( 4 ) Concomitant use with live or attenuated vaccines. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Cutaneous toxicity: Cleanse skin at least twice daily through 48 hours after the last dose of thiotepa for injection. ( 5.3) Embryo-Fetal toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to avoid pregnancy. ( 5.8 )
5.1Myelosuppression The consequence of treatment with high doses of thiotepa for injection together with other chemotherapy is profound myelosuppression occurring in all patients. Monitor complete blood counts, and provide supportive care for infections, anemia and thrombocytopenia until there is adequate hematopoietic recovery. For patients receiving thiotepa for injection for treatment of adenocarcinoma of the breast, adenocarcinoma of the ovary, malignant effusions and superficial papillary carcinoma of the urinary bladder, if the bone marrow has been compromised by prior irradiation or chemotherapy, or is recovering from chemotherapy, the risk of severe myelosuppression with thiotepa for injection may be increased.
Perform periodic complete blood counts during the course of treatment with thiotepa for injection. Provide supportive care for infections, bleeding, and symptomatic anemia [see Adverse Reactions (6.1 )] . Pediatric use information is approved for Adienne SA’s TEPADINA (thiotepa) for Injection.
However, due to Adienne SA’s marketing exclusivity rights, the drug product is not labeled with that information.
5.2Hypersensitivity Clinically significant hypersensitivity reactions, including anaphylaxis, have occurred following administration of thiotepa for injection. If anaphylactic or other clinically significant allergic reaction occurs, discontinue treatment with thiotepa for injection, initiate appropriate therapy, and monitor until signs and symptoms resolve [see Contraindications (4) , Adverse Reactions (6.1 )] .
5.3Cutaneous Toxicity Thiotepa for injection and/or its active metabolites may be excreted in part via skin patients receiving high-dose therapy. Treatment with thiotepa for injection may cause skin discoloration, pruritus, blistering, desquamation, and peeling that may be more severe in the groin, axillae, skin folds, in the neck area, and under dressings. Instruct patients to shower or bathe with water at least twice daily through 48 hours after administration of thiotepa for injection.
Change occlusive dressing and clean the covered skin at least twice daily through 48 hours after administration of thiotepa for injection. Change bed sheets daily during treatment. Skin reactions associated with accidental exposure to thiotepa for injection may also occur.
Wash the skin thoroughly with soap and water in case thiotepa solution contacts the skin. Flush mucous membranes in case of thiotepa for injection contact with mucous membranes.
5.4Concomitant Use of Live and Attenuated Vaccines Do not administer live or attenuated viral or bacterial vaccines to a patient treated with thiotepa for injection until the immunosuppressive effects have resolved.
5.5Hepatic Veno-Occlusive Disease Hepatic veno-occlusive disease may occur in patients who have received high-dose thiotepa for injection in conjunction with busulfan and cyclophosphamide. Monitor by physical examination, serum transaminases and bilirubin, and provide supportive care to patients who develop hepatic veno-occlusive disease. Pediatric use information is approved for Adienne SA’s TEPADINA (thiotepa) for Injection.
However, due to Adienne SA’s marketing exclusivity rights, the drug product is not labeled with that information.
5.6Central Nervous System Toxicity Fatal encephalopathy has occurred in patients treated with high doses of thiotepa.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Myelosuppression [ see Warnings and Precautions ( 5.1 )] Infection [ see Warnings and Precautions (5.1 ) ] Hypersensitivity [ see Warnings and Precautions (5.2) ] Cutaneous Toxicity [ see Warnings and Precautions (5.3 ) ] Hepatic Veno-Occlusive Disease [ see Warnings and Precautions (5.5 ) ] Central Nervous System Toxicity [ see Warnings and Precautions (5.6 )] Carcinogenicity [ see Warnings and Precautions (5.7 )] The most common adverse reactions (incidence greater than 10%) were neutropenia, anemia, thrombocytopenia, elevated alanine aminotransferase, elevated aspartate aminotransferase, elevated bilirubin, mucositis, cytomegalovirus infection, hemorrhage, diarrhea, hematuria and rash ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Hikma Pharmaceuticals USA Inc. at 877-845-0689 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse reactions with treatment of adenocarcinoma of the breast, adenocarcinoma of the ovary, malignant effusions and superficial papillary carcinoma of the urinary bladder Gastrointestinal : Nausea, vomiting, abdominal pain, anorexia.
General : Fatigue, weakness. Febrile reaction and discharge from a subcutaneous lesion may occur as the result of breakdown of tumor tissue. Hypersensitivity Reactions : Allergic reactions - rash, urticaria, laryngeal edema, asthma, anaphylactic shock, wheezing.
Local Reactions : Contact dermatitis, pain at the injection site. Neurologic : Dizziness, headache, blurred vision. Renal : Dysuria, urinary retention, chemical cystitis or hemorrhagic cystitis.
Reproductive : Amenorrhea, interference with spermatogenesis. Respiratory : Prolonged apnea has been reported when succinylcholine was administered prior to surgery, following combined use of thiotepa and other anticancer agents. It was theorized that this was caused by decrease of pseudocholinesterase activity caused by the anticancer drugs.
