Project description:This is a clinical trial investigating the effectiveness and safety of the combination of the study drugs bevacizumab and AMG386 in patients with advanced (metastatic) chemotherapy-naive bowel (colorectal) cancer. Chemotherapy has a significant impact in metastatic bowel cancer in terms of maintenance of quality of life and extension of survival. However, ultimately tumours will develop resistance to these agents and further treatment options are urgently required.
Angiogenesis is a process that results in the formation of new blood vessels. Similar to normal tissues, solid tumours require new blood vessels for growth and survival. Hence, drugs targeting angiogenesis may be useful treatment options for patients with bowel cancer.
AMG386 and bevacizumab act on 2 different pathways relevant to angiogenesis. There is evidence from laboratory and animal studies to suggest that such a combination could be useful as a cancer treatment. Previous studies in humans have shown that AMG386 and bevacizumab can be combined safely.. This study aims to evaluate the effectiveness and safety of the combination of AMG386 and bevacizumab in patients with advanced bowel cancer.
40 patients from approximately four hospitals in Australia will participate in this trial, with approximately 20 patients being enrolled at Austin Health. All participants will receive the same treatment.

Project description:The increased expression of vascular endothelial growth factor (VEGF) and its receptors is associated with angiogenesis in a growing tumor, presenting potential targets for tumor-selective imaging by way of targeted tracers. Though fluorescent tracers are used for targeted in vivo imaging, the lack of photostability and biocompatibility of many current fluorophores hinder their use in several applications involving long-term, continuous imaging. To address these problems, fluorescent nanodiamonds (FNDs), which exhibit infinite photostability and excellent biocompatibility, were explored as fluorophores in tracers for targeting VEGF receptors in growing tumors. To explore FND utility for imaging tumor VEGF receptors, we used click-chemistry to conjugate multiple copies of an engineered single-chain version of VEGF site-specifically derivatized with trans-cyclooctene (scVEGF-TCO) to 140 nm FND. The resulting targeting conjugates, FND-scVEGF, were then tested for functional activity of the scVEGF moieties through biochemical and tissue culture experiments and for selective tumor uptake in Balb/c mice with induced 4T1 carcinoma. We found that FND-scVEGF conjugates retain high affinity to VEGF receptors in cell culture experiments and observed preferential accumulation of FND-scVEGF in tumors relative to untargeted FND. Microspectroscopy provided unambiguous determination of FND within tissue by way of the unique spectral shape of nitrogen-vacancy induced fluorescence. These results validate and invite the use of targeted FND for diagnostic imaging and encourage further optimization of FND for fluorescence brightness.

Project description:Clinical development of anti-angiogenic agents has been a major landmark in cancer therapy for several types of cancers. Signals mediated by both vascular endothelial growth factor (VEGF) and bone morphogenetic protein (BMP)-9 and 10 have been implicated in tumor angiogenesis. However, previous studies have shown that targeting the individual signals was not sufficiently effective in retarding tumor growth in certain preclinical and clinical conditions. In the present study, we developed a novel decoy chimeric receptor that traps both VEGF and BMP-9/10. Single targeting of either VEGF or BMP-9/10 signals significantly reduced the formation of tumor vessels in a mouse xenograft model of human pancreatic cancer; however, it did not show significant therapeutic effects on tumor growth. In contrast, dual targeting of the angiogenic signals resulted in more significant inhibition of tumor angiogenesis, leading to delay of tumor growth. Our findings suggest that simultaneous blockade of VEGF and BMP-9/10 signals is a promising therapeutic strategy for the cancers that are resistant to anti-VEGF and BMP-9/10 therapies.

Project description:ObjectivesThis study quantified the change in blood pressure (BP) during antivascular endothelial growth factor (VEGF) tyrosine kinase inhibitor (TKI) therapy, compared BPs between TKIs, and analyzed change in BP during antihypertensive therapy.BackgroundTKIs targeting VEGF are associated with hypertension. The absolute change in BP during anti-VEGF TKI treatment is not well characterized outside clinical trials.MethodsA retrospective single-center study included patients with metastatic renal cell carcinoma who received anti-VEGF TKIs between 2007 and 2018. Mixed models analyzed 3,088 BPs measured at oncology clinics.ResultsIn 228 patients (baseline systolic blood pressure [SBP] 130.2 ± 16.3 mm Hg, diastolic blood pressure [DBP] 76.8 ± 9.3 mm Hg), anti-VEGF TKIs were associated with mean increases in SBP of 8.5 mm Hg (p < 0.0001) and DBP of 6.7 mm Hg (p <0.0001). Of the anti-VEGF TKIs evaluated, axitinib was associated with the greatest BP increase, with an increase in SBP of 12.6 mm Hg (p < 0.0001) and in DBP of 10.3 mm Hg (p < 0.0001) relative to baseline. In pairwise comparisons between agents, axitinib was associated with greater SBPs than cabozantinib by 8.4 mm Hg (p = 0.004) and pazopanib by 5.1 mm Hg (p = 0.01). Subsequent anti-VEGF TKI courses were associated with small increases in DBP, but not SBP, relative to the first course. During anti-VEGF TKI therapy, calcium-channel blockers and potassium-sparing diuretic agents were associated with the largest BP reductions, with decreases in SBP of 5.6 mm Hg (p < 0.0001) and 9.9 mm Hg (p = 0.007), respectively.ConclusionsAnti-VEGF TKIs are associated with increased BP; greatest increases are observed with axitinib. Calcium-channel blockers and potassium-sparing diuretic agents were associated with the largest reductions in BP.

