📖 What it is MedlinePlus · NLM

Topotecan injection is used to treat ovarian cancer (cancer that begins in the female reproductive organs where eggs are formed) and small cell lung cancer (a type of cancer that begins in the lungs) that have spread and did not improve after treatment with other medications. It is also used together with other medications to treat cervical cancer (cancer that begins in the opening of the uterus [womb]) that has not improved or has come back after other treatments. Topotecan is in a class of medications called topoisomerase type I inhibitors. It works by killing cancer cells.

Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS Interstitial Lung Disease (ILD): Fatal cases have occurred. Permanently discontinue if ILD confirmed. ( 5.2 ) Extravasation and Tissue Injury: Severe cases have occurred. If extravasation occurs, immediately stop administration and institute recommended management procedures. ( 5.3 ) Embryo-Fetal Toxicity: Can cause fetal harm. Advise patients of potential risk to the fetus and to use effectives contraception. ( 5.4 , 8.1 , 8.3 )

5.1Myelosuppression HYCAMTIN can cause severe myelosuppression. Single Agent Grade 4 neutropenia occurred in 78% of 879 patients, with a median duration of 7 days and was most common during Cycle 1 (58% of patients). Grade 4 neutropenia associated with infection occurred in 13% and febrile neutropenia occurred in 5%.

Sepsis occurred in 4% of patients and was fatal in 1%. Grade 4 thrombocytopenia occurred in 27%, with a median duration of 5 days. Grade 3 or 4 anemia occurred in 37% of patients.

Combination with Cisplatin Grade 4 neutropenia occurred in 48% and Grade 4 thrombocytopenia occurred in 7% of 147 patients. Grade 3 or 4 anemia occurred in 40% of patients. Topotecan can cause fatal typhlitis (neutropenic enterocolitis).

Consider the possibility of typhlitis in patients presenting with fever, neutropenia, and abdominal pain. Administer the first cycle of HYCAMTIN for injection only to patients with a baseline neutrophil count of greater than or equal to 1,500/mm 3 and a platelet count greater than or equal to 100,000/mm 3 . Monitor blood counts frequently during treatment.

Withhold and reduce dose of HYCAMTIN for injection based on neutrophil counts, platelet counts and hemoglobin levels [see Dosage and Administration (2.5)].

5.2Interstitial Lung Disease Interstitial lung disease (ILD), including fatalities, can occur with HYCAMTIN. Underlying risk factors include history of ILD, pulmonary fibrosis, lung cancer, thoracic radiation, and use of pneumotoxic drugs or colony stimulating factors. Monitor for pulmonary symptoms indicative of ILD. Permanently discontinue HYCAMTIN for injection if ILD is confirmed.

5.3Extravasation and Tissue Injury Extravasation, including severe cases, can occur with HYCAMTIN for injection. If signs or symptoms of extravasation occur, immediately stop administration of HYCAMTIN for injection and institute recommended management procedures [see Adverse Reactions (6.1)] .

5.4Embryo-Fetal Toxicity Based on animal data, HYCAMTIN can cause fetal harm when administered to a pregnant woman. Topotecan caused embryolethality, fetotoxicity, and teratogenicity in rats and rabbits when administered during organogenesis. Advise women of the potential risk to a fetus.

Advise females of reproductive potential to use effective contraception during treatment and for 6 months after the last dose of HYCAMTIN for injection. Advise males with a female partner of reproductive potential to use effective contraception during treatment with HYCAMTIN for injection and for 3 months after the last dose [see Use in Specific Populations (8.1, 8.3), Nonclinical Toxicology (13.1)] .

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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data in Warnings and Precautions reflect exposure to HYCAMTIN for injection from eight trials in which 879 patients with ovarian cancer or small cell lung cancer (SCLC) received HYCAMTIN for injection 1.5 mg/m 2 by intravenous infusion daily for 5 consecutive days, starting on Day 1 of a 21 day cycle and from one trial (Study GOG 0179) in which 147 patients with cervical cancer received HYCAMTIN for injection 0.75 mg/m 2 by intravenous infusion daily on Days 1, 2, and 3, with cisplatin 50 mg/m 2 by intravenous infusion on Day 1, of a 21-day cycle.

