The current shift focuses on enhancing their efficacy by addressing the crucial need for robust T cell responses, an apparent bottleneck for broader impact. Vaccinations against tumour antigens that are shared between tumours, or tumour antigens that arise from mutations unique to individual tumours, represent promising strategies.
How significant are the results in terms of advancing TCR-T cell therapy and AMP immunotherapy for the treatment of solid tumours? We have already applied this approach to several important tumour targets where enhancements in TCR-T therapy may lead to important gains in clinical benefit, including mutated KRAS, NY-ESO, and HPV E7 antigens.
The study assessed cynomolgus macaques vaccinated with 12µg of either the first or second-generation vaccine candidate. During challenge with the original SARS-CoV-2 virus, animals vaccinated with CV2CoV were found to be better protected based on highly effective clearance of the virus in the lungs and nasal passages.
In most cancers, the tumour evolves by acquiring mutations that confer growth advantages or resistance to therapies. These neoantigens are identified by T cells of the immune system as foreign proteins and thus trigger an immuneresponse. Neoantigens are recognised as non-self and trigger an immuneresponse.
2 Unmet needs in lung cancer treatment Recent decades have seen significant advancements in lung cancer treatment, especially with the introduction of targeted therapies and immunotherapies, which have notably improved survival rates. These can include anti-tubulin compounds, potentially reducing side effects and improving quality of life.
The applications of mRNA-based therapies in cancer research represent one of the next groundbreaking steps toward improved cancer treatments. While mRNA usage has played several roles in clinical research , oncology researchers in particular are eager to explore the possibilities of mRNA-based cancer vaccines.
Biogen today announced results of a new analysis of immuneresponse to the COVID-19 vaccine among people with multiple sclerosis (MS). Germany and Spain, researchers evaluated blood samples from 322 participants 28-90 days after their last COVID-19 vaccine dose. Using data from the MS PATHS network in the U.S.,
Stem cell transplants have saved patients’ lives time and time again, which led us to launch our own Stem Cell Transplant and Cellular Therapy Program. Stem cell transplants primarily help the immuneresponse through the “graft-versus-leukaemia effect,” and we have to manage the “graft versus host effect.”
One of the oldest and most successful immunotherapies is simpler: a tamed version of a classic vaccine, against the infectious disease tuberculosis (TB). “BCG” is the “treatment” vaccine’s technical name, for Mycobacterium bovis Bacillus Calmette-Guérin. The approach worked.
These connections provide all-too-important ‘reasons to believe’ for further investment and movement into earlier lines of therapy. However, despite this long winter, new approaches, ranging from CD3 bi-specifics, to cell therapies, to cancer vaccines, and more recent novel intracellular mechanisms have started to turn the tide.
There are a few approved therapies for DMD including four exon-skipping drugs and one AAV-microdystrophin drug, which uses a shortened version of dystrophin. AAV-based therapies often can’t be dosed more than once due to concerns about an immuneresponse. Molecular Therapy-Nucleic Acids. Human molecular genetics.
New Phase 1/2 on Novavax’s COVID-19 vaccine candidate NVX?CoV2373 CoV2373 has shown that the therapy generated “robust antibody responses” when used with or without the company’s Matrix?M M adjuvant. The study examined 131 healthy participants aged 18-59 years old.
Anderson Professor of Chemical and Biomolecular Engineering, and his colleagues, are reporting in iScience the event of an intranasal subunit vaccine that gives durable local immunity against inhaled pathogens. A fundamental limitation of intramuscular vaccines is that they’re not designed to elicit mucosal immunity.
More recently, researchers have begun to look at conjugating immunomodulatory agents to antibodies to directly activate an immuneresponse against the tumour. This approach – immune-stimulating antibody conjugates (ISACs) – uses a payload that stimulates the innate and adaptive immuneresponses, recruiting tumour-fighting T cells.
The Phase 1 trial was a randomized, observer-blind, placebo-controlled study to assess the safety, reactogenicity and immunogenicity of the adjuvanted COVID-19 S-Trimer vaccine candidates formulated with different antigen levels. No serious adverse events related to the vaccine candidates studied were reported.
The preclinical results demonstrated significant immuneresponses and tumour regression. Could you elaborate on the mechanisms by which these responses are initiated within cancer cells? This induced anti-tumour immunity is also detectable by increased innate and adaptive immune cells in the tumour, spleen and blood.
Even after microbiologists discovered the bacterium that causes the illness in 1882, it wasn’t until the 1920s that researchers were able to develop a vaccine for TB. These breakthroughs have significantly curbed cases, with vaccination reducing the odds of death by 74 percent. tuberculosis , to develop the vaccine.
25, 2021 — Giving melanoma patients a “personalized” vaccine can prompt an anti-tumor immuneresponse that lasts for years, an early study finds. But it builds on earlier work showing it is possible to spur the immune system to respond to an individual’s unique tumor. MONDAY, Jan.
How does GigaGen’s single-cell discovery and development platform differ from traditional methods of producing polyclonal antibody therapies? Current methods for producing pAb therapies rely on regular plasma donations for their development.
In the unprecedented context of at least 13 variants circulating within the study population subset assessed at this interim analysis, CVnCoV demonstrated an interim vaccine efficacy of 47% against COVID-19 disease of any severity and did not meet prespecified statistical success criteria. About CVnCoV.
In the decades since its identification in 1989, advances in clinical research for new Hepatitis C therapies and the introduction of direct-acting antiviral agents (DAAs) have led to viral eradication in more than 98% of patients, resulting in HCV crossing from manageable to being the first curable , chronic viral infection. Zhao et al.
In a Phase 2/3 clinical trial, the Pfizer-BioNTech COVID-19 Vaccine elicited a strong immuneresponse in this age group Three 3-µg doses had favorable safety profile similar to placebo in young children ages 6 months through 4 years in Phase 2/3 clinical trial Pfizer-BioNTech COVID-19 Vaccine now authorized in the U.S.
Genome engineering and gene therapies that manipulate DNA sequences in cells have driven a biotechnological revolution over the past decade. 9 In addition, host immuneresponses further add to the complexity of developing cell-specific AAV capsids for clinical applications.

Also, last week’s digest had an error: The country that approved the malaria vaccine was Ghana. Vaccines (basically little fat bubbles filled with mRNA and some dissolvable polymers) were physically printed onto microneedle patches using a robot. The patches have little spikes that help push the vaccines through the skin.
