Patients with hepatic disorders  
Thiotepa has not been studied in patients with hepatic impairment. Since thiotepa is mainly  
metabolized through the liver, caution needs to be exercised when thiotepa is used in patients with  
pre-existing impairment of liver function, especially in those with severe hepatic impairment. Dose  
modification is not recommended for transient alterations of hepatic parameters (see section  
Warnings and precautions).  
Patients with renal disorders  
Studies in renally impaired patients have not been conducted. As thiotepa and its metabolites are  
poorly excreted in the urine, dose modification is not recommended in patients with mild or moderate  
4 / 22  
Product information for human medicinal products  
renal insufficiency. However, caution is recommended (see section Warnings and precautions and  
Pharmacokinetics).  
Elderly patients  
The administration of thiotepa has not been specifically investigated in elderly patients. However, in  
clinical studies, a proportion of patients over the age of 65 received the same cumulative dose as the  
other patients. No dose adjustment was deemed necessary.

Mode of administration  
TEPADINA® must be administered by a qualified healthcare professional as a 2-4 hours intravenous  
infusion via a central venous catheter.  
Each TEPADINA® 15mg vial must be reconstituted with 1,5 ml of sterile water for injection and each  
TEPADINA® 100mg vial must be reconstituted with 10 ml of sterile water for injection. The total  
volume of reconstituted vials to be administered should be further diluted in 500 ml of sodium chloride  
9 mg/ml (0.9%) solution for injection prior to administration (1000 ml if the dose is higher than 500  
mg). In children, if the dose is lower than 250 mg, an appropriate volume of sodium chloride 9 mg/ml  
(0.9%) solution for injection may be used in order to obtain a final TEPADINA® concentration between  
0.5 and 1 mg/ml. For instructions on reconstitution and further dilution prior to administration, see  
section Other information - Instructions for handling.  
Precautions to be taken before handling or administering the product  
Topical reactions associated with accidental exposure to thiotepa may occur. Therefore, the use of  
gloves is recommended in preparing the solution for infusion. If thiotepa solution accidentally contacts  
6 / 22  
Product information for human medicinal products  
the skin, the skin must be immediately thoroughly washed with soap and water. If thiotepa  
accidentally contacts mucous membranes, they must be flushed thoroughly with water (see section  
Other information - Instructions for handling).  
Contraindications  
Hypersensitivity to the active substance.  
Pregnancy and lactation (see section Pregnancy, lactation).  
Concomitant use with yellow fever vaccine and with live virus and bacterial vaccines (see section  
Interactions).  
Warnings and precautions  
The consequence of treatment with thiotepa at the recommended dose and schedule is profound  
myelosuppression, occurring in all patients. Severe granulocytopenia, thrombocytopenia, anaemia or  
any combination thereof may develop. Frequent complete blood counts, including differential white  
blood cell counts, and platelet counts need to be performed during the treatment and until recovery is  
achieved. Platelet and red blood cell support, as well as the use of growth factors such as  
Granulocyte-colony stimulating factor (G-CSF), should be employed as medically indicated. Daily  
white blood cell counts and platelet counts are recommended during therapy with thiotepa and after  
transplant for at least 30 days.  
Prophylactic or empiric use of anti-infectives (bacterial, fungal, viral) should be considered for the  
prevention and management of infections during the neutropenic period.  
Thiotepa has not been studied in patients with hepatic impairment. Since thiotepa is mainly  
metabolized through the liver, caution needs to be observed when thiotepa is used in patients with  
pre-existing impairment of liver function, especially in those with severe hepatic impairment. When  
treating such patients it is recommended that serum transaminase, alkaline phosphatase and bilirubin  
are monitored regularly following transplant, for early detection of hepatotoxicity.  
Patients who have received prior radiation therapy, greater than or equal to three cycles of  
chemotherapy, or prior progenitor cell transplant may be at an increased risk of hepatic veno-  
occlusive disease (see section Undesirable effects).  
Caution must be used in patients with history of cardiac diseases, and cardiac function must be  
monitored regularly in patients receiving thiotepa.  
