DESCRIPTION

Dexrazoxane for Injection is a sterile, pyrogen-free lyophilizate intended for intravenous administration. It is a cardioprotective agent for use in conjunction with doxorubicin.

Chemically, dexrazoxane is (+)-(S)-4,4’-Propylenedi-2,6-piperazinedione. The structural formula is as follows:

structural formula

C11H16N404                                                                                                           M.W. 268.27

Dexrazoxane, a potent intracellular chelating agent is a derivative of EDTA. Dexrazoxane is a whitish crystalline powder which melts at 191° to 197°C. It is sparingly soluble in water and 0.1 N HCI, slightly soluble in ethanol and methanol and practically insoluble in nonpolar organic solvents. The pKa is 2.1. Dexrazoxane has an octanol/water partition coefficient of 0.025 and degrades rapidly above a pH of 7.0.

Each 250 mg vial contains dexrazoxane hydrochloride equivalent to 250 mg dexrazoxane. Hydrochloric acid is added for pH adjustment. When reconstituted as directed with the 25 mL vial of 0.167 Molar (M/6) Sodium Lactate Injection USP diluent provided, each mL contains: 10 mg dexrazoxane. The pH of the resultant solution is 3.5 to 5.5.

Each 500 mg vial contains dexrazoxane hydrochloride equivalent to 500 mg dexrazoxane. Hydrochloric acid is added for pH adjustment. When reconstituted as directed with the 50 mL vial of 0.167 Molar (M/6) Sodium Lactate Injection USP diluent provided, each mL contains: 10 mg dexrazoxane. The pH of the resultant solution is 3.5 to 5.5.

CLINICAL PHARMACOLOGY

Mechanism of Action

The mechanism by which dexrazoxane exerts its cardioprotective activity is not fully understood. Dexrazoxane is a cyclic derivative of EDTA that readily penetrates cell membranes. Results of laboratory studies suggest that dexrazoxane is converted intracellularly to a ring-opened chelating agent that interferes with iron-mediated free radical generation thought to be responsible, in part, for anthracycline-induced cardiomyopathy.

Pharmacokinetics

The pharmacokinetics of dexrazoxane have been studied in advanced cancer patients with normal renal and hepatic function. Generally, the pharmacokinetics of dexrazoxane can be adequately described by a two-compartment open model with first-order elimination. Dexrazoxane has been administered as a 15 minute infusion over a dose-range of 60 to 900 mg/m2 with 60 mg/m2 of doxorubicin, and at a fixed dose of 500 mg/m2 with 50 mg/m2 doxorubicin. The disposition kinetics of dexrazoxane are dose-independent, as shown by linear relationship between the area under plasma concentration-time curves and administered doses ranging from 60 to 900 mg/m2. The mean peak plasma concentration of dexrazoxane was 36.5 mcg/mL at the end of the 15 minute infusion of a 500 mg/m2 dose of dexrazoxane administered 15 to 30 minutes prior to the 50 mg/m2 doxorubicin dose. The important pharmacokinetic parameters of dexrazoxane are summarized in the following table:

60 600 5 2.1 (29) 6.25 (31) ------ 22.0 (55)

Following a rapid distributive phase (~0.2 to 0.3 hours), dexrazoxane reaches post-distributive equilibrium within two to four hours. The estimated steady-state volume of distribution of dexrazoxane suggests its distribution primarily in the total body water (25 L/m2). The mean systemic clearance and steady-state volume of distribution of dexrazoxane in two Asian female patients at 500 mg/m2 dexrazoxane along with 50 mg/m2 doxorubicin were 15.15 L/h/m2 and 36.27 L/m2, respectively, but their elimination half-life and renal clearance of dexrazoxane were similar to those of the ten Caucasian patients from the same study. Qualitative metabolism studies with dexrazoxane have confirmed the presence of unchanged drug, a diacid-diamide cleavage product, and two monoacid-monoamide ring products in the urine of animals and man. The metabolite levels were not measured in the pharmacokinetic studies.

Urinary excretion plays an important role in the elimination of dexrazoxane. Forty-two percent of the 500 mg/m2 dose of dexrazoxane was excreted in the urine.

