Tumors induce their heterogeneous vasculature by secreting vascular endothelial growth factor (VEGF)-A. Anti-VEGF/VEGF receptor (VEGFR) drugs treat cancer, but the underlying mechanisms remain unclear. An adenovirus expressing VEGF-A (Ad-VEGF-A¹⁶⁴) replicates the tumor vasculature in mice without tumor cells. Mother vessels (MV) are the first angiogenic vessel type to form in tumors and after Ad-VEGF-A¹⁶⁴. Multiday treatments with a VEGF trap reverted MV back to normal microvessels. We now show that, within hours, a single dose of several anti-VEGF drugs collapsed MV to form glomeruloid microvascular proliferations (GMP), accompanied by only modest endothelial cell death. GMP, common in many human cancers but of uncertain origin, served as an intermediary step in MV reversion to normal microvessels. The vasodisruptive drug combretastatin CA4 also targeted MV selectively but acted differently, extensively killing MV endothelium. Antivascular changes were quantified with a novel Evans blue dye assay that measured vascular volumes. As in tumors, Ad-VEGF-A¹⁶⁴ strikingly increased endothelial nitric oxide synthase (eNOS) expression. The eNOS inhibitor N(G)-Nitro-l-arginine methyl ester mimicked anti-VEGF/VEGFR drugs, rapidly collapsing MV to GMP. Inhibition of eNOS reduces synthesis of its vasodilatory product, nitric oxide, leading to arterial contraction. Patients and mice receiving anti-VEGF/VEGFR drugs develop hypertension, reflecting systemic arterial contraction. Together, anti-VEGF/VEGFR drugs act in part by inhibiting eNOS, causing vasocontraction, MV collapse to GMP, and subsequent reversion of GMP to normal microvessels, all without extensive vascular killing.

OBJECTIVE:

To explore the feasibility of IGF2 imprinting system in target gene therapy for tumors.

METHODS:

The mouse H19 enhancer, DMD and promoter H19 were amplified by PCR from mouse genomic DNA and then cloned into the plasmid pDC312. The EGFP and DT-A fragments were amplified by PCR and cloned into the recombinant plasmid, and then the shuttle plasmid were transfected into HEK293 cells together with the adenoviral vector Ad5, namely, Ad-EGFP and Ad-DT-A. Adenovirus hexon gene expression was applied to confirm the presence of adenovirus infections. The effect of the IGF2 imprinting system was tested by fluorescence microscopy. RT-PCR and Western blotting after transfection of the recombinant adenoviral vectors into cancer cells were used to show loss of IGF2 imprinting (LOI) and maintenance of IGF2 imprinting (MOI), respectively. The anti-tumor effect was assessed by MTT and flow cytometry after the HCT-8 (LOI). Human breast cancer cell line MCF-7 (MOI) and human normal gastric epithelial GES-1 (MOI) cell line were transfected with Ad-DT-A in vitro. The anti-tumor effect was detected by injecting the Ad-DT-A in nude mice carrying HCT-8 tumors.

RESULTS:

The expression of EGFP protein, DT-A mRNA and DT-A protein were seen to be positive only in the HCT-8 tumor cell line. Infection with Ad-DT-A resulted in obviously growth inhibition in HCT-8 cells (75.4 ± 6.4)% compared with that in the control group, and increased the percentage of apoptosis in the HCT-8 cells (20.8 ± 5.9)%. The anti-tumor effect was further confirmed by injecting the recombinant adenoviruses in HCT-8 tumor-bearing nude mice, and the results showed that the Ad-DT-A inhibited the tumor growth, with on inhibition rate of 36.4%.

CONCLUSIONS:

The recombinant adenoviruses carrying IGF2 imprinting system and DT-A gene have been successfully constructed, while Ad-DT-A can effectively kill the tumor cells showing loss of IGF2 imprinting. It might play an important role in future target gene therapy against malignant tumors based on loss of IGF2 imprinting.

