REDWOOD CITY, Calif., Aug. 10, 2020 (GLOBE NEWSWIRE) -- Adverum Biotechnologies, Inc. (Nasdaq: ADVM), a clinical-stage gene therapy company targeting unmet medical needs in ocular and rare diseases, today announced positive new interim data from Cohorts 1-4 of the OPTIC Phase 1 clinical trial of ADVM-022 intravitreal (IVT) injection gene therapy in patients requiring frequent anti-VEGF injections for their wet age-related macular degeneration (AMD). The company also reported recent business progress and financial results for the second quarter ended June 30, 2020.
For the first time, interim data from all four cohorts of the OPTIC trial (July 23, 2020 cutoff date), including preliminary safety data from Cohort 4, are presented. These data further demonstrate the transformative potential of ADVM-022 to greatly reduce the treatment burden for patients with wet AMD:
ADVM-022 continues to show robust treatment response
Mean BCVA1 maintained
Mean CRT2 maintained to improved
Long-term durability beyond 15 months from single IVT injection with zero anti-VEGF rescue injections in Cohort 1 (high dose)
Further evidence of a dose response:
High dose: 6/63 patients rescue injection free
Low dose: 10/154 patients rescue injection free
Substantial reduction in annualized anti-VEGF injection rate following administration of ADVM-0225:
High dose: 100%
Low dose: 87%
ADVM-022 continues to be well tolerated with a favorable safety profile in all 4 cohorts (n=30)
All ADVM-022-related ocular adverse events (AE) were mild (78%) to moderate (22%)
One AE of special interest of moderate recurrent uveitis deemed to be related to ADVM-022 was responsive to steroid eye drops (Cohort 1)
Ocular inflammation, when observed, has been responsive to steroid eye drops
No clinical or fluorescein6 evidence of posterior inflammation
No vasculitis, retinitis, choroiditis, vascular occlusions, or endophthalmitis
Early evidence from Cohort 4, consistent with Cohort 3, suggests that a prophylactic regimen of steroid eye drops results in fewer adverse events and less inflammation, when compared to a prophylactic regimen of oral steroids as used in Cohorts 1 and 2. In Cohorts 3 and 4, no patients have required more than steroid eye drops.

Arshad M. Khanani, M.D., M.A., managing partner and director of clinical research, Sierra Eye Associates, clinical associate professor of ophthalmology, University of Nevada, and top enrolling investigator in the OPTIC trial said, “In my experience the sustained anatomical treatment response following a single intravitreal injection of ADVM-022 is unprecedented, which is remarkable considering that the patients enrolled in OPTIC were difficult-to-treat and had previously required frequent injections to maintain their vision. The safety profile to date shows that ADVM-022 is well tolerated, and that the prophylactic steroid eye drop regimen has been effective at limiting early ocular inflammation. I believe that ADVM-022 has the potential to be a transformational gene therapy improving real-world outcomes for patients living with wet AMD.”
Aaron Osborne, MBBS, chief medical officer of Adverum, added, “We have completed dosing patients in OPTIC, with 30 patients being followed up across four cohorts, and we look forward to presenting additional data from these cohorts by the end of this year. With the exciting data presented to date from OPTIC highlighting the potential of ADVM-022 to dramatically reduce treatment burden for patients with wet AMD, we plan to seek U.S. and international regulatory authorities’ input as we progress towards initiating a pivotal clinical trial in mid-2021.”
Laurent Fischer, M.D., chief executive officer of Adverum stated, “With these impressive OPTIC data, we are now poised to move our potentially transformative therapy into pivotal trials. ADVM-022, a novel gene therapy providing continuous delivery of aflibercept, has the potential to be a “one and done” IVT injection that would dramatically reduce the treatment burden for the millions of patients with wet AMD and DME worldwide. As we continue to see positive data from ongoing trials, we are preparing to accelerate our development and future commercial launch plans for ADVM-022. We continue to add industry-leading talent to our team and are beginning to expand our business operations and capabilities, including clinical, regulatory, manufacturing, and pre-commercial functions. It’s an exciting time at Adverum, and I’m humbled by the dedication of the retina specialists, their patients and our employees for their tireless efforts to help patients with severe ocular diseases during a pandemic.”
INFINITY Phase 2 Clinical Trial of ADVM-022 in Diabetic Macular Edema
Began randomizing patients in the INFINITY trial. INFINITY is a Phase 2, multi-center, randomized, double-masked, active comparator-controlled trial in approximately 33 patients with diabetic macular edema (DME). Diabetes impacts over 30 million people in the United States and over 400 million people globally and is increasing in prevalence. Approximately 5% of adults with diabetes are impacted by DME, a vision-threatening complication of diabetic retinopathy.
INFINITY is designed to demonstrate superior control of disease activity following a single IVT injection of ADVM-022 compared to a single aflibercept injection, as measured by time to worsening of DME disease activity in the study eye
Additional objectives include assessments of treatment burden, visual acuity, retinal anatomy and safety outcomes

To date, Adverum has experienced limited impact from COVID-19 on its operations and ongoing clinical programs, including the OPTIC and INFINITY clinical trials. The company is continuing to monitor and attempt to address or limit the potential impacts of COVID-19 on its employees and operations, patient safety, patient enrollment, continued participation of patients already enrolled in the company’s clinical studies, protocol compliance, data quality, and overall study integrity.
Financial Results for the Three Months Ended June 30, 2020
Cash, cash equivalents and short-term investments were $280.1 million as of June 30, 2020, compared to $166.0 million as of December 31, 2019. Adverum expects this quarter-end cash position to fund operations into 2022.
Research and development expenses were $19.2 million for the three months ended June 30, 2020, compared to $9.0 million for the same period in 2019. Research and development expenses increased primarily due to higher material production costs and personnel-associated costs. Stock-based compensation expense included in research and development expenses was $1.7 million for the second quarter of 2020.
General and administrative expenses were $10.6 million for the three months ended June 30, 2020, compared to $7.1 million for the same period in 2019. General and administrative expenses increased primarily due to higher personnel-associated costs as well as depreciation expense for Adverum’s new headquarters. Stock-based compensation expense included in general and administrative expenses was $3.1 million for the second quarter of 2020.
Net loss was $29.2 million, or $0.36 per basic and diluted share, for the three months ended June 30, 2020, compared to $15.0 million, or $0.23 per basic and diluted share, for the same period in 2019.

About the OPTIC Phase 1 Trial of ADVM-022 in Wet AMD
This multi-center, open-label, Phase 1, dose-ranging trial is designed to assess the safety and tolerability of a single intravitreal (IVT) administration of ADVM-022 in patients with wet AMD who are responsive to anti-vascular endothelial growth factor (VEGF) treatment. Patients received a high dose (6 x 10^11 vg/eye) of ADVM-022 in Cohort 1 (n=6) and Cohort 4 (n=9) and patients received a low dose (2 x 10^11 vg/eye) of ADVM-022 in Cohort 2 (n=6) and Cohort 3 (n=9). Patients in Cohorts 3 and 4 received six weeks of prophylactic steroid eye drops rather than 13 days of prophylactic oral steroids which were used in Cohorts 1 and 2. The primary endpoint of the trial is the safety and tolerability of ADVM-022 after a single IVT administration. Secondary endpoints include changes in best-corrected visual acuity (BCVA), measurement of central retinal thickness (CRT), as well as the need for anti-VEGF rescue injections. Each patient enrolled will be followed for a total of two years.
Eleven leading retinal centers across the United States are participating in the OPTIC Phase 1 trial for ADVM-022. For more information, please visit https://clinicaltrials.gov/ct2/show/NCT03748784.
