WHAT ROTOP - EHIDA IS AND WHAT IT IS USED FOR Kit for radiopharmaceutical preparation. Powder for preparation of a [ 99m Tc]technetium etifenin injection solution. After radiolabelling with the sodium [ 99m Tc]pertechnetate injection solu- tion, etifenin forms the diagnostic radiopharmaceutical [ 99m Tc]technetium etifenin injection solution ([ 99m Tc]EHIDA). [ 99m Tc]EHIDA is used for hepatobiliary function scintigraphy where there is the following suspicion: - Acute cholecystitis - Chronic gall duct changes - Occlusion of ductus choledochus - Congenital aberrances of the gall duct system such as atresia - Provision of evidence of bile leak - For differential diagnosis of intrahepatic growth (suspicion of focal nodular hyperplasia versus suspicion of liver cell cancer). The diagnostic significance in liver cancer is rather marginal compared to other imaging procedures. 2. BEFORE YOU USE ROTOP - EHIDA Take special care with ROTOP - EHIDA The patient must be well hydrated before and after administration. In order to keep radiation exposure to a minimum, patients must be en- couraged to empty their bladders as often as possible during the first hours after the examination. For each patient it should be carefully considered whether the expected diagnostic benefits outweigh the risk linked to radiation exposure. In order to keep the radiation dose as low as possible, the administered activity may not be higher than that required for eliciting the diagnostic information. Radiopharmaceuticals may be received, used and administered only by authorised persons in areas specially designated for this purpose. The manipulation and use of these products is subject to the regulations of the local supervisory authority and/or requires appropriate permission. Using other medicines Opiates and pentobarbital will cause delayed excretion from the intestine, while choleretica such as cholecystokinin will accelerate this process. High doses of nicotinic acid lead to a reduced intake in the hepatocytes as a consequence of a toxic effect. Bethanechol, a parasympathometic drug belonging to the group of choline esters, leads to increased biliary excretion. Morphine and meta- done lead to an abnormal time required for transport in the duodenum. Paracetamol may cause filling defects in the liver due to hepatotoxicity. Mere parenteral nutrition can lead to missing or delayed entry into the gall bladder or a delayed transport of the tracer in the duodenum. To avoid detrimental effects on the stability of [ 99m Tc]EHIDA, the latter must not be mixed or administered concomitantly with other medicinal prod- ucts or components. Pregnancy and lactation Pregnancy: No data on the clinical use of etifenin with pregnant women is available. If it is necessary to administer a radiopharmaceutical product to a woman of child-bearing age, she must have a pregnancy test first. If a woman has missed a period, it must be assumed that she is preg- nant. In case of doubt, radiation exposure must be reduced to the min- imum amount required to acquire the needed clinical information. In this case, alternative investigative methods must be considered that do not use ionising radiation. Radiopharmaceutical examinations of pregnant women also expose the foetus to radiation. The administration of 150 MBq with normal or 420 MBq with disturbed liver function results in an absorbed dose of 1.6 mGy / 4.6 mGy in the uterus. Radiation doses above 0.5 mGy are considered as a potential hazard for the fetus. For this reason, [ 99m Tc]EHIDA may only be used during pregnancy if there is a vital indication and if the ex- pected benefit outweighs the risk to mother and child. [ 99m Tc]EHIDA passes into breast milk. Lactation: Before administering [ 99m Tc]EHIDA to a breast-feeding mother, it must be considered whether the investigation could also be delayed until the mother has ceased breast-feeding and as to whether using a radiopharmaceutical is the most appropriate examination method, bear- ing in mind the secretion of activity into breast milk. If administering ROTOP - EHIDA is deemed necessary, breast-feeding must be inter- rupted for at least 12 hours, and the expressed breast milk discarded. Driving and using machines Effects on the ability to drive and use machines have not been described. 3. HOW TO USE ROTOP - EHIDA? Single intravenous injection after reconstitution with sodium [ 99m Tc]per- technetate solution. Adults with a normal liver function will receive an activity of 150 MBq and up to 420 MBq if they have a disturbed liver function with serum bilirubin values >25 mol/l. Patients should not eat during at least 2 hours or better 4 hours prior to administration. Fasting for 24 or more hours and par- enteral nutrition can cause false positive results. Scintigraphy will start with the injection. The acquisition of late images may be indicated: - After 3 to 4 hours in cases of suspected acute cholecystitis where the gall bladder is not visible within 40 to 60 min. and for the purpose of finding a bile leak; - After 18 to 24 hours, in certain cases, in the event of heavy sickness, choledochus occlusion or biliary atresia. Children In children, [ 99m Tc]technetium etifenin is used without carrying out formal investigations. Clinical experience indicates that the activity should be reduced. The recommendation of the Paediatric Task Group of the Eu- ropean Association of Nuclear Medicine (EANM) of 1990 lists the paedi- atric dose scaled to body weight as a fraction of the adult dose: Activity for children as a fraction of adult activity (EANM Paediatric Task Group, 1990, and BfS, publication of 10 July 2003, Federal Gazette no. 143 of 5 August 2003, pg. 17503 - 17504) 3 kg = 0.1 22 kg = 0.50 42 kg = 0.78 4 kg = 0.14 24 kg = 0.53 44 kg = 0.80 6 kg = 0.19 26 kg = 0.56 46 kg = 0.82 8 kg = 0.23 28 kg = 0.58 48 kg = 0.85 10 kg = 0.27 30 kg = 0.62 50 kg = 0.88 12 kg = 0.32 32 kg = 0.65 52 - 54 kg = 0.90 14 kg = 0.36 34 kg = 0.68 56 - 58 kg = 0.92 16 kg = 0.40 36 kg = 0.71 60 - 62 kg = 0.96 18 kg = 0.44 38 kg = 0.73 64 - 66 kg = 0.98 20 kg = 0.46 40 kg = 0.76 68 kg = 0.99 Activity of less than 10% of the adult dose generally does not allow a satisfactory assessment to be derived from the examination. If you got more ROTOP - EHIDA than you should Due to the low amounts of substances used, overdosage in the phar- macological sense is not expected. Exposure to radiation resulting from an overdosage of radioactivity can be reduced by administration of lax- atives. Precautions for avoiding hazards for the environment Radiopharmaceuticals must be prepared and used by the user under precautions for the protection from ionising radiation and taking phar- maceutical quality standards into account. In accordance with the guide- lines for Good Pharmaceutical Manufacturing Practice, work must be done under aseptic conditions. Patients treated with radiopharmaceuticals pose a risk for other persons based on external radiation exposure or contamination due to spilling urine, vomiting, etc. For this reason, the precautionary measures pro- vided by the national radiation protection regulations must be observed. Contamination brought about by radioactivity that has been excreted by the patient must be avoided. 4. POSSIBLE SIDE EFFECTS As all medicinal products, ROTOP - EHIDA can cause side effects, al- though not everybody gets them. For assessing the side effects the frequency is classified as follows: Very common: observed in more than 1 patient in 10 Common: observed in less than 1 patient in 10, but more than 1 patient in 100 Uncommon: observed in less than 1 patient in 100, but more than 1 patient in 1,000 Rare: observed in less than 1 patient in 1,000, but more than 1 patient in 10,000 Very rare: observed in less than 1 patient in 10,000 or not known No information on adverse reactions after intravenous injection of the ready-to-use solution is available. For related substances such as diso- fenin and mebrofenin, hypersensitivity reactions such as flu-like symp- toms, nausea or pruritus have been reported in individual cases. Al- though such reactions are very rare and usually very minor, appropriate instruments and medications for immediate treatment of allergic reac- tions (adrenaline, corticosteroids and antihistamines) should be within reach for possible emergency treatment at all times. Since the adminis- tered amounts of active substances are very low, the risks of use are mainly related to radiation exposure. Ionising radiation can cause cancer and genetic mutations. Since most radiopharmaceutical examinations are conducted with low effective ra- diation doses of less than 20 mSv, the probability of such effects occur- ring is expected to be low. The effective radiation dose is 7.1 mSv when the maximum recommended activity of this medicinal product is applied. Reporting of side effects If you notice any side effects please contact your nuclear physician res- ponsible for supervising the administration. This also applies to any side effects not listed in this leaflet. You can also report any side effects directly to: Bundesinstitut für Arzneimittel und Medizinprodukte, Abt. Pharmakovigilanz, Kurt-Georg- Kiesinger Allee 3, D-53175 Bonn, website: http://www.bfarm.de. By reporting side effects you can help provide more information on the safety of this medicine. 5. HOW TO STORE ROTOP - EHIDA Keep out of the reach and sight of children. Do not use this medicinal product after the expiry date stated on the label. Storage conditions Store refrigerated (2 to 8 °C) in the original package. Radiopharmaceu- ticals must be stored in accordance with the regulations for radioactive protection and in particular be kept from unauthorised access. Shelf life after radiolabelling The product labelled with [ 99m Tc]technetium can be injected within 3 hours after preparation and during this period can be stored at room temperature (15 to 25°C). 6.

