nintedanib and Neoplasms

A meta-analysis of the risk of selected gastrointestinal and hepatic toxicities associated with nintedanib has been conducted.. Randomized Phase II/III trials of cancer patients on nintedanib; describing events of diarrhea, vomiting, elevated ALT and elevated AST constituted the eligible studies.. The odds ratio for high-grade diarrhea was 3.76 (95% CI: 1.42-9.96; p = 0.008); high-grade vomiting: 1.38 (95% CI: 0.76-2.51; p = 0.28); high-grade elevated ALT: 4.36 (95% CI: 2.14-8.85; p < 0.0001); high-grade elevated AST: 6.96 (95% CI: 4.09-11.85; p < 0.00001).. Nintedanib-based regimens are associated with a higher risk of high-grade diarrhea, elevated ALT and elevated AST. Moreover, there is a proportional relationship between nintedanib dose and the risk of elevated transaminases.

Antiangiogenic agents are effective standard-of-care options in several malignancies, but are generally associated with only modest improvements in survival, as well as leading to additional toxicities. Furthermore, almost all patients develop acquired resistance to therapy, possibly due to the activation of alternative proangiogenic pathways. Here we discuss: the rationale for developing nintedanib, an agent that simultaneously inhibits signaling pathways activated by platelet-derived growth factor, FGF, as well as VEGF; how its distinctive inhibitory and pharmacokinetic profile could underlie promising efficacy and tolerability observed in Phase II trials in patients with relapsed/refractory non-small cell lung cancer, advanced ovarian cancer and metastatic colorectal cancer; the ongoing Phase III program that is assessing nintedanib in these areas of major unmet medical need; and recent progress in the development of biomarkers that may predict response to nintedanib.

Angiogenesis is considered one of the major components of tumor progression and metastasis. Interfering with the formation and stabilization of tumor blood vessels could increase tumor response rates and may translate into improved clinical outcomes in cancer patients. The clinical efficacy demonstrated in phase III trials with bevacizumab, a monoclonal antibody that targets vascular endothelial growth factor ligand, suggests that targeting angiogenesis is a rational approach to cancer management. Agents that target additional proangiogenic intracellular signaling pathways also have the potential to contribute to our anticancer armamentarium. Novel targeted agents that have antiangiogenic properties have been developed in recent years such as sorafenib, sunitinib, vandetanib, and others. Many of them inhibit additional pathways beyond vascular endothelial growth factor signaling. One of these investigational targeted agents is a triple angiokinase inhibitor known as BIBF 1120. This compound targets not only vascular endothelial growth factor receptors, but also fibroblast growth factor receptors, and platelet-derived growth factor receptors. The preliminary clinical efficacy of BIBF 1120 is discussed in the context of the most relevant clinical data in several malignancies including non-small cell lung cancer.

Functional blood vasculature is essential for tumor progression. The main signalization pathways that play a key role in the survival and growth of tumor vessels originate from the VEGF-, PDGF- and FGF tyrosine kinase receptors. In the past decade, significant results have been published on receptor tyrosine kinase inhibitors (RTKIs). In this paper, the mechanisms of action and the results so far available of experimental and clinical studies on multi-target antiangiogenic TKIs are discussed. On the one hand, notable achievements have been made recently and these drugs are already used in clinical practice in some patient populations. On the other hand, the optimal combination and dosage of these drugs, selection of the apropriate biomarker and better understanding of the conflicting role of PDGFR and FGFR signaling in angiogenesis remain future challenges.

Angiogenesis is essential for tumor growth and metastasis. The main regulators of the process are the signaling cascades of VEGF-, PDGF- and FGF receptors. Inhibition of these pathways holds potential therapeutic benefit not only for cancer patients, but also for the treatment of other diseases. This paper summarizes the experimental and clinical results of studies available so far on the multi-target tyrosine kinase inhibitor nintedanib (BIBF 1120). According to these studies, nintedanib effectively inhibits VEGFR-, PDGFR- and FGFR signalization and thus the proliferation and survival of cell types which highly express these receptors (i.e. endothelial and smooth muscle cells and pericytes). In vitro studies and in vivo xenograft experiments have provided promising results. In the clinical setting, BIBF 1120 seems to be effective and well tolerated in various tumor types, such as lung, prostate, colorectal and hepatocellular carcinoma, as well as in gynecological tumors. The main adverse events are gastrointestinal toxicities and the reversible elevation of liver enzyme levels. Nintedanib might also be combined with paclitaxel, carboplatin, pemetrexed and docetaxel. There are several ongoing clinical trials testing the efficacy of BIBF 1120.

