-
2 DOSAGE AND ADMINISTRATION
2.1 Premedication and Supportive Medications
Administer KYXATA in a setting where cardiopulmonary resuscitation medication and equipment are available [see Warnings and Precautions (5.1)].
Premedicate patients with antiemetics prior to each infusion of KYXATA for the prevention of nausea and vomiting. Continue antiemetics following infusion as needed [see Warnings and Precautions (5.3)].
2.2 Recommended Dosage
Initial Treatment of Advanced Ovarian Carcinoma with Cyclophosphamide
- KYXATA 300 mg/m2-OR-AUC of 4 mg/mL∙min to 6 mg/mL∙min* intravenously in combination with cyclophosphamide 600 mg/m2intravenously on Day 1 every 4 weeks for each cycle.
*Carboplatin Dose (mg) = Target Area Under the Curve (AUC) (mg/mL/min) x (GFR + 25). Glomerular filtration rate (GFR) is commonly calculated as estimated creatinine clearance (CLcr) using the Cockroft-Gault formula.
- Administer up to six cycles or until disease progression or unacceptable toxicity occurs.
Refer to cyclophosphamide prescribing information for additional information.
For older adults, calculate the dose based on AUC to reduce risk of severe adverse reactions.
Individualize the dose and dosing schedule of KYXATA based on the specific regimen administered, response to treatment, and patient risk factors [see Dosage and Administration (2.3, 2.4)].
Secondary Treatment of Advanced Ovarian Carcinoma as a Single Agent
- KYXATA 360 mg/m2-OR- AUC of 4 mg/mL∙min to 6 mg/mL∙min* intravenously on Day 1 every 4 weeks for each cycle until disease progression or unacceptable toxicity occurs.
* Carboplatin Dose (mg) = Target AUC (mg/mL/min) x (GFR + 25). GFR is commonly calculated as estimated creatinine clearance (CLcr) using the Cockroft-Gault formula.
For older adults, calculate the dose based on AUC to reduce risk of severe adverse reactions.
Individualize the dose and dosing schedule of KYXATA based on response to treatment and patient risk factors [see Dosage and Administration (2.3, 2.4)].
2.3 Dosage Modifications for Adverse Reactions
For a patients administered a dose based on body surface area as a single agent or combination, dosage modifications are shown in Table 1.

2.5 Preparation and Administration
KYXATA is a hazardous drug. Follow applicable handling and disposal procedures.1
Do not use needles or intravenous infusion sets containing aluminum; aluminum reacts with carboplatin causing precipitate formation and a loss of potency.
Visually inspect KYXATA vials prior to use. Discard solution if particulate matter or discoloration are observed.
KYXATA is supplied as a multiple-dose vial. After first use, store the partially used vial in the original carton at 20°C to 25°C (68°F to 77°F) and then discard after 28 days.
- Withdraw the calculated dose of KYXATA from the vial.
- Prior to administration, KYXATA can be further diluted to concentrations as low as 0.5 mg/mL with 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP.
- Diluted carboplatin solution for infusion when prepared as directed in an infusion bag should be used immediately, but may be stored at room temperature (20°C to 25°C) for a maximum of 8 hours. Discard KYXATA infusion solution 8 hours after dilution.
Administer KYXATA by intravenous infusion over 30 to 60 minutes.

