Warning: Myelosuppression And Pulmonary Toxicity
Myelosuppression
Carmustine for injection causes suppression of marrow function (including thrombocytopenia and leukopenia), which may contribute to bleeding and overwhelming infections [see Warnings and Precautions (5.1) and Adverse Reactions (6)]. Monitor blood counts weekly for at least 6 weeks after each dose. Adjust dosage based on nadir blood counts from the prior dose [see Dosage and Administration (2.1)]. Do not administer a repeat course of carmustine for injection until blood counts recover.
Pulmonary Toxicity
C armustine for injection causes dose-related pulmonary toxicity. Patients receiving greater than 1,400 mg/m2 cumulative dose are at significantly higher risk than those receiving less. Delayed pulmonary toxicity can occur years after treatment, and can result in death, particularly in patients treated in childhood [see Adverse Reactions (6) and Use in Specific Populations (8.4)].

2 Dosage And Administration
- Recommended Dosage: As a single agent, 150 mg/m2 to 200 mg/m2 carmustine for injection intravenously every 6 weeks as a single-dose or divided into daily injections such as 75 mg/m2 to 100 mg/m2 on 2 successive days. Adjust dose for combination therapy or in patients with reduced bone marrow reserve. (
2.1 )- Administer reconstituted solution only as a slow intravenous infusion over at least 2 hours. (
2.2 )2.1 Dosage
The recommended dose of carmustine for injection as a single agent in previously untreated patients is 150 mg/m2 to 200 mg/m2 intravenously every 6 weeks. Administer as a single-dose or divided into daily injections such as 75 mg/m2 to 100 mg/m2 on two successive days. Lower the dose when carmustine for injection is used with other myelosuppressive drugs or in patients in whom bone marrow reserve is depleted. Administer carmustine for injection, for the duration according to the established regimen. Premedicate each dose with anti-emetics.
Adjust doses subsequent to the initial dose according to the hematologic response of the patient to the preceding dose. The following schedule is suggested as a guide to dosage adjustment:
Nadir After Prior Dose
Percentage of Prior Dose to be Given
Leukocytes/mm3
Platelets/mm3
> 4,000
> 100,000
100%
3,000 to 3,999
75,000 to 99,999

2,000 to 2,999
25,000 to 74,999
70%
< 2,000
< 25,000
50%
The hematologic toxicity can be delayed and cumulative. Monitor blood counts weekly. Do not administer a repeat course of carmustine for injection until circulating blood elements have returned to acceptable levels (platelets above 100 Gi/L, leukocytes above 4 Gi/L and absolute neutrophil count above 1 Gi/L). The usual interval between courses is 6 weeks.
Evaluate renal function prior to administration and periodically during treatment. For patients with compromised renal function, monitor for toxicity more frequently. Discontinue carmustine for injection if the creatinine clearance is less than 10 mL/min. Do not administer carmustine for injection to patients with compromised renal function. Monitor transaminases and bilirubin periodically during treatment [see Adverse Reactions (6)].
2.2 Preparation and Administration ofIntravenous Solution
- Dissolve carmustine for injection with 3 mL of the supplied sterile diluent (Dehydrated Alcohol Injection, USP).
- Aseptically add 27 mL Sterile Water for Injection, USP.
- Each mL of resulting solution contains 3.3 mg of carmustine for injection in 10% ethanol. Such solutions should be protected from light.
- The reconstituted solution is a clear, colorless to yellowish solution.
- Once reconstituted, the solution must be further diluted with Sodium Chloride Injection, USP or 5% Dextrose Injection, USP.
- Examine reconstituted vials for crystal formation prior to use. If crystals are observed, they may be re-dissolved by warming the vial to room temperature with agitation.
- Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
- After reconstitution as recommended, carmustine for injection is stable for 24 hours under refrigeration 2° to 8°C, (36° to 46°F) in glass container. Examine reconstituted vials for crystal formation prior to use. If crystals are observed, they may be redissolved by warming the vial to room temperature with agitation.
- Vials reconstituted as directed and further diluted with 500 mL Sodium Chloride Injection, USP or 5% Dextrose Injection, USP, in glass or polypropylene containers to a concentration of 0.2 mg/mL, should be stored at room temperature, protected from light and utilized within 8 hours. These solutions are also stable 24 hours under refrigeration 2° to 8°C, (36° to 46°F) and an additional 6 hours at room temperature protected from light.
