CLINICAL PARTICULARS
4.1 Therapeutic indications
Epirubicin is used in the treatment of a range of neoplastic conditions including;
- Breast carcinoma
- Gastric carcinoma
When administered intravesically, epirubicin has been shown to be beneficial in the treatment of:
- Papillary transitional cell carcinoma of the bladder
- Carcinoma in-situ of the bladder
- Intravesical prophylaxis of recurrence of superficial bladder carcinoma following transurethral resection.
For intravesical use a positive benefit-risk ratio could only be established in patients in whom live attenuated BCG is contra-indicated or inappropriate.
Epirubicin can be used in polychemotherapy schedules.
4.2 Posology and method of administration
Epirubicin is only intended for intravenous or intravesical use.
Intravenous use
It is advisable that the red solution, which should be clear and transparent, is injected via the catheter of a free running intravenous infusion of NaCl 0,9 % (9 mg/ml) or glucose 5% (50 mg/ml) over a period of up to a duration of 30 minutes (depending on the dose and the volume of the infusion). The needle should be properly placed in the vein. This method reduces the risk of thrombosis and extravasation that could lead to severe cellulitis and necrosis. In case of extravasation, administration should be stopped immediately. Injection in small veins and repeated injection in the same vein can lead to venous sclerosis.
Conventional dose
If epirubicin is used as monotherapy, the recommended dose in adults is 60-90 mg/m2 of body surface area. Epirubicin should be injected intravenously over 3-5 minutes. The same dose is repeated with an interval of 21 days.
With the dosing schedule the haematolo-medullar state of the patient should be taken into account.
If signs of toxicity, including neutropenia/neutropenic fever and thrombocytopenia occur (which could persist at day 21), dose modification or postponement of the subsequent dose may be required.
High dose
Epirubicin as monotherapy for the treatment of breast carcinoma with a high dose should be administered in accordance to the following regimen:
For the treatment with a high dose epirubicin can be administered as an intravenous bolus over 3 - 5 minutes or as an infusion up to 30 minutes duration.
Breast carcinoma
In the adjuvant treatment of early breast cancer patients with positive lymph nodes intravenous doses of epirubicin going from 100 mg/m2 (as a single dose on day 1) to 120 mg/m2 (in two divided doses on days 1 and 8) every 3-4 weeks in combination with intravenous cyclophosphamide and 5-fluorouracil is recommended.
Lower dose (60-75 mg/m2 for usual treatment and 105 - 120 mg/m2 for treatment with high dose) or postponement of the next dose are recommended for patients with reduced bone marrow function due to prior chemotherapy or radiotherapy, due to age or neoplastic bone marrow infiltration. The complete dose per cycle can be distributed over 2 - 3 consecutive days.
The following doses of epirubicin are commonly used in monotherapy and combination therapy for various tumours, as shown:

* Doses generally given Day 1 or Day 1, 2 and 3 at 2l-day intervals
Combination chemotherapy
When Epirubicin is used in combination with other antitumoural products, the dose is reduced accordingly. Commonly used doses are shown in the table above.
Special patient groups
Elderly patients
It is recommended to reduce the dose in elderly patients.
Children
The safety and efficacy of epirubicin in children has not been established.
Impaired liver function
The excretion of epirubicin occurs primarily via the liver. In patients with a liver function disorder the dose should be reduced as follows, in order to avoid an increase of general toxicity:
|
Serum bilirubin |
AS T (aspartate aminotransferase) |
Dose reduction |
|
1.4 - 3 mg/100 ml |
2 - 4 times the normal upper limit |
Dose reduction of 50% |
|
> 3 mg/100 ml |
> 4 times the normal upper limit |
Dose reduction of 75% |
Impaired renal function
Moderate renal insufficiency is not a reason for dose reduction, considering the limited amount of epirubicin that is excreted via this route. However, in patients with severe renal insufficiency (serum creatinine> 450 pmol/l) a dose reduction is recommended.
Intravesical use
For instructions on dilution of the product before administration also see section 6.6.