Inadequate vascularization limits the repair of bone defects. In order to improve angiogenesis and accelerate osteogenesis, the synergism of co-cultured cells with genetic modification in bone regeneration was investigated in this study. Endothelial progenitor cells (EPCs) and bone marrow stem cells (BMSCs) were transfected with the genes of vascular endothelial growth factor (VEGF) and bone morphogenetic protein 2 (BMP2) by adenovirus, respectively. The co-cultured cells, designated as four groups including BMSC + EPC, Ad-BMP2-BMSC + EPC, BMSC + Ad-VEGF-EPC, and Ad-BMP2-BMSC + Ad-VEGF-EPC groups, were seeded on an alginate gel and then implanted into rat intramuscularly to evaluate the effects on angiogenesis and osteogenesis. Both VEGF and BMP2 could induce the overexpression of inhibitor of DNA-binding 1(Id1) gene which significantly promoted tube formation in vitro and increase the amount of blood vessels in the Ad-BMP2-BMSC + Ad-VEGF-EPC group after implantation. Nevertheless, overexpression of Id1 retarded the terminal differentiation of osteoblasts and the bone formation. Later, osteogenic gene expression at transcriptional level, calcium nodules, and alkaline phosphatase (ALP) activity showed a gradual decrease and the amount of newly formed osteogenesis area exhibited a small increase in the Ad-BMP2-BMSC + Ad-VEGF-EPC group. This finding suggests that a balanced regulation of Id1 expression in VEGF-EPCs and BMP2-BMSCs may be critical to cell-based and gene-based approaches for bone regeneration.

Higher-dose Eylea gets swift US nod following recent CRL

The FDA has approved a higher-dose version of Regeneron Pharmaceuticals' Eylea (aflibercept) for patients with wet age-related macular degeneration (wAMD), diabetic macular oedema (DME) and diabetic retinopathy (DR). The decision marks a swift turnaround from June when the US regulator issued a complete response letter for Eylea 8mg citing an ongoing review of inspection at third-party manufacturer Catalent.The approval also comes on the heels of another FDA nod for a Regeneron drug – the C5 antibody branded Veopoz (pozelimab-bbfg) to treat CHAPLE disease. With Veopoz's approval, Regeneron hinted that a positive decision for Eylea 8mg could be forthcoming as pre-approval inspection issues that had led to the June CRL were now addressed.Regeneron said the latest clearance was based on 48-week results of the pivotal PULSAR and PHOTON trials. Last year, the company and partner Bayer reported that the primary endpoint was met in both Phase III trials – PULSAR in wet AMD and PHOTON in DME – with high-dose Eylea demonstrating non-inferior and clinically equivalent vision gains at 48 weeks with both 12- and 16-week dosing regimens, compared to an eight-week dosing regimen using the drug's original 2mg version.Regeneron noted that the vast majority of patients randomised at baseline to high-dose Eylea were able to maintain the 12- and 16-week dosing intervals through 48 weeks. The recommended dose for Eylea 8mg is monthly injections for the first three months across all indications, followed by every eight to 16 weeks in wAMD and DME, and every eight to 12 weeks for DR.The most common adverse reactions, occurring at a rate of ≥3%, in patients on the high-dose version of Eylea were cataract, conjunctival haemorrhage, higher intraocular pressure, ocular discomfort, blurred vision, vitreous floaters, vitreous detachment, corneal epithelium defect and retinal haemorrhage.Regeneron maintains exclusive rights to Eylea, including the high-dose version, while Bayer has licensed exclusive marketing rights outside of the US, where the companies share equally in profits from sales of the drug. Regulatory filings for Eylea 8mg are under review in Europe and Japan, with submissions also planned in other markets.Analysts have said an approval of the higher-dose version of Eylea could provide Regeneron a defence against rivals such as Roche's Vabysmo (faricimab-svoa), which won US approval early in 2022 to treat both wet AMD and DME. Roche's bispecific antibody, designed to block pathways involving Ang-2 and VEGF-A, allows less frequent dosing than standard therapy with Eylea 2mg.For related analysis, see Regeneron eyes key drug approval in Q3 and Physician Views Results: Ophthalmologist feedback shows Roche’s Vabysmo in rude health.

New clinical and real-world data for Roche’s Vabysmo at ASRS reveal improved outcomes for people with two leading causes of vision loss

