Adjuvanted S-Trimer COVID-19 vaccine candidates demonstrated favorable safety and tolerability profiles and strong neutralizing immuneresponses in a phase 1 trial.
The phase 1 clinicaltrial was a randomized, double-blind and placebo-controlled study in 150 adult and elderly participants.
German drugmaker CureVac said preclinical studies of its COVID-19 vaccine candidate, CVnCoV, showed the vaccination prompted a successful immuneresponse. The messenger RNA-based vaccine, which is designed to block replication of the coronavirus, was shown to induce neutralizing antibodies and activate T-cells in hamsters and mice.
Natural killer (NK) cells are another immune cell type that, as the name suggests, also have potent cell-killing activity, and have a well-known role in the anti-tumour immuneresponse. In the context of a tumour microenvironment, Tregs are often present in high numbers, preventing an effective immuneresponse to the tumour.
Strong Th1 cell-mediated immuneresponses were also observed for the vaccine candidates with either adjuvant. Clover intends to initiate a separate pivotal clinicaltrial of the S-Trimer vaccine candidate in combination with Dynavax’s advanced CpG 1018 adjuvant plus alum in the first half of 2021.
Immunization of non-human primates (rhesus macaques) with BNT162b2, a nucleoside-modified messenger RNA (modRNA) candidate that expresses the SARS-CoV-2 spike glycoprotein, resulted in strong anti-viral effects against an infectious SARS-CoV-2 challenge. producing CD8+ T cell responses, which is thought to promote an anti-viral effect.
As soon as I learned about DNA and RNA, I wanted to be a molecular biologist. Last stops at RNA My last roles in biotech were where my original passion began: DNA and RNA. My last stop at Arrakis Therapeutics is with a company targeting RNA with small molecules. I wanted to use molecular biology to create drugs.
The Coalition for Epidemic Preparedness Innovations (CEPI) will continue to support the development of Clover’s COVID-19 vaccine candidate and will fund the development, including the Phase 2/3 trial, through licensure. Dynavax developed CpG 1018 to provide an increased vaccine immuneresponse, which has been demonstrated in HEPLISAV-B.
The vaccine candidate chosen for first clinical development, CVnCoV, is an optimized, non-chemically modified mRNA, encoding the prefusion stabilized full-length spike protein of the SARS-CoV-2 virus, and formulated within Lipid Nanoparticles (LNPs). Phase 1 and 2a clinicaltrials of CVnCoV began in June and September 2020, respectively.
The Phase 1 interim analysis showed that mRNA-1273 was generally well-tolerated across all age groups and induced rapid and strong immuneresponses against SARS-CoV-2. mRNA-1273 is currently being studied in a Phase 3 randomized, 1:1 placebo-controlled trial of 30,000 participants at the 100 µg dose level in the U.S.
The vaccine targeted both the inner nucleocapsid (N) and the outer spike (S) proteins of the virus to maximize the immuneresponse. The study showed this broad immuneresponse led to the complete clearance of the virus in a matter of days after infection of previously-vaccinated primates.
13, 2021 — A single-shot COVID-19 vaccine from Johnson & Johnson has shown very strong results in early clinicaltrials, potentially providing a significant boost to U.S. The vaccine produced an immuneresponse of all 805 clinicaltrial participants within two months of inoculation, according to results published Jan.
As research developments into RNA vaccines help scientists accelerate drug candidates to arm the immune system against coronavirus, Pharma IQ ’s Keeping tabs on Covid-19 update returns with news from some of the biotechnology innovators leading the fight against the global pandemic.
Our research demonstrated that GDF-15 acts as a versatile tool for tumours to inhibit the mounting of an effective antitumoral immuneresponse at various steps of its process, including antigen presentation, immune cell activation, and their migration and infiltration into the tumour. in North America) in late 2017.
Fitusiran is an investigational, subcutaneously administered small interference RNA therapy in development for the treatment of people with hemophilia A or B, with or without inhibitors and has the potential to transform treatment as it would be the only prophylactic therapy with as few as six injections per year.
At the Broad, he decided to focus on myeloid cells, which make up to half of the cells in many brain tumors and can suppress the immune system, preventing immunotherapies from working well. To do this, the team used a different approach to single-cell analysis.
CRISPRoff silences the targeted gene by adding methyl groups, chemical tags that prevent the gene from being transcribed or read into RNA and so from being expressed as protein. ZFPs are also common in human cells, meaning they are less likely to trigger an immuneresponse against themselves than the bacterial Cas9.
