Fotivda 1340mcg hard capsules

Fotivda is indicated for the first line treatment of adult patients with advanced renal cell carcinoma (RCC) and for adult patients who are VEGFR and mTOR pathway inhibitor-naï ve following disease progression after one prior treatment with cytokine therapy for advanced RCC.

Fotivda should be supervised by a physician experienced in the use of anticancer therapies.

Posology

The recommended dose of tivozanib is 1340 microgram once daily for 21 days, followed by a 7-day rest period to comprise one complete treatment cycle of 4 weeks.

This treatment schedule should be continued until disease progression or unacceptable toxicity.

No more than one dose of Fotivda must be taken per day.

Dose modification

The occurrence of undesirable effects may require temporary interruption and/or dose reduction of tivozanib therapy (see section 4.4). In the pivotal study, the dose was reduced for grade 3 events and interrupted for grade 4 events.

When dose reduction is necessary, the tivozanib dose can be reduced to 890 microgram once daily with the normal treatment schedule of 21 days of dosing, followed by a 7-day rest period.

Missed dose

In the case of a missed dose a replacement dose must not be taken to make up for a forgotten dose. The next dose should be taken at the next scheduled time.

In the case of vomiting a replacement dose should not be taken; the next dose should be taken at the next scheduled time.

Special populations

Paediatric population

The safety and efficacy of tivozanib in children and adolescents aged below 18 years have not been established. No data are available. There is no relevant use of tivozanib in the paediatric population in the indication advanced renal cell carcinoma.

Elderly patients

No dose adjustment is required in patients 65 years of age or older (see sections 4.4 and 5.1).

Patients with renal impairment

No dose adjustment is required in patients with mild or moderate renal impairment (see section 5.2). Caution is advised in patients with severe renal impairment due to limited experience and in patients undergoing dialysis as there is no experience of tivozanib in this patient population.

Patients with hepatic impairment

All patients should have liver function tests evaluated, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, and alkaline phosphatase (AP), to determine hepatic function before starting and during treatment with tivozanib.

Tivozanib is not recommended in patients with severe hepatic impairment. Patients with moderate hepatic impairment should only be treated with one tivozanib 1340 microgram capsule every other day as they may be at an increased risk of adverse reactions due to increased exposure with the dose of 1340 microgram every day (see section 4.4 and section 5.2). No dose adjustment is required when administering tivozanib to patients with mild hepatic impairment. Tivozanib should be used with caution in patients with mild and moderate hepatic impairment with close monitoring of tolerability.

Method of administration

Fotivda is for oral use.

Fotivda may be taken with or without food (see section 5.2). The capsules must be swallowed whole with a glass of water and must not be opened.

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Co-administration with herbal preparations containing St. John's wort (Hypericum perforatum) (see section 4.5).

Hypertension

In clinical studies with tivozanib, hypertension (including persistent severe hypertension) has occurred (see section 4.8). In approximately one-third of the patients, hypertension developed within the first 2 months of treatment. Blood pressure should be well controlled prior to initiating tivozanib. During treatment, patients should be monitored for hypertension and treated as needed with anti-hypertensive therapy according to standard medical practice. In the case of persistent hypertension despite use of anti-hypertensive therapy, the tivozanib dose should be reduced, or the treatment interrupted and re-initiated at a lower dose once the blood pressure is controlled, according to clinical judgment (see section 4.2). Discontinuation of treatment should be considered in cases of persistent severe hypertension, posterior reversible encephalopathy syndrome (see below), or other complications of hypertension. Patients receiving anti-hypertensive medicinal product should still be monitored for hypotension when tivozanib is either interrupted or discontinued.

Arterial thromboembolic events

In clinical studies with tivozanib, arterial thromboembolic events (ATEs) have occurred (see section 4.8). Risk factors for ATE include malignant disease, age > 65 years, hypertension, diabetes mellitus, smoking, hypercholesterolaemia, and prior thromboembolic disease. Tivozanib has not been studied in patients who had an ATE within the preceding 6 months of clinical study initiation. Tivozanib must be used with caution in patients who are at risk for, or who have a history of these events (such as myocardial infarction, stroke).

Venous thromboembolic events

In clinical studies with tivozanib, venous thromboembolic events (VTEs) have been reported including pulmonary embolism and deep vein thrombosis (see section 4.8). Risk factors for VTEs include major surgery, multiple trauma, prior VTEs, advanced age, obesity, cardiac or respiratory failure, and prolonged immobility. Tivozanib has not been studied in patients who had a VTE within the preceding 6 months of clinical study initiation. Treatment decision, especially in patients who are at risk for VTEs, should be based on individual patient benefit/risk assessment.

