Carmustine causes suppression of marrow function (including thrombocytopenia and leukopenia), which may contribute to bleeding and overwhelming infections. Monitor blood counts weekly for at least 6 weeks after each dose. Adjust dosage based on nadir blood counts from the prior dose. Do not administer a repeat course of carmustine until blood counts recover.
Carmustine 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.
Dosage guidance:
Clinical considerations: Carmustine (IV) is associated with a high emetic potential; antiemetics are recommended to prevent nausea and vomiting (Ref). Platelet counts should be >100,000/mm3, ANC >1,000/mm3, and leukocytes >4,000/mm3 prior to a repeat course. Repeat courses should not be administered more frequently than every 6 weeks. Refer to the protocol or institutional guidance for additional details of off-label dosing.

Glioma, recurrent (off-label dose): IV: 80 mg/m2 on days 1, 2, and 3 every 8 weeks for a maximum of 6 cycles (Ref).
Glioma, malignant, newly diagnosed (off-label dose): IV: 200 mg/m2 every 8 weeks (up to a maximum cumulative dose of 1,500 mg/m2) (Ref).
Wafer implants: Note: Optimal antiseizure therapy should be initiated prior to surgery.
Glioma, newly diagnosed high-grade: Implantation (wafer): 8 wafers (7.7 mg each) implanted intracranially into the resection cavity (total dose 61.6 mg); should the size and shape not accommodate 8 wafers, the maximum number of wafers feasible (up to 8) should be placed.
Glioblastoma, recurrent: Implantation (wafer): 8 wafers (7.7 mg each) implanted intracranially into the resection cavity (total dose 61.6 mg); should the size and shape not accommodate 8 wafers, the maximum number of wafers feasible (up to 8) should be placed.

American Society of Clinical Oncology guidelines for appropriate systemic therapy dosing in adults with cancer with a BMI ≥30 kg/m2 (Note: Excludes hematopoietic cell transplantation dosing): Utilize patient's actual body weight for calculation of BSA- or weight-based dosing; manage regimen-related toxicities in the same manner as for patients with a BMI <30 kg/m2; if a dose reduction is utilized due to toxicity, may consider resumption of full, weight-based dosing (or previously tolerated dose level) with subsequent cycles only if dose escalations are allowed in the prescribing information, if contributing underlying factors (eg, hepatic or kidney impairment) are sufficiently resolved, AND if performance status has markedly improved or is considered adequate (Ref).
American Society for Blood and Marrow Transplantation practice guideline committee position statement on conditioning chemotherapy dosing in obesity: Utilize actual body weight for calculation of BSA in carmustine dosing for hematopoietic cell transplant conditioning regimens in adult patients weighing ≤120% of their ideal body weight (IBW). In patients weighing >120% IBW, utilize adjusted body weight 25% (ABW25) to calculate BSA (Ref).
ABW25: Adjusted wt (kg) = Ideal body weight (kg) + 0.25 [actual wt (kg) - ideal body weight (kg)]
Carmustine IV:
Hematologic toxicity: Based on nadir counts with previous dose (Ref). IV:
If leukocytes ≥3,000/mm3 and platelets ≥75,000/mm3: Administer 100% of carmustine dose.
If leukocytes 2,000 to 2,999/mm3 or platelets 25,000 to 74,999/mm3: Reduce dose to 70% of usual carmustine dose.
If leukocytes <2,000/mm3 or platelets <25,000/mm3: Reduce dose to 50% of usual carmustine dose.
Pulmonary toxicity (signs/symptoms or decreased carbon monoxide diffusing capacity): Consider initiating systemic corticosteroid therapy (eg, prednisone) and consider discontinuing carmustine (Ref).
Carmustine wafer:
Intracranial hypertension (related to brain edema, inflammation, or necrosis of brain tissue surrounding resection): May require re-operation to remove wafers (or remnants) for refractory cases.
Refer to adult dosing.