Caution must be used in patients with history of renal diseases and periodic monitoring of renal  
function should be considered during therapy with thiotepa.  
Thiotepa might induce pulmonary toxicity that may be additive to the effects produced by other  
cytotoxic agents (busulfan, fludarabine and cyclophosphamide) (see section Undesirable effects).  
7 / 22  
Product information for human medicinal products  
Previous brain irradiation or craniospinal irradiation may contribute to severe toxic reactions (e.g.  
encephalopathy).  
The increased risk of a secondary malignancy with thiotepa, a known carcinogen in humans, must be  
explained to the patient.  
Concomitant use with live attenuated vaccines (except yellow fever vaccines), phenytoin and  
fosphenytoin is not recommended (see section Interactions).  
Thiotepa must not be concurrently administered with cyclophosphamide when both medicinal  
products are present in the same conditioning treatment. TEPADINA® must be delivered after the  
completion of any cyclophosphamide infusion (see section Interactions).  
During the concomitant use of thiotepa and inhibitors of CYP2B6 or CYP3A4, patients should be  
carefully monitored clinically (see section Interactions).  
As most alkylating agents, thiotepa might impair male or female fertility. Male patients should seek for  
sperm cryopreservation before therapy is started and should not father a child while treated and  
during the year after cessation of treatment (see section Pregnancy, lactation).  
Interactions  
Specific interactions with thiotepa  
Live virus and bacterial vaccines must not be administered to a patient receiving an  
immunosuppressive chemotherapeutic agent and at least three months must elapse between  
discontinuation of therapy and vaccination.  
Thiotepa appears to be metabolised via CYP2B6 and CYP3A4. Co-administration with inhibitors of  
CYP2B6 (for example clopidogrel and ticlopidine) or CYP3A4 (for example azole antifungals,  
macrolides like erythromycin, clarithromycin, telithromycin, and protease inhibitors) may increase the  
plasma concentrations of thiotepa and potentially decrease the concentrations of the active metabolite  
TEPA. Co-administration of inducers of cytochrome P450 (such as rifampicin, carbamazepine,  
phenobarbital) may increase the metabolism of thiotepa leading to increased plasma concentrations  
of the active metabolite. Therefore, during the concomitant use of thiotepa and these medicinal  
products, patients should be carefully monitored clinically.  
Thiotepa is a weak inhibitor for CYP2B6, and may thereby potentially increase plasma concentrations  
of substances metabolised via CYP2B6, such as ifosfamide, tamoxifen, bupropion, efavirenz and  
cyclophosphamide. CYP2B6 catalyzes the metabolic conversion of cyclophosphamide to its active  
form 4-hydroxycyclophosphamide (4-OHCP) and co-administration of thiotepa may therefore lead to  
decreased concentrations of the active 4-OHCP. Therefore, a clinical monitoring should be exercised  
during the concomitant use of thiotepa and these medicinal products.

Contraindications of concomitant use  
Yellow fever vaccine: risk of fatal generalized vaccine-induced disease.  
More generally, live virus and bacterial vaccines must not be administered to a patient receiving an  
immunosuppressive chemotherapeutic agent and at least three months must elapse between  
discontinuation of therapy and vaccination.  
Concomitant use not recommended  
Live attenuated vaccines (except yellow fever): risk of systemic, possibly fatal disease. This risk is  
increased in subjects who are already immunosuppressed by their underlying disease.  
An inactivated virus vaccine should be used instead, whenever possible (poliomyelitis).  
Phenytoin: risk of exacerbation of convulsions resulting from the decrease of phenytoin digestive  
absorption by cytotoxic medicinal product or risk of toxicity enhancement and loss of efficacy of the  
cytotoxic medicinal product due to increased hepatic metabolism by phenytoin.  
Concomitant use to take into consideration  
Ciclosporine, tacrolimus: excessive immunosuppression with risk of lymphoproliferation.  
Alkylating chemotherapeutic agents, including thiotepa, inhibit plasma pseudocholinesterase by 35%  
to 70%. The action of succinyl-choline can be prolonged by 5 to 15 minutes.  
