CONTRAINDICATIONS / PRECAUTIONS
Asian patients, females, geriatric, hepatic disease, hepatotoxicity, jaundice
Reduce the dose of nintedanib in patients with mild hepatic disease (Child Pugh A). Nintedanib is not recommended in patients with moderate or severe hepatic disease (Child Pugh B or C); it has not been studied in patients with severe hepatic disease. Nintedanib therapy may cause elevated bilirubin and liver enzymes, but increases in liver enzymes are usually reversible with dose modification or interruption of therapy. During postmarketing surveillance, non-serious and serious cases of drug-induced hepatotoxicity, including severe liver injury with fatal outcome, were reported. Patients with a low body weight (weighing less than 65 kg), Asian patients, and females may have a higher risk of elevations in liver enzymes. Since nintedanib exposure increases with patient age, geriatric patients may also be at a higher risk of increased liver enzymes. Check liver function tests (LFTS) and bilirubin concentrations before starting treatment, at regular intervals during the first 3 months, and periodically thereafter, and as clinically indicated. Dosage modification or interruption of nintedanib therapy may be necessary for elevated liver enzymes. If serious liver injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during nintedanib therapy, promptly interrupt therapy.
Anticoagulant therapy, bleeding
Use nintedanib in patients with a known risk of bleeding only if the benefits of therapy outweigh the risks. For patients receiving nintedanib concurrently with anticoagulant therapy, closely monitor for bleeding and adjust anticoagulation treatment as necessary. Nintedanib may increase the risk of bleeding, based on its mechanism of action as a VEGFR inhibitor. In the idiopathic pulmonary fibrosis (IPF) clinical trials, bleeding events occurred more often in patients treated with nintedanib than in the placebo group (10% vs. 7%). Similarly, in the systemic sclerosis-associated interstitial lung disease (SSc-ILD) clinical trial, bleeding events were reported by 11% of nintedanib recipients compared to 8% of patients who received a placebo. However, in the chronic fibrosing interstitial lung diseases (ILDs) trial, a higher percentage of placebo recipients experienced a bleeding event compared with the nintedanib treatment group (13% vs. 11%). Bleeding events, both non-serious and serious (some fatal), have also been reported during postmarketing use of the drug.[58203]
Acute myocardial infarction, coronary artery disease, myocardial infarction, stroke
Serious arterial events, including myocardial infarction (MI), have been reported with nintedanib use. Nintedanib should be used with caution in patients at increased cardiovascular risk, including known coronary artery disease or ischemia. Encourage patients receiving nintedanib to seek immediate medical attention if they experience symptoms suggesting a heart attack (e.g., chest pain or pressure, pain in their arms, back, neck or jaw, or shortness of breath) or symptoms of a stroke (e.g., numbness or weakness on one side of the body, trouble talking, or severe head pain). Consider treatment interruption in patients who develop signs or symptoms of acute myocardial infarction, stroke, or other serious arterial events.
Corticosteroid therapy, diarrhea, diverticulitis, GI perforation, surgery, vomiting
Gastrointestinal (GI) events such as diarrhea and nausea and/or vomiting are common with nintedanib therapy and may require supportive measures to control. Treat diarrhea at first signs with adequate hydration and antidiarrheal medication (e.g., loperamide); use supportive care for nausea and vomiting, including anti-emetic treatment. Consider treatment interruption if diarrhea or vomiting continues despite support measures, until resolution, after which nintedanib may be resumed at full or reduced dosage, followed by titration. If severe symptoms persist, consider permanent discontinuation of treatment. Nintedanib may increase the risk of GI perforation based on its mechanism of action as a VEGFR inhibitor. Use nintedanib in patients with a known risk of GI perforation only if the benefits of therapy outweigh the risks. Use caution when treating patients who have recently had abdominal surgery, have a previous history of diverticular disease (diverticulitis), or who are receiving concomitant corticosteroid therapy or NSAIDs. In the idiopathic pulmonary fibrosis (IPF) clinical trials, GI perforation occurred more often in patients treated with nintedanib than in the placebo group (0.3% vs 0%). No cases of GI perforation were associated with the use of nintedanib during the chronic fibrosing interstitial lung diseases (ILDs) or systemic sclerosis-associated interstitial lung disease (SSc-ILD) clinical trials. During postmarketing surveillance, cases of GI perforation have been reported, some of which were fatal. The typical presentation may include abdominal pain associated with symptoms such as constipation, fever, nausea, and vomiting. Nintedanib therapy should be permanently discontinued in patients with GI perforation.
Proteinuria
Cases of proteinuria within the nephrotic range have been reported with postmarketing use of nintedanib. When available, histological findings were consistent with glomerular microangiopathy with or without renal thrombi. Although improvement in proteinuria was observed following nintedanib discontinuation; some patients experienced residual, persistent proteinuria. Consider interruption of nintedanib therapy in patients who develop new or worsening proteinuria.
Tobacco smoking
Tobacco smoking was associated with decreased nintedanib exposure, which may decrease the efficacy of treatment. Patients should be encouraged to stop smoking before initiating nintedanib treatment and to avoid smoking during therapy.
Pregnancy
Do not use nintedanib during pregnancy; rule out pregnancy in a female of childbearing potential prior to initiation of nintedanib. Females of reproductive potential should avoid becoming pregnant during nintedanib therapy and for at least 3 months after the last dose of nintedanib. In animal reproduction toxicity studies, nintedanib was teratogenic and embryofetocidal in rats and rabbits at exposures 5 times or less that of the maximum recommended human dose (MRHD) in adults. Malformations included abnormalities in the vasculature (missing or additional major blood vessels), urogenital (missing organs), and skeletal systems. Skeletal anomalies included abnormalities in the thoracic, lumbar, and caudal vertebrae (e.g., hemivertebra, missing, or asymmetrically ossified), ribs (bifid or fused), and sternebrae (fused, split, or unilaterally ossified). In rabbits, a significant change in sex ratio was observed in fetuses (female:male of approximately 71%:29%) at an AUC equivalent to approximately 15 times the MRHD. The post-natal viability of rat pups during the first 4 post-natal days was also reduced when dams were exposed to an AUC equivalent to less than the MRHD.
Contraception requirements, infertility, pregnancy testing, reproductive risk
Counsel female patients about the reproductive risk and contraception requirements during nintedanib treatment. Females of reproductive potential should undergo pregnancy testing prior to initiation of nintedanib and during treatment as appropriate and avoid pregnancy while taking the drug. Women who become pregnant while receiving nintedanib should be apprised of the potential hazard to the fetus. Females of childbearing potential should use highly effective contraception during and for at least 3 months after the final dose of nintedanib. It is currently unknown whether nintedanib may reduce the effectiveness of hormonal contraceptives, therefore advise women using hormonal contraceptives to add a barrier method. Based on animal data, female fertility may be reduced, resulting in possible infertility, with the use of nintedanib. Nintedanib did not affect male fertility in animal studies.
Breast-feeding
Breast-feeding is not recommended during nintedanib treatment, because of the potential for serious adverse reactions in a nursing infant. There is no information on the presence of nintedanib in human milk, the effects on the breast-fed infant or the effects on milk production. Nintedanib and/or its metabolites are present in the milk of lactating rats; the milk and plasma of lactating rats have similar concentrations of nintedanib and its metabolites.
Children, infants
The safety and efficacy of nintedanib have not been established in adolescents, children or infants.