Cardiac failure

In clinical studies with tivozanib as monotherapy for the treatment of patients with RCC, cardiac failure has been reported (see section 4.8). Signs or symptoms of cardiac failure should be periodically monitored throughout treatment with tivozanib. Management of cardiac failure events may require temporary interruption or permanent discontinuation and/or dose reduction of tivozanib therapy, plus treatment of potential underlying causes of cardiac failure, e.g. hypertension.

Haemorrhage

In clinical studies with tivozanib, haemorrhagic events have been reported (see section 4.8). Tivozanib must be used with caution in patients who are at risk for, or who have a history of bleeding. If any bleeding requires medical intervention, tivozanib should be temporarily interrupted.

Proteinuria

Proteinuria has been reported in clinical studies with tivozanib (see section 4.8). Monitoring for proteinuria before initiation of, and periodically throughout treatment is recommended. For patients who develop Grade 2 (> 1.0-3.4 g/24 hours) or Grade 3 (≥ 3.5 g/24 hours) proteinuria (National Cancer Institute Common Terminology Criteria for Adverse Events [NCI CTCAE]), the dose of tivozanib has to be reduced or the treatment temporarily interrupted. If the patient develops Grade 4 proteinuria (nephrotic syndrome) tivozanib has to be discontinued. Risk factors for proteinuria include high blood pressure.

Hepatotoxicity

In clinical studies with tivozanib, elevations of ALT, AST, and bilirubin have been reported (see section 4.8). The majority of AST and ALT elevations were not accompanied with concomitant elevations of bilirubin. AST, ALT, bilirubin, and AP should be monitored before initiation of and periodically throughout treatment with tivozanib because of the potential risk of hepatotoxicity (see section 4.2).

Tivozanib is not recommended in patients with severe hepatic impairment.

Posterior reversible encephalopathy syndrome (PRES)

In clinical studies, one case of PRES was confirmed after treatment with tivozanib (see section 4.8). PRES is a neurological disorder which can present with headache, seizure, lethargy, confusion, blindness and other visual and neurologic disturbances. Mild to severe hypertension may be present. Magnetic Resonance Imaging is necessary to confirm the diagnosis of PRES. Tivozanib must be discontinued in patients developing signs or symptoms of PRES. The safety of re-initiating tivozanib therapy in patients previously experiencing PRES is not known and tivozanib should only be used with caution in these patients.

Hand foot skin reaction (HFSR)

In clinical studies with tivozanib, hand foot skin reaction (palmar-plantar erythrodysaesthesia) has been reported. Most events in the five renal cell carcinoma monotherapy studies were CTC Grade 1 or 2 (≥ CTC Grade 3 was observed in < 2% of patients treated with tivozanib) and there were no serious events (see section 4.8). Management of patients experiencing HFSR may include topical therapies for symptomatic relief with consideration of temporary interruption and/or reduction in treatment dose or, in severe or persistent cases, permanent discontinuation of treatment.

QT interval prolongation

In clinical studies with tivozanib, QT/QTc interval prolongation has been reported (see section 4.8 and section 5.1). QT/QTc interval prolongation may lead to an increased risk for ventricular arrhythmias. It is recommended that tivozanib be used with caution in patients with a history of QT interval prolongation or other relevant pre-existing cardiac disease and those receiving other medications known to increase the QT interval. Baseline and periodic monitoring of electrocardiograms and maintenance of electrolytes (e.g. calcium, magnesium, potassium) within the normal range is recommended.

Gastrointestinal (GI) perforation/fistula

It is recommended that symptoms of GI perforation or fistula should be periodically monitored throughout treatment with tivozanib and that tivozanib should be used with caution in patients at risk for GI perforation or fistula.

Wound healing complications

For precautionary reasons, temporary interruption of tivozanib therapy is recommended in patients undergoing major surgical procedures. The decision to resume tivozanib therapy after surgery should be based on clinical judgment of adequate wound healing.

Hypothyroidism

In clinical studies with tivozanib, hypothyroidism has been reported (see section 4.8). Hypothyroidism has been observed to occur at any time during treatment with tivozanib, developing as early as within two months of treatment initiation. Risk factors for hypothyroidism include prior history of hypothyroidism and use of anti-thyroid medications. Thyroid function should be monitored before initiation of, and periodically throughout treatment with tivozanib. Hypothyroidism should be treated according to standard medical practice.