Thiotepa must not be concurrently administered with cyclophosphamide when both medicinal  
products are present in the same conditioning treatment. TEPADINA® must be delivered after the  
completion of any cyclophosphamide infusion.  
The concomitant use of thiotepa and other myelosuppressive or myelotoxic agents (i.e.  
cyclophosphamide, melphalan, busulfan, fludarabine, treosulfan) may potentiate the risk of  
haematologic adverse reactions due to overlapping toxicity profiles of these medicinal products.  
Interaction common to all cytotoxics  
Due to the increase of thrombotic risk in case of malignancy, the use of anticoagulative treatment is  
frequent. The high intra-individual variability of the coagulation state during malignancy, and the  
potential interaction between oral anticoagulants and anticancer chemotherapy require, if it is decided  
to treat the patient with oral anticoagulants, to increase the frequency of the INR (International  
Normalised Ratio) monitoring.  
9 / 22  
Product information for human medicinal products  
Pregnancy, lactation  
Pregnancy  
There are no data on the use of thiotepa during pregnancy. In pre-clinical studies thiotepa, as most  
alkylating agents, has been shown to cause embryo foetal lethality and teratogenicity (see Preclinical  
data section). Therefore, thiotepa is contraindicated during pregnancy.  
Women of childbearing potential have to use effective contraception during treatment and a  
pregnancy test should be performed before treatment is started.  
Lactation  
It is unknown whether thiotepa is excreted in human milk. Due to its pharmacological properties and  
its potential toxicity for breast-fed newborns/infants, breast-feeding is contraindicated during treatment  
with thiotepa.  
Fertility  
As most alkylating agents, thiotepa might impair male and female fertility.  
Male patients should seek for sperm cryopreservation before therapy is started and should not father  
a child while treated and during the year after cessation of treatment (see section Warning and  
precautions).  
Effects on ability to drive and use machines  
TEPADINA® has a major influence on the ability to drive and use machines. It is likely that certain  
adverse reactions of thiotepa like dizziness, headache and blurred vision could affect these functions.  
Undesirable effects  
The safety of thiotepa has been examined through a review of adverse events reported in published  
data from clinical trials. In these studies, a total of 6588 adult patients and 902 paediatric patients  
received thiotepa for conditioning treatment prior to haematopoietic progenitor cell transplantation.  
Serious toxicities involving the haematologic, hepatic and respiratory systems were considered as  
expected consequences of the conditioning regimen and transplant process. These include infection  
and Graft-versus host disease (GvHD) which, although not directly related, were the major causes of  
morbidity and mortality, especially in allogeneic HPCT.  
The most frequently adverse reactions reported in the different conditioning treatments including  
thiotepa are: infections, cytopenia, acute GvHD and chronic GvHD, gastrointestinal disorders,  
haemorrhagic cystitis, mucosal inflammation.  
Leukoencephalopathy  
10 / 22  
Product information for human medicinal products

Reporting suspected adverse reactions after authorisation of the medicinal product is very important.  
It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare  
professionals are asked to report any suspected adverse reactions online via the ElViS portal  
(Electronic Vigilance System). You can obtain information about this at www.swissmedic.ch.  
Overdose  
The most important adverse reactions expected in case of overdose is myeloablation and  
pancytopenia.  
There is no known antidote for thiotepa.  
The haematological status needs to be closely monitored and vigorous supportive measures instituted  
as medically indicated.  
Properties/Effects  
ATC code  
L01AC01  
Pharmacotherapeutic group: Antineoplastic agents, alkylating agents  
Mechanism of action  
Thiotepa is a polyfunctional cytotoxic agent related chemically and pharmacologically to the nitrogen  
mustard. The radiomimetic action of thiotepa is believed to occur through the release of ethylene  
imine radicals that, as in the case of irradiation therapy, disrupt the bonds of DNA, e.g. by alkylation of  
guanine at the N-7, breaking the linkage between the purine base and the sugar and liberating  
alkylated guanine.

