Graybug Vision Reports Full Year 2021 Financial Results and Recent Corporate Developments

Mar 10, 2022 7:30 AM EST

Management to host R&D Day for investors on March 30, 2022 at 11 a.m. ET

BALTIMORE, March 10, 2022 (GLOBE NEWSWIRE) -- Graybug Vision, Inc. (Nasdaq: GRAY), a clinical-stage biopharmaceutical company focused on developing transformative medicines for the treatment of ocular diseases, today provided an update on recent corporate developments and reported financial results for the full year ended December 31, 2021.

“Graybug made important progress in advancing its retina (GB-102) and glaucoma (GB-401) programs in 2021. We developed a new enhanced formulation of GB-102 that capitalizes on the duration demonstrated by our Phase 2b ALTISSIMO trial, where half of patients were controlled for six months after a single intravitreal (IVT) injection,” said Frederic Guerard, PharmD, Chief Executive Officer of Graybug Vision. “We are in ongoing discussions to partner GB-102 for its next clinical trial, while finalizing the preparation of an IND application for our GB-401 implant formulation, and pursuing other novel ocular therapeutics.”

Recent Corporate Developments

  • Completed ALTISSIMO Phase 2b trial in wet age-related macular degeneration (wet AMD) — Final results confirm unprecedented duration in an aflibercept-controlled clinical trial. GB-102 1mg demonstrated six-month duration in 48% of patients and 12 months in 30% of patients, with well-controlled central subretinal thickness (CST), as compared to aflibercept. Best corrected visual acuity (BCVA) of patients in the GB-102 1mg arm trended lower than aflibercept’s, mainly driven by 4 subjects. These subjects had a combination of high anti-VEGF need prior to enrollment, particle dispersion during the study, or adverse events unrelated to the drug, which we expect to address in the next trial with optimized inclusion and rescue criteria, and our new enhanced formulation.
  • Ongoing partnering discussions to support funding of additional GB-102 wet-AMD clinical trials — New enhanced formulation of GB-102 to further reduce or eliminate microparticle dispersion has been developed, and design of future Phase 2 trial to evaluate safety, efficacy, and durability has been finalized.
  • Developed lead GB-401 formulation and custom pre-loaded applicator — Expanded biodegradable polymer platform technology with implant formulation of GB-401, which has the potential to be administered IVT once every six months with a pre-loaded applicator to reduce elevated intraocular pressure in glaucoma patients, is currently in a repeat-dose GLP-tox study.
  • Pursuing expansion of pipeline with focus on early-stage novel therapeutics addressing unmet ophthalmic needs — In-licensing efforts targeted at capital-efficient development opportunities are expected to both leverage and expand current platform technologies.

Anticipated Milestones

  • Enhanced GB-102 formulation ready for Phase 2 trial in patients with wet AMD as soon as second half of 2022.
  • Initiate GB-401, a proprietary implant formulation of a beta-adrenergic receptor inhibitor designed for IVT injection once every six months, Phase 1 trial in first half 2023.

Full Year 2021 Financial Results

Net loss for 2021 was $35.8 million compared to $27.5 million for 2020. Net loss for 2020 included a non-cash gain of $2.2 million resulting from the modification and expiration of the liability related to the preferred stock tranche obligation that was permanently eliminated in connection with the company’s initial public offering, or IPO, in September 2020. Excluding this gain, the 2020 net loss would have been $29.7 million.

Research and development expense for 2021 was $18.9 million compared to $21.0 million for 2020. The decrease in 2021 was primarily due to a reduction in clinical trial expenses due to the completion of the treatment phase of the GB-102 Phase 2b ALTISSIMO clinical trial in December 2020, offset in part by an increase in compensation costs.

General and administrative expense for 2021 was $17.0 million compared to $8.9 million for 2020. The increase in 2021 was primarily due to a $2.8 million increase in stock-based compensation, a $1.8 million increase in the cost of directors and officers insurance as a result of becoming a public company and a $1.3 million write-off of deposits on fixed assets purchase commitments.

As of December 31, 2021, the company’s cash, cash equivalents, and short-term investments totaled $63.7 million, compared to $95.0 million as of December 31, 2020. The decrease was primarily due to our net loss in 2021 of $35.8 million. The company’s current cash and investments are sufficient to support its planned operations into the second half of 2023.

R&D Day for Investors

Management plans to host an Investor R&D Day on March 30, 2022 from 11 a.m. to 12:45 p.m. ET.