Elderly patients

Dysphonia, diarrhoea, fatigue, weight decreased, appetite decreased and hypothyroidism occurred more commonly in patients ≥ 65 years of age. Healthcare professions should be aware that elderly patients may be at increased risk of adverse reactions.

Aneurysms and artery dissections

The use of VEGF pathway inhibitors in patients with or without hypertension may promote the formation of aneurysms and/or artery dissections. Before initiating Fotivda, this risk should be carefully considered in patients with risk factors such as hypertension or history of aneurysm

Contraindication of concomitant use

Herbal preparations containing St. John's wort (Hypericum perforatum) are contraindicated. If a patient is already taking St John's wort, this should be stopped before starting tivozanib treatment. The inducing effect of St John's wort may persist for at least 2 weeks after cessation of treatment with St John's wort (see section 4.3).

Strong CYP3A4 inducers

In a clinical study in healthy volunteers, co-administration of a single 1340 microgram dose of tivozanib with a strong CYP3A4 inducer at steady-state (rifampin 600 mg once daily) decreased the average half-life of tivozanib from 121 to 54 hours which was associated with a decrease in the single dose AUC_0-∞ of 48% compared with AUC_0-∞ in the absence of rifampin. Average C_max and AUC_0-24hr were not significantly affected (8% increase and 6% decrease respectively). The clinical effects of strong CYP3A4 inducers on repeated daily dosing of tivozanib has not been studied but potentially the average time to reach steady-state and the average steady-state serum concentration of tivozanib may be reduced, due to the reduction in half-life. It is recommended that concomitant administration of tivozanib with strong CYP3A4 inducers, if used, should be undertaken with caution.

Moderate CYP3A4 inducers are not expected to have a clinically relevant effect on tivozanib exposure.

CYP3A4 inhibitors

In a clinical study in healthy volunteers, co-administration of tivozanib with a potent CYP3A4 inhibitor, ketoconazole (400 mg once daily), had no influence on tivozanib serum concentrations (C_max or AUC); therefore, tivozanib exposure is unlikely to be altered by CYP3A4 inhibitors.

Medicinal products for which intestinal absorption is restricted by BCRP

Tivozanib inhibits the transporter protein BCRP in vitro, but the clinical relevance of this finding is unknown (see section 5.2). Caution should be exercised if tivozanib is co-administered with rosuvastatin. Alternatively, a statin not subject to restriction of intestinal absorption by BCRP should be considered. Patients taking an oral BCRP substrate with a clinically-relevant efflux interaction in the gut should ensure that a suitable time window (e.g. 2 hours) is applied between administration of tivozanib and the BCRP substrate.

Contraceptives

It is currently unknown whether tivozanib may reduce the effectiveness of hormonal contraceptives, and therefore women using hormonal contraceptives should add a barrier method (see section 4.6).

Women of childbearing potential/Contraception in males and females

Women of childbearing potential should avoid becoming pregnant while on tivozanib. Female partners of male patients taking tivozanib should also avoid pregnancy. Effective methods of contraception should be used by male and female patients and their partners during therapy, and for at least one month after completing therapy. It is currently unknown whether tivozanib may reduce the effectiveness of hormonal contraceptives and therefore women using hormonal contraceptives should add a barrier method.

Pregnancy

There are no data from the use of tivozanib in pregnant women. Studies in animals have shown reproductive toxicity (see section 5.3).

Tivozanib should not be used during pregnancy. If tivozanib is used during pregnancy, or if the patient becomes pregnant while receiving tivozanib, the potential hazard to the foetus must be explained to the patient.

Breast-feeding

It is unknown whether tivozanib is excreted in human milk, but the potential exists. Because of the potential for tivozanib-mediated adverse reactions in breastfed infants, women should not breast-feed while taking tivozanib.

Fertility

Animal studies indicate that male and female fertility may be affected by treatment with tivozanib (see section 5.3).

Tivozanib may have a minor influence on the ability to drive and use machines. Patients should be advised to be cautious when driving or using machines if they experience asthenia, fatigue, and/or dizziness during treatment with tivozanib (see section 4.8).

Summary of the safety profile

Pooled data of 674 patients with advanced RCC who continued to receive tivozanib as their initial on trial therapy in the five core RCC monotherapy studies have been evaluated in the overall assessment of safety and tolerability of tivozanib.

