🩺 Clinical
Rolapitant is used along with other medications to prevent nausea and vomiting that may occur several days after receiving certain chemotherapy medications. Rolapitant is in a class of medications called antiemetics. It works by blocking the action of neurokinin and substance P, natural substances in the brain that cause nausea and vomiting.

⏳ Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

⛔ Contraindications ▾
4 CONTRAINDICATIONS VARUBI is contraindicated in patients taking CYP2D6 substrates with a narrow therapeutic index, such as thioridazine and pimozide. VARUBI can significantly increase the plasma concentrations of thioridazine and pimozide, which may result in QT prolongation and Torsades de Pointes [see Warnings and Precautions (5.1) ] . VARUBI is contraindicated in pediatric patients less than 2 years of age because of irreversible impairment of sexual development and fertility observed in juvenile rats at clinically relevant dosages [see Use in Specific Populations (8.4) ] .
CYP2D6 substrates with a narrow therapeutic index (e.g., thioridazine and pimozide) ( 4 , 5.1 , 7 ) Pediatric patients less than 2 years of age because of irreversible impairment of sexual development and fertility in juvenile rats ( 4 , 8.4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS CYP2D6 Substrates : Rolapitant is a moderate inhibitor of CYP2D6 and significantly increases the plasma concentrations of CYP2D6 substrates for at least 28 days following single dose administration of VARUBI. Before starting VARUBI, consider if patients require: thioridazine or pimozide; if so, use an alternative antiemetic to VARUBI or an alternative to thioridazine or pimozide that is not metabolized by CYP2D6. other CYP2D6 substrates; if so, consult the prescribing information for the CYP2D6 substrate for additional information about interactions with CYP2D6 inhibitors.
( 4 , 5.1 , 7 )
5.1Interaction with CYP2D6 Substrates Rolapitant is a moderate inhibitor of CYP2D6. Exposure to dextromethorphan, a CYP2D6 substrate, following a single dose of rolapitant increased about 3-fold on Days 8 and Day 22. The inhibition of CYP2D6 persisted on Day 28 with a 2.3-fold increase in dextromethorphan (CYP2D6 substrate) concentrations, the last time point measured.
The inhibitory effect of rolapitant on CYP2D6 is expected to persist beyond 28 days for an unknown duration following administration of VARUBI [see Drug Interactions (7) , Clinical Pharmacology (12.3) ] . Narrow Therapeutic Index Drugs (Thioridazine and Pimozide) VARUBI is contraindicated in patients taking CYP2D6 substrates with a narrow therapeutic index such as thioridazine and pimozide. Increased plasma concentrations of thioridazine and pimozide are associated with serious and/or life-threatening events of QT prolongation and Torsades de Pointes [see Contraindications (4) ] .
Before starting treatment with VARUBI, consider whether patients require treatment with thioridazine or pimozide. If patients require these drugs, use an alternative antiemetic to VARUBI or an alternative to thioridazine or pimozide that is not metabolized by CYP2D6. Other Drugs VARUBI can also increase plasma concentrations of other CYP2D6 substrates for at least 28 days following administration of VARUBI and may result in adverse reactions.
Before starting treatment with VARUBI, consult the prescribing information for CYP2D6 substrates to obtain additional information about interactions with CYP2D6 inhibitors.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Interaction with CYP2D6 Substrates [see Contraindications (4) , Warnings and Precautions (5.1) ] Most common adverse reactions (≥3%) are: Cisplatin Based Highly Emetogenic Chemotherapy: neutropenia, hiccups and abdominal pain. ( 6.1 ) Moderately Emetogenic Chemotherapy and Combinations of Anthracycline and Cyclophosphamide: decreased appetite, neutropenia, dizziness, dyspepsia, urinary tract infection, stomatitis and anemia.

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 to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. In 4 controlled clinical trials in patients receiving emetogenic cancer chemotherapy, VARUBI was given in combination with a 5-HT 3 receptor antagonist and dexamethasone. On Day 1 of Cycle 1 of chemotherapy, 1567 patients were treated with VARUBI and 1198 of these patients continued into the optional multiple cycle extension for up to 6 cycles of chemotherapy.
The median number of cycles administered 180 mg of VARUBI was four. VARUBI 180 mg was administered to 1294 patients. In Cycle 1 adverse reactions were reported in approximately 7% of patients treated with VARUBI compared with approximately 6% of patients treated with control therapy.