Protein Binding: In vitro studies have shown that dexrazoxane is not bound to plasma proteins.

Special Populations

Pediatric

The pharmacokinetics of dexrazoxane have not been evaluated in pediatric patients.

Gender

Analysis of pooled data from two pharmacokinetic studies indicate that male patients have a lower mean clearance value than female patients (110 mL/min/m2 versus 133 mL/min/m2). This gender effect is not clinically relevant.

Renal Insufficiency

The pharmacokinetics of dexrazoxane were assessed following a single 15 minute IV infusion of 150 mg/m2 of dexrazoxane in male and female subjects with varying degrees of renal dysfunction as determined by creatinine clearance (CLCR) based on a 24 hour urinary creatinine collection. Dexrazoxane clearance was reduced in subjects with renal dysfunction. Compared with controls, the mean AUC0-inf value was twofold greater in subjects with moderate (CLCR 30 to 50 mL/min) to severe (CLCR <30 mL/min) renal dysfunction. Modeling demonstrated that equivalent exposure (AUC0-inf) could be achieved if dosing were reduced by 50% in subjects with creatinine clearance values <40 mL/min compared with control subjects (CLCR >80 mL/min) (see PRECAUTIONS, DOSAGE AND ADMINISTRATION).

Hepatic Insufficiency

The pharmacokinetics of dexrazoxane have not been evaluated in patients with hepatic impairment. The dexrazoxane dose is dependent upon the dose of doxorubicin (see DOSAGE AND ADMINISTRATION). Since a doxorubicin dose reduction is recommended in the presence of hyperbilirubinemia, the dexrazone dosage is proportionately reduced in patients with hepatic impairment.

Drug Interactions

There was no significant change in the pharmacokinetics of doxorubicin (50 mg/m2) and its predominant metabolite, doxorubicinol, in the presence of dexrazoxane (500 mg/m2) in a crossover study in cancer patients.

Clinical Studies

The ability of dexrazoxane to prevent/reduce the incidence and severity of doxorubicin-induced cardiomyopathy was demonstrated in three prospectively randomized placebo-controlled studies. In these studies, patients were treated with a doxorubicin-containing regimen and either dexrazoxane or placebo starting with the first course of chemotherapy. There was no restriction on the cumulative dose of doxorubicin. Cardiac function was assessed by measurement of the left ventricular ejection fraction (LVEF), utilizing resting multigated nuclear medicine (MUGA) scans, and by clinical evaluations. Patients receiving dexrazoxane had significanily smaller mean decreases from baseline in LVEF and lower incidences of congestive heart failure than the control group. The difference in decline from baseline in LVEF was evident beginning with a cumulative doxorubicin dose of 150 mg/m2 and reached statistical significance in patients who received ≥400 mg/m2 of doxorubicin. In addition to evaluating the effect of dexrazoxane on cardiac function, the studies also assessed the effect of the addition of dexrazoxane on the antitumor efficacy of the chemotherapy regimens. In one study (the largest of three breast cancer studies) patients with advanced breast cancer receiving fluorouracil, doxorubicin and cyclophosphamide (FAC) with dexrazoxane had a lower response rate (48% vs 63%; p=0.007) and a shorter time to progression than patients who received FAC + placebo, although the survival of patients who did or did not receive dexrazoxane with FAC was similar.

Two of the randomized breast cancer studies evaluating the efficacy and safety of FAC with either dexrazoxane or placebo were amended to allow patients on the placebo arm who had attained a cumulative dose of doxorubicin of 300 mg/m2 (six courses of FAC) to receive FAC with open-label dexrazoxane for each subsequent course. This change in design allowed examination of whether there was a cardioprotective effect of dexrazoxane even when it was started after substantial exposure to doxorubicin.

Retrospective historical analyses were then performed to compare the likelihood of heart failure in patients to whom dexrazoxane was added to the FAC regimen after they had received six (6) courses of FAC (and who then continued treatment with FAC therapy) with the heart failure rate in patients who had received six (6) courses of FAC and continued to receive this regimen without added dexrazoxane. These analyses showed that the risk of experiencing a cardiac event (see Table 1 for definition) at a given cumulative dose of doxorubicin above 300 mg/m2 was substantially greater in the 99 patients who did not receive dexrazoxane beginning with their seventh course of FAC than in the 102 patients who did receive dexrazoxane (See Figure 1).