The most important serious adverse reaction is hypertension.

The most common adverse reactions of any grade include hypertension (47.6%), dysphonia (26.9%), fatigue (25.8%) and diarrhoea (25.5%).

In the five core RCC monotherapy studies tivozanib was discontinued in a total of 20 patients (3%) owing to adverse reactions, most commonly due to hypertension (0.4%), persistent severe hypertension (0.3%), or acute myocardial infarction (0.3%). The most frequent adverse reactions leading to tivozanib dose reduction/ interruption were hypertension (4.7%), diarrhoea (3.1%), fatigue (1.8%).

In patients receiving tivozanib as initial therapy, there were three adverse reactions with outcome death; one was uncontrolled hypertension in the setting of a suspected overdose (see section 4.9) and two were reported simply as death.

Tabulated summary of adverse reactions

Adverse reactions occurring in patients who continued to receive tivozanib as their initial on trial therapy in the five RCC monotherapy studies were pooled and are listed below by MedDRA body system organ class (SOC) and frequency. Frequencies are defined as follows: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100), rare (≥ 1/10,000 to < 1/1,000) and not known (cannot be estimated from available data).

Description of selected adverse reactions

Hypertension

Hypertension was reported as an adverse reaction in 47.6% of patients receiving tivozanib as initial therapy; in 23.0% the hypertension was CTC ≥ Grade 3. Persistent severe hypertension ('hypertensive crisis') was an adverse reaction in 1.0%, CTC Grade 3 or higher in 0.9%. One patient died as a result of uncontrolled hypertension in the setting of a suspected overdose.

Posterior Reversible Encephalopathy Syndrome (PRES)

PRES (also known as reversible posterior leukoencephalopathy syndrome (RPLS)) was confirmed in one non-RCC patient after approximately 8 weeks on tivozanib. PRES is a neurological disorder that may present with headache, seizure, lethargy, confusion, blindness and other visual and neurologic disturbances. Mild to severe hypertension may be present (see section 4.4).

Venous thromboembolism

Pulmonary embolism was reported in patients (0.7%) receiving tivozanib as initial therapy in the five core RCC monotherapy studies, with the majority CTC Grade ≥ 3 (see section 4.4). Deep vein thrombosis was also reported in two patients (0.3%) and was CTC Grade ≥ 3 in one patient (0.1%) receiving initial tivozanib therapy.

Arterial thromboembolic events

Arterial thromboembolic adverse reactions in the patients receiving tivozanib as initial therapy were ischaemic stroke (1.0%), myocardial infarction (0.7%), transient ischaemic attack (0.7%) and acute myocardial infarction (0.4%), the majority of which were at least CTC Grade 3, plus iliac artery thrombosis (0.1%). There were no deaths due to arterial thromboembolic adverse reactions in those receiving tivozanib as initial therapy but a myocardial infarction in a patient receiving second-line tivozanib had a fatal outcome.

Cardiac failure

Pulmonary oedema was reported in two patients (0.3%) receiving tivozanib as initial therapy in the five core RCC monotherapy studies. Both events were CTC Grade 3 (see section 4.4).

QT/QTc prolongation

QT prolongation was reported in two patients (CTC Grade 2 and Grade 3) in the tivozanib cardiac safety study, neither reaction was considered serious (see section 4.4 and section 5.1).

Hypothyroidism

Hypothyroidism was reported as an adverse reaction for 5.6% of patients during initial therapy and was CTC Grade 2 or lower in all cases. It was reported as serious in one patient.

Haemorrhage

Haemorrhage adverse reactions were reported in the core monotherapy studies during initial treatment (see section 4.4).

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

Two patients received excessive doses of tivozanib during the monotherapy studies. A patient with a history of hypertension experienced aggravated uncontrolled hypertension that was fatal after taking 3 doses of 1340 microgram tivozanib in one day (total 4020 microgram). No adverse reaction was experienced by the second patient who took 2 doses of 1340 microgram tivozanib in one day (total 2680 microgram).

Blood pressure should be well controlled prior to initiating tivozanib and patients should be monitored for hypertension during treatment (see section 4.4).

In cases of suspected overdose, tivozanib should be discontinued and the patient monitored for hypertension and treated as needed with standard anti- hypertensive therapy.

There is no specific treatment or antidote for tivozanib overdose.