Tyrosine kinase receptors have important signaling functions in various physiological and pathological pathways. The recognition of their involvement in tumor angiogenesis, which is the main event of tumor progression, opened a new era in the discovery of anticancer drugs. Developers soon grasped that by targeting several tyrosine kinase receptors at once, so-called multitarget tyrosine kinase inhibitors, a drug could dramatically affect the progression of cancer and decrease resistance. Several antiangiogenic, multitarget tyrosine kinase inhibitors, such as sorafenib and sunitinib, are already marketed, while many more are undergoing clinical trials for a range of cancer types. Boehringer Ingelheim Corp is developing intedanib (BIBF-1120), a triple kinase inhibitor blocking VEGFR, PDGFR and FGFR for the treatment of several malignancies and idiopathic pulmonary fibrosis. The preliminary data for intedanib appears at least as good as that for other antiangiogenic tyrosine kinase inhibitors or other antiangiogenic approaches that are not targeting the tyrosine kinases. The sustained inhibition of VEGFR phosphorylation (> 24 h), the fast in vivo clearance and clinical efficacy against a broad range of malignancies appear to be the major advantages of intedanib. Furthermore, the existing data suggest an excellent safety profile. At the time of publication, intedanib had reached phase III trials for the treatment of NSCLC and ovarian cancer.

We aimed to determine the safety and efficacy of nintedanib, an oral anti-angiogenic tyrosine kinase inhibitor, in combination with pembrolizumab, an anti-PD1 immunotherapy, in patients with advanced solid tumors (PEMBIB trial; NCT02856425).. In this monocentric phase Ib dose escalation cohort, we evaluated escalating doses of nintedanib (Dose level 1 (DL1) = 150 mg bid [bis in die, as twice a day]; DL2 = 200 mg bid, oral delivery) in combination with pembrolizumab (200 mg Q3W, IV). Patients received a 1-week lead-in dose of nintedanib monotherapy prior starting pembrolizumab. The primary objective was to establish the maximum tolerated dose (MTD) of the combination based on dose limiting toxicity (DLT) occurrence during the first 4 weeks. Secondary objectives were to assess the anti-tumor efficacy and to identify the associated immune and angiogenic parameters in order to establish the recommended nintedanib dose for expansion cohorts. Flow cytometry (FC), Immuno-Histo-Chemistry (IHC) and electrochemiluminescence multi-arrays were prospectively performed on baseline & on-treatment tumor and blood samples to identify immune correlates of efficacy.. A total of 12/13 patients enrolled were evaluable for DLT (1 patient withdrew consent prior receiving pembrolizumab). Three patients at 200 mg bid experienced a DLT (grade 3 liver enzymes increase). Four patients developed grade 1-2 immune related adverse events (irAE). Eight patients died because of cancer progression. Median follow-up was 23.7 months (95%CI: 5.55-40.5). Three patients developed a partial response (PR) (ORR = 25%) and five patients (42%) had durable clinical benefit (DCB), defined as PR or stable disease (SD) ≥ 6 months. At baseline, patients with DCB had higher plasma levels of Tie2, CXCL10, CCL22 and circulating CD4. Nintedanib 150 mg bid is the recommended dose for combination with pembrolizumab and is currently investigated in multiple expansion cohorts. Early tumoral and circulating immune factors were associated with cancer outcome under nintedanib & pembrolizumab therapy.. ClinicalTrials.gov, NCT02856425 . Registered August 4, 2016 - Prospectively registered.

Vascular endothelial growth factor (VEGF) inhibitors have produced demonstrable but limited benefit for various cancers. One mechanism of resistance includes revascularization, secondary to upregulation of alternative pro-angiogenic platelet-derived growth factor receptor and fibroblast growth factor receptor pathways. Nintedanib is an oral, triple kinase inhibitor that blocks these pathways and may improve anti-tumor activity by overcoming resistance to anti-VEGF therapies. The primary objective of this first in-human study was to evaluate the safety and tolerability of nintedanib in combination with bevacizumab.. Patients were treated with escalating doses of nintedanib (150 mg or 200 mg oral twice daily) and bevacizumab (15 mg/kg once intravenously every 3 weeks) until disease progression or unacceptable toxicity using standard 3 + 3 phase 1 design. Plasma levels of angiogenic biomarkers were correlated with clinical outcomes.. Eighteen patients with advanced tumors [lung (n = 9), colon (n = 8), and cervical (n = 1)] previously treated with at least two lines of chemotherapy including bevacizumab (n = 9, 50%) were enrolled. The highest dose of nintedanib was 200 mg twice a day with no observed dose-limiting toxicities (DLT). Common adverse events (AE) were fatigue (grade 1-3) and diarrhea (grade 1-2). Durable clinical response was observed in 55% patients pretreated with bevacizumab (1 complete and 4 stable response). Better disease control was correlated with higher than median baseline values for VEFGR2 and E-selectin, and lower levels for SDF-1α.. Nintedanib was well-tolerated with bevacizumab with no DLT. Significant clinical activity was observed, including in bevacizumab-pretreated patients, suggesting nintedanib can overcome bevacizumab resistance.

