         Moderately emetogenic cancer chemotherapy – prevention of acute and delayed nausea and vomiting associated with initial and repeat courses

         Highly emetogenic cancer chemotherapy – prevention of acute nausea and vomiting associated with initial and repeat courses

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Recommended Dosage

    Chemotherapy-Induced Nausea and Vomiting

    The recommended adult dosage of Palonosetron HCl Injection is 0.25 mg administered as a single intravenous dose over 30 seconds.  Dosing should occur approximately 30 minutes before the start of chemotherapy.

    2.2 Instructions for Intravenous Administration

    • Palonosetron HCl Injection is intended for direct intravenous administration without further dilution.
    • Do not mix with other drugs.
    • When applicable, flush the line with normal saline before and after administration of Palonosetron HCl Injection to ensure complete dosing and to avoid drug incompatibilities.
    • Inspect Palonosetron HCl Injection visually for particulate matter and discoloration before administration.
  • 3 DOSAGE FORMS AND STRENGTHS

    Palonosetron Hydrochloride Injection is sterile, clear, and colorless:

       0.25 mg palonosetron in 2 mL (0.125 mg/mL) in a single-dose vial

  • 4 CONTRAINDICATIONS

    Palonosetron HCl Injection is contraindicated in patients known to have hypersensitivity to the drug or any of its components [see Adverse Reactions (6.2)].

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Hypersensitivity

    Hypersensitivity reactions, including anaphylaxis, have been reported with or without known hypersensitivity to other 5-HT3 receptor antagonists.

    5.2 Serotonin Syndrome

    The development of serotonin syndrome has been reported with 5-HT3 receptor antagonists. Most reports have been associated with concomitant use of serotonergic drugs (e.g., selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors, mirtazapine, fentanyl, lithium, tramadol, and intravenous methylene blue).  Some of the reported cases were fatal. Serotonin syndrome occurring with overdose of another 5-HT3 receptor antagonist alone has also been reported. The majority of reports of serotonin syndrome related to 5-HT3 receptor antagonist use occurred in a post-anesthesia care unit or an infusion center.

    Symptoms associated with serotonin syndrome may include the following combination of signs and symptoms: mental status changes (e.g. agitation, hallucinations, delirium, and coma), autonomic instability (e.g. tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, with or without gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).  Patients should be monitored for the emergence of serotonin syndrome, especially with concomitant use of Palonosetron HCl Injection and other serotonergic drugs.  If symptoms of serotonin syndrome occur, discontinue Palonosetron HCl Injection and initiate supportive treatment.  Patients should be informed of the increased risk of serotonin syndrome, especially if Palonosetron HCl Injection is used concomitantly with other serotonergic drugs [see Drug Interactions (7.1)].

  • 6 ADVERSE REACTIONS

    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 reported in practice.

    The safety of Palonosetron HCl Injection has been established from adequate and well-controlled studies of another intravenous formulation of palonosetron HCl [see Clinical Studies (14)]. Below is a display of the adverse reactions of palonosetron HCl in these adequate and well-controlled studies.

    Chemotherapy-Induced Nausea and Vomiting

    In clinical trials for the prevention of nausea and vomiting induced by moderately or highly emetogenic chemotherapy, 1374 adult patients received a single 0.25 mg dose of palonosetron HCl. Adverse reactions were similar in frequency and severity with intravenous palonosetron HCl and ondansetron or dolasetron.

    The following is a listing of all adverse reactions reported by ≥ 2% of patients in these trials (Table 1).

    Vascular: < 1%: vein discoloration, vein distention.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during post approval use of another intravenous formulation of palonosetron HCl. 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.

    Very rare cases (<1/10,000) of hypersensitivity reactions including anaphylaxis and anaphylactic shock and injection site reactions (burning, induration, discomfort and pain) were reported from postmarketing experience of palonosetron HCl 0.25 mg in the prevention of chemotherapy-induced nausea and vomiting.

  • 7 DRUG INTERACTIONS

    7.1 Serotonergic Drugs

    Serotonin syndrome (including altered mental status, autonomic instability, and neuromuscular symptoms) has been described following the concomitant use of 5-HT3 receptor antagonists and other serotonergic drugs, including selective serotonin reuptake inhibitors (SSRIs) and serotonin and noradrenaline reuptake inhibitors (SNRIs).  Monitor for the emergence of serotonin syndrome.  If symptoms occur, discontinue Palonosetron HCl Injection and initiate supportive treatment [see Warnings and Precautions (5.2)].

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    There are no available data on palonosetron HCl use in pregnant women to inform a drug-associated risk. In animal reproduction studies, no effects on embryo-fetal development were observed with the administration of oral palonosetron HCl to rats and rabbits during organogenesis at doses up to 1894 and 3789 times the recommended human intravenous dose, respectively [see Data].

