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.

GreenLight Biosciences receives approval to initiate Phase I/II clinical trial of Covid-19 mRNA vaccine candidate 

  • The Rwanda FDA has given regulatory approval to GreenLight to start a Phase I/II clinical trial of its Covid-19 vaccine candidate in Rwanda. 
  • This phase I/II clinical trial is the first step in GreenLight’s integrated strategy of bringing a universal Covid-19 mRNA vaccine to market globally. 
  • By initiating this first-in-human clinical study in Rwanda, GreenLight is demonstrating its commitment to partner with the people of Africa in bringing advanced health technologies to the continent. 

Kigali, Rwanda, and Lexington, MA February 1, 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, today announced that it has received regulatory approval from the Rwanda Food and Drugs Authority (Rwanda FDA) to start a Phase I/II clinical trial of its vaccine candidate against Covid-19, as a booster to previously vaccinated individuals. Preparations for the trial are underway. 

Mark Dybul, chair of GreenLight’s Human Health Scientific Advisory Board, and former executive director of the Global Fund to Fight AIDS, Tuberculosis and Malaria, said: 

 
“Covid-19 continues to be a significant global health issue. Efforts to develop novel vaccines that are longer-lasting and effective against a broad spectrum of variants are necessary to minimize the risk of disease resurgence or dangerous mutations of the SARS-CoV-2 virus.  It is especially important to develop vaccines that are globally affordable and scalable. GreenLight’s efforts to initiate this clinical study in Rwanda show the company’s commitment to support Africa’s goal of affordable vaccine self-sufficiency. 

Andrey Zarur, GreenLight’s CEO, said: 

“This clinical trial marks the necessary first step toward developing an integrated, universal strategy against Covid-19. Our previously announced collaboration with the U.S. National Institutes of Health to develop a universal Covid-19 vaccine, and our previously reported scalable mRNA manufacturing process, will enable us to address this disease in a more effective manner.” 

“We are delighted to receive approval from the Rwanda Food and Drugs Authority to start our Covid-19 mRNA vaccine candidate trial. Approval to begin clinical trials in humans, from a national regulatory authority, is a significant milestone for GreenLight’s human health business. This demonstrates our commitment of supporting vaccine and therapeutics accessibility for low- and middle-income countries.”  

We share the Rwandan government’s vision that everybody should have access to the best healthcare. A Phase I/II trial of our Covid-19 vaccine candidate is just the start. Rwanda is at the forefront of bringing end-to-end research and development to Africa. We look forward to deepening our partnership so that we can play our part, and help Africa become self-sufficient in vaccines.” 

In addition to its mRNA Covid-19 vaccine candidate, GreenLight is developing mRNA vaccines against other infectious diseases, such as shingles (in collaboration with Serum Institute of India Pvt. Ltd.), and cancer (in collaboration with EpiVax Therapeutics), as well as RNA-based therapies against genetic disorders, such as sickle-cell disease.  Further details of the Covid-19 vaccine candidate study can be found at: https://www.clinicaltrials.gov/ct2/show/NCT05602961

Notes to editors 

  1. GreenLight’s mRNA vaccine candidate, GLB-COV2-043, contains mRNA, encoding the SARS-CoV-2 full-length spike protein from the Wuhan strain, formulated in a lipid nanoparticle. This vaccine candidate is part of GreenLight’s broader Covid-19 strategy, which includes the development of a universal Covid-19 vaccine with broader and more durable protection. Pending positive safety and immunogenicity results from this Phase I/II clinical trial, GreenLight will look to continue development in Africa on potential next-generation Covid-19 vaccine candidates. 
  2. The Phase I/II study is designed to assess safety and immunogenicity as measured by humoral and cellular immune-response endpoints. Enrollment will be open to eligible adults who have received a 2-dose priming course of the mRNA BNT162b2/Comirnaty vaccine or a 2-dose priming and a third injection (i.e. as a booster) of the same mRNA vaccine. Participants will be evaluated in four cohorts, with the GreenLight vaccine candidate being administered in 15 microgram, 30 microgram, 60 microgram and 90 microgram doses, respectively. Each cohort will include 10 participants receiving the GreenLight vaccine candidate. 
  3. Further details on GreenLight’s pipeline and plans can be found at investors.greenlightbio.com. 
  4. Platform Life Sciences, in collaboration with GreenLight and leading clinical investigators in Rwanda, will conduct the trial.