5 WARNINGS AND PRECAUTIONS
5.1 Hypersensitivity Reactions
Hypersensitivity, including anaphylaxis, can occur in patients treated with KYXATA. Hypersensitivity reactions occurred in 2% of patients treated with carboplatin and included rash, urticaria, erythema, pruritus, bronchospasm, and hypotension. These adverse reactions may occur within minutes of administration and during any cycle. There is an increased risk of allergic reactions, including anaphylaxis, in patients previously exposed to platinum-based therapy or after 6 cycles of carboplatin [see Adverse Reactions (6.1)].
Monitor patients receiving KYXATA for hypersensitivity reactions. Ensure supportive equipment and medications are available to treat severe hypersensitivity reactions. Severe hypersensitivity reactions may require immediate discontinuation of KYXATA.
5.2 Myelosuppression
Myelosuppression (leukopenia, neutropenia, and thrombocytopenia) is dose-dependent may be severe, and can cause fatal infections or hemorrhage in patients treated with KYXATA.
Grade 3–4 neutropenia occurred in 16% of the patients treated with carboplatin as a single agent. Grade 3-4 thrombocytopenia occurred in 25% of patients with ovarian cancer. Febrile neutropenia may occur. Blood product transfusions were required in 26% (44% of pretreated) of patients with ovarian cancer treated with carboplatin as a single agent. Infectious and hemorrhagic complications each occurred in 5% of the patients treated with carboplatin as a single agent. Fatal adverse reactions occurred in less than 1% of patients treated with carboplatin as a single agent.
Patients with impaired kidney function are at increased risk of severe myelosuppression and may require dosage modifications [see Dosage and Administration (2.4) and Use in Specific Populations (8.6)].
Monitor complete blood counts prior to each cycle and as clinically indicated. If myelosuppression occurs, modify KYXATA dosage when required [see Dosage and Administration (2.3)].
5.3 Nausea and Vomiting
KYXATA can induce emesis, which can be more severe in patients previously receiving emetogenic therapy, and is dose-dependent. Administer pre-treatment and post-treatment antiemetics as clinically indicated [see Dosage and Administration (2.1)].
Monitor and manage patients with antiemetics, or fluid replacement, as clinically indicated. Consider withholding or delaying KYXATA if nausea or vomiting is severe or intolerable and is not responsive to antiemetics.
5.4 Peripheral Neuropathy
Peripheral neuropathy, including paresthesia, can occur in patients treated with KYXATA.
Peripheral neuropathy occurred in 4% of patients receiving carboplatin as a single agent (6% of pretreated patients with ovarian cancer). Peripheral neuropathy occurred in 10% of patients older than 65 who were previously treated with carboplatin.
Prolonged treatment, treatment with other platinum-containing therapies, or use in combination with other drugs that cause peripheral neuropathy may increase the incidence or severity of peripheral neuropathy.
Monitor for signs and symptoms of peripheral neuropathy. Withhold, reduce, or discontinue KYXATA depending on the severity and persistence of peripheral neuropathy as clinically indicated.
5.5 Embryo-Fetal Toxicity
Based on findings in animals and its mechanism of action, KYXATA can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. Administration of carboplatin to pregnant rats caused adverse developmental outcomes, including embryo-fetal lethality and structural abnormalities.
Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with KYXATA and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with KYXATA and for 3 months after the last dose [see Use in Specific Populations (8.1,8.3)].

6.1 Clinical 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 clinical practice.
Initial Treatment of Advanced Ovarian Cancer
The safety of KYXATA in combination with cyclophosphamide for initial treatment of advanced ovarian cancer was evaluated in two randomized controlled studies conducted by NCIC and SWOG [see Clinical Studies (14.1)]. Patients in the carboplatin arm received carboplatin in combination with cyclophosphamide and patients in the active-comparator arm received cisplatin in combination with cyclophosphamide.
Tables 3 and 4 summarize the adverse reactions and laboratory abnormalities in the NCIC study, respectively.