Ovarian Cancer The safety of HYCAMTIN for injection was evaluated in a randomized trial conducted in 226 patients with metastatic ovarian cancer (Study 039) [see Clinical Studies (14.1)] . Table 1 shows the incidence of Grade 3 and 4 hematologic and non-hematologic adverse reactions that occurred in patients receiving HYCAMTIN for injection. Table 1.

👥 Use in Specific Populations ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed. ( 8.2 )

8.1Pregnancy Risk Summary Based on animal data and its mechanism of action, HYCAMTIN can cause fetal harm when administered to a pregnant woman. There are no available clinical data on the use of HYCAMTIN in pregnancy. Topotecan caused embryolethality, fetotoxicity, and teratogenicity in rats and rabbits when administered during organogenesis at doses similar to the clinical dose (see Data) .

Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the background risk of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies. Data Animal Data In rabbits, an intravenous dose of 0.10 mg/kg/day [about equal to the 1.5 mg/m 2 clinical dose based on body surface area (BSA)] given on Days 6 through 20 of gestation caused maternal toxicity, embryolethality and reduced fetal body weight.

In the rat, an intravenous dose of 0.23 mg/kg/day (about equal to the 1.5 mg/m 2 clinical dose based on BSA) given for 14 days before mating through gestation Day 6 caused fetal resorption, microphthalmia, pre-implant loss, and mild maternal toxicity. Administration of an intravenous dose of 0.10 mg/kg/day (about half the 1.5 mg/m 2 clinical dose based on BSA) given to rats on Days 6 through 17 of gestation caused an increase in post-implantation mortality. This dose also caused an increase in total fetal malformations.

The most frequent malformations were of the eye (microphthalmia, anophthalmia, rosette formation of the retina, coloboma of the retina, ectopic orbit), brain (dilated lateral and third ventricles), skull, and vertebrae.

8.2Lactation Risk Summary There are no data on the presence of topotecan or its metabolites in human milk or their effects on the breastfed infant or on milk production. Lactating rats excrete high concentrations of topotecan in milk (see Data) . Because of the potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment with HYCAMTIN for injection and for 1 week after the last dose.

Data Following intravenous administration of topotecan to lactating rats at a dose of 4.72 mg/m 2 (about twice the 1.5 mg/m 2 clinical dose based on BSA) to lactating rats, topotecan was excreted into milk at concentrations up to 48-fold higher than those in plasma.

8.1Pregnancy Risk Summary Based on animal data and its mechanism of action, HYCAMTIN can cause fetal harm when administered to a pregnant woman. There are no available clinical data on the use of HYCAMTIN in pregnancy. Topotecan caused embryolethality, fetotoxicity, and teratogenicity in rats and rabbits when administered during organogenesis at doses similar to the clinical dose (see Data) .

Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the background risk of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies. Data Animal Data In rabbits, an intravenous dose of 0.10 mg/kg/day [about equal to the 1.5 mg/m 2 clinical dose based on body surface area (BSA)] given on Days 6 through 20 of gestation caused maternal toxicity, embryolethality and reduced fetal body weight.

In the rat, an intravenous dose of 0.23 mg/kg/day (about equal to the 1.5 mg/m 2 clinical dose based on BSA) given for 14 days before mating through gestation Day 6 caused fetal resorption, microphthalmia, pre-implant loss, and mild maternal toxicity. Administration of an intravenous dose of 0.10 mg/kg/day (about half the 1.5 mg/m 2 clinical dose based on BSA) given to rats on Days 6 through 17 of gestation caused an increase in post-implantation mortality. This dose also caused an increase in total fetal malformations.

The most frequent malformations were of the eye (microphthalmia, anophthalmia, rosette formation of the retina, coloboma of the retina, ectopic orbit), brain (dilated lateral and third ventricles), skull, and vertebrae.

