Daunorubicina GP Pharme (daunorubicin) is contraindicated in patients who have shown a hypersensitivity to it.
Dose-limiting toxicity includes myelosuppression and cardiotoxicity (See WARNINGS). Other reactions include:
Cutaneous: Reversible alopecia occurs in most patients. Rash, contact dermatitis and urticaria have occurred rarely.
Gastrointestinal:Acute nausea and vomiting occur but are usually mild. Antiemetic therapy may be of some help. Mucositis may occur 3 to 7 days after administration. Diarrhea and abdominal pain have occasionally been reported.
Local: If extravasation occurs during administration, severe local tissue necrosis, severe celluli-tis, thrombophlebitis, or painful induration can result.
Acute Reactions: Rarely, anaphylactoid reaction, fever, and chills can occur. Hyperuricemia may occur, especially in patients with leukemia, and serum uric acid levels should be monitored.
Daunorubicina GP Pharme (daunorubicin) in combination with other approved anticancer drugs is indicated for remission induction in acute nonlymphocytic leukemia (myelogenous, monocytic, erythroid) of adults and for remission induction in acute lymphocytic leukemia of children and adults.
General: Following intravenous injection of Daunorubicina GP Pharme (daunorubicin) , plasma levels of daunorubicin decline rapidly, indicating rapid tissue uptake and concentration. Thereafter, plasma levels decline slowly with a half-life of 45 minutes in the initial phase and 18.5 hours in the terminal phase. By 1 hour after drug administration, the predominant plasma species is daunorubicinol, an active metabolite, which disappears with a half-life of 26.7 hours.
Distribution: Daunorubicina GP Pharme (daunorubicin) is rapidly and widely distributed in tissues, with highest levels in the spleen, kidneys, liver, lungs, and heart. The drug binds to many cellular components, particularly nucleic acids. There is no evidence that Daunorubicina GP Pharme (daunorubicin) crosses the blood-brain barrier, but the drug apparently crosses the placenta.
Metabolism and Elimination: Daunorubicina GP Pharme (daunorubicin) is extensively metabolized in the liver and other tissues, mainly by cytoplasmic aldo-keto reductases, producing daunorubicinol, the major metabolite which has antineoplastic activity. Approximately 40% of the drug in the plasma is present as daunorubicinol within 30 minutes and 60% in 4 hours after a dose of daunorubicin. Further metabolism via reduction cleavage of the glycosidic bond, 4-O demethylation, and conjugation with both sulfate and glucuronide have been demonstrated. Simple glycosidic cleavage of daunorubicin or daunorubicinol is not a significant metabolic pathway in man. Twenty-five percent of an administered dose of Daunorubicina GP Pharme (daunorubicin) is eliminated in an active form by urinary excretion and an estimated 40% by biliary excretion.
Bone Marrow: Daunorubicina GP Pharme (daunorubicin) is a potent bone marrow suppressant. Suppression will occur in all patients given a therapeutic dose of this drug. Therapy with Daunorubicina GP Pharme (daunorubicin) should not be started in patients with pre-existing drug-induced bone marrow suppression unless the benefit from such treatment warrants the risk. Persistent, severe myelosuppression may result in superinfection or hemorrhage.
Cardiac Effects: Special attention must be given to the potential cardiac toxicity of Daunorubicina GP Pharme (daunorubicin) , particularly in infants and children. Pre-existing heart disease and previous therapy with doxorubicin are co-factors of increased risk of Daunorubicina GP Pharme (daunorubicin) -induced cardiac toxicity and the benefit-to-risk ratio of Daunorubicina GP Pharme (daunorubicin) therapy in such patients should be weighed before starting Daunorubicina GP Pharme (daunorubicin). In adults, at total cumulative doses less than 550 mg/m2, acute congestive heart failure is seldom encountered. However, rare instances of pericarditis-myocarditis, not dose-related, have been reported.
In adults, at cumulative doses exceeding 550 mg/m2, there is an increased incidence of drug-induced congestive heart failure. Based on prior clinical experience with doxorubicin, this limit appears lower, namely 400 mg/m2, in patients who received radiation therapy that encompassed the heart.
In infants and children, there appears to be a greater susceptibility to anthracycline-induced car-diotoxicity compared to that in adults, which is more clearly dose-related. Anthracycline therapy (including daunorubicin) in pediatric patients has been reported to produce impaired left ventricular systolic performance, reduced contractility, congestive heart failure or death. These conditions may occur months to years following cessation of chemotherapy. This appears to be dose-dependent and aggravated by thoracic irradiation. Long-term periodic evaluation of cardiac function in such patients should, thus, be performed. In both children and adults, the total dose of Daunorubicina GP Pharme (daunorubicin) administered should also take into account any previous or concomitant therapy with other potentially cardiotoxic agents or related compounds such as doxorubicin.
