近日，勃林格殷格翰（Boehringer Ingelheim）罕见病药物Ofev（nintedanib）口服药获欧盟委员会（EC）批准用于特发性肺纤维化（IPF）的治疗。
在美国，Ofev（nintedanib）于2014年10月15日获FDA批准，同一天获批的还有另一款药物Esbriet（比非尼酮），Esbriet和Ofev的上市，结束了美国IPF患者群体无药可用的局面。Esbriet由InterMune开发，罗氏于2014年8月耗资83亿美元收购InterMune后将该药收入囊中，该笔交易在很大程度上就是因为罗氏看中了Esbriet在特发性肺纤维化（IPF）市场中的前景。
在欧盟，Esbriet于2011年获欧盟委员会（EC）批准。此次Ofev拿下欧盟批文，也标志着，在欧洲市场，勃林格将与罗氏一决雌雄！
特发性肺纤维化（IPF）是一种罕见的肺部疾病，根据肺纤维化联盟（CPF）数据，每年IPF死亡病例达40000例。
Ofev在欧盟的获批，是基于III期INPULSIS项目的数据，该项目包括2项III期研究（INPULSIS-1和INPULSIS-2），涉及来自24个国家的1066例特发性肺纤维化（IPF）患者，研究结果显示，在广泛类型IPF群体中，nintedanib显著延缓了病情的恶化，并显著降低了急性发作风险，2项研究均达到了主要终点。
Nintedanib是一种口服三联血管激酶抑制剂，可同时阻断3种生长因子受体：血管内皮生长因子受体（VEGFR 1-3）、血小板源性生长因子受体（PDGFR α和β）、成纤维细胞生长因子受体（FGFR 1-3）。所有这3种受体在血管生成和肿瘤生长过程中均发挥着重要作用。这些受体的阻断，可能导致血管生成的抑制，而血管生成在肿瘤生长中起着关键作用。
目前，勃林格殷格翰正在多种实体瘤中评价nintedanib，其中晚期非小细胞肺癌（NSCLC）、结直肠癌、卵巢癌已处于III期临床，间皮瘤、肾癌（肾细胞癌）、肝癌（肝细胞癌）处于II期临床。

2. Qualitative and quantitative composition
One capsule contains 150 mg nintedanib (as esilate)
Excipient(s) with known effect:
Each capsule contains 1.8 mg of soya lecithin.
For the full list of excipients, see section 6.1.
3. Pharmaceutical form
Soft capsule.
Ofev 150 mg soft capsules are brown-coloured, opaque, oblong soft-gelatin capsules imprinted on one side in black with the Boehringer Ingelheim company symbol and “150”.
4. Clinical particulars
4.1 Therapeutic indications
Ofev is indicated in adults for the treatment of Idiopathic Pulmonary Fibrosis (IPF).
4.2 Posology and method of administration
Treatment with Ofev should be initiated by physicians experienced in the diagnosis and treatment of IPF.
Posology
The recommended dose is 150 mg nintedanib twice daily administered approximately 12 hours apart.
If a dose is missed, administration should resume at the next scheduled time at the recommended dose. If a dose is missed the patient should not take an additional dose. The recommended maximum daily dose of 300 mg should not be exceeded.
Dose adjustments
In addition to symptomatic treatment if applicable, the management of adverse reactions to Ofev (see sections 4.4 and 4.8) could include dose reduction and temporary interruption until the specific adverse reaction has resolved to levels that allow continuation of therapy. Ofev treatment may be resumed at the full dose (150 mg twice daily) or a reduced dose (100 mg twice daily). If a patient does not tolerate 100 mg twice daily, treatment with Ofev should be discontinued.
In case of interruptions due to aspartate aminotransferase (AST) or alanine aminotransferase (ALT) elevations > 3x upper limit of normal (ULN), once transaminases have returned to baseline values, treatment with Ofev may be reintroduced at a reduced dose (100 mg twice daily) which subsequently may be increased to the full dose (150 mg twice daily) (see sections 4.4 and 4.8).
