Other information about Cabometyx
Druge informacije o zdravilu Cabometyx
Why is Cabometyx authorised in the EU?
Zakaj je zdravilo Cabometyx odobreno v EU?
It is used in patients who have been previously treated with a type of cancer medicine called ‘vascular endothelial growth factor (VEGF) inhibitor'.
Uporablja se pri bolnikih, ki so se predhodno zdravili z vrsto zdravila za zdravljenje raka, ki se imenuje „zaviralec endotelijskega rastnega faktorja v žilah (VEGF)“.
By blocking the activity of these enzymes in cancer cells, the medicine reduces the growth and spread of the cancer.
Zdravilo z zaviranjem delovanja teh encimov v rakavih celicah zmanjša rast in širjenje raka.
For more information about using Cabometyx, see the package leaflet or contact your doctor or pharmacist.
Za več informacij glede uporabe zdravila Cabometyx glejte navodilo za uporabo ali se posvetujte z zdravnikom ali farmacevtom.
These enzymes can be found in certain receptors in cancer cells, where they are involved in activating processes that include cell division and the growth of new blood vessels to supply the cancer.
Ti encimi so prisotni v nekaterih receptorjih v rakavih celicah, v katerih spodbujajo procese, ki vključujejo delitev celic in rast novih žil, ki oskrbujejo raka.
The most common serious side effects (seen in more than 1 person in 100) with Cabometyx in patients with renal cell carcinoma are high blood pressure, diarrhoea, nausea (feeling sick), loss of appetite, tiredness, dehydration, hyponatraemia and hypomagnesaemia (low blood levels of sodium and magnesium), palmar-plantar erythrodysaesthesia syndrome (hand-foot syndrome, which involves rash and numbness on the palms and soles) and embolism (clot in a blood vessel).
Najpogostejši resni neželeni učinki (opaženi pri več kot 1 osebi od 100) zdravila Cabometyx pri bolnikih s karcinomom ledvičnih celic so visoki krvni tlak, driska, navzeja (slabost), izguba teka, utrujenost, dehidracija, hiponatriemija in hipomagneziemija (nizka raven natrija in magnezija v krvi), sindrom palmarno-plantarne eritrodisestezije (sindrom roka-noga, ki vključuje izpuščaje in odrevenelost dlani in podplatov) ter embolija (strdek v krvnih žilah).
An overview of Cabometyx and why it is authorised in the EU
Pregled zdravila Cabometyx in zakaj je odobreno v EU
In previously untreated patients with moderate or high risk disease, Cabometyx also provided clinically relevant benefit, delaying the progression of the cancer and the need for other treatments.
Pri predhodno nezdravljenih bolnikih z boleznijo z zmernim ali visokim tveganjem je zdravilo Cabometyx omogočilo tudi klinično pomembno korist, saj je upočasnilo napredovanja raka in odložilo potrebo po drugih zdravilih.
It is also used in patients who have not had previous treatment and whose cancer is at moderate or high risk of rapidly getting worse.
Uporablja se tudi pri bolnikih, ki se predhodno niso zdravili in pri katerih obstaja zmerno do visoko tveganje za hitro napredovanje raka.
This means that it blocks the activity of enzymes known as tyrosine kinases.
To pomeni, da zavira delovanje encimov, imenovanih tirozinkinaze.
The study involved 157 patients, and compared Cabometyx with another cancer medicine, sunitinib.
Študija je vključevala 157 bolnikov, v njej pa so primerjali zdravilo Cabometyx z drugim zdravilom za zdravljenje raka, sunitinibom.
A second main study showed that Cabometyx was effective in adults with previously untreated renal cell carcinoma that was locally advanced or had spread elsewhere in the body.
Druga glavna študija je pokazala, da je zdravilo Cabometyx učinkovito pri odraslih s predhodno nezdravljenim karcinomom ledvičnih celic, ki je napredoval lokalno ali se je razširil na druge dele telesa.
Side effects reported with Cabometyx are carefully evaluated and any necessary action taken to protect patients.
Neželeni učinki, o katerih so poročali pri zdravilu Cabometyx, se skrbno ovrednotijo in po potrebi se sprejmejo ukrepi za zaščito bolnikov.
What benefits of Cabometyx have been shown in studies?
Kakšne koristi je zdravilo Cabometyx izkazalo v študijah?
In addition, results indicated that patients treated with Cabometyx lived overall longer than patients treated with everolimus (an average of 21.4 months compared with 16.5 months).
