1 INDICATIONS AND USAGE
Palonosetron hydrochloride injection is indicated in adults for prevention of:
- •
- acute and delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic cancer chemotherapy (MEC).
- •
- acute nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy (HEC).
- •
- postoperative nausea and vomiting (PONV) for up to 24 hours following surgery. Efficacy beyond 24 hours has not been demonstrated.
As with other antiemetics, routine prophylaxis is not recommended in patients in whom there is little expectation that nausea and/or vomiting will occur postoperatively. In patients where nausea and vomiting must be avoided during the postoperative period, palonosetron hydrochloride is recommended even where the incidence of postoperative nausea and/or vomiting is low.
Palonosetron hydrochloride injection is indicated in pediatric patients 1 month to less than 17 years of age for prevention of:
- •
- acute nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy, including highly emetogenic cancer chemotherapy.

3 DOSAGE FORMS AND STRENGTHS
4 CONTRAINDICATIONS
Palonosetron hydrochloride is contraindicated in patients known to have hypersensitivity to palonosetron [see Warnings and Precautions (5.1)].
5 WARNINGS AND PRECAUTIONS
5.1 Hypersensitivity Reactions
Hypersensitivity reactions, including anaphylaxis and anaphylactic shock, have been reported with administration of palonosetron hydrochloride injection [see Adverse Reactions (6.2)]. These reactions occurred in patients with or without known hypersensitivity to other 5-HT3 receptor antagonists. If hypersensitivity reactions occur, discontinue palonosetron hydrochloride injection and initiate appropriate medical treatment. Do not reinitiate palonosetron hydrochloride injection in patients who have previously experienced symptoms of hypersensitivity [see Contraindications (4)].
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 hydrochloride and other serotonergic drugs. If symptoms of serotonin syndrome occur, discontinue palonosetron hydrochloride and initiate supportive treatment. Patients should be informed of the increased risk of serotonin syndrome, especially if palonosetron hydrochloride is used concomitantly with other serotonergic drugs [see Drug Interactions (7.1)].
6 ADVERSE REACTIONS
Serious or otherwise clinically significant adverse reactions reported in other sections of labeling:
- •
- Hypersensitivity Reactions [see Warnings and Precautions (5.1)]
- •
- Serotonin Syndrome [see Warnings and Precautions (5.2)]
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 practice.
Chemotherapy-Induced Nausea and Vomiting
Adults
In double-blind randomized clinical trials for the prevention of nausea and vomiting induced by MEC or HEC, 1374 adult patients received a single dose of palonosetron hydrochloride injection, ondansetron (Studies 1 and 3) or dolasetron (Study 2) administered 30 minutes prior to chemotherapy [see Clinical Studies (14.1)]. Adverse reactions were similar in frequency and severity in all 3 treatment groups. Common adverse reactions reported in at least 2% of patients in these trials are shown in Table 2.

Pediatrics Aged 2 Months to 17 Years
In a pediatric clinical trial, 163 pediatric cancer patients with a mean age of 8 years received a single 20 mcg/kg (maximum 1.5 mg) intravenous infusion of palonosetron hydrochloride injection 30 minutes before beginning the first cycle of emetogenic chemotherapy [see Clinical Studies (14.2)]. Adverse reactions were evaluated in pediatric patients receiving palonosetron hydrochloride injection for up to 4 chemotherapy cycles. The following adverse reactions were reported in less than 1% of patients:
- •
- Nervous System: headache, dizziness, dyskinesia
- •
- General: infusion site pain
- •
- Dermatological: allergic dermatitis, skin disorder
Postoperative Nausea and Vomiting
The most common adverse reactions reported in at least 2% of adults receiving palonosetron hydrochloride injection 0.075 mg intravenously immediately before induction of anesthesia in 3 randomized placebo-controlled trials [see Clinical Studies (14.3)] are shown in Table 3. Rates of adverse reactions between palonosetron hydrochloride injection and placebo groups were similar. Some events are known to be associated with, or may be exacerbated by, concomitant perioperative and intraoperative medications administered in this surgical population. A thorough QT/QTc study demonstrated palonosetron hydrochloride injection does not prolong the QT interval to any clinically relevant extent [see Clinical Pharmacology (12.2)].