The following information is intended for medical or healthcare profes- sionals only: PHARMACOLOGICAL PROPERTIES Pharmacodynamic properties Pharmacotherapeutic group: Diagnostic radiopharmaceutical for the liver function (ATC: V09DA02). Based on current research, for the low amounts of substances used for imaging techniques no clinically relevant pharmacodynamic effects of [ 99m Tc]EHIDA are expected. Pharmacokinetic properties Etifenin crosses the placenta. After intravenous injection, [ 99m Tc]EHIDA is quickly bound to plasma proteins, taken up in the polygonal cells of the liver and excreted via the bile. Depending on the type of excretion, radioactivity is either temporarily stored in the gall bladder or directly ex- creted from the hepatobiliary system into the small intestine without prior accumulation. Through active transport, [ 99m Tc]EHIDA is taken up in the hepatocytes in a similar way as bilirubin and reaches the peak activity in the liver after 12 min. The liver half-life is 25 to 30 min. in healthy individuals, but can be influ- enced by the plasma albumin concentration, hepatic blood flow and he- patocytes function. If there is no significant bile congestion, only small quantities are delivered in the urine. In healthy patients, the biliary tree is visualised within 5 to 20 min. after injection, and the gall bladder within 10 to 40 min.. Toxicological properties No studies on acute toxicity of [ 99m Tc]EHIDA are available. However, on account of the low amount administered of etifenin (max. 0.3 mg per kg of body weight) and of tin(II)chloride (max. 0.01 mg per kg of body weight), no acute toxic effects must be expected. No studies are available on the toxicity after repeated use, reproductive toxicity or mutagenic and carcinogenic effects. Special precautions for disposal and further directions for handling The empty package is considered to be regular waste if the permitted level for [ 99m Tc]technetium is not exceeded (0.5 Bq/g or 0.5 Bq/cm 2 ). This Package Leaflet and Summary of Product Characteristics was translated by the manufacturer based on the original German document (Vs. 07), authorized by the German Federal Institute for Drugs and Medicinal Services in November 2014.