Late-breaking post-hoc data indicate Vabysmo leads to less fibrosis, which may negatively impact vision, than aflibercept in people with diabetic macular edema (DME)Real-world data reinforce that first-line Vabysmo use improves outcomes and extends treatment intervals rapidly during the first four months for people with neovascular or ‘wet’ age-related macular degeneration (nAMD) and DMEClinical data reiterate Vabysmo’s positive anatomical outcomes, including reduced blood vessel leakage in the macula and greater and faster retinal fluid control Vabysmo is currently approved in over 70 countries to treat nAMD and DME, with more than one million doses distributed globally Basel, 20 July - Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that data from its ophthalmology portfolio will be highlighted in 25 abstracts at the 2023 American Society of Retina Specialists (ASRS) Annual Meeting, which will be held from 28 July to 1 August in Seattle, United States. The data further advance the depth of clinical and real-world evidence supporting the use of Vabysmo® (faricimab), the first and only bispecific antibody for the eye, for the treatment of neovascular or ‘wet’ age-related macular degeneration (nAMD) and diabetic macular edema (DME).1-14 “The clinical and real-world data at ASRS reinforce the improvement in outcomes brought by Vabysmo in two leading causes of vision loss, particularly new analyses suggesting that Vabysmo is associated with less vision-impacting fibrosis than aflibercept,” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “By improving disease control while offering a potentially less frequent treatment regimen, Vabysmo may help people spend less time managing their condition.” Vabysmo is currently approved in over 70 countries to treat nAMD and DME, with public reimbursement in over 20 markets and more than one million doses distributed globally.15 Neovascular AMD and DME are two leading causes of vision loss worldwide, affecting more than 40 million people.16-19 The following key data will be presented at ASRS 2023: Late-breaker: Vabysmo’s effect on epiretinal membrane (ERM) formation in DME compared to aflibercept Two-year post-hoc data from the YOSEMITE and RHINE phase III studies will be presented for the first time on ERM formation in DME patients, indicating Vabysmo leads to less retinal fibrosis than aflibercept.3 ERMs are fibrotic tissues on the surface of the retina, which may negatively impact the anatomy of the eye and compromise vision.20 Vabysmo drying and durability data Data will be presented reiterating positive anatomical outcomes previously seen with Vabysmo treatment, including reduced blood vessel leakage in the macula, and greater and faster retinal fluid control.4,6,7 Blood vessel leakage can cause a build-up of fluid and swelling in the back of the eye, contributing to sight loss.21,22 Data will also further support how increased intervals between doses of Vabysmo to treat nAMD and DME, compared to aflibercept, do not compromise outcomes.4,6,7 Vabysmo real-world data Roche’s expanding programme of real-world studies for Vabysmo includes more than 8,500 participants in almost 30 countries.15 Updates will be presented on real-world data from the FARETINA studies of Vabysmo in nAMD and DME looking at extended dosing intervals and impact on vision, including Vabysmo’s use as a first-line treatment.9,10 Preliminary data on early outcomes and treatment patterns in the United Kingdom FARWIDE studies of Vabysmo in nAMD and DME will be shared for the first time.11,12 In addition, independent investigator studies of Vabysmo are expected to be presented. The TRUCKEE study, which focused on real-world outcomes in people with nAMD across 14 sites in the United States is scheduled for presentation on 31 July during the Wet AMD Symposium 3 (1:38 PM to 1:44 PM PDT).23 Further information on select Roche abstracts that will be presented at ASRS 2023 can be found in the table below.

The programme includes AVONELLE-X, an extension study of TENAYA and LUCERNE evaluating the long-term safety and tolerability of Vabysmo in neovascular or ‘wet’ age-related macular degeneration (nAMD), and Rhone-X, an extension study of YOSEMITE and RHINE evaluating the long-term safety and tolerability of Vabysmo in diabetic macular edema (DME).28,29 In addition, Roche is investigating the efficacy and safety of Vabysmo in people with macular edema following retinal vein occlusion in two phase III studies, BALATON and COMINO.30,31 Roche has also initiated several phase IV studies, including the ELEVATUM study of Vabysmo in underrepresented patient populations with DME, the SALWEEN study of Vabysmo in a subpopulation of nAMD highly prevalent in Asia, as well as the VOYAGER study, a global real-world data collection platform.32-34 Roche also supports several other independent studies to further understand retinal conditions with a high unmet need.15 About Vabysmo® (faricimab)Vabysmo® (faricimab) is the first bispecific antibody approved for the eye.13,14 It targets and inhibits two signalling pathways linked to a number of vision-threatening retinal conditions by neutralising angiopoietin-2 (Ang-2) and vascular endothelial growth factor-A (VEGF-A).35,36 Ang-2 and VEGF-A contribute to vision loss by destabilising blood vessels, causing new leaky blood vessels to form and increasing inflammation.35,36 By blocking pathways involving Ang-2 and VEGF-A, Vabysmo is designed to stabilise blood vessels. Vabysmo is approved in over 70 countries around the world, including the United States, Japan, the United Kingdom and in the European Union for people living with neovascular or ‘wet’ age-related macular degeneration and diabetic macular edema.13-15,37,38 Review by other regulatory authorities is ongoing.

