Henatinib was developed as a multitargeted tyrosine kinase inhibitor with antitumor activities. Henatinib is an endothelial growth factor receptor type 2 (VEGFR2) antagonist. The drug participated in phase I clinical trial to evaluate the safety and tolerability in patients with advanced solid malignancies, however, the study was terminated. The current development status is unknown.

Lucitanib (E-3810) is a novel multi-kinase inhibitor currently in clinical trials for its anti-angiogenic and anti-tumor activity. A Phase I/IIa clinical trial of lucitanib was initiated in 2010 and has demonstrated multiple objective responses in FGFR1 gene-amplified breast cancer patients, and objective responses were also observed in patients with tumors often sensitive to VEGFR inhibitors, such as renal cell and thyroid cancer. Lucitanib is an oral, potent inhibitor of the tyrosine kinase activity of fibroblast growth factor receptors 1 through 3 (FGFR1-3), vascular endothelial growth factor receptors 1 through 3 (VEGFR1-3) and platelet-derived growth factor receptors alpha and beta (PDGFR alpha-beta). The most common adverse events were hypertension, asthenia, and proteinuria.

AZD-4547 is an orally bioavailable inhibitor of the fibroblast growth factor receptor (FGFR) with potential antineoplastic activity. FGFR inhibitor AZD4547 binds to and inhibits FGFR, which may result in the inhibition of FGFR-related signal transduction pathways, and, so, the inhibition of tumor cell proliferation and tumor cell death. FGFR, up-regulated in many tumor cell types, is a receptor tyrosine kinase essential to tumor cellular proliferation, differentiation and survival. AZD-4547 is a selective FGFR inhibitor targeting FGFR1/2/3 with IC50 of 0.2 nM/2.5 nM/1.8 nM in cell-free assays, weaker activity against FGFR4, VEGFR2 (KDR), and little activity observed against IGFR, CDK2, and p38. Compared to FGFR1-3, AZD-4547 displays weaker activity against FGFR4 with IC50 of 165 nM. AZD-4547 only inhibits recombinant VEGFR2 (KDR) kinase activity with IC50 of 24 nM, in the in vitro selectivity test against a diverse panel of representative human kinases. AZD-4547 is under clinical investigation for the treatment of FGFR-dependent tumors. It is in phase II clinical studies for the treatment of breast cancer; gastric cancer; lung cancer; oesophageal cancer and in phase II/III clinical studies for the treatment of non-small cell lung cancer.

Golvatinib is a highly potent, small-molecule, ATP-competitive inhibitor of c-Met and multiple members of the Eph receptor family plus c-Kit and Ron. Eisai was developing an oral formulation of golvatinib, which acts as both a c-Met inhibitor and a vascular endothelial growth factor receptor 2 antagonist with potential antineoplastic activity. Golvatinib binds to and inhibits the activities of both c-Met and VEGFR-2, which may inhibit tumor cell growth and survival of tumor cells that overexpress these receptor tyrosine kinases. c-Met and VEGFR-2 are upregulated in a variety of various tumor cell types and play important roles in tumor cell growth, migration and angiogenesis. Clinical trials involving several forms of cancer are currently underway.

CGI-1842 (also known as JI-101) is an oral multi-kinase inhibitor that targets vascular endothelial growth factor receptor type 2 (VEGFR-2), platelet derived growth factor receptor β (PDGFR-β), and ephrin type-B receptor 4 that has been used in trials studying the treatment of Cancer, Colon Cancer, Neuroendocrine, Ovarian Cancer, and Advanced Solid Tumors. By targeting multiple angiogenesis signaling pathways in tumor vessel beds, CGI-1842 has the potential to inhibit multiple stages of tumor angiogenesis and thus enhance anti-tumor efficacy. In preclinical models, CGI-1842 induced concentration-dependent blocking of both EphB4- and VEGF-stimulated signaling pathways and has shown excellent antitumor activity. CGI-1842 is well tolerated in cancer patients and has shown impressive activity in Phase I clinical trials.

AGE-RELATED MACULAR DEGENERATION (AMD), PROLIFERATIVE DIABETIC RETINOPATHY (PDR) AND DIABETIC MACULAR EDEMA (DME) are collectively characterized by VEGF mediated retinal leakage, angiogenesis, and an underlying inflammatory process. TargeGen's TG100801 is designed to inhibit a select group of kinases involved in those three processes. Currently approved drug based therapy for macular degeneration requires repeated injection into the eye. TG100801 is the first topically applied, VEGFR)/Src kinase inhibitor to advance into the clinic for the treatment of Age-related macular degeneration, diabetic retinopathy. The formation of new blood vessels (angiogenesis), blood vessel leakage, and inflammation contribute to the progression of the eye disease, which is the leading cause of irreversible, severe loss of vision in people 55 years of age and older in the developed world. In cell based assays, following topical instillation, TG100572, the active drug produced by conversion of TG100801 as it penetrates the eye, was shown to induce apoptosis in proliferating endothelial cells responsible for neovasculariztion and to inhibit inflammatory-mediated processes as measured by endotoxin-induced nitric oxide release in vitro.

