Thiotepa for Injection, USP is an ethylenimine-type compound. It is supplied as a non-pyrogenic, sterile Iyophilized powder for intravenous, intracavitary or intravesical administration, containing 15 mg of thiotepa. Thiotepa is a synthetic product with antitumor activity. The chemical name for thiotepa is Tris(1-aziridinyl)phosphine sulfide. Thiotepa has the following structural formula:
Thiotepa has the molecular formula C6H12N3PS, and a molecular weight of 189.22. When reconstituted with sterile water for injection, the resulting solution has a pH of approximately 5.5 to 7.5. Thiotepa is stable in alkaline medium and unstable in acid medium./ ~6 w" q& G  f( E! Z; e
CLINICAL PHARMACOLOGY * @2 Z# p' d3 _( {( A; X
Thiotepa is a cytotoxic agent of the polyfunctional type, related chemically and pharmacologically to nitrogen mustard. The radiomimetic action of thiotepa is believed to occur through the release of ethylenimine radicals which, like irradiation, disrupt the bonds of DNA. One of the principal bond disruptions is initiated by alkylation of guanine at the N-7 position, which severs the linkage between the purine base and the sugar and liberates alkylated guanines.& J- x$ e- _  N6 R% C6 @- S- Y$ ^
The pharmacokinetics of thiotepa and TEPA in thirteen female patients (45 to 84 years) with advanced stage ovarian cancer receiving 60 mg and 80 mg thiotepa by intravenous infusion on subsequent courses given at 4-week intervals are presented in the following table:

TEPA, which possesses cytotoxic activity, appears to be the major metabolite of thiotepa found in human serum and urine. Urinary excretion of 14C-labeled thiotepa and metabolites in a 34 year old patient with metastatic carcinoma of the cecum who received a dose of 0.3 mg/kg intravenously was 63%. Thiotepa and TEPA in urine each accounts for less than 2% of the administered dose.$ e6 X) U+ t! }, v7 n2 i+ P

CONTRAINDICATIONS
4 i1 h0 \0 j* x$ h4 A- q5 r
Thiotepa is contraindicated in patients with a known hypersensitivity (allergy) to this preparation.* I1 U( j0 f2 u/ |7 t
Therapy is probably contraindicated in cases of existing hepatic, renal, or bone-marrow damage. However, if the need outweighs the risk in such patients, thiotepa may be used in low dosage, and accompanied by hepatic, renal and hemopoietic function tests. 4 A8 d1 [% h, U3 ~
WARNINGS ( h8 j, c' E! v1 u  q
Death has occurred after intravesical administration, caused by bone-marrow depression from systematically absorbed drug.$ a/ u1 S& a! Z
Death from septicemia and hemorrhage has occurred as a direct result of hematopoietic depression by thiotepa.! ?+ Y( O, S7 f, J9 a8 v5 N
Thiotepa is highly toxic to the hematopoietic system. A rapidly falling white blood cell or platelet count indicates the necessity for discontinuing or reducing the dosage of thiotepa. Weekly blood and platelet counts are recommended during therapy and for at least 3 weeks after therapy has been discontinued.
2 a" _( i- g5 V  V7 YThiotepa can cause fetal harm when administered to a pregnant woman. Thiotepa given by the intraperitoneal (IP) route was teratogenic in mice at doses ≥ 1 mg/kg (3.2 mg/m2), approximately 8-fold less than the maximum recommended human therapeutic dose (0.8 mg/kg, 27 mg/m2), based on body-surface area. Thiotepa given by the IP route was teratogenic in rats at doses ≥ 3 mg/kg (21 mg/m2), approximately equal to the maximum recommended human therapeutic dose, based on body-surface area. Thiotepa was lethal to rabbit fetuses at a dose of 3 mg/kg (41 mg/m2), approximately two times the maximum recommended human therapeutic dose based on body-surface area.
, x3 x# H3 q" g6 E/ B' U/ OEffective contraception should be used during thiotepa therapy if either the patient or partner is of childbearing potential. There are no adequate and well-controlled studies in pregnant women. If thiotepa is used during pregnancy, or if pregnancy occurs during thiotepa therapy, the patient and partner should be apprised of the potential hazard to the fetus.
2 ^  @+ |- X, B1 |8 Q- R3 }Thiotepa is a polyfunctional alkylating agent, capable of cross-linking the DNA within a cell and changing its nature. The replication of the cell is, therefore, altered, and thiotepa may be described as mutagenic. An in vitro study has shown that it causes chromosomal aberrations of the chromatid type and that the frequency of induced aberrations increases with the age of the subject.. |9 T3 k! ]* g4 i
Like many alkylating agents, thiotepa has been reported to be carcinogenic when administered to laboratory animals. Carcinogenicity is shown most clearly in studies using mice, but there is some evidence of carcinogenicity in man. In patients treated with thiotepa, cases of myelodysplastic syndromes and acute non-lymphocytic leukemia have been reported.

