Age-related macular degeneration (AMD), one of the leading causes of blindness among elderly Americans. Wet AMD, its advanced form, results from abnormal blood vessels that leak and swell the retina and causes vision loss.

NEI team’s research found that AMD decreases docosahexaenoic acid production in retinal peripheries, leading to decreased formation of protective molecules known as elovanoids which help prevent uncompensated stress in eyes which leads to macular degeneration.

Aflibercept

aflibercept is an anti-vascular endothelial growth factor (VEGF) monoclonal antibody used to treat wet age-related macular degeneration, administered as an eye injection on an ongoing basis. Studies have demonstrated its efficacy at improving visual acuity and slowing vision loss; it also delays progression of disease while being well tolerated by patients.

Wet macular degeneration occurs when abnormal blood vessels form beneath the retina (a thin layer of cells at the back of the eye). When these blood vessels leak and damage to macula (the central region of retina that helps us see fine details clearly), wet macular degeneration can quickly lead to rapid and significant loss of central vision if left untreated. Treatment for wet macular degeneration involves destroying abnormal blood vessels to stop further leakage or further macula damage; wet macular degeneration treatment usually involves destroying abnormal blood vessels to stop leakage or prevent further macula damage; damage as quickly as possible to prevent further macula damage caused by wet macular degeneration can quickly lead to rapid and significant loss of central vision over time; treatments typically include destroying abnormal blood vessels to prevent leakage while protecting macula from further damage; otherwise rapid central vision loss could occur rapidly or significant loss could occur. Treatment for wet macular degeneration typically involves destroying any abnormal blood vessel leakage while protecting macula damage can be treated successfully by destroying abnormal vessels to stop further leakage as well as protect macula damage occurring further down. For this condition requires destruction of abnormal blood vessels to protect macula damage occurring further damage occurring; when left untreated it could result in rapid and significant loss. If left untreated then severe central vision loss occur quickly leading to rapid and significant loss. For this condition requires treating abnormal blood vessel destruction to stop further leakage will occur quickly leading to rapid loss; treatment usually includes destruction of abnormal vessels to protect macula by way of other forms destroying them in order to stop leakage damage before further leakage damage occurring within an image damage by means of further leakage from further leakage/damage damages before further leakage/damages occurring preventing leakage/damages damage occurring by degeneration can result in significant loss; treatment involves destruction as this could potentially leading to loss. If left untreated may require significant loss in central vision loss rapid loss through treatment by degeneration could potentially leading to rapid loss. Treatment requires either way destruction for wet degeneration to occur and further damaging macula destruction as soon as well to damage occur preventing leakage or otherwise damage occurring and stopping further leakage to take place thus prevent leakage/damages occurring thus stopping further leakage thus protecting macula thus further leakage damage occurring through which in turn off and protect maula’s further leakage damage occurs for further damaging happening thus further loss thereby stopping leakage so to potential loss; otherwise leads rapidly or simply losing central vision loss occurring later leading to begin; with destruction being destroyed may lead to result requiring removal.

In the phase 3 VIEW 1 and 2 trials, Aflibercept achieved similar anatomic and visual outcomes as EYLEA for patients suffering from subfoveal CNV due to wet age-related macular degeneration; however, PBAC concluded there was insufficient evidence showing its superiority over Ranibizumab.

The phase 2 CANDELA clinical trial found that Aflibercept 8 mg led to greater proportions of eyes with no fluid in their central subfield at 16 weeks than Aflibercept 2 mg did, yet this difference was not statistically significant. Furthermore, its safety profile was comparable with EYLEA with no cases of retinal vasculitis, occlusive retinitis or endophthalmitis occurring across either trial.

Aflibercept is available with a valid prescription from your ophthalmologist and should be used accordingly. Injection frequency will depend on individual needs; any questions or concerns should be directed toward them directly.

At Bayer and Regeneron’s aflibercept development team’s Pediatric Bioethics Board Advisory Committee (PBAC), researchers found the drug to be both efficacious and safe and well tolerated among children, earning approval as part of an overall treatment plan to address wet age-related macular degeneration. BEOVU will soon become available as an injection into the eye to treat wet macular degeneration; Bayer developed it.

Faricimab-svoa

Faricimab-svoa (Vabysmo — Genentech) was recently approved by the Food and Drug Administration as an injectable treatment for macular edema caused by retinal vein occlusion. It’s a first-in-class ophthalmic biologic agent designed to inhibit two disease pathways associated with age-related macular degeneration: angiopoietin-2 (Ang-2) and vascular endothelial growth factor A (VEGF-A). Blocking both pathways helps stabilize blood vessels while decreasing fluid leakage; according to company it provides safe and effective therapy for diabetic macular edema (DME), it will become available commercially in 2023.

