OWL's ESCRS 2023 event on Sunday, September 10, at 7 pm, promises an evening of visionary leadership and collaboration in ophthalmic innovation.

ESCRS 2023: OWL brings more of the 'world' to Ophthalmic World Leaders

The European Commission provided a positive opinion from the European Medicines Agency (EMA) Committee for Advanced Therapies, providing an Advanced Therapy Medicinal Product (ATMP) classification to OCU400 (Ocugen, Inc.). OCU400 is the first gene therapy from the biotechnology company to move forward into Phase 3 with a broad retinitis pigmentosa (RP) indication.

ATMP classification is given to medicines that allow for innovative opportunities for the treatment of disease, thus accelerating the regulatory review timeline of the new gene therapy. The classification will also allow for further collaboration between Ocugen and the EMA, with the EMA in place for scientific advice and protocol assistance as the company pushes for Marketing Authorisation Application (MAA) filing in 2026.

“Receiving ATMP classification is another significant milestone toward bringing OCU400 to the market in Europe,” said Shankar Musunuri, chairman, CEO and co-founder of Ocugen. “This designation makes it possible to stay on track with our clinical and commercial strategy and potentially provide this novel modifier gene therapy candidate to all RP patients in the United States and Europe by 2027.”

Besides the EMA, the FDA has also acknowledged that the Phase 3 trial of OCU400 can suffice for Biologics License Application (BLA) and MAA submissions. Ocugen, Inc. plans to file simultaneously in the US and Europe after completion of the trial.

Currently, the Phase 3 OCU400 trial is undergoing enrollment, and the study has a sample size of 150 participants. Patients 8 years old and older with early through late-stage advancement of RP are being recruited to take part in the study.

“We are encouraged by the EMA’s recognition of OCU400 as the Phase 3 liMeliGhT clinical trial advances,” Huma Qamar, chief medical officer at Ocugen, said. “I look forward to working collaboratively with the EMA to address the unmet medical need that remains for nearly 98% of the RP patient population.”

On 13 January, Teva Pharmaceuticals International GmbH, a subsidiary of Teva Pharmaceutical Industries Ltd., announced it would partner with Klinge Biopharma GmbH and Formycon AG in commercialising FYB203, Formycon’s biosimilar candidate to aflibercept (Eylea, Regeneron Pharmaceuticals Inc.) in designated regions of Europe.

 On 5 February, Formycon announced that Klinge Biopharma had also concluded an exclusive license agreement with Lotus Pharmaceutical.

 This new agreement will enable commercialisation of the product throughout the Asia-Pacific region. Pending regulatory approval, the product will be marketed under the brand name AHZANTIVE.

Under these agreements, Teva will lead the commercialisation effort in designated regions of Europe, excluding Italy, and in Israel. Lotus Pharmaceutical will lead commercialisation in Indonesia, Malaysia, the Philippines, Singapore, Taiwan, Thailand and Vietnam, as well as within the Special Administrative Region Hong Kong.

Previously, Teva was established as the European commercialisation partner of FYB201, Formycon's biosimilar to ranibizumab (Lucentis). Nicola Mikulcik, hief business officer of Formycon, commented on the expansion of the partnership. “With Teva, we are gaining a strong and proven partner for FYB203 in the major parts of Europe and Israel. Teva is already marketing our FYB201 ranibizumab biosimilar (Ranivisio/Ongavia) in Europe and can synergistically leverage an existing commercial infrastructure and well-established distribution channels in the ophthalmology field,” she said in the press release.

 “We are pleased to build on this trusted and successful collaboration. Particularly noteworthy is Formycon’s first-time responsibility for managing the entire commercial supply chain of the finished product.”

Like its reference product, the biosimilar FYB203 is an anti-vascular endothelial growth factor (VEGF) agent used to treat retinal disease. Chief among those indications is neovascular age-related macular degeneration (AMD), also known as wet AMD.

In November 2024, the European Medicines Agency's Committee for Medicinal Products of Human Use issued a positive recommendation for marketing authorisation of FYB203, under the brand names AHZANTIVE/Baiama. The European Commission is expected to announce a response to the authorisation application in late January 2025.

In June 2024, the US Food and Drug Administration (FDA) approved the biosimilar FYB203, also known as aflibercept-mrbb. In a press release at that time, the company stated3 that FDA approval was rooted in the company's “comprehensive data package” that included “analytical, pre-clinical, clinical and manufacturing data.” The data showed that FYB203 demonstrated comparable efficacy, safety, pharmacokinetics and immunogenicity to the reference product in patients with neovascular AMD.

Over the last 15 years, biosimilars have become a major feature of the health care landscape. Physicians in many disciplines, particularly oncology and immunology, have embraced biosimilars. However, access to educational resources on these powerful biologics can be inconsistent, and in turn, some ophthalmologists who could benefit from the adoption of biosimilars are left in the dark.