6.2 Postmarketing Experience
The following adverse reactions have been identified during postapproval use of palonosetron hydrochloride. 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.
- •
- Hypersensitivity reactions: including dyspnea, bronchospasm, swelling/edema, erythema, pruritus, rash, urticaria, anaphylaxis and anaphylactic shock [see Warnings and Precautions (5.1)]
- •
- Injection site reactions: including burning, induration, discomfort and pain
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 hydrochloride 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 hydrochloride 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 hydrochloride during the period of organogenesis at doses up to 1,894 and 3,789 times the recommended human intravenous dose in rats and rabbits, respectively (see Data).
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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 hydrochloride at doses up to 60 mg/kg/day (1,894 times the recommended human intravenous dose based on body surface area) or pregnant rabbits given oral doses up to 60 mg/kg/day (3,789 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 hydrochloride and any potential adverse effect on the breastfed infant from palonosetron or from the underlying maternal condition.
8.4 Pediatric Use
Chemotherapy-Induced Nausea and Vomiting
Safety and effectiveness of palonosetron hydrochloride injection have been established in pediatric patients aged 1 month to less than 17 years for the prevention of acute nausea and vomiting associated with initial and repeat courses of emetogenic cancer chemotherapy, including HEC. Use is supported by a clinical trial where 165 pediatric patients aged 2 months to less than 17 years were randomized to receive a single dose of palonosetron hydrochloride injection 20 mcg/kg (maximum 1.5 mg) administered as an intravenous infusion 30 minutes prior to the start of emetogenic chemotherapy [see Clinical Studies (14.2)]. While this study demonstrated that pediatric patients require a higher palonosetron dose than adults to prevent chemotherapy-induced nausea and vomiting, the safety profile is consistent with the established profile in adults [see Adverse Reactions (6.1)].
Safety and effectiveness of palonosetron hydrochloride in neonates (less than 1 month of age) have not been established.
Postoperative Nausea and Vomiting Studies
Safety and effectiveness have not been established in pediatric patients for prevention of postoperative nausea and vomiting. Two pediatric trials were performed.
Pediatric Study 1, a dose finding study was conducted to compare two doses of palonosetron, 1 mcg/kg (maximum 0.075 mg) versus 3 mcg/kg (maximum 0.25 mg). A total of 150 pediatric surgical patients participated, age range 1 month to less than 17 years. No dose response was observed.
Pediatric Study 2, a multicenter, double-blind, double-dummy, randomized, parallel group, active control, single-dose non-inferiority study, compared intravenous palonosetron hydrochloride (1 mcg/kg, maximum 0.075 mg) versus intravenous ondansetron. A total of 670 pediatric surgical patients participated, age 30 days to less than 17 years. The primary efficacy endpoint, Complete Response (CR: no vomiting, no retching, and no antiemetic rescue medication) during the first 24 hours postoperatively was achieved in 78.2% of patients in the palonosetron group and 82.7% in the ondansetron group. Given the pre-specified non-inferiority margin of -10%, the stratum adjusted Mantel-Haenszel statistical non-inferiority confidence interval for the difference in the primary endpoint, complete response (CR), was [-10.5, 1.7%], therefore non-inferiority was not demonstrated. Adverse reactions to palonosetron were similar to those reported in adults.
8.5 Geriatric Use
Of the 1374 adult cancer patients in clinical studies of intravenously administered palonosetron hydrochloride, 316 (23%) were 65 years and over, while 71 (5%) were at least 75 years and over. Of the 1520 adult patients in clinical studies of intravenously administered palonosetron hydrochloride, 73 (5%) were at least 65 years old [see Clinical Studies (14.1, 14.3)]. No overall differences in safety or effectiveness were observed between these subjects and 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 65 years of age and older compared to younger patients [see Clinical Pharmacology (12.3)]. No dose adjustment is required for geriatric patients.
10 OVERDOSAGE
There is no known antidote to palonosetron. 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 overdose. A single intravenous dose of palonosetron hydrochloride 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 hydrochloride, an antiemetic and antinauseant agent. It is a serotonin-3 (5-HT3) receptor antagonist with a strong binding affinity for this receptor. Chemically, palonosetron hydrochloride is: (3aS)-2-[(s)-1-azabicyclo[2.2.2]oct-3-yl]-2,3,3a,4,5,6-hexahydro-1-oxo-1H-benzo[de]isoquinoline hydrochloride. The molecular formula is C19H24N2O.HCl, with a molecular weight of 332.87. Palonosetron hydrochloride exists as a single isomer and has the following structural formula:
Palonosetron hydrochloride, USP 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 hydrochloride injection is a sterile, clear, colorless, non-pyrogenic, isotonic, buffered solution for intravenous administration. Palonosetron hydrochloride injection is available as a 5 mL single-dose vial.
Each 5 mL vial contains: 0.25 mg palonosetron (equivalent to 0.28 mg palonosetron hydrochloride), 207.5 mg mannitol, disodium edetate and citrate buffer in water for intravenous administration.
The pH of the solution in the 5 mL vial is 4.5 to 5.5. Hydrochloric acid or sodium hydroxide may have been added to adjust pH.
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.
Postoperative nausea and vomiting is influenced by multiple patient, surgical and anesthesia related factors and is triggered by release of 5-HT in a cascade of neuronal events involving both the central nervous system and the gastrointestinal tract. The 5-HT3 receptor has been demonstrated to selectively participate in the emetic response.
12.2 Pharmacodynamics
Cardiac Electrophysiology
The effect of intravenous palonosetron on blood pressure, heart rate, and ECG parameters including QTc were comparable to intravenous ondansetron and dolasetron in CINV clinical trials. In PONV clinical trials the effect of palonosetron on the QTc interval was no different from placebo. 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.
At a dose of 9 times the maximum recommended adult dose, palonosetron hydrochloride injection does not prolong the QT interval to any clinically relevant extent.
12.3 Pharmacokinetics
After intravenous dosing of palonosetron hydrochloride in healthy subjects and cancer patients, an initial decline in palonosetron 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 hydrochloride at 3 mcg/kg (or 0.21 mg/70 kg) to six cancer patients, mean (± SD) maximum plasma concentration was estimated to be 5630 ± 5480 ng/L and mean AUC was 35.8 ± 20.9 h•mcg/L.
Following intravenous administration of palonosetron hydrochloride injection 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 hydrochloride injection 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%.
After intravenous dosing of palonosetron hydrochloride injection in patients undergoing surgery (abdominal surgery or vaginal hysterectomy), the pharmacokinetic characteristics of palonosetron were similar to those observed in cancer patients.
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, 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. 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.
Specific Populations
Pediatric Patients
Pharmacokinetic data was obtained from a subset of pediatric cancer patients that received 10 mcg/kg or 20 mcg/kg as a single intravenous dose of palonosetron hydrochloride injection. When the dose was increased from 10 mcg/kg to 20 mcg/kg a dose-proportional increase in mean AUC was observed. Peak plasma concentrations (CT) reported at the end of the 15-minute infusion of 20 mcg/kg were highly variable in all age groups and tended to be lower in patients less than 6 years than in older patients as shown in Table 4. The median half-life was 30 hours in overall age groups and ranged from about 20 to 30 hours across age groups after administration of 20 mcg/kg.
The total body clearance (L/h/kg) in patients 12 to 17 years old was similar to that in healthy adults. There are no apparent differences in volume of distribution when expressed as L/kg.

