[vc_row][vc_column]

\n A phase one trial of one of the world\u2019s first multivariant COVID-19 Vaccine has been launched by US pharmaceutical company Gritstone, in collaboration with Manchester University NHS Foundation Trust and The University of Manchester.\n<\/p>\n[\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]Initially involving participants aged 60+, its creators say the drug \u2013 called GRT-R910 \u2013can boost the immune response of first-generation COVID-19 vaccines to a wide array of variants of Sars-Cov-2, which cause COVID-19.<\/p>\n

The trial will take place at the National Institute of Health Research Manchester Clinical Research Facility (NIHR Manchester CRF) at Manchester Royal Infirmary, part of Manchester University NHS Foundation Trust (MFT).<\/p>\n

At MFT, the trial is being delivered by the Research and Innovation Vaccine Team. Andrew Clarke (63), was the first to receive the jab followed by his wife Helen (64). Both are retired, and are from Bolton.<\/p>\n

Also supported by Health Innovation Manchester (HInM), the trial is expected to recruit 20 volunteers, with data evaluating the vaccine expected in the first quarter of 2022. Results from the preclinical studies leading up to the development of the vaccine will be jointly published by Gritstone and the National Institutes of Health (NIH) later in the year.<\/p>\n

Part of Gritstone\u2019s CORAL program, GRT-R910 is a self-amplifying mRNA second generation SARS-CoV-2 vaccine, or SAM for short, which delivers antigens from both the spike and non-spike proteins.<\/p>\n

SAM vaccines, say its creators, may offer the opportunity of lowering vaccine doses or eliminate the need of repeat administrations \u2013 with the potential to safely drive strong, durable and broad immune responses across SARS-CoV-2 variants.<\/p>\n

SAM vaccines work by inducing special immune cells (CD8+ T cells), an important arm of the body\u2019s immune response to viruses, as well as antibodies that can neutralise the virus and prevent it binding to and infecting cells. It is hoped that this will offer potential for robust and persistent immunity, which includes at-risk and older populations.<\/p>\n

\u201cOur SAM COVID-19 vaccine is designed to drive robust CD8+ T cell responses, in addition to strong neutralising antibody responses, offering the promise of longer lasting immunity,\u201d said Andrew Allen, M.D Co-Founder, President and Chief Executive Officer of Gritstone.<\/p>\n

He added: \u201cSince viral surface proteins like the spike protein are evolving and sometimes partially evading vaccine-induced immunity, we designed GRT-R910 to have broad therapeutic potential against a wide array of SARS-CoV-2 variants by also delivering highly conserved viral proteins that may be less prone to genetic variation in the virus.<\/p>\n

\u201cOur hypothesis is that a different vaccine such as GRT-R910 might complement the primary immune response from pre-existing vaccination with a first generation COVID vaccine in such a way that it would provide more benefit than an additional dose of the same vaccine.\u201d<\/p>\n

Professor Andrew Ustianowski, who is Clinical Lead for the NIHR COVID Vaccine Research Programme, Consultant in Infectious Diseases and Tropical Medicine at North Manchester General Hospital (part of MFT) and Honorary Clinical Chair at The University of Manchester, will be the local lead investigator for this study.<\/p>\n

Professor Ustianowski is Chief Investigator for the study and MFT is the chief site.<\/p>\n

He said: \u201cWe now know the immune response to first generation vaccines can wane, particularly in older people. Coupled with the prevalence of emerging variants, there is a clear need for continued vigilance to keep COVID-19 at bay.<\/p>\n

\u201cWe think GRT-R910 as a booster vaccination will elicit strong, durable, and broad immune responses, which are likely to be critical in maintaining protection of this vulnerable elderly population who are particularly at risk of hospitalisation and death.\u201d<\/p>\n

Professor Ian Bruce, from The University of Manchester, is Chair of the Manchester COVID-19 Research Rapid Response Group (RRRG), Consultant Rheumatologist at Manchester Royal Infirmary\u2019s Kellgren Centre, Academic Director at Health Innovation Manchester and Director of the NIHR Manchester Biomedical Research Centre.<\/p>\n

He said: \u201cWe\u2019re tremendously excited that this promising vaccine is to be trialed here in Manchester. As the only European site for this study, it is testament to the way our academic and clinical researchers have come together as part of the \u2018One Manchester R&I\u2019 approach to answer the questions the world needs answers to.<\/p>\n

\u201cThough the vaccine is being trialled in the over 60s, future studies will also examine its efficacy in other-vulnerable populations.<\/p>\n

\u201cIf successful, we feel it has the potential to have play a significant role in the battle against COVID-19, which has so devastated vulnerable populations across the globe.<\/p>\n

\u201cWe look forward to working with Gritstone in the clinical development of this promising next generation COVID-19 vaccine.\u201d<\/p>\n

The study will examine dose, safety, tolerability, and immunogenicity of GRT-R910 at two dose levels at least four months after the second administration of their initial vaccine.<\/p>\n

GRT-R910 is also being investigated as part of a US National Institute of Health sponsored Phase 1 study.<\/p>\n

Additional trials of the CORAL platform, including an additional Phase-1 trial are also planned, which will inform the future development of CORAL, Gritstone\u2019s SARS-COV-2 second generation vaccine programme.<\/p>\n

Andrew Clarke, said: \u201cWe signed up to the NIHR COVID-19 Vaccine Registry last summer as we had a general desire to be helpful.\u201d<\/p>\n

Helen Clarke said: \u201cI used to work in the NHS and had been involved in research as a nurse in the past.<\/p>\n

\u201cWe\u2019ve been amazed how quickly a vaccine was made and approved and that couldn\u2019t happen without volunteers.\u201d<\/p>\n

Andrew added: \u201cSomebody has to be the first and we\u2019re confident in the science and technology behind this vaccine and convinced of the need for it.<\/p>\n

\u201cBecause we\u2019re both retired, we feel we had a reasonably easy lockdown, but we know it wasn\u2019t the same for everybody. We feel that this is perhaps a small part we can play in helping to make things change.\u201d[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