Pharmacotherapeutic group: antineoplastic agents, protein-kinase inhibitors, ATC code: L01EK03

Mechanism of action

Tivozanib potently and selectively blocks all 3 vascular endothelial growth factor receptors (VEGFR) and has been shown to block various VEGF-induced biochemical and biologic responses in vitro, including VEGF-ligand-induced phosphorylation of all three VEGFR 1, 2 and 3, and proliferation of human endothelial cells. The next most potently inhibited kinase is c-kit which is 8-fold less sensitive to inhibition by tivozanib compared to VEGFR 1, 2 and 3. VEGF is a potent mitogenic factor that plays a central role in angiogenesis and vascular permeability of tumour tissues. By blocking VEGF-induced VEGFR activation, tivozanib inhibits angiogenesis and vascular permeability in tumour tissues, leading to inhibition of tumour growth in vivo.

Clinical efficacy and safety

The efficacy of tivozanib in the treatment of advanced RCC was studied in the following randomised clinical study.

Study AV-951-09-301

This controlled clinical study was a Phase 3 multi-centre, open-label, international, randomised study comparing tivozanib with sorafenib in patients with advanced RCC. Five hundred and seventeen (517) patients with recurrent or metastatic RCC with a clear cell component were randomised (1:1) to receive either tivozanib 1340 microgram once daily on a schedule of 3 weeks on treatment followed by 1 week off (schedule 3/1) or sorafenib 400 mg twice a day. The study included patients who had all undergone prior nephrectomy, and who had received either no prior therapy or no more than one prior systemic therapy in the metastatic setting (immunotherapy/chemotherapy); prior treatment with VEGF or mechanistic Target of Rapamycin (mTOR) targeted therapy was not allowed. Cross-over to the tivozanib arm was permitted upon Response Evaluation Criteria In Solid Tumours (RECIST)-defined progression on sorafenib according to the protocol of a separate extension study.

The primary endpoint of the study was progression-free survival (PFS) by blinded independent radiology review; key secondary endpoints included overall survival (OS) and objective response rate (ORR) by independent radiology review.

The intent-to-treat (ITT) population included 517 patients, 260 randomised to tivozanib and 257 randomised to sorafenib. The baseline demographic and disease characteristics were generally well balanced across the tivozanib and sorafenib arms with regard to age (mean age 58.2 vs 58.4 years respectively), gender (71.2% vs 73.5% male respectively), race (95.8% vs 96.9% white respectively), geographic region (88.1% vs 88.7% from Central/Eastern Europe respectively) and prior treatment for metastatic RCC (69.6% vs 70.8% treatment naï ve respectively). For the 30% of patients receiving prior treatment, the predominant therapy was interferon alpha as monotherapy which was received by 75 patients in the tivozanib arm and 62 patients in the sorafenib arm.

Tivozanib showed a statistically significant improvement in PFS and ORR over sorafenib by independent radiology review (Table 2 and Figure 1).

Table 2: Efficacy analysis by independent radiology review (ITT population)

^a Hazard ratio for tivozanib arm vs. sorafenib arm, based on stratified Cox proportional hazards model. Stratification factors are number of prior treatments (0 or 1) and number of metastatic sites/organs involved (1 or ≥ 2). Assuming proportional hazards, a hazard ratio less than 1 indicates a reduction in hazard rate in favour of tivozanib;

^b p-value based on stratified log-rank test. Stratification factors are number of prior treatments (0 or 1) and number of metastatic sites/organs involved (1 or ≥ 2);

^c p-value based on stratified Cochran-Mantel-Haenszel (CMH) statistic. Stratification factors are number of prior treatments (0 or 1) and number of metastatic sites/organs involved (1 or ≥ 2);

^d Hazard ratio for tivozanib arm vs. sorafenib arm subgroup analyses, based on unstratified Cox proportional hazards model. Assuming proportional hazards, a hazard ratio less than 1 indicates a reduction in hazard rate in favour of tivozanib;

^e p-value for subgroup analyses based on unstratified log-rank test.

OS was a key secondary endpoint in the pivotal study and the analysis included data from all randomized patients, including those who progressed on sorafenib and crossed over to receive tivozanib as part of the extension study. In the ITT population there was a small numerical difference between the two arms in terms of overall survival. median OS was 28.2 months (95% CI 22.5, 33.0) in the tivozanib arm compared to 30.8 months (95% CI 28.4, 33.3) in the sorafenib arm (HR=1.147, p=0.276).

