SBT-589 showed mitochondrial protection across models of Friedreich's ataxia SBT-589 displayed cardioprotective effects in aggressive mouse model of FA cardiomyopathy Ongoing studies are expected to build on these insights as SBT-589 progresses through developmental stage-gates NEEDHAM, Mass., March 19, 2024 /PRNewswire/ -- Stealth BioTherapeutics Inc. (the "Company" or "Stealth"), a clinical-stage biotechnology company focused on the discovery, development, and commercialization of novel therapies for diseases involving mitochondrial dysfunction, announced today the presentation of new SBT-589 data demonstrating cardioprotective effects across pre-clinical models of Friedreich's ataxia (FA). The data were presented at the Wellcome Trust Conference on Mitochondrial Medicine – Therapeutic Development, held March 18-20, 2024, in Cambridge, England. FA is a chronic disease of metabolic disruption that is typically diagnosed in childhood or adolescence, is inexorably progressive and usually results in premature death from cardiomyopathy or heart failure. There are no approved therapies for the progressive cardiomyopathy, which is linked to severe mitochondrial dysfunction, and is the leading cause of early death in this devastating disease. SBT-589 is a promising novel molecule that acts on mitochondrial pathways essential for cellular health and energy production that are impaired in FA cardiomyopathy. To evaluate the potential of SBT-589 in FA, a series of studies were conducted in FA patient-derived cells, isolated heart mitochondria, and an aggressive mouse model of FA cardiomyopathy. SBT-589 improved bioenergetics in FA patient-derived cells and mitochondria. In an FA mouse model with prominent cardiac hypertrophy and aggressive mortality, mice treated with once-daily SBT-589 displayed significantly reduced cardiac hypertrophy and a delay in the onset of mortality compared to vehicle-treated mice. "Mitochondrial dysfunction is a central contributor to pathology in Friedreich's ataxia, a disease in which heart failure and sudden cardiac events are among the leading causes of mortality," said David A. Brown, Senior Vice President, Discovery. "Mitigating heart disease in FA is central to Stealth's ongoing efforts to improve the lives of individuals with FA. The new findings presented today support continued development of SBT-589 as a potentially disease-modifying therapy to address the unmet need in cardiomyopathy associated with Friedreich's ataxia." The data were presented by Dr. Laura E. Kropp, Senior Manager of Discovery Biology at Stealth, and recipient of the Keith Michael Andrus Cardiac Award from the Friedreich's Ataxia Research Alliance. About Friedreich's Ataxia Friedreich's ataxia is a rare genetic disease affecting an estimated 1 in 50,000 individuals in the United States. The disease is caused by a defect in the frataxin gene resulting in a relative deficiency of frataxin, leading to mitochondrial iron accumulation and oxidative stress. More than 90% of patients with Friedreich's ataxia experience progressive cardiomyopathy which usually becomes fatal by early adulthood and is the leading cause of early mortality. About Stealth BioTherapeutics Stealth BioTherapeutics is a clinical-stage biotechnology company focused on the discovery, development, and commercialization of novel therapies for age-related and rare genetic diseases involving mitochondrial dysfunction. The Company is initiating Phase 3 clinical trials of elamipretide, its lead investigational product candidate, in dry age-related macular degeneration.

ATLANTA, March 19, 2024 (GLOBE NEWSWIRE) -- Alimera Sciences, Inc. (Nasdaq: ALIM) (“Alimera”), a global pharmaceutical company whose mission is to be invaluable to patients, physicians and partners concerned with retinal health and maintaining better vision longer, announces that the first patient has been randomized in the DRCR Retina Network’s Protocol AL. The study is titled, “A Randomized Clinical Trial Evaluating Intravitreal Faricimab (6.0 mg) Injections or Fluocinolone Acetonide (0.19 mg) Intravitreal Implants vs Observation for Prevention of Visual Acuity Loss due to Radiation Retinopathy.” The study, chaired by Arun Singh, M.D. (Cole Eye Institute, Cleveland Clinic, Cleveland, Ohio), plans to include 600 participants with primary choroidal melanoma receiving treatment with plaque brachytherapy. It will assess development of macular edema and associated long-term visual acuity effects of consistent and continuous release of corticosteroid or repeated injections of anti-VEGF initiated near the time of radiation therapy compared to observation until macular edema develops in patients at risk for radiation retinopathy. “We are very excited that this study is underway as it has the potential to show ILUVIEN addressing another unmet need affecting the retina,” said Rick Eiswirth, President and Chief Executive Officer of Alimera. “We believe ILUVIEN with CONTINUOUS MICRODOSING™ delivery may prevent, delay or reduce the occurrence of the complication of radiation retinopathy and consequent vision loss when used