Poleg tega so rezultati pokazali, da so bolniki, ki so se zdravili z zdravilom Cabometyx, na splošno živeli dlje kot bolniki, ki so se zdravili z everolimusom (v povprečju 21,4 meseca v primerjavi s 16,5 meseca).
What are the risks associated with Cabometyx?
Kakšna tveganja so povezana z zdravilom Cabometyx?
Cabometyx can only be obtained with a prescription and treatment should be started by a doctor who has experience of using cancer medicines.
Predpisovanje in izdaja zdravila Cabometyx je le na recept, zdravljenje z njim pa sme uvesti le zdravnik, ki ima izkušnje z uporabo zdravil za zdravljenje raka.
What is Cabometyx and what is it used for?
Kaj je zdravilo Cabometyx in za kaj se uporablja?
Results also indicated that Cabometyx helped patients to live longer.
Rezultati so pokazali tudi, da je zdravilo Cabometyx bolnikom pripomoglo k podaljšanju preživetja.
Treatment is continued for as long as the patient benefits from it or until side effects become unacceptable.
Zdravljenje je treba nadaljevati, dokler je za bolnika koristno, oziroma do pojava nesprejemljivih neželenih učinkov.
The most common serious side effects (seen in more than 1 person in 100) with Cabometyx in patients with hepatocellular carcinoma are hepatic encephalopathy (harmful effects on the brain caused by liver damage), palmar-plantar erythrodysaesthesia syndrome, weakness and diarrhoea.
Najpogostejši resni neželeni učinki (opaženi pri več kot 1 osebi od 100) zdravila Cabometyx pri bolnikih s hepatocelularnim karcinomom so jetrna encefalopatija (škodljivi učinki na možgane, ki jih povzroča poškodba jeter), sindrom palmarno-plantarne eritrodisestezije, šibkost in driska.
The side effects of Cabometyx are similar to other tyrosine kinase inhibitors, and they are considered manageable.
Neželeni učinki zdravila Cabometyx so podobni tistim pri drugih zaviralcih tirozinkinaze in veljajo za obvladljive.
The active substance in Cabometyx, cabozantinib, is a ‘tyrosine kinase inhibitor'.
Zdravilna učinkovina v zdravilu Cabometyx, kabozantinib, je „zaviralec tirozin-kinaze“.
For the full list of side effects and restrictions with Cabometyx, see the package leaflet.

Cabometyx is a cancer medicine used to treat adults with:
Zdravilo Cabometyx se uporablja za zdravljenje raka pri odraslih bolnikih:
Patients should not eat for at least two hours before and one hour after taking Cabometyx.
Priporočeni odmerek je 60 mg enkrat na dan. Bolniki ne smejo uživati hrane vsaj dve uri, preden vzamejo zdravilo Cabometyx, in eno uro po tem.
One main study involving 658 adults with advanced renal cell carcinoma that had got worse despite treatment with a VEGF inhibitor showed that Cabometyx is effective at prolonging the time patients lived without their disease getting worse (progression-free survival).
Ena glavna študija, ki je vključevala 658 odraslih z napredovalim karcinomom ledvičnih celic, ki se je poslabšal kljub zdravljenju z zaviralcem VEGF, je pokazala, da je zdravilo Cabometyx učinkovito pri podaljševanju obdobja preživetja bolnikov brez poslabšanja bolezni (preživetje brez napredovanja bolezni).
One main study involving 707 adults with hepatocellular carcinoma who had already been treated with sorafenib showed that Cabometyx was effective at prolonging how long patients lived (overall survival).
V eni glavni študiji, v katero je bilo vključenih 707 odraslih s hepatocelularnim karcinomom, ki so ga že zdravili s sorafenibom, je bilo ugotovljeno, da zdravilo Cabometyx učinkovito podaljšuje čas preživetja bolnikov (celokupno preživetje).
In the study, Cabometyx was compared with placebo (a dummy treatment).
V študiji so zdravilo Cabometyx primerjali s placebom (zdravilom brez učinkovine).
In the study, Cabometyx was compared with the cancer medicine everolimus.

Whereas
stopnje.
• The Committee considered the referral under Article 31 of Directive 2001/83/EC, as amended, for dexrazoxane-containing medicinal products;
• Odbor je obravnaval napotitev v skladu s členom 31 Direktive 2001/83/ES, kakor je bila spremenjena, za zdravila, ki vsebujejo deksrazoksan.
The majority of studies in adults have been conducted in breast cancer patients.
Večino študij pri odraslih so opravili pri bolnikih z rakom dojke.
