• Small cell lung cancer sensitive disease after failure of first-line chemotherapy. In clinical studies
submitted to support approval, sensitive disease was defined as disease responding to
chemotherapy but subsequently progressing at least 60 days (in the Phase 3 study) or at least 90
days (in the Phase 2 studies) after chemotherapy.
• HYCAMTIN in combination with cisplatin is indicated for the treatment of patients with
histologically confirmed Stage IV-B, recurrent, or persistent carcinoma of the cervix, which is not
amenable to curative treatment with surgery and/or radiation therapy.
For efficacy data see Clinical Studies.
DOSAGE REGIMEN AND ADMINISTRATION
Hycamtin must be reconstituted and further diluted before use (see section INSTRUCTIONS FOR
USE AND HANDLING).
Prior to administration of the first course of Hycamtin, patients must have a baseline neutrophil count
of more than or equal to 1.5 x 109/L, a platelet count of more than or equal to 100 x 109/L and a
hemoglobin level of more than or equal to 9 g/dL (after transfusion if necessary).

1Populations - Adults and Elderly
Ovarian and small cell lung carcinoma Initial dose
The recommended dose of Hycamtin is 1.5 mg/m2 by intravenous infusion over 30 minutes daily for 5
consecutive days, starting on day 1 of a 21-day course. In the absence of tumor progression, a
minimum of 4 courses is recommended because tumor response may be delayed. The median time
to response in three ovarian clinical trials was 7.6 to 11.7 weeks and median time to response in four
small cell lung cancer trials was 6.1 weeks.
Subsequent doses
Hycamtin should not be re-administered unless the neutrophil count is more than or equal to 1 x
109/L, the platelet count is more than or equal to 100 x 109/L, and the hemoglobin level is more than
or equal to 9 g/dL (after transfusion if necessary).
Standard oncology practice for the management of neutropenia is either to administer Hycamtin with
other medications (e.g. G-CSF) or to reduce the dose to maintain neutrophil counts.
If dose reduction is chosen for patients who experience severe neutropenia (neutrophil count less
than or equal to 0.5 x 109/L) for 7 days or more, or severe neutropenia associated with fever or
infection, or who have had treatment delayed due to neutropenia, the dose should be reduced by
0.25 mg/m2/day to 1.25 mg/m2/day (or subsequently down to 1.0 mg/m2/day if necessary).
Doses should be similarly reduced if the platelet count falls below 25 x 109/L.
In clinical trials, topotecan powder for i.v. infusion was discontinued if the dose had to be reduced
below 1.0 mg/m2.
Cervical Cancer
Initial dose
The recommended dose of Hycamtin is 0.75 mg/m2 administered as a 30 minute intravenous infusion
daily on days 1, 2 and 3. Cisplatin is administered as an intravenous infusion on day 1 at a dose of
50 mg/m2 and following the Hycamtin dose. This treatment schedule is repeated every 21 days for 6
courses or until disease progression.
Subsequent doses
Hycamtin should not be re-administered unless the neutrophil count is more than or equal to
1.5 x 109/L, the platelet count is more than or equal to 100 x 109/L, and the haemoglobin level is more
than or equal to 9 g/dL (after transfusion if necessary).
Standard oncology practice for the management of neutropenia is either to administer Hycamtin with
other medications (e.g. G-CSF) or to reduce the dose to maintain neutrophil counts.
If dose reduction is chosen for patients who experience severe neutropenia (neutrophil count less
than 0.5 x 109/L) for 7 days or more, or severe neutropenia associated with fever or infection or who
have had treatment delayed due to neutropenia, the dose should be reduced by 20% to 0.60 mg/m2
for subsequent courses (or subsequently down to 0.45 mg/m2/day).
Doses should be similarly reduced if the platelet count falls below 25 x 109/L.
Dosage in Combination
Dose adjustment may be necessary if Hycamtin is administered in combination with other cytotoxic
agents (see section INTERACTIONS).
Special Populations
Pediatric patients (below 18 years)
Due to limited data on efficacy and safety in the paediatric population, no recommendation for
treatment of children with Hycamtin can be given.
India pack insert dtd 14 Nov 18 based on IPL dtd 10 Sep 18
2Geriatric patients (65 years or above)
No dosage adjustment appears to be needed in the elderly, other than adjustments related to renal
function.
