those with severe hepatic impairment. Dose modification is not recommended for transient alterations of hepatic parameters (see section 4.4 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Elderly
The administration of thiotepa has not been specifically investigated in elderly patients. However, in clinical studies, a proportion of patients over the age of 65 received the same cumulative dose as the other patients. No dose adjustment was deemed necessary.

Method of administration
Thiotepa Riemser is for intravenous use. It must be administered by a qualified healthcare professional as a 2 – 4 hours intravenous infusion via a central venous catheter.

Each vial of 15 mg thiotepa must be reconstituted with 1.5 mL of sterile water for injections.

Each vial of 100 mg thiotepa must be reconstituted with 10 mL of sterile water for injections.

The total volume of reconstituted vials to be administered should be further diluted in 500 mL of sodium chloride 9 mg/mL (0.9%) solution for injection prior to administration (1 000 mL if the dose is higher than 500 mg). In paediatric patients, if the dose is lower than 250 mg, an appropriate volume of sodium chloride 9 mg/mL (0.9%) solution for injection may be used in order to obtain a final Thiotepa Riemser concentration between 0.5 and 1 mg/mL. For instructions on reconstitution and further dilution prior to administration, see section 6.6– please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information.

Precautions to be taken before handling or administering the medicinal product
Topical reactions associated with accidental exposure to thiotepa may occur. Therefore, the use of gloves is recommended in preparing the solution for infusion. If thiotepa solution accidentally contacts the skin, the skin must be immediately thoroughly washed with soap and water. If thiotepa accidentally contacts mucous membranes, they must be flushed thoroughly with water (see section 6.6 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

4.3 Contraindications

Pregnancy and lactation (see section 4.6 – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).
