Description
Oral kinase inhibitor against multiple targets, including vascular endothelial growth factor receptors
Used for advanced endometrial cancer, radioactive iodine refractory differentiated thyroid cancer, advanced renal cell carcinoma, and unresectable hepatocellular carcinoma
May cause QT prolongation; avoid other drugs that cause QT prolongation
Dosage And Indications
24 mg orally once daily with or without food until disease progression or unacceptable toxicity. In a multicenter, randomized, double-blind, placebo-controlled clinical trial, treatment with lenvatinib (n = 261) significantly improved progression free survival (18.3 months vs. 3.6 months) and objective response rate (65% vs. 2%) compared with placebo (n = 131) in patients with locally recurrent or metastatic, progressive, radioactive iodine-refractory differentiated thyroid cancer. Overall survival was not estimable in either group, with a hazard ratio of 0.73. Of note, 83% of patients randomly assigned to placebo crossed over to receive open-label lenvatinib upon progression, which may have affected overall survival.
18 mg orally once daily, in combination with everolimus 5 mg orally once daily. Continue until disease progression or unacceptable toxicity. In a multicenter, open-label, phase 2 clinical trial, patients with advanced or metastatic renal cell carcinoma (RCC) who had received prior anti-angiogenic therapy were randomized to treatment with lenvatinib plus everolimus (combination therapy, n = 51), or everolimus monotherapy (10 mg per day, n = 50). The primary outcome of investigator-assessed median progression-free survival (PFS) was significantly improved in patients receiving combination therapy compared with everolimus monotherapy (14.6 months vs. 5.5 months); this was supported by a retrospective independent review of radiographs with an observed hazard ratio of 0.43 (95% CI, 0.24 to 0.75). Additionally, the median overall survival was 25.5 months with combination therapy compared with 15.4 months in patients treated with everolimus monotherapy (HR 0.67; 95% CI, 0.42 to 1.08) and the objective response rate was 37% versus 6%, respectively; all but one response (in a patient who received combination therapy) were partial responses.
20 mg orally once daily, in combination with pembrolizumab (200 mg IV every 3 weeks OR 400 mg IV every 6 weeks until disease progression or for up to 24 months in patients without disease progression). After 2 years of combination therapy, lenvatinib may be continued as a single agent until disease progression or unacceptable toxicity. The primary outcome of investigator-assessed median progression-free survival time was significantly improved with lenvatinib plus pembrolizumab compared with sunitinib (23.9 months vs. 9.2 months; hazard ratio (HR) = 0.39; 95% CI, 0.32 to 0.49; p less than 0.001) in patients with previously untreated advanced RCC with a clear-cell component in a 3-arm, randomized (1:1:1), phase 3 trial (the CLEAR trial; n = 1,069). At a median follow-up time of 26.6 month, the overall survival time was significantly longer in the lenvatinib plus pembrolizumab arm compared with the sunitinib arm (median time not reached in either arm; HR = 0.66; 95% CI, 0.49 to 0.88; P = 0.005).
12 mg PO once daily until disease progression or unacceptable toxicity. In a multicenter, randomized, open-label clinical trial of patients with previously untreated unresectable hepatocellular carcinoma (HCC), treatment with lenvatinib was noninferior to sorafenib therapy for overall survival (13.6 months vs. 12.3 months). Median progression-free survival (7.3 months vs. 3.6 months) and objective response rate (ORR) were significantly improved in the lenvatinib arm. The ORR was 41% in the lenvatinib arm compared with 12% in those treated with sorafenib using modified RECIST criteria (complete response (CR), 2.1% vs. 0.8%; partial response (PR), 38.5% vs. 11.6%). Using RECIST 1.1 criteria, the ORR was 19% versus 7%, respectively (CR, 0.4% vs. 0.2%; PR, 18.4% vs. 6.3%).
8 mg PO once daily until disease progression or unacceptable toxicity. In a multicenter, randomized, open-label clinical trial of patients with previously untreated unresectable hepatocellular carcinoma (HCC), treatment with lenvatinib was noninferior to sorafenib therapy for overall survival (13.6 months vs. 12.3 months). Median progression-free survival (7.3 months vs. 3.6 months) and objective response rate (ORR) were significantly improved in the lenvatinib arm. The ORR was 41% in the lenvatinib arm compared with 12% in those treated with sorafenib using modified RECIST criteria (complete response (CR), 2.1% vs. 0.8%; partial response (PR), 38.5% vs. 11.6%). Using RECIST 1.1 criteria, the ORR was 19% versus 7%, respectively (CR, 0.4% vs. 0.2%; PR, 18.4% vs. 6.3%).
NOTE: Select patients for treatment based on MSI-H or MMR status in tumor specimens.