AEE-788 is an orally available anticancer agent that was being developed by Novartis. AEE-788 is a dual family epidermal growth factor receptor/ErbB2 and vascular endothelial growth factor receptor tyrosine kinase inhibitor with antitumor and antiangiogenic activity. At the enzyme level, AEE-788 inhibited EGFR and VEGF receptor tyrosine kinases in the nm range (IC(50)s: EGFR 2 nm, ErbB2 6 nm, KDR 77 nm, and Flt-1 59 nm). In cells, growth factor-induced EGFR and ErbB2 phosphorylation was also efficiently inhibited (IC(50)s: 11 and 220 nm, respectively). AEE-788 demonstrated antiproliferative activity against a range of EGFR and ErbB2-overexpressing cell lines (including EGFRvIII-dependent lines) and inhibited the proliferation of epidermal growth factor- and VEGF-stimulated human umbilical vein endothelial cells. These properties, combined with a favorable pharmacokinetic profile, were associated with a potent antitumor activity in a number of animal models of cancer, including tumors that overexpress EGFR and or ErbB2. Oral administration of AEE-788 to tumor-bearing mice resulted in high and persistent compound levels in tumor tissue. Moreover, AEE-788 efficiently inhibited growth factor-induced EGFR and ErbB2 phosphorylation in tumors for >72 h, a phenomenon correlating with the antitumor efficacy of intermittent treatment schedules. AEE-788 has potential as an anticancer agent targeting deregulated tumor cell proliferation as well as angiogenic parameters. AEE-788 had been in phase Ⅱ clinical trials by Novartis for the treatment of glioblastoma multiforme. However, this research has been discontinued.

Brivanib is a pyrrolotriazine-based compound and an inhibitor of vascular endothelial growth factor receptor-2 (VEGFR-2) with potential antineoplastic activity. It specifically targets and strongly binds to human VEGFR-2, a tyrosine kinase receptor and pro-angiogenic growth factor expressed almost exclusively on vascular endothelial cells. Blockade of VEGFR-2 by this agent may lead to an inhibition of VEGF-stimulated endothelial cell migration and proliferation, thereby inhibiting tumor angiogenesis. Brivanib has a moderate potency compared to VEGFR-2 against VEGFR-1 and FGFR-1 as well. Brivanib is suggested to be efficient in treatment of hepatocellular carcinoma (HCC). As first-line and as second-line therapy brivanib demonstrated promising antitumor activity and a manageable safety profile in patients with advanced, unresectable HCC in phase II clinical trials. On 3 march 2011, orphan designation was granted by the European Commission to Bristol-Myers Squibb for brivanib alaninate for the treatment of hepatocellular carcinoma.[

CEP-32496 (RXDX 105) is an orally administered, small molecule, VEGFRsparing, RET, BRAF, EGFR tyrosine kinase inhibitor, for the treatment of solid tumours, including malignant melanoma and colorectal cancer. CEP-32496 was originally discovered by Ambit Biosciences (now Daiichi Sankyo) and Cephalon (now owned by Teva) as part of a research programme to develop orally administered kinase inhibitors. The worldwide rights to the compound were licensed to Teva by Ambit, following the acquisition of Cephalon by Teva. Teva, in March 2015, entered into an asset purchase agreement with Ignyta, pursuant to which, Ignyta has acquired worldwide rights and assets of four oncology development programmes, including CEP-32496. Following the acquisition of the compound by Ignyta, CEP 32496 has been renamed to RXDX 105. Phase I/Ib development of RXDX 105 for the treatment of advanced solid tumours is underway in the US.

Vatalanib a potent oral tyrosine kinase inhibitor with a selective range of molecular targets, has been extensively investigated and has shown promising results in patients with solid tumors in early trials. Vatalanib selectively inhibits the tyrosine kinase domains of vascular endothelial growth factor (VEGF) receptor tyrosine kinases (important enzymes in the formation of new blood vessels that contribute to tumor growth and metastasis), platelet-derived growth factor (PDGF) receptor, and c-KIT. The adverse effects of vatalanib appear similar to those of other VEGF inhibitors. In the CONFIRM trials, the most common side effects were high blood pressure, gastrointestinal upset (diarrhea, nausea, and vomiting), fatigue, and dizziness.
