A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Teniposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent cells from entering into the mitotic phase of the cell cycle, and lead to cell death. Teniposide acts primarily in the G2 and S phases of the cycle.
Teniposide is a Topoisomerase Inhibitor. The mechanism of action of teniposide is as a Topoisomerase Inhibitor.

4.3 Drug Warning

Since patients with Down's syndrome and leukemia may be particularly sensitive to myelosuppressive chemotherapy, initial dosage of teniposide should be reduced in such patients.

McEvoy, G.K. (ed.). American Hospital Formulary Service- Drug Information 2004. Bethesda, MD: American Society of Health-System Pharmacists, Inc. 2004 (Plus Supplements)., p. 1139


There currently is insufficient experience with teniposide therapy in patients with impaired renal and/or hepatic function to make specific recommendations for dosage adjustment. However, the possibility that adjustment in teniposide dosage may be necessary in such patients should be considered.

The major and dose-limiting adverse effect of teniposide is hematologic toxicity. Myelosuppression, which is dose related, can be severe when teniposide is used in combination with other chemotherapeutic agents for the treatment of acute lymphocytic leukemia (ALL). Early onset of profound myelosuppression with delayed recovery can be expected when using the doses and schedules of teniposide necessary for the treatment of refractory ALL, since bone marrow hypoplasia is a desired endpoint of therapy. Severe myelosuppression with resulting infection and bleeding may occur in patients receiving the drug. Infection and bleeding have occurred in about 12 and 5%, respectively, of pediatric patients receiving teniposide monotherapy.

From 4% to 12% of a dose is excreted in urine as parent drug. Fecal excretion of radioactivity within 72 hours after dosing accounted for 0% to 10% of the dose.


Clearance

10.3 mL/min/m2


Teniposide was detected in intracerebral tumors at concentrations of 0.05-1.12 ug/g tissue in 11 patients given 100-150 mg/sq m teniposide 1.5-3 hr before tumor resection. The concentrations in adjacent normal brain tissue were low (< 0.9 ug/g tissue) in three patients and undetectable (< 0.05 ug/g tissue) in the others

5.6 Metabolism/Metabolites

In isolated human liver preparations, cytochrome P450 mixed-function isozymes catalysed metabolism of the (pendant) E-ring to O-demethylated and catechol metabolites. This metabolism was subsequently attributed primarily to CYP3A4 activity and to a lesser degree to CYP3A5. Peroxidase-mediated O-demethylation of teniposide has also been reported.

IARC. Monographs on the Evaluation of the Carcinogenic Risk of Chemicals to Humans. Geneva: World Health Organization, International Agency for Research on Cancer, 1972-PRESENT. (Multivolume work). Available at: https://monographs.iarc.fr/ENG/Classification/index.php, p. V76 269 (2000)


In children given teniposide, the main metabolite in serum and urine was reported to be the hydroxy acid, formed by opening of the lactone ring; the cis-isomer, which may be a degradation product formed during storage, was also detected. The aglycone, formed by loss of the glucopyranoside moiety, was not detected (Evans et al., 1982). The hydroxy acid has not been found in plasma or urine in other studies with high doses of teniposide, and no changes in the measured concentration of teniposide in these samples was found after incubation with glucuronidase, indicating formation of little or none of the proposed glucuronide metabolites (Holthuis et al., 1987). In another study, however, 6% of the administered dose of teniposide was excreted in the urine as parent drug over 24 h, and a further 8% as a proposed aglycone glucuronide, which was not formally identified.

In general, the effects of teniposide in mammalian cells in vitro occurred in the absence of exogenous metabolic activation. Various metabolic species of teniposide have been identified, but their mutagenic properties have not been studied.

5.8 Mechanism of Action

The mechanism of action appears to be related to the inhibition of type II topoisomerase activity since teniposide does not intercalate into DNA or bind strongly to DNA. Teniposide binds to and inhibits DNA topoisomerase II. The cytotoxic effects of teniposide are related to the relative number of double-stranded DNA breaks produced in cells, which are a reflection of the stabilization of a topoisomerase II-DNA intermediate.


It is an inhibitor of DNA topoisomerase II enzymes: Teniposide is a DNA topoisomerase II poison that has been shown to promote DNA cleavage, with a strong preference for a C or T at position -1. Most of the mutational events reported in mammalian cells, including point mutations, chromosomal deletions and exchanges and aneuploidy, can be explained by this activity. Teniposide does not inhibit bacterial topoisomerases and may not mutate bacterial cells by the same mechanism as mammalian cells. Unlike many other DNA topoisomerase II poisons, teniposide does not bind to DNA, either covalently or by intercalation. Instead, it appears to interact directly with the DNA topoisomerase II enzyme.

IARC. Monographs on the Evaluation of the Carcinogenic Risk of Chemicals to Humans. Geneva: World Health Organization, International Agency for Research on Cancer, 1972-PRESENT. (Multivolume work). Available at: https://monographs.iarc.fr/ENG/Classification/index.php, p. V76 277 (2000)


... The drug appears to produce its cytotoxic effects by damaging DNA and thereby inhibiting or altering DNA synthesis. Teniposide has been shown to induce single-stranded DNA breaks; the drug also induces double-stranded DNA breaks and DNA-protein cross links. ... Teniposide appears to be cell cycle specific, inducing G2-phase arrest and preferentially killing cells in the G2 and late S phases.