(For additional information see "Carmustine: Pediatric drug information")
Dosage guidance:
Safety: Children are at increased risk for pulmonary toxicity due to carmustine; weigh risk versus benefit before use. Carmustine IV is associated with a moderate or high emetic potential (dose related); antiemetics are recommended to prevent nausea and vomiting (Ref). Refer to individual protocols; dosing and frequency may vary.

Concerns related to adverse effects:
• Bone marrow suppression: Carmustine IV causes bone marrow suppression, primarily thrombocytopenia (which may lead to bleeding) and leukopenia (which may cause infection). Hematologic toxicity is dose-limiting, may be severe, and is generally delayed and cumulative; thrombocytopenia is usually more severe than leukopenia. Myelosuppression generally occurs 4 to 6 weeks after administration; thrombocytopenia occurs at ~4 weeks and persists for 1 to 2 weeks; leukopenia occurs at 5 to 6 weeks and persists for 1 to 2 weeks. Anemia may occur (less common and less severe than leukopenia or thrombocytopenia).
• Hepatic: Reversible increases in transaminases, bilirubin, and alkaline phosphatase have been reported (rare) with the IV formulation.
• Infusion-site reactions: Rapid infusions are associated with skin flushing and conjunctiva redness (onset: <2 hours; duration ~4 hours). Carmustine is also associated with injection-site burning and local tissue reactions, including swelling, pain, erythema, and necrosis, have been reported. Monitor infusion site closely for infiltration or injection-site reactions. Avoid extravasation.
• Intracranial hypertension: Brain edema has been reported in patients with newly diagnosed glioma receiving wafer implants, including one report of intracranial mass effect unresponsive to corticosteroids that led to brain herniation. Intracranial hypertension may be related to brain edema, inflammation, or necrosis of brain tissue surrounding resection.
• Meningitis: Cases of meningitis have occurred in patients with recurrent glioma receiving wafer implants. Two cases were bacterial (one patient required removal of implants 4 days after implantation and the other developed meningitis following reoperation for recurrent tumor). Another case was determined to be chemical meningitis and resolved with corticosteroids.
• Ocular toxicity: Investigational administration (intraarterial intracarotid route [not an approved route]) has been associated with ocular toxicity.
• Pulmonary toxicity: Carmustine IV is associated with dose-related pulmonary toxicity; patients receiving cumulative doses >1,400 mg/m2 are at significantly higher risk. Delayed onset of pulmonary fibrosis may occur years after treatment (may be fatal), particularly in children. Pulmonary toxicity has occurred in children and adolescents up to 17 years after treatment; this occurred in ages 1 to 16 for the treatment of intracranial tumors; cumulative doses ranged from 770 to 1,800 mg/m2 (in combination with cranial radiotherapy). Pulmonary toxicity is characterized by pulmonary infiltrates and/or fibrosis and has been reported from 9 days to 43 months after nitrosourea treatment (including carmustine). Although pulmonary toxicity generally occurs in patients who have received prolonged treatment, pulmonary fibrosis has been reported with cumulative doses below 1,400 mg/m2. Interstitial fibrosis at lower doses has occurred (rare). In addition to high cumulative doses, other risk factors for pulmonary toxicity include history of lung disease and baseline predicted forced vital capacity (FVC) or carbon monoxide diffusing capacity (DLCO) <70%. For high-dose treatment (transplant; off-label dose), acute lung injury may occur ~1 to 3 months post transplant; advise patients to contact their transplant physician for dyspnea, cough, or fever.
• Renal: Renal failure, progressive azotemia, and decreased kidney size have been reported.
• Secondary malignancies: Long-term IV use is associated with the development of secondary malignancies (acute leukemias and bone marrow dysplasias).
• Seizures: Seizures occurred in patients who received carmustine wafer implants, including new or worsening (treatment-emergent) seizures. Just over half of treatment-emergent seizures occurred within 5 days of surgery; the median onset of first new or worsened post-operative seizure was 4 days.
• Wound healing impairment: Impaired neurosurgical wound healing, including wound dehiscence, delayed healing, and subdural, subgaleal, or wound effusions may occur with carmustine wafer implant treatment; cerebrospinal fluid leaks have also been reported.