Racial or Ethnic Groups
The pharmacokinetics of palonosetron were characterized in 24 healthy Japanese subjects over an intravenous dose range of 3 to 90 mcg/kg. Total body clearance was 25% higher in Japanese subjects compared to Whites, however, this increase is not considered to be clinically meaningful.
Patients with 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.
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 palonosetron appears to be low.
Dexamethasone
Coadministration of 0.25 mg palonosetron hydrochloride injection 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 hydrochloride injection 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).
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 hydrochloride 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 h•mcg/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 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 hydrochloride 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
14.1 Prevention of Nausea and Vomiting Associated with MEC and HEC in Adults
Efficacy of a single intravenous dose of palonosetron hydrochloride injection in preventing acute and delayed nausea and vomiting associated with MEC or HEC were studied in 4 trials. In these double-blind studies, 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 hydrochloride injection 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 dose of palonosetron hydrochloride injection with either a single dose of ondansetron (Study 1) or dolasetron (Study 2) given 30 minutes prior to MEC, 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 a single intravenous dose of palonosetron hydrochloride injection 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 HEC, 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 associated with HEC.
A double-blind trial involving 667 patients compared a single intravenous dose of palonosetron hydrochloride injection with a single intravenous dose of ondansetron (Study 3) given 30 minutes prior to HEC, 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
Studies 1, 2 and 3 show that palonosetron hydrochloride injection was effective in the prevention of nausea and vomiting associated with initial and repeat courses of MEC and HEC in the acute phase (0 to 24 hours) [Table 5]. Clinical superiority over other 5-HT3 receptor antagonists has not been adequately demonstrated in the acute phase. In Study 3, efficacy was greater when prophylactic corticosteroids were administered concomitantly.
Studies 1 and 2 show that palonosetron hydrochloride injection was effective in the prevention of nausea and vomiting associated with initial and repeat course of MEC in the delayed phase (24 to 120 hours) [Table 6] and overall phase (0 to 120 hours) [Table 7].