Project description:In 2014, the survival benefits seen in REGARD and RAINBOW studies led the way for the regulatory approval of ramucirumab in the second line setting in oesophagogastric (OG) cancer. Trials of other drugs targeting the vascular endothelial growth factor (VEGF) pathway have met with mixed results but this remains an important pathway for evaluation in OG cancer. Perhaps the most interesting ongoing trials are those which target VEGF in combination with immunotherapy, which have a sound scientific rationale. Given the emerging role of immunotherapy in OG cancer, this is an important area of innovation. This review aims to outline targeting VEGF in OG cancer, the rationale behind the continued interest in this mechanism and possible future directions in combination with immunotherapy.

Project description:Placental growth factor (PlGF) remodels tumor vasculatures toward a normalized phenotype, which affects tumor growth, invasion and drug responses. However, the coordinative and spatiotemporal relation between PlGF and VEGF in modulation of tumor angiogenesis and vascular remodeling is less understood. Here we report that PlGF positively and negatively modulate tumor growth, angiogenesis, and vascular remodeling through a VEGF-dependent mechanism. In two independent tumor models, we show that PlGF inhibited tumor growth and angiogenesis and displayed a marked vascular remodeling effect, leading to normalized microvessels with infrequent vascular branches and increased perivascular cell coverage. Surprisingly, elimination of VEGF gene (i.e., VEGF-null) in PlGF-expressing tumors resulted in (i) accelerated tumor growth rates and angiogenesis and (ii) complete attenuation of PlGF-induced vascular normalization. Thus, PlGF positively and negatively modulates tumor growth, angiogenesis, and vascular remodeling through VEGF-dependent spatiotemporal mechanisms. Our data uncover molecular mechanisms underlying the complex interplay between PlGF and VEGF in modulation of tumor growth and angiogenesis, and have conceptual implication for antiangiogenic cancer therapy.

Project description:Development of neutralizing antibodies against biotherapeutic agents administered to prevent or treat various clinical conditions is a longstanding and growing problem faced by patients, medical providers and pharmaceutical companies. The hemophilia A community has deep experience with attempting to manage such deleterious immune responses, as the lifesaving protein drug factor VIII (FVIII) has been in use for decades. Hemophilia A is a bleeding disorder caused by genetic mutations that result in absent or dysfunctional FVIII. Prophylactic treatment consists of regular intravenous FVIII infusions. Unfortunately, 1/4 to 1/3 of patients develop neutralizing anti-FVIII antibodies, referred to clinically as "inhibitors," which result in a serious bleeding diathesis. Until recently, the only therapeutic option for these patients was "Immune Tolerance Induction," consisting of intensive FVIII administration, which is extraordinarily expensive and fails in ~30% of cases. There has been tremendous recent progress in developing novel potential clinical alternatives for the treatment of hemophilia A, ranging from encouraging results of gene therapy trials, to use of other hemostatic agents (either promoting coagulation or slowing down anti-coagulant or fibrinolytic pathways) to "bypass" the need for FVIII or supplement FVIII replacement therapy. Although these approaches are promising, there is widespread agreement that preventing or reversing inhibitors remains a high priority. Risk profiles of novel therapies are still unknown or incomplete, and FVIII will likely continue to be considered the optimal hemostatic agent to support surgery and manage trauma, or to combine with other therapies. We describe here recent exciting studies, most still pre-clinical, that address FVIII immunogenicity and suggest novel interventions to prevent or reverse inhibitor development. Studies of FVIII uptake, processing and presentation on antigen-presenting cells, epitope mapping, and the roles of complement, heme, von Willebrand factor, glycans, and the microbiome in FVIII immunogenicity are elucidating mechanisms of primary and secondary immune responses and suggesting additional novel targets. Promising tolerogenic therapies include development of FVIII-Fc fusion proteins, nanoparticle-based therapies, oral tolerance, and engineering of regulatory or cytotoxic T cells to render them FVIII-specific. Importantly, these studies are highly applicable to other scenarios where establishing immune tolerance to a defined antigen is a clinical priority.