Elderly patients

In a controlled clinical study (AV-951-09-301), in which 25% of patients receiving tivozanib were ≥ 65 years of age, no overall differences was observed in efficacy between elderly and younger patients (see section 4.2). In the core RCC studies some adverse reaction occurred more commonly in the elderly (see section 4.4).

Pharmacodynamic effects

In a cardiac safety study of 50 patients with advanced solid tumours treated with tivozanib at 1340 microgram daily for 21 days, the mean change from baseline in QTcF was 6.8 ms on day 21 of dosing. The maximum change in QTcF from baseline was 9.3 ms (90% CI: 5, 13.6), which occurred 2.5 hours after dosing on Day 21. The central tendency change for all measured days and across all time points was 2.2 ms. No subjects had a new > 500 ms change in QTcF; 2 patients (4%) had QTcF values > 480 ms. One subject (2%) had a > 60 ms change from baseline in QTcF and 6 subjects (12%) had a 30 ms to 60 ms change from baseline (see section 4.4 and section 4.8).

Paediatric population

The European Medicines Agency has waived the obligation to submit the results of studies with tivozanib in all subsets of the paediatric population in advanced renal cell carcinoma (see section 4.2 for information on paediatric use).

Absorption

Following oral administration of tivozanib, peak serum levels are achieved after approximately 2 to 24 hours. After a single 1340 microgram dose, mean C_max was 10.2 to 25.2 ng/mL across healthy subject and patient studies. Single dose AUC_0-inf for healthy volunteers dosed with 1340 microgram tivozanib was 1,950 to 2,491 ng.hr/mL. After once daily dosing of 1340 microgram tivozanib for 21 or 28 days in RCC patients, C_max was 67.5 to 94.3 ng/mL and AUC_0-24 was 1,180 to 1,641 ng.hr/mL. Exposure is dose proportional between 890 and 1340 microgram and dose related over the wider range of 450 mg and 1790 microgram. Accumulation at steady-state is approximately 6- to 7- fold the exposure observed at single-dose levels. Clearance is similar between acute and chronic dosing indicating no time dependent changes in PK.

When tivozanib was evaluated in a food effect study in healthy subjects, a high fat meal decreased the peak serum concentrations (C_max) by 23.4% compared to the fasted state. There was no effect of food on the overall exposure (AUC). Based on these data, tivozanib can be dosed with or without food (see section 4.2).

Distribution

In vitro protein binding studies have shown that tivozanib is > 99% bound to plasma proteins. No concentration dependence of plasma protein binding was observed over the range of 0.1 to 5 µ mol/L tivozanib. Albumin is the major tivozanib binding component in human plasma. In vitro studies have shown that tivozanib is neither a substrate nor an inhibitor of the multidrug efflux pump, P-glycoprotein. In vitro studies suggest that tivozanib is an inhibitor of intestinal BCRP.

Biotransformation

In vitro metabolism studies have shown that CYP3A4 and CYP1A1 are capable of metabolising tivozanib. Unchanged tivozanib is the major circulating form of the molecule, and there were no major metabolites detected in serum at exposure equal to or greater than 10% of the total radioactivity exposure. As CYP1A1 is primarily expressed in extrahepatic tissues such as the lung and intestine, it was considered unlikely that this isoform would be extensively involved in hepatic metabolism.

In vitro studies have shown that metabolites of tivozanib can undergo UGT mediated biotransformation via the UGT1A1, UGT1A3, UGT1A7, UGT1A8, UGT1A9, and UGT1A10 pathways. Direct N-glucoronidation of tivozanib was a minor pathway of metabolism in vitro.

Elimination

After chronic dosing of tivozanib in RCC patients for 21 days followed by 7 days without administration of tivozanib, tivozanib C_min is approximately 16.0 to 30.9 ng/mL.

In studies that evaluated the terminal elimination phase, tivozanib had a mean t_½ of 4.5 - 5.1 days. After a single dose oral dose of [¹⁴C] tivozanib, approximately 79% of the radioactivity was recovered in the faeces and approximately 12% was found in the urine as metabolites. There was no unchanged tivozanib recovered in the urine indicating that tivozanib does not undergo renal excretion. [¹⁴C] Tivozanib was the predominant drug-related material in faeces. There were no [¹⁴C]-containing metabolites present in faeces at greater than 10% of the dose.