There is no absolutely reliable method of predicting the patients in whom acute congestive heart failure will develop as a result of the cardiac toxic effect of Daunorubicina GP Pharme (daunorubicin). However, certain changes in the electrocardiogram and a decrease in the systolic ejection fraction from pre-treatment baseline may help to recognize those patients at greatest risk to develop congestive heart failure. On the basis of the electrocardiogram, a decrease equal to or greater than 30% in limb lead QRS voltage has been associated with a significant risk of drug-induced cardiomyopathy. Therefore, an electrocardiogram and/or determination of systolic ejection fraction should be performed before each course of Daunorubicina GP Pharme (daunorubicin). In the event that one or the other of these predictive parameters should occur, the benefit of continued therapy must be weighed against the risk of producing cardiac damage. Early clinical diagnosis of drug-induced congestive heart failure appears to be essential for successful treatment.
Evaluation of Hepatic and Renal Function: Significant hepatic or renal impairment can enhance the toxicity of the recommended doses of Daunorubicina GP Pharme (daunorubicin) ; therefore, prior to administration, evaluation of hepatic function and renal function using conventional clinical laboratory tests is recommended (See DOSAGE AND ADMINISTRATION).
Pregnancy: Daunorubicina GP Pharme (daunorubicin) may cause fetal harm when administered to a pregnant woman. An increased incidence of fetal abnormalities (parieto-occipital cranioschisis, umbilical hernias, or rachischisis) and abortions was reported in rabbits at doses of 0.05 mg/kg/day or approximately 1/100th of the highest recommended human dose on a body surface area basis. Rats showed an increased incidence of esophageal, cardiovascular and urogenital abnormalities as well as rib fusions at doses of 4 mg/kg/day or approximately 1/2 the human dose on a body surface area basis. Decreases in fetal birth weight and post-delivery growth rate were observed in mice. There are no adequate and well-controlled studies in pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant.
Secondary Leukemias: There have been reports of secondary leukemias in patients exposed to topoi-somerase II inhibitors when used in combination with other antineoplastic agents or radiation therapy.
Extravasation at Injection Site: Extravasation of Daunorubicina GP Pharme (daunorubicin) at the site of intravenous administration can cause severe local tissue necrosis. (See ADVERSE REACTIONS)
PRECAUTIONSGeneral: Therapy with Daunorubicina GP Pharme (daunorubicin) requires close patient observation and frequent complete blood-count determinations. Cardiac, renal, and hepatic function should be evaluated prior to each course of treatment.
Appropriate measures must be taken to control any systemic infection before beginning therapy with Daunorubicina GP Pharme (daunorubicin).
Daunorubicina GP Pharme (daunorubicin) may transiently impart a red coloration to the urine after administration, and patients should be advised to expect this.
Laboratory Tests: Daunorubicina GP Pharme (daunorubicin) may induce hyperuricemia secondary to rapid lysis of leukemic cells. As a precaution, allopurinol administration is usually begun prior to initiating antileukemic therapy. Blood uric acid levels should be monitored and appropriate therapy initiated in the event that hyperuricemia develops.
Carcinogenesis, Mutagenesis, Impairment of Fertility: Daunorubicina GP Pharme (daunorubicin) , when injected subcutaneously into mice, causes fibrosarcomas to develop at the injection site. When administered to mice thrice weekly intraperitoneally, no carcinogenic effect was noted after 18 months of observation. In male rats administered Daunorubicina GP Pharme (daunorubicin) thrice weekly for 6 months, at 1/70th the recommended human dose on a body surface area basis, peritoneal sarcomas were found at 18 months. A single IV dose of Daunorubicina GP Pharme (daunorubicin) administered to rats at 1.6 fold the recommended human dose on a body surface area basis caused mammary adenocarcinomas to appear at 1 year. Daunorubicina GP Pharme (daunorubicin) was mutagenic in vitro (Ames assay, V79 hamster cell assay), and clastogenic in vitro (CCRFCEM human lymphoblasts) and in vivo (SCE assay in mouse bone marrow) tests. In male dogs at a daily dose of 0.25 mg/kg administered intravenously, testicular atrophy was noted at autopsy. Histologic examination revealed total aplasia of the spermatocyte series in the seminiferous tubules with complete aspermatogenesis.