The most common adverse reactions reported with an incidence of ≥3% and greater than control are listed in Table 2 and Table 3 . Table 2: Most Common Adverse Reactions in Patients Receiving Cisplatin-Based Highly Emetogenic Chemotherapy (Cycle 1)* * all reactions occurring at ≥3% in the VARUBI group and for which the rate for VARUBI exceeds the rate for control VARUBI Regimen (VARUBI, Dexamethasone, and 5-HT 3 Receptor Antagonist) N = 624 Control (Placebo, Dexamethasone, and 5-HT 3 Receptor Antagonist) N = 627 Neutropenia 9% 8% Hiccups 5% 4% Abdominal Pain 3% 2% Table 3: Most Common Adverse Reactions in Patients Receiving Moderately Emetogenic Chemotherapy and Combinations of Anthracycline and Cyclophosphamide (Cycle 1)* *all reactions occurring at ≥3% in the VARUBI group and for which the rate for VARUBI exceeds the rate for control.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Rolapitant is a moderate CYP2D6 inhibitor. The inhibition of CYP2D6 persisted on Day 28 with a 2.3-fold increase in dextromethorphan concentrations, the last time point measured. The inhibitory effect of rolapitant on CYP2D6 is expected to persist beyond 28 days for an unknown duration following administration of VARUBI [see Clinical Pharmacology (12.3) ] .
Oral rolapitant is an inhibitor of Breast-Cancer-Resistance Protein (BCRP) and p-glycoprotein (P-gp). Rolapitant, given as a single oral dose, is not an inhibitor or inducer of CYP3A4 [see Clinical Pharmacology (12.3) ] . Therefore, no dosage adjustment for dexamethasone (CYP3A4 substrate) is needed when co-administered with VARUBI [see Dosage and Administration (2) ] .
Table 4 and Table 5 include drugs with clinically important drug interactions when administered concomitantly with VARUBI and instructions for preventing or managing them. Table 4: Clinically Relevant Interactions Affecting Drugs Co-Administered with VARUBI CYP2D6 Substrates Narrow Therapeutic Index Drugs (Thioridazine and Pimozide) Clinical Impact: Increased plasma concentrations of thioridazine and pimozide are associated with serious and/or life-threatening events of QT prolongation and Torsades de Pointes. Intervention: VARUBI is contraindicated in patients taking CYP2D6 substrates with a narrow therapeutic index such as thioridazine and pimozide.
If patients require these drugs, use an alternative antiemetic to VARUBI or an alternative to thioridazine or pimozide that is not metabolized by CYP2D6 [see Contraindications (4) , Warnings and Precautions (5.1) ]. Other CYP2D6 Substrates Clinical Impact: VARUBI can increase plasma concentrations of other CYP2D6 substrates for at least 28 days following administration of VARUBI and may result in adverse reactions. Before starting treatment with VARUBI consult the prescribing information of CYP2D6 substrates to obtain further information about interactions with CYP2D6 inhibitors [see Clinical Pharmacology (12.3) ].
Intervention: Before starting treatment with VARUBI consult the prescribing information of CYP2D6 substrates to obtain further information about interactions with CYP2D6 inhibitors [see Warnings and Precautions (5.1) ]. BCRP Substrates with a Narrow Therapeutic Index (e.g., methotrexate, topotecan, or irinotecan) Clinical Impact: Increased plasma concentrations of BCRP substrates (e.g., methotrexate, topotecan, or irinotecan) may result in potential adverse reactions [see Clinical Pharmacology (12.3) ]. Intervention: Monitor for adverse reactions related to the concomitant drug if use of VARUBI cannot be avoided.
Use the lowest effective dose of rosuvastatin (see prescribing information for additional information on recommended dosing). P-gp Substrates with a Narrow Therapeutic Index (e.g. digoxin) Clinical Impact: Increased plasma concentrations of P-gp substrates (e.g., digoxin) may result in potential adverse reactions [see Clinical Pharmacology (12.3) ]. Intervention: Monitor digoxin concentrations with concomitant use of VARUBI and adjust the dosage as needed to maintain therapeutic concentrations.