Clinical efficacy  
The conditioning treatment must provide cytoreduction and ideally disease eradication. Thiotepa has  
marrow ablation as its dose-limiting toxicity, allowing significant dose escalation with the infusion of  
autologous HPCT. In allogeneic HPCT, the conditioning treatment must be sufficiently  
immunosuppressive and myeloablative to overcome host rejection of the graft. Due to its highly  
myeloablative characteristics, thiotepa enhances recipient immunosuppression and myeloablation,  
thus strengthening engraftment; this compensates for the loss of the GvHD-related GvL effects. As  
alkylating agent, thiotepa produces the most profound inhibition of tumour cell growth in vitro with the  
smallest increase in medicinal product concentration. Due to its lack of extramedullary toxicity despite  
dose escalation beyond myelotoxic doses, thiotepa has been used for decades in combination with  
other chemotherapy medicinal products prior to autologous and allogeneic HPCT.  
The results of published clinical studies supporting the efficacy of thiotepa are summarised:  
Autologous HPCT  
Haematological diseases  
Engraftment: Conditioning treatments including thiotepa have proved to be myeloablative.  
Disease Free Survival (DFS): An estimated 43% at five years has been reported, confirming that  
conditioning treatments containing thiotepa following autologous HPCT are effective therapeutic  
strategies for treating patients with haematological diseases.  
Relapse: In all conditioning treatments containing thiotepa, relapse rates at more than 1 year have  
been reported as being 60% or lower, which was considered by the physicians as the threshold to  
prove efficacy. In some of the conditioning treatments evaluated, relapse rates lower than 60% have  
also been reported at 5 years.  
Overall Survival (OS): OS ranged from 29% to 87% with a follow-up ranging from 22 up to 63 months.  
Regimen Related Mortality (RRM) and Transplant Related Mortality (TRM): RRM values ranging from  
2.5% to 29% have been reported. TRM values ranged from 0% to 21% at 1 year, confirming the  
safety of the conditioning treatment including thiotepa for autologous HPCT in adult patients with  
haematological diseases.  
Solid tumours  
Engraftment: Conditioning treatments including thiotepa have proved to be myeloablative.  
Disease Free Survival (DFS): Percentages reported with follow-up periods of more than 1 year  
confirm that conditioning treatments containing thiotepa following autologous HPCT are effective  
choices for treating patients with solid tumours.  
Relapse: In all conditioning treatments containing thiotepa, relapse rates at more than 1 year have  
been reported as being lower than 60%, which was considered by the physicians as the threshold to  
prove efficacy. In some cases, relapse rates of 35% and of 45% have been reported at 5 years and 6  
16 / 22  
Product information for human medicinal products  
years respectively.  
Overall Survival: OS ranged from 30% to 87% with a follow-up ranging from 11.7 up to 87 months.  
Regimen Related Mortality (RRM) and Transplant Related Mortality (TRM): RRM values ranging from  
0% to 2% have been reported. TRM values ranged from 0% to 7.4% confirming the safety of the  
conditioning treatment including thiotepa for autologous HPCT in adult patients with solid tumours.  
Allogeneic HPCT  
Haematological diseases  
Engraftment: Engraftment has been achieved (92%-100%) in all reported conditioning treatments and  
it was considered to occur at the expected time. Therefore it can be concluded that conditioning  
treatments including thiotepa are myeloablative.  
GvHD (graft versus host disease): all conditioning treatments evaluated assured a low incidence of  
acute GvHD grade III-IV (from 4% to 24%).  
Disease Free Survival (DFS): Percentages reported with follow-up periods of more than 1 year and up  
to 5 years confirm that conditioning treatments containing thiotepa following allogeneic HPCT are  
effective choices for treating patients with haematological diseases.  
Relapse: In all conditioning treatments containing thiotepa, relapse rates at more than 1 year have  
been reported as being lower than 40% (which was considered by the physicians as the threshold to  
prove efficacy). In some cases, relapse rates lower than 40% have also been reported at 5 years and  
10 years.  
Overall Survival: OS ranged from 31% to 81% with a follow-up ranging from 7.3 up to 120 months.  
Regimen Related Mortality (RRM) and Transplant Related Mortality (TRM): low values have been  
reported, confirming the safety of the conditioning treatments including thiotepa for allogeneic HPCT  
in adults patients with haematological diseases.  