Epirubicin can be administered by intravesical route for the treatment of superficial bladder carcinoma, carcinoma in situ and prophylactic to prevent recurrence after transurethral resection. It should not be administered by intravesical route for the treatment of invasive tumours that have penetrated the bladder wall, systemic therapy or surgery is more suitable in these situations.
Various dosing schedules are used. The following can be used as a guideline: Superficial bladder carcinoma: weekly bladder lavage with 50 mg/50 ml (diluted with NaCl or sterile water) for 8 weeks. A dose reduction of 30 mg per 50 ml is advised in case of local toxicity (chemical cystitis).
Carcinoma in situ: Up to 80 mg/50 ml (depending on the tolerability of the patient). Prophylaxis of recurrence after transurethral resection: 4 times a weekly administration of 50 mg/50 ml followed by 11 times a monthly instillation of the same dose.

4.4 Special warnings and precautions for use
General - Epirubicin should be administered only under the supervision of qualified physicians experienced in the use of cytotoxic therapy.
Epirubicin must not be administered subcutaneously or intramuscularly.
Initial treatment calls for careful baseline monitoring of various laboratory parameters and cardiac function.
If epirubicin is administered as a continuous infusion, this should preferably take place via a central venous catheter.
Patients should recover from acute toxicities (such as stomatitis, mucositis, neutropenia, thrombocytopenia, and generalized infections) of prior cytotoxic treatment before beginning treatment with epirubicin.
While treatment with high doses of epirubicin (e g. > 90 mg/m2 every 3 to 4 weeks) causes adverse events generally similar to those seen at standard doses (< 90 mg/m2 every 3 to 4 weeks), the severity of the neutropenia and stomatitis/mucositis may be increased. Treatment with high doses of epirubicin does require special attention for possible clinical complications due to profound myelosuppression.
Cardiac Function - Cardiotoxicity is a risk of anthracycline treatment that may be manifested by early (i.e., acute) or late (i.e., delayed) events.
It involves a permanent reduction of the QRS-voltage, a prolongation outside the normal limits of the systolic time interval (PEP/LVET) and a reduction of the left ventricular ejection fraction. Early clinical diagnosis of heart failure induced by cytostatic agents appears essential to a successful treatment with digitalis, diuretics, peripheral vasodilators, a diet with a low sodium content and sufficient bed rest. Therefore, cardiac monitoring of patients receiving epirubicin treatment is highly important and it is advisable to assess cardiac function by non-invasive techniques.
Early (i.e., Acute) Events. Early cardiotoxicity of epirubicin consists mainly of sinus tachycardia and/or electrocardiogram (ECG) abnormalities such as non-specific ST-T wave changes. Tachyarrhythmias, including premature ventricular contractions, ventricular tachycardia, and bradycardia, as well as atrioventricular and bundlebranch block have also been reported. These effects do not usually predict subsequent development of delayed cardiotoxicity, are rarely of clinical importance, and are generally not a consideration for the discontinuation of epirubicin treatment.
Late (i.e., Delayed) Events. Delayed cardiotoxicity usually develops late in the course of therapy with epirubicin or within 2 to 3 months after treatment termination, but later events (several months to years after completion of treatment) have also been reported. Delayed cardiomyopathy is manifested by reduced left ventricular ejection fraction (L VEF) and/or signs and symptoms of congestive heart failure (CHF) such as dyspnea, pulmonary edema, dependent edema, cardiomegaly and hepatomegaly, oliguria, ascites, pleural effusion, and gallop rhythm. Life-threatening CHF is the most severe form of anthracycline-induced cardiomyopathy and represents the cumulative dose-limiting toxicity of the drug.
The risk of developing CHF increases rapidly with increasing total cumulative doses of epirubicin in excess of 900 mg/m2 or a lower cumulative dose in patients who received radiation of the mediastenal area; this cumulative dose should only be exceeded with extreme caution (see section 5.1).