Skin : Dermatitis, alopecia. Skin depigmentation has been reported following topical use. Special Senses : Conjunctivitis.
Pediatric use information is approved for Adienne SA’s TEPADINA (thiotepa) for Injection. However, due to Adienne SA’s marketing exclusivity rights, the drug product is not labeled with that information.
6.2Postmarketing Experience Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

7 DRUG INTERACTIONS
7.1Effect of Cytochrome CYP3A Inhibitors and Inducers In vitro studies suggest that thiotepa is metabolized by CYP3A4 and CYP2B6 to its active metabolite TEPA. Avoid coadministration of strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin, ritonavir) and strong CYP3A4 inducers (e.g., rifampin, phenytoin) with thiotepa due to the potential effects on efficacy and toxicity [see Clinical Pharmacology (12.2) ] . Consider alternative medications with no or minimal potential to inhibit or induce CYP3A4.
If concomitant use of strong CYP3A4 modulators cannot be avoided, closely monitor for adverse drug reactions.
7.2Effect of Thiotepa for Injection on Cytochrome CYP2B6 Substrates In vitro studies suggest that thiotepa inhibits CYP2B6. Thiotepa for injection may increase the exposure of drugs that are substrates of CYP2B6 in patients; however, the clinical relevance of this in vitro interaction is unknown [see Clinical Pharmacology (12.2 )] . The administration of thiotepa with cyclophosphamide in patients reduces the conversion of cyclophosphamide to the active metabolite, 4-hydroxycyclophosphamide; the effect appears sequence dependent with a greater reduction in the conversion to 4-hydroxycyclophosphamide when thiotepa is administered 1.5 hours prior to the intravenous administration of cyclophosphamide compared to administration of thiotepa after intravenous cyclophosphamide [see Clinical Pharmacology (12.2 )] .
The reduction in 4-hydroxycyclophosphamide levels may potentially reduce efficacy of cyclophosphamide treatment.
7.1Effect of Cytochrome CYP3A Inhibitors and Inducers In vitro studies suggest that thiotepa is metabolized by CYP3A4 and CYP2B6 to its active metabolite TEPA. Avoid coadministration of strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin, ritonavir) and strong CYP3A4 inducers (e.g., rifampin, phenytoin) with thiotepa due to the potential effects on efficacy and toxicity [see Clinical Pharmacology (12.2) ] .

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Breastfeeding is not recommended. ( 8.2 ) Moderate or severe renal impairment: Monitor patients more frequently for toxicity. ( 8.6 , 12.2 ) Moderate or severe hepatic impairment: Monitor patients more frequently for toxicity.
( 8.7, 12.2 ) See 17 for Patient Counseling Information Pediatric use information is approved for Adienne SA’s TEPADINA (thiotepa) for Injection. However, due to Adienne SA’s marketing exclusivity rights, the drug product is not labeled with that information.
8.1Pregnancy Thiotepa for injection can cause fetal harm when administered to a pregnant woman based on findings from animals and the drug’s mechanism of action [ see Clinical Pharmacology (12.1 ) ]. Limited available data with thiotepa for injection use in pregnant women are insufficient to inform a drug-associated risk of major birth defects and miscarriage. In animal reproduction studies, administration of thiotepa to pregnant mice and rats during organogenesis produced teratogenic effects (neural tube defects and malformations of the skeletal system of the fetus) at doses approximately 0.125 and 1 times, respectively, the maximum recommended human daily dose on a mg/m 2 basis.
Thiotepa was lethal to rabbit fetuses at approximately 2 times the maximum recommended human therapeutic dose based on body-surface area [see Data]. Consider the benefits and risks of thiotepa for injection for the mother and possible risks to the fetus when prescribing thiotepa for injection to a pregnant woman. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Thiotepa given by the IP route in mice at doses ≥ 1 mg/kg (3.2 mg/m 2 ), approximately 8-fold less than the maximum recommended human therapeutic dose based on body-surface area, and in rats at doses ≥ 3 mg/kg (21 mg/m 2 ), approximately equal to the maximum recommended human therapeutic dose based on body-surface area, resulted in various malformations including neural tube defects, omphalocele, renal agenesis, atresia ani, limb and digit defects, cleft palate, micrognathia, other skeletal anomalies in the skull, vertebrae and ribs, and reduced skeletal ossification.
Thiotepa was lethal to rabbit fetuses at a dose of 3 mg/kg (41 mg/m 2 ), approximately 2 times the maximum recommended human therapeutic dose based on body-surface area.
8.2Lactation Risk Summary There is no information regarding the presence of thiotepa in human milk, the effects on the breastfed infant, or the effects on milk production. Because of the potential for serious adverse reactions, including the potential for tumorigenicity shown for thiotepa in animal studies, advise patients not to breastfeed during thiotepa for injection treatment.
8.3Females and Males of Reproductive Potential Pregnancy testing Thiotepa for injection can cause fetal harm when administered to a pregnant female. Verify the pregnancy status of females of reproductive potential prior to initiating thiotepa for injection therapy. Contraception Females Advise females of reproductive potential to avoid pregnancy during thiotepa for injection treatment and for at least 6 months after the final dose of thiotepa for injection.