The CHMP considered that a direct healthcare professional communication should be sent in order to inform adequately on the changes recommended.
CHMP je menil, da je treba poslati neposredno obvestilo za zdravstvene delavce, da bodo ustrezno obveščeni o priporočenih spremembah.
Based on the limited data on efficacy in this patient population, and the observed safety concerns, the Committee recommended that the use in children and adolescents up to 18 years of age should be contraindicated.
Na podlagi omejene količine podatkov o učinkovitosti v tej populaciji bolnikov in ugotovljenih varnostnih zadržkov je Odbor priporočil kontraindiciranje uporabe pri otrocih in mladostnikih do 18. leta.
In addition, a signal of increased risk of solid tumours was noted.
Poleg tega so ugotovili znake povečanega tveganja čvrstih tumorjev.
Overall summary of the scientific evaluation of dexrazoxane-containing medicinal products (see Annex I)
Splošni povzetek znanstvenega vrednotenja zdravil, ki vsebujejo deksrazoksan (glejte Dodatek I)
Sub-analysis of these studies also showed a significant reduction of congestive heart failure (CHF) events and a reduction in the severity of CHF events.
Podanalize teh študij so pokazale tudi bistveno zmanjšanje dogodkov kongestivnega srčnega popuščanja (CHF) in zmanjšanje resnosti teh dogodkov.
• The Committee also recommended that the ratio of dexrazoxane to doxorubicin should be reduced to take due account of the safety risks observed, including myelosuppression;
• Odbor je tudi priporočil, naj se zmanjša razmerje med deksrazoksanom in doksorubicinom, da se upoštevajo ugotovljena varnostna tveganja, vključno z mielosupresijo.
• The Committee considered that use of dexrazoxane in children and adolescents up to 18 years of age is associated with second primary malignancies and should therefore be contraindicated;
• Odbor je menil, da je uporaba deksrazoksana pri otrocih in mladostnikih, mlajših od 18 let, povezana z drugimi primarnimi malignimi tvorbami, zato jo je treba kontraindicirati.
• The Committee took into account all available data, including the responses from the MAHs and the conclusion of the SAG Oncology;
• Odbor je upošteval vse razpoložljive podatke, vključno z odgovori imetnikov dovoljenja za promet z zdravili ter zaključkom znanstveno-svetovalne skupine za onkologijo.
• The Committee recommended conditions to the marketing authorisation, including a direct healthcare professional communication, the shortening of the PSUR submission cycle to an annual submission and the monitoring of the effectiveness of the risk minimisation measures by means of a drug utilisation study.
• Odbor je priporočil pogoje dovoljenja za promet, vključno z neposrednim obvestilom za zdravstvene delavce, skrajšanjem cikla predložitve PSUR na letno oddajo ter spremljanje učinkovitosti ukrepov za zmanjševanje tveganja v obliki študije o uporabi zdravila.
Dexrazoxane is authorised in Europe through mutual recognition (MR), decentralised and national procedures for the prevention of anthracycline (doxorubicin or epirubicin)-induced cardiotoxicity.
Deksrazoksan je v Evropi odobren po postopkih z medsebojnim priznavanjem, decentraliziranih in nacionalnih postopkih za preprečevanje kardiotoksičnosti, povzročene z antraciklini (doksorubicinom ali epirubicinom).
As additional risk minimisation measures, the PSUR submission cycle will be shortened to an annual submission and the monitoring of the effectiveness of the risk minimisation measures will be conducted through a drug utilisation study.
V okviru dodatnih ukrepov za zmanjševanje tveganja se bo cikel predložitve PSUR skrajšal na letno oddajo, spremljanje učinkovitosti ukrepov za zmanjševanje tveganja pa se bo izvedlo v obliki študije o uporabi zdravila.
In addition to serious infections, other important potential safety risks include a higher incidence of death observed in some studies in groups treated with dexrazoxane plus chemotherapy compared to those treated with chemotherapy alone, and evidence of possible interference with anthracycline efficacy.
Poleg resnih okužb so druga pomembna morebitna varnostna tveganja večja pojavnost smrtnih primerov v določenih študijah v skupinah, zdravljenih s kombinacijo deksrazoksana in kemoterapije, v primerjavi z bolniki, zdravljenimi samo s kemoterapijo, in dokaz morebitne interference z učinkovitostjo antraciklina.
This was also the view of the SAG Oncology and the CHMP therefore recommended that the ratio of dexrazoxane to doxorubicin should be reduced from 20:1 to 10:1.