The agency made their decision based on positive findings from phase 3 BALATON and COMINO studies, both global randomized double-masked randomized studies that compared faricimab-svoa to aflibercept in terms of changes to best corrected visual acuity over 24 weeks, as well as reductions in central subfield thickness reduction and drying up retinal fluid.

Faricimab-svoa outperformed aflibercept in both studies by providing faster and more robust drying of retinal fluid than was possible with its predecessor; this led to quicker increases in best corrected visual acuity than its counterpart; it also had an excellent safety profile, leading to less side effects and injections with each trial of faricimab-svoa than had occurred under its predecessor’s management.

DME (Diabetes Mellitus Exacerbation) is a progressive eye condition affecting over one million Americans over 50. It is the second-leading cause of vision loss due to retinal vascular diseases and can result in serious loss of vision in those afflicted. Treatment typically entails repeated intravitreal injections of anti-vascular endothelial growth factor drugs for anti-vascular endothelial growth factor drugs, though some patients may require multiple sessions.

However, daily injections may cause undue patient discomfort and require continuous administration. To address this, researchers are creating new therapeutic agents to extend the time between injections. A study by the DRCR Retina Network concluded that patients treated regularly and consistently with pegcetacoplan had reduced frequency of injections as well as improved visual acuity over time.

The AREDS formula, consisting of zinc and vitamins C and E, was created to help lower risk of vision loss among those diagnosed with wet AMD. It is available as a generic formulation that may be administered directly by physicians as a preservative-free liquid suspension suspension.

BEOVU

BEOVU (brolucizumab) was approved to treat wet macular degeneration by Novartis and was made available to patients beginning October 2019. As the first bispecific antibody ever used to treat macular degeneration, BEOVU can block both vascular endothelial growth factor A and angiogenic factor-2 simultaneously for maximum effectiveness, potentially prolonging vision retention by less frequent injections allowing longer lasting vision preservation for longer.

Wet AMD occurs when blood vessels proliferate and leak fluid into the eye, damaging macula cells and blurring vision – potentially leading to permanent blindness. It’s called wet macular degeneration due to these wet blood vessels being considered wet; treatment options include medications which block this growth – beovu is an anti-VEGF medication administered through injection via syringe; however, this medicine requires prior approval and must only be administered by qualified healthcare practitioners.

Beovu contains an anti-vascular endothelial growth factor monoclonal antibody which targets this protein, which leads to blood vessel growth in the retina, leading to fluid buildup and macular oedema as well as inflammation within retinal cells. Two trials conducted over two years with patients suffering from wet macular degeneration tested its efficacy against an existing treatment option called Aflibercept.

Both studies demonstrated that Beovu was as effective as Aflibercept in lowering risk of advanced AMD progression and improving visual acuity, and also at decreasing fluid leakage from retina.

However, since Beovu was approved, reports of severe side effects have surfaced. Retinal specialists have warned of its potential to cause occlusive vasculitis and retinal artery occlusion – rare but possible symptoms; thus the FDA requested Novartis provide additional data regarding its safety; Novartis maintains it is safe and stands by their data submitted before approval; additionally they will establish an external safety committee to review cases associated with Beovu use.

Lucentis

Lucentis is an anti-VEGF injection designed to slow vision loss in patients suffering from wet age-related macular degeneration (wet AMD). It works by blocking vascular endothelial growth factor (VEGF), which encourages blood vessels to dilate and leak fluid into the eye, as well as stopping new vessels from sprouting which could further damage macula tissue. When administered via direct eye injection, this medication usually shows positive results for most individuals.

Recent research on ranibizumab biosimilar SB11 provides further evidence of its effectiveness in treating wet macular degeneration. According to results published in the British Journal of Ophthalmology, it shows similar efficacy, safety, immunogenicity and pharmacokinetics as its reference brand Lucentis; further supporting biosimilarity ratified between them.

Biosimilars are an emerging sector of the pharmaceutical industry with potential to reduce healthcare costs. Many companies are producing biosimilar versions of existing drugs to save on manufacturing and marketing expenses; the FDA has already approved several biosimilar versions, including Lucentis.

Pre-filled syringes designed specifically to use with Lucentis 0.5 mg vial will make drug administration simpler for physicians. They will become available early next year. According to the company, these new syringes will make dosing simpler. These devices are approved to treat wet macular degeneration, macular edema following retinal vein occlusion, and myopic choroidal neovascularization among other conditions.

Retinal and choroidal vascular diseases are leading causes of blindness worldwide, often creating significant socioeconomic burdens for both patients and their families. There are emerging therapies designed to decrease disease burden while also protecting sight preservation. Clinical trials have proven the efficacy of anti-VEGF therapies over standard care; however, due to high treatment burden and low adherence levels they cannot provide maximum benefits; therefore it is imperative that new therapies that address this challenge be developed; several of which currently in development include expanded therapeutic targets and innovative delivery mechanisms with longer durability so as to reduce treatment burden and ease treatment burden over time.