Advise females to immediately report pregnancy [see Use in Specific Populations (8.1 )]. Males Thiotepa for injection may damage spermatozoa and testicular tissue, resulting in possible genetic abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during thiotepa for injection treatment and for at least 1 year after the final dose of thiotepa for injection [ see Nonclinical Toxicology (13.1) ].

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of thiotepa for injection in neonates have not been established. Safety and effectiveness of thiotepa for injection for treatment of adenocarcinoma of the breast, adenocarcinoma of the ovary, malignant effusions and superficial papillary carcinoma of the urinary bladder in pediatric patients have not been established. Pediatric use information is approved for Adienne SA’s TEPADINA (thiotepa) for Injection.
However, due to Adienne SA’s marketing exclusivity rights, the drug product is not labeled with that information.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of thiotepa for injection for treatment of adenocarcinoma of the breast, adenocarcinoma of the ovary, malignant effusions and superficial papillary carcinoma of the urinary bladder did not include sufficient numbers of subjects aged 65 and over to determine whether elderly subjects respond differently from younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreasing hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE There is no experience with overdoses of thiotepa [see Nonclinical Toxicology (13.1) ] . The most important adverse reactions expected in case of overdose are myeloablation and pancytopenia. There is no known antidote for thiotepa. Monitor the hematological status closely and provide vigorous supportive measures as medically indicated.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Thiotepa is a cytotoxic agent of the polyfunctional type, related chemically and pharmacologically to the nitrogen mustard. The radiomimetic action of thiotepa is believed to occur through the release of ethyleneimine radicals which, like irradiation, disrupt the bonds of DNA. One of the principle 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.
12.2Pharmacodynamics Absorption Thiotepa reached maximal concentrations close to the end infusion following an intravenous infusion. Distribution The binding of thiotepa to plasma proteins is approximately 10% to 20%. In adults administered intravenous thiotepa between 20 mg to 250 mg/m 2 as an intravenous bolus or infusion up to 4 hours, the mean volume of distribution of thiotepa ranged from 1 L/kg (30%) to
1.9L/kg (17%). Elimination In adults administered intravenous thiotepa between 20 mg to 250 mg/m 2 as an intravenous bolus or infusion up to 4 hours, the mean thiotepa clearance ranged from
14.6 L/hr/m 2 (23%) to
27.9L/hr/m 2 (69%). In adult population, the mean terminal elimination half-life ranged from 1.4 hours (7%) to 3.7 hours (14%) for thiotepa and from 4.9 hours to 17.6 hours (20%) for TEPA. Metabolism Thiotepa undergoes hepatic metabolism.
In vitro data suggests that CYP3A4 and CYP2B6 may be responsible for the metabolism of thiotepa to TEPA, a major active metabolite. Excretion In adult patients, urinary excretion of thiotepa accounted for less than 2% of the dose and TEPA accounted for 11% or less of the dose. Specific Populations Hepatic Impairment The exposure (as measured by area under the curve (AUC)) of thiotepa increased by 1.6-fold and 1.8-fold following administration of multiple thiotepa doses of 7 mg/kg administered every 2 days with cyclophosphamide in two adult patients who had liver metastases with moderate hepatic impairment compared to the exposure observed in one patient with normal hepatic function .
The effect of severe hepatic impairment on thiotepa exposure is unknown. Renal Impairment The exposure (as measured by AUC) of thiotepa increased by 1.4-fold and TEPA increased by 2.6-fold following administration of multiple doses of 120 mg/m 2 /day in one patient with moderate renal impairment (CLcr = 38 mL/min) administered cyclophosphamide plus thiotepa plus carboplatin, compared to exposure of thiotepa in patients with normal renal function. The effects of severe renal impairment or end-stage renal disease on thiotepa exposure are unknown.
Drug Interactions The clinical relevance of in vitro inhibition of the cytochrome P450 enzymes described below is unknown, but it cannot be excluded that the systemic exposure of thiotepa or medicinal products that are substrates for these enzymes may be affected with concomitant administration with thiotepa for injection. Effect of Cytochrome P450 Modulators on Thiotepa In vitro data demonstrates that CYP3A4 and CYP2B6 inhibitors decrease the metabolism of thiotepa [see Drug Interactions (7.1) ] . Effect of Thiotepa on Cytochrome P450 2B6 In vitro data demonstrates that thiotepa inhibits CYP2B6.
Effect of Thiotepa on Cyclophosphamide The administration of thiotepa 1.5 hours prior to intravenous cyclophosphamide in patients administered cyclophosphamide plus thiotepa plus carboplatin decreased the AUC of 4-hydroxycyclophosphamide by 26% and maximal concentrations of 4-hydroxycyclophosphamide by 62%, compared to administration of cyclophosphamide prior to thiotepa.

🧬 Mechanism of Action ▾
12.1Mechanism of Action Thiotepa is a cytotoxic agent of the polyfunctional type, related chemically and pharmacologically to the nitrogen mustard. The radiomimetic action of thiotepa is believed to occur through the release of ethyleneimine radicals which, like irradiation, disrupt the bonds of DNA. One of the principle 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.