- Administer reconstituted solution by slow intravenous infusion over at least two hours. Administration of carmustine for injection over a period of less than two hours can lead to pain and burning at the site of injection. Monitor the injected area during the administration. The rate of administration of the intravenous infusion should not be more than 1.66 mg/m2/min.
- See Section 16.2 for important instructions on the storage and handling of the injection. Carmustine for injection is a cytotoxic drug. Follow applicable special handling and disposal procedures.1
- The lyophilized dosage formulation contains no preservatives and is not intended for use as a multiple dose vial.
Accidental contact of reconstituted carmustine for injection with the skin has caused transient hyperpigmentation of the affected areas. Wear impervious gloves to minimize the risk of dermal exposure impervious gloves when handling vials containing carmustine for injection. Immediately wash the skin or mucosa thoroughly with soap and water if carmustine for injection lyophilized material or solution contacts the skin or mucosa1.
3 Dosage Forms And Strengths

- Hypersensitivity. (
4 )
5 Warnings And Precautions
- Administration Reactions: Extravasation may occur; monitor infusion site closely during administration. (
5.3 )- Carcinogenicity: Potentially carcinogenic to humans. Monitor patient periodically for such signs and apprise the patient of the symptoms for which they need to seek medical help. (
5.4 )- Ocular Toxicity: Has occurred when administered via unapproved intraarterial intracarotid route. (
5.5 )- Embryo-Fetal toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to avoid pregnancy. (
5.6 )5.1 Myelosuppression
Bone marrow toxicity is a dose-limiting, common and severe toxic effect of carmustine for injection occurring 4 to 6 weeks after drug administration (thrombocytopenia occurs at about 4 weeks post-administration persisting for 1 to 2 weeks; leukopenia occurs at 5 to 6 weeks after a dose of carmustine for injection persisting for 1 to 2 weeks; thrombocytopenia is generally more severe than leukopenia; anemia is less frequent and less severe compared to thrombocytopenia and/or leukopenia) Complete blood count should therefore be monitored weekly for at least six weeks after a dose. Repeat doses of carmustine for injection should not be given more frequently than every six weeks. The bone marrow toxicity of carmustine for injection is cumulative and therefore the dosage adjustment must be considered on the basis of nadir blood counts from prior dose [see Adverse Reactions (6)]. Greater myelotoxicity (e.g., leukopenia and neutropenia) has been reported when carmustine was combined with cimetidine [see Drug Interactions (7)].
5.2 Pulmonary Toxicity
Cases of fatal pulmonary toxicity with carmustine for injection have been reported. Pulmonary toxicity characterized by pulmonary infiltrates and/or fibrosis has been reported to occur from 9 days to 43 months after treatment with carmustine for injection and related nitrosoureas. Pulmonary toxicity from carmustine for injection is dose-related. Patients receiving greater than 1,400 mg/m2 cumulative dose are at significantly higher risk than those receiving less. However, there have been reports of pulmonary fibrosis in patients receiving lower total doses. Interstitial fibrosis (with lower doses) occurred rarely. Additionally, delayed onset pulmonary fibrosis occurring up to 17 years after treatment has been reported in patients who received carmustine for injection (in cumulative doses ranging from 770 mg/m2 to 1,800 mg/m2 combined with cranial radiotherapy for intracranial tumors) in childhood and early adolescence. Other risk factors include past history of lung disease and duration of treatment. Baseline pulmonary function studies should be conducted along with frequent pulmonary function tests during treatment. Patients with a baseline below 70% of the predicted forced vital capacity (FVC) or carbon monoxide diffusing capacity (DLCO) are particularly at risk.
5.3 Administration Reactions
Injection site reactions may occur during the administration of carmustine for injection. Rapid intravenous infusion of carmustine for injection may produce intensive flushing of the skin and suffusion of the conjunctiva within 2 hours, lasting about 4 hours. It is also associated with burning at the site of injection although true thrombosis is rare. Given the possibility of extravasation, close monitoring of the infusion site for possible infiltration during drug administration is recommended. A specific treatment for extravasation reactions is unknown at this time.
5.4 Carcinogenicity
Long-term use of nitrosoureas, such as carmustine for injection, has been reported to be associated with the development of secondary malignancies. Carmustine was carcinogenic when administered to laboratory animals [see Nonclinical Toxicity (13.1)]. Nitrosourea therapy, such as carmustine for injection, has carcinogenic potential in humans. Patients treated with carmustine for injection should be monitored long-term for development of second malignancies.
