Nintedanib

Nintedanib(656247-17-5) is an oral administrated triple tyrosine kinase inhibitors developed by Boehringer Ingelheim, Germany. Its targets include platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and basic fiber (BFGF), being able to also inhibit the activation of MAPK and Akt. At present, it is mainly used for cancer treatment, such as colorectal cancer, ovarian cancer and multiple myeloma. The study regarding to the respiratory diseases mainly focuses on the clinical treatment of advanced non-small cell lung cancer (NSCLC) and idiopathic pulmonary fibrosis (IPF). In June 2014, Boehringer Ingelheim has announced that the marketing authorization application of Nintedanib for the treatment of Idiopathic Pulmonary Fibrosis (IPF) had been confirmed by the European Medicines Agency (EMA) and been included in the accelerated approval list by the EMA.

Nintedanib(656247-17-5) is a small molecule that targets multiple receptor tyrosine kinases (RTKs) and non-receptor tyrosine kinases (nRTKs). Nintedanib inhibits the following RTKs: platelet-derived growth factor receptor (PDGFR) α and β, fibroblast growth factor receptor (FGFR) 1-3, vascular endothelial growth factor receptor (VEGFR) 1-3, and Fms-like tyrosine kinase-3 (FLT3). Among them, FGFR, PDGFR, and VEGFR have been implicated in IPF pathogenesis. Nintedanib binds competitively to the adenosine triphosphate (ATP) binding pocket of these receptors and blocks the intracellular signaling which is crucial for the proliferation, migration, and transformation of fibroblasts representing essential mechanisms of the IPF pathology. In addition, nintedanib inhibits the following nRTKs: Lck, Lyn and Src kinases. The contribution of FLT3 and nRTK inhibition to IPF efficacy is unknown.

Nintedanib ( Vargatef ) is an oral triple angiokinase inhibitor which simultaneously inhibits vascular endothelial growth factor receptors (VEGFR), platelet-derived growth factor receptors (PDGFR) and fibroblast growth factor receptors (FGFR) signalling pathways. Growing scientific evidence shows that these three different angiokinase receptors play an important role not only in angiogenesis but also in tumour growth and metastasis.
Nintedanib is currently being investigated in patients with various solid tumours including Phase III studies in advanced NSCLC, colorectal cancer (refractory to standard treatment) and ovarian cancer, and also in Phase II studies in mesothelioma, kidney cancer (renal cell carcinoma) and liver cancer (hepatic cell carcinoma).
In the EU, nintedanib in the treatment of idiopathic pulmonary fibrosis (IPF) has recently received a positive CHMP opinion. The U.S. Food and Drug Administration (FDA) has approved nintedanib capsules under the brand name OFEV for oral use for the treatment of IPF.

Idiopathic pulmonary fibrosis (IPF) is a progressive and ultimately fatal lung disease characterized by a progressive loss of lung function with worsening dyspnoea and cough. Development is thought to be instigated by repetitive lung injury (such as by cigarette smoke, industrial dusts, gastrooesophageal reflux and viral infection) leading to destruction of epithelial alveolar cells. Subsequent dysregulation of the repair process results in the proliferation/migration of fibroblasts and their differentiation into myofibroblasts, abnormal extracellular matrix deposition and excessive collagen accumulation in the lung interstitium and alveolar space, leading to progressive fibrosis and stiffening of the lungs. Vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF) and platelet-derived growth factor (PDGF) mediate various processes, including fibrogenesis and angiogenesis, and are implicated in the pathogenesis of IPF. By blocking substrate binding and downstream signalling cascades, nintedanib interferes with processes active in fibrosis such as fibroblast proliferation, migration and differentiation, and the secretion of extracellular matrix.

The most common side effects of Nintedanib in clinical studies were gastrointestinal-related side effects, including nausea (31%), vomiting (23%), diarrhoea (76%), abdominal pain (10%) and decreased appetite (10%). Other side effects were hepatic impairment commonly seen as elevated liver enzymes, weight loss (7 per cent), nasopharyngitis (7 per cent), cough (14 per cent), upper respiratory tract infections (14 per cent), headache (12 per cent), fatigue (14 per cent), skin ulcers (16 per cent) and urinary tract infections (12 per cent).
Reported post-marketing adverse events include gastrointestinal perforation, proteinuria and pancreatitis. In several clinical trials, nidanib has also been found to be associated with an increased risk of bleeding, possibly secondary to VEGFR inhibition. Although serious bleeding and arterial thromboembolic events (e.g., myocardial infarction (MI) and stroke) are rare, bleeding events with serious and fatal consequences have been reported in post-marketing surveillance. Therefore, the use of nidazanib has been associated with an increased risk of bleeding, possibly secondary to VEGFR inhibition. Therefore, patients treated with nidazanib and receiving full anticoagulation therapy need to be closely monitored for adverse bleeding events.

Potentially hazardous interactions with other drugs
Antibacterials: concentration reduced by rifampicin - avoid.
Antifungals: concentration increased by ketoconazole.
Antipsychotics: increased risk of agranulocytosis with clozapine - avoid.

Nintedanib is metabolised in the liver, initially by hydrolytic cleavage by esterases and then by glucuronidation by uridine diphosphate glucuronosyltransferase enzymes. Only a minor portion is metabolised by cytochrome P450 isoenzymes, mainly CYP3A4. More than 90% of a dose is eliminated by faecal/biliary excretion.