8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Based on findings from animals and its mechanism of action [see Clinical Pharmacology (12.1)], KYXATA can cause fetal harm when administered to a pregnant woman. Available data from case reports with carboplatin use in pregnant women are insufficient to inform a drug-associated risk. Administration of carboplatin to pregnant rats caused adverse developmental outcomes, including embryo-lethality and structural abnormalities (see Data). Advise pregnant women and females of reproductive potential of the potential risk to a fetus.
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
Carboplatin administered to pregnant rats was embryo-lethal and teratogenic.
8.2 Lactation
There are limited data on the presence of carboplatin or its metabolites in human milk, its effects on a breastfed child, or its effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with KYXATA and for 1 week after the last dose.
8.3 Females and Males of Reproductive Potential
KYXATA can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].
Pregnancy Testing
Verify pregnancy status in females of reproductive potential prior to initiating KYXATA.
Contraception
Females
Advise females of reproductive potential to use effective contraception during treatment with KYXATA and for 6 months after the last dose.
Males
Based on genotoxicity findings, advise male patients with female partners of reproductive potential to use effective contraception during treatment with KYXATA and for 3 months after the last dose [see Nonclinical Toxicology (13.1)].
8.4 Pediatric Use
The safety and effectiveness of KYXATA in pediatric patients have not been established.
Pediatric patients may be at risk of hearing loss if KYXATA is administered at higher than recommended dosages or in combination with other ototoxic agents.
8.5 Geriatric Use
Of the 395 patients treated with carboplatin in combination with cyclophosphamide, 141 (36%) were over 65 years of age, and 22 (6%) were 75 years and older [see Clinical Studies (14.1)].
No overall differences in effectiveness were observed between these patients and younger patients.
Elderly patients treated with carboplatin were more likely to develop severe thrombocytopenia or peripheral neuropathy than younger patients [see Warnings and Precautions (5.2, 5.4)]
Of the 1,942 patients with solid tumors or hematological malignancies from pooled clinical trials that received single-agent carboplatin, 414 (21%) were 65 years of age and older, and a similar incidence of other adverse reactions was seen in these older patients compared to patients less than 65 years of age.
Consider renal function when selecting the KYXATA dose for older adults since they often have decreased renal function. To minimize the risk of toxicity in older adults, calculate the dose based on AUC [see Dosage and Administration (2.3)].
8.6 Renal Impairment
For patients administered a dose based on AUC, no dose modification is recommended for renal impairment.
For patients administered a dose based on body surface area, reduce the dose if creatinine clearance (CLcr) is 16 to 59 mL/min [see Dosage and Administration (2.4)]. A recommended dose of KYXATA has not been established for patients with CLcr <16 mL/min.
Patients with impaired renal function are at increased risk of myelosuppression [see Warnings and Precautions (5.2)].
-
10 OVERDOSAGE
There is no known antidote for KYXATA overdosage. The anticipated complications of overdosage would be secondary to bone marrow suppression and/or hepatic toxicity. Patients receiving overdosages of carboplatin experienced severe liver function test abnormalities. Loss of vision, which can be complete for light and colors, has been reported after the use of carboplatin at doses higher than the recommended approved dosage for KYXATA. Vision recovers totally or to a significant extent after discontinuation of carboplatin. Clinically significant hearing loss has been reported to occur in pediatric patients when carboplatin was administered at higher than approved recommended doses for KYXATA and in combination with other ototoxic agents [see Drug Interactions (7)]. KYXATA is removed by dialysis.
Closely monitor patients suspected of receiving an overdose, including for the adverse reactions described above, and administer appropriate supportive treatment.
-
11 DESCRIPTION
KYXATA is a platinum-based drug. The chemical name for carboplatin is platinum, diammine [1,1- cyclobutane-dicarboxylato(2-)-0,0']-,(SP-4-2) and carboplatin has the following structural formula:
Carboplatin is a white crystalline powder with the molecular formula of C6H12N2O4Pt and a molecular weight of 371.26 g/mol. It is sparingly soluble in water and very slightly soluble in acetone and in alcohol. The pH of a 1% carboplatin solution in water is 5 to 7.
KYXATA (carboplatin) injection is supplied as a sterile, clear to pale yellow solution as 20 mg/2 mL, 80 mg/8mL, 500 mg/50 mL in multiple-dose vials for administration by intravenous infusion. Each mL contains 10 mg carboplatin.
-
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Carboplatin is a platinum-based drug that binds to DNA and forms DNA cross-links. These crosslinks inhibit DNA replication and transcription and trigger cytotoxic processes that lead to cell death.
12.2 Pharmacodynamics
Carboplatin exposure-response relationships and the time course of pharmacodynamic response have not been fully characterized.
12.3 Pharmacokinetics
Carboplatin pharmacokinetics were observed in patients with creatinine clearance (CLcr) of about 60 mL/min or greater following a dose of 300 mg/m2 to 500 mg/m2as an intravenous infusion over 30-minutes. The Cmax and AUC0-INF increase linearly with dose, although the increase was slightly more than dose proportional.
Distribution
The volume of distribution is 16 L.
Carboplatin is not bound to plasma proteins. No significant quantities of protein-free, ultrafilterable platinum-containing species other than carboplatin are present in plasma. However, platinum from carboplatin becomes irreversibly bound to plasma proteins.
Elimination
The elimination half-life is 2.6 to 5.9 hours and the total body clearance is 4.4 L/hour.
The elimination half-life of platinum from carboplatin bound to plasma proteins is a minimum of 5 days.
Excretion
The major route of elimination of carboplatin is renal excretion with 65% of the dose excreted in the urine within 12 hours and 71% within 24 hours. All of the platinum in the 24-hour urine is present as carboplatin.
Specific Populations
Renal Impairment: In patients with CLcr below 60 mL/min, the total body and renal clearances of carboplatin decrease as renal function decreases.

14.2 Use as a Single Agent for Secondary Treatment of Advanced Ovarian Cancer
In two prospective, randomized controlled studies in 47 patients with advanced ovarian cancer previously treated with chemotherapy who were treated with carboplatin as a single agent, 13% (6/47) of patients had clinical complete responses. The duration of these responses ranged from 45 to 71+ weeks. Within the group of patients previously treated with cisplatin, those who have developed progressive disease while receiving cisplatin therapy may have a decreased response rate.