Special populations
Elderly patients (≥ 65 years)
No overall differences in safety and efficacy were observed for elderly patients. No a-priori dose adjustment is required on the basis of a patient's age. Patients ≥75 years may be more likely to require dose reduction to manage adverse effects (see section 5.2).
Renal impairment
Less than 1% of a single dose of nintedanib is excreted via the kidney (see section 5.2). Adjustment of the starting dose in patients with mild to moderate renal impairment is not required. The safety, efficacy, and pharmacokinetics of nintedanib have not been studied in patients with severe renal impairment (<30 ml/min creatinine clearance).
Hepatic impairment
Nintedanib is predominantly eliminated via biliary/faecal excretion (> 90%; see section 5.2). No adjustment of the starting dose is needed for patients with mild hepatic impairment based on clinical data (Child Pugh A; see section 4.4). The safety and efficacy of nintedanib have not been investigated in patients with hepatic impairment classified as Child Pugh B and C. Therefore, treatment of patients with moderate (Child Pugh B) and severe (Child Pugh C) hepatic impairment with Ofev is not recommended.
Paediatric population
The safety and efficacy of Ofev in children aged 0-18 years have not been established. No data are available.
Method of administration
Ofev is for oral use. The capsules should be taken with food, swallowed whole with water, and should not be chewed or crushed.
4.3 Contraindications
Hypersensitivity to nintedanib, to peanut or soya, or to any of the excipients listed in section 6.1.
4.4 Special warnings and precautions for use
Gastrointestinal disorders
Diarrhoea
In the INPULSIS trials (see section 5.1), diarrhoea was the most frequent gastro-intestinal adverse reaction reported in 62.4% versus 18.4% of patients treated with Ofev and placebo, respectively (see section 4.8). In most patients the adverse reaction was of mild to moderate intensity and occurred within the first 3 months of treatment. Diarrhoea led to dose reduction in 10.7% of the patients and to discontinuation of nintedanib in 4.4% of the patients.
Diarrhoea should be treated at first signs with adequate hydration and anti-diarrhoeal medicinal products, e.g. loperamide, and may require treatment interruption. Ofev treatment may be resumed at a reduced dose (100 mg twice daily) or at the full dose (150 mg twice daily). In case of persisting severe diarrhoea despite symptomatic treatment, therapy with Ofev should be discontinued.
Nausea and vomiting
Nausea and vomiting were frequently reported gastrointestinal adverse reactions (see section 4.8). In most patients with nausea and vomiting, the event was of mild to moderate intensity. Nausea led to discontinuation of nintedanib in 2.0% of patients. Vomiting led to discontinuation in 0.8% of the patients.
If symptoms persist despite appropriate supportive care (including anti-emetic therapy), dose reduction or treatment interruption may be required. The treatment may be resumed at a reduced dose (100 mg twice daily) or at the full dose (150 mg twice daily). In case of persisting severe symptoms therapy with Ofev should be discontinued.
Hepatic function
The safety and efficacy of Ofev has not been studied in patients with moderate (Child Pugh B) or severe (Child Pugh C) hepatic impairment. Therefore treatment with Ofev is not recommended in such patients (see sections 4.2).
Administration of nintedanib was associated with elevations of liver enzymes (ALT, AST, alkaline phosphatase (ALKP), gamma-glutamyl-transferase (GGT)) with a potentially higher risk for female patients. Transaminase increases were reversible upon dose reduction or interruption. Administration of nintedanib was also associated with elevations of bilirubin. Hepatic transaminase and bilirubin levels should be investigated before the initiation of treatment with Ofev, and periodically thereafter (e.g. at each patient visit) or as clinically indicated. If transaminase (AST or ALT) elevations > 3x ULN are measured, dose reduction or interruption of the therapy with Ofev is recommended and the patient should be monitored closely. Once transaminases have returned to baseline values, treatment with Ofev may be resumed at the full dose (150 mg twice daily) or reintroduced at a reduced dose (100 mg twice daily) which subsequently may be increased to the full dose (see section 4.2). If any liver test elevations are associated with clinical signs or symptoms of liver injury, e.g. jaundice, treatment with Ofev should be permanently discontinued. Alternative causes of the liver enzyme elevations should be investigated.
