Adverum Biotechnologies Reports Fourth Quarter and Full Year 2024 Financial Results and Provides Pipeline Highlights and Updates to Anticipated Milestones
REDWOOD CITY, Calif., April 15, 2025 (GLOBE NEWSWIRE) -- Adverum Biotechnologies, Inc. (Nasdaq: ADVM), a clinical-stage company pioneering the use of gene therapy to preserve sight for life in highly prevalent ocular diseases, today reported financial results for the fourth quarter and full year 2024. The company also provided pipeline highlights and updates to anticipated milestones.
“We believe Ixo-vec is poised to redefine the standard of care for patients with wet AMD as a potential best-in-class, one-and-done gene therapy. Ixo-vec offers the potential for life-long vision preservation and a favorable safety profile and is overwhelmingly preferred by patients over today’s treatment, as evidenced by our LUNA 52-week and OPTIC 4-year data,” stated Laurent Fischer, M.D., president and chief executive officer of Adverum Biotechnologies. “2025 is off to a strong start with the initiation of our first pivotal trial, ARTEMIS. Designed to enhance the potential for clinical, regulatory and commercial success, ARTEMIS will evaluate a broad patient population, including treatment naïve patients and patients with a high treatment burden, to provide confidence to retina specialists to prescribe Ixo-vec, if approved, across the spectrum of wet AMD patients. We look forward to sharing the design of our second pivotal trial, AQUARIUS, and to presenting long-term follow-up data from LUNA later this year.”
Ixo-vec Program Highlights
Initiated ARTEMIS, the first-ever registrational intravitreal gene therapy trial in patients with wet AMD
ARTEMIS is designed to derisk the clinical, regulatory and commercial path to approval. The inclusion of both treatment-experienced and treatment-naïve patients is expected to increase the speed of enrollment and generate a broad registrational dataset representative of real-world patient demographics to inform prescribers.
ARTEMIS is a US-based study evaluating a single administration of Ixo-vec (6E10 vg/eye) compared to on-label aflibercept (2mg) every 8 weeks in approximately 284 patients with wet AMD.
The primary endpoint is mean change from baseline of best corrected visual acuity (BCVA) at one year (average of weeks 52 and 56) with a non-inferiority margin of -4.5 letters.
Per FDA guidance, all patients will receive three loading doses of aflibercept prior to receiving Ixo-vec. Patients in both arms will be eligible for supplemental injections of aflibercept and will receive prophylactic steroid eye drops.
ARTEMIS is the first of two planned Phase 3 registrational trials to evaluate Ixo-vec in patients with wet AMD. Details on the second similar global study, AQUARIUS, are forthcoming.
Presented Phase 2 LUNA 52-week trial results
LUNA data support selection of 6E10 dose with topical eyedrops for pivotal program, providing evidence of potential best-in-class efficacy with favorable long-term safety.
6E10 dose in LUNA maintained visual and anatomic endpoints and continued to demonstrate potential best-in-class injection-free rates and reduction in injection burden.
Aflibercept levels were in the therapeutic range similar to those observed in OPTIC.
Ixo-vec was well tolerated, with local steroids effectively managing inflammation at both the higher 2E11 dose and the “go-forward” 6E10 dose.
Results from the LUNA pre-specified Patient Preference Survey demonstrate overwhelming preference for Ixo-vec over prior anti-VEGF therapies and for the acceptability of the topical steroid prophylaxis.
Presented OPTIC 4-year trial results
Despite significant treatment need at baseline, patients in OPTIC continued to experience long-term benefit from Ixo-vec through at least 4 years of follow up, including maintenance of vision, durability of anatomical improvements and sustained reduction in anti-VEGF treatment burden.
Stable aflibercept levels have been demonstrated as long as measured, up to 5 years post treatment.
Ixo-vec at 2E11 was generally well tolerated and demonstrated a favorable safety profile.
Long-term data establish a 10-fold safety margin from highest dose tested in wet AMD to the 6E10 dose selected for Phase 3.
Other Ixo-vec updates
“Nonclinical Study of Ixo-vec Gene Therapy for nAMD Supports Efficacy for a Human Dose of 6E10 vg/eye and Staggered Dosing of Fellow Eyes” published in Molecular Therapy – Methods and Clinical Development. This study supports staggered contralateral dosing of Ixo-vec, and dosing Ixo-vec at the 6E10 dose explored in LUNA, in patients with wet AMD.
Upcoming Anticipated Milestones
2H 2025 Initiate the global AQUARIUS Phase 3 trial
4Q 2025 Present Phase 2 LUNA two-year long-term follow-up data
Financial Results for the Three Months Ended December 31, 2024
Cash, cash equivalents and short-term investments were $125.7 million as of December 31, 2024, compared to $153.2 million as of September 30, 2024, and $96.5 million as of December 31, 2023. Adverum expects its cash, cash equivalents and short-term investments to fund operations into the second half of 2025.
Research and development expenses were $24.1 million for the three months ended December 31, 2024, compared to $15.3 million for the same period in 2023. Research and development expenses increased due to higher material production and bioanalytics expenses and higher compensation expenses in preparation for Phase 3 clinical trials. Stock-based compensation expense included in research and development expenses was $1.2 million for the fourth quarter of 2024.
General and administrative expenses were $18.5 million for the three months ended December 31, 2024, compared to $11.7 million for the same period in 2023. General and administrative expenses increased due to increases in a non-cash tenant improvement allowance made available to a subtenant for our North Carolina premises and higher consultant fees. Stock-based compensation expense included in general and administrative expenses was $2.0 million for the fourth quarter of 2024.
Net loss was $40.9 million, or $1.96 per basic and diluted share, for the three months ended December 31, 2024, compared to $24.5 million, or $2.42 per basic and diluted share for the same period in 2023.
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 and Regenerative Medicine Advanced Therapy (RMAT) designations 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.
