For information concerning interactions associated with the use of Yttrium (90Y)-labelled medicinalproducts refer to the Summary of Product Characteristics/package leaflet of the medicinal product tobe radiolabelled.
4.6 Fertility, pregnancy and lactation
YTRACIS is contraindicated during established or suspected pregnancy or when pregnancy has notbeen excluded (see section 4.3 Contraindications).
When it is necessary to administer radioactive medicinal products to women of childbearing potential,information should always be sought about pregnancy. Any woman who has missed a period shouldbe assumed to be pregnant until proven otherwise. Alternative techniques which do not involveionising radiation should always be considered.
Radionuclide procedures carried out in pregnant women also involve radiation doses to the foetus.
The absorbed dose to the uterus following administration of Yttrium (90Y)-labelled medicinalproducts is dependent on the specific medicinal product being radiolabelled and is to be specified inthe Summary of Product Characteristics/ package leaflet of the medicinal product to be radiolabelled.
Before administering a radioactive medicinal product to a mother who is breast-feeding, considerationshould be given to whether the administration could be reasonably delayed until the mother hasceased breastfeeding. If the administration cannot be delayed, a lactating mother should be advised tostop breastfeeding.
For information concerning the use of Yttrium (90Y)-labelled medicinal products in pregnancy andlactation refer to the Summary of Product Characteristics/package leaflet of the medicinal product tobe radiolabelled.
4.7 Effects on ability to drive and use machines
No studies on the effects on the ability to drive and use machines have been performed.
Effects on ability to drive or use machines following treatment by Yttrium (90Y)-labelled medicinalproducts will be specified in the Summary of Product Characteristics/package leaflet of the particularmedicinal product to be radiolabelled.
4.8 Undesirable effects
Possible side effects following the intravenous administration of Yttrium (90Y)-labelled medicinalproducts prepared by radiolabelling with YTRACIS, will be dependent on the specific medicinalproduct being used. Such information will be supplied in the Summary of Product
Characteristics/package leaflet of the medicinal product to be radiolabelled. For each patient,exposure to ionising radiation must be justifiable on the basis of likely clinical benefit. The activityadministered must be such that the resulting radiation dose is as low as reasonably achievable bearingin mind the need to obtain the intended therapeutic result.
The radiation dose resulting from therapeutic exposure may result in higher incidence of cancer andmutations. In all cases, it is necessary to ensure that the risks of the radiation are less than from thedisease itself.
Exposure to ionising radiation is linked with cancer induction and a potential for development ofhereditary defects.
Reporting of suspected adverse reactionsReporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.
4.9 Overdose
The presence of free Yttrium (90Y) chloride in the body after an inadvertent administration of Ytraciswill lead to increase bone marrow toxicity and haematopoetic stem cell damage. Therefore, in case ofan inadvertent administration of Ytracis, the radiotoxicity for the patient must be reduced byimmediate (i.e. within 1 hour) administration of preparations containing chelators like Ca-DTPA or
Ca- EDTA in order to increase the elimination of the radionuclide from the body.
The following preparations must be available in medical institutions, which use Ytracis forradiolabelling of carrier molecules for therapeutic purposes:
Ca-DTPA (Trisodium calcium diethylenetriaminepentaacetate) or
Ca-EDTA (Calcium disodium ethylenediaminetetraacetate)
These chelating agents suppress yttrium radiotoxicity by an exchange between the calcium ion and theyttrium due to their capacity of forming water soluble complexes with the chelating ligands (DTPA,
EDTA). These complexes are rapidly eliminated by the kidneys.
1 g of the chelating agents should be administered by slow intravenous injection over3-4 minutes or by infusion (1 g in 100-250 ml of dextrose, or normal saline).
The chelating efficacy is greatest immediately or within one hour of exposure when the radionuclideis circulating in or available to tissue fluids and plasma. However, a post-exposure interval >1 hourdoes not preclude the administration and effective action of chelator with reduced efficiency.
Intravenous administration should not be protracted over more than 2 hours.
In any case the blood parameters of the patient have to be monitored and the appropriate actionsimmediately taken if there is evidence of damage to the blood marrow.
The toxicity of the free Yttrium (90Y) due to in-vivo release from the labelled biomolecule in the bodyduring therapy could be reduced by post-administration of chelating agents.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Not applicable
ATC code: Not applicable
Yttrium (90Y) chloride is produced by decay of its radioactive precursor Strontium (90Sr). It decays byemission of beta radiation of 2.281 MeV (99.98 %) of maximal energy to stable Zirconium (90Zr).90Y-yttrium has a half-life of 2.67 days (64.1 hours).
The pharmacodynamic properties of Yttrium (90Y)-labelled medicinal products prepared byradiolabelling with YTRACIS, prior to administration, will be dependent on the nature of themedicinal product to be radiolabelled. Refer to the Summary of Product Characteristics/packageleaflet of the particular medicinal product to be radiolabelled.
5.2 Pharmacokinetic properties
The pharmacokinetic properties of Yttrium (90Y)-labelled medicinal products prepared byradiolabelling with YTRACIS, prior to administration, will be dependent on the nature of themedicinal product to be radiolabelled.
In the rat, following intravenous administration, Yttrium (90Y) chloride is rapidly cleared from theblood. At 1 and 24 hours, blood radioactivity decreases from 11 % to 0.14 % of the administeredactivity. The two main organs where Yttrium (90Y) chloride distributes are the liver and bones. In theliver, 18 % of the injected activity is taken up 5 min after injection. Liver uptake decreases then to8.4 % 24 hours after injection. In bone, percentage of injected activity increases from 3.1 % at 5 minto 18 % at 6 hours and then decreases with time. Faecal and urinary elimination is slow: about 13 %of the administered activity is eliminated in 15 days.
5.3 Preclinical safety data
The toxicological properties of Yttrium (90Y)-labelled medicinal products prepared by radiolabellingwith YTRACIS prior to administration, will be dependent on the nature of the medicinal product to beradiolabelled.
There are no data available on the toxicity of Yttrium (90Y) chloride nor on its effects on reproductionin animals or its mutagenic or carcinogenic potential.