By then, a few cancer immunotherapies had entered clinicaltrials and only a handful had been approved by the FDA. As a first step, Manguso set his sights on treatments called PD-1 checkpoint inhibitors, which at the time had shown tremendous promise in clinicaltrials and would receive their first FDA approval in 2014.
Early-phase clinicaltrials have shown the safety and efficacy of using stem cells for cardiac repair, encouraging further research and development. RNA-based therapies, including mRNA and RNA interference (RNAi), are being explored to modulate gene expression in heart cells.
By Allessandra DiCorato May 1, 2024 Credit: Ricardo Job-Reese, Broad Communications The health benefits of exercise are well known but new research shows that the body’s response to exercise is more complex and far-reaching than previously thought. Whole-body analysis Conducting such a large and detailed study required a lot of planning.
Scientists from the Massachusetts Institute of Technology (MIT) and the University of Massachusetts Medical School (UMass), US, have collaborated to create a novel type of nanoparticle that can deliver messenger RNA that encodes for beneficial proteins to the lungs.
The Moderna vaccine is similar to Pfizer and BioNTech’s vaccine in the sense that they both use an approach utilizing messenger RNA (mRNA). Instead, it uses a genetic code, which tricks the body into developing an immuneresponse to the virus.
The Moderna COVID-19 Vaccine contains messenger RNA (mRNA), which is genetic material. After a person receives this vaccine, their body produces copies of the spike protein, which does not cause disease, but triggers the immune system to learn to react defensively, producing an immuneresponse against SARS-CoV-2.
In one experiment, the microneedle patches were used to deliver a SARS-CoV-2 vaccine into mice, producing immuneresponses similar to a traditional injection. Printed vaccines caused mice to have a faster immuneresponse. Read An easier (and cheaper) way to do single-cell RNA sequencing? Synthetic Biology.

A sidebar here: secondary lymphoid organs include spleen, lymph nodes, and Peyers patches and are characterized by critical structural features that include a T cell zone and adjacent B cell follicles that orchestrate coordinated immuneresponses, for example, to pathogens. focused on ICB response in melanoma ( [link] ).
The company announced positive top-line results from the SURPASS-4 Phase 3 clinicaltrial of tirzepatide in adults with type 2 diabetes, evaluating A1C and body weight reductions from baseline. The trial compared tirzepatide to insulin glargine in adults with type 2 diabetes and increased cardiovascular risk.
BNT111 is the lead product candidate from BioNTech’s FixVac platform that targets a fixed combination of mRNA-encoded, tumor-associated antigens with the objective of triggering a strong and precise immuneresponse against cancer and is fully owned by BioNTech.
But, regardless of which was first, they all operated with the same core data as their mechanism for understanding life: messenger RNA ( mRNA ). Their pipelines were bursting with promising candidates, and their success rates in clinicaltrials were astronomical compared to the industry standard of just a few years back.
The interim results from the phase 2 trial on the vaccine, published today, on the contrary, showed a “ strong neutralizing antibody response” ? The companies also noted a high immuneresponse after a single dose of the shot in patients with prior infection, indicating, they said, strong booster potential for the jab. “
Even with the holidays among us, there were a number of clinicaltrial announcements. Vir Biotechnology and GlaxoSmithKline dosed the first patient in a new sub-trial of a Phase III study of monoclonal antibody VIR-7831 for hospitalized adults with COVID-19. Here’s a look. COVID-19-Related.
DNA and RNA molecules are also built from exclusively right-handed nucleic acids. Across the tree of life, organisms strictly require exactly one of the two chiral forms of their molecular building blocks — amino acids, nucleotides of RNA and DNA. 4 As far as we know, right-handed proteins never occur naturally.
Skin microbes can trigger strong immuneresponses. These microbes were engineered to express tumor antigens that could “elicit T cells that were licensed by the commensal immune program but specific for a tumor,” including both CD4+ and CD8+ T cells, according to the study. Molecular Therapy. Arieta C.M.
Fortunately, some novel preventatives and therapies are in the works, including a vaccine equipped with adjuvants that efficiently prime the immune system and newer antibiotics against which the bacteria have yet to evolve resistance. A phase 3 clinicaltrial for M72/AS01E, funded by the Gates Foundation, began this year.
More specifically, the agency requires that scientific evidence for regulatory approval must come from large, high quality clinicaltrials that are randomized and observer-blinded, with an expectation of appropriately designed studies with significant numbers of participants across diverse populations.