This open-label phase I dose-escalation study investigated the safety, efficacy, pharmacokinetics (PK), and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) effects of the oral angiokinase inhibitor nintedanib in patients with advanced solid tumors.. Nintedanib was administered once daily continuously, starting at 100 mg and later amended to allow evaluation of 250 mg b.i.d. The primary endpoint was maximum tolerated dose (MTD). DCE-MRI studies were performed at baseline and on days 2 and 28.. Fifty-one patients received nintedanib 100-450 mg once daily (n = 40) or 250 mg b.i.d. (n = 11). Asymptomatic reversible liver enzyme elevations (grade 3) were dose limiting in 2 of 5 patients at 450 mg once daily. At 250 mg b.i.d., 2 of 11 patients experienced dose-limiting toxicity (grade 3 liver enzyme elevation and gastrointestinal symptoms). Common toxicities included fatigue, diarrhea, nausea, vomiting, and abdominal pain (mainly grade ≤2). Among 45 patients, 22 (49%) achieved stable disease; 7 remained on treatment for >6 months. DCE-MRI of target lesions revealed effects in some patients at 200 and ≥400 mg once daily.. Nintedanib is well tolerated by patients with advanced solid malignancies, with MTD defined as 250 mg b.i.d., and can induce changes in DCE-MRI. Disease stabilization >6 months was observed in 7 of 51 patients.

To evaluate the safety and maximum tolerated dose (MTD) of afatinib combined with nintedanib.. Patients received afatinib 10-20 mg daily plus nintedanib 150-200 mg twice daily (28-day cycle). Dose escalation followed a 3+3 design.. Patients received afatinib/nintedanib: 10/150 mg (n = 11); 10/200 mg (n = 13; MTD); 20/200 mg (n = 4). Four patients had dose-limiting toxicities (all grade 3): increased alanine aminotransferase (afatinib/nintedanib: 10/150 mg), diarrhea (10/200 mg), dehydration (20/200 mg), diarrhea with elevated liver enzymes (20/200 mg). Frequent treatment-related adverse events were diarrhea, nausea, anorexia, fatigue and vomiting. In total, 14 patients (46.2%) had objective responses at the MTD.. The MTD, afatinib 10 mg daily plus nintedanib 200 mg twice daily, had a manageable safety profile, but was considered subtherapeutic for Phase II evaluation.

Volasertib is a potent and selective cell-cycle kinase inhibitor that induces mitotic arrest and apoptosis by targeting Polo-like kinases. This study determined the maximum tolerated dose (MTD) and pharmacokinetics of volasertib combined with nintedanib, a potent and orally bioavailable triple angiokinase inhibitor, in patients with advanced solid tumors.. This open-label, dose-escalation trial recruited patients with advanced metastatic solid tumors following failure of conventional treatment (NCT01022853; Study 1230.7). Volasertib was administered by intravenous infusion over 2 h, starting at 100 mg in the first dose cohort. Nintedanib was administered orally at a dose of 200 mg twice daily. The first treatment cycle comprised 28 days (days 1-7 and days 9-28: nintedanib; day 8: volasertib). From cycle 2 onwards, volasertib was administered on day 1 of a 21-day cycle and nintedanib was administered days 2-21. The primary objective was the MTD of volasertib in combination with nintedanib.. Thirty patients were treated. The MTD of volasertib plus fixed-dose nintedanib was 300 mg once every 3 weeks, the same as the recommended single-agent dose of volasertib in solid tumors. Two of 12 assessable patients treated with the MTD experienced dose-limiting toxicities [grade 3 increased alanine aminotransferase (ALT); grade 3 ALT increase and grade 3 increased aspartate aminotransferase]. Disease control [stable disease (SD)/partial response (PR)/complete response (CR)] was achieved in 18 patients (60%): 1 CR (breast cancer), 1 PR (nonsmall-cell lung cancer), and 16 patients with SD. Volasertib showed that multiexponential pharmacokinetic behavior and co-administration of nintedanib had no significant effects on its exposure.. Volasertib could be combined with fixed-dose nintedanib at the recommended single-agent dose. At this dose, the combination had a manageable safety profile without unexpected or overlapping adverse events, and showed antitumor activity.

