Graybug Vision Announces First Quarter 2021 Financial Results and Recent Corporate Developments

REDWOOD CITY, Calif., May 12, 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 quarter ended March 31, 2021.

Recent Corporate Developments

• Full-data analysis from 12-month treatment phase of ALTISSIMO Phase 2b trial in wet AMD— GB-102 1mg has shown competitive durability and anatomical control versus aflibercept; trend in mean BCVA of GB-102 1mg compared to aflibercept driven primarily by a subgroup of patients.
• Six-month observational trial extension of ALTISSIMO still underway— 14 of 28 patients enrolled have completed at least five months of the extension period without requiring additional supportive therapy, with six of those having completed all six months. 
• Seeking partner for funding of additional wet AMD clinical trials— Enhanced formulations of GB-102 being developed and preclinical work progressing in parallel.
• Clinical focus shifting to advancement of GB-401 implant for glaucoma— Disclosed development of implant technology for GB-401 with potential application to GB-102.

Anticipated Milestones

• Complete six-month observational trial extension of ALTISSIMO by June 2021, with topline data expected in 3Q 2021.
• Expected to present full results of ALTISSIMO trial at a medical conference in 4Q 2021.
• Submit Investigational New Drug (IND) application for GB-401, an injectable formulation of a beta-adrenergic blocker prodrug, for primary open-angle glaucoma, with a dosing regimen of once every six months or longer, in the first half of 2022.
• Commence a Phase 1 trial for GB-401 implant in glaucoma in the first half of 2022.

First Quarter 2021 Financial Results

Net loss for the quarter ended March 31, 2021 was $11.4 million compared to $7.8 million for the same period in 2020.

Research and development expense for the quarter ended March 31, 2021 was $6.4 million compared to $6.1 million for the same period in 2020. The increase was primarily due to fees incurred upon the cancellation of clinical supply orders for the GB-102 Phase 3 trial and increased compensation costs, offset in part by a reduction in clinical trial expenses due to the completion of the treatment phase of the ALTISSIMO trial in December 2020.

General and administrative expense for the quarter ended March 31, 2021 was $5.0 million compared to $1.7 million for the same period in 2020. The increase in 2021 was primarily due to the write-off of deposits on fixed assets purchase commitments, an increase in stock-based compensation and an increase in headcount, and the increased cost of additional directors and officers insurance as a result of becoming a public company.

As of March 31, 2021, the company’s cash, cash equivalents, and short-term investments totaled $85.7 million, compared to $95.0 million as of December 31, 2020. The decrease was primarily due to the loss from operations of $11.5 million. The company’s current cash and investments are sufficient to support its currently planned operations into the first half of 2023.