Table 1 The development of cardiac events is shown by:
  1. Development of congestive heart failure, defined as having two or more of the following:
    a. Cardiomegaly by X-ray
    b. Basilar Rales
    c. S3 Gallop
    d. Paroxysmal nocturnal dyspnea and/or orthopnea and/or significant dyspnea on exertion.
  2. Decline from baseline in LVEF by ≥10% and to below the lower limit of normal for the institution.
  3. Decline in LVEF by ≥20% from baseline value.
  4. Decline in LVEF to ≥5% below lower limit of normal for the institution.

Figure 1 displays the risk of developing congestive heart failure by cumulative dose of doxorubicin in patients who received dexrazoxane starting with their seventh course of FAC compared to patients who did not. Patients unprotected by dexrazoxane had a 13 times greater risk of developing congestive heart failure. Overall, 3% of patients treated with dexrazoxane developed CHF compared with 22% of patients not receiving dexrazoxane.

Figure one

Because of its cardioprotective effect, dexrazoxane permitted a greater percentage of patients to be treated with extended doxorubicin therapy. Figure 2 shows the number of patients still on treatment at increasing cumulative doses.

Figure two

In addition to evaluating the cardioprotective efficacy of dexrazoxane in this setting, the time to tumor progression and survival of these two groups of patients were also compared. There was a similar time to progression in the two groups and survival was at least as long for the group of patients that received dexrazoxane starting with their seventh course, i.e., starting after a cumulative dose of doxorubicin of 300 mg/m2. These time to progression and survival data should be interpreted with caution, however, because they are based on comparisons of groups entered sequentially in the studies and are not comparisons of prospectively randomized patients.

INDICATIONS AND USAGE

Dexrazoxane is indicated for reducing the incidence and severity of cardiomyopathy associated with doxorubicin administration in women with metastatic breast cancer who have received a cumulative doxorubicin dose of 300 mg/m2 and who will continue to receive doxorubicin therapy to maintain tumor control. lt is not recommended for use with the initiation of doxorubicin therapy (see WARNINGS).

CONTRAINDICATIONS

Dexrazoxane should not be used with chemotherapy regimens that do not contain an anthracycline.

WARNINGS

Dexrazoxane may add to the myelosuppression caused by chemotherapeutic agents.

There is some evidence that the use of dexrazoxane concurrently with the initiation of fluorouracil, doxorubicin and cyclophosohamide (FAC) therapy interferes with the antitumor efficacy of the regimen, and this use is not recommended. In the largest of three breast cancer trials, patients who received dexrazoxane starting with their first cycle of FAC therapy had a lower response rate (48% vs 63%; p=0.007) and shorter time to progression than patients who did not receive dexrazoxane (see CLINICAL PHARMACOLOGY: Clinical Studies). Therefore, dexrazoxane should only be used in those patients who have received a cumulative doxorubicin dose of 300 mg/m2 and are continuing with doxorubicin therapy.

Although clinical studies have shown that patients receiving FAC with dexrazoxane may receive a higher cumulative dose of doxorubicin before experiencing cardiac toxicity than patients receiving FAC without dexrazoxane, the use of dexrazoxane in patients who have already received a cumulative dose of doxorubicin of 300 mg/m2 without dexrazoxane, does not eliminate the potential for anthracycline induced cardiac toxicity. Therefore, cardiac function should be carefully monitored.

Secondary malignancies (primarily acute myeloid leukemia) have been reported in patients treated chronically with oral razoxane. Razoxane is the racemic mixture, of which dexrazoxane is the S(+)-enantiomer. In these patients, the total cumulative dose of razoxane ranged from 26 to 480 grams and the duration of treatment was from 42 to 319 weeks. One case of T-cell lymphoma, a case of B-cell lymphoma and six to eight cases of cutaneous basal cell or squamous cell carcinoma have also been reported in patients treated with razoxane.