BIBF 1120 is an oral, potent angiokinase inhibitor targeting receptors of the vascular endothelial growth factors, platelet-derived growth factors, and fibroblast growth factors. This phase I, accelerated titration study assessed the maximum tolerated dose, safety, pharmacokinetics, and pharmacodynamic effects of BIBF 1120.. Sixty-one patients with advanced cancers received BIBF 1120 in successive cohorts. Twenty-five received 50 to 450 mg once daily and 36 received 150 to 300 mg twice daily in 4-week treatment courses interspersed by 1 week of washout. Dynamic contrast-enhanced magnetic resonance imaging assessed antiangiogenic effect in 42 patients.. Most frequent BIBF 1120-related adverse events were mostly mild to moderate (Common Toxicity Criteria grade 1-2) nausea (68.9%), vomiting (45.9%), and diarrhea (44.3%). The majority of dose-limiting adverse events of Common Toxicity Criteria grade 3 or 4 were reversible liver enzyme elevations. The maximum tolerated dose was 250 mg of BIBF 1120 for once and twice daily dosing. BIBF 1120 was absorbed moderately fast (t(max) = 1-3 hours at steady state), with no deviation from dose linearity and no decrease of exposure over time. The gMean terminal half-life was from 13 to 19 hours. One complete and two partial responses occurred in patients with renal cell cancer (n = 2) and colorectal cancer (n = 1). Dynamic contrast-enhanced magnetic resonance imaging showed a significant reduction in tumor blood flow in 55% of evaluable patients.. BIBF 1120 dosed continuously displayed a favorable safety and pharmacokinetics profile, and first efficacy signals were observed. Twice daily dosing permitted increased drug exposure without additional toxicity. Two hundred milligrams BIBF 1120 twice daily is the recommended dose for phase II monotherapy studies.

BIBF 1120 is an oral multitargeted tyrosine kinase inhibitor that blocks the activity of vascular endothelial growth factor (VEGF) and other growth factor receptors. We have done a phase I study to evaluate the safety, pharmacokinetics, and pharmacodynamic biomarkers of BIBF 1120. Patients with advanced refractory solid tumors were treated with BIBF 1120 at oral doses of 150 to 250 mg twice daily. Drug safety and pharmacokinetics were evaluated, as were baseline and post-treatment levels of circulating CD117-positive bone marrow-derived progenitor cells and plasma soluble VEGF receptor 2 as potential biomarkers for BIBF 1120. Twenty-one patients were treated at BIBF 1120 doses of 150 (n = 3), 200 (n = 12), or 250 mg twice daily (n = 6). Dose-limiting toxicities of reversible grade 3 or 4 elevations of liver enzymes occurred in 3 of 12 patients at 200 mg twice daily and 3 of 6 patients at 250 mg twice daily. Stable disease was achieved in 16 (76.2%) patients, and median progression-free survival was 113 days (95% confidence interval, 77-119 d). Pharmacokinetic analysis indicated that the maximum plasma concentration and area under the curve for BIBF 1120 increased with the dose within the dose range tested. Levels of CD117-positive bone marrow-derived progenitors and soluble VEGF receptor 2 decreased significantly during treatment over all BIBF 1120 dose cohorts. In conclusion, the maximum tolerated dose of BIBF 1120 in the current study was determined to be 200 mg twice daily, and our biomarker analysis indicated that this angiokinase inhibitor is biologically active.

Albumin nanoparticles represent an approved anti-tumor drug delivery system. However, there is only one albumin nanoparticle product (paclitaxel-albumin nanoparticle) on the market. The application of albumin carriers is limited by the lack of universal preparation technology and insufficient targeting effect. Herein, we developed multifunctional albumin sub-microspheres prepared by coaxial-electrospray technology to co-delivery bufalin and nintedanib for tumor-targeted combination therapy. The biguanide and ursodeoxycholic acid dual-modified multifunctional albumin was synthesized to enhance the anti-tumor effect and tumor target efficiency. Coaxial-electrospray technology was utilized in preparing albumin sub-microspheres with a core-shell structure that enables payload efficiency and stability. More importantly, the in vitro and in vivo experiments demonstrated that the multifunctional albumin sub-microspheres possessed superior tumor target efficiency. Furthermore, nintedanib and bufalin combined therapy relieved the tumor microenvironment and exerted a synergistic therapeutic effect. Therefore, this work provides a novel method for fabricating an albumin-based drug delivery system and a potential efficient combination therapeutic strategy for tumor treatment.