Renal impairment
Monotherapy
No dosage adjustment appears to be required for treating patients with mild renal impairment
(creatinine clearance 40 to 60 mL/min.). Dosage adjustment to 0.75 mg/m2 is recommended for
patients with a creatinine clearance of 20 to 39 mL/min. Insufficient data are available in patients with
severe renal impairment to provide a dosage recommendation. Advice on dosing of Hycamtin for
patients with moderate renal impairment (20 to 39 mL/min) is based on studies involving patients with
advanced cancer.
Combination therapy
It is recommended that Hycamtin in combination with cisplatin for the treatment of cervical cancer only
be initiated in patients with serum creatinine less than or equal to 1.5 mg/dL. If, during
Hycamtin/cisplatin combination therapy serum creatinine exceeds 1.5 mg/dL, it is recommended that
the full prescribing information be consulted for any advice on cisplatin dose reduction/continuation. If
cisplatin is discontinued, there are insufficient data regarding continuing monotherapy with topotecan
in patients with cervical cancer.
Hepatic impairment
Monotherapy
No dosage adjustment appears to be required for treating patients with impaired hepatic function
(serum bilirubin in the range 1.5 to 10 mg/dL).
CONTRAINDICATIONS
Hycamtin is contra-indicated in patients who
• have a history of severe hypersensitivity reactions to topotecan and/or its excipients
• are pregnant or breast-feeding (see section PREGNANCY, LACTATION, FEMALES AND MALES
OF REPRODUCTIVE POTENTIAL)
• already have severe bone marrow depression prior to starting first course, as evidenced by
baseline neutrophils less than 1.5 x 109/L and/or a platelet count of less than 100 x 109/L.
WARNINGS AND PRECAUTIONS
Hycamtin should be initiated under the direction of a physician experienced in the use of cytotoxic
agents.
Hematological toxicity is dose-related and full blood count including platelets should be monitored
regularly (see section DOSAGE REGIMEN AND ADMINISTRATION).
As with other cytotoxic drugs, Hycamtin can cause severe myelosuppression. Myelosuppression
leading to sepsis and fatalities due to sepsis have been reported in patients treated with Hycamtin
(see section ADVERSE DRUG REACTIONS).
Topotecan-induced neutropenia can cause neutropenic colitis. Fatalities due to neutropenic colitis
have been reported in clinical trials with topotecan. In patients presenting with fever, neutropenia, and
a compatible pattern of abdominal pain, the possibility of neutropenic colitis should be considered.
Hycamtin has been associated with reports of interstitial lung disease (ILD), some of which have been
fatal (see section ADVERSE DRUG REACTIONS). Underlying risk factors include history of ILD,
pulmonary fibrosis, lung cancer, thoracic exposure to radiation and use of pneumotoxic drugs and/or
colony stimulating factors. Patients should be monitored for pulmonary symptoms indicative of ILD
(e.g. cough, fever, dyspnea and/or hypoxia), and Hycamtin should be discontinued if a new diagnosis
of ILD is confirmed.
Dose adjustment may be necessary if Hycamtin is administered in combination with other cytotoxic
agents (see section INTERACTIONS).

3Driving and using machines
Caution should be observed when driving or operating machinery if fatigue and asthenia persist.
ADVERSE DRUG REACTIONS
In the intravenous topotecan studies for treatment of ovarian cancer, prolonged use (more than six
courses) of topotecan was not associated with an increase in the rate of haematologic toxicity.
The following frequencies are estimated at the standard recommended doses of topotecan according
to indication and formulation.
Further information regarding incidence and grade of toxicity is presented in the Clinical Studies
section.
Adverse drug reactions from clinical trials (Table 1) are listed by MedDRA system organ class. Within
each system organ class, the adverse drug reactions are ranked by frequency, with the most frequent
reactions first. Within each frequency grouping, adverse drug reactions are presented in order of
decreasing seriousness. In addition, the corresponding frequency category for each adverse drug
reaction is based on the following convention (CIOMS III): very common (≥1/10); common (≥1/100 to
<1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000), not
known (cannot be estimated from the available data).

5Adverse drug reactions from spontaneous reports and literature cases (frequency not known)
The following adverse drug reactions have been derived from post-marketing experience with Hycamtin
via spontaneous case reports and literature cases. Because these reactions are reported voluntarily
from a population of uncertain size, it is not possible to reliably estimate their frequency, which is
therefore categorized as not known. Adverse drug reactions are listed according to system organ
classes in MedDRA. Within each system organ class, ADRs are presented in order of decreasing
seriousness.