Haemorrhage
Vascular endothelial growth factor receptor (VEGFR) inhibition might be associated with an increased risk of bleeding. In the INPULSIS trials with Ofev, the frequency of patients who experienced bleeding AEs was slightly higher in the Ofev arm (10.3%) than in the placebo arm (7.8%). Non-serious epistaxis was the most frequent bleeding event. Serious bleeding events occurred with low and similar frequencies in the 2 treatment groups (placebo: 1.4%; Ofev: 1.3%).
Patients at known risk for bleeding including patients with inherited predisposition to bleeding or patients receiving a full dose of anticoagulative treatment were not included in the INPULSIS studies. Therefore these patients should only be treated with Ofev if the anticipated benefit outweighs the potential risk.
Arterial thromboembolic events
Patients with a recent history of myocardial infarction or stroke were excluded from the INPULSIS trials. Arterial thromboembolic events were infrequently reported: in 0.7% of patients in the placebo and 2.5% in the nintedanib treated group. While adverse events reflecting ischaemic heart disease were balanced between the nintedanib and placebo groups, a higher percentage of patients experienced myocardial infarctions in the nintedanib group (1.6%) compared to the placebo group (0.5%). Caution should be used when treating patients at higher cardiovascular risk including known coronary artery disease. Treatment interruption should be considered in patients who develop signs or symptoms of acute myocardial ischemia.
Venous thromboembolism
In the INPULSIS trials no increased risk of venous thromboembolism was observed in nintedanib treated patients. Due to the mechanism of action of nintedanib patients might have an increased risk of thromboembolic events.
Gastrointestinal perforations
In the INPULSIS trials no increased risk of gastrointestinal perforation was observed in nintedanib treated patients. Due to the mechanism of action of nintedanib patients might have an increased risk of gastrointestinal perforation. Particular caution should be exercised when treating patients with previous abdominal surgery. Ofev should only be initiated at least 4 weeks after abdominal surgery. Therapy with Ofev should be permanently discontinued in patients who develop gastrointestinal perforation.
Hypertension
Administration of Ofev may increase blood pressure. Systemic blood pressure should be measured periodically and as clinically indicated.
Wound healing complication
No increased frequency of impaired wound healing was observed in the INPULSIS trials. Based on the mechanism of action nintedanib may impair wound healing. No dedicated studies investigating the effect of nintedanib on wound healing were performed. Treatment with Ofev should therefore only be initiated or - in case of perioperative interruption - resumed based on clinical judgement of adequate wound healing.
Co-administration with pirfenidone
Concomitant treatment of nintedanib with pirfenidone was investigated in a parallel group design study in Japanese patients with IPF. Twenty four patients were treated for 28 days with 150 mg nintedanib twice daily (13 patients received nintedanib on top of chronic treatment with standard doses of pirfenidone; 11 patients received nintedanib alone). Due to the short duration of concomitant exposure and low number of patients the benefit/risk of the co-administration with pirfenidone has not been established.
Effect on QT interval
No evidence of QT prolongation was observed for nintedanib in the clinical trial programme (Section 5.1). As some other tyrosine kinase inhibitors are known to exert an effect on QT, caution should be exercised when administered nintedanib in patients who may develop QTc prolongation.
Allergic reaction
Dietary soya products are known to cause allergic reactions including severe anaphylaxis in persons with soya allergy. Patients with known allergy to peanut protein carry an enhanced risk for severe reactions to soya preparations.
