Teniposide


General


Pronunciation

(ten i POE side)


Brand Names: U.S.

  • Vumon [DSC]

Indications


Use: Labeled Indications

Acute lymphoblastic leukemia, refractory: Treatment of refractory childhood acute lymphoblastic leukemia (ALL) in combination with other chemotherapy


Contraindications


Hypersensitivity to teniposide, polyoxyl 35/polyoxyethylated castor oil (Cremophor EL), or any component of the formulation


ALERT: U.S. Boxed Warning

Experienced physician:

Teniposide is a cytotoxic drug. Administer under the supervision of a qualified health care provider experienced in the use of cancer chemotherapeutic agents. Appropriate management of therapy and complications is possible only when adequate treatment facilities are readily available.

Bone marrow suppression:

Severe myelosuppression with resulting infection or bleeding may occur.

Hypersensitivity reactions:

Hypersensitivity reactions, including anaphylaxis-like symptoms, may occur with initial dosing or with repeated exposure to teniposide. Epinephrine, with or without corticosteroids and antihistamines, has been employed to alleviate hypersensitivity reaction symptoms.


Dosing and Administration


Dosing: Adult

Note: Patients with Down syndrome and leukemia may be more sensitive to the myelosuppressive effects; administer the first course at half the usual dose and adjust dose in subsequent cycles upward based on degree of toxicities (myelosuppression and mucositis) in the previous course(s).

Acute lymphoblastic leukemia (ALL) consolidation treatment (off-label use; combination chemotherapy): IV: 165 mg/m2/dose days 1, 4, 8, and 11 of alternating consolidation cycles (Linker, 1991)


Dosing: Pediatric

Note: Patients with Down syndrome and leukemia may be more sensitive to the myelosuppressive effects; administer the first course at half the usual dose and adjust dose in subsequent cycles upward based on degree of toxicities (myelosuppression and mucositis) in the previous course(s).

Acute lymphoblastic leukemia (ALL), refractory (combination chemotherapy): IV: 165 mg/m2 twice weekly for 8 to 9 doses (in combination with cytarabine) or 250 mg/m2 weekly for 4 to 8 weeks (in combination with vincristine and prednisone)


Dosing: Renal Impairment

There are no specific dosage adjustments provided in the manufacturer 's labeling (has not been studied). However, dosage adjustment may be necessary in patients with significant renal impairment.


Dosing: Hepatic Impairment

There are no specific dosage adjustments provided in the manufacturer 's labeling (has not been studied). However, dosage adjustment may be necessary in patients with significant hepatic impairment.


Reconstitution

Hazardous agent; use appropriate precautions for handling and disposal (NIOSH 2014 [group 1]). Precipitation may occur at any concentration. Teniposide must be diluted with either D5W or NS solutions to a final concentration of 0.1, 0.2, 0.4, or 1 mg/mL. Solutions should be prepared in non-DEHP-containing containers such as glass or polyolefin containers. The use of polyvinyl chloride (PVC) containers is not recommended. Because precipitation may occur at any concentration, the manufacturer recommends administrating as soon as possible after preparation. Teniposide contains N,N-dimethylacetamide, which is incompatible with many closed system transfer devices (CSTDs); the plastic components of CSTDs may dissolve and result in subsequent leakage and potential infusion of dissolved plastic into the patient (ISMP [Smetzer 2015]).


Administration

IV; must be administered slowly (over at least 30-60 minutes); do not administer by rapid IV injection. Administer through non-DEHP-containing administration sets. Incompatible with heparin; flush infusion line with D5W or NS before and after infusion. Precipitation may occur at any concentration; administer as soon as possible after preparation; inspect solution prior to administration. Observe patient continuously for at least the first 60 minutes after the start of the infusion, observe frequently thereafter. Stop infusion for signs of anaphylaxis (may require treatment with epinephrine, corticosteroids, antihistamines, pressors, or volume expanders); discontinue for clinically significant hypotension during infusion; if infusion is restarted after being withheld for hypotension, reinitiate at a slower infusion rate.

Teniposide contains N, N-dimethylacetamide, which is incompatible with many closed system transfer devices (CSTDs); the plastic components of CSTDs may dissolve and result in subsequent leakage and potential infusion of dissolved plastic into the patient (ISMP [Smetzer 2015]).

Hazardous agent; use appropriate precautions for handling and disposal (NIOSH 2014 [group 1]).


Storage

Store ampuls in refrigerator at 2 � �C to 8 � �C (36 � �F to 46 � �F). Protect from light. Solutions diluted for infusion in D5W or NS to a concentration of 0.1, 0.2, or 0.4 mg/mL are stable at room temperature for up to 24 hours after preparation; solutions diluted to 1 mg/mL should be used within 4 hours of preparation. Because precipitation may occur at any concentration, the manufacturer recommends administrating as soon as possible after preparation. Use appropriate precautions for handling and disposal. Do not refrigerate solutions prepared for infusion.

Warnings/Precautions


Special Populations: Hepatic Function Impairment

There appears to be an association between an increase in serum alkaline phosphatase or gamma glutamyl-transpeptidase and a decrease in plasma clearance of teniposide.


Warnings/Precautions

Concerns related to adverse effects:

- Bone marrow suppression: [US Boxed Warning]: Severe myelosuppression resulting in infection or bleeding may occur; may be dose-limiting; monitor blood counts during and after treatment.