5.5 Ocular Toxicity
Carmustine for injection has been administered through an intraarterial intracarotid route; this procedure is investigational and has been associated with ocular toxicity. Safety and effectiveness of the intra-arterial route have not been established.
5.6 Embryo-Fetal Toxicity
Carmustine was embryotoxic in rats and rabbits and teratogenic in rats when given in doses lower than the maximum cumulative human dose based on body surface area. There are no adequate and well-controlled studies in pregnant women. Advise pregnant women of the potential risk to the fetus [see Use in Specific Populations (8.1, 8.3)]. Advise females of reproductive potential to use highly effective contraception during and after treatment with carmustine for injection, for at least 6 months after therapy. Advise males of reproductive potential to use effective contraception during and after treatment with carmustine for injection, for at least 3 months after therapy [see Use in Specific Populations (8.1, 8.3)].
6 Adverse Reactions

7 Drug Interactions
- Cimetidine: Increased myelosuppression with concomitant use. (
7.1 )- Phenobarbital: Induces carmustine metabolism, reducing exposure. May lead to reduced efficacy. (
7.1 )- Phenytoin: Carmustine for injection may reduce the efficacy of phenytoin. (
7.2 )7.1 Effects of Other Drugs on Carmustine for Injection
Cimetidine
Greater myelosuppression (e.g., leukopenia and neutropenia) has been reported when oral cimetidine has been co-administered with carmustine. Consider alternative drugs to cimetidine.
Phenobarbital
Phenobarbital induces the metabolism of carmustine and may compromise antitumor activity of carmustine for injection. Consider alternative drugs to phenobarbital.
7.2 Effects of Carmustine for Injection onOther Drugs
Phenytoin
Carmustine for injection when co-administered with phenytoin may reduce phenytoin serum concentrations. Consider alternative drugs to phenytoin.
8 Use In Specific Populations
- Lactation: Advise lactating females not to breastfeed. (
8.2 )8.1 Pregnancy
Risk Summary
Carmustine for injection can cause fetal harm when administered to a pregnant woman based on the mechanism of action [see Clinical Pharmacology (12.1)] and findings in animals [see Data]. Limited available data with carmustine for injection use in pregnant women are insufficient to inform a drug-associated risk of major birth defects and miscarriage. Carmustine was embryotoxic in rats and rabbits and teratogenic in rats (thoracoabdominal closure, neural tube, and eye defects and malformations of the skeletal system of the fetus) when given in doses lower than the maximum cumulative human dose based on body surface area. Consider the benefits and risks of carmustine for injection, for the mother and possible risks to the fetus when prescribing carmustine for injection to a pregnant woman.
Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Data
Animal Data
Intraperitoneal (IP) administration of carmustine to pregnant rats 14 days prior to mating and during the period of organogenesis at cumulative doses ≥ 26 mg/kg (158 mg/m2), approximately 0.1 times the maximum cumulative human dose of 1,400 mg/m2, resulted in pre-implantation loss, increased resorptions (including completely resorbed litters), and reduced the number of live births in the presence of maternal toxicity.
Carmustine administered IP to pregnant rats during the period of organogenesis at cumulative doses ≥ 4 mg/kg (24 mg/m2), approximately 0.02 times the maximum cumulative human dose based on a mg/m2 basis, resulted in reduced fetal weight and various malformations, which included thoracoabdominal closure defects, neural tube defects, and eye defects, including microphthalmia/anophthalmia, and skeletal anomalies in the skull, sternebra, vertebrae and ribs, and reduced skeletal ossification) in the presence of maternal toxicity. Embryo-fetal death was observed at cumulative doses ≥ 8 mg/kg (48 mg/m2), approximately 0.03 times the maximum cumulative human dose on a mg/m2 basis. Intravenous (IV) administration of carmustine to rats at a cumulative dose of 50 mg/kg (300 mg/m2), approximately 0.2 times the maximum cumulative human dose on a mg/m2 basis, during the last quarter of pregnancy resulted in the death of offspring within 4 months. Carmustine administered IV to rabbits during the period of organogenesis resulted in spontaneous abortions in mothers and growth defects in the fetus, mainly at cumulative doses ≥ 13 mg/kg (156 mg/m2), approximately 0.1 times the maximum cumulative human dose on a mg/m2 basis.