4.5 Interaction with other medicinal products and other forms of interaction
P-glycoprotein (P-gp)
Nintedanib is a substrate of P-gp (see section 5.2). Co-administration with the potent P-gp inhibitor ketoconazole increased exposure to nintedanib 1.61-fold based on AUC and 1.83-fold based on Cmax in a dedicated drug-drug interaction study. In a drug-drug interaction study with the potent P-gp inducer rifampicin, exposure to nintedanib decreased to 50.3% based on AUC and to 60.3% based on Cmax upon co-administration with rifampicin compared to administration of nintedanib alone. If co-administered with Ofev, potent P-gp inhibitors (e.g. ketoconazole, erythromycin or cyclosporine) may increase exposure to nintedanib. In such cases, patients should be monitored closely for tolerability of nintedanib. Management of side effects may require interruption, dose reduction, or discontinuation of therapy with Ofev (see section 4.2).
Potent P-gp inducers (e.g. rifampicin, carbamazepine, phenytoin, and St. John's Wort) may decrease exposure to nintedanib. Selection of an alternate concomitant medicinal product with no or minimal P-gp induction potential should be considered.
Cytochrome (CYP)-enzymes
Only a minor extent of the biotransformation of nintedanib consisted of CYP pathways. Nintedanib and its metabolites, the free acid moiety BIBF 1202 and its glucuronide BIBF 1202 glucuronide, did not inhibit or induce CYP enzymes in preclinical studies (see section 5.2). The likelihood of drug-drug interactions with nintedanib based on CYP metabolism is therefore considered to be low.
Co-administration with other medicinal products
The potential for interactions of nintedanib with hormonal contraceptives was not explored.
4.6 Fertility, pregnancy and lactation
Women of childbearing potential / Contraception
Nintedanib may cause foetal harm in humans (see section 5.3). Women of childbearing potential should be advised to avoid becoming pregnant while receiving treatment with Ofev. They should be advised to use adequate contraception during and at least 3 months after the last dose of Ofev. Since the effect of nintedanib on the metabolism and efficacy of hormonal contraceptives has not been investigated, barrier methods should be applied as a second form of contraception, to avoid pregnancy.
Pregnancy
There is no information on the use of Ofev in pregnant women, but pre-clinical studies in animals have shown reproductive toxicity of this active substance (see section 5.3). As nintedanib may cause foetal harm also in humans, it must not be used during pregnancy.
Female patients should be advised to notify their doctor or pharmacist if they become pregnant during therapy with Ofev.
If the patient becomes pregnant while receiving Ofev, she should be apprised of the potential hazard to the foetus. Termination of the treatment with Ofev should be considered.
Breast-feeding
There is no information on the excretion of nintedanib and its metabolites in human milk.
Pre-clinical studies showed that small amounts of nintedanib and its metabolites (≤ 0.5% of the administered dose) were secreted into milk of lactating rats. A risk to the newborns/infants cannot be excluded. Breast-feeding should be discontinued during treatment with Ofev.
Fertility
Based on preclinical investigations there is no evidence for impairment of male fertility (see section 5.3). From subchronic and chronic toxicity studies, there is no evidence that female fertility in rats is impaired at a systemic exposure level comparable with that at the maximum recommended human dose (MRHD) of 150 mg twice daily (see section 5.3).
4.7 Effects on ability to drive and use machines
Ofev has minor influence on the ability to drive and use machines. Patients should be advised to be cautious when driving or using machines during treatment with Ofev.
4.8 Undesirable effects
Summary of the safety profile
Nintedanib has been studied in clinical trials of 1,529 patients suffering from IPF. The safety data provided in the following are based on the two Phase III, randomised, double-blind, placebo-controlled studies in 1,061 patients comparing treatment with nintedanib 150 mg twice daily to placebo for 52 weeks (INPULSIS-1 and INPULSIS-2).
The most frequently reported adverse reactions associated with the use of nintedanib included diarrhoea, nausea and vomiting, abdominal pain, decreased appetite, weight decreased and hepatic enzyme increased.
For the management of selected adverse reactions please also refer to section 4.4.