Cardiac function should be assessed before patients undergo treatment with epirubicin and must be monitored (by means of an ECG, echocardiography or nuclear measuring of the ejection fraction (by means of a radionuclide angiography)) throughout therapy to minimize the risk of incurring severe cardiac impairment. The risk may be decreased through regular monitoring of L VEF during the course of treatment with prompt discontinuation of epirubicin at the first sign of impaired function. The appropriate quantitative method for repeated assessment of cardiac function (evaluation of L VEF) includes multi-gated radionuclide angiography (MUG A) or echocardiography (ECHO). A baseline cardiac evaluation with an ECG and either a MUGA scan or an ECHO is recommended, especially in patients with risk factors for increased cardiotoxicity. Repeated MUGA or ECHO determinations of LVEF should be performed, particularly with higher, cumulative anthracycline doses. The technique used for assessment should be consistent throughout follow-up.
Cardiomyopathy induced by anthracyclines is associated with persistent reduction of the QRS voltage, prolongation beyond normal limits of the systolic interval (PEP) and a reduction of the ejection fraction (LVET). Electrocardiogram (ECG) changes may be indicative of anthracyclineinduced cardiomyopathy, but ECG is not a sensitive or specific method for following anthracycline-related cardiotoxicity.
Given the risk of cardiomyopathy, a cumulative dose of 900 mg/m2 epirubicin should be exceeded only with extreme caution.
In establishing the maximal cumulative dose of epirubicin, consideration should be given to any concomitant therapy with potentially cardiotoxic drugs. A cumulative dose of 900 - 1000 mg/m2 should only be exceeded with extreme caution with both usual and high doses of epirubicin. Above this level the risk of irreversible congestive heart failure increases greatly.
Risk factors for cardiac toxicity include active or dormant cardiovascular disease, prior or concomitant radiotherapy to the mediastinal/pericardia1 area, previous therapy with other anthracyclines or anthracenediones, and concomitant use of other drugs with the ability to suppress cardiac contractility or cardiotoxic drugs (e.g., trastuzumab) (see section 4.5).
Cardiac function monitoring must be particularly strict in patients receiving high cumulative doses and in those with risk factors. Elderly patients, children and patients with a history of heart disease also have a greater risk of cardiotoxicity.
However, cardiotoxicity with epirubicin may occur at lower cumulative doses whether or not cardiac risk factors are present.
It is probable that the toxicity of epirubicin and other anthracyclines or anthracenediones is additive.
Hematologic Toxicity As with other cytotoxic agents, epirubicin may produce myelosuppression. Hematologic profiles should be assessed before and during each cycle of therapy with epirubicin, including differential white blood cell (WBC) counts. A dose-dependent, reversible leukopenia and/or granulocytopenia (neutropenia) is the predominant manifestation of epirubicin hematologic toxicity and is the most common acute dose-limiting toxicity of this drug. Leukopenia and neutropenia are generally more severe with high-dose schedules, reaching the nadir in most cases between days 10 and 14 after drug administration; this is usually transient with the WBC/neutrophil counts returning to normal values in most cases by day 21. Thrombocytopenia and anemia may also occur. Clinical consequences of severe myelosuppression include fever, infection, sepsis/septicemia, septic shock, hemorrhage, tissue hypoxia, or death.
Secondary Leukemia - Secondary leukemia, with or without a preleukemic phase, has been reported in patients treated with anthracyclines, including epirubicin. Secondary leukemia is more common when such drugs are given in combination with DNA-damaging antineoplastic agents, in combination with radiation treatment, when patients have been heavily pre-treated with cytotoxic drugs, or when doses of the anthracyclines have been escalated. These leukemias can have a 1- to 3-year latency period. (See section 5.1).
Gastrointestinal - Epirubicin is emetigenic. Mucositis/stomatitis generally appears early after drug administration and, if severe, may progress over a few days to mucosal ulcerations. Most patients recover from this adverse event by the third week of therapy.
Liver Function - The major route of elimination of epirubicin is the hepatobiliary system. Serum total bilirubin, alkaline phosphatase, AL T and AST levels should be evaluated before and during treatment with epirubicin. Patients with elevated bilirubin or AST may experience slower clearance of drug with an increase in overall toxicity. Lower doses are recommended in these patients (see sections 4.2 and 5.2). Patients with severe hepatic impairment should not receive epirubicin (see section 4.3).
Renal Function - Serum creatinine should be assessed before and during therapy. Dosage adjustment is necessary in patients with serum creatinine > 450 pmol/l (see section 4.2).
