Food and Drug Administration (FDA)-approved gene therapy for the treatment of Duchenne muscular dystrophy (DMD). Sarepta’s team is exploring adding sirolimus — a well-established immunosuppressive medication — to the regimen in a way that might enable a greater degree of control over the patient’s immuneresponse.
This update comes after two cases of fatal acute liver failure (ALF) were reported in non-ambulatory DMD patients who received Elevidys, a phenomenon that underscores the ongoing complexities and safety signals related to adeno-associated virus (AAV)-mediated gene therapy. Chief Medical Officer and Head of Global Product Development at Roche.
.” Four years earlier, in 2019, Gray had become the first patient with sickle cell anemia — a genetic disorder that causes red blood cells to become sticky and rigid — to receive an experimental treatment using CRISPR genome editing. Collectively, these repeat-protospacer regions are known as CRISPR arrays.
Glioblastoma (GBM), an aggressive brain cancer, is notoriously resistant to treatment, with recurrent GBM associated with survival of less than 10 months.
The Expanding Role of mRNA in Cancer Therapy One of the most exciting applications of mRNA therapeutics lies in cancer treatment, where leveraging the immune system to target tumors offers a novel approach. This process triggers a robust immuneresponse, enabling the immune system to recognize and attack cancer cells.
Targeted drug treatment leads tumor cells to imitate viral infection By Ari Navetta July 11, 2024 Breadcrumb Home Targeted drug treatment leads tumor cells to imitate viral infection Exploiting "viral mimicry," mIDH1 inhibitors trick tumors into thinking they are infected with a virus.
Better activation of innate and adaptive immuneresponses was achieved with CV2CoV, resulting in faster response onset, higher titers of antibodies, and stronger memory B and T cell activation as compared to the first-generation candidate, CVnCoV.
The use of nanoparticles, which are around the size of a virus particle, is a very promising delivery method for overcoming chemotherapy issues. La-Beck explained: “The thing that’s really attractive with using a nanoparticle in cancer treatments is that the nanoparticle is much larger than chemotherapy molecules.”
Moderna has announced that its coronavirus vaccine candidate has shown promise in generating an immuneresponse in elderly patients in an early-stage clinical trial. . The company has already tested the treatment on 10 adults between the ages of 56-70, and 10 over 71. million.
Adjuvanted recombinant COVID-19 vaccine candidate triggered strong neutralizing antibody responses in all adult age groups. High immuneresponse after a single dose in patients with prior infection shows strong booster potential. GSK is also exploring potential therapeutic or treatment options for COVID-19 patients.
This study, conducted using human cancer cells grown in a lab and mouse models mimicking human breast and lung cancer, revealed that the biomolecule treatment notably reduced tumour growth and increased survival rates. Tender elaborated that these results in immune cells ignoring the cancer rather than eliminating it, as they normally would.
HLA are the critical molecules that our immune systems use to present peptides to T cells and facilitate recognition and killing in immuneresponses to pathogens. HLA-II presents peptides to CD4 T cells thought to be important for indirectly helping immuneresponses and facilitating antibody production.
The molecular tools of CRISPR were borrowed and developed from the natural immuneresponse of bacteria to viruses – bacteriophages – that infect them. But will it, can it, improve upon nature? But emulating a microbiome, a complex assortment of cells and viruses, is, I think, a technically more challenging venture.
These data reinforce the potential function of a third dose of the vaccine in maintaining high levels of protection against the virus in this age group. The neutralizing GMT against the wild-type virus was 2153 (after three doses), compared to 335 after two doses.
Treatment is being developed by Australian biotech Ena Respiratory.

In the study, immunization with the hAd5-COVID-19 vaccine inhibited SARS-CoV-2 virus replication in 100% (10 of 10) of Rhesus macaques, with a drop in viral replication starting on the first day of vaccine administration, and undetectable viral levels as early as three to five days post-challenge in most of the animals.
We had built a machine learning classifier that has been trained to identify amino acid sequences that have the potential to mimic ‘host defense peptides’ from the human innate immune system. Such peptides play a critical role in the machinery for amplifying innate immuneresponses. This work can potentially help with that also.
. “We continue to see the strongest effects in patients who are most at risk for poor outcomes due to high viral load, ineffective antibody immuneresponse at baseline, or pre-existing risk factors. In the overall patient group with detectable virus at baseline, the average daily reduction in viral load through day 7 was a 0.36
The outcome confirms that only one single case was attributable to the original SARS-CoV-2 virus. “In addition, the variant-rich environment underlines the importance of developing next-generation vaccines as new virus variants continue to emerge.” More than half of the cases (57%) were caused by Variants of Concern.
S, prevented severe clinical disease in Syrian golden hamsters, upon challenge with SARS-CoV-2, the virus that causes COVID-19 in people. Four weeks later, the animals were exposed to a high dose of SARS-CoV-2 virus. Janssen’s lead SARS-CoV-2 investigational vaccine candidate, Ad26.COV2.S, Mortalities were absent in vaccinated animals.
The trial will evaluate the safety and immunogenicity of a monovalent flu vaccine candidate coding for the hemagglutinin protein of the A/H3N2 strain of the influenza virus. Additionally, the platform may be applied to various classes of treatments, such as therapeutic antibodies or protein degradation.
The data demonstrate that a single dose of JNJ-78436735 induced a strong neutralizing antibody response in nearly all participants aged 18 years and older and was generally well-tolerated. Immuneresponses were similar across the age groups studied, including older adults. ImmuneResponse Data.
New Phase 2 study assesses potential for refined antigen formulation to achieve optimal immuneresponse, including in older adults. GSK’s response to COVID-19 has been one of the broadest in the industry, with two potential treatments in addition to our vaccine candidates in development.
Next Generation AAVs enhance gene therapies by increasing transduction efficiency and specificity while reducing immuneresponses and cost.

Clinical trial to assess safety, immuneresponse and reactogenicity, after preclinical data showed high neutralizing antibody levels. Additionally, the platform may be applied to various classes of treatments, such as therapeutic antibodies or protein degradation.
Another promising strategy is drugs that target the proteins within human cells that the virus needs to infect, multiply, and spread. These studies narrowed the list to 73 human proteins that the virus depends on to replicate. That’s the strategy employed by remdesivir , the only antiviral drug currently authorized by the U.S.
The public health relevance of the refrigerator temperature-stable adjuvanted protein-based Sanofi-GSK vaccine is strongly supported by the induction of robust immuneresponses and a favorable safety profile in multiple settings. for efficacy, immunogenicity and safety compared to a placebo.
“These data show consistent, high levels of efficacy and reaffirm the ability of the vaccine to prevent COVID-19 amid ongoing genetic evolution of the virus. Variant Virus Strains. It was generally well-tolerated and elicited robust antibody response in Phase 1/2 clinical testing. against the original virus strain, 86.3%
Many of the elderly patients who survived the virus were poor: not exactly the demographic you would expect to fare well in a health crisis. One of the most dangerous phenomena COVID-19 can trigger in your body is something called a cytokine storm, which is a potentially fatal amplification of an immuneresponse.