GeneralThe serious complication of excessive thiotepa therapy, or sensitivity to the effects of thiotepa, is bone-marrow depression. If proper precautions are not observed thiotepa may cause leukopenia, thrombocytopenia, and anemia.
( T# G: G! J$ c% ?3 WInformation for PatientsThe patient should notify the physician in the case of any sign of bleeding (epistaxis, easy bruising, change in color of urine, black stool) or infection (fever, chills) or for possible pregnancy to patient or partner.- j( x. Z+ [- X8 P  H7 y
Effective contraception should be used during thiotepa therapy if either the patient or the partner is of childbearing potential.; ^+ \7 `" A& U
Laboratory TestsThe most reliable guide to thiotepa toxicity is the white blood cell count. If this falls to 3000 or less, the dose should be discontinued. Another good index of thiotepa toxicity is the platelet count; if this falls to 150,000, therapy should be discontinued. Red blood cell count is a less accurate indicator of thiotepa toxicity. If the drug is used in patients with hepatic or renal damage (see CONTRAINDICATIONS section), regular assessment of hepatic and renal function tests are indicated.
- \! Y, c2 ~4 Z) G& v) s# u% u/ HDrug InteractionsIt is not advisable to combine, simultaneously or sequentially, cancer chemotherapeutic agents or a cancer chemotherapeutic agent and a therapeutic modality having the same mechanism of action. Therefore, thiotepa combined with other alkylating agents such as nitrogen mustard or cyclophosphamide or thiotepa combined with irradiation would serve to intensify toxicity rather than to enhance therapeutic response. If these agents must follow each other, it is important that recovery from the first agent, as indicated by white blood cell count, be complete before therapy with the second agent is instituted.

Carcinogenesis- J4 O6 Y* ?# T+ u
In mice, repeated IP administration of thiotepa (1.15 or 2.3 mg/kg three times per week for 52 or 43 weeks, respectively) produced a significant increase in the combined incidence of squamous-cell carcinomas of the skin, preputial gland, and ear canal, and combined incidence of lymphoma and lymphocytic leukemia. In other studies in mice, repeated IP administration of thiotepa (4 or 8 mg/kg three times per week for 4 weeks followed by a 20 week observation period or 1.8 mg/kg three times per week for 4 weeks followed by a 35 week observation period) resulted in an increased incidence of lung tumors. In rats, repeated IP administration of thiotepa (0.7 or 1.4 mg/kg three times per week for 52 or 34 weeks, respectively) produced significant increases in the incidence of squamous-cell carcinomas of the skin or ear canal, combined hematopoietic neoplasms, and uterine adenocarcinomas. Thiotepa given intravenously (IV) to rats (1 mg/kg once per week for 52 weeks) produced an increased incidence of malignant tumors (abdominal cavity sarcoma, lymphosarcoma myelosis, seminoma, fibrosarcoma, salivary gland hemangioendothelioma, mammary sarcoma, pheochromocytoma) and benign tumors.
  E! {  _6 H% j: `The lowest reported carcinogenic dose in mice (1.15 mg/kg, 3.68 mg/m2) is approximately 7-fold less than the maximum recommended human therapeutic dose based on body-surface area.

Mutagenesis
5 P3 I3 J" `( J2 B7 ], W! U  fThiotepa was mutagenic in in vitro assays in Salmonella typhimurium, E coli, Chinese hamster lung and human lymphocytes. Chromosomal aberrations and sister chromatid exchanges were observed in vitro with thiotepa in bean root tips, human lymphocytes, Chinese hamster lung, and monkey lymphocytes. Mutations were observed with oral thiotepa in mouse at doses > 2.5 mg/kg (8 mg/m2). The mouse micronucleus test was positive with IP administration of > 1 mg/kg (3.2 mg/m2). Other positive in vivo chromosomal aberration or mutation assays included Drosophila melanogaster, Chinese hamster marrow, murine marrow, monkey lymphocyte, and murine germ cell.

Thiotepa impaired fertility in male mice at PO or IP doses ≥ 0.7 mg/kg (2.24 mg/m2), approximately 12-fold less than the maximum recommended human therapeutic dose based on body-surface area. Thiotepa (0.5 mg) inhibited implantation in female rats when instilled into the uterine cavity. Thiotepa interfered with spermatogenesis in mice at IP doses ≥ 0.5 mg/kg (1.6 mg/m2), approximately 17-fold less than the maximum recommended human therapeutic dose based on body-surface area. Thiotepa interfered with spermatogenesis in hamsters at an IP dose of 1 mg/kg (4.1 mg/m2), approximately 7-fold less than the maximum recommended human therapeutic dose based on body-surface area.