8.2 Lactation
Risk Summary
There is no information regarding the presence of carmustine in human milk, the effects on the breastfed infant, or the effects on milk production. Because many drugs are excreted in human milk and because of the potential for serious adverse events (e.g., carcinogenicity and myelosuppression) in nursing infants, nursing should be discontinued while taking carmustine for injection.
8.3 Females and Males ofReproductive Potential
Contraception
Advise female patients to avoid pregnancy during treatment with carmustine for injection because of the risk of fetal harm [see Use in Specific Populations (8.1)].
Advise female patients of reproductive potential to use highly effective contraception during and for up to six months after completion of treatment.
Advise males with female sexual partners of reproductive potential to use effective contraception during carmustine for injection treatment and for at least three months after the final dose of carmustine for injection [see Nonclinical Toxicology (13.1)].
Infertility
Based on nonclinical findings, male fertility may be compromised by treatment with carmustine for injection [see Nonclinical Toxicology (13.1)].
8.4 Pediatric Use
Safety and effectiveness in children have not been established. Delayed onset pulmonary fibrosis occurring up to 17 years after treatment has been reported in a long-term study of patients who received carmustine for injection in childhood and early adolescence (1 to 16 years). Eight out of the 17 patients (47%) who survived childhood brain tumors, including all the 5 patients initially treated at less than 5 years of age, died of pulmonary fibrosis [see Adverse Reactions (6.1)].
8.5 Geriatric Use
Clinical studies of carmustine for injection 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, dose selection for an elderly patient should be cautious, usually starting at the low end of the dose range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Carmustine for injection and its metabolites are known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and renal function should be monitored.
10 Overdosage
The main result of overdose is myeloablation. No proven antidotes have been established for carmustine for injection overdosage.
11 Description
The active ingredient in carmustine for injection, USP is a nitrosourea with the chemical name 1,3-bis(2-chloroethyl)-1-nitrosourea and a molecular weight of 214.05 g/mol. The drug product is supplied as sterile lyophilized pale yellow flakes or a congealed mass, and it is highly soluble in alcohol and lipids, and poorly soluble in water. Carmustine for injection is administered by intravenous infusion after reconstitution, as recommended.
The molecular formula of carmustine is C5H9Cl2N3O2 and the structural formula of carmustine is:
Carmustine for injection, USP is available in 100 mg single-dose vials of lyophilized material. Sterile diluent for constitution of carmustine for injection, USP is co-packaged with the active drug product for use in constitution of the lyophile. The diluent is supplied in a vial containing 3 mL of dehydrated alcohol injection, USP.
12 Clinical Pharmacology
12.1 Mechanism of Action
The mechanism of action of carmustine is not fully understood. While carmustine alkylates DNA and RNA, it is not cross-resistant with other alkylators. As with other nitrosoureas, it may also inhibit several key enzymatic processes by carbamoylation of amino acids in proteins. The metabolites may contribute to antitumor activity and toxicities of carmustine.
12.2 Pharmacodynamics
The exposure-response relationship for efficacy or safety is unknown.
12.3 Pharmacokinetics
Distribution
Carmustine crosses the blood-brain barrier. Levels of radioactivity in the CSF are greater than or equal to 50% of those measured concurrently in plasma.
Elimination
Following a short intravenous infusion, the reported elimination half-life ranges from 15 minutes to 75 minutes.
Metabolism
Carmustine may be inactivated through denitrosation reactions catalyzed by both cytosolic and microsomal enzymes, including NADPH and glutathione-S-transferase.
Excretion
Approximately 60% to 70% of a total dose is excreted in the urine within 96 hours. Approximately 10% is eliminated as respiratory CO2.
13 Nonclinical Toxicology
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Carmustine is carcinogenic in rats and mice, producing a marked increase in tumor incidence in doses approximating those employed clinically. Nitrosourea therapy does have carcinogenic potential in humans [see Adverse Reactions (6.1)].
Carmustine was mutagenic and clastogenic in multiple in vitro and in vivo genetic toxicology studies.
Male rats treated with carmustine at cumulative doses ≥ 36 mg/kg (216 mg/m2), approximately 0.15 times the maximum cumulative human dose on a mg/m2 basis, showed decreases in reproductive potential when mated with untreated female rats (e.g., decreased implantations, increased resorption rate, and a decrease in viable fetuses).
