Thiotepa for injection is contraindicated in: Patients with severe hypersensitivity to thiotepa [see Warnings and Precautions (5.2)] Concomitant use with live or attenuated vaccines [see Warnings and Precautions (5.4)]
Warnings
BOXED WARNING SECTION
WARNING: SEVERE MYELOSUPPRESSION, CARCINOGENICITY • Thiotepa may cause severe marrow suppression, and high doses may cause marrow ablation with resulting infection or bleeding. Monitor hematologic laboratory parameters. Hematopoietic progenitor (stem) cell transplantation (HSCT) is required to prevent potentially fatal complications of the prolonged myelosuppression after high doses of thiotepa [see Warnings and Precautions (5.1) ] • Thiotepa should be considered potentially carcinogenic in humans [see Warnings and Precautions (5.7)]

10 OVERDOSE
There is no experience with overdoses of thiotepa. The most important adverse reactions expected in case of overdose are myeloablation and pancytopenia [see Nonclinical Toxicology (13.2)] . There is no known antidote for thiotepa. Monitor the hematological status closely and provide vigorous supportive measures as medically indicated.

11 DESCRIPTION
DESCRIPTION SECTION
Thiotepa is an alkylating agent. Thiotepa for injection, USP is supplied as a non-pyrogenic, sterile lyophilized white powder for intravenous, intracavitary, or intravesical use after reconstitution and dilution. Thiotepa for injection, USP is available in a single-dose vial containing: 15 mg thiotepa. After reconstitution with 1.5 ml of water for injection, each ml contains 10 mg thiotepa. 100 mg thiotepa. After reconstitution with 10 ml of water for injection, each ml contains 10 mg 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 C 6 H 12 N 3 PS, and a molecular weight of 189.22, and it appears as fine, white crystalline flakes, with a melting range of 52°C to 57°C. It is soluble in alcohol, in chloroform and in ether; soluble in water and methanol. When reconstituted with sterile water for injection, the resulting solution has a pH of approximately 5.5 to 7.5. Thiotepa is unstable in acid medium.

14 CLINICAL STUDIES
CLINICAL STUDIES SECTION
Thiotepa was evaluated in a retrospective study of pediatric patients with class 3 beta-thalassemia who underwent allogeneic hematopoietic progenitor (stem) cell transplantation (HSCT) from a human leukocyte antigen (HLA)-identical sibling donor. Twenty-five patients (10 male and 15 female) of median age 10 years (range, 5-16 years) were treated with intravenous busulfan at weight-based dosing from Day -10 to Day -7 pretransplant [see Table 1] ), intravenous thiotepa 5 mg/kg twice on Day -6, intravenous cyclophosphamide 40 mg/kg/day on Day -5 to Day -2, and marrow infusion on Day 0. All patients had also received precytoreduction with hydroxyurea, azathioprine and fludarabine prior to start of the preparative regimen. Efficacy was based on the incidence of graft rejection (primary or late rejection). The incidence of graft rejection in these 25 patients using thiotepa was 0% (95% CI: [0, 0.12]). Of the 51 patients who received the same preparative regimen, historically, without thiotepa, the incidence of graft rejection reported was 25.5% (95% CI: [0.13, 0.37]).