14.2 Prevention of Nausea and Vomiting Associated with Emetogenic Chemotherapy, Including HEC in Pediatric Patients
One double-blind, active-controlled clinical trial was conducted in pediatric cancer patients. The total population (N = 327) had a mean age of 8.3 years (range 2 months to 16.9 years) and were 53% male; and 96% white. Patients were randomized and received a 20 mcg/kg (maximum 1.5 mg) intravenous infusion of palonosetron hydrochloride injection 30 minutes prior to the start of emetogenic chemotherapy (followed by placebo infusions 4 and 8 hours after the dose of palonosetron hydrochloride injection) or 0.15 mg/kg of intravenous ondansetron 30 minutes prior to the start of emetogenic chemotherapy (followed by ondansetron 0.15 mg/kg infusions 4 and 8 hours after the first dose of ondansetron, with a maximum total dose of 32 mg). Emetogenic chemotherapies administered included doxorubicin, cyclophosphamide (< 1500 mg/m2), ifosfamide, cisplatin, dactinomycin, carboplatin, and daunorubicin. Adjuvant corticosteroids, including dexamethasone, were administered with chemotherapy in 55% of patients.
Complete Response in the acute phase of the first cycle of chemotherapy was defined as no vomiting, no retching, and no rescue medication in the first 24 hours after starting chemotherapy. Efficacy was based on demonstrating non-inferiority of intravenous palonosetron hydrochloride injection compared to intravenous ondansetron. Non-inferiority criteria were met if the lower bound of the 97.5% confidence interval for the difference in Complete Response rates of intravenous palonosetron hydrochloride injection minus intravenous ondansetron was larger than -15%. The non-inferiority margin was 15%.
Efficacy Results
As shown in Table 8, intravenous palonosetron hydrochloride 20 mcg/kg (maximum 1.5 mg) demonstrated non-inferiority to the active comparator during the 0 to 24-hour time interval.

14.3 Prevention of Postoperative Nausea and Vomiting in Adults
In a multicenter, randomized, stratified, double-blind, parallel-group, clinical trial, palonosetron hydrochloride injection was compared to placebo for PONV in 546 patients undergoing abdominal and gynecological surgery. All patients received general anesthesia. The trial was conducted predominantly in the U.S. in the out-patient setting for patients undergoing elective gynecologic or abdominal laparoscopic surgery and stratified at randomization for the following risk factors: gender, non-smoking status, history of PONV and/or motion sickness.
Patients were randomized to receive a single dose of palonosetron hydrochloride injection 0.025 mg, 0.050 mg or 0.075 mg or placebo, each given intravenously immediately prior to induction of anesthesia. Antiemetic activity of palonosetron hydrochloride injection was evaluated during the 0 to 72-hour time period after surgery.
Of the 138 patients treated with palonosetron hydrochloride injection 0.075 mg and evaluated for efficacy, 96% were women; 66% had a history of PONV or motion sickness; 85% were non-smokers. As for race, 63% were White, 20% were Black, 15% were Hispanic, and 1% were Asian. The age of patients ranged from 21 to 74 years, with a mean age of 38 years. Three patients were greater than 65 years of age.
Co-primary efficacy measures were Complete Response (CR) defined as no emetic episode and no use of rescue medication in 0 to 24 hours and 24 to 72 hours postoperatively.
Secondary efficacy endpoints included:
- •
- Complete Response (CR) 0 to 48 hours and 0 to 72 hours
- •
- Complete Control (CC) defined as CR and no more than mild nausea
- •
- Severity of nausea (none, mild, moderate, severe)
The primary hypothesis was that at least one of the three palonosetron doses were superior to placebo.
Complete Response Rates for palonosetron hydrochloride injection 0.075 mg and placebo in this trial are described in Table 9.

Palonosetron hydrochloride injection as a single dose of 0.075 mg reduced the severity of nausea compared to placebo. Analyses of other secondary endpoints indicate that palonosetron hydrochloride injection 0.075 mg was numerically better than placebo, however, statistical significance was not formally demonstrated.
A randomized, double-blind, multicenter, placebo-controlled, dose ranging study was performed to evaluate palonosetron hydrochloride injection for PONV following abdominal or vaginal hysterectomy. Five intravenous doses (0.1, 0.3, 1.0, 3.0 and 30 mcg/kg) were evaluated in a total of 381 intent-to-treat patients. The primary efficacy measure was the proportion of patients with CR in the first 24 hours after recovery from surgery. The lowest effective dose was palonosetron hydrochloride injection 1 mcg/kg (approximately 0.075 mg) which had a CR rate of 44% versus 19% for placebo, p = 0.004 and significantly reduced the severity of nausea versus placebo, p = 0.009.
