What is mRNA?Nucleic acid medicine for temporary expression of a target protein in the bodyThe goal is therapeutic effect by producing necessary proteins within cells. While widely known for its application in infectious disease vaccines, it is also expected to be utilized in a wide range of fields in recent years, such as protein replacement therapy and cancer immunotherapy. Advances in delivery technologies, including lipid nanoparticles (LNPs), have made it possible to efficiently deliver mRNA to target cells, and the practical application of various mRNA drugs is progressing.
Comirnaty (BNT162b2) is,COVID-19 mRNA vaccines that deliver mRNA into the body using lipid nanoparticles (LNPs)This is a prime example that has greatly advanced the practical application of mRNA therapeutics in the field of infectious diseases, and the research and development of mRNA therapeutics for various diseases is accelerating globally based on this practical application.
Spikevax (mRNA-1273) isCOVID-19 mRNA vaccine combining LNP (lipid nanoparticles) and mRNAThis is an example of a practical application of the mRNA platform, and it became an important achievement that broadened the possibilities of mRNA medicine applications not only for infectious disease prevention but also for various diseases.
Personalized cancer vaccines areTherapeutic method using mRNA encoding patient-specific cancer neoantigensIt is being developed. It is currently a prime example of a clinical trial and development stage, and as an approach that aims for personalized treatment for each patient, it is expected to be a promising technology that shows the future direction of mRNA drug discovery.
mRNA is difficult to be incorporated into cells on its own and is easily degraded in the body.Therefore,Delivery technology greatly impacts drug efficacy.LNP (lipid nanoparticle) and other DDS (drug delivery systems) are crucial foundational technologies for mRNA drug development, as they efficiently deliver mRNA to target tissues while protecting it.
In mRNA therapeutics,Ensure sufficient expression efficiency and durationThis directly leads to drug efficacy. Therefore, in addition to optimizing mRNA stability and translation efficiency, important development challenges include exploring biomarkers that consider patient variability and evaluating protein expression in vivo.
In mRNA therapeutics,Appropriately evaluate cytokine induction and inflammatory responses due to innate immune activationThis is required. In safety evaluations, it is expected that immune responses will be predicted using pathological models with high human extrapolation, allowing for a more accurate assessment of safety and efficacy from the preclinical stage to clinical trials.
Delivery assessment to the target organization isTo confirm if mRNA and LNPs are properly delivered to the target tissue.It is performed to understand the overall efficiency of delivery and pharmacokinetics by combining PK and LNP evaluations, in addition to in vivo distribution within the organization and distribution of nucleic acid drugs, and to evaluate their relationship with efficacy.
In protein expression and efficacy evaluation,Comprehensively confirming target engagement, protein expression levels, and duration of expression.We will further evaluate the effectiveness more appropriately by combining biomarker analysis and pharmacological studies to assess the relationship between target action and efficacy from multiple perspectives.
In disease models with high human translatability,Evaluate using a combination of organoids, iPS cells, humanized mice, and patient-derived models.We will leverage the characteristics of each model to predict drug efficacy and safety in humans more realistically, thereby improving the reliability of non-clinical evaluations.
In mRNA therapeutics,Comprehensive evaluation of specific safety, including immunostimulation and LNP-derived toxicity.We will also confirm long-term safety in addition to the presence or absence of cytokine storms and hepatotoxicity, and by combining multiple safety tests, we will gain a multifaceted understanding of the risks and enhance their translatability to clinical practice.
mRNA is a drug discovery modality that holds promise for treating a wide range of diseases, including infectious diseases, cancer, and rare diseases, in addition to vaccines. However, challenges such as delivery, safety, and human extrapolation remain, making appropriate non-clinical evaluation essential. To advance development efficiently, selecting a CRO that understands the characteristics of mRNA therapeutics and can propose an evaluation strategy is key to success.
In drug discovery, the quality and efficiency of non-clinical studies have a direct impact on clinical success rates, development costs, and overall length of time required in R&D.
In recent years, there has been more demand for clinically relevant data, globally accepted reliability, and accurate early-stage screening.
Thus, it is more important than ever to select the right CRO (Contract Research Organization) for strategic approach.
In this article, we highlight three CROs with proven technical capabilities, expertise, and long standing track records. These are our TOP 3 choices based on their capabilities and the specific target goals of the researchers for their non-clinical studies.