Safety and efficacy in paediatric patients  
Autologous HPCT  
Solid tumours  
Engraftment: It has been achieved with all reported conditioning regimens including thiotepa.  
Disease Free Survival (DFS): With a follow-up of 36 to 57 months, DFS ranged from 46% to 70% in  
the reported studies. Considering that all patients were treated for high risk solid tumours, DFS results  
confirm that conditioning treatments containing thiotepa following autologous HPCT are effective  
therapeutic strategies for treating paediatric patients with solid tumours.  
Relapse: In all the reported conditioning regimens containing thiotepa, relapse rates at 12 to 57  
months ranged from 33% to 57%. Considering that all patients suffer of recurrence or poor prognosis  
solid tumours, these rates support the efficacy of conditioning regimens based on thiotepa.  
Overall Survival (OS): OS ranged from 17% to 84% with a follow-up ranging from 12.3 up to 99.6  
17 / 22  
Product information for human medicinal products  
months.  
Regimen Related Mortality (RRM) and Transplant Related Mortality (TRM): RRM values ranging from  
0% to 26.7% have been reported. TRM values ranged from 0% to 18% confirming the safety of the  
conditioning treatments including thiotepa for autologous HPCT in paediatric patients with solid  
tumours.  
Allogeneic HPCT  
Haematological diseases  
Engraftment: It has been achieved with all evaluated conditioning regimens including thiotepa with a  
success rate of 96% - 100%. The haematological recovery is in the expected time.  
Disease Free Survival (DFS): Percentages of 40% - 75% with follow-up of more than 1 year have  
been reported. DFS results confirm that conditioning treatment containing thiotepa following  
allogeneic HPCT are effective therapeutic strategies for treating paediatric patients with  
haematological diseases.  
Relapse: In all the reported conditioning regimens containing thiotepa, the relapse rate was in the  
range of 15% - 44%. These data support the efficacy of conditioning regimens based on thiotepa in all  
haematological diseases.  
Overall Survival (OS): OS ranged from 50% to 100% with a follow-up ranging from 9.4 up to 121  
months.  
Regimen Related Mortality (RRM) and Transplant Related Mortality (TRM): RRM values ranging from  
0% to 2.5% have been reported. TRM values ranged from 0% to 30% confirming the safety of the  
conditioning treatment including thiotepa for allogeneic HPCT in paediatric patients with  
haematological diseases.  
Pharmacokinetics  
Absorption  
Thiotepa is unreliably absorbed from the gastrointestinal tract: acid instability prevents thiotepa from  
being administered orally.  
Distribution  
Thiotepa is a highly lipophilic compound. After intravenous administration, plasma concentrations of  
the active substance fit a two compartment model with a rapid distribution phase. The volume of  
distribution of thiotepa is large and it has been reported as ranging from 40.8 l/m2 to 75 l/m2, indicating  
distribution to total body water. The apparent volume of distribution of thiotepa appears independent  
of the administered dose. The fraction unbound to proteins in plasma is 70-90%; insignificant binding  
of thiotepa to gamma globulin and minimal albumin binding (10-30%) has been reported.  
18 / 22  
Product information for human medicinal products  
After intravenous administration, CSF medicinal product exposure is nearly equivalent to that  
achieved in plasma; the mean ratio of AUC in CSF to plasma for thiotepa is 0.93. CSF and plasma  
concentrations of TEPA, the first reported active metabolite of thiotepa, exceed the concentrations of  
the parent compound.  
Metabolism  
Thiotepa undergoes rapid and extensive hepatic metabolism and metabolites could be detected in  
urine within 1 hour after infusion. The metabolites are active alkylating agents but the role they play in  
the antitumor activity of thiotepa remains to be elucidated. Thiotepa undergoes oxidative  
desulphuration via the cytochrome P450 CYP2B and CYP3A isoenzyme families to the major and  
active metabolite TEPA (triethylenephosphoramide). The total excreted amount of thiotepa and its  
identified metabolites accounts for 54-100% of the total alkylating activity, indicating the presence of  
other alkylating metabolites. During conversion of GSH conjugates to N-acetylcysteine conjugates,  
GSH, cysteinylglycine, and cysteine conjugates are formed. These metabolites are not found in urine,  
and, if formed, are probably excreted in bile or as intermediate metabolites rapidly converted into  
thiotepa-mercapturate.  
