Activated PMN exosomes are pathogenic entities that cause destruction in the COPD lung
The University of Alabama at Birmingham researchers have found a novel, previously unreported pathogenic entity that is a fundamental link between chronic inflammation and tissue destruction in the lungs of patients with chronic obstructive pulmonary disease, or COPD. COPD is the fourth-leading cause of death in the world.
This pathogenic entity—exosomes from activated polymorphonuclear leukocytes, or PMNs—caused COPD damage when the small, subcellular particles, collected from purified PMNs, were instilled into the lungs of healthy mice. Remarkably, the UAB researchers also collected exosomes from the lung fluids of human patients with COPD and the lung fluids of neonatal ICU babies with the lung disease bronchopulmonary dysplasia; when those human-derived exosomes were instilled into the lungs of healthy mice, they also caused COPD lung damage. Damage was primarily from PMN-derived exosomes from the human lungs.

BGN Technologies Announces Research Collaboration Agreement with ECOIBÉRIA in the Field of Plastic Recycling by Bacteria

BGN Technologies | November 05, 2020

BGN Technologies, the technology transfer company of Ben-Gurion University of the Negev (BGU), announced today that it had signed a research collaboration agreement with ECOIBÉRIA in the field of plastic recycling by bacteria, based on research from the team of Prof. Ariel Kushmaro and Prof. Alex Sivan, both from the Laboratory of Environmental Biotechnology and Avram and Stella Goldstein-Goren Department of Biotechnology Engineering at BGU. Polyethylene terephthalate (PET) is the most abundantly used polymer in the world, with multiple applications in the textile industry as well as in food and beverage packaging. It is estimated that about 56 million tons of PET are produced yearly worldwide, mostly as single use packaging material. Therefore, intense efforts are directed towards recycling and reuse of the PET plastic materials. Prof.'s Kushmaro and Sivan and their team have been studying plastic biodegradation and have discovered several bacteria species that are able to biodegrade polyethylene, which was previously considered a non-biodegradable plastic mainly because of the highly stable carbon−carbon (C−C) bonds of the polymer backbone. Based on these findings, the research collaboration project will assess the biodegradation of PET by previously identified bacteria as well as novel ones, with the aim of developing an efficient biodegradation process of PET whose products will be used as raw materials for recycled PET in the future.

BOLD-100 Outperforms Remdesivir Head-to-Head in SARS-CoV-2 (COVID-19), the only highly potent antiviral agent

PR Newswire | August 18, 2020

Bold Therapeutics, a clinical-stage biopharmaceutical company, recently generated additional data supporting rapid clinical development of BOLD-100 as a novel antiviral. In a series of experiments conducted by Dr. Stephen Barr, Associate Professor in the Department of Microbiology and Immunology at Western University, both BOLD-100 and remdesivir were tested head-to-head in a cytopathic effect assay against a live Wuhan strain of SARS-CoV-2 (COVID-19) in Vero E6 cells. Consistent with prior experiments, BOLD-100 showed low nanomolar IC50 values, a magnitude lower (1/10th) than the IC50 values of Gilead's remdesivir, the only currently approved therapeutic for COVID-19. This data clearly demonstrates that BOLD-100 is a highly potent antiviral agent.BOLD-100 is a first-in-class ruthenium-based small molecule drug which selectively inhibits stress-induced upregulation of the chaperone protein GRP78. In cancer, GRP78 plays a critical role in resistance, survival and proliferation, whereas in viral infections, GRP78 plays a critical role in host recognition, viral entry and viral replication. There are now more than two hundred independent academic articles highlighting the critical role that GRP78 plays in viral infections (e.g. Ha DP, Van Krieken R, Carlos AJ, Lee AS. The stress-inducible molecular chaperone GRP78 as potential therapeutic target for coronavirus infection. J Infect. 2020 Sep;81(3):452–82.).