Radiophysical properties

[99mTc]technetium is produced using a [99Mo/99mTc] sterile generator anddecays releasing gamma radiation with an energy of 140/142 keV witha half-life of 6.02 hours to [99Tc]technetium, which in turn decays to stable[99mRu]ruthenium; However, due to a long half-life of 214,000 years,[99mTc]technetium itself is considered to be stable.

INSTRUCTIONS FOR PREPARATION OF RADIOPHARMACEUTI-

CALS

Instructions for labelling

[99mTc]EHIDA is prepared under sterile conditions with a sodium[99mTc]pertechnetate injection solution (European Pharmacopoeia, 0125or 0283) directly before use. Oxygenation must be avoided.

Place the vial with powder in sufficient lead shielding with ample spaceand disinfect the stopper (allow disinfectant to dry).

Use a syringe with the smallest possible cannula lumen to transfer amaximum of 3 ml of sodium [99mTc]pertechnetate injection solution witha maximum of 8 GBq to the vial. Use the same syringe to withdraw theappropriate gas volume from the vial for pressure compensation.

Lightly shake the vial in order to completely dissolve the powder. Thestopper should be well moistened as well. After 30 minutes reaction time,measure the overall activity. If needed, the finished injection solution canbe diluted with sterile isotonic sodium chloride to a total volume of up to6 ml.

Quality control

The test for radiochemical purity of the [99mTc]technetium etifenin injectionsolution must be performed before administration to the patient and according to the European Pharmacopoeia or to one of the followingmethods:

Method 1:

Test for [99mTc]technetium in colloidal form