PRECAUTIONS

General

Doxorubicin should not be given prior to the intravenous injection of dexrazoxane. Dexrazoxane should be given by slow I.V. push or rapid drip intravenous infusion from a bag. Doxorubicin should be given within 30 minutes after beginning the infusion with dexrazoxane. (See DOSAGE AND ADMINISTRATION.)

As dexrazoxane will always be used with cytotoxic drugs, patients should be monitored closely. While the myelosuppressive effects of dexrazoxane at the recommended dose are mild, additive effects upon the myelosuppressive activity of chemotherapeutic agents may occur.

Patients with Moderate or Severe Renal Insufficiency

Greater exposure to dexrazoxane may occur in patients with compromised renal function. The dexrazoxane dose should be reduced by 50% in patients with creatinine clearance values <40 mL/min (see DOSAGE AND ADMINISTRATION).

Laboratory Tests

As dexrazoxane may add to the myelosuppressive effects of cytotoxic drugs, frequent complete blood counts are recommended. (See ADVERSE REACTIONS.)

Drug Interactions

Dexrazoxane does not influence the pharmacokinetics of doxorubicin.

Carcinogenesis, Mutagenesis, Impairment of Fertility

(See WARNINGS section for information on human carcinogenicity) - No long-term carcinogenicity studies have been carried out with dexrazoxane in animals. Dexrazoxane was not mutagenic in the Ames test but was found to be clastogenic to human lymphocytes in vitro and to mouse bone marrow erythrocytes in vivo (micronucleus test).

The possible adverse effects of dexrazoxane on the fertility of humans and experimental animals, male or female, have not been adequately studied. Testicular atrophy was seen with dexrazoxane administration at doses as low as 30 mg/kg weekly for 6 weeks in rats (1/3 the human dose on a mg/m2 basis) and as low as 20 mg/kg weekly for 13 weeks in dogs (approximately equal to the human dose on a mg/m2 basis).

Pregnancy

Teratogenic Effects; Pregnancy Category C

Dexrazoxane was maternotoxic at doses of 2 mg/kg (1/40 the human dose on a mg/m2 basis) and embryotoxic and teratogenic at 8 mg/kg (approximately 1/10 the human dose on a mg/m2 basis) when given daily to pregnant rats during the period of organogenesis. Teratogenic effects in the rat included imperforate anus, microphthalmia, and anophthalmia. In offspring allowed to develop to maturity, fertility was impaired in the male and female rats treated in utero during organogenesis at 8 mg/kg. In rabbits, doses of 5 mg/kg (approximately 1/10 the human dose on a mg/m2 basis) daily during the period of organogenesis were maternotoxic and dosages of 20 mg/kg (1/2 the human dose on a mg/m2 basis) were embryotoxic and teratogenic. Teratogenic effects in the rabbit included several skeletal malformations such as short tail, rib and thoracic malformations, and soft tissue variations including subcutaneous, eye and cardiac hemorrhagic areas, as well as agenesis of the gallbladder and of the intermediate lobe of the lung. There are no adequate and well-controlled studies in pregnant women. Dexrazoxane should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nursing Mothers

It is not known whether dexrazoxane 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 exposed to dexrazoxane, mothers should be advised to discontinue nursing during dexrazoxane therapy.

Pediatric Use

Safety and effectiveness of dexrazoxane in pediatric patients have not been established.

Geriatric Use

Clinical studies of dexrazoxane did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, elderly patients should be treated with caution due to the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease or other drug therapy.

ADVERSE REACTIONS

Dexrazoxane at a dose of 500 mg/m2 has been administered in combination with FAC in randomized, placebo-controlled, double-blind studies to patients with metastatic breast cancer. The dose of doxorubicin was 50 mg/m2 in each of the trials. Courses were repeated every three weeks, provided recovery from toxicity had occurred. Table 2 below lists the incidence of adverse experiences for patients receiving FAC with either dexrazoxane or placebo in the breast cancer studies. Adverse experiences occurring during courses 1 through 6 are displayed for patients receiving dexrazoxane or placebo with FAC beginning with their first course of therapy (column 1 & 3, respectively). Adverse experiences occurring at course 7 and beyond for patients who received placebo with FAC during the first six courses and who then received either dexrazoxane or placebo with FAC are also displayed (column 2 & 4, respectively).