Effects at Site of Injection - Phlebosclerosis may result from an injection into a small vessel or from repeated injections into the same vein. Following the recommended administration procedures may minimize the risk of phlebitis/thrombophlebitis at the injection site (see section 4.2).
Extravasation - Extravasation of epirubicin during intravenous injection may produce local pain, severe tissue lesions (vesication, severe cellulitis) and necrosis. Should signs or symptoms of extravasation occur during intravenous administration of epirubicin, the drug infusion should be immediately discontinued. The patient's pain may be relieved by cooling down the area and keeping it cool for 24 hours. The patient should be monitored closely during the subsequent period of time, as necrosis may occur after several weeks. If extravasation occurs, a plastic surgeon should be consulted with a view to possible excision.
Other - As with other cytotoxic agents, thrombophlebitis and thromboembolic phenomena, including pulmonary embolism (in some cases fatal), have been coincidentally reported with the use of epirubicin.
Tumor-Lysis Syndrome - Epirubicin may induce hyperuricemia because of the extensive purine catabolism that accompanies rapid drug-induced lysis of neoplastic cells (tumor-lysis syndrome). Blood uric acid levels, potassium, calcium phosphate, and creatinine should be evaluated after initial treatment. Hydration, urine alkalinization, and prophylaxis with allopurinol to prevent hyperuricemia may minimize potential complications of tumor-lysis syndrome.
Immunosuppressant Effects/Increased Susceptibility to Infections - Administration of live or live-attenuated vaccines in patients immunocompromised by chemotherapeutic agents including epirubicin, may result in serious or fatal infections. (see section 4.5).
Reproductive system: Epirubicin can cause genotoxicity. Men and women treated with epirubicin should adopt appropriate contraceptives. Patients desiring to have children after completion of therapy should be advised to obtain genetic counselling if appropriate and available (see section 4.6).
Additional Warnings and Precautions for Other Routes of Administration
Intravesical route - Administration of epirubicin may produce symptoms of chemical cystitis (such as dysuria, polyuria, nocturia, stranguria, hematuria, bladder discomfort, necrosis of the bladder wall) and bladder constriction. Special attention is required for catheterization problems (e.g., uretheral obstruction due to massive intravesical tumors).
This medicinal product contains 3.5 mg sodium per ml solution for injection or infusion. To be taken into consideration by patients on a controlled sodium diet.
4.5 Interaction with other medicinal products and other forms of interaction
Epirubicin is mainly used in combination with other cytotoxic drugs. Additive toxicity may occur especially with regard to bone marrow/hematologic and gastrointestinal effects (see section 4.4). The use of epirubicin in combination chemotherapy with other potentially cardiotoxic drugs, as well as the concomitant use of other cardioactive compounds (e.g., calcium channel blockers), requires monitoring of cardiac function throughout treatment.
Epirubicin is extensively metabolized by the liver. Changes in hepatic function induced by concomitant therapies may affect epirubicin metabolism, pharmacokinetics, therapeutic efficacy and/or toxicity (see section 4.4 Special warnings and precautions for use).
Anthracyclines including epirubicin should not be administered in combination with other cardiotoxic agents unless the patient's cardiac function is closely monitored. Patients receiving anthracyclines after stopping treatment with other cardiotoxic agents, especially those with long half-lives such as trastuzumab, may also be at an increased risk of developing cardiotoxicity. The half-life of trastuzumab is approximately 28.5 days and may persist in the circulation for up to 24 weeks. Therefore, physicians should avoid anthracycline-based therapy for up to 24 weeks after stopping trastuzumab when possible. If anthracyclines are used before this time, careful monitoring of cardiac function is recommended.
Vaccination with a live vaccine should be avoided in patients receiving epirubicin. Killed or inactivated vaccines may be administered; however, the response to such vaccines may be diminished.
Medicinal products that induce the enzyme cytochrome P-450 (such as rifampicin and barbiturates) can increase the metabolism of epirubicin, resulting in a reduction of the efficacy.
Cimetidine 400 mg two times daily given prior to epirubicin 100 mg/m2 every 3 weeks led to a 50% increase in epirubicin AUC and a 41 % increase in epirubicinol AUC (latter p<0.05). The AUC of the 7-deoxy-doxorubicinol aglycone and liver blood flow were not reduced, so results are not explained by reduced cytochrome P450 activity.
