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.

LIVTENCITY is a cytomegalovirus (CMV) pUL97 kinase inhibitor indicated for the treatment of adults and pediatric patients (12 years of age and older and weighing at least 35 kg) with post-transplant CMV infection/disease that is refractory to treatment (with or without genotypic resistance) with ganciclovir, valganciclovir, cidofovir or foscarnet.
( 1 , 8.4 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION 400 mg (two 200 mg tablets) orally twice daily with or without food. ( 2.1 , 8.4 )
2.1Recommended Dosage The recommended dosage in adults and pediatric patients (12 years of age and older and weighing at least 35 kg) is 400 mg (two 200 mg tablets) taken orally twice daily with or without food [see Use in Specific Populations (8.4) , Clinical Pharmacology (12.3) and Clinical Studies (14) ] .
2.2Dosage Adjustment When Coadministered with Anticonvulsants If LIVTENCITY is coadministered with carbamazepine, increase the dosage of LIVTENCITY to 800 mg (four 200 mg tablets) twice daily [see Drug Interactions (7.3) and Clinical Pharmacology (12.3) ] . If LIVTENCITY is coadministered with phenytoin or phenobarbital, increase the dosage of LIVTENCITY to 1,200 mg (six 200 mg tablets) twice daily [see Drug Interactions (7.3) and Clinical Pharmacology (12.3) ] .
2.3Dosage Adjustment When Coadministered with Rifabutin If LIVTENCITY is co-administered with rifabutin, increase the dosage of LIVTENCITY to 800 mg (four 200 mg tablets) twice daily [see Drug Interactions (7.3) and Clinical Pharmacology (12.3) ] .
2.4Administration Instructions The immediate-release tablets can be taken as whole, dispersed or crushed tablets by mouth, or as dispersed tablets through a nasogastric or orogastric tube (French size 10 or larger). The suspension may be prepared ahead of time and stored at room temperature for up to 8 hours. Administration of Dispersed Tablets or Crushed Tablets by Mouth Place the appropriate number of tablets for the prescribed dose into a suitable container.
If desired, the tablets may be crushed. Add the appropriate volume of drinking water (other liquids have not been tested) to make a suspension (see Table 1 below) . Table 1: Number of Tablets and Volume of Drinking Water Needed to Make a Suspension for Administration of Dispersed or Crushed Tablets by Mouth Recommended Dosage Number of 200 mg Tablets Volume of Drinking Water 400 mg Two 30 mL 800 mg Four 60 mL 1,200 mg Six 90 mL Swirl the container gently to keep the particles from settling, and administer the suspension before it settles.
The mixture will have a bitter taste. Rinse the container with 15 mL of drinking water and administer the rinse water. Repeat Step 3.
Visually confirm that no particles are left in the container. If particles remain, repeat Step 3. Administration of Dispersed Tablets through a Nasogastric (NG) or Orogastric (OG) Tube Remove the cap (if applicable) and plunger out of a 50 or 60 mL catheter-tip compatible syringe or equivalent.
Add two tablets into the syringe body and place the plunger back in the syringe. Only two tablets can be administered via NG or OG tube at a time. Draw 30 mL of drinking water (other liquids have not been tested) into the syringe and hold the syringe with the tip pointing upward.
Pull the plunger further to a higher volume position to have some air space in the syringe. Place the cap back on the syringe (if applicable). Shake the syringe well (careful not to spill the contents) for about 30 to 45 seconds or until the tablets are completely dispersed.
Once the tablets are completely dispersed in the syringe, remove the cap from the syringe again (if applicable) and attach the syringe to the NG or OG tube and administer the dispersion before it settles. Draw 15 mL of water using the same syringe and flush through the same NG or OG tube. Repeat Step 4 and make sure no particles are left in the syringe by visual inspection.
If particles remain, repeat Step 4. For doses of 800 mg (four 200 mg tablets) and 1,200 mg (six 200 mg tablets) [see Dosage and Administration (2.2 , 2.3) ] , repeat Steps 1-5 until prescribed dose is reached. The same syringe, NG or OG tube can be used.
💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS Tablet: 200 mg, blue, oval shaped convex tablet debossed with "SHP" on one side and "620" on the other side. Tablets: 200 mg of maribavir. ( 3 )
⛔ Contraindications ▾
4 CONTRAINDICATIONS None. None. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS LIVTENCITY may antagonize the antiviral activity of ganciclovir and valganciclovir. Coadministration is not recommended. ( 5.1 , 7.1 ) Virologic failure can occur during and after treatment with LIVTENCITY.