The real-world application of biosimilars was the focus of discussion for Martin Zinkernagel, MD, PhD, chair of the Department of Ophthalmology at the University Hospital of Bern, Switzerland, and Paolo Lanzetta, MD, professor of ophthalmology and chairman of the Department of Medicine-Ophthalmology at the University of Udine in Italy. In their discussion, the experts addressed several common questions, framed around the phase 3 clinical trial for biosimilar SB11 (BYOOVIZ) from Biogen. SB11 is approved in Europe and the United Kingdom. Like the reference product ranibizumab (Lucentis), SB11 is approved for the treatment of retinal disease including neovascular age-related macular degeneration (nAMD).

Addressing physicians’ levels of familiarity with biosimilars, Dr Lanzetta attributed much of the variation to regulatory discrepancies. “The uptake of biosimilars varies throughout Europe by country and by product,” he said. “Obviously, variation in the uptake of biosimilars [is] influenced by government involvement, reimbursement issues and tender procurement policies.” Recent survey data have revealed gaps in awareness across Europe and in the United States on the efficacy and safety of biosimilars for retinal diseases, Dr Lanzetta said, especially in terms of “real-world data.”

In a clinical application, Dr Lanzetta said, biosimilars may exhibit minor differences from the reference products, but they aren’t considered to have significant impact on the efficacy or safety profile. Typically, the biosimilar and reference medicine must have the same posology and route of administration, with few exceptions, he added.

Dr Lanzetta also said that in the last 10 years, the European Medicines Agency (EMA) has approved the highest number of biosimilars worldwide.

 “And this means, to us physicians, having both the possibility to have experience on their use in terms of safety and evaluating the efficacy after that,” he explained.

One common misconception about biosimilars is that these therapeutics are interchangeable with the idea of generic medicines. But there is a key indicator that biosimilars are unique: the cost. “While generic medicines are marketed at a significantly lower price than name brand ones, why do we not see the same level of cost savings with biosimilars?” Dr Zinkernagel asked.

Dr Lanzetta explained that biosimilars are developed via a rigorous, complex and highly regulated manufacturing process. “Generics are simple chemical medicines or agents, which is not the case for biosimilars and biologics,” he said. “Unlike generics, biologics, and therefore biosimilars as well, are very complex; they’re very difficult to copy. And the development processes are patented and proprietary to the originators.” The proprietary nature of biologic development, he added, is why biosimilars may have differences from their originators.

Prof Zinkernagel and Dr Lanzetta used data from the SB11 phase 3 trial to expand upon the capabilities of biosimilars. Prof Zinkernagel detailed the study: over 700 patients were included in the randomised, double-masked, parallel-group multicentre trial. Over 52 weeks, investigators evaluated the efficacy and the safety profile of this biosimilar SB11 in comparison with monthly ranibizumab for the treatment of nAMD.

“Patients with neovascular AMD were included, [with a] visual acuity range between 20/40 and 20/200,” Prof Zinkernagel said. “[Patients] were randomised in a 1:1 ratio to either have the originator or the biosimilar every 4 weeks from baseline up to week 48.”

Primary end-points were change from baseline in best corrected visual acuity at week 8 and change from baseline in central subfield thickness at week 4. The pre-specified secondary efficacy end-points included longer-term assessments of change from baseline in visual acuity, and the proportion of participants who lost fewer than 15 letters or who gained 15 or more letters in visual acuity from baseline at weeks 24 and 52.

“Other secondary end-points included, of course, change from baseline in central subfield thickness and central retinal lesion thickness at week 24, as well as change from baseline in choroidal neovascularisation [CNV] size and proportion of participants with active CNV leakage seen via OCT [optical coherence tomography] at week 24,” Prof Zinkernagel continued. Describing the results, he said, “When you look at the visual acuity improvements, it’s really equivalent. You have equivalence between the originator and the biosimilar, and the same holds true for a decrease in central retinal thickness. So the curves are basically the same, and also the secondary end-points.”

Prof Zinkernagel also spoke about the immunogenicity outcomes of the SB11 trial, as immunogenicity reactions have been a common problem in past assessments of anti–vascular endothelial growth factor (VEGF) agents. Along with detrimental effects to visual acuity, immunogenicity reactions can also lead to vasculitis and vitritis.

“Now, in this trial, the overall cumulative incidence of anti-drug antibodies, antibodies reacting against this specific drug up to week 52, was very low,” Prof Zinkernagel said. “For the SB11 biosimilar, it was 4.2%, and for the originator it was 5.5%. So very, very similar.”

He also noted that most antibodies were non-neutralising, which generally indicates a weak antibody response. “Furthermore, no statistical or clinically relevant differences in the incidence of anti-drug antibodies and neutralising antibodies were observed between treatment groups at any of the time points,” Prof Zinkernagel explained.