🆘 Overdosage 54 words ▾

10 OVERDOSAGE Overdoses (up to 10-fold of the recommended dose) have occurred in patients receiving intravenous topotecan. The primary complication of overdosage is myelosuppression. Elevated hepatic enzymes, mucositis, gastrointestinal toxicity, and skin toxicity have occurred with overdosages. If an overdose is suspected, monitor the patient closely for myelosuppression and institute supportive-care measures as appropriate.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Topoisomerase I relieves torsional strain in DNA by inducing reversible single-strand breaks. Topotecan binds to the topoisomerase I‑DNA complex and prevents re-ligation of these single-strand breaks. The cytotoxicity of topotecan is thought to be due to double-strand DNA damage produced during DNA synthesis, when replication enzymes interact with the ternary complex formed by topotecan, topoisomerase I, and DNA.

Mammalian cells cannot efficiently repair these double-strand breaks.

12.3Pharmacokinetics Following administration of HYCAMTIN for injection at doses of 0.5 to 1.5 mg/m 2 (0.1 to 0.3 times the recommended single agent dose) administered as a 30-minute infusion, area under the curve (AUC) increases proportionally with dose. Distribution Protein binding of topotecan is approximately 35%. Elimination The terminal half-life of topotecan is 2 to 3 hours following intravenous administration.

Metabolism Topotecan undergoes a reversible pH-dependent hydrolysis of its pharmacologically active lactone moiety. At pH less than or equal to 4, the lactone is exclusively present, whereas the ring-opened hydroxy-acid form predominates at physiologic pH. Topotecan is metabolized to an N-demethylated metabolite in vitro.

The mean metabolite: parent AUC ratio was about 3% for total topotecan and topotecan lactone following intravenous administration. Excretion The overall recovery of total topotecan and its N-desmethyl metabolite in urine and feces over 9 days averaged 73% ± 2% following an intravenous dose. Mean values of 51% ± 3% as total topotecan and 3% ± 1% as N-desmethyl topotecan were excreted in the urine.

Fecal elimination of total topotecan accounted for 18% ± 4% while fecal elimination of N-desmethyl topotecan was 1.7% ± 0.6%. An O-glucuronidation metabolite of topotecan and N-desmethyl topotecan has been identified in the urine. Specific Populations No clinically significant differences in the pharmacokinetics of topotecan were observed based on age, sex, or hepatic impairment following intravenous administration.

Patients with Renal Impairment Compared to patients with CLcr (calculated by the Cockcroft-Gault method using ideal body weight) greater than 60 mL/min, plasma clearance of topotecan lactone decreased by 33% in patients with CLcr 40-60 mL/min and decreased 65% in patients with CLcr 20-39 mL/min. The effect on topotecan pharmacokinetics in patients with CLcr less than 20 mL/min is unknown [see Dosage and Administration (2.6)] . Drug Interaction Studies Clinical Studies No clinically significant changes in topotecan pharmacokinetics were observed when coadministered cisplatin.

No clinically significant changes in the pharmacokinetics of free platinum were observed in patients coadministered cisplatin with topotecan. In Vitro Studies Topotecan does not inhibit CYP1A2, CYP2A6, CYP2C8/9, CYP2C19, CYP2D6, CYP2E, CYP3A, or CYP4A or dihydropyrimidine dehydrogenase.

14 CLINICAL STUDIES

14.1Ovarian Cancer The efficacy of HYCAMTIN for injection was evaluated in two clinical trials of 223 patients with metastatic ovarian cancer. All patients had disease that had recurred on, or was unresponsive to, a platinum-containing regimen. Patients in these trials received an initial dose of 1.5 mg/m 2 as an intravenous infusion for 5 consecutive days, starting on Day 1 of a 21-day cycle.

One trial (Study 039) was a randomized trial of 112 patients who received HYCAMTIN for injection and of 114 patients who received paclitaxel (175 mg/m 2 intravenously over 3 hours on Day 1 of a 21-day cycle). All patients had recurrent ovarian cancer after a platinum-containing regimen or had not responded to at least 1 prior platinum-containing regimen. Patients who did not respond to the trial therapy, or who progressed, could be given the alternative treatment.

The efficacy outcome measures were overall response rate, response duration, time to progression, and overall survival (OS). The results of the trial did not show statistically significant improvements in response rates, response duration, time to progression, and OS as shown in Table 4. Table 4.