Monitor CMV DNA levels and check for resistance if patient does not respond to treatment. Some maribavir pUL97 resistance-associated substitutions confer cross-resistance to ganciclovir and valganciclovir. ( 5.2 , 12.4 , 14.1 ) The concomitant use of LIVTENCITY and certain drugs may result in potentially significant drug interactions, some of which may lead to reduced therapeutic effect of LIVTENCITY or adverse reactions of concomitant drugs.
( 5.1 , 5.3 , 7.1 , 7.2 , 7.3 ) LIVTENCITY has the potential to increase the drug concentrations of certain immunosuppressant drugs where minimal concentration changes may lead to serious adverse events (including tacrolimus, cyclosporine, sirolimus and everolimus). Frequently monitor immunosuppressant drug levels throughout treatment with LIVTENCITY, especially following initiation and after discontinuation of LIVTENCITY and adjust the dose, as needed. ( 5.3 )
5.1Risk of Reduced Antiviral Activity When Coadministered with Ganciclovir and Valganciclovir LIVTENCITY may antagonize the antiviral activity of ganciclovir and valganciclovir by inhibiting human CMV pUL97 kinase, which is required for activation/phosphorylation of ganciclovir and valganciclovir. Coadministration of LIVTENCITY with ganciclovir or valganciclovir is not recommended [see Drug Interactions (7.1) and Microbiology (12.4) ] .
5.2Virologic Failure During Treatment and Relapse Post-Treatment Virologic failure due to resistance can occur during and after treatment with LIVTENCITY. Virologic relapse during the post-treatment period usually occurred within 4-8 weeks after treatment discontinuation. Some maribavir pUL97 resistance-associated substitutions confer cross-resistance to ganciclovir and valganciclovir.
Monitor CMV DNA levels and check for maribavir resistance if the patient is not responding to treatment or relapses [see Microbiology (12.4) and Clinical Studies (14.1) ] .
5.3Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions The concomitant use of LIVTENCITY and certain drugs may result in potentially significant drug interactions, some of which may lead to reduced therapeutic effect of LIVTENCITY or adverse reactions of concomitant drugs [see Drug Interactions (7) ] . See Table 4 for steps to prevent or manage these possible or known significant drug interactions, including dosing recommendations. Consider the potential for drug interactions prior to and during LIVTENCITY therapy; review concomitant medications during LIVTENCITY therapy and monitor for adverse reactions.
Maribavir is primarily metabolized by CYP3A4. Drugs that are strong inducers of CYP3A4 are expected to decrease maribavir plasma concentrations and may result in reduced virologic response. Thus, coadministration of LIVTENCITY with these drugs is not recommended, except with a dose adjustment when coadministered with selected anticonvulsants (carbamazepine and phenytoin).
With moderate CYP3A4 inducers rifabutin (antimycobacterial) and phenobarbital (anticonvulsant), a dose adjustment is recommended [see Dosage and Administration (2.2 , 2.3) and Drug Interactions (7.3) ] . For other moderate CYP3A4 inducers, the appropriate maribavir dose adjustment has not been determined. Use with Immunosuppressant Drugs LIVTENCITY has the potential to increase the drug concentrations of certain immunosuppressant drugs where minimal concentration changes may lead to serious adverse events (including tacrolimus, cyclosporine, sirolimus and everolimus).
Frequently monitor immunosuppressant drug levels throughout treatment with LIVTENCITY, especially following initiation and after discontinuation of LIVTENCITY and adjust the immunosuppressant dose, as needed [see Drug Interactions (7.3) and Clinical Pharm… [Excerpted — this section continues on DailyMed.]
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The most common adverse events (all grades, >10%) in subjects treated with LIVTENCITY were taste disturbance, nausea, diarrhea, vomiting, and fatigue. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Takeda Pharmaceuticals America, Inc. at 1-877-TAKEDA-7 (1-877-825-3327) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
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 practice. The safety of LIVTENCITY was evaluated in one Phase 3 multicenter, randomized, open-label, active-control trial in which 352 adult transplant recipients were randomized, and treated with LIVTENCITY (N=234) or Investigator-Assigned Treatment (IAT) consisting of monotherapy or dual therapy with ganciclovir, valganciclovir, foscarnet, or cidofovir as dosed by the investigator (N=116) for up to 8-weeks following a diagnosis of CMV infection/disease refractory to treatment (with or without genotypic resistance) with ganciclovir, valganciclovir, foscarnet or cidofovir.