Dr Lanzetta highlighted the unique potentialities for anti-VEGF therapies as an area where physicians can consider treating patients with a biosimilar. “You can either switch a patient from the originator, obviously, or you can also consider treating with a biosimilar treatment-naive patients who may benefit…from being treated with that reference agent or originator agent,” he said. When to deploy a biosimilar will depend on many factors, including the locality where a patient is being treated. “Europe has different countries, different health care systems,” Dr Lanzetta said. “You may consider treating with the biosimilar patients who may not be strictly adherent to the cost of therapy and the frequency of treatment because of some cost issues.”

Just as education on biosimilars is vital to practitioners, awareness and education resources for patients are vital, too. “We spend a lot of time with our patients in letting them know that biologics did undergo a very rigorous approval process through studies, efficacy and safety studies,” Dr Lanzetta emphasised. This education is vital to getting patients on board with biosimilars, and it sparks enthusiasm about the potential benefits. “Once they do understand that, I think they will be very prone to receive a biosimilar; [it’s] in their interest and in the interest of the community, the whole community of patients, and in the interest of the health care system,” Dr Lanzetta said.

How biosimilars expand treatment options for patients with retinal disease

Marion Munk Euretina 2025

Marion Munk, a medical retina and uveitis specialist from Switzerland, introduced the International Retinal Imaging Society (IntRIS), a unique organization that brought together retina specialists, ophthalmologists, PhDs, and biomedical engineers. The society was dedicated to advancing retinal imaging through collaborative efforts. 

Munk highlighted the IntRIS symposium at the 2025 EURETINA annual meeting, which is taking place in Paris, France. The symposium featured several distinguished speakers who presented groundbreaking research. Giovanni Staurenghi discussed color autofluorescence. Phil Rosenfeld explored the impact of ocular perfusion on geographic atrophy progression. Srinivas Sadda presented on metabolic activity in RPE cells using adaptive optics fluorescein lifetime imaging. The symposium also included an overview of recommendation guidelines for fibrosis, focusing on development, quantification, and appropriate imaging modalities. 

Munk emphasized the society's unique approach, which brought together diverse specialists to provide comprehensive perspectives on medical challenges. A key strength of IntRIS was its collaborative model. Biomedical engineers worked closely with physicians to develop clinically relevant imaging technologies. This approach ensured that new devices addressed real-world medical needs and had potential market viability. The interdisciplinary nature of the group allowed for innovative thinking and novel approaches to understanding retinal diseases. 

Munk stressed the importance of ultra-widefield imaging and its potential to transform clinical decision-making. She noted that imaging technologies must go hand-in-hand with drug development, providing robust methods to quantify and visualize conditions like non-perfusion and fibrosis. The conversation highlighted the challenges in current imaging technologies, particularly in differentiating between various types of retinal tissue. Munk argued that as drug therapies advance, more sophisticated imaging techniques would become crucial for precise diagnosis and treatment monitoring. The IntRIS symposium represented a forward-thinking approach to retinal imaging, combining clinical expertise, technological innovation, and collaborative research to push the boundaries of medical understanding and treatment.

EURETINA 2025: Boris Stanzel, MD, methotrexate is rocking the European retina landscape

At this year's meeting of the European Society of Retina Specialists (EURETINA), Boris Stanzel, MD, presented results from two recent studies. Prof Stanzel is an attending physician at the Macula Centre, Knappschaft Eye Hospital Sulzbach, and a professor of ophthalmology at the University of Bonn, both in Germany. In a free paper presented on Saturday, 6 September, Prof. Stanzel discussed the use of intravitreal methotrexate in the preventing and treating proliferative vitreoretinopathy (PVR). In the speaker's corner that same day, he discussed new microperimetry findings and visual outcomes following implantation of an extended macular vision IOL for age-related macular degeneration (AMD).

Intravitreal methotrexate for PVR prophylaxis and treatment: Sulzbach pilot case series experience

"My world, in the moment, is rocked by methotrexate used intravitreally as an adjunct to PVR retinal detachment surgery," Prof Stanzel said. "We are presenting here at EURETINA...the first large European series. We have, right now, 22 patients in our readout who have at least 2 months follow-up to 3 years follow up." The outcomes were very successful, he noted. "Only one patient in this cohort of 22 eyes (of 22 patients) had a re-detachment, which was recognised at the point of oil removal and was therefore taken care of," Prof Stanzel said. "Methrotextrate is really an agent that makes a difference." The study findings also showed improved outcomes compared to studies in the US, which presented "only modest improvements in vision," he said, "but our European study had an improvement."

Extended macular vision IOL in macular atrophy: visual and microperimetry outcomes

Prof Stanzel also presented follow-up research findings on hyperaspheric IOL implantation in patients with macular atrophy secondary to AMD. The EyeMax Mono (Sharpview Ophthalmology Ltd.) was implanted in 21 eyes with small areas of geographic atrophy. "This is essentially a follow-up study report from last year. To a large extent, we have maintained the data that we have seen. There is a signficant benefit in patients who have an extrafoveal fixation, whereas the fixation area seems to predict the response in these patients, in terms of visual improvement." Watch the full video to hear Prof Stanzel explain why visual acuity is not necessarily the best marker to guide decisions for patients with geographic atrophy.