INTERACTIONS
As with other myelosuppressive cytotoxic agents, greater myelosuppression is likely to be seen when
Hycamtin is used in combination with other cytotoxic agents (e.g. paclitaxel or etoposide) thereby
necessitating dose reduction. However, in combining with platinum agents (e.g. cisplatin or
carboplatin), there is a distinct sequence-dependent interaction depending on whether the platinum
agent is given on day 1 or 5 of the topotecan dosing. If the platinum agent is given on day 1 of the
topotecan dosing, lower doses of each agent must be given compared to the doses which can be given
if the platinum agent is given on day 5 of the topotecan dosing (see section DOSAGE REGIMEN AND
ADMINISTRATION).
When topotecan (0.75 mg/m2/day for five consecutive days) and cisplatin (60 mg/m2/day on Day 1)
were administered intravenously in 13 patients with ovarian cancer, mean topotecan plasma clearance
on Day 5 was slightly reduced compared to values on Day 1. As a result, systemic exposure of total
topotecan, as measured by AUC and Cmax, on Day 5 were increased by 12% (95% CI; 2%, 24%) and
23% (95% CI; —7%, 63%), respectively. No pharmacokinetic data are available following topotecan
(0.75 mg/m2/day for three consecutive days) and cisplatin (50 mg/m2/day on Day 1) in patients with
cervical cancer.
Topotecan does not inhibit human cytochrome P450 enzymes (see section PHARMACOKINETICS). In
population studies, the co-administration (in separate lines or by separate routes) of granisetron,
ondansetron, morphine or corticosteroids did not appear to have a significant effect on the
pharmacokinetics of intravenously administered topotecan.
Topotecan is a substrate for both ABCG2 (BCRP) and ABCB1 (P-glycoprotein). Inhibitors of ABCB1
and ABCG2 (e.g. elacridar) administered with oral topotecan increased topotecan exposure. The effect
of elacridar on the pharmacokinetics of intravenous topotecan was much less than the effect on oral
topotecan.

6PREGNANCY, LACTATION, FEMALES AND MALES OF REPRODUCTIVE POTENTIAL
Pregnancy
Risk summary
Hycamtin is contraindicated during pregnancy (see section CONTRAINDICATIONS).
Based on animal data, Hycamtin can cause fetal harm when administered to a pregnant woman.
Topotecan caused embryotoxicity, fetotoxicity, and teratogenicity when administered in rats and rabbits at
doses lower than the clinical dose [see Animal data].
Animal data
As with other cytotoxic agents, topotecan was also shown to cause embryo-fetal toxicity when given to
rats (0.59 mg/m2/day) and rabbits (1.25 mg/m2/day) at doses less than the clinical i.v. dose in humans
(1.5 mg/m2/day). A dose of 0.59 mg/m2 was teratogenic in rats (predominantly effects of the eye, brain,
skull and vertebrae).
Lactation
Risk summary
Hycamtin is contra-indicated during breast-feeding (see section CONTRAINDICATION).
It is not known whether this drug is present in human milk; however, topotecan is transfered into rat milk
at high concentrations [see Animal data]. Because of the potential for serious adverse reactions in
nursing infants with topotecan, nursing mothers should be advised to discontinue breastfeeding during
treatment with Hycamtin.
Animal Data
Following intravenous administration of topotecan to lactating rats at a dose of 4.72 mg/m2 (about twice
the clinical dose on a mg/m2 basis), topotecan was transfered into milk at concentrations up to 48-fold
higher than those in plasma . The concentration in milk declined to 2-fold higher than that in plasma at
72 h.
Females and males of reproductive potential
Females of reproductive potential should be advised to avoid becoming pregnant during therapy with
Hycamtin and to inform the treating physician immediately should this occur.
Pregnancy testing
Pregnancy status should be verified for females of reproductive potential prior to starting treatment with
Hycamtin.
Contraception
Females:
As with all cytotoxic drugs, females of reproductive potential should use effective contraception (methods
that result in less than 1 % pregnancy rates) during treatment with Hycamtin
Males:
Because of genotoxic potential, male patients should use condoms during sexual intercourse while taking
Hycamtin and for at least 3 months after stopping treatment with Hycamtin.
Infertility
No effects on male or female fertility have been observed in reproductive toxicity studies in rats (see
section NON-CLINICAL SAFETY DATA). However, as with other cytotoxic medicinal products,
topotecan is genotoxic and effects on fertility, including male fertility, cannot be excluded.