The mean treatment durations (SD) for LIVTENCITY and IAT were 48.6 (± 13.82) and 31.2 (± 16.91) days, respectively. The most common adverse events occurring in more than 10% of subjects receiving LIVTENCITY are outlined in Table 2. Table 2: Adverse Events (All Grades) Reported in >10% of Subjects in the LIVTENCITY Group in Trial 303 ADVERSE EVENT LIVTENCITY N=234 (%) IAT IAT (Investigator-Assigned Treatment) included monotherapy or dual therapy with ganciclovir, valganciclovir, foscarnet, or cidofovir as dosed by the investigator.
N=116 (%) Taste disturbance taste disturbance includes the following reported preferred terms: ageusia, dysgeusia, hypogeusia and taste disorder. 46 4 Nausea 21 22 Diarrhea 19 21 Vomiting 14 16 Fatigue 12 9 Similar proportions of subjects experienced serious adverse events (38% in the LIVTENCITY group and 37% in the IAT group). The most common serious adverse event in both treatment groups occurred in the Infections and Infestations System Organ Class (SOC) (23% in the LIVTENCITY group and 15% in the IAT group) with CMV infection and disease being the most common in both groups.
A higher proportion of subjects in the IAT group discontinued study medication due to an adverse event compared to the LIVTENCITY group (32% in the IAT group vs 13% in the LIVTENCITY group). The most commonly reported causes that led to study drug discontinuation were neutropenia (9%) and acute kidney injury (5%) in the IAT group and dysgeusia, diarrhea, nausea, and recurrence of underlying disease (each reported at 1%) in the LIVTENCITY group. Taste disturbance occurred in 46% of subjects treated with LIVTENCITY.
These events rarely led to discontinuation of LIVTENCITY (1%) and, for 37% of the subjects, these events resolved while on therapy (median duration 43 days; range 7 to 59 days). For the subjects with ongoing taste disturbance after drug discontinuation, resolution occurred in 89%. In subjects with resolution of symptoms after drug discontinuation, the median duration of symptoms off treatment was 6 days (range 2 to 85 days).
Laboratory Abnormalities Selected laboratory abnormalities reported in subjects with refractory (with or without genotypic resistance) CMV infections in Trial 303 are presented in Table 3.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Refer to the full prescribing information for important drug interactions with LIVTENCITY. ( 5.1 , 5.3 , 7 ) Coadministration with strong CYP3A4 inducers is not recommended, except with a dose adjustment when coadministered with selected anticonvulsants (carbamazepine and phenytoin). When coadministered with the moderate CYP3A4 inducers rifabutin (antimycobacterial) or phenobarbital (anticonvulsant), a dose adjustment is recommended.
( 2.2 , 2.3 , 7.3 )
7.1Reduced Antiviral Activity When Coadministered with Ganciclovir or Valganciclovir LIVTENCITY is not recommended to be coadministered with valganciclovir/ganciclovir (vGCV/GCV). LIVTENCITY may antagonize the antiviral activity of ganciclovir and valganciclovir by inhibiting human CMV pUL97 kinase, which is required for activation/phosphorylation of ganciclovir and valganciclovir [see Warnings and Precautions (5.1) and Microbiology (12.4) ] .
7.2Potential for Other Drugs to Affect LIVTENCITY Maribavir is a substrate of CYP3A4. Coadministration of LIVTENCITY with strong inducers of CYP3A4 is not recommended, except with a dose adjustment when coadministered with selected anticonvulsants (carbamazepine and phenytoin). With the moderate CYP3A4 inducers, rifabutin (antimycobacterial) and phenobarbital (anticonvulsant), a dose adjustment is recommended [see Dosage and Administration (2.2 , 2.3) and Drug Interactions (7.3) ] .
For other moderate CYP3A4 inducers, the appropriate maribavir dose adjustment has not been determined.
