It wasn’t a silver bullet to the hard problem of drugdevelopment, but it wasn’t too far off either. Unlike what many predicted, the rise of computation as a dominant force in drugdevelopment did not kill “Big Pharma.” A flurry of new, promising therapeutic targets arose.
The drugs work by blocking a protein, PD-1 — which helps keep immuneresponses in check — and stimulating the immune system to attack tumors. We wanted to see whether there were as yet undiscovered drug targets that would lead to amazing cancer immunotherapies,” Manguso said.
These peptides are a vital part of the immune system’s display-recognition mechanism that enables T cells to distinguish between self and non-self-antigens, recognizing intruders to initiate immuneresponses.
To be therapeutically useful, antigenic peptides must be presented in a way that allows immuneresponses to destroy cancer cells without causing unacceptable damage to healthy tissue. With convergent technology, it is possible to engineer monoclonal antibodies that mimic the specificity of TCRs for tumour‑specific pHLA targets.
As an undergraduate biology student, I spent some time in a TB lab working on antibiotic resistance — a growing concern for drugdevelopers. Testing the engineered cells against four common drugs, I found that the M. tuberculosis. A Peace Corps Volunteer administers the BCG vaccine to a six-year-old Korean boy.
The NIH continues to support the development of some very innovative therapies to control SARS-CoV-2, the coronavirus that causes COVID-19. They found in mouse models of severe COVID-19 that intravenous infusion of an engineered ACE2 decoy prevented lung damage and death. How’s that?
Such contaminants could have the same toxic effects as the bacterial infection, or provoke a severe immuneresponse in the patient, and therefore the phage mixtures must go through extensive purification and testing procedures. Locus has products in development targeting four common sources of bacterial infections: E.
Xiaomin Fan, Founder, President and CEO of AvantGen, “Even with the recent Emergency Use Authorization of multiple vaccines, we believe there remains an urgent need for potent antibody therapies and prophylactics for immunocompromised patients who cannot mount an adequate immuneresponse either to the vaccine or to subsequent viral infection.
Engineering sites on the antibody to enable specific and consistent attachment of the cytotoxic drug to achieve an optimal drug-to-antibody ratio (DAR). The development of more hydrophilic linkers helps maintain the structural and functional integrity of the antibody in the final conjugate. 2024;347:122676. BMC Cancer.
The pharmaceutical industry grapples with the persistent challenge of high attrition rates and escalating costs inherent in drugdevelopment. This necessitates exploring alternative strategies to expedite drug discovery and optimize resource allocation.
2,3 Engineering both the capsid and DNA cargo improves the safety and efficacy of rAAV vectors and expands their clinical applications. Therefore, vectors based on these serotypes may enable targeted gene delivery and optimal transduction efficiency.
Advances in genetic engineering have enabled researchers to enhance bacteriophage efficacy and overcome bacterial resistance mechanisms. Developing Antimicrobial Peptides and Biomolecules In addition to traditional small-molecule antibiotics, researchers are exploring the potential of antimicrobial peptides (AMPs) and other biomolecules.
Chimeric PD-1 T-cells also release cytokines to further initiate immuneresponses to eradicate the tumor cells. The pipeline development is leveraged through the Company’s proprietary target discovery engine called “DIAMOND.” The Company maintains offices in Houston, Texas.
In addition, the observed median PFS shows that the regimen can induce a sustained and durable response, which is also shown consistently by the induction of a specific immuneresponse. Commenting on this novel immunotherapy regimen, Prof. Christophe Le Tourneau, M.D., About TG4001. Transgene has an ongoing Invir.IO
Both vaccine candidates incorporate Novavax’ proprietary saponin-based Matrix-M adjuvant in order to enhance the immuneresponse and stimulate high levels of neutralizing antibodies.
In drugdevelopment, biochemical assays might be used to determine a product’s binding affinity to a target receptor of interest, along with the strength, stability and duration of the target-ligand complex after the product binds to the receptor. The new draft guidance can be broken into three main parts.
Both vaccine candidates incorporate Novavax’ proprietary saponin-based Matrix-M adjuvant in order to enhance the immuneresponse and stimulate high levels of neutralizing antibodies.
Unlocking this potential requires a dual approach: Identifying suitable targets within tumours and developing effective biomarkers for patient stratification. Discovering and optimising potent therapeutics that direct the immuneresponse against these targets. Nature Reviews Drug Discovery. 2023 Oct 27;22(12):9961017.
This is primarily due to the inability of the engineered CAR-T cells to persist long enough to maintain remission. IL-15 is a cytokine that plays a key role in the activation, survival and proliferation of key immune cells such as CD8+ T cells and natural killer (NK) cells. This is where NKTR-255 comes into play.
In January 2020 four papers were published that described the correlation between the presence of tertiary lymphoid organs and B cells with successful immune checkpoint therapy in diverse cancer indications (see here ). I particularly like the idea of engineering CD47 antagonism into other modalities, eg. Fc-hacking immuneresponses.
