Lenvatinib 4 mg & 10 mg

LENVAXEN 4 capsules: Each capsule contains Lenvatinib Mesylate INN equivalent to Lenvatinib 4 mg.

LENVAXEN 10 capsules Each capsule conlains Lenvatinib Mesylate INN equivalent to Lenvatinib 10 mg.

Lenvatinib is indicated as monotherapy for the treatment of adult patients with progressive, IocaIIy advanced or metastatic, differenliated (papillary/foIIicuIar/Hürthle cell) thyroid carcino- ma (DTC), refractory to radioactiva iodine (RAI). Lenvatinib is indicated as monotherapy for the treatment of adult patients with advanced or unresectable hepatocellular carcinoma (HCC) who have received no prior systemic therapy.
Recommended Dosage for Ditferentiated Thyroid Cancer (DTC)
The recommended dosage of lenvatinib is 24 mg orally once daily until disease progression or until unacceptable toxicity.

Recommended Dosage for Renal Cell Carcinoma (RCC) The recommended dosage of lenvatinib is 18 mg in combina- tion wilh 5 mg everolimus orally once daily until disease progression or until inacceptable toxicity.

Refer to everolimus prescribing information for recommended everolimus dosing intormation.

Recommended Dosage for Hepatocellular Carcinoma
The recommended dosage of lenvatinib is based on actual body weight, 12 mg for patients greater than or equal to 60 kg or 8 mg for patients less than 60 kg. Take lenvatinib orally once daily until disease progression or until unacceptable toxicity.

Reduce the dose for certain patients with renal or hepatic impairment. Take lenvatinib once daily, with or without food, at the same time each day. If a dose is missed and cannot be taken within 12 hours, skip that dose and take the next dose at the usual time of administration.

Management of some adverse reactions may require dose interruption, ad]ustment, or discontinuation of lenvatinib therapy. Mild to moderate adverse reactions (e.g., Grade 1 or
2) generalIy do not warrant interruption of lenvatinib, unless intolerable to the patient despite optimal management. Details for monitoring, dose adjustment and discontinuation are provid- ed in Table 1 & 2

Elderïy population DTC
Patients of age 75 years, of Asian race, with comorbidities (such as hypertension, and hepatic or renal impairment), or body weight below 60 kg appear to have reduced tolerability to lenvatinib. AII patients other lhan those with severe hepatic or renal impairment should initiate treatment at the recommended
24 mg dose, followTng which the dose should be further adjusted on the basis of individual tolerability.

Patients 75 years, of white race or female sex or those with worse baseline hepatic impairment (Child-Pugh A score of 6 compared to score of 5) appear to have reduced tolerability to lenvatinib.

HCC patients other than those with moderate and severe hepatic impairment or severe renal impaTrment should initiate treatment at the recommended starling dose of 8 mg (two 4 mg capsules) for body weight‹ 60 kg and 12 mg (three 4 mg capsules) for body weTghl 60 kg, following which the dose should be further ad¡usted on the basis of individual tolerability

Patients with hypertension
Blood pressure should be well controlled prior to treatment with lenvatinib and should be regularly monitored during treatment.

Patients with hepatic impairment DTC
No adjustment of starting dose is required on the basis of hepatic function in patients with mild (Child-Pugh A) or moder- ats (Child-Pugh B) hepatic impairment In patients with severe (Child-Pugh C) hepatic impairmenl, Ihe recommended starting dose is 14 mg taken once daily. Further dose adjustments may be necessari on the basis of individual tolerability.

In Ihe patient populations enrolled in the HC:C study no dose adjustments were required on the basis of hepatic function in those patients who had mild hepatic impairment (Child-Pugh A). The available very limited data are not sufficient to allow for a dosing recommendation for HCC patients with moderats hepatic impairment (Child-Pugh B). Close monitoring of overall
Patients with renal impairment DTC
No adjustment of starting dose is required on the basis of renal function in palients wilh mild or moderate renal impairment. In patients with severe renal impairment, the recommended starting dose is 14 mg taken once daily. Further dose adjustments may be necessary based on individual tolerability. Patients with end-stage renal disease were nol studied, therefore the use of lenvatinib in these patients is not recom- mended.

No dose adjustments are required on the basis of renal function in patients with mild or moderate renal impairment. The available data do not allow for a dosing recommendation for patients with HCC and severe renal impairment.

Effect of Lenvatinib on other medicine
A clinical drug-drug interaction (DDI) study in cancer pacients showed that plasma concentracions of midazolam (a sensitive CYP3A and Pgp substrate) were not altered in the presence of lenvatinib. No significant drug-drug interaction is therefore expected between lenvatinib and other CYP3A4/Pgp subslrates.