7.3Potential for LIVTENCITY to Affect Other Drugs Maribavir is an inhibitor of P-gp and breast cancer resistance protein (BCRP). Coadministration of LIVTENCITY with drugs that are substrates of P-gp and/or BCRP where minimal concentration changes may lead to serious adverse events may result in a clinically relevant increase in plasma concentrations of these substrates (see Table 4 ) . Table 4 provides a list of established or potentially clinically significant drug interactions, based on either clinical drug interaction studies or predicted interactions due to the expected magnitude of interaction and potential for serious adverse events or decrease in efficacy [see Warnings and Precautions (5.3) and Clinical Pharmacology (12.3) ] .

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary No adequate human data are available to establish whether LIVTENCITY poses a risk to pregnancy outcomes. In animal reproduction studies, embryo-fetal survival was decreased in rats, but not in rabbits, at maribavir exposures less than those observed in humans at the recommended human dose (RHD) (see Data ) . The 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 2-4% and 15-20%, respectively. Data Animal Data In a combined fertility and embryofetal development study, maribavir was administered to male and female rats at oral doses of 100, 200, or 400 mg/kg/day. Females were dosed for 15 consecutive days prior to pairing, throughout pairing, and up to gestation day (GD) 17, while males were dosed 29 days prior to mating and throughout mating.
A decrease in the number of viable fetuses and increase in early resorptions and post-implantation losses were observed at ≥100 mg/kg/day (at exposures approximately half the human exposure at the RHD). Intermittent reduced body weight gain was observed in pregnant animals at ≥200 mg/kg/day. Maribavir had no effect on embryo-fetal growth or development at dose levels up to 400 mg/kg/day, at exposures similar to those observed in humans at the RHD.
No significant toxicological effects on embryo-fetal growth or development were observed in rabbits when maribavir was administered at oral doses up to 100 mg/kg/day from GD 8 to 20, at exposures approximately half the human exposure at the RHD. In the pre-and post-natal developmental toxicity study, maribavir was administered to pregnant rats at oral doses of 50, 150, or 400 mg/kg/day from GD 7 to post-natal day (PND) 21. A delay in developmental milestones was observed, including pinna detachment at doses ≥150 mg/kg/day and eye opening and preputial separation associated with reduced bodyweight gain of the offspring at 400 mg/kg/day.
In addition, decreased fetal survival and litter loss was observed due to maternal toxicity and poor maternal care, respectively, at doses ≥150 mg/kg/day. No effects were observed at 50 mg/kg/day (which is estimated to be less than the human exposure at the RHD). No effects on number of offspring, proportion of males, number of live pups, or survival to PND 4 were observed at any dose in the offspring born to the second generation.
8.2Lactation Risk Summary It is not known whether maribavir or its metabolites are present in human or animal milk, affect milk production, or have effects on the breastfed infant. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for LIVTENCITY and any potential adverse effects to the breast-fed child.
8.4Pediatric Use The recommended dosing regimen in pediatric patients 12 years of age and older and weighing at least 35 kg is the same as that in adults. Use of LIVTENCITY in this age group is based on the following: Evidence from controlled studies of LIVTENCITY in adults Population pharmacokinetic (PK) modeling and simulation demonstrating that age and body weight had no clinically meaningful effect on plasma exposures of LIVTENCITY LIVTENCITY exposure is expected to be similar between adults and children 12 years of age and older and weighing at least 35 kg The course of the disease is similar between adults and pediatric patients to allow extrapolation of data in adults to pediatric patients [see Dosage and Administration (2.1) , Clinical Pharmacology (12.3) and Clinical Studies (14) ] The safety and effectiveness of LIVTENCITY have not been established in children younger than 12 years of age.

🧓 Geriatric Use ▾
8.5Geriatric Use No dosage adjustment is required for patients over 65 years of age based on the results from population pharmacokinetics analysis [see Clinical Pharmacology (12.3) ] and efficacy and safety data from the clinical studies. In the clinical Study 303, 54 patients aged 65 years and over were treated with LIVTENCITY. Safety, effectiveness, and pharmacokinetics were consistent between elderly patients (≥65 years) and younger patients (<65 years).
🆘 Overdosage ▾
10 OVERDOSAGE There is no known specific antidote for LIVTENCITY. In case of overdose, it is recommended that the patient be monitored for adverse reactions and appropriate symptomatic treatment instituted. Due to the high plasma protein binding of LIVTENCITY, dialysis is unlikely to reduce plasma concentrations of LIVTENCITY significantly.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action LIVTENCITY is an antiviral drug against human CMV [see Microbiology (12.4) ] .