The adverse experiences listed above are likely attributable to the FAC regimen with the exception of pain on injection that was observed mainly on the dexrazoxane arm.

Myelosuppression

Patients receiving FAC with dexrazoxane experienced more severe leukopenia, granulocytopenia and thrombocytopenia at nadir than patients receiving FAC without dexrazoxane, but recovery counts were similar for the two groups of patients.

Hepatic and Renal

Some patients receiving FAC + dexrazoxane or FAC + placebo experienced marked abnormalities in hepatic or renal function tests, but the frequency and severity of abnormalities in bilirubin, alkaline phosphatase, BUN, and creatinine were similar for patients receiving FAC with or without dexrazoxane.

OVERDOSAGE

There have been no instances of drug overdose in the clinical studies sponsored by either Pharmacia & Upjohn Company or the National Cancer Institute. The maximum dose administered during the cardioprotective trials was 1000 mg/m2 every three weeks.

Disposition studies with dexrazoxane have not been conducted in cancer patients undergoing dialysis, but retention of a significant dose fraction (>0.4) of the unchanged drug in the plasma pool, minimal tissue partitioning or binding, and availability of greater than 90% of the systemic drug levels in the unbound form suggest that it could be removed using conventional peritoneal or hemodialysis.

There is no known antidote for dexrazoxane. Instances of suspected overdose should be managed with good supportive care until resolution of myelosuppression and related conditions is complete. Management of overdose should include treatment of infections, fluid regulation, and maintenance of nutritional requirements.

DOSAGE AND ADMINISTRATION

The recommended dosage ratio of dexrazoxane:doxorubicin is 10:1 (e.g., 500 mg/m2 dexrazoxane:50 mg/m2 doxorubicin). In patients with moderate to severe renal dysfunction (creatinine clearance values <40 mL/min), the recommended dosage ratio of dexrazoxane:doxorubicin is 5:1 (e.g., 250 mg/m2 dexrazoxane:50 mg/m2 doxorubicin). Creatinine clearance can be determined from a 24 hour urinary creatinine collection or estimated using the Crockroft-Gault equation (assuming stable renal function):

 
CLCR=[140-age (years)] x weight (kg) {x 0.85 for female patients}
———————————————————————————
                              72 x serum creatinine (mg/dL)

Since a doxorubicin dose reduction is recommended in the presence of hyperbilirubinemia, the dexrazoxane dosage should be proportionately reduced (maintaining the 10:1 ratio) in patients with hepatic impairment. Dexrazoxane must be reconstituted with 0.167 Molar (M/6) Sodium Lactate Injection USP to give a concentration of 10 mg dexrazoxane for each mL of sodium lactate. The reconstituted solution should be given by slow I.V. push or rapid drip intravenous infusion from a bag. After completing the infusion of dexrazoxane, and prior to a total elapsed time of 30 minutes (from the beginning of the dexrazoxane infusion), the intravenous injection of doxorubicin should be given.

Reconstituted dexrazoxane, when transferred to an empty infusion bag, is stable for 6 hours from the time of reconstitution when stored at 20° to 25°C (68° to 77°F), see USP controlled room temperature, or under refrigeration, 2° to 8°C (36° to 46°F). DISCARD UNUSED SOLUTIONS.

The reconstituted dexrazoxane solution may be diluted with either 0.9% Sodium Chloride Injection or 5% Dextrose Injection to a concentration range of 1.3 to 5 mg/mL in intravenous infusion bags. The resultant solutions are stable for 6 hours when stored at 20° to 25°C (68° to 77°F), see USP controlled room temperature, or under refrigeration, 2° to 8°C (36° to 46°F). DISCARD UNUSED SOLUTIONS.

Incompatibility

Dexrazoxane should not be mixed with other drugs.

Handling and Disposal

Caution in the handling and preparation of the reconstituted solution must be exercised and the use of gloves is recommended. If dexrazoxane powder or solutions contact the skin or mucosae, immediately wash thoroughly with soap and water.

Procedures normally used for proper handling and disposal of anticancer drugs should be considered for use with dexrazoxane. Several guidelines on this subject have been published.1-8 There is no general agreement that all of the procedures recommended in the guidelines are necessary or appropriate.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