Cimetidine should be discontinued during treatment with epirubicin.
When given prior to epirubicin, paclitaxel can cause increased plasma concentrations of unchanged epirubicin and its metabolites, the latter being, however, neither toxic nor active. In one study, haematological toxicity was greater when paclitaxel was administered before epirubicin compared with after epirubicin.
Coadministration of paclitaxel or docetaxel did not affect the pharmacokinetics of epirubicin when the taxane was administered after epirubicin.
Therefore administration of paclitaxel after epirubicin is recommended. Infusion of epirubicin and paclitaxel should be performed with at least a 24 hour interval between the 2 agents.
Dexverapamil may alter the pharmacokinetics of epirubicin and possibly increase its bone marrow depressant effects.
One study found that docetaxel may increase the plasma concentrations of epirubicin metabolites when administered immediately after epirubicin.
Quinine may accelerate the initial distribution of epirubicin from blood into the tissues and may have an influence on the red blood cells partitioning of epirubicin.
The co-administration of interferon a2b may cause a reduction in both the terminal elimination half-life and the total clearance of epirubicin.
The possibility of a marked disturbance of haematopoiesis needs to be kept in mind with a (pre) treatment with medications which influences the bone marrow (i.e. cytostatic agents, sulphonamide, chloramphenicol, diphenylhydantoin, amidopyrine-derivate, antiretroviral agents).
Prior administration of higher doses (900 mg/m2 and 1200 mg/m2) of dexrazoxane may increase the systemic clearance of epirubicin resulting and result in a decrease in
AUC.
The cardiotoxicity of epirubicin is potentiated by certain radiotherapeutic treatments and by previous or concomitant use of other anthracycline derivatives (e.g. mitomycin-C, dacarbazine, dactinomycin and possibly cyclophosphamide) or other cardiotoxic agents (e.g. 5- fluorouracil, cyclophosphamide, cisplatin, taxanes). Epirubicin can potentiate the effect of radiation to the mediastinal area.
If epirubicin is used concomitantly with other drugs that may cause heart failure, e.g. calcium channel blockers, then cardiac function must be monitored throughout the course of treatment.
Concomitant use with ciclosporine, may cause excessive immunosuppression.
4.6 Fertility, pregnancy and lactation
(See section 5.3).
Pregnancy
There is a limited amount of data from the use of epirubicin in pregnant woman. Studies in animals have shown reproductive toxicity (see section 5.3). If epirubicin is used during pregnancy (particularly in the first trimester) or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus and the cytostatic drugs should only be used on strict indication and when the potential benefits to the mother have been weighed against the potential risk to the fetus.
It is not known whether epirubicin is excreted in human milk. Because many drugs, including other anthracyclines, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from epirubicin, mothers should discontinue nursing prior to taking this drug.
Fertility
Epirubicin could induce chromosomal damage in human spermatozoa. Men undergoing treatment with epirubicin should use effective contraceptive methods and if appropriate and available, seek advice on sperm preservation due to the possibility of irreversible infertility caused by therapy. Male patients treated with epirubicin are advised not to father a child during and up to 6 months after treatment.
Epirubicin may cause amenorrhea or premature menopause in premenopausal women. Women should not become pregnant during treatment with epirubicin. Men and women should use an effective method of contraception during treatment and for 6 months thereafter.
4.7 Effects on ability to drive and use machines
The effect of epirubicin on the ability to drive or use machinery has not been systematically evaluated.
However, epirubicin may cause episodes of nausea and vomiting, which can temporarily lead to an impairment of ability to drive or operate machines.
4.8 Undesirable effects
The following undesirable effects have been observed and reported during treatment with epirubicin with the following frequencies: Very common (>1/10); common (>1/100 to <1/10); uncommon (>1/1,000 to < 1/100); rare (>1/10,000 to <1/1,000); very rare (<1/10,000), not known (cannot be estimated form the available data)
More than 10% of treated patients can expect to develop undesirable effects. The most common undesirable effects are myelosuppression, gastrointestinal side effects, anorexia, alopecia, infection.