Efficacy Results in Ovarian Cancer in Study 039 Abbreviation: CI, confidence interval. a The calculation for response duration was based on the interval between first response and time to progression. Parameters HYCAMTIN for Injection (n = 112) Paclitaxel (n = 114) Overall response rate (95% CI) 21% (13%, 28%) 14% (8%, 20%) Complete response rate 5% 3% Partial response rate 16% 11% Response duration a (months) Median (95% CI) 6 (5.1, 7.6) 5 (3.7, 7.8) Time to progression (months) Median (95% CI) 4.4 (2.8, 5.4) 3.4 (2.7, 4.2) Hazard ratio (95% CI) 0.76 (0.57, 1.02) Overall survival (months) Median (95% CI) 14.5 (10.7, 16.5) 12.2 (9.7, 15.8) Hazard ratio (95% CI) 0.97 (0.71, 1.34) The median time to response was 7.6 weeks (3.1 weeks to 5 months) with HYCAMTIN for injection compared with 6 weeks (2.4 weeks to 4.1 months) with paclitaxel.

In the cross-over phase, 13% of 61 patients who received HYCAMTIN after paclitaxel had a partial response and 10% of 49 patients who received paclitaxel after HYCAMTIN had a response (2 complete responses). HYCAMTIN for injection was active in ovarian cancer patients who had developed resistance to platinum-containing therapy, defined as tumor progression while on, or tumor relapse within 6 months after completion of, a platinum-containing regimen. One complete and 6 partial responses were seen in 60 patients, for a response rate of 12%.

In the same trial, there were no complete responders and 4 partial responders on the paclitaxel arm, for a response rate of 7%. HYCAMTIN for injection was also studied in an open-label, non-comparative trial in 111 patients with recurrent ovarian cancer after treatment with a platinum-containing regimen, or who had not responded to 1 prior platinum-containing regimen. The response rate was 14% (95% CI: 7%, 20%).

The median duration of response was 5 months (4.6 weeks to 9.6 months). The time to progression was 2.6 months (5 days to 1.4 years). The median survival was 1.3 years (1.4 weeks, to 2.2 years).

14.2Small Cell Lung Cancer (SCLC) The efficacy of HYCAMTIN for injection was evaluated in 426 patients with recurrent or progressive small cell lung cancer (SCLC) in a randomized, comparative trial and in 3 single-arm trials. Randomized Comparative Trial In a randomized, comparative trial, 211 patients were randomized 1:1 to receive HYCAMTIN for injection (1.5 mg/m 2 once daily intravenously for 5 days starting on Day 1 of a 21-day cycle) or CAV (cyclophosphamide 1,000 mg/m 2 , doxorubicin 45 mg/m 2 , vincristine 2 mg administered sequentially on Day 1 of a 21-day cycle).

All patients were considered sensitive to first-line chemotherapy (responders who then subsequently progressed greater than or equal to 60 days after completion of first-line therapy). A total of 77% of patients treated with HYCAMTIN… [Excerpted — this section continues on DailyMed.]

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenicity testing of topotecan has not been performed. Topotecan is known to be genotoxic to mammalian cells and is a probable carcinogen. Topotecan was mutagenic to L5178Y mouse lymphoma cells and clastogenic to cultured human lymphocytes with and without metabolic activation.

It was also clastogenic to mouse bone marrow. Topotecan did not cause mutations in bacterial cells. Topotecan given to female rats prior to mating at an intravenous dose of 1.4 mg/m 2 [about equal to the clinical dose based on body surface area (BSA)] caused superovulation possibly related to inhibition of follicular atresia.

This dose given to pregnant female rats also caused increased pre-implantation loss. Studies in dogs given at an intravenous dose of 0.4 mg/m 2 (about 0.25 times the clinical dose based on BSA) of topotecan daily for a month suggest that treatment may cause an increase in the incidence of multinucleated spermatogonial giant cells in the testes.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Novartis Pharmaceuticals Corporation. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Novartis Pharmaceuticals Corporation is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J9351 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