Special populations

Age, gender and race

Based on the population pharmacokinetic analysis, there is no clinically relevant effect of age, gender or race on the pharmacokinetics of tivozanib.

Hepatic impairment

Results from a single dose study to evaluate the pharmacokinetics, safety and tolerability of tivozanib in subjects with hepatic impairment show that across the entire measurement period, tivozanib was eliminated more slowly in subjects with moderate (Child-Pugh Class B) or severe (Child-Pugh Class C) hepatic impairment. Tivozanib exposure was increased in patients with severe hepatic impairment (mean AUC_0-∞ by 4.0-fold) and in patients with moderate hepatic impairment (mean AUC_0-∞ by 2.6-fold). No significant increase in exposure was observed in patients with mild (Child-Pugh Class A) hepatic impairment (mean AUC_0-∞ by 1.2-fold). Tivozanib should be used with caution in patients with moderate hepatic impairment and the dose reduced to one 1340 microgram capsule every other day. Tivozanib should not be used in patients with severe hepatic impairment (see section 4.2 and section 4.4).

Renal impairment

Clinical studies with tivozanib were conducted in RCC patients with serum creatinine concentration ≤ 2 times the upper limit of normal, including those who may have had a prior nephrectomy. Although the impact of further impairment of renal function on the overall disposition of tivozanib is unknown, a clinical study has shown that no unchanged tivozanib is excreted in the urine indicating that tivozanib does not undergo renal excretion. According to the population pharmacokinetic analysis of tivozanib exposure, no dose adjustment is required in patients with mild or moderate renal impairment. Experience of tivozanib use in patients with severe renal impairment is limited and caution is advised.

CYP and UGT in vitro studies

In vitro studies with tivozanib indicate that it is not a CYP enzyme inducer. In vitro studies conducted in human liver microsomes and hepatocytes evaluating the activity of CYP1A2, CYP2B6, CYP2A6, CYP2C8, CYP2C9, CYP2C19, CYP2D6 and CYP3A4 suggested that tivozanib is a weak inhibitor of CYP2B6 and CYP2C8. Based on the in vitro IC₅₀ and in vivo unbound C_max, tivozanib was unlikely to interact in a clinically relevant manner with active substances that are metabolised by these enzyme pathways.

Studies conducted in vitro have shown that tivozanib is not a potent inhibitor of UGT (UDP-glucuronosyltransferase) metabolic activities and clinically relevant drug-drug interactions are unlikely with medicinal products metabolised by these pathways.

Transporter in vitro studies

In vitro studies have shown that tivozanib is neither a substrate nor inhibitor of the transporter proteins MDR1 (P-gp), OCT1, OATP1B1, OATP1B3 and BSEP. Furthermore, tivozanib was not an in vitro inhibitor of OAT1, OAT3, OCT2, MATE1 and MATE2-K or substrate of MRP2 and BCRP.

Tivozanib inhibits the transporter protein BCRP in vitro, at concentrations that are likely to restrict the effect to intestinal BCRP activity in vivo.

Adverse reactions not observed in clinical studies, but seen in animals at exposure levels similar to clinical exposure levels and with possible relevance to clinical use were as follows.

In repeat-dose toxicity studies in rats, abnormalities were noted in growing incisors (thin brittle teeth, tooth loss, malocclusions) at doses approximately 2-fold greater than the calculated human equivalent dose and growth plate hypertrophy was observed at doses approximately 0.7- to 7-fold greater than the calculated human equivalent dose. Tivozanib was shown to cause growth plate hypertrophy, absence of active corpora lutea and no maturing follicles in cynomolgus monkeys at dose levels that produced exposures equivalent to those seen at the recommended clinical dose.

Reproduction, mutagenesis, impairment of fertility

Tivozanib may impair human fertility. In nonclinical studies assessing mating and fertility parameters in male rats, doses > 2-fold higher than the recommended clinical dose, produced increased epididymis and testis weights associated with infertility. Increased testis weights were observed at a dose 7-fold higher than the recommended clinical dose. In female rats, an increase in non-viable foetuses was noted at a dose 0.7-fold the recommended clinical dose, while dose levels ≥ 2 fold the recommended clinical dose produced infertility.

Tivozanib was shown to be teratogenic, embryotoxic and foetotoxic in pregnant rats at dose levels 5 times lower than the recommended clinical dose (based on a 60 kg human). Studies in pregnant rabbits showed no effect on maternal health or embryo foetal development at doses approximately 0.6 times the human exposure at the recommended dose.
