Adverum Biotechnologies Announces Positive Preliminary Efficacy and Safety Data from LUNA Phase 2 Trial of Ixo-vec in Patients with Wet AMD
– Both dose levels (2E11 & 6E10) demonstrate potential best-in-class clinical activity in hard-to-treat patients including treatment burden reduction and maintenance of both visual acuity and anatomic endpoints –
– Preliminary safety data support a favorable benefit-risk profile at both dose levels –

REDWOOD CITY, Calif., Feb. 08, 2024 (GLOBE NEWSWIRE) -- Adverum Biotechnologies, Inc. (Nasdaq: ADVM), a clinical-stage company pioneering the use of gene therapy as a new standard of care for highly prevalent ocular diseases, today announced preliminary safety and efficacy data from the ongoing LUNA Phase 2 trial in patients with wet age-related macular degeneration (AMD). These data are being presented by Dr. Arshad Khanani today at the 47th Annual Meeting of the Macula Society. The presentation titled “Ixoberogene soroparvovec (Ixo-vec) Intravitreal Gene Therapy for Neovascular Age-Related Macular Degeneration: Preliminary Results from the LUNA Phase 2 Study" is scheduled for 10:56am ET.
“Wet AMD is a leading cause of blindness in people over the age of 65, requiring life-long anti-VEGF injections. Our goal with Ixo-vec is to provide patients virtually injection-free management of their wet AMD lasting years and potentially for life,” stated Laurent Fischer, M.D., president and chief executive officer of Adverum Biotechnologies. “We are pleased with the emerging treatment profile of Ixo-vec, showing potential for best-in-class efficacy and over 90% of subjects having no or minimal inflammation with our go-forward local prophylactic regimen. Underscoring the potential best-in-class profile of Ixo-vec, these early activity results were seen in hard-to-treat patients, who received over 9 annualized injections in the year prior to receiving Ixo-vec. Going into LUNA, we looked to replicate the robust clinical activity seen in OPTIC, in which patients continued to see clinical benefit through 3 years, with measured stable aflibercept through 4.5 years. We are proud to build upon our pioneering efforts with the most mature dataset and longest follow-up of all wet AMD intravitreal gene therapies currently in development.”
Dr. Fischer continued, “Going into LUNA, we also looked to establish that an enhanced prophylactic regimen combined with highly active doses of Ixo-vec would further enhance its long-term benefit-risk profile. With these early data, we are pleased with the promising profile of Ozurdex plus difluprednate which we expect to be our go-forward regimen. We look forward to sharing the maturing LUNA dataset with the goal of confirming the optimal dose(s) and prophylactic regimen for pivotal studies and with the plan to present our 26-week interim analysis in the middle of 2024.”
“Based on my experience as an investigator for over five years across multiple clinical trials with Ixo-vec for wet AMD, it’s promising to see the sustained disease control and a significant treatment burden reduction after a single intravitreal injection of Ixo-vec in previously treated patients with wet AMD,” said Arshad M Khanani, M.D., M.A., FASRS, Managing Partner and Director of Clinical Research at Sierra Eye Associates, Clinical Associate Professor at University of Nevada, Reno and Principal Investigator in LUNA trial. “Ixo-vec has the potential to shift the treatment paradigm for patients with wet AMD and I look forward to working with the Adverum team to advance Ixo-vec into pivotal studies.”
LUNA Trial Background and Baseline Demographics
The LUNA trial is an ongoing double-masked, randomized, Phase 2 trial. 60 patients with wet AMD were enrolled equally across two dose cohorts, 2E11 and 6E10 vg/eye. The study is designed to assess optimized prophylactic regimens, with patients receiving one and/or two locally administered corticosteroid regimens, with or without oral prednisone.
The LUNA trial builds on our experience with the OPTIC study, where landmark 2-year data was recently published in The Lancet’s eclinicalmedicine.
The data cut-off for these data is November 15, 2023, except for treatment burden reduction, which is of January 2, 2024.
LUNA Preliminary Efficacy and Safety Data Summary
Both the 2E11 and 6E10 doses demonstrated maintenance of visual and anatomic outcomes. Notably, both doses resulted in a potentally best-in-class reduction in annualized anti-vascular endothelial growth factor (VEGF) injections and the percentage of patients remaining free of annualized injections, with data trending similar to or better than the OPTIC study.

About Wet Age-Related Macular Degeneration
Wet AMD, also known as neovascular AMD or nAMD, is a VEGF driven advanced form of AMD affecting approximately 10% of patients living with AMD associated with the build-up of fluid in the macula and the retina. Wet AMD is a leading cause of blindness in people over 65 years of age, with approximately 20 million individuals worldwide living with this condition. New cases of wet AMD are expected to grow significantly worldwide as populations age. AMD is expected to impact 288 million people worldwide by 2040, with wet AMD accounting for approximately 10% of those cases. Additionally, wet AMD is a bilateral disease, and incidence of nAMD in the second eye is up to 42% in the first two to three years. The current standard of care requires frequent life-long repeated bolus injections of anti-VEGF in the eye. IVT gene therapy has the promise to preserve vision and reduce most or all injections for the life of the patient by delivering stable therapeutic levels of anti-VEGF to control macular fluid.
About Ixo-vec in Wet AMD
Adverum is developing ixoberogene soroparvovec (Ixo-vec, formerly referred to as ADVM-022), its clinical-stage gene therapy product candidate, for the treatment of wet AMD. Ixo-vec utilizes a proprietary vector capsid, AAV.7m8, carrying an aflibercept coding sequence under the control of a proprietary expression cassette. Unlike other ophthalmic gene therapies that require surgery to administer the gene therapy under the retina (sub-retinal approach), Ixo-vec is designed to be administered as a one-time IVT injection in the physician’s office, deliver long-term efficacy, reduce the burden of frequent anti-VEGF, optimize patient compliance and improve vision outcomes for patients with wet AMD. In recognition of the need for new treatment options for wet AMD, FDA granted Fast Track designation for Ixo-vec for the treatment of wet AMD. Ixo-vec has also received PRIME designation from the EMA and the Innovation Passport from the United Kingdom’s Medicines and Healthcare Products Regulatory Agency for the treatment of wet AMD.