Oral contraceptives
It is currently unknown whether lenvatinib may reduce the effectiveness of hormonal contraceptives and therefore women using oral hormonal contraceptives should add a barrier method.

Women of childbearing potential
Women ol childbearing potenlial should avoid becoming pregnanl and use highly effeclive contraception while on treatment with lenvatinib and for at least one month alter linishing treatment It is currently unknown whether lenvatinib may reduce the effective- ness of hormonal contraceptives, and therelore women using oral hormonal contraceptives should add a barrier melhod

There are no data on the use ot lenvatinib in pregnant women. Lenvatinib was embryotoxic and teratogenic when administered to rats and rabbits. Lenvatinib should not be used during pregnancy unless clearly necessary and after a careful consid- eration of the needs of the mother and the risk to the foetus.

It is nol known whether lenvatinib is excreted in human milk. Lenvatinib and its metabolites are excreted in rat milk. A risk to newborns or infants cannot be excluded and, therelore, IenvatTnib is contraindicated during breast-feeding.

Eflects in humans are unknown. However, testicular and ovarian
toxicity has been observed in raÏs, dogs, and monkeys.

Patients with Renal lmpairment
The pharmacokinetics of lenvatinib lollowing a single 24 mg dose were evaluated in sub ects with mild (CLcr 60-89 mL/mín), moderats (CLcr 30-59 mL/min), or severe (CLcr x30 mL/min) renal impairment, and compared to healthy subjects. Subjecta with end stage renal disease were not studied. The AUC(‹’ .rï) for subjects with renal impairment were similar compared to those for healthy subjecta.

Patients with Hepetic lmpairment
The pharmacokinetics of lenvatinib following a single 10 mg dose were evaluated in subjecta with mild (Child-Pugh A) or moderats (Child-Pugh B) hepatic impairment. The pharmacoki- netics of a single 5 mg dose were evaluated in sub]ects wilh severe (Child-Pugh C) hepatic impairment. Compared to subjects with normal hepatic function, the dose-adjusted AUC(‹’ .r ) of lenvatinib for subjecta with mild, moderate, and severe hepatic impairment were 119P•, 107°ü, and 180%, respectively. Apparent oral clearance of lenvatinib in patients with HCC and mild hepatic impairment was similar to patients with HCC and moderate hepatic impairment.

Paediatric Population
Paediatric patients have not been studied.
The highest doses of lenvatinib studied clinically were 32 mg and 40 mg per day. Accidental medication errors resulting in single doses of 40 to 48 mg have occurred in clinical mials. The most frequently observed adverse drug reactions at these doses were hypertension, nausea, diarrhoea, fatigue, stomatitis, proteinuria, headache, and aggravation of PPE. There have also been reports of overdose with lenvatinib involving single administrations of 6 to 10 times the recommended daily dose. Ihese cases were associated with adverse reactions consistenl with the known safety profile of lenvatinib (i.e., renal and cardiac failure), or were without adyerse reactions.

Lenvatinib, a kinase inhibitor, is the mesylate salt of lenvatinib Its chemical name is 4-[3chIoro-4-(N’-cyclopropylureido) phenoxy]
-7-methoxyquinoIine-6-carboxamide methanesulfonate. The molecular formula is CzJ HJaCIN4O4 CH4OzS, and the molecular weight of the mesylale salt is 522.96. The chemical structure ot lenvatinib mesylate is


Lenvatinib mesylate is a white to pale reddish yellow powder. It is slighlly soluble in water & insoluble in ethanol (dehydrated). The dissociation constant (pKa value) of lenvatinib mesylate is
5.05 at 25°C. The panition coefficient (log P value) is 3.3.

Mech8niam of Action
Lenvatinib is a receptor tyrosine kinase (RTK) inhibitor that selectively inhibits the kinase activities of vasc ular endothelial growth factor (VEGF) receptors VEGFR1 (FLT1), VEGFR2 (KDR), and VEGFR3 (FLT4), in addition to other proangiogenic and oncogenic pathway-related RTKs including fibroblast growth factor (FGF) receptors FGFR1, 2, 3, and 4, Ihe platelet derived growth factor (PDGF) receptor PDGFRa, KIT, and RET.