7OVERDOSAGE
Symptoms and Signs
Overdoses (up to 10 fold of the prescribed dose) have been reported in patients being treated with
intravenous topotecan. The primary complication of overdosage is bone marrow suppression. The
observed signs and symptoms for overdose are consistent with the known adverse reactions
associated with topotecan (see section ADVERSE DRUG REACTIONS). In addition, elevated hepatic
enzymes and mucositis have been reported following overdose.
Treatment
There is no known antidote for topotecan overdosage. Further management should be as clinically
indicated or as recommended by the national poisons centre, where available.
CLINICAL PHARMACOLOGY
Pharmacodynamics
Mechanism of Action
The anti-tumor activity of topotecan involves the inhibition of topoisomerase-I, an enzyme intimately
involved in DNA replication as it relieves the torsional strain introduced ahead of the moving
replication fork. Topotecan inhibits topoisomerase-I by stabilising the covalent complex of enzyme and
strand-cleaved DNA which is an intermediate of the catalytic mechanism. The cellular sequelae of
inhibition of topoisomerase-I by topotecan is the induction of protein-associated DNA single-strand
breaks.
Pharmacokinetics
Absorption
Not applicable for i.v.
Distribution
Topotecan has a high volume of distribution of about 132 L, approximately three times total body
water, and a relatively short half-life of two to three hours. Comparison of pharmacokinetic parameters
did not suggest any change in pharmacokinetics over the five days of dosing.
The binding of topotecan to plasma proteins was low (35%) and distribution between blood cells and
plasma was homogeneous.
Plasma clearance and volume of distribution were found to be slightly higher in males than females.
However, differences were found to be similar in magnitude to differences in body surface area.
Metabolism
A major route of inactivation of topotecan is a reversible pH-dependent ring opening to the inactive
carboxylate form.
Metabolism accounts for less than 10% of the elimination of topotecan. A N-desmethyl metabolite was
found in urine, plasma, and faeces. Following oral administration the mean metabolite:parent AUC
ratio was less than 10% for both total topotecan and topotecan lactone. An O-glucuronide of
topotecan and N-desmethyl topotecan has been identified in the urine.
India pack insert dtd 14 Nov 18 based on IPL dtd 10 Sep 18
8In vitro, topotecan did not inhibit human cytochrome P450 enzymes CYP1A2, CYP2A6, CYP2C8/9,
CYP2C19, CYP2D6, CYP2E, CYP3A, or CYP4A nor did it inhibit the human cytosolic enzymes
dihydropyrimidine dehydrogenase or xanthine oxidase.
Elimination
Following i.v. administration, the plasma concentrations decline bi-exponentially. The
pharmacokinetics of i.v. topotecan are approximately dose proportional. There is little or no
accumulation of topotecan with repeated daily dosing, and there is no evidence of a change in the
pharmacokinetics with multiple dosing.
Following i.v. administration of topotecan at doses of 0.5 to 1.5 mg/m2 as a 30 minute infusion daily
for five days, topotecan demonstrated a high clearance (64 L/h), approximately 2/3 of liver blood flow.
Overall recovery of drug-related material following five daily doses of topotecan was 71 to 76% (i.v.) of
the administered dose. Approximately 51% was excreted as total topotecan and 2.5% was excreted
as N-desmethyl topotecan in the urine. Faecal elimination of total topotecan accounted for 18% of the
administered dose while faecal elimination of N-desmethyl topotecan was approximately 1.5%.
Overall, the N-desmethyl metabolite contributed a mean of less than 7% (range 4 to 9%) of the total
drug-related material accounted for in the urine and faeces. The topotecan-O-glucuronide and N-
desmethyl topotecan-O-glucuronide in the urine were less than or equal to 2% of the dose.
When given in combination with cisplatin (cisplatin day 1, topotecan days 1 to 5), the clearance of
topotecan was reduced on day 5 compared to day 1 (19.1 L/h/m2 compared to 21.3 L/h/m2) (see
section INTERACTIONS). In population studies, the co-administration of granisetron, ondansetron,
morphine or corticosteroids did not appear to have a significant effect on the pharmacokinetics of
topotecan.
Special Patient Populations
In a population study with i.v. topotecan, a number of factors including age, weight and ascites had no
significant effect on clearance (see section INTERACTIONS).