Oral dosage Adults
20 mg PO once daily until disease progression, in combination with pembrolizumab (200 mg IV every 3 weeks OR 400 mg IV every 6 weeks until disease progression or for up to 24 months in patients without disease progression). Coadministration of certain drugs may need to be avoided or dosage adjustments may be necessary; review drug interactions. Treatment with pembrolizumab plus lenvatinib significantly improved the median progression-free survival (6.6 months vs. 3.8 months) and overall survival (17.4 months vs. 12 months) compared with doxorubicin or paclitaxel in patients with advanced endometrial cancer who had been previously treated with at least one prior platinum-based chemotherapy regimen in any setting and were pMMR or not MSI-H in a multicenter, randomized, open-label clinical trial (KEYNOTE-775). The objective response rate was also significantly improved in the pembrolizumab/lenvatinib arm (30% vs. 15%; complete response, 5% vs. 3%) for a median duration of 9.2 months versus 5.7 months, respectively.
Dosing Considerations
Baseline Hepatic Impairment
Mild-to-moderate hepatic impairment (Child-Pugh Class A or B): no dosage adjustment needed for patients with DTC or RCC. There is no recommended dose for patients with HCC who have moderate hepatic impairment.
Severe hepatic impairment (Child-Pugh Class C): Reduce the starting dose for DTC to 14 mg PO once daily; reduce the starting dose for endometrial cancer and RCC to 10 mg PO once daily. There is no recommended dose for patients with HCC who have severe hepatic impairment.
Treatment-Related Hepatotoxicity
Grade 3 or 4 hepatotoxicity: Hold lenvatinib therapy. When hepatic function improves to grade 0, 1, or baseline, either resume lenvatinib therapy at a reduced dose per the above recommendations, or discontinue therapy depending on severity and persistence of hepatotoxicity. For RCC patients receiving combination therapy with everolimus, adjust or discontinue only the everolimus therapy if the toxicity is thought to be solely due to everolimus. If the toxicity is likely related to both lenvatinib and everolimus, first reduce lenvatinib and then everolimus.
Hepatic failure: Permanently discontinue lenvatinib.[58782]
Baseline Renal Impairment
CrCL greater than or equal to 30 mL/min: no dosage adjustment needed.
CrCL less than 30 mL/min: Reduce the starting dose for DTC to 14 mg PO once daily; reduce the starting dose for endometrial cancer and RCC to 10 mg PO once daily. There is no recommended dose of lenvatinib for patients with HCC and severe renal impairment.
End-stage renal disease: Recommendations not available; patients with end-stage renal disease were not studied.
Treatment-Related Nephrotoxicity
Grade 3 or 4 renal impairment, or renal failure: Hold lenvatinib therapy. When renal function improves to grade 0, 1, or baseline, either resume lenvatinib therapy at a reduced dose per the above recommendations or discontinue therapy depending on the severity and persistence of renal impairment. For RCC patients receiving combination therapy with everolimus, adjust or discontinue only the everolimus therapy if the toxicity is thought to be solely due to everolimus. If the toxicity is likely related to both lenvatinib and everolimus, first reduce lenvatinib and then everolimus.
Proteinuria (2g or greater in 24 hours): Hold lenvatinib therapy. When there is less than or equal to 2 g of proteinuria per 24 hours, resume lenvatinib therapy at a reduced dose per the recommendations above.
Nephrotic syndrome: Permanently discontinue lenvatinib therapy.[58782]
Drug Interactions
Adagrasib: (Major) Concomitant use of adagrasib and lenvatinib increases the risk of QT/QTc prolongation and torsade de pointes (TdP).

Mechanism Of Action
Lenvatinib is a kinase inhibitor, inhibiting the kinase activities of vascular endothelial growth factor receptor 1 (VEGFR1; FLT1), VEGFR2 (KDR), and VEGFR3 (FLT4). Lenvatinib also inhibits other kinases that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression including fibroblast growth factor receptors 1 (FGFR1), FGFR2, FGFR3, and FGFR4, platelet-derived growth factor receptor alpha (PDGFR-alpha), KIT, and RET. It also exhibited antiproliferative activity in hepatocellular carcinoma cell lines dependent on activated FGFR signaling with a concurrent inhibition of FGF-receptor substrate 2 alpha (FRS2 alpha) phosphorylation. The combination of lenvatinib and everolimus showed increased anti-angiogenic and anti-tumor activity (decreased endothelial cell proliferation, tube formation, and VEGF signaling, as well as tumor volume) in mouse xenograft models of human renal cell carcinoma, greater than each drug alone.[58782]
Pharmacokinetics
Lenvatinib is administered orally. Lenvatinib is 97% to 99% bound in vitro to human plasma proteins independent of drug concentration; in vitro, the blood-to-plasma concentration ratio was 0.59 to 0.61 (0.1 to 10 micrograms/mL). The model-predicted geometric mean steady-state volume of distribution was 97 L (coefficient of variation (CV), 30.2%) and the terminal elimination half-life was approximately 28 hours. The main metabolic pathways are enzymatic (CYP3A and aldehyde oxidase) and non-enzymatic. Radiolabeled lenvatinib was administered to 6 patients with solid tumors; after 10 days, approximately 64% and 25% of the dose were eliminated in the feces and urine, respectively.