in patients treated with plaque brachytherapy and look forward to the continuing progress of this study.” About Radiation Retinopathy Radiation retinopathy (RR) is a common complication after Iodine-125 plaque brachytherapy for choroidal melanoma. Although the initial radiation insult is immediate, clinical onset of RR is not seen until many months later and RR frequently progresses over time to profound vision loss. The Collaborative Ocular Melanoma Study reported that at three years, 45% of patients have visual acuity 20/200 or worse. A treatment that prevents the development of RR, or dampens its severity, would have important consequences for many of these eyes that may be successfully treated for choroidal melanoma but will likely develop severe RR and loss of vision over time. About the DRCR Retina Network (DRCR.net) The DRCR Retina Network was formed in 2002 and includes clinical sites and physicians throughout the United States and Canada. It is funded by the National Eye Institute (NEI), part of the National Institutes of Health, which is the federal government agency that funds medical research. The DRCR Retina Network is supported in overall operation and leadership by the office of the Network Chairs (Daniel F. Martin, M.D., Cole Eye Institute, Cleveland Clinic, Cleveland, Ohio and Jennifer K. Sun, M.D., M.P.H., Joslin Diabetes Center, Harvard Medical School, Boston, Massachusetts) and the Coordinating Center (Executive Director Adam R. Glassman, M.S., Jaeb Center for Health Research, Tampa, FL), and the National Eye Institute (Project Officer, Sangeeta Bhargava, Ph.D.). About ILUVIEN The Company’s primary product is ILUVIEN (fluocinolone acetonide intravitreal implant) 0.19 mg sustained release intravitreal implant, injected into the back of the eye. With its CONTINUOUS MICRODOSING™ technology, ILUVIEN is designed to release sub-microgram levels of fluocinolone acetonide, a corticosteroid, for 36 months, to reduce the recurrence of disease, enabling patients to maintain vision longer with fewer injections. ILUVIEN is approved in the U.S., Kuwait, Lebanon and the U.A.E. to treat diabetic macular edema (DME) in patients who have been previously treated with a course of corticosteroids and did not have a clinically significant rise in intraocular pressure. In 17 European countries, ILUVIEN is indicated for the treatment of vision impairment associated with chronic DME considered insufficiently responsive to available therapies. In March 2019, ILUVIEN received approval in the 17 countries under the Mutual Recognition Procedure for prevention of relapse in recurrent non-infectious uveitis affecting the posterior segment of the eye. The 17 European countries include the U.K., Germany, France, Italy, Spain, Portugal, Ireland, Austria, Belgium, Denmark, Norway, Finland, Sweden, Poland, Czechia, the Netherlands, and Luxembourg. The non-infectious posterior uveitis indication for ILUVIEN was launched in Germany and the U.K. in late 2019, Belgium in 2021 and Spain and Italy in 2022. Alimera markets YUTIQ® (fluocinolone acetonide intravitreal implant) 0.18mg for treatment of uveitis in the United States. About Alimera Sciences, Inc.

ROCKVILLIE, Md. and SUZHOU, China, March 18, 2024 /PRNewswire/ -- Innovent Biologics, Inc. ("Innovent") (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high quality medicines for the treatment of cancer, metabolic, autoimmune and other major diseases, today announced that the primary endpoint has been met in the second Phase 2 clinical study of efdamrofusp alfa high-dose, a recombinant human VEGFR-Fc-Human CR1 fusion protein injection (R&D code: IBI302), in Chinese subjects with neovascular age-related macular degeneration (nAMD). According to the results of the two Phase 2 clinical studies conducted in more than 360 subjects of nAMD, compared with Aflibercept, IBI302 can be administrated in long-interval (every 12 weeks), while providing a stable and robust visual benefit and anatomic improvements, as well as potential inhibition effect in macular atrophy. Based on those results, Innovent advanced IBI302 8mg into a Phase 3 clinical study STAR in October 2023. This was a randomized, double-masked, active-controlled Phase 2 clinical study (NCT05403749), evaluating the longer interval of intravitreal injection of high-dose IBI302 in subjects with nAMD. A total of 132 subjects were randomized 1: 1: 1 to IBI302 6.4 mg group, IBI302 8.0 mg group, or Aflibercept 2.0 mg group. After the loading therapy, subjects in IBI302 6.4 mg group and 8.0 mg group were dosed with adjusted intervals of every 8 weeks (Q8W) or every 12 weeks (Q12W), depending on response to loading therapy. Subjects in Aflibercept 2.0 mg group were dosed Q8W after the loading therapy. The primary endpoint was the change in best corrected visual acuity (BCVA) in the study eye from baseline to week 40. The study lasted for 52 weeks. The results showed that the primary endpoint was successfully met: at week 40, the IBI302 6.4 mg and 8.0 mg groups showed non-inferior BCVA gains to the Aflibercept 2.0 mg group. The mean BCVA improvement from