Pediatric patients (below 18 years)
The pharmacokinetics of topotecan in paediatrics was studied in paediatrics who had either received
a 24 hour continuous infusion of between 2 and 7.5 mg/m2 or a 72 hour continuous infusion of
between 0.75 and 1.95 mg/m2/day. In both studies the clearance was similar to that found in adults
using the same dosing regimens.
Renal impairment
Plasma clearance of i.v. topotecan in patients with renal impairment (creatinine clearance 40 to
60 ml/min.) decreased to about 67% compared with control patients. Volume of distribution was
slightly decreased and thus half-life only increased by 14%. In patients with moderate renal
impairment (creatinine clearance 20 to 39 ml/min) topotecan plasma clearance was reduced to 34%
of the value in control patients. Volume of distribution also decreased by about 25% which resulted in
an increase in mean half-life from 1.9 hours to 4.9 hours.
Hepatic impairment
Plasma clearance of topotecan lactone after i.v. administration in patients with hepatic impairment
(serum bilirubin in the range 1.5 to 10 mg/dL) decreased to about 67% when compared with a control
group of patients. Topotecan half-life was increased by about 30% but no clear change in volume of
distribution was observed. Total topotecan plasma clearance in patients with hepatic impairment only
decreased by about 10% compared with the control group of patients.
CLINICAL STUDIES
Small Cell Lung Carcinoma
In a comparative study (SK&F 104864/090) of i.v. topotecan and the treatment regimen CAV
(cyclophosphamide, doxorubicin, vincristine) in relapsed small cell lung carcinoma which was sensitive
to first line therapy, there was a numerically superior response rate with topotecan 22%
India pack insert dtd 14 Nov 18 based on IPL dtd 10 Sep 18
9(95% CI; 15, 30) versus CAV 15% (95% CI; 8, 22). All radiological responses were independently
verified. "Sensitivity" was defined as 3 months treatment-free interval; to facilitate recruitment this
was amended to 60 days treatment-free interval. The median duration of response (14 weeks for
topotecan and 15 weeks for CAV), time to progression (topotecan 13 weeks versus CAV 12 weeks)
and survival time (topotecan 25 weeks versus CAV 22 weeks) were similar for both treatments. Using
the Patient Symptom Assessment in Lung Cancer Scale, patients treated with topotecan reported
greater symptom relief improvement) over CAV for the following symptoms: dyspnea, cough, chest
pain, loss of appetite, interference with sleep, hoarseness, fatigue and interference with daily
activities, with significant results for dyspnea, hoarseness, fatigue and interference with daily
activities.
Hemoptysis was alleviated to a greater (but not statistically significant) extent in patients treated with
CAV. The time to worsening of the following symptoms was numerically greater (i.e. delayed
worsening) for topotecan treated patients than for CAV: dyspnea, loss of appetite, interference with
sleep, cough, interference with daily activity, hoarseness and fatigue, with significant results for
dyspnea and loss of appetite. Time to worsening for chest pain was similar for i.v. topotecan and CAV
treatments, and for hemoptysis numerically greater for CAV (30th May 1997 cut-off).
Efficacy data for study SKF104864/090 was updated based on a second clinical cut-off of the 20th
March 1998. Qualitatively the efficacy data remained unchanged with only minor numerical updates
for response rate, topotecan 24.3% versus CAV 18.3% and median survival, topotecan 25 weeks
versus CAV 24.77 weeks.
Ovarian carcinoma
In a comparative study (SK&F 104864/039) of i.v. topotecan (n=112) and i.v. paclitaxel (n=114) in
relapsed ovarian carcinoma, there was a numerically superior response rate with topotecan 20.5%
(95% CI; 13.1 to 28.0) versus paclitaxel 14% (95% CI; 7.7 to 20.4). The difference between
treatments was 6.5% (95% CI -3.3, 16.3). All radiological responses were independently verified.
The median duration of response (25.9 weeks for topotecan and 21.6 weeks for paclitaxel), median
time to progression (topotecan 18.9 weeks (95% CI 12.1, 23.6) versus paclitaxel 14.7 weeks (95% CI
11.9, 18.3) and median survival (topotecan 63.0 weeks (95% CI 46.6, 71.9) versus paclitaxel 53
weeks (95% CI 42.3, 68.7).
Note: All data denote values for ITT analysis population.
