BOSTON, Nov. 09, 2022 (GLOBE NEWSWIRE) -- GreenLight Biosciences Holdings, PBC (Nasdaq:GRNA), a public benefit corporation striving to bring effective and safe solutions to make food clean and affordable for everyone and dedicated to developing health solutions for every person on our planet, today reported operational highlights and financial results for the third quarter ended September 30, 2022.

“We continue to make progress against our key goals, which include obtaining proof-of-concept for our mRNA platform in human health and progressing late-stage plant health programs toward commercialization. This quarter we carried out a strategic realignment to better optimize our R&D efforts and prioritize our nearer-term value drivers. These efficiencies, combined with our August financing, will help us navigate today’s challenging market conditions,” said Andrey Zarur, CEO of GreenLight. “In 2023, pending EPA approval, we anticipate bringing Calantha™, the first-ever foliar-applied RNA solution for crop protection, to market and submitting a regulatory application for our honeybee solution. In addition, we are pursuing potential opportunities to enable us to initiate clinical trials for our COVID-19 vaccine candidate and continuing to work with Serum Institute of India (SII) on identifying and developing a shingles vaccine candidate.”

Third Quarter 2022 and Recent Operational Highlights:

CORPORATE UPDATE:

In October 2022, GreenLight announced a strategic realignment to preserve resources and extend the Company’s cash runway by focusing operational expenses on advanced-stage programs and those with near-term value drivers. Reflective of this shift, GreenLight implemented a 25% reduction in workforce with cost optimizations expected to generate savings of approximately $13 million in direct employee costs in 2023 with expected additional savings from other direct and indirect cost areas.

HUMAN HEALTH PORTFOLIO:

GreenLight is applying its mRNA platform technology and scalable production capabilities to rapidly develop cost-effective vaccine and therapeutic candidates for diseases prevalent in underserved and emerging markets. Beyond independent efforts, GreenLight has numerous research collaborations in place to support this work, including with Serum Institute of India (SII), National Institutes of Health (NIH), the Bill and Melinda Gates Foundation, and others.

COVID-19: GreenLight is designing mRNA vaccines for COVID-19, leveraging its platform-manufacturing advantages to produce more broadly accessible vaccines.

• GreenLight has completed preclinical testing for GLB-CoV-2-043, its vaccine product candidate targeting the original “Wuhan” strain of the COVID-19 virus.
• Upon feedback from the South Africa Health Products Regulatory Authority (SAHPRA), GreenLight decided not to amend or resubmit its clinical trial application with SAHPRA in favor of identifying other countries in which to begin clinical trials and whether to do so in combination with an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA).
• Subject to our ability to identify a viable country and obtain applicable regulatory approvals, we are continuing to work toward initiating a Phase I/II clinical trial by the first half of 2023. This will evaluate our COVID-19 vaccine candidate, GLB-CoV-2-043 as a single-vaccination booster.
• GreenLight also continues to work with the Vaccine Research Center (VRC), part of the National Institute of Allergy and Infectious Diseases (NIAID) at NIH, to co-design and test COVID-19 vaccines with the goal of developing vaccines that are more broadly protective against new variants and confer longer-lasting effects than current vaccines.

Shingles: GreenLight is designing an mRNA vaccine for shingles as part of its partnership with SII, which also includes up to two potential additional vaccine or therapeutic targets.

• GreenLight is designing antigens and conducting preclinical research on a potential shingles vaccine candidate and currently anticipates nominating a development candidate for shingles in 2023.
• SII is responsible for subsequent clinical and manufacturing development, as well as regulatory and commercial activities in the licensed regions.

PLANT HEALTH PORTFOLIO:

GreenLight is advancing double-stranded RNA (dsRNA) solutions for agricultural applications, including crop protection, designed to control pests and address resistance and residues of chemical alternatives, impacting food security and climate change. The Company has seven agricultural solutions in active development, with an estimated total addressable market of $6 billion in 2026.

Calantha: a foliar-applied dsRNA pesticide to protect against the Colorado potato beetle, which causes hundreds of millions of dollars in damage every year and has developed resistance to many currently available chemical products.

• GreenLight submitted an application to register this product candidate with the U.S. Environmental Protection Agency (EPA) and subject to regulatory approval in the first half of 2023, GreenLight is planning to launch this product commercially in the following growing season.
  

Honeybee solution: a topical RNA solution that targets the Varroa destructor mite, which threatens the role of honeybees in pollinating more than 100 crops annually worth an estimated $18 billion.

• In preparation for submission to the EPA, GreenLight conducted and completed a Tier 2 toxicity study to enable it to better satisfy the data requirements needed under EPA guidance and expects to submit an application for regulatory approval in 2023.
  

Additional plant and animal health programs:

• Confirmatory field trials, at our Seville, Spain, facility and other locations, continue for the Botrytis, Diamondback Moth, and Powdery Mildew programs through 2022.
• In October 2022, GreenLight and Queensland University of Technology (QUT) announced a partnership using an RNA-based solution to tackle destructive Fall armyworm, which causes more than US$2 billion in annual global crop loss.

Third Quarter 2022 Financial Results

• Cash Position: Cash, cash equivalents, and marketable securities were $98.4 million as of September 30, 2022, compared to $31.4 million as of December 31, 2021. The increase was primarily driven by proceeds received from the close of the business combination and concurrent PIPE financing in February as well as the August PIPE financing. This increase was offset in part by cash used to fund operations of approximately $112.1 million since the start of the year.
• Collaboration Revenue: Collaboration revenue was $1.7 million during the third quarter of 2022, compared to none during the third quarter of 2021. This revenue was primarily related to the delivery of intellectual property and research services, including manufacturing technology transfer.
• R&D Expenses: Research and development expenses increased by $7.2 million to $29.9 million during the third quarter of 2022, compared to $22.7 million during the third quarter of 2021. This increase was primarily related to increased program costs related to R&D materials and service fees supporting the commercial-scale engineering run, pre-clinical trial activities, and personnel expenses, as well as facilities costs such as rent and depreciation expenses.
• G&A Expenses: General and administrative expenses increased by $2.9 million to $8.0 million during the third quarter of 2022, compared to $5.1 million during the third quarter of 2021. This increase was primarily related to an increased level of support required for the growth of the research teams and public company requirements.
• Net Loss: The Company’s net loss was $38.2 million for the third quarter of 2022, compared to $29.2 million during the third quarter of 2021.
  

Financial Guidance:

The Company estimates that its cash and equivalents of $98.4 million as of September 30, 2022 will be sufficient to fund planned operating expenses and capital expenditures, through the second quarter of 2023. Alongside recent measures, including a corporate realignment and portfolio prioritization, the Company continues to evaluate a range of opportunities to extend cash runway, including management of program spending, platform licensing collaborations, and potential financing activities.