Gritstone bio and CEPI Expand Vaccine Agreement to Tackle Omicron Variant

Gritstone bio | December 07, 2021

Gritstone bio, Inc. a clinical-stage biotechnology company developing next generation cancer and infectious disease immunotherapies, and CEPI, the Coalition for Epidemic Preparedness Innovations, announced the expansion of their agreement in order to support the development of a self-amplifying mRNA vaccine designed to tackle the Omicron COVID-19 variant. CEPI will provide up to $5 million in additional funding to conduct a Phase 1 clinical trial of Gritstone’s Omicron vaccine candidate in South Africa, where a CEPI-funded clinical trial of Gritstone’s Beta variant COVID-19 vaccine is due to begin shortly. The SARS-CoV-2 T cell epitopes administered within Gritstone’s SAM COVID-19 vaccines are minimally impacted by mutations found within the Omicron variant, reinforcing the platform’s potential to address both Omicron and future variants of concern. CEPI is already funding up to $20.6 million to support preclinical studies, manufacturing process optimization, and a Phase 1 trial of Gritstone’s Beta variant vaccine candidate which will be initiated by South Africa’s University of the Witwatersrand in the coming weeks. The funding announced today will expand the Phase 1 trial to include additional arms to evaluate an Omicron-specific version of the vaccine. Gritstone has commenced manufacturing its SAM vaccine to specifically target the Omicron variant, and the Omicron arms of the Phase 1 trial are expected to begin in Q2 2022, subject to regulatory approval. The recently described Omicron variant, first identified in South Africa on November 9, 2021, was designated a variant of concern by the World Health Organization (WHO) on November 26, 2021. Early evidence suggests that Omicron carries an increased risk of re-infection, and sequence analysis has revealed many mutations in Spike, which may reduce clinical effectiveness of existing vaccines and/or therapeutic antibodies. Enabling equitable access CEPI is committed to global equitable access to COVID-19 vaccines so, through this agreement, CEPI and Gritstone have agreed that this Omicron vaccine candidate will be made available to the COVAX Facility for procurement and allocation, if it is proven to be safe and effective. The COVAX Facility aims to deliver equitable access to COVID-19 vaccines for all countries, at all levels of development, that wish to participate. “While key questions are yet to be answered about Omicron, its transmissibility, and its potential ability to evade our current vaccines, the stakes are too high to delay developing Omicron-specific vaccine candidates. Given the uncertainties, we must accelerate crucial R&D so vaccines are available to tackle Omicron as soon as possible – just in case we need them. There is no time to lose, so I’m pleased that within 10 days of Omicron being declared a Variant of Concern by the WHO, CEPI is expanding its partnership with Gritstone to support a new Omicron vaccine candidate which can be made globally accessible through COVAX.” Dr Richard Hatchett, CEO of CEPI “Our vaccine platforms are built on the premise that a best-in-class vaccine against a virus will drive strong neutralizing antibodies directed to surface antigens such as Spike, and strong cytotoxic T cell responses against other conserved viral antigens to eliminate virally infected cells. This broad immune response would, in principle, provide superior protection against a virus that is mutating its surface protein. Omicron is an example of a novel SARS-CoV-2 variant that may escape clinical protection conferred by vaccines that only afford narrow, Spike-specific immunity,” said Andrew Allen, M.D., Ph.D., co-founder, president and chief executive officer of Gritstone. “Our SAM technology provides an innovative platform likely capable of delivering on the attractive concept of broad, durable immunity. We are thrilled to be quickly expanding our relationship with CEPI in our shared goal of finding new vaccine solutions to battle this deadly virus on a global scale and help prevent current and perhaps future COVID outbreaks.” Self-amplifying mRNA vaccines As with the mRNA-based COVID-19 vaccines that are now in global use, self-amplifying mRNA vaccines use the body’s own machinery to make antigenic protein itself rather than injecting the antigen directly into the body. However, in self-amplifying mRNA vaccines, viral RNA is adapted in a way that allows only the genetic sequence for a specific antigen to be expressed, while keeping the part of the RNA that allows it to produce multiple copies of itself—the self-amplification machinery. The benefit of this approach