Monitor for adverse reactions if concomitant use of VARUBI with other P-gp substrates with a narrow therapeutic index cannot be avoided. Warfarin Clinical Impact: Although co-administration of intravenous rolapitant (VARBI is not approved for intravenous use), which has a higher C max than oral VARUBI, with warfarin did not substantially increase the systemic exposure to S-warfarin, the active enantiomer, the effects on INR and prothrombin time were not studied [see Clinical Pharmacology (12.3) ] . Intervention: Monitor INR and prothrombin time and adjust the dosage of warfarin, as needed with concomitant use of VARUBI, to maintain the target INR range.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary The limited data with VARUBI use in pregnant women are insufficient to inform a drug associated risk of adverse developmental outcomes. In animal reproduction studies, there were no adverse developmental effects observed with oral administration of rolapitant in rats and rabbits during the period of organogenesis at doses up to 1.2 times and 2.9-times, respectively, the maximum recommended human dose (MRHD) (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 The potential embryo-fetal toxicity of rolapitant was assessed in pregnant rats administered oral doses up to 22.5 mg/kg per day throughout the period of organogenesis.
Rats administered doses of 13.5 or 22.5 mg/kg per day rolapitant exhibited evidence of maternal toxicity including decreased body weight gain and/or body weight loss and a concomitant decrease in food consumption during the first week of dosing. No adverse embryo-fetal developmental effects were observed at doses up to 22.5 mg/kg per day rolapitant (approximately 1.2 times the recommended human dose on a body surface area basis). In rabbits administered rolapitant throughout the period of organogenesis, oral doses up to 27 mg/kg per day (approximately 2.9 times the recommended human dose on a body surface area basis) were without effects on the developing fetus.
The pre- and postnatal developmental effects of rolapitant were assessed in rats administered oral doses of 2.25, 9 or 22.5 mg/kg per day during the periods of organogenesis and lactation. Maternal toxicity was evident based on mortality/moribund condition, decreased body weight and food consumption, total litter loss, prolonged parturition, decreased length of gestation, and increased number of unaccounted for implantation sites at a dose of 22.5 mg/kg per day (approximately 1.2 times the recommended human dose on a body surface area basis).
Effects on offspring at this dose included decreased postnatal survival, and decreased body weights and body weight gain, and may be related to the maternal toxicity observed. At a maternal dose of 9 mg/kg per day rolapitant (approximately 0.5 times the recommended human dose on a body surface area basis), there was a decrease in memory in female pups in a maze test and a decrease in pup body weight.
8.2Lactation Risk Summary There are no data on the presence of rolapitant in human milk, the effects of rolapitant in the breastfed infant, or the effects of rolapitant on milk production. Rolapitant administered orally to lactating female rats was present in milk (see Data ) . The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for VARUBI and any potential adverse effects on the breastfed infant from VARUBI or from the underlying maternal condition or the use of concomitant chemotherapy.
Data Radioactivity from labeled [ 14 C] rolapitant was transferred into milk of lactating rats following a single oral dose of 22.5 mg/kg, and the maximum radioactivity in milk was observed at 12 hours post-dose. The mean milk/plasma radioactivity concentration ratios in dams at 1 to 48 hours post-dose ranged from 1.24 to 3.25. Based on average daily consumption of milk (2 mL/day) and the maximum milk radioactivity determined, pup exposure is expected to be 0.3% of the orally administered dose.

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of VARUBI have not been established in pediatric patients. VARUBI is contraindicated in pediatric patients less than 2 years of age [see Contraindications(4) ]. Rolapitant administration in juvenile rats (human age equivalent of birth to 2 years) resulted in abnormal ovarian and uterine development, early sexual development in females, delayed sexual development in males, and impaired fertility.
Juvenile Animal Toxicity Data A toxicity study in juvenile rats at rolapitant doses approximately 1.2 and 2.5 times the approved adult body surface area (BSA)-based dose from postnatal day (PND) 7 through PND 70 (approximate human age equivalent of birth to 16 years) identified reproductive toxicity. A subsequent toxicity study in juvenile rats was conducted to identify the critical window of exposure for reproductive toxicity. A rolapitant dose of 50 mg/kg/day (approximately 2.7 times the approved adult BSA-based dose) was administered daily from PNDs 7 through 70, 7 to 21, 21 to 42 and 42 to 70 (approximate human age equivalent of birth to 16 years, birth to 2 years, 2 years to 12 years, and 12 years to 16 years, respectively).