    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

    In animal reproduction studies, no effects on embryo-fetal development were observed in pregnant rats given oral palonosetron HCl at doses up to 60 mg/kg/day (1894 times the recommended human intravenous dose based on body surface area) or pregnant rabbits given oral doses up to 60 mg/kg/day (3789 times the recommended human intravenous dose based on body surface area) during the period of organogenesis.

    8.2 Lactation

    Risk Summary

    There are no data on the presence of palonosetron in human milk, the effects of palonosetron on the breastfed infant, or the effects of palonosetron on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Palonosetron HCl Injection and any potential adverse effects on the breastfed infant from palonosetron or from the underlying maternal condition.

    8.4 Pediatric Use

    This product has not been approved for use in pediatric patients for prevention of chemotherapy-induced nausea and vomiting.

    8.5 Geriatric Use

    Of the 1374 adult cancer patients in clinical studies of intravenously administered palonosetron HCl for CINV, 316 (23%) were aged 65 years and over, while 71 (5%) were aged 75 years and over.  No overall differences in safety or effectiveness were observed between these subjects and the younger subjects, but greater sensitivity in some older individuals cannot be ruled out. Population pharmacokinetics analysis did not reveal any differences in palonosetron pharmacokinetics between cancer patients aged 65 years and older and younger patients (18 to 64 years).  No dose adjustment or special monitoring are required for geriatric patients.

  • 10 OVERDOSAGE

    There is no known antidote to palonosetron HCl. Overdose should be managed with supportive care.

    Dialysis studies have not been performed; however, due to the large volume of distribution, dialysis is unlikely to be an effective treatment for palonosetron HCl overdose. A single intravenous dose of palonosetron HCl at 30 mg/kg (947 and 474 times the human dose for rats and mice, respectively, based on body surface area) was lethal to rats and mice. The major signs of toxicity were convulsions, gasping, pallor, cyanosis and collapse.

  • 11 DESCRIPTION

    Palonosetron Hydrochloride Injection contains palonosetron as palonosetron HCl, an antiemetic and antinauseant agent. It is a serotonin-3 (5-HT3) receptor antagonist with a strong binding affinity for this receptor. Chemically, palonosetron HCl is: (3aS)-2-[(S)-1-Azabicyclo [2.2.2]oct-3-yl]-2,3,3a,4,5,6­ hexahydro-1-oxo-1Hbenz[de]isoquinoline hydrochloride. The empirical formula is C19H24N2OHCl, with a molecular weight of 332.87. Palonosetron HCl exists as a single isomer and has the following structural formula:

    structure

    Palonosetron HCl is a white to off-white crystalline powder. It is freely soluble in water, soluble in propylene glycol, and slightly soluble in ethanol and 2-propanol.

    Palonosetron HCl Injection is a sterile, clear, colorless, non-pyrogenic, non-buffered, hypotonic solution for intravenous administration.  Palonosetron HCl Injection contains no preservative or chelating agent. Palonosetron HCl Injection is available as 2 mL single-dose vial.

    Each 2 mL vial contains 0.25 mg palonosetron base equivalent to 0.28 mg palonosetron HCl, and water for intravenous administration.

    The pH of the solution in the 2 mL vial is 6.5 to 8.5.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Palonosetron is a 5-HT3 receptor antagonist with a strong binding affinity for this receptor and little or no affinity for other receptors.

    Cancer chemotherapy may be associated with a high incidence of nausea and vomiting, particularly when certain agents, such as cisplatin, are used. 5-HT3 receptors are located on the nerve terminals of the vagus in the periphery and centrally in the chemoreceptor trigger zone of the area postrema. It is thought that chemotherapeutic agents produce nausea and vomiting by releasing serotonin from the enterochromaffin cells of the small intestine and that the released serotonin then activates 5-HT3 receptors located on vagal afferents to initiate the vomiting reflex.

    12.2 Pharmacodynamics

    Cardiac Electrophysiology

    The effect of intravenous palonosetron HCl on blood pressure, heart rate, and ECG parameters including QTc were comparable to intravenous ondansetron and dolasetron in CINV clinical trials. In non-clinical studies palonosetron possesses the ability to block ion channels involved in ventricular de- and re-polarization and to prolong action potential duration.

    The effect of palonosetron on QTc interval was evaluated in a double blind, randomized, parallel, placebo and positive (moxifloxacin) controlled trial in adult men and women. The objective was to evaluate the ECG effects of intravenously administered palonosetron HCl at single doses of 0.25, 0.75 or 2.25 mg in 221 healthy subjects. At a dose 9 times the maximum recommended dose, palonosetron did not prolong the QT interval to any clinically relevant extent.