Tabulated list of adverse reactions
The below table provides a summary of the adverse reactions by MedDRA System Organ Class (SOC) and frequency category.
Table 1 summarizes the frequencies of adverse drug reactions (ADRs) that were reported in the nintedanib group (638 patients) pooled from the two placebo-controlled Phase III clinical trials of 52 weeks duration.
Frequency categories are defined using the following convention:
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), very rare (< 1/10,000), not known (cannot be estimated from the available data).
Within each frequency grouping adverse reactions are presented in order of decreasing seriousness.

Description of selected adverse reactions
Diarrhoea
Diarrhoea was reported in 62.4% of patients treated with nintedanib. The event was reported to be of severe intensity in 3.3% of nintedanib treated patients. More than two thirds of patients experiencing diarrhoea reported its first onset already during the first three months of treatment. Diarrhoea led to permanent treatment discontinuation in 4.4% of patients; otherwise the events were managed by anti-diarrhoeal therapy, dose reduction or treatment interruption (see section 4.4).
Hepatic enzyme increased
Liver enzyme elevations (see section 4.4) were reported in 13.6% of nintedanib treated patients. Elevations of liver enzymes were reversible and not associated with clinically manifest liver disease.
For further information about special populations, recommended measures and dosing adjustments in case of diarrhoea and hepatic enzyme increased, refer additionally to sections 4.4 and 4.2, respectively.

4.9 Overdose
There is no specific antidote or treatment for Ofev overdose. Two patients in the oncology programme had an overdose of maximum 600 mg twice daily up to eight days. Observed adverse reactions were consistent with the known safety profile of nintedanib, i.e. increased liver enzymes and gastrointestinal symptoms. Both patients recovered from these adverse reactions. In the INPULSIS trials, one patient was inadvertently exposed to a dose of 600 mg daily for a total of 21 days. A non-serious adverse event (nasopharyngitis) occurred and resolved during the period of incorrect dosing, with no onset of other reported events. In case of overdose, treatment should be interrupted and general supportive measures initiated as appropriate.
5. Pharmacological properties
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antineoplastic agents, protein kinase inhibitors, ATC code: L01XE31
Mechanism of action
Nintedanib is a small molecule tyrosine kinase inhibitor including the receptors platelet-derived growth factor receptor (PDGFR) α and β, fibroblast growth factor receptor (FGFR) 1-3, and VEGFR 1-3. Nintedanib binds competitively to the adenosine triphosphate (ATP) binding pocket of these receptors and blocks the intracellular signalling. In addition nintedanib inhibits Flt-3 (Fms-like tyrosine-protein kinase), Lck (lymphocyte-specific tyrosine-protein kinase), Lyn (tyrosine-protein kinase lyn) and Src (proto-oncogene tyrosine-protein kinase src) kinases.
Pharmacodynamic effects
Nintedanib inhibits the activation of FGFR and PDGFR signalling cascades which are critically involved in proliferation, migration and differentiation of lung fibroblasts/myofibroblasts, the hallmark cells in the pathology of idiopathic pulmonary fibrosis. The potential impact of VEGFR inhibition by nintedanib and the anti-angiogenic activity of nintedanib on IPF pathology are currently not fully elucidated. In preclinical disease models of lung fibrosis nintedanib exerts potent anti-fibrotic and anti-inflammatory activity. Nintedanib inhibits proliferation, migration and fibroblast to myofibroblast transformation of human lung fibroblasts from patients with IPF.
Clinical efficacy and safety
The clinical efficacy of nintedanib has been studied in patients with IPF in two phase III, randomised, double-blind, placebo-controlled studies with identical design (INPULSIS-1 (1199.32) and INPULSIS-2 (1199.34)). Patients with FVC baseline < 50% predicted or carbon monoxide diffusing capacity (DLCO, corrected for haemoglobin) < 30% predicted at baseline were excluded from the trials. Patients were randomized in a 3:2 ratio to treatment with Ofev 150 mg or placebo twice daily for 52 weeks.
