REDWOOD CITY, Calif., March 04, 2021 (GLOBE NEWSWIRE) -- Graybug Vision, Inc. (Nasdaq: GRAY), a clinical-stage biopharmaceutical company focused on developing transformative medicines for the treatment of diseases of the retina and optic nerve, today provided an update on recent corporate developments and reported financial results for the full year ended December 31, 2020.
“We are very pleased with Graybug’s achievements in 2020. Amidst a challenging pandemic, we completed our initial public offering and advanced our lead product candidate GB-102 in retinal disease through the treatment phase of its Phase 2b ALTISSIMO trial in wet age-related macular degeneration (wet AMD). I am excited to share that we are now on track to report topline data from our ALTISSIMO trial by the end of this month,” said Frederic Guerard, PharmD, Chief Executive Officer of Graybug.
Recent Corporate Developments
Completion of 12-month treatment phase of ALTISSIMO trial in wet AMD — 50 patients out of the 56 initially enrolled completed the 12-month treatment phase of the three-arm, randomized, and masked trial of GB-102 in December 2020. Six patients did not complete the study for reasons unrelated to their treatments. Topline data for this 12-month treatment phase are expected to be announced in March 2021.
Initiation of 6-month observational trial extension of ALTISSIMO — 28 of the 50 patients who completed their Month 12 visit were eligible and agreed to continue masked clinical monitoring until the point at which they require additional supportive therapy, up to a maximum of six months. As of today, 22 patients have successfully completed two months or more of this six-month extension period without the need for further treatment.
Named Bettina Maunz as Chief People Officer — Ms. Maunz is building and leading the human resources function as a member of Graybug’s executive team and serves as Head of Communications.
Anticipated Milestones in 2021
Communicate topline data for the 12-month treatment phase of ALTISSIMO in March 2021, with full results to be presented at a medical conference expected in 3Q 2021.
Complete 6-month observational trial extension of ALTISSIMO by June 2021, with topline data expected in 3Q 2021.
Initiate two pivotal Phase 3 trials for GB-102 in patients with wet AMD in the second half of 2021.

Full Year 2020 Financial Results
Net loss for 2020 was $27.5 million compared to $37.0 million for 2019. 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 2020 was $21.0 million compared to $30.6 million for 2019. The decrease in 2020 was primarily due to the fact that the company did not engage in any primary manufacturing activities in 2020 compared with 2019, during which the company manufactured the clinical supplies for the ALTISSIMO clinical trial that commenced later in the third quarter of 2019.
General and administrative expense for 2020 was $8.9 million compared to $6.9 million for 2019. The increase in 2020 was primarily due to additional professional services, related in part to preparing for and becoming a public company, and the related increased cost of additional D&O insurance.
As of December 31, 2020, the company’s cash, cash equivalents, and short-term investments totaled $95.0 million, compared to $36.0 million as of December 31, 2019. The increase was due to the receipt of $92.1 million in net proceeds from the company’s IPO. The company’s current cash and investments are sufficient to support its planned operations into the first quarter of 2022.
Graybug is a clinical-stage biopharmaceutical company focused on developing transformative medicines for the treatment of diseases of the retina and optic nerve. The company’s proprietary ocular delivery technologies are designed to maintain effective drug levels in ocular tissue for six months and potentially longer, improving disease management, reducing healthcare burdens and ultimately delivering better clinical outcomes. Graybug’s lead product candidate, GB-102, a microparticle depot formulation of the pan-vascular endothelial growth factor (VEGF) inhibitor, sunitinib malate targeting a six-month or longer dosing regimen, inhibits multiple neovascular pathways for the intravitreal treatment of retinal diseases, including wet age-related macular degeneration. Graybug is also using its proprietary technologies to develop GB-401, an injectable depot formulation of a beta-adrenergic blocker prodrug, for primary open-angle glaucoma, with a dosing regimen of once every six months or longer, and GB-103, a longer-acting version of GB-102, designed to maintain therapeutic drug levels in the retinal tissue for 12 months with a single injection. Founded in 2011 on the basis of technology licensed from the Johns Hopkins University School of Medicine, Graybug is headquartered in Redwood City, California.
