The pan-Canadian Pharmaceutical Alliance engaged the Canadian Agency for Drugs and Technologies in Health to lead a multiphase stakeholder consultation process to encourage biosimilar uptake.

Given the availability of biosimilars of infliximab, etanercept, and adalimumab in multiple markets worldwide, and given the cost savings associated with the biosimilars, there is growing interest in switching patients receiving maintenance treatment for uveitis to these biosimilar options, but data in switching patients with uveitis have been limited.

The field of biosimilar contenders for anti–vascular endothelial growth factor (anti-VEGF) therapies is taking shape, with biosimilar developer Coherus seeking to launch its ranibizumab biosimilar in 2021 and Samsung Bioepis having reached a commercialization agreement for 2 biosimilar anti-VEGFs of its own. Last week, a study published in JAMA Ophthalmology supported the use of anti-VEGF agents in wet age-related macular degeneration (AMD), saying that, though these drugs are costly, they may provide substantial economic value to both patients and society.

Researchers report that there were no differences in visual acuity letter score (VALS) and central subfield thickness (CST) outcomes at month 24 between patients treated with bevacizumab and those treated with aflibercept in the SCORE2 study.

Samsung Bioepis announced Wednesday that it has entered into a new commercialization agreement with partner Biogen for 2 ophthalmology biosimilars that are currently in development.

Even as biosimilars of anti–vascular endothelial growth factor (anti-VEGF) agents are coming to market and advancing through the pipeline, a new agent that may have substantial benefits for patients with wet age-related macular degeneration (AMD) has been approved by the FDA: brolucizumab, which sponsor Novartis will sell as Beovu.

Vial sharing for bevacizumab that would otherwise have been discarded yielded a 97.88% reduction in the total cost of a single year of intravitreal injections, as well as a 96.54% increase in the number of injections performed.

Treating macular edema associated with central retinal vein occlusion (CRVO) with aflibercept was noninferior to ranibizumab treatment at 100 weeks, while the results for bevacizumab versus ranibizumab were inconclusive.

Regeneron’s aflibercept (Eylea) has been approved by the FDA for a prefilled syringe (PFS) presentation. The 2-mg, single-dose, PFS will offer the greater ease of use less preparation than the vial presentation of the drug used to treat a range of eye disorders.

Novartis, developer of the brand-name Lucentis, announced on Friday that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has granted the drug a positive opinion for the treatment of retinopathy of prematurity in infants.

A secondary post hoc analysis of patients who had neovascular age-related macular degeneration (AMD) and were treated with intravitreal aflibercept or ranibizumab—2 widely used anti-vascular endothelial growth factor (anti-VEGF) therapies—found that those with certain characteristics had a substantial risk of conversion to AMD in the untreated eye.

Anti–vascular endothelial growth factor therapy is the standard of care for the first-line treatment of macular edema associated with central retinal vein occlusion or hemiretinal vein occlusion, and a number of therapeutic options are available, including aflibercept, ranibizumab, and off-label bevacizumab.

The FDA this week approved Regeneron’s aflibercept (Eylea) to treat all stages of diabetic retinopathy. The regulatory decision makes aflibercept the only anti–vascular endothelial growth factor therapy approved for 2 dosing regimens in this indication: every 8 weeks or every 4 weeks.

During this week’s Association for Research in Vision and Ophthalmology 2019 Annual Meeting, researchers presented new findings on the utility—and the delivery—of bevacizumab in eye disorders.

Xbrane Biopharma, a Swedish biotechnology company, says it is starting its phase 3 trial of its ranibizumab biosimilar, referencing Lucentis, and also set sales targets for the treatment for patients with wet age-related macular degeneration.

Republic of Korea-based biosimilar developer Alteogen has reported that it has been granted a process patent for its method of producing an aflibercept biosimilar, ALT-L9, referencing Regeneron’s innovator drug Eylea.

Swedish biotechnology company Xbrane Biopharma recently announced that it has submitted its first national Clinical Trial Application to the FDA seeking permission to begin the Xplore trial.

This month, the Court of Justice of the European Union ruled that Italy’s national health system can reimburse for the use of bevacizumab in the treatment of eye diseases, such as age-related macular degeneration, despite the fact that bevacizumab does not have a marketing authorization for this indication.

According to the earnings report, aflibercept sales in the United States increased 7% to $1.02 billion versus third quarter 2017 results.

Swedish biotechnology company Xbrane Biopharma today announced that its ranibizumab biosimilar, referencing Lucentis, demonstrated an equivalent pharmacokinetic (PK) profile and equivalent tolerability to its reference in an in vivo study.

A United Kingdom court has ruled in favor of the National Health Service, allowing the health system to provide intravitreal injections of the anti–vascular endothelial growth factor agent bevacizumab to patients with age-related macular degeneration (AMD).

The updated treatment approach will allow clinicians, based on individual patients’ outcomes, to lengthen the intervals between injections for patients with neovascular age-related macular degeneration (AMD) who are already in the first year of treatment. That could mean fewer injections and fewer trips to the clinic for patients with AMD.

Because tumor necrosis factor plays a role in most neurodegenerative diseases of the eye, and because etanercept has shown promise in improving recovery of injured facial nerves, authors of a recent study sought to determine whether etanercept can be used to protect retinal ganglion cells and improve visual outcomes after injury.

In India, Razumab, manufactured by Intas Pharmaceuticals, was approved as a similar biologic to ranibizumab in 2015; the retrospective study RE-ENACT collected data and analyzed the effectiveness of this biosimilar product in the real-world setting in patients with age-related macular degeneration, diabetic macular edema, and retinal vein occlusion (RVO).

Eales disease (ED) is a common, idiopathic, inflammatory retinal vasculitis that particularly affects young adults. Current treatments available for ED include corticosteroids, laser photocoagulation, retinal cryotherapy, and surgery, but a recent study found that using intravitreal bevacizumab injections may produce better outcomes and reduce the need for surgery.

In a new paper, researchers sought to describe how much the European Union is overspending on neovascular age-related macular degeneration treatment by relying on ranibizumab and aflibercept rather than bevacizumab in ophthalmology.

Data suggest that intravitreal bevacizumab increases the risk of thromboembolism, and some studies have raised the possibility of a link between bevacizumab and myocardial infarction (MI), while other studies did not find such a relationship.

Last week, an overview of systematic reviews and meta-analyses investigating systemic adverse events associated with intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatments was published in JAMA Ophthalmology.

One week after intravitreal bevacizumab injection, corneal endothelial cells showed no sign of inflammation or any other complications, according to a study published in BMC Ophthalmology.

While corticosteroids are a common treatment for uveitis, effective corticosteroid-sparing therapies are necessary to maintain disease control without risking corticosteroid-related adverse events.