The primary endpoint was the annual rate of decline in Forced Vital Capacity (FVC). The key secondary endpoints were change from baseline in Saint George's Respiratory Questionnaire (SGRQ) total score at 52 weeks and time to first acute IPF exacerbation.
Annual rate of decline in FVC
The annual rate of decline of FVC (in mL) was significantly reduced in patients receiving nintedanib compared to patients receiving placebo. The treatment effect was consistent in both trials. See Table 2 for individual and pooled study results.

¹ Estimated based on a random coefficient regression model.
CI: confidence interval
The robustness of the effect of nintedanib in reducing the annual rate of decline in FVC was confirmed in all pre-specified sensitivity analyses. In patients with missing data, the primary analysis assumes that the decline in FVC after the last observed value would be similar to the decline in other patients in the same treatment group. In a sensitivity analysis which assumed that in patients with missing data at week 52 the FVC decline after the last observed value would be the same as in all placebo patients, the adjusted difference in the annual rate of decline between nintedanib and placebo was 113.9 mL/year (95% CI 69.2, 158.5) in INPULSIS-1 and 83.3 mL/year (95% CI 37.6, 129.0) in INPULSIS-2.
In addition, similar effects were observed on other lung function endpoints e.g. change from baseline in FVC at week 52 and FVC responder analyses providing further substantiation of the effects of nintedanib on slowing disease progression. See Figure 1 for the evolution of change from baseline over time in both treatment groups, based on the pooled analysis of studies INPULSIS-1 and INPULSIS-2.

FVC responder analysis
In both INPULSIS trials, the proportion of FVC responders, defined as patients with an absolute decline in FVC % predicted no greater than 5% (a threshold indicative of the increasing risk of mortality in IPF), was significantly higher in the nintedanib group as compared to placebo. Similar results were observed in analyses using a conservative threshold of 10%. See Table 3 for individual and pooled study results.

Additional evidence of efficacy is provided by the randomised, double-blind, placebo-controlled, dose finding phase II trial including a nintedanib 150 mg twice daily dose group.
The primary endpoint, rate of decline in FVC over 52 weeks was lower in the nintedanib arm (-0.060 L/year, N=84) than the placebo arm (-0.190 L/year, N=83). The estimated difference between the treatment groups was 0.131 L/year (95% CI 0.027, 0.235). The difference between the treatment groups reached nominal statistical significance (p=0.0136).
The estimated mean change from baseline in SGRQ total score at 52 weeks was 5.46 for placebo, indicating worsening of the health-related quality of life and -0.66 for nintedanib, indicating stable health-related quality of life. The estimated mean difference for nintedanib compared with placebo was -6.12 (95% CI: -10.57, -1.67; p=0.0071).
The number of patients with acute IPF exacerbations over 52 weeks was lower in the nintedanib group (2.3%, N=86) compared to placebo (13.8%, N=87). The estimated hazard ratio of nintedanib versus placebo was 0.16 (95% CI 0.04, 0.71; p=0.0054).
QT interval
In a dedicated study in renal cell cancer patients, QT/QTc measurements were recorded and showed that a single oral dose of 200 mg nintedanib as well as multiple oral doses of 200 mg nintedanib administered twice daily for 15 days did not prolong the QTcF interval.
Paediatric population
The European Medicines Agency has waived the obligation to submit the results of studies with Ofev in all subsets of the paediatric population in IPF (see section 4.2 for information on paediatric use).
5.2 Pharmacokinetic properties
Absorption
Nintedanib reached maximum plasma concentrations approximately 2 - 4 h after oral administration as soft gelatine capsule under fed conditions (range 0.5 - 8 h). The absolute bioavailability of a 100 mg dose was 4.69% (90% CI: 3.615 - 6.078) in healthy volunteers. Absorption and bioavailability are decreased by transporter effects and substantial first-pass metabolism. Dose proportionality was shown by increase of nintedanib exposure (dose range 50 - 450 mg once daily and 150 - 300 mg twice daily). Steady state plasma concentrations were achieved within one week of dosing at the latest.