Special populations:
• Pediatric: Children are at higher risk of delayed pulmonary toxicity with the IV formulation.
Dosage form specific issues:
• Injection: Diluent may contain ethanol or propylene glycol (formulation-dependent; refer to manufacturer's labeling).
• Wafer: Monitor closely for known craniotomy-related complications (seizure, intracranial infection, abnormal wound healing, brain edema). Wafer migration may occur; avoid communication between the resection cavity and the ventricular system to prevent wafer migration; communications larger than the wafer should be closed prior to implantation; wafer migration into the ventricular system may cause obstructive hydrocephalus.

Vaccines (Live): Immunosuppressants (Cytotoxic Chemotherapy) may increase adverse/toxic effects of Vaccines (Live). Specifically, the risk of vaccine-associated infection may be increased. Vaccines (Live) may decrease therapeutic effects of Immunosuppressants (Cytotoxic Chemotherapy). Risk X: Avoid
Vaccines (Non-Live/Inactivated/Non-Replicating): Immunosuppressants (Cytotoxic Chemotherapy) may decrease therapeutic effects of Vaccines (Non-Live/Inactivated/Non-Replicating). Management: Give non-live/inactivated/non-replicating vaccines at least 2 weeks prior to starting chemotherapy when possible. Patients vaccinated less than 14 days before or during chemotherapy should be revaccinated at least 3 months after therapy is complete. Risk D: Consider Therapy Modification
Yellow Fever Vaccine: Immunosuppressants (Cytotoxic Chemotherapy) may decrease therapeutic effects of Yellow Fever Vaccine. Immunosuppressants (Cytotoxic Chemotherapy) may increase adverse/toxic effects of Yellow Fever Vaccine. Specifically, the risk of vaccine-associated infection may be increased. Risk X: Avoid
Zoster Vaccine (Live/Attenuated): Immunosuppressants (Cytotoxic Chemotherapy) may increase adverse/toxic effects of Zoster Vaccine (Live/Attenuated). Specifically, the risk of vaccine-associated infection may be increased. Immunosuppressants (Cytotoxic Chemotherapy) may decrease therapeutic effects of Zoster Vaccine (Live/Attenuated). Risk X: Avoid
Evaluate pregnancy status prior to therapy. Patients who could become pregnant should use highly effective contraceptives during and for at least 6 months following treatment with carmustine. Patients with partners who could become pregnant should use highly effective contraceptives during and for at least 3 months following treatment with carmustine. Carmustine may impair male fertility; advise males of potential risk of infertility.
Based on the mechanism of action, and data from animal reproduction studies, in utero exposure to carmustine may cause fetal harm. Outcome information related to the use of carmustine in pregnancy is limited (NTP 2013).
It is not known if carmustine is present in breast milk.
Due to the potential for serious adverse reactions in the breastfed infant, the manufacturer recommends breastfeeding be discontinued during treatment with the injection and for at least 7 days after implantation of the wafer.
Verify pregnancy status prior to therapy in patients who could become pregnant.
Injection: CBC with differential and platelet count (weekly for at least 6 weeks after each dose), pulmonary function tests (FVC, DLCO; at baseline and frequently during treatment), LFTs (transaminases and bilirubin; periodically during treatment), renal function tests (periodically). Monitor BP and vital signs during administration. Monitor infusion site for possible infiltration or injection-site reactions. Monitor for signs/symptoms of pulmonary toxicity and for development of secondary malignancies.
Wafer: Monitor postoperatively for seizures, impaired neurosurgical wound healing, and signs/symptoms of meningitis, CNS infection, and obstructive hydrocephalus; monitor closely for intracranial hypertension related to brain edema, inflammation, or necrosis of brain tissue surrounding resection.
The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.
Carmustine interferes with the normal function of DNA and RNA by alkylation and cross-linking the strands of DNA and RNA, and by possible protein modification; may also inhibit enzyme processes by carbamylation of amino acids in protein.