    12.3 Pharmacokinetics

    After intravenous dosing of palonosetron HCl in healthy subjects and cancer patients, an initial decline in plasma concentrations is followed by a slow elimination from the body.  Mean maximum plasma concentration (Cmax) and area under the concentration-time curve (AUC0-∞) are generally dose-proportional over the dose range of 0.3 to 90 mcg/kg in healthy subjects and in cancer patients. Following a single intravenous dose of palonosetron HCl at 3 mcg/kg (or 0.21 mg/70 kg) to six cancer patients, the mean (±SD) maximum plasma concentration was estimated to be 5630 ± 5480 ng/L and the mean AUC was 35.8 ± 20.9 hmcg/L.

    Following intravenous administration of palonosetron HCl 0.25 mg once every other day for 3 doses in 11 cancer patients, the mean increase in plasma palonosetron concentration from Day 1 to Day 5 was 42 ± 34%. Following intravenous administration of palonosetron HCl 0.25 mg once daily for 3 days in 12 healthy subjects, the mean (±SD) increase in plasma palonosetron concentration from Day 1 to Day 3 was 110 ± 45%.

    Distribution
    Palonosetron has a volume of distribution of approximately 8.3 ± 2.5 L/kg. Approximately 62% of palonosetron is bound to plasma proteins.

    Elimination
    After a single intravenous dose of 10 mcg/kg [14C]-palonosetron HCl, approximately 80% of the dose was recovered within 144 hours in the urine with palonosetron representing approximately 40% of the administered dose. In healthy subjects, the total body clearance of palonosetron was 0.160 ± 0.035 L/h/kg and renal clearance was 0.067 ± 0.018 L/h/kg. The mean terminal elimination half-life is approximately 40 hours.

    Metabolism
    Palonosetron is eliminated by multiple routes with approximately 50% metabolized to form two primary metabolites: N-oxide-palonosetron and 6-S-hydroxy-palonosetron. These metabolites each have less than 1% of the 5-HT3 receptor antagonist activity of palonosetron. In vitro metabolism studies have suggested that CYP2D6 and to a lesser extent, CYP3A4 and CYP1A2 are involved in the metabolism of palonosetron. However, clinical pharmacokinetic parameters are not significantly different between poor and extensive metabolizers of CYP2D6 substrates.

    Excretion
    Palonosetron is partially eliminated from the body through renal excretion.

    Specific Populations
    Renal Impairment
    Mild to moderate renal impairment does not significantly affect palonosetron pharmacokinetic parameters. Total systemic exposure increased by approximately 28% in patients with severe renal impairment relative to healthy subjects. This increase is not considered clinically meaningful.

    Hepatic Impairment
    Hepatic impairment does not significantly affect total body clearance of palonosetron compared to the healthy subjects.

    Race/Ethnicity
    The pharmacokinetics of palonosetron were characterized in twenty-four healthy Japanese subjects over the dose range of 3 to 90 mcg/kg.  Total body clearance was 25% higher in Japanese subjects compared to Whites; however, no dose adjustment is required.  The pharmacokinetics of palonosetron in Blacks has not been adequately characterized.

    Drug Interaction Studies
    In vitro studies indicated that palonosetron is not an inhibitor of CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2D6, CYP2E1 and CYP3A4/5 (CYP2C19 was not investigated) nor does it induce the activity of CYP1A2, CYP2D6, or CYP3A4/5. Therefore, the potential for clinically significant drug interactions with palonsetron appears to be low.

    Dexamethasone
    Coadministration of 0.25 mg palonosetron HCl and 20 mg dexamethasone administered intravenously in healthy subjects revealed no pharmacokinetic drug-interactions between palonosetron and dexamethasone.

    Oral Aprepitant
    In an interaction study in healthy subjects where a single 0.25 mg intravenous dose of palonosetron HCl was administered on day 1 and oral aprepitant for 3 days (125 mg/80 mg/80 mg), the pharmacokinetics of palonosetron were not significantly altered (AUC: no change, Cmax: 15% increase).

    Metoclopramide
    A study in healthy subjects involving a single 0.75 mg intravenous dose of palonosetron HCl and steady state oral metoclopramide (10 mg four times daily) demonstrated no significant pharmacokinetic interaction.

    Corticosteroids, Analgesics, Antiemetics/Antinauseants, Antispasmodics and Anticholinergic Agents
    In controlled clinical trials, palonosetron HCl has been safely administered with corticosteroids, analgesics, antiemetics/antinauseants, antispasmodics and anticholinergic agents.