Cervical carcinoma
In a randomized, comparative phase III trial conducted by the Gynaecological Oncology Group (GOG
0179), topotecan plus cisplatin (n=147) was compared with cisplatin alone (n=146) for the treatment
of confirmed Stage IV-B, recurrent or persistent carcinoma of the cervix where curative treatment with
surgery and/or radiation was not considered appropriate. No patient had received primary
chemotherapy with cisplatin or any other cytotoxic agent. The overall response rate in the topotecan
plus cisplatin group of 24% was significantly higher (p=0.0073) than the 12% achieved in the cisplatin
alone group. The complete response rate in the topotecan plus cisplatin and cisplatin alone arms
were 10% and 3% respectively. This was associated with a longer progression-free survival of 4.6
(range 3.5 to 5.7) months versus 2.9 (range 2.6 to 3.5) months (p=0.026) and a longer overall survival
of 9.4 (range 7.9 to 11.9) months compared to 6.5 (range 5.8 to 8.8) months (p=0.033) in the
topotecan plus cisplatin arm compared to the cisplatin alone arm. The one year survival rate in the
topotecan plus cisplatin group was 40.4% (95% CI; 32.3, 48.5) compared to 28% (95% CI; 20.6, 35.4)
in the cisplatin alone group. Two year survival was 11.9 % (95% CI; 5.5, 18.3) and 7.1% (95% CI;
2.0, 12.2) for the two patient populations respectively. The secondary endpoint of health-related
quality of life (HrQoL) was assessed using the Functional Assessment of Cancer Therapy-Cervix
Cancer, Brief Pain Inventory as well as the UNISCALE. HrQoL assessments were made prior to
randomization, prior to cycles 2 and 5 of treatment and nine months post-randomisation. Compared
to cisplatin alone, the increased hematological toxicity seen with the combination of topotecan and
cisplatin did not significantly reduce the patient HrQoL outcomes.
Integrated safety data
Safety data is presented on an integrated data set of 631 patients with relapsed lung cancer and 523
patients with relapsed ovarian cancer administered 5583 courses of topotecan (see section
ADVERSE DRUG REACTIONS).

10Hematological
Neutropenia: Severe (neutrophil count less than 0.5 x 109/L) during course 1 was seen in 55% of the
patients and with duration greater than or equal to 7 days in 21% and overall in 76% of patients (39%
of courses). In association with severe neutropenia, fever or infection occurred in 11% of patients
during course 1 and overall in 18% of patients (5% of courses). Median time to onset of severe
neutropenia was nine days and the median duration was seven days. Severe neutropenia lasted
beyond seven days in 11% of courses overall. Among all patients treated in clinical trials (including
both those with severe neutropenia and those who did not develop severe neutropenia), 11% (4% of
courses) developed fever and 26% (9% of courses) developed infection. In addition, 5% of all
patients treated (1% of courses) developed sepsis.
Thrombocytopenia: Severe (platelets less than 25 x 109/L (as defined by v1 of CTC criteria)) in 25%
of patients (8% of courses); moderate (platelets between 25.0 and 50.0 x 109/L) in 25 % of patients
(15% of courses). Median time to onset of severe thrombocytopenia was Day 15 and the median
duration was 5 days. Platelet transfusions were given in 4% of courses. Reports of significant
sequelae associated with thrombocytopenia including fatalities due to tumor bleeds have been
infrequent.
Anemia: Moderate to severe (Hb less than 8.0 g/dl) in 37% of patients (14% of courses). Red cell
transfusions were given in 52% of patients (21% of courses).
Non-hematological
Frequently reported non-hematological effects were gastrointestinal such as nausea (52%), vomiting
(32%), and diarrhea (19%), constipation (9%) and stomatitis (15%). Severe (grade 3 or 4) nausea,

Total or pronounced alopecia was observed in 30% of patients and partial alopecia in 15% of patients.
Other events occurring in patients that were recorded as related or possibly related to topotecan
treatment were anorexia (13%), malaise (4%) and hyperbilirubinemia (1%).

NON-CLINICAL SAFETY DATA
Carcinogenicity and mutagenicity
The carcinogenic potential of topotecan has not been studied. In common with a number of other
cytotoxic agents, and resulting from its mechanism of action, topotecan is genotoxic to mammalian
cells (mouse lymphoma cells and human lymphocytes) in vitro and mouse bone marrow cells in vivo.
Reproductive toxicology
In reproductive toxicity studies with topotecan in rats, there was no effect on male or female fertility;
however, in females rats super-ovulation and slightly increased pre-implantation loss were observed
(see section FEMALES AND MALES OF REPRODUCTIVE POTENTIAL FOR REPRODUCTIVE
TOXICITY).
INCOMPATIBILITIES
None known.