12.2Pharmacodynamics Exposure-Response In dose-ranging studies that evaluated doses of 400 mg twice daily and twice daily doses of two and three times the recommended dose, no exposure-response relationship was observed for viral load or probability of unquantifiable plasma CMV DNA. In Phase 3 Trial 303 that evaluated a maribavir dose of 400 mg twice daily, increasing maribavir exposure was not associated with increased probability of confirmed plasma CMV DNA < LLOQ (lower limit of quantification) at Week 8. Cardiac Electrophysiology At three times the recommended dose (approximately twice the peak concentration observed following the recommended dose), LIVTENCITY does not prolong the QT interval to any clinically relevant extent.
12.3Pharmacokinetics LIVTENCITY pharmacological activity is due to the parent drug. Following oral administration, plasma maribavir exposure (C max and AUC) increased approximately dose-proportionally following a single dose of 50 to 1600 mg (0.125 to four times the recommended dose) and multiple doses up to 2400 mg per day (three times the recommended daily dose). Maribavir PK is time-independent.
With twice-daily dosing, steady state is reached within 2 days, with mean accumulation ratios of C max and AUC ranging from 1.37 to 1.47. The pharmacokinetic properties of maribavir following administration of LIVTENCITY are displayed in Table 5. The multiple-dose pharmacokinetic parameters are provided in Table 6.

14 CLINICAL STUDIES
14.1Treatment of Adults with Post-Transplant CMV Infection/Disease That Is Refractory (with or without Genotypic Resistance) to Ganciclovir, Valganciclovir, Cidofovir, or Foscarnet LIVTENCITY was evaluated in a Phase 3, multicenter, randomized, open-label, active-controlled superiority trial (NCT02931539, Trial 303) to assess the efficacy and safety of LIVTENCITY compared to Investigator-Assigned Treatment (IAT) (ganciclovir, valganciclovir, foscarnet, or cidofovir) in 352 HSCT or SOT recipients with CMV infections that were refractory to treatment with ganciclovir, valganciclovir, foscarnet, or cidofovir, including CMV infections with or without confirmed resistance to 1 or more of the IATs.
Subjects with CMV disease involving the central nervous system, including the retina, were excluded from the study. Subjects were stratified by transplant type (HSCT or SOT) and screening CMV DNA levels and then randomized in a 2:1 allocation ratio to receive either LIVTENCITY 400 mg twice daily or IAT as dosed by the investigator for up to 8 weeks. After completion of the treatment period, subjects entered a 12-week follow-up phase.
The mean age of trial subjects was 53 years and most subjects were male (61%), white (76%) and not Hispanic or Latino (83%), with similar distributions across the two treatment arms. The most common treatment used in the IAT arm was foscarnet which was administered in 47 (41%) subjects followed by ganciclovir or valganciclovir, each administered in 28 (24%) subjects. Cidofovir was administered in 6 subjects, the combination of foscarnet and valganciclovir in 4 subjects and the combination of foscarnet and ganciclovir in 3 subjects.

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Two-year carcinogenicity studies were conducted in mice and rats administered oral doses up to 150 and 100 mg/kg/day, respectively. Maribavir was not carcinogenic in rats at any dose tested, corresponding to maribavir exposures less than human exposure at the RHD. At 150 mg/kg/day in male mice only, an increased incidence of hemangioma, hemangiosarcoma, and combined hemangioma/hemangiosarcoma was observed across multiple tissues, at exposures less than the human exposure at the RHD.
There were no carcinogenic findings in male mice at ≤75 mg/kg/day and female mice at any dose. Mutagenicity Maribavir was negative in a bacterial mutation assay and the in vivo rat bone marrow micronucleus assay. Maribavir was positive in the absence of metabolic activation in the mouse lymphoma assay, and the results were equivocal in the presence of metabolic activation.
Impairment of Fertility Although decreased sperm straight line velocity was observed in males (at maribavir exposures less than those observed in humans at the RHD), there were no effects on fertility in males or females in a combined oral fertility and embryo-fetal study in rats administered maribavir at up to 400 mg/kg/day [see Use in Specific Populations (8.1) ] .
