Opthea look to transform standard of care treatment for wet AMD to improve vision outcomes
\nTwo Phase 3 trials are underway investigating lead drug OPT-302 with results from both forecast mid 2025
\nOpthea looking to be first drug statistically to improve vision for sufferers of wet AMD since launch of LUCENTIS in 2006<\/p>\n
Retinal diseases focused biotech Opthea (ASX:OPT)<\/a> is looking to provide the biggest improvement to standard of care in almost 20 years for wet age-related macular degeneration (wet AMD), a leading cause of blindness in the aged population.<\/p>\n OPT recently announced completion of patient enrolment<\/a> in its first pivotal Phase 3 trial (COAST) investigating sozinibercept (OPT-302), a vascular endothelial growth factor (VEGF)-C\/D inhibitor in combination with aflibercept, an anti-VEGF-A therapy, for the treatment of wet AMD.<\/p>\n The clinical program for OPT-302 comprises two Phase 3 pivotal trials, COAST and ShORe, with ShORe\u2019s enrolment forecast to conclude in Q2 CY24. OPT plans to release topline results from both trials by mid-2025.<\/p>\n Stockhead<\/em> this week caught up with OPT\u2019s US-based management team visiting Australia,\u00a0as it looks to disrupt the eye disease treatment landscape. CEO Dr Frederick Guerard and CFO Peter Lang both joined the biotech in October 2023,\u00a0 <\/p>\n Guerard boasts a pharmaceutical career exceeding 25 years. He was the Graybug Vision CEO, overseeing the clinical development of a late-stage wet AMD product and orchestrating its merger with CalciMedica, where he continues as a non-executive board member.<\/p>\n Guerard was also the worldwide business franchise head of ophthalmology at Novartis.\u00a0 Along with holding various leadership roles at the multinational pharmaceutical company he also played a key role in revitalising the product pipeline through strategic acquisitions and licensing transactions in areas such as dry eye, presbyopia, and inherited retinal diseases.<\/p>\n Lang has more than 25 years of experience in strategic, operational, and financial solutions with extensive expertise in healthcare and biopharmaceuticals. His leadership spans roles in biopharmaceutical companies and renowned global and boutique investment banks.<\/p>\n Before joining OPT, Lang was CFO of Aerie Pharmaceuticals, where he played a key role in the successful strategic and financial repositioning of the company, leading to its acquisition by Alcon AG for ~US$950 million.<\/p>\n He was MD and partner at Ridge Advisory and has held leadership roles in healthcare investment banking at HSBC, Bank of America Merrill Lynch, UBS Investment Bank, and Leerink Partners.<\/p>\n \u00a0<\/p>\n First a little background on AMD. There are two types of AMD \u2013 wet and dry<\/a>. Dry AMD happens when the macular gets thinner with age in three stages including early, intermediate, and late.<\/p>\n Wet AMD is a less frequent form of late-stage dry AMD typically leading to accelerated vision deterioration.<\/p>\n Guerard says wet AMD happens when abnormal blood vessels grow in the back of the eye and damage the macula, usually causing faster vision loss.<\/p>\n \u201cIt forms for reasons we don\u2019t know and distorts the vision,\u201d he says.<\/p>\n \u201cPatients wake up in the morning and they have a black spot in the middle of their vision and if not treated early and aggressively with existing standard of care patients will go blind.<\/p>\n \u201cIt\u2019s very impactful because sufferers lose the centre of their vision so they can\u2019t drive a car or even see their family properly.\u201d<\/p>\n He says thankfully medications have been developed to address wet AMD but what OPT aims to do is add in their drug to existing treatments for better vision outcomes.<\/p>\n \u00a0<\/p>\n In technical terms OPT-302 is a soluble form of vascular endothelial growth factor receptor 3 (VEGFR-3) expressed as an immunoglobulin G1 (IgG1) Fc-fusion protein. It is injected into the eye, along with current treatments for wet AMD.<\/p>\n OPT-302 binds and neutralises the activity of VEGF-C and VEGF-D on their endogenous receptors, VEGFR-2 and VEGFR-3.<\/p>\n Studies show that blocking VEGF-C and VEGF-D can inhibit the growth of blood vessels and prevent vascular leakage, addressing key factors in the pathophysiology of retinal diseases, including wet AMD.<\/p>\n \u201cIt\u2019s an injection you get on a regular basis, which could be as often as every four, eight or 20 weeks depending on the patient,\u201d Guerard says.<\/p>\n OPT\u2019s Phase 2b trial demonstrated met its pre-specified primary efficacy endpoint of a statistically significant improvement in visual acuity for patients treated with OPT-302 combined with standard of care LUCENTIS (ranibizumab) compared to ranibizumab alone.<\/p>\n Furthermore, secondary outcomes also included an increase in participants experiencing gains of 10 or more letters in vision, improved anatomy marked by reduced swelling and vascular leakage, all while maintaining a favourable safety profiles.<\/p>\n \u00a0<\/p>\n Guerard says there are currently 3.5 million patients with wet AMD between the US, Europe, Australia and Canada receiving treatment who could all benefit fom OPT-302.<\/p>\n \u201cOur drug could provide additional benefit to all these patients around the world,\u201d he says.<\/p>\n \u201cIt\u2019s a very, very large market and\u00a0 we estimated the sales of existing drugs in the wet AMD segment at over US$10bn for last year.<\/p>\n \u201cWe are not competing with any of these drugs but will be added to these drugs so the prospect for the investor is what we see as the biggest revolution in the quality of care of these patients in almost 20 years.\u201d<\/p>\n He says no drug on the market today has delivered better vision acuity than LUCENTIS,\u00a0 which was approved by the FDA<\/a> for wet AMD in 2006.<\/p>\n \u201cThat drug was a revolution and transformed the life of millions of patients by allowing them to see better and for longer,\u201d he says.<\/p>\n \u201cBut of course what we are trying to do here is do better by combining another mechanism of action on top of LUCENTIS and that would be the first time in almost 20 years that a company has demonstrated better visual outcomes for the patients.\u201d<\/p>\n Lang says subsequent drugs have also been launched since LUCENTIS but not improving visual acuity.<\/p>\n \u201cThere are other drugs which have been developed and approved like Eylea which reduce the number of injections that patients receive every year but they don\u2019t improve vision,\u201d he says.<\/p>\n OPT-302 is designed to work alongside these drugs and not aimed at replacing them.<\/p>\n \u201cWe are trying to be the first drug to improve vision statistically,\u201d\u00a0 Lang says.<\/p>\n Guerard says OPT-302 has received fast track designation from the US FDA for the treatment of wet AMD.<\/p>\n While OPT is focusing firstly on the US it says it will also be looking at other markets for approval including Europe and countries like Australia.<\/p>\n \u201cThe US is indeed a very large market and approvals are fairly fast and you can launch just after and so we are focusing indeed quite a lot on the US,\u201d Guerard says.<\/p>\n \u201cThe company is transitioning from being a small clinical stage organisation to a company that is preparing for a launch.\u201d<\/p>\n The OPT share price is up 12.50% YTD.<\/p>\n \ufeff<\/span><\/span><\/span>\u00a0 The post End in sight as Opthea looks to be key player in US$10 billion wet AMD market<\/a> appeared first on Stockhead<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"Potential to provide superior clinical results<\/h2>\n