  • 13 NONCLINICAL TOXICOLOGY

    13.1   Carcinogenesis, Mutagenesis, Impairment of Fertility

    In a 104-week carcinogenicity study in CD-1 mice, animals were treated with oral doses of palonosetron HCl at 10, 30 and 60 mg/kg/day. Treatment with palonosetron was not tumorigenic. The highest tested dose produced a systemic exposure to palonosetron (plasma AUC) of about 150 to 289 times the human exposure (AUC = 29.8 hmcg/L) at the recommended intravenous dose of 0.25 mg. In a 104-week carcinogenicity study in Sprague-Dawley rats, male and female rats were treated with oral doses of 15, 30 and 60 mg/kg/day and 15, 45 and 90 mg/kg/day, respectively. The highest doses produced a systemic exposure to palonosetron (plasma AUC) of 137 and 308 times the human exposure at the recommended dose. Treatment with palonosetron HCl produced increased incidences of adrenal benign pheochromocytoma and combined benign and malignant pheochromocytoma, increased incidences of pancreatic Islet cell adenoma and combined adenoma and carcinoma and pituitary adenoma in male rats. In female rats, it produced hepatocellular adenoma and carcinoma and increased the incidences of thyroid C-cell adenoma and combined adenoma and carcinoma.

    Palonosetron was not genotoxic in the Ames test, the Chinese hamster ovarian cell (CHO/HGPRT) forward mutation test, the ex vivo hepatocyte unscheduled DNA synthesis (UDS) test or the mouse micronucleus test. It was, however, positive for clastogenic effects in the Chinese hamster ovarian (CHO) cell chromosomal aberration test.

    Palonosetron HCl at oral doses up to 60 mg/kg/day (about 1894 times the recommended human intravenous dose based on body surface area) was found to have no effect on fertility and reproductive performance of male and female rats.

  • 14 CLINICAL STUDIES

    The safety and efficacy of Palonosetron HCl Injection have been established based on adequate and well-controlled adult studies of another intravenous formulation of palonosetron HCl in chemotherapy induced nausea and vomiting. Below is a display of the results of these adequate and well-controlled studies of palonosetron HCl.

    14.1 Chemotherapy-Induced Nausea and Vomiting

    Efficacy of a single intravenous dose of palonosetron HCl in preventing acute and delayed nausea and vomiting induced by both moderately and highly emetogenic chemotherapy was studied in 4 trials. In these double-blind trials, complete response rates (no emetic episodes and no rescue medication) and other efficacy parameters were assessed through at least 120 hours after administration of chemotherapy. The safety and efficacy of palonosetron HCl in repeated courses of chemotherapy was also assessed.

    Moderately Emetogenic Chemotherapy:

    Two double-blind trials (Study 1 and Study 2) involving 1132 patients compared a single intravenous dose of palonosetron HCl with either a single intravenous dose of ondansetron (Study 1) or dolasetron (Study 2) given 30 minutes prior to moderately emetogenic chemotherapy including carboplatin, cisplatin ≤ 50 mg/m², cyclophosphamide < 1500 mg/m², doxorubicin > 25 mg/m², epirubicin, irinotecan, and methotrexate > 250 mg/m². Concomitant corticosteroids were not administered prophylactically in Study 1 and were only used by 4 to 6% of patients in Study 2. The majority of patients in these studies were women (77%), White (65%) and naïve to previous chemotherapy (54%). The mean age was 55 years.

    Highly Emetogenic Chemotherapy:

    A double-blind, dose-ranging trial evaluated the efficacy of single-dose intravenous palonosetron from 0.3 to 90 mcg/kg (equivalent to < 0.1 mg to 6 mg fixed dose) in 161 chemotherapy-naïve adult cancer patients receiving highly emetogenic chemotherapy (either cisplatin ≥ 70 mg/m² or cyclophosphamide >1100 mg/m²). Concomitant corticosteroids were not administered prophylactically. Analysis of data from this trial indicates that 0.25 mg is the lowest effective dose in preventing acute nausea and vomiting induced by highly emetogenic chemotherapy.

    A double-blind trial involving 667 patients compared a single intravenous dose of palonosetron HCl with a single intravenous dose of ondansetron (Study 3) given 30 minutes prior to highly emetogenic chemotherapy including cisplatin ≥ 60 mg/m², cyclophosphamide > 1500 mg/m², and dacarbazine. Corticosteroids were co-administered prophylactically before chemotherapy in 67% of patients. Of the 667 patients, 51% were women, 60% White, and 59% naïve to previous chemotherapy. The mean age was 52 years.

    Efficacy Results:

    The antiemetic activity of palonosetron HCl was evaluated during the acute phase (0-24 hours) [Table 3], delayed phase (24-120 hours) [Table 4], and overall phase (0-120 hours) [Table 5] post-chemotherapy in Studies 1, 2 and 3.

    These trials show that palonosetron HCl was effective in the prevention of acute nausea and vomiting associated with initial and repeat courses of moderately and highly emetogenic cancer chemotherapy.

    In Study 3, efficacy was greater when prophylactic corticosteroids were administered concomitantly. Clinical superiority over other 5-HT3 receptor antagonists has not been adequately demonstrated in the acute phase.