After food intake, nintedanib exposure increased by approximately 20% compared to administration under fasted conditions (CI: 95.3 - 152.5%) and absorption was delayed (median tmax fasted: 2.00 h; fed: 3.98 h).
Distribution
Nintedanib follows at least bi-phasic disposition kinetics. After intravenous infusion, a high volume of distribution during the terminal phase (Vss: 1,050 L, 45.0% gCV) was observed.
The in vitro protein binding of nintedanib in human plasma was high, with a bound fraction of 97.8%. Serum albumin is considered to be the major binding protein. Nintedanib is preferentially distributed in plasma with a blood to plasma ratio of 0.869.
Biotransformation
The prevalent metabolic reaction for nintedanib is hydrolytic cleavage by esterases resulting in the free acid moiety BIBF 1202. BIBF 1202 is subsequently glucuronidated by uridine 5'-diphospho-glucuronosyltransferase enzymes (UGT) enzymes, namely UGT 1A1, UGT 1A7, UGT 1A8, and UGT 1A10 to BIBF 1202 glucuronide.
Only a minor extent of the biotransformation of nintedanib consisted of CYP pathways, with CYP 3A4 being the predominant enzyme involved. The major CYP-dependent metabolite could not be detected in plasma in the human ADME study. In vitro, CYP-dependent metabolism accounted for about 5% compared to about 25% ester cleavage. Nintedanib, BIBF 1202, and BIBF 1202 glucuronide did not inhibit or induce CYP enzymes in preclinical studies, either. Drug-drug interactions between nintedanib and CYP substrates, CYP inhibitors, or CYP inducers are therefore not expected.
Elimination
Total plasma clearance after intravenous infusion was high (CL: 1,390 mL/min, 28.8% gCV). Urinary excretion of the unchanged active substance within 48 h was about 0.05% of the dose (31.5% gCV) after oral and about 1.4% of the dose (24.2% gCV) after intravenous administration; the renal clearance was 20 mL/min (32.6% gCV). The major route of elimination of drug related radioactivity after oral administration of [14C] nintedanib was via faecal/biliary excretion (93.4% of dose, 2.61% gCV). The contribution of renal excretion to the total clearance was low (0.649% of dose, 26.3% gCV). The overall recovery was considered complete (above 90%) within 4 days after dosing. The terminal half-life of nintedanib was between 10 and 15 h (gCV % approximately 50%).
Linearity/non-linearity
The pharmacokinetics (PK) of nintedanib can be considered linear with respect to time (i.e. single-dose data can be extrapolated to multiple-dose data). Accumulation upon multiple administrations was 1.04-fold for Cmax and 1.38-fold for AUC. Nintedanib trough concentrations remained stable for more than one year.
Transport
Nintedanib is a substrate of P-gp. For the interaction potential of nintedanib with this transporter, see section 4.5. Nintedanib was shown to be not a substrate or inhibitor of OATP-1B1, OATP-1B3, OATP-2B1, OCT-2, or MRP-2 in vitro. Nintedanib was also not a substrate of BCRP. Only a weak inhibitory potential on OCT-1, BCRP, and P-gp was observed in vitro which is considered to be of low clinical relevance. The same applies for nintedanib being a substrate of OCT-1.
Population pharmocokinetic analysis in special populations
The PK properties of nintedanib were similar in healthy volunteers, patients with IPF, and cancer patients. Based on results of a Population PK (PopPK) analysis in patients with IPF and non small cell lung cancer (NSCLC) (N=1,191) and descriptive investigations, exposure to nintedanib was not influenced by sex (body weight corrected), mild and moderate renal impairment (estimated by creatinine clearance), alcohol consumption, or P-gp genotype. The PopPK analysis indicated moderate effects on exposure to nintedanib by age, body weight, and race, which are described in the following. Based on the high inter-individual variability of exposure observed moderate effects are considered not clinically relevant (see section 4.4).