Blood and the lymphatic system disorders:
High doses of epirubicin have been safely administered in a large number of untreated patients having various solid tumours and have caused adverse events which are not different from those seen at conventional doses with the exception of reversible severe neutropenia
(< 500 neutrophils/mm3 for < 7 days) which occurred in the majority of patients. Only few patients required hospitalisation and supportive therapy for severe infectious complications at high doses.
General disorders and administration site conditions:
Local pain and tissue necrosis (following accidental paravenous injection) may occur.
Intravesical administration:
As only a small amount of active ingredient is reabsorbed after intravesical instillation, severe systemic adverse drug reactions as well as allergic reactions are rare. Commonly reported are local reactions like burning sensation and frequent voiding (pollakisuria).Occasional bacterial or chemical cystitis have been reported (see section 4.4). These ADRs are mostly reversible.
4.9 Overdose
Acute overdosage with epirubicin will result in severe myelosuppression (within 1014 days; mainly leukopenia and thrombocytopenia), gastrointestinal toxic effects (mainly mucositis) and acute cardiac complications (within 24 hours). During this period a blood transfusion is required as well as isolation in a sterile room. Latent cardiac failure has been observed with anthracyclines several months to years after completion of treatment (see section 4.4). Patients must be carefully monitored. If signs of cardiac failure occur, patients should be treated according to conventional guidelines.
Treatment:
Symptomatic. Epirubicin cannot be removed by dialysis.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antineoplastic agents, anthracyclines and related substances.
ATC-code: L0lDB03
The working mechanism of epirubicin is depends on its ability to form complexes with DNA. Experimental studies with cell cultures have shown that epirubicin rapidly penetrates the cell and is recovered in the nucleus where it inhibits the nucleic acid synthesis and the mitosis. The activity of epirubicin was established on many experimental tumours, amongst which leucaemias L12l0 and P388, the sarcoma SA 180 (solid and ascetic form), the B16 melanoma, the breast carcinoma, the lung carcinoma of Lewis and the colon carcinoma 38, furthermore an effect was also shown on human tumours that were transplanted in athymic nude mice (melanoma and mammary, lung, prostate and ovarian carcinoma).
5.2 Pharmacokinetic properties
In patients with a normal liver and kidney function the plasma level of epirubicin drops after an intravenous injection of 60-150 mg/m2 in a tri-exponential way with a very rapid first phase and a slow last phase with a mean half life of about 40 hours. These doses fall within the limits of the pharmacokinetic linearity both concerning the plasma clearance values and the metabolism. Distribution studies in rats have shown that epirubicin does not cross the blood-brain barrier. The high plasma clearance values of epirubicin (0.9 l/min) and the slow elimination methods indicate a large distribution volume.
Biotransformation
The most important metabolites that were identified are epirubicinol (13-OH epirubicin), glucuronides of epirubicin and of epirubicinol. The 4’ -O-glucuronidation distinguishes epirubicin from doxorubicin and can explain the faster elimination of epirubicin and its reduced toxicity. Plasma levels of the most important metabolite, epirubicinol, are always lower than those of the unchanged product and run practically parallel.
Excretion
Approximately 9-10% of the administered dose is excreted via the urine within 48 hours. Epirubicin is primarily excreted via the liver; approximately 40% of the administered dose is recovered in the bile within 72 hours. A liver function disorder causes higher plasma levels and requires a dose reduction.
5.3 Preclinical safety data
Following repeated dosing with epirubicin, the target organs in rat, rabbit and dog were the haemolymphopoietic system, GI tract, kidney, liver and reproductive organs, Epirubicin was also cardiotoxic in rat, rabbit and dog.
Epirubicin was mutagenic, genotoxic, embryotoxic and carcinogenic in rats.
Peri/postnatal studies in rat indicate adverse effects on the offspring at clinical doses. It is not known whether epirubicin is excreted in breast milk.
No malformations were seen in rats or rabbits, but like other anthracyclines and cytotoxic drugs, epirubicin must be considered potentially teratogenic.
A local tolerance study in rats and mice showed extravasation of epirubicin causes tissue necrosis.