GreenLight Biosciences and Queensland University of Technology partner to tackle destructive fall armyworm using RNA

● GreenLight Biosciences and Queensland University of Technology (QUT) partner to create a solution for fall armyworm


● Fall armyworm is one of the most destructive insect pests on the planet, causing more than US$2 billion in annual crop loss worldwide


● The Australian government has been searching for a more environmentally-friendly solution to fall armyworm and is supporting the partnership with a AUD$400,000 grant

BOSTON, MA, and BRISBANE, Australia, October 5, 2022—Researchers from Boston’s GreenLight Biosciences and the Queensland University of Technology (QUT) in Brisbane, Australia, have announced an agreement to develop a solution to fall armyworm, which causes more than US$2 billion in annual global crop loss.

The partnership includes an Australian government grant to QUT of more than AUD$400,000  from the Australian Research Council. It brings together the teams of two preeminent researchers, Dr. Julia Bally and Professor Peter Waterhouse from the QUT Centre for Agriculture and the Bioeconomy, and GreenLight’s Plant Health research and development team.

The partnership aims to develop a solution for fall armyworm, a pest of national priority in Australia. It is also a point of emphasis that the project delivers environmentally-friendly crop protection tools against fall armyworm.

GreenLight’s plant health division is working on producing RNA-based solutions for a variety of fungi and insects that cause massive food loss and crop damage annually. In lab tests and field trials, GreenLight’s RNA-based solutions leave low or no residues.

Dr. Bally said previous collaboration on fall armyworm with GreenLight had been important to securing the grant from the Australian Research Council this year.

“We are excited to work with GreenLight Biosciences on this solution to armyworm,” she said. “We believe furthering our partnership will generate comprehensive new technologies to fight against one of the most damaging global crop pests and greatly improve Australian agritech capacity and strengthen international collaborations.”

GreenLight’s Vice President of Plant Health R&D Ron Flannagan said: “Fall armyworm has recently invaded Australia and devastates many crops, including sorghum and cotton. Our RNA platform allows us to develop solutions faster and more efficiently than was previously possible. So we are delighted to partner with QUT to accelerate our work targeting the fall armyworm with a sustainable solution.”

The project will begin with lab studies and advance to greenhouse and field trials.

“We believe this research will provide significant benefits, such as added security for Australia’s most important agricultural crops and regions and global food production,” Dr. Bally said.

International crop network validates ledprona as a new Mode of Action group

An effective and novel pest-management solution with low-to-no residues aimed at the Colorado potato beetle (CPB) has received validation as a new mode of action (MoA) by the Insecticide Resistance Action Committee.

Ledprona, the active ingredient in GreenLight’s CalanthaTM product, was approved as a new mode of action in the recent winter meeting of IRAC, an international association of crop-protection companies that focuses on resistance management and sustainable agriculture.

The first foliar-applied, dsRNA-based bioinsecticide that provides effective control of CPB, CalanthaTM is expected to be registered in the United States this year. The Colorado potato beetle (Leptinotarsa decemlineata) ravages plants like potatoes and eggplant and accounts for more than $500 million in annual crop loss worldwide. 

For decades, insect resistance to pesticides has challenged growers. Using integrated pest management, which includes rotating insecticides, farmers and agronomists can prolong the useful lifespan of crop treatments. GreenLight’s product is designed to work well with standard growers’ programs to control first- and second-generation Colorado potato beetle infestations.

CalanthaTM has a unique mode of action among chemical and biological insecticides, which will provide farmers with a new tool aimed at protecting potato and eggplant fields from the Colorado potato beetle and support their efforts at resistance management. 

Ledprona, expected to be classified as IRAC MoA group 35 (RNAi-mediated targeted suppressors), specifically targets only CPB, causing the beetle to stop eating and expire from accumulation of its own metabolic waste. Because it is based on double-stranded ribonucleic acid, CalanthaTM degrades quickly in the environment, supports biodiversity, and is an example of the next generation of eco-friendly crop-protection products. 

The Insecticide Resistance Action Committee helps growers around the world by developing mode-of-action classification schemes; identifying new technologies for insect, mite, and tick control products; and  implementing insecticide resistance management strategies for crop protection, plant biotechnology, and public health.
