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, Mass., Feb. 01, 2023 (GLOBE NEWSWIRE) -- GreenLight Biosciences, Inc. (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.

Notes to editors
- 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.
- 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.

- Platform Life Sciences, in collaboration with GreenLight and leading clinical investigators in Rwanda, will conduct the trial.