is that the dose of RNA can be reduced while maintaining the potency of the vaccine. Gritstone’s vaccine candidate may also elicit T-cell immune responses against non-Spike gene fragments, which are slower to mutate than the genes associated with the SARS-CoV-2 Spike protein and could potentially provide broad protection against other SARS-CoV-2 strains. About CEPI CEPI is an innovative partnership between public, private, philanthropic, and civil organisations, launched at Davos in 2017, to develop vaccines against future epidemics. Prior to COVID-19 CEPI’s work focused on developing vaccines against Ebola virus, Lassa virus, Middle East Respiratory Syndrome coronavirus, Nipah virus, Rift Valley Fever virus and Chikungunya virus – it has over 20 vaccine candidates against these pathogens in development. CEPI has also invested in new platform technologies for rapid vaccine development against unknown pathogens. During the current pandemic, CEPI initiated multiple programmes to develop vaccines against SARS-CoV-2 and its variants with a focus on speed, scale and access. These programmes leverage the rapid response platforms developed by CEPI’s partners prior to the emergence of COVID-19 as well as new collaborations. The aim is to advance clinical development of a diverse portfolio of safe and effective COVID-19 candidates and to enable fair allocation to these vaccines worldwide through COVAX. CEPI’s 5-year plan lays out a $3.5 billion roadmap to compress vaccine development timelines to 100 days, develop a universal vaccine against COVID-19 and other Betacoronaviruses, and create a “library” of vaccine candidates for use against known and unknown pathogens. About the CORAL Program Gritstone’s CORAL program is a second-generation SARS-CoV-2 vaccine platform delivering spike and additional SARS-CoV-2 T cell epitopes, offering the potential for more durable protection and broader immunity against SARS-CoV-2 variants. Delivery vectors can comprise a chimpanzee adenovirus, self-amplifying mRNA or both (mix and match). The program is supported by several key relationships: Bill & Melinda Gates Foundation, National Institute of Allergy and Infectious Disease (NIAID), and the Coalition for Epidemic Preparedness Innovations (CEPI). An ongoing Gritstone-sponsored Phase 1 trial is evaluating SAM as a boost and immunogenicity enhancer of AstraZeneca's first-generation COVID-19 vaccine AZD1222 (Vaxzevria) in healthy adults ≥ 60 years in the UK. A two-dose SAM regimen is also being evaluated in an ongoing clinical trial sponsored by the National Institute of Health (NIH) Division of Microbiology and Infectious Disease and in the Coalition for Epidemic Preparedness Innovations-funded, Gritstone-sponsored clinical trial in South Africa expected to begin by year end 2021. About Gritstone Gritstone bio, Inc. a clinical-stage biotechnology company, is developing the next generation of immunotherapies against multiple cancer types and infectious diseases. Gritstone develops its products by leveraging two key pillars—first, a proprietary machine learning-based platform, Gritstone EDGETM, which is designed to predict antigens that are presented on the surface of cells, such as tumor or virally-infected cells, that can be seen by the immune system; and, second, the ability to develop and manufacture potent immunotherapies utilizing these antigens to potentially drive the patient’s immune system to specifically attack and destroy disease-causing cells. The company’s lead oncology programs include an individualized neoantigen-based immunotherapy, GRANITE, and an “off-the-shelf” shared neoantigen-based immunotherapy, SLATE, which are being evaluated in clinical studies. Within its infectious disease pipeline, Gritstone is advancing CORAL, a COVID-19 program to develop a second-generation vaccine, with support from departments within the National Institutes of Health (NIH), the Bill & Melinda Gates Foundation, the Coalition for Epidemic Preparedness Innovations (CEPI) and through a license agreement with La Jolla Institute for Immunology (LJI). Additionally, the company has a global collaboration for the development of a therapeutic HIV vaccine with Gilead Sciences. About COVAX COVAX, the vaccines pillar of the Access to COVID-19 Tools Accelerator, is co-convened by CEPI, Gavi, the Vaccine Alliance Gavi) and the World Health Organization – working in partnership with UNICEF as key implementing partner, developed and developing country vaccine manufacturers, the World Bank, and others. It is the only global initiative that is working with governments and manufacturers to ensure COVID-19 vaccines are available worldwide to both higher-income and lower-income countries.