baseline was 10.5 ETDRS letters for the IBI302 6.4 mg group, 11.0 ETDRS letters for the IBI302 8.0 mg group, and 9.8 ETDRS letters for the Aflibercept 2.0 mg group at week 40. The mean change from baseline in central subfield thickness (CST) was -163.19 μm for the IBI302 6.4 mg group, -184.46 μm for the IBI302 8.0 mg group, and -108.23 μm for the Aflibercept 2.0 mg group at week 40. In addition, approximately 81%, 88% of subjects in 6.4 mg IBI302 groups and 8.0mg IBI302 groups respectively were able to extend dosing interval to Q12W, similar to that in the proportion of subjects dosed Q12W or longer with Aflibercept 8.0 mg (83% in PULSAR trial)1 or Faricimab (TENAYA & LUCERNE trial, with 79.7% and 77.8% respectively)2 by indirect comparison. Based on the excellent long-interval dosing performance in the Phase 2 studies, the Phase 3 study STAR added Q16W dosing interval regimen for IBI302. The overall safety profile of IBI302 was favorable, comparable to Aflibercept 2.0 mg, and consistent with previous studies. No new safety signals were identified. Detailed study data will be further analyzed and published in the near future. Professor Xiaodong Sun, Principal Investigator of the Study, Head of National Center for Clinical Ophthalmology, Shanghai General Hospital, stated: "Intravitreal injection of anti-VEGF drugs is currently the first-line treatment for nAMD, but there are still unmet clinical needs given their frequent intravitreal injection and gradual loss of visual benefits. Exploring longer interval dosing and anti-macular atrophy are necessary and urgent. IBI302 is a global first-in-class anti-VEGF-anti-complement bispecific molecule. As the principal investigator for IBI302 trials, I am very pleased to see that this Phase 2 study met the primary endpoint and demonstrated the potential for long-interval dosing. These results will be further validated in the pivotal trial of IBI302. I look forward to providing a new treatment option for nAMD patients." Dr. Lei Qian, Vice President of Clinical Development of Innovent, stated: "There are two major trends in drug development for nAMD: extending dosing intervals and reducing the occurrence of macular atrophy. In the results of two Phase 2 studies, which enrolled over 360 subjects, IBI302 improved BCVA and macular edema in patients with nAMD significantly, extended dosing intervals, and had the potential to prevent the development of macular atrophy. Next, we will further investigate the long-interval dosing efficacy and safety of high-dose IBI302 in the Phase 3 STAR trial, hoping to bring a new generation of anti-VEGF agents to patients with nAMD." About neovascular age-related macular degeneration (nAMD) Age-related macular degeneration (AMD) is a progressive ocular disease involving the macular retina, leading to central visual impairment, the incidence of which increases with age. Neovascular age-related macular degeneration (nAMD) is one of the major forms of AMD, accounting for 15% to 20% of all AMD patients and is the leading cause of central vision loss in AMD patients over 65 years3. The incidence of AMD is increasing year by year in China, and it has become the third leading cause of blindness in China. The pathogenesis of nAMD has not been fully elucidated. It is generally accepted that angiogenesis induced by increased expression of VEGF is the main cause of nAMD, and inflammatory reaction mediated by abnormal activation of complement is also considered to be an important cause of AMD. Ocular anti-VEGF agents have led to significant visual benefits and changed the course of nAMD, but the frequent dosing (every 4 or 8 weeks) currently places a heavy burden on patients, families and society. In addition, the visual benefits of anti-VEGF drug therapy are gradually diminished year by year. In approximately two thirds of nAMD patients with a follow-up for over 7 years, the visual gains from anti-VEGF treatment significantly diminish4. Macular atrophy or retinal fibrosis are important causes of vision loss after long-term anti-VEGF therapy. Currently, drug development for nAMD is mainly focusing on extending the dosing intervals, and there are few drugs under investigation for macular atrophy or retinal fibrosis. Two drugs targeting complement have been approved by the US FDA in 20235,6 for the treatment of geographic atrophy secondary to dry AMD. About Efdamrofusp Alfa (IBI302) IBI302 is a recombinant fully human bispecific fusion protein of Innovent Biologics with global proprietary rights. The N-terminus is a VEGF domain that can bind to the VEGF family, block VEGF-mediated signaling pathway, inhibit vascular epithelium proliferation and angiogenesis, and improve vasopermeability and reduce leakage. The C-terminus of IBI302 is the complement binding domain that can inhibit the activation of the classic pathway and alternative pathway of complement through the specific binding of C3b and C4b, and reduce the inflammatory response mediated by the complement. IBI302 may exert its therapeutic effect by inhibiting both VEGF-mediated angiogenesis and complement activation pathways.