Elimination  
The total clearance of thiotepa ranged from 11.4 to 23.2 l/h/m2. The elimination half-life varied from  
1.5 to 4.1 hours. The identified metabolites TEPA, monochlorotepa and thiotepa-mercapturate are all  
excreted in the urine. Urinary excretion of thiotepa and TEPA is nearly complete after 6 and 8 hours  
respectively. The mean urinary recovery of thiotepa and its metabolites is 0.5% for the unchanged  
medicinal product and monochlorotepa, and 11% for TEPA and thiotepa-mercapturate.  
Linearity/non-linearity  
There is no clear evidence of saturation of metabolic clearance mechanisms at high doses of  
thiotepa.  
Kinetics in specific patient groups  
Hepatic impairment  
The effects of hepatic impairment on thiotepa metabolism and elimination have not been assessed.  
Renal impairment  
The effects of renal impairment on thiotepa elimination have not been assessed.  
Children and adolescents  
The pharmacokinetics of high dose thiotepa in children between 2 and 12 years of age do not appear  
to vary from those reported in children receiving 75 mg/m2 or adults receiving similar doses.

Product information for human medicinal products  
Preclinical data  
No conventional acute and repeat dose toxicity studies were performed.  
Thiotepa was shown to be genotoxic in vitro and in vivo, and carcinogenic in mice and rats.  
Thiotepa was shown to impair fertility and interfere with spermatogenesis in male mice, and to impair  
ovarian function in female mice. It was teratogenic in mice and in rats, and foeto lethal in rabbits.  
These effects were seen at doses lower than those used in humans.

Instructions for handling  
Preparation of TEPADINA®  
Procedures for proper handling and disposal of anticancer medicinal products must be considered. All  
transfer procedures require strict adherence to aseptic techniques, preferably employing a vertical  
laminar flow safety hood.  
As with other cytotoxic compounds, caution needs to be exercised in handling and preparation of  
TEPADINA® solutions to avoid accidental contact with skin or mucous membranes. Topical reactions  
associated with accidental exposure to thiotepa may occur. In fact, the use of gloves is recommended  
in preparing the solution for infusion. If thiotepa solution accidentally contacts the skin, the skin must  
be immediately and thoroughly washed with soap and water. If thiotepa accidentally contacts mucous  
membranes, they must be flushed thoroughly with water.  
Reconstitution  
TEPADINA® 15 mg must be reconstituted with 1.5 ml of sterile water for injection.  
Using a syringe fitted with a needle, aseptically withdraw 1.5 ml of sterile water for injection.  
TEPADINA® 100 mg must be reconstituted with 10 ml of sterile water for injection.  
Using a syringe fitted with a needle, aseptically withdraw 10 ml of sterile water for injection.  
Inject the content of the syringe into the vial through the rubber stopper.  
Remove the syringe and the needle and mix manually by repeated inversions.  
Only colourless solutions, without any particulate matter, must be used. Reconstituted solutions may  
occasionally show opalescence; such solutions can still be administered.  
Further dilution in the infusion bag  
The reconstituted solution is hypotonic and must be further diluted prior to administration with 500 ml  
sodium chloride 9 mg/ml (0.9%) solution for injection (1000 ml if the dose is higher than 500 mg) or  
with an appropriate volume of sodium chloride 9 mg/ml (0.9%) in order to obtain a final TEPADINA®  
concentration between 0.5 and 1 mg/ml.  
Administration  
TEPADINA® infusion solution should be inspected visually for particulate matter prior to  
administration. Solutions containing a precipitate should be discarded.  
Prior to and following each infusion, the indwelling catheter line should be flushed with approximately  
5 ml sodium chloride 9 mg/ml (0.9%) solution for injection.  
The infusion solution must be administered to patients using an infusion set equipped with a 0.2 µm in  
line polyethersulphone (PES) filter. Filtering does not alter solution potency.