In addition, lenvatinib had selective, direct antiproliferative activity in hepatocellular cell lines dependent on activated FGFR signalling, which is arributed to the inhibition of FGFR signalling by lenvatinib

Although not studied directly wilh lenvatinib, Ihe mechanism of action (MOA) for hypertension is postulated to be mediated by the inhibition of VEGFP2 in vascular endothelial cells. Similarly, although not studied directly, the MOA Ïor proteinuria is postulat- ed to be mediated by downregulalion of VEGFR1 and VEGFR2 in the podocytes of the glomerulus.

Pharmacokinetic properties
Pharmacokinetic parameters of lenvatinib have been studied in healthy adult subjecta, adult subjecta with hepatic impairment, renal impairment, and solid tumours.

Lenvatinib is rapidly absorbed after oral administration with Tram lypically observed from 1 to 4 hours postdose. Food does nol affect the extent of absorption but slows the rate of absorption. When administered wilh food to healthy subjecta, peak plasma concentracions are delayed by 2 hours. Absolute bioavailability has not been determined in humans; however, data from a mass-balance study suggest that it is in the order of 85%. Lenvatinib exhibited good oral bioavailability in dogs (70.4R ) and monkeys (78.4%).

in vitro binding of lenvatinib to human plasma proteins is high and ranged Irom 98°ü to 99% (0.3 – 30 pg/mL, mesylate). This binding was mainly to albumin with minor binding to a1-acid glycoprotein and y-globulin.

In vitro, the lenvatinib blood-lo-plasma concenlration ratio ranged from 0.589 to 0.608 (0.1— 10 Ag/mL, mesylate).

Lenvatinib is a substrate lor P-gp and BCRP Lenvatinib is not a substrate for OAT1, OAT3, OATP1B1, OATP1B3, OCT1, OCT2,
MATE1, MATE2-K or the bile salt export pump BSEP.

In patients, the median apparent volume of distribution (Vz/F) of the first dose ranged trom 50.5 L to 92 L and was generally consistent across the dose groups from 3.2 mg to 32 mg. The analogous median apparent yoIume of distribution at steady-state (Vz/Fss) was also generally consistent and ranged from 43 2 L to 121 L

in vitro, cytochrome P450 3A4 was demonstrated as lhe predominant (›80%) isoform involved in the P450-mediated metabolism of lenyatinib. However, in aivo data indicated that non-P450-mediated pathways conlrTbuted to a significant porlion of Ihe overall metabolism of lenvatinib Consequently, in vivo, inducers and inhibitors ol CYP 3A4 had a minimal effect on lenvatinib exposure.

In human liver microsomes, lhe demethylated form ot lenvatinib (M2) was identified as the main metabolite. M2’ and M3′, the ma or metabolites in human faeces, were formed from M2 and lenvatinib, respectively, by aldehyde oxidase

In plasma samp les collected up to 24 hours after adminislration, lenvatinib constiÏuted 97% oÏ the radioactivity in plasma radiochromatograms while the M2 metabolite accounted for an addicional 2.5%. Based on AUC‹— »‹›, lenvatinib accounted for 60% and 64″ó ol the total radioactiyity in plasma and blood, respectively.

Plasma concentrations decline bi-exponentially following Com. Ihe mean terminal exponenlial half-life of lenvatinib is approxi- mately 28 hours.

Following administration of radiolabelled lenvatinib to 6 patients wilh solid tumours, approximately two-thirds and one-quarter of the radiolabel were eliminated in lhe faeces and urine, respec- tively The M3 metabolite was the predominant analyte in excrela (-17% of the dose), lollowed by M2′ (-11R ot the dose) and M2 (-4.4 of the dose)

Carcinogenesis, mutagenesis, impairment of fertility carcinoge- nicity studies have not been conducted with lenvatinib Lenvali- nib mesylate was not mutagenic in the in vitro bacterial reverse mutation (Ames) assay. Lenvatinib was not clasïogenic in the n vitro mouse lymphoma thymidine kinase assay or the n v/vo rat micronucleus assay. No specific studTes with lenvatinib haye been conducted in animals to evaluate the effect on ferlility; however, results from general toxicology studies in rats, monkeys, and dogs suggest there is a potential for lenvatinib lo impair fertility. Male dogs exhibiled testicular hypocellularity of the seminiferous epithelium and desquamated seminiferous epithelial cells in the epididymides at lenvatinib exposures approximately 0.02 to 0.09 times the AUC at the recommended clinical dose of 24 mg once daily. Follicular atresia of the ovaries was observed in monkeys and rats at exposures 0.2 to 0 8 times and 10 to 44 times the AUC at the recommended clinical dose of
24 mg once daily, respectively. In addition, in monkeys, a decreased incidence of menstruation was reported at lenvatinib exposures lower than those observed in humans at the recommended clinical dose of 24 mg once daily.
