Overview

Teniposide is an antineoplastic and a mitotic inhibitor that is FDA approved for the treatment of childhood acute lymphoblastic leukemia. Common adverse reactions include diarrhea, inflammatory disease of mucous membrane, nausea, vomiting, anemia, leukopenia, thrombocytopenia and infectious disease.

Contraindications

  • Teniposide is generally contraindicated in patients who have demonstrated a previous hypersensitivity to teniposide and/or polyoxyl 35 castor oil.

Warnings

  • Teniposide is a potent drug and should be used only by physicians experienced in the administration of cancer chemotherapeutic drugs. Blood counts, as well as renal and hepatic function tests, should be carefully monitored prior to and during therapy.
  • Patients being treated with teniposide injection should be observed frequently for myelosuppression both during and after therapy. Dose-limiting bone marrow suppression is the most significant toxicity associated with teniposide therapy. Therefore, the following studies should be obtained at the start of therapy and prior to each subsequent dose of teniposide: hemoglobin, white blood cell count and differential, and platelet count. If necessary, repeat bone marrow examination should be performed prior to the decision to continue therapy in the setting of severe myelosuppression.

Physicians should be aware of the possible occurrence of a hypersensitivity reaction variably manifested by chills, fever, urticaria, tachycardia, bronchospasm, dyspnea, hypertension, orhypotension, rash, and facial flushing. This reaction may occur with the first dose of teniposide and may be life threatening if not treated promptly with antihistamines, corticosteroids, epinephrine, intravenous fluids, and other supportive measures as clinically indicated. The exact cause of these reactions is unknown. They may be due to the polyoxyl 35 castor oil componentof the vehicle or to teniposide itself. Patients who have experienced prior hypersensitivity reactions to teniposide are at risk for recurrence of symptoms and should only be retreatedreactions has been accomplished using measures described above. To date, there is no evidence to suggest cross-sensitization between teniposide and etoposide.

One episode of sudden death, attributed to probable arrhythmia and intractable hypotension, has been reported in an elderly patient receiving teniposide combination therapy for a nonleukemicmalignancy.

  • Patients receiving teniposide treatment should be under continuous observation for at least the first 60 minutes following the start ofthe infusion and at frequent intervals thereafter. If symptoms or signs of anaphylaxis occur, the infusion should be stopped immediately, followed by the administration of epinephrine, corticosteroids, antihistamines, pressor agents, or volume expanders at the discretion of the physician. An aqueous solution of epinephrine 1:1000 and a source of oxygen should beavailable at the bedside.
  • For parenteral administration, teniposide should be given only by slow intravenous infusion (lasting at least 30 to 60 minutes) since hypotension has been reported as a possible side effect of rapid intravenous injection, perhaps due to a direct effect of polyoxyl 35 castor oil. If clinically significant hypotension develops, the teniposide infusion should be discontinued. The blood pressure usually normalizes within hours in response to cessation of the infusion and administration of fluids or other supportive therapy as appropriate. If the infusion is restarted, a slower administration rate should be used and the patient should be carefully monitored.
  • Acute central nervous system depression, hypotension, and metabolic acidosis have been observed in patients receiving investigational infusions of high-dose teniposide who were pretreated with antiemetic drugs. The depressant effects of the antiemetic agents and the alcohol content of the teniposide formulation may place patients receiving higher than recommended doses of teniposide a risk for central nervous system depression.

Adverse Reactions

Clinical Trials Experience

The table below presents the incidences of adverse reactions derived from an analysis of data contained within literature reports of 7 studies involving 303 pediatric patients in which teniposide was administered by injection as a single agent in a variety of doses and schedules for a variety of hematologic malignancies and solid tumors. The total number of patients evaluable for a given event was not 303 since the individual studies did not address the occurrence of each event listed. Five of these 7 studies assessed teniposide activity in hematologic malignancies, such as leukemia. Thus, many of these patients had abnormal hematologic status at start of therapy with teniposide and were expected to develop significant myelosuppression as an endpoint of treatment.

Hematologic Toxicity

Gastrointestinal Toxicity

  • Nausea and vomiting are the most common gastrointestinal toxicities, having occurred in 29% of evaluable pediatric patients. The severity of this nausea and vomiting is generally mild to moderate.

Hypotension

  • Transient hypotension following rapid intravenous administration has been reported in 2% of evaluable pediatric patients. One episode of sudden death, attributed to probable arrhythmia and intractable hypotension, has been reported in an elderly patient receiving teniposide combination therapy for a non-leukemic malignancy.
  • No other cardiac toxicity or electrocardiographic changes have been documented. No delayed hypotension has been noted.

Allergic Reactions

Central Nervous System

Alopecia

  • Alopecia, sometimes progressing to total baldness, was observed in 9% of evaluable pediatric patients who received teniposide as single-agent therapy. It was usually reversible.
