GreenLight Biosciences Outlines Development Strategy and Highlights Portfolio Updates at Human Health R&D Day

  • Progressing human health pipeline conferring mRNA platform advantages for infectious disease and personalized oncology medicines; pursuing capital efficient strategy targeting unmet medical needs, in both the developed and lower- and middle-income countries (LMICs), pairing focused R&D spend with partnerships.
  • Accelerating development of next-generation COVID vaccine candidate; decision to advance universal pan-sarbecovirus vaccine candidate in place of mono-valent Wuhan based antigen.
  • Preclinical data on shingles vaccine candidate(s) showing high and durable antibody response, strong cellular T-cell response, and durable memory response.
  • Collaboration with EpiVax therapeutics to develop personalized mRNA cancer vaccine candidates.
  • R&D Day webcast to begin at 10:30 am ET today.

BOSTON, March 9, 2023 —GreenLight Biosciences (Nasdaq: GRNA), a public benefit corporation striving to deliver on the full potential of RNA to address some of the world’s toughest problems in human health and agriculture, will today outline its pipeline strategy and R&D progress for mRNA-based solutions during its Human Health R&D Day being held today, March 9, 2023 at 10:30 a.m. ET in Lexington, MA.

GreenLight today is sharing the key pillars of its human health strategy:

  • Developing vaccines for infectious diseases, especially those addressing unmet medical needs in lower- and middle-income countries.  Consistent with its public benefit corporation status, Greenlight is striving to support global, sustainable vaccine access and pandemic response readiness. 
  • Developing innovative products to address unmet medical needs in oncology and autoimmune diseases.  This work has begun with the collaboration with EpiVax Therapeutics to co-develop personalized cancer vaccines.
  • Continued advancement of GreenLight’s mRNA technology platform through innovations and to seek potential partnerships with pharmaceutical and biotechnology companies.

As previously announced, GreenLight received approval from the Rwanda Food and Drugs Authority (Rwanda FDA) to initiate a Phase I/II study of its GLB-COV2-043 vaccine booster candidate.  However, given the global shift in the standard of care for COVID vaccination to the Wuhan/Omicron bivalent vaccine, and new availability of the bivalent vaccine in Rwanda, GreenLight has decided to proceed with its pan-sarbecovirus vaccine candidate instead of the GLB-COV2-043 (monovalent) vaccine candidate as originally planned.  GreenLight is accelerating the development of its pan-sarbecovirus vaccine candidate that is potentially capable of broader coverage and predictive protection and plans to make a follow-up filing on this candidate to the Rwanda FDA and the Rwanda National Ethics Committee (RNEC).  GreenLight will be working expeditiously and closely with its Rwandan partners to advance these efforts over the coming months and are starting conversations with potential partners in other countries that have expressed interest in supporting its development and clinical path for a broader pan-sarbecovirus vaccine. “We are excited to advance our pan-sarbecovirus vaccine candidate that may allow us to bring a next generation, innovative Covid-19 vaccine to market in Rwanda, and the rest of the world, earlier than we anticipated,” Andrey Zarur, CEO of GreenLight.

Regarding its shingles program, GreenLight is excited to share promising new pre-clinical data.  GreenLight has selected a lead candidate to progress towards clinical development after evaluation of multiple antigen designs and formulations.  Based on pre-clinical data, our lead pre-clinical candidate induced antibody levels and memory B and T cell responses in mouse in vivo studies similar to the current standard of care.  In addition, the pre-clinical data showed that the lead candidate induced T cell responses in mouse in vivo studies stronger than the current standard of care.  This pre-clinical candidate is advancing towards development candidate nomination.  Serum Institute of India Private Limited will be responsible for the clinical development, manufacturing, and commercialization of the vaccine candidate in lower- and middle- income countries under its license agreement with GreenLight Biosciences.  GreenLight retains the clinical development, manufacturing, and commercial rights in the developed world.

GreenLight and EpiVax Therapeutics are partnering to create a proprietary personalized cancer vaccine platform which combines GreenLight’s mRNA design and manufacturing expertise with EpiVax Therapeutic’s neoantigen discovery platform. “We continue to be excited about expediting the development of personalized cancer vaccines in collaboration with EpiVax Therapeutics.” said Kimberly Warren, Chief Business Officer of GreenLight Biosciences. “While our initial focus will be on bladder cancer, the 4th most common cancer in men, we plan on working to shape a pipeline of compelling personalized cancer vaccine candidates that will help build a future of more timely and accessible treatments.”

The human health R&D Day is the second in a series providing comprehensive updates on GreenLight’s R&D strategy and progress. The previous session, which focused on GreenLight’s Plant Health pipeline, was held on Tuesday, March 7, 2023.

A live webcast of the event will be available live and can be accessed via the Investors section of the Company’s website at www.greenlightbiosciences.com. Registration is available here: https://www.greenlightbiosciences.com/rdshowcase/ and a replay of both events will be available at https://investors.greenlightbio.com for approximately 30 days.