A dose-response relationship has been observed for overall response rate over the range of 18 mg to 24 mg in patients with radioactive iodine-refractory differentiated thyroid cancer in a randomized clinical trial (n = 152). No dose-response relationships were observed for adverse reactions over the same dose range.
Affected cytochrome P450 (CYP450) isoenzymes and drug transporters: CYP3A, P-glycoprotein (P-gp), breast cancer resistance protein (BCRP)
CYP3A is one of the main metabolic pathways for lenvatinib; in vitro, lenvatinib is also a P-gp and BCRP substrate. When administered with ketoconazole (a CYP3A, P-gp, and BCRP inhibitor) in a dedicated clinical trial, the AUC and Cmax of lenvatinib increased by 15% and 19%, respectively. Administration with rifampin as a single dose increased the AUC (31%) and Cmax (33%) of lenvatinib, but reduced the AUC by 18% when administered daily for 21 days (no change to the Cmax). The concomitant use of lenvatinib with midazolam, a sensitive CYP3A4 substrate, had no effect on the pharmacokinetic parameters of midazolam. Lenvatinib inhibits CYP2C8, CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, and CYP3A in vitro; lenvatinib also induces CYP3A. Lenvatinib inhibits UGT1A1, UGT1A4, and UGT1A9 in vitro, but likely only inhibits UGT1A1 in vivo in the gastrointestinal tract based on the expression of the enzyme in tissues.[58782]
The geometric mean steady-state Cmax and AUC values were 323 nanogram (ng)/mL (coefficient of variation (CV), 33.3%) and 3,483 ng x hour/mL (CV, 34.7%), respectively, in 251 patients with differentiated thyroid cancer who received lenvatinib 24 mg/day. The Cmax values were 267 ng/mL (CV, 36.7%) and 275 ng/mL (CV, 32.6%) in patients with renal cell carcinoma who received lenvatinib 18 mg/day (n = 350) and 20 mg/day (n = 346), respectively; the AUC values were 3,148 ng x hour/mL (CV, 42.5%) and 3,135 ng x hour/mL (CV, 41.3%), respectively. The Cmax values were 154 ng/mL (CV, 25.4%) and 172 ng/mL (CV, 23.1%) in patients with hepatocellular carcinoma who received lenvatinib 8 mg/day (n = 150) and 12 mg/day (n = 318), respectively; the AUC values were 1,835 ng x hour/mL (CV, 34%) and 2,013 ng x hour/mL (CV, 29.3%), respectively. Cmax and AUC values increased proportionally over the dose range of 3.2 to 32 mg, with a median accumulation index of 0.96 (20 mg) to 1.54 (6.4 mg). Peak plasma concentrations of lenvatinib (Tmax) are observed 1 to 4 hours after oral administration.
Effect of food: Administration with a high-fat meal (approximately 900 calories; fat, 55%; protein, 15%; carbohydrates, 30%) does not affect the extent of absorption but decreases the rate of absorption and delays the median Tmax from 2 to 4 hours.
Pregnancy And Lactation
Fetal harm may occur if lenvatinib is administered during pregnancy, based on animal studies. The use of effective contraception is recommended to avoid pregnancy during treatment and for 30 days following the last dose. No human data are available regarding teratogenic risk. Women who become pregnant while receiving lenvatinib should be apprised of the potential hazard to the fetus. During the period of organogenesis, exposures of 0.14 and 0.03 times the human exposure at the recommended dose resulted in reduced fetal body weights and an increased incidence of external, visceral, and skeletal variations in rats and rabbits, respectively. Post-implantation loss occurred in more than 80% of rats at approximately 0.5 times the recommended human dose based on BSA; increased post-implantation loss, including 1 fetal death, occurred at exposures of 0.03 times the recommended human dose based on BSA in rabbits. Additionally, late abortions occurred in approximately one-third of rabbits at approximately 0.5 times the recommended human dose based on BSA.[58782]
Counsel patients about the reproductive risk and contraception requirements during lenvatinib treatment. Lenvatinib can be teratogenic if taken by the mother during pregnancy. Females of reproductive potential should avoid pregnancy and use effective contraception during and for 30 days after treatment with lenvatinib. Females of reproductive potential should undergo pregnancy testing prior to initiation of lenvatinib. Women who become pregnant while receiving lenvatinib should be apprised of the potential hazard to the fetus. Although there are no data regarding the effect of lenvatinib on human fertility, male and female infertility has been observed in animal studies.[58782]