- Extravasation: Teniposide is considered an irritant (Perez Fidalgo, 2012). For IV use only; ensure proper catheter/needle position prior to infusion; monitor infusion site; may cause local tissue necrosis and/or thrombophlebitis if extravasation occurs.

- Hypersensitivity reactions: [US Boxed Warning]: Hypersensitivity reactions, including anaphylaxis-like reactions, have been reported; may occur with initial dosing or with repeated exposure to teniposide. Epinephrine, with or without corticosteroids and antihistamines, has been employed to alleviate hypersensitivity reaction symptoms. Hypersensitivity reactions may include bronchospasm, dyspnea, hypertension, hypotension, tachycardia, flushing, chills, fever, or urticaria. Monitor closely during infusion (observe continuously for first 60 minutes, frequently thereafter). Stop infusion for signs of anaphylaxis; immediate treatment for anaphylactic reaction should be available during administration (may require treatment with epinephrine, corticosteroids, antihistamines, pressors, or volume expanders). Patients experiencing prior hypersensitivity are at risk for recurrence; re-treat only if the potential benefit outweighs the risk of hypersensitivity; premedication (with corticosteroids and antihistamines) is recommended for re-treatment.

- Hypotension: Hypotension may occur with rapid infusion; infuse slowly over at least 30 to 60 minutes; discontinue for clinically significant hypotension. If infusion is restarted after being withheld for hypotension, reinitiate at a slower infusion rate.

- Toxicity with high doses: Acute CNS depression, hypotension and metabolic acidosis have been reported; these events occurred in patients who received high-dose teniposide (investigation protocol) and were premedicated with antiemetics, which along with the alcohol content of teniposide, may have contributed to the CNS depression.

Disease-related concerns:

- Hepatic impairment: Use with caution; may require dosage reduction in patients with significant impairment.

- Renal impairment: Use with caution; may require dosage reduction in patients with significant impairment.

Concurrent drug therapy issues:

- Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

- Down syndrome: Patients with Down syndrome and leukemia may be more sensitive to the myelosuppressive effects; reduced initial doses are recommended.

- Hypoalbuminemia: Since teniposide is highly bound to plasma proteins, carefully monitor patients with hypoalbuminemia.

Dosage form specific issues:

- Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol; large amounts of benzyl alcohol ( ≥99 mg/kg/day) have been associated with a potentially fatal toxicity ( "gasping syndrome " �) in neonates; the "gasping syndrome " � consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP [Inactive" 1997]; CDC, 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors, 2001); avoid or use dosage forms containing benzyl alcohol with caution in neonates. See manufacturer 's labeling.

- Dehydrated alcohol: Product contains about 43% alcohol.

- Dimethylacetamide (DMA): Teniposide contains N,N-dimethylacetamide, which is incompatible with many closed system transfer devices (CSTDs); the plastic components of CSTDs may dissolve and result in subsequent leakage and potential infusion of dissolved plastic into the patient (ISMP [Smetzer 2015]).

- Polyoxyl 35/polyoxyethylated castor oil: Contains polyoxyl 35/polyoxyethylated castor oil (Cremophor EL), which is associated with hypersensitivity reactions.

Special handling:

- Hazardous agent: Use appropriate precautions for handling and disposal (NIOSH 2014 [group 1]).

Other warnings/precautions:

- Experienced physician: [US Boxed Warning]: Should be administered under the supervision of an experienced cancer chemotherapy physician. Appropriate management of therapy and complications is possible only when adequate treatment facilities are readily available.


Pregnancy Risk Factor

D


Pregnancy Considerations

Adverse effects were observed in animal reproduction studies. May cause fetal harm if administered during pregnancy. Women of childbearing potential should avoid becoming pregnant during teniposide treatment.


Actions


Pharmacology

Teniposide does not inhibit microtubular assembly; it has been shown to delay transit of cells through the S phase and arrest cells in late S or early G2 phase, preventing cells from entering mitosis. Teniposide is a topoisomerase II inhibitor, and appears to cause DNA strand breaks by inhibition of strand-passing and DNA ligase action.


Distribution

Vdss: Children: 3 to 11 L/m2; Adults: 8 to 44 L/m2; mainly into liver, kidneys, small intestine, and adrenals; limited distribution into CSF <1%


Metabolism

Extensively hepatic


Excretion

Urine (44%, 4% to 12% as unchanged drug); feces ( ≤10%)

Clearance: Renal: 10% of total body clearance


Half-Life Elimination

Children: 5 hours


Protein Binding

>99%; primarily albumin


Patient and Family Education


Patient Education

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

- Patient may experience mouth sores or hair loss. Have patient report immediately to prescriber signs of infection, signs of liver problems (dark urine, feeling tired, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or yellow skin or eyes), signs of kidney problems (urinary retention, blood in urine, change in amount of urine passed, weight gain), tachycardia, arrhythmia, shortness of breath, severe headache, severe dizziness, passing out, flushing, severe abdominal pain, severe nausea, vomiting, severe diarrhea, bruising, bleeding, loss of strength and energy, burning or numbness feeling, severe injection site pain or irritation, or confusion (HCAHPS).

- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