Age
Exposure to nintedanib increased linearly with age. AUC,ss decreased by 16% for a 45-year old patient and increased by 13% for a 76-year old patient relative to a patient with the median age of 62 years. The age range covered by the analysis was 29 to 85 years; approximately 5% of the population were older than 75 years. Based on a PopPK model, an increase in nintedanib exposure of approximately 20 - 25% was observed in patients ≥ 75 years compared with patients under 65 years.
Studies in paediatric populations have not been performed.
Body weight
An inverse correlation between body weight and exposure to nintedanib was observed. AUC,ss increased by 25% for a 50 kg patient (5th percentile) and decreased by 19% for a 100 kg patient (95th percentile) relative to a patient with the median weight of 71.5 kg.
Race
The geometric mean exposure to nintedanib was 33% higher in Chinese, Taiwanese, and Indian patients while it was 22% lower in Koreans compared to Caucasians (body weight corrected). Data from Black individuals was very limited but in the same range as for Caucasians.
Hepatic impairment
Pharmocokinetic data for nintedanib was collected in patients with abnormalities in hepatic parameters defined by elevations in AST, ALT and bilirubin levels. A trend to elevated exposure was observed in patients with AST- and ALT-values (up to 10x ULN) and elevated bilirubin levels (up to 1.5x ULN) at baseline as compared to patients with normal AST, ALT and bilirubin levels. In patients with ALT or AST > 10x ULN and bilirubin > 1.5x ULN, data were too limited to draw conclusions.
Concomitant treatment with pirfenidone
In a small parallel group design study in Japanese patients with IPF (13 patients received nintedanib on top of chronic treatment with standard doses of pirfenidone; 11 patients received nintedanib alone), exposure to nintedanib decreased to 68.3% based on AUC and to 59.2% based on Cmax upon co-administration with pirfenidone pirfenidone compared to administration of nintedanib alone. Nintedanib had no effect on the PK of pirfenidone (see section 4.4).
5.3 Preclinical safety data
General toxicology
Single dose toxicity studies in rats and mice indicated a low acute toxic potential of nintedanib. In repeat dose toxicology studies in rats, adverse effects (e.g. thickening of epiphyseal plates, lesions of the incisors) were mostly related to the mechanism of action (i.e. VEGFR-2 inhibition) of nintedanib. These changes are known from other VEGFR-2 inhibitors and can be considered class effects.
Diarrhoea and vomiting accompanied by reduced food consumption and loss of body weight were observed in toxicity studies in non-rodents.
There was no evidence of liver enzyme increases in rats, dogs, and Cynomolgus monkeys. Mild liver enzyme increases, which were not due to serious adverse effects such as diarrhoea were only observed in Rhesus monkeys.
Reproduction toxicity
In rats, embryo-foetal lethality and teratogenic effects were observed at exposure levels below human exposure at the MRHD of 150 mg twice daily. Effects on the development of the axial skeleton and on the development of the great arteries were also noted at subtherapeutic exposure levels.
In rabbits, embryo-foetal lethality and teratogenic effects were observed at an exposure approximately 3 times higher than at the MRHD but equivocal effects on the embryo-foetal development of the axial skeleton and the heart were noted already at an exposure below that at the MRHD of 150 mg twice daily.
In a pre- and postnatal development study in rats, effects on pre- and post-natal development were seen at an exposure below the MRHD.
A study of male fertility and early embryonic development up to implantation in rats did not reveal effects on the male reproductive tract and male fertility.
In rats, small amounts of radiolabelled nintedanib and/or its metabolites were excreted into the milk (≤ 0.5% of the administered dose).
From the 2-year carcinogenicity studies in mice and rats, there was no evidence for a carcinogenic potential of nintedanib.
Genotoxicity studies indicated no mutagenic potential for nintedanib.