FDA Accepts Application for Genentech’s Vabysmo for the Treatment of Retinal Vein Occlusion (RVO)

Acceptance based on two Phase III studies that demonstrated early and sustained vision improvement with Vabysmo, meeting primary endpoint of non-inferiority compared to aflibercept Application was further supported by data showing Vabysmo achieved rapid and robust drying of retinal fluid If approved, RVO would be the third indication for Vabysmo in addition to wet age-related macular degeneration (AMD) and diabetic macular edema (DME) Vabysmo is currently approved in 60 countries to treat wet AMD and DME, with nearly one million doses distributed globally SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) has accepted the company’s supplemental Biologics License Application (sBLA) for Vabysmo® (faricimab-svoa) for the treatment of macular edema following retinal vein occlusion (RVO). The sBLA is based on results from the Phase III BALATON and COMINO studies that demonstrated treatment with Vabysmo provided early and sustained improvement in vision, meeting the primary endpoint of non-inferior visual acuity gains at 24 weeks compared to aflibercept. Vabysmo’s safety pro consistent with previous trials. “This acceptance brings us one step closer to delivering Vabysmo as a treatment for retinal vein occlusion, a disease that affects more than one million people in the United States and can cause severe and sudden vision loss,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “If approved, this would be the third indication for Vabysmo, the first bispecific antibody available for the treatment of retinal conditions that can cause blindness.” The data from the BALATON and COMINO studies will be submitted to other health authorities around the world, including the European Medicines Agency, for approval for the treatment of macular edema following RVO. The studies are ongoing, and data from weeks 24 to 72 will assess the potential of Vabysmo to extend dosing intervals up to every four months. Vabysmo is the first bispecific antibody approved for the eye and was approved in the United States for the treatment of wet, or neovascular, age-related macular degeneration (AMD) and diabetic macular edema (DME) in January 2022. Vabysmo is approved in 60 countries, including Japan, the United Kingdom, and in the European Union, for wet AMD and DME. Wet AMD, DME, and RVO together affect around three million people in the United States and are among the leading causes of vision loss. Vabysmo’s efficacy and safety pro wet AMD and DME is supported by four large, global studies involving more than 3,000 participants and extensive real world experience, with nearly one million doses distributed globally. Vabysmo is the only injectable eye medicine approved for wet AMD and DME by the U.S. Food and Drug Administration (FDA) with the option for treatments from one to four months apart in the first year following four initial monthly loading doses, based on evaluation of the patient’s anatomy and vision outcomes. It targets and inhibits two disease pathways linked to a number of vision-threatening retinal conditions by neutralizing angiopoietin-2 (Ang-2) and vascular endothelial growth factor-A (VEGF-A). About the BALATON and COMINO Studies BALATON (NCT04740905) and COMINO (NCT04740931) are two randomized, multicenter, double-masked, global Phase III studies evaluating the efficacy and safety of Vabysmo®️ (faricimab-svoa) compared to aflibercept. For the first 20 weeks, patients are randomized 1:1 to receive six monthly injections of either Vabysmo (6.0 mg) or aflibercept (2.0 mg). From weeks 24 to 72, all patients receive Vabysmo (6.0 mg) up to every four months – according to a personalized treatment interval dosing regimen – using a treat-and-extend approach. The BALATON study is being conducted in 553 patients with branch retinal vein occlusion. The COMINO study is being conducted in 729 patients with central retinal or hemiretinal vein occlusion. The primary endpoint of each study is the change in best-corrected visual acuity (BCVA) from baseline at 24 weeks. Secondary endpoints include change in central subfield thickness (CST) from baseline over time up to 24 weeks. Both studies met their primary endpoint, with Vabysmo showing non-inferior visual acuity gains compared to aflibercept. The average vision gains from baseline were comparable between the two treatments in both studies. In BALATON, vision gains were +16.9 eye chart letters in the Vabysmo arm and +17.5 letters in the aflibercept arm at 24 weeks. In COMINO, vision gains were +16.9 letters in the Vabysmo arm and +17.3 letters in the aflibercept arm at 24 weeks. A secondary endpoint showed that Vabysmo achieved rapid and robust drying of retinal fluid, as measured by reduction in CST from baseline. In both studies, reductions in CST were comparable across treatment arms. In BALATON, CST reductions from baseline at 24 weeks were 311.4 μm in the Vabysmo arm and 304.4 μm in the aflibercept arm. In COMINO, CST reductions from baseline at 24 weeks were 461.6 μm in the Vabysmo arm and 448.8 μm in the aflibercept arm. Additionally, both studies showed that more Vabysmo patients had an absence of blood vessel leakage in the retina compared to aflibercept patients as seen in a pre-specified exploratory endpoint. Blood vessel leakage in the macula may lead to more