Project description:Pharmacotherapies targeting vascular endothelial growth factor (VEGF) have revolutionized the management for neovascular retinal disorders including diabetic retinopathy and neovascular age-related macular degeneration. However, the burden of frequent injections, high cost, and treatment resistance in some patients remain unresolved. To overcome these challenges, newer generations of anti-angiogenic biological therapies, engineered proteins, implantable delivery systems, and biopolymers are currently being developed to enable more sustained, longer-lasting treatments. The use of gene therapies for pathologic angiogenesis has garnered renewed interests since the first FDA-approval of a gene therapy to treat inherited retinal diseases associated with biallelic RPE65 mutations. Newer generations of viral vectors and novel methods of intraocular injections helped overcome ocular barriers, improving the efficiency of transduction as well as safety profile. In addition, unlike current anti-VEGF gene therapy strategies which employ a biofactory approach to mimic existing pharmacotherapies, novel genome editing strategies that target pro-angiogenic factors at the DNA level offer a unique and distinct mechanistic approach that can potentially be more precise and lead to a permanent cure. Here, we review current anti-VEGF therapies and newer pharmacologic agents under development, examine technologies and progress in adapting anti-VEGF gene therapies, and explore the future application of CRISPR-Cas9 technology to suppress ocular angiogenesis.

Project description:The KDR gene, which participates in angiogenesis and lymphangiogenesis, produces two functionally distinct protein products, membrane-bound KDR (mbKDR) and its isoform, soluble KDR (sKDR). Since sKDR does not have a tyrosine kinase domain and does not dimerize, it is principally an antagonist of lymphangiogenesis by sequestering VEGF-C. Alternative polyadenylation of exon 30 or intron 13 leads to the production of mbKDR or sKDR, respectively, yet the regulatory mechanisms are unknown. Here we show that an antisense morpholino oligomer directed against the exon 13-intron 13 junction increases sKDR (suppressing lymphangiogenesis) and decreases mbKDR (inhibiting hemangiogenesis). The latent polyadenylation site in intron 13 of KDR is activated by blocking the upstream 5' splicing site with an antisense morpholino oligomer. Intravitreal morpholino injection suppressed laser choroidal neovascularization while increasing sKDR. In the mouse cornea, subconjunctival injection of the morpholino-inhibited corneal angiogenesis and lymphangiogenesis, and suppressed graft rejection after transplantation. Thus, this morpholino can be used for concurrent suppression of hemangiogenesis and lymphangiogenesis. This study offers new insight into the mechanisms and potential therapeutic modulation of alternative polyadenylation.

Project description:PurposeRepeated administration of anti-vascular endothelial growth factor drugs to treat age-related macular degeneration leads to resistance. To overcome this drawback, we developed the novel recombinant dual-targeting antibody fragment IDB0062, which is comprised of the anti-vascular endothelial growth factor A Fab and neuropilin 1-targeting peptide, and we assessed its properties.MethodsWe compared the in vitro activity of IDB0062 and conventional drugs using cell proliferation, wound healing, and Transwell assays. The in vivo efficacy of IDB0062 was determined using mouse choroidal neovascularization and oxygen-induced retinopathy models. To evaluate the ocular distribution of IDB0062, we intravitreally administered IDB0062 and ranibizumab to cynomolgus monkeys and measured the retinal drug levels.ResultsIDB0062 effectively inhibited not only vascular endothelial growth factor A in vitro but also placenta growth factor 2, vascular endothelial growth factor B, and platelet-derived growth factor BB, which induce vascular endothelial growth factor A-independent angiogenesis. In addition, IDB0062 showed non-inferior efficacy compared with aflibercept in vivo despite the low selectivity for mouse vascular endothelial growth factor A. In the monkey intravitreal pharmacokinetic study, IDB0062 improved drug distribution in the retina compared with ranibizumab, confirming the accelerated onset of pharmacological action when IDB0062 is injected in the vitreous humor.ConclusionsThrough neuropilin 1 binding, IDB0062 can improve the efficacy and accelerate the onset of pharmacological action in the posterior segment, which is targeted for macular degeneration, thereby improving drug responsiveness in drug-resistant patients.Translational relevanceConsidering its novel mechanism of action, IDB0062 may help in controlling resistance to conventional anti-vascular endothelial growth factor drugs in clinical settings.