S tem se je strinjala znanstveno-svetovalna skupina za onkologijo, zato je CHMP priporočil zmanjšanje razmerja med deksrazoksanom in doksorubicinom iz 20 : 1 na 10 : 1.
The CHMP further advised that dexrazoxane should not be used in combination with adjuvant breast cancer therapy or chemotherapy intended as curative.
CHMP je dodatno opozoril, da se deksrazoksan ne sme uporabljati v kombinaciji z adjuvantnim zdravljenjem raka dojke ali kemoterapijo z namenom zdravljenja.
Following the consultation of the Scientific Advisory Group (SAG) on oncology, the CHMP agreed that the therapeutic indication should be restricted to adult breast cancer patients who had received a prior cumulative dose of 300 mg/m2 of doxorubicin or a prior cumulative dose of 540 mg/m2 of epirubicin when further anthracycline treatment is required.
Po posvetovanju z znanstveno-svetovalno skupino (SAG) za onkologijo se je CHMP strinjal, da je treba terapevtske indikacije omejiti na odrasle bolnike z rakom dojke, ki so predhodno prejeli kumulativni odmerek doksorubicina 300 mg/m2 ali kumulativni odmerek epirubicina 540 mg/m2 in potrebujejo dodatno zdravljenje z antraciklini.
In addition, considering the observed risks, including myelosuppression and excess early mortality reported in placebo-controlled US studies employing a dexrazoxane:doxorubicin dose ratio of 20:1, the CHMP considered that a reduction in the dexrazoxane dose is expected to have a favourable effect on dose-related safety issues.
Poleg tega je CHMP ob upoštevanju ugotovljenega tveganja, vključno z mielosupresijo in čezmerno zgodnjo smrtnostjo, o katerih so poročali v ameriških s placebom nadzorovanih študijah z razmerjem odmerkov med deksrazoksanom in doksorubicinom 20 : 1, menil, da se pričakuje, da bo imelo zmanjšanje odmerka deksrazoksana ugoden učinek na vprašanja glede varnosti odmerka.
AML was also identified as an uncommonly reported adverse reaction.
Kot občasen neželeni učinek je bila ugotovljena tudi AML.
• The Committee considered that the benefit-risk balance of dexrazoxane for the prevention of anthracycline (doxorubicin and epirubicin)-induced cardiotoxicity remains favourable in adult patients with advanced and/or metastatic breast cancer who have received a minimum prior cumulative dose of anthracyclines; therefore the CHMP recommended a restriction of the indication accordingly.
• Odbor je menil, da razmerje med tveganji in koristmi deksrazoksana za preprečevanje kardiotoksičnosti, povzročene z antraciklini (doksrubicinom in epirubicinom), ostaja pozitivno pri odraslih bolnikih z napredovalim in/ali metastatskim rakom dojke, ki so že prejeli najmanjši kumulativni odmerek antraciklinov, zato je priporočil ustrezno omejitev indikacije.
The dose ratio of dexrazoxane to epirubicin remained unchanged at 10:1.
Razmerje odmerkov med deksrazoksanom in epirubicinom je ostalo nespremenjeno, tj. 10 : 1.
In addition there were concerns regarding the potential carcinogenic/leukaemogenic risk of dexrazoxane, which is a known cytotoxic agent with topoisomerase II inhibition activity.
Poleg tega so se pojavili zadržki glede morebitnega tveganja kancerogenega/levkemogenega delovanja deksrazoksana, ki je znano citotoksično sredstvo, ki zavira topoizomerazo II.
SCIENTIFIC CONCLUSIONS AND GROUNDS FOR AMENDMENT OF THE SUMMARY OF PRODUCT CHARACTERISTICS AND PACKAGE LEAFLET PRESENTED BY THE EMA
ZNANSTVENI ZAKLJUČKI IN PODLAGA ZA DOPOLNILO POVZETKA GLAVNIH ZNAČILNOSTI ZDRAVILA IN NAVODILA ZA UPORABO, KI JIH JE PREDSTAVILA EVROPSKA AGENCIJA ZA ZDRAVILA
Dexrazoxane is indicated in combination with anthracycline chemotherapy, and the risk of myelosuppressive effects may be additive to those of chemotherapy, which increases the risk of developing serious infections.
Deksrazoksan je indiciran v kombinaciji z antraciklinsko kemoterapijo, tveganje mielosupresivnih učinkov pa lahko prispeva k učinkom kemoterapije, kar poveča tveganje pojava resnih okužb.