retinal fluid, which can cause swelling and blurry vision. In BALATON, one-third of patients (34%) treated with Vabysmo had an absence of macular leakage compared to one-fifth (21%) of aflibercept patients at 24 weeks. In COMINO, the rates were 44% for Vabysmo patients versus 30% for aflibercept patients at 24 weeks. In both studies, Vabysmo’s safety pro consistent with previous trials. The most common adverse reaction was conjunctival hemorrhage (3%). Safety results were consistent across study arms. The studies are ongoing, and data from weeks 24 to 72 will assess the potential of Vabysmo to extend dosing intervals up to every four months. About Retinal Vein Occlusion Retinal vein occlusion (RVO) is the second most common cause of vision loss due to retinal vascular diseases. It affects more than one million people in the U.S., mainly those aged 50 or older, and can lead to severe and sudden vision loss. RVO typically results in sudden, painless vision loss in the affected eye because the vein blockage restricts normal blood flow in the affected retina, resulting in ischemia, bleeding, fluid leakage, and retinal swelling called macular edema. Currently, macular edema due to RVO is typically treated with repeated intravitreal injection of anti-vascular endothelial growth factor therapies. There are two main types of RVO: branch retinal vein occlusion (BRVO), which affects an estimated 887,000 people in the U.S. and occurs when one of the four smaller “branches” of the main central retinal vein becomes blocked; and central retinal vein occlusion (CRVO), which is less common, affecting an estimated 265,000 people in the U.S., and occurs when the eye’s central retinal vein becomes blocked. About the Vabysmo® (faricimab-svoa) Clinical Development Program Genentech has a robust Phase III clinical development program for Vabysmo. The program includes AVONELLE-X, an extension study of TENAYA and LUCERNE evaluating the long-term safety and tolerability of Vabysmo in wet, or neovascular, macular degeneration (AMD), and RHONE-X, an extension study of YOSEMITE and RHINE evaluating the long-term safety and tolerability of Vabysmo in diabetic macular edema (DME). In addition, Genentech is investigating the efficacy and safety of Vabysmo in people with macular edema following retinal vein occlusion (RVO) in two Phase III studies, BALATON and COMINO. Genentech has also initiated several Phase IV studies, including the Elevatum study of Vabysmo in underrepresented patient populations with DME, the SALWEEN study of Vabysmo in a subpopulation of wet AMD highly prevalent in Asia, as well as the VOYAGER study, a global real-world data collection platform. About Vabysmo® (faricimab-svoa) Vabysmo (faricimab-svoa) is the first bispecific antibody approved for the eye. It targets and inhibits two disease pathways linked to a number of vision-threatening retinal conditions by neutralizing angiopoietin-2 (Ang-2) and vascular endothelial growth factor-A (VEGF-A). While research is underway to better understand the role of the Ang-2 pathway in retinal disease, Ang-2 and VEGF-A are thought to contribute to vision loss by destabilizing blood vessels, which may cause new leaky blood vessels to form and increase inflammation. By blocking pathways involving Ang-2 and VEGF-A, Vabysmo is designed to stabilize blood vessels. Vabysmo U.S. Indications Vabysmo (faricimab-svoa) is a prescription medicine given by injection into the eye, used to treat adults with neovascular (wet) age‑related macular degeneration (AMD) and diabetic macular edema (DME). Important Safety Information Contraindications Vabysmo is contraindicated in patients who have an infection in or around their eye, have active swelling around their eye that may include pain and redness, or are allergic to Vabysmo or any of the ingredients in Vabysmo. Warnings and Precautions Injections like the one for Vabysmo can cause an eye infection (endophthalmitis) or separation of layers of the retina (retinal detachment). Patients should seek medical care if they experience increasing eye pain, vision loss, sensitivity to light, or redness in the white of the eye. Vabysmo may cause a temporary increase in pressure in the eye (intraocular pressure), which occurs 60 minutes after the injection. Although not common, Vabysmo patients have had serious, sometimes fatal, problems related to blood clots, such as heart attacks or strokes (thromboembolic events). In clinical studies for wet AMD during the first year, 7 out of 664 patients treated with Vabysmo reported such an event. In DME studies from baseline to week 100, 64 out of 1,262 patients treated with Vabysmo reported such an event. Adverse Reactions The most common adverse reactions (≥5%) reported in patients receiving Vabysmo were cataract (15%) and blood on the white of the eye (conjunctival hemorrhage, 7%). These are not all the possible side effects of Vabysmo. Pregnancy, Lactation, Females and Males of Reproductive Potential Based on how Vabysmo interacts with your body, there may be a potential risk to an unborn baby. Patients should use birth control before their first injection, during their treatment with Vabysmo, and for 3 months after their last dose of Vabysmo. It is not known if Vabysmo passes into breast milk. Patients should talk to their healthcare provider about the best way to feed their baby if they receive Vabysmo.