Female juvenile rats treated with rolapitant beginning on PND 7 developed adverse effects including partial or irreversible lower uterine weights that correlated with decreased endometrial glands of the uterus, decreases in the numbers of corpora lutea, implantation sites and live embryos and increases in pre- and post-implantation loss, and early resorptions. These adverse effects were observed in female juvenile rats administered rolapitant prior to PND 21 (approximate human age equivalent of 2 years). Additionally, juvenile rats treated with rolapitant beginning on either PND 7 or PND 21 developed slight changes in the onset of sexual maturation (including earlier attainment of vaginal opening in females and delay in preputial separation in males).

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Rolapitant is a selective and competitive antagonist of human substance P/NK1 receptors. Rolapitant does not have significant affinity for the NK2 or NK3 receptors or for a battery of other receptors, transporters, enzymes and ion channels. Rolapitant is also active in animal models of chemotherapy-induced emesis.
12.2Pharmacodynamics NK1 Receptor Occupancy A human Positron Emission Tomography (PET) study with rolapitant demonstrated that rolapitant crosses the blood brain barrier and occupies brain NK1 receptors. A dose-dependent increase in mean NK1 receptor occupancy was observed in the oral dose range from 4.5 mg to 180 mg of rolapitant. At the 180 mg oral dose of rolapitant, the mean NK1 receptor occupancy was 73% in the striatum at 120 hours after a single dose administration in healthy subjects.
The relationship between NK1 receptor occupancy and the clinical efficacy of rolapitant has not been established. Cardiac Electrophysiology At an oral dose of 720 mg (4 times the recommended oral dose), VARUBI does not prolong the QT interval to any clinically relevant extent.
12.3Pharmacokinetics Absorption Following a single oral dose administration of 180 mg VARUBI under fasting conditions to healthy subjects, rolapitant was measurable in plasma within 30 minutes and the peak plasma concentration (C max ) for rolapitant which was reached in about 4 hours and mean C max was 968 ng/mL (%CV:28%). Following multiple oral doses of 9 to 45 mg once daily of rolapitant (5% to 25% of the recommended dose) for 10 days, accumulation of rolapitant (ratio of AUC 0-24hr ) ranged from 5.0 to 5.3 fold.
The systemic exposures (C max and AUC) to rolapitant increased in a dose-proportional manner when single oral doses of rolapitant increased from 4.5 mg to 180 mg. With 4 times the recommended clinical oral dose of 180 mg, the C max and AUC of rolapitant increased 3.1 fold and 3.7 fold, respectively. Concomitant administration of a high-fat meal did not significantly affect the pharmacokinetics of rolapitant after administration of 180 mg VARUBI [see Dosage and Administration (2) ] .
Distribution Rolapitant was highly protein bound to human plasma (99.8%). The apparent volume of distribution (Vd/F) following a single oral dose of 180 mg rolapitant was 460 L in healthy subjects. The large Vd indicated an extensive tissue distribution of rolapitant.
In a population pharmacokinetic analysis of oral rolapitant, the Vd/F was 387 L in cancer patients. Elimination Following single oral doses (4.5 to 180 mg) of rolapitant, the mean terminal half-life (t 1/2 ) of rolapitant ranged from 169 to 183 hours (approximately 7 days), and was independent of dose. In a population pharmacokinetic analysis, the apparent total clearance (CL/F) of oral rolapitant was
0.96L/hour in cancer patients. Metabolism Rolapitant is metabolized primarily by CYP3A4 to form a major active metabolite, M19 (C4-pyrrolidine-hydroxylated rolapitant). In a mass balance study, the metabolite M19 was determined to be the major circulating metabolite.
The rate of formation of M19 was relatively slow, resulting in the delayed median T max of 120 hours (range: 24 to 168 hours) with C max of 183 ng/mL. The mean half-life of M19 was 158 hours. The exposure ratio of M19 to rolapitant was approximately 50% in plasma.
Excretion Rolapitant is eliminated primarily through the hepato/biliary route. Following administration of a single oral 180-mg dose of [ 14 C]-rolapitant, on average 14.2% (range 9% to 20%) and 73% (range 52% to 89%) of the dose was recovered in the urine and feces, respectively over 6 weeks. In pooled samples collected over 2 weeks, 8.3% of the dose was recovered in the urine primarily as metabolites and 37.8% of the dose was recovered in the feces primarily as unchanged rolapitant.
Unchanged rolapitant or M19 was not found in pooled urine sample. Specific Populations Age, Male and Female Patients and Racial or Ethnic Groups Po…