Pregnancy Category D (See WARNINGS)
Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Daunorubicina GP Pharme (daunorubicin) , mothers should be advised to discontinue nursing during Daunorubicina GP Pharme therapy.
Elderly: See CLINICAL PHARMACOLOGY, Special Populations, Geriatric Patients.
Pediatric Use: See CLINICAL PHARMACOLOGY, Special Populations, Pediatric Patients and WARNINGS, Cardiac Effects.
Parenteral drug products should be inspected visually for particulate matter prior to administration, whenever solution and container permit.
Principles: In order to eradicate the leukemic cells and induce a complete remission, a profound suppression of the bone marrow is usually required. Evaluation of both the peripheral blood and bone marrow is mandatory in the formulation of appropriate treatment plans.
It is recommended that the dosage of Daunorubicina GP Pharme (daunorubicin) be reduced in instances of hepatic or renal impairment. For example, using serum bilirubin and serum creatinine as indicators of liver and kidney function, the following dose modifications are recommended:
| Serum Bilirubin | Serum Creatinine | Dose Reduction |
| 1.2 to 3.0 mg% | - | 25% |
| >3 mg% | - | 50% |
| - | >3 mg% | 50% |
Representative Dose Schedules and Combination for the Approved Indication of Remission Induction in Adult Acute Nonlymphocytic Leukemia:
In Combination: For patients under age 60, Daunorubicina GP Pharme (daunorubicin) 45 mg/m2/day IV on days 1, 2, and 3 of the first course and on days 1, 2 of subsequent courses AND cytosine arabinoside 100 mg/m2/day IV infusion daily for 7 days for the first course and for 5 days for subsequent courses.
For patients 60 years of age and above, Daunorubicina GP Pharme (daunorubicin) 30 mg/m2/day IV on days 1, 2, and 3 of the first course and on days 1, 2 of subsequent courses AND cytosine arabinoside 100 mg/m2/day IV infusion daily for 7 days for the first course and for 5 days for subsequent courses. This Daunorubicina GP Pharme (daunorubicin) dose-reduction is based on a single study and may not be appropriate if optimal supportive care is available.
The attainment of a normal-appearing bone marrow may require up to three courses of induction therapy. Evaluation of the bone marrow following recovery from the previous course of induction therapy determines whether a further course of induction treatment is required.
Representative Dose Schedule and Combination for the Approved Indication of Remission Induction in Pediatric Acute Lymphocytic Leukemia:
In Combination: Daunorubicina GP Pharme (daunorubicin) 25 mg/m2 IV on day 1 every week, vincristine 1.5 mg/m2 IV on day 1 every week, prednisone 40 mg/m2 PO daily. Generally, a complete remission will be obtained within four such courses of therapy; however, if after four courses the patient is in partial remission, an additional one or, if necessary, two courses may be given in an effort to obtain a complete remission.
In children less than 2 years of age or below 0.5 m2 body surface area, it has been recommended that the Daunorubicina GP Pharme (daunorubicin) dosage calculation should be based on weight (1 mg/kg) instead of body surface area.
Representative Dose Schedules and Combination for the Approved Indication of Remission Induction in Adult Acute Lymphocytic Leukemia:
In Combination: Daunorubicina GP Pharme (daunorubicin) 45 mg/m2/day IV on days 1, 2, and 3 AND vincristine 2 mg IV on days 1, 8, and 15; prednisone 40 mg/m2/day PO on days 1 through 22, then tapered between days 22 to 29; L-asparaginase 500 IU/kg/day x 10 days IV on days 22 through 32.
The contents of a vial should be reconstituted with 4 mL of Sterile Water for Injection and agitated gently until the material has completely dissolved. The sterile vial contents provide 20 mg of daunorubicin, with 5 mg of daunorubicin per mL. The desired dose is withdrawn into a syringe containing 10 mL to 15 mL of 0.9% Sodium Chloride Injection, USP and then injected into the tubing or sidearm in a rapidly flowing IV infusion of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP. Daunorubicina GP Pharme (daunorubicin) should not be administered mixed with other drugs or heparin.
Storage and Handling: Store unreconstituted powder at controlled room temperature, 15° to 30°C (59° to 86°F). The reconstituted solution is stable for 24 hours at room temperature and 48 hours under refrigeration. It should be protected from exposure to sunlight. Protect from light. Retain in carton until time of use.
If Daunorubicina GP Pharme (daunorubicin) contacts the skin or mucosae, the area should be washed thoroughly with soap and water. Procedures for proper handling and disposal of anticancer drugs should be considered. Several guidelines on this subject have been published.1-7 There is no general agreement that all of the procedures recommended in the guidelines are necessary or appropriate.
