Antagonist Development Service for Cancer Immunotherapy

Immuno-oncology Antagonist

Immunomodulators are a class of drugs that can regulate the function of the immune system, and are used for a series of immune-related diseases, such as autoimmune diseases, organ transplant rejection, etc., by suppressing or enhancing the activity of the immune system. Creative Biolabs offers a range of services related to immune antagonists, including synthesis and design, biomarker testing, in vitro and in vivo evaluation, and more to provide a solid theoretical basis for your cancer immunology research.

Our Service

A great deal of research and design is required before an immune antagonist can be synthesized. The approximate synthetic route of the immune antagonist is shown in the figure below:

Assessing and regulating pathway-related biomarkers may predict response to tumor immunotherapy. Creative Biolabs offers assays for the following immuno-related markers of oncology:

Method Objective
PD-L1 expression level, tumor mutational burden (TMB), microsatellite instability Screening for optimal immunotherapy outcomes
Expression profiling of inflammatory genes in dendritic cells or tumor-infiltrating lymphocytes and T cells To predict response to immunotherapy drugs
Correlation of peripheral blood with TME PD response To provide a suitable immunotherapy solution
Tumor RNA gene expression evaluation For immune activation and cytokine assessment
Tumor tissue DNA evaluation For the evaluation of TMB and tumor immunogenicity
Expression of tumor PD-L1 on tumors and immune cells For comparison at baseline and in treatment

Choosing the right animal model is critical for preclinical trials, and Creative Biolabs can offer several common models:

Type Advantage Disadvantage Application
isogenic mouse It can stably express luciferase groups and is easy to use. Tumors originate from mice and do not directly match human disease, so they are not a good predictor of clinical outcomes. Suitable for screening large numbers of drug candidates.
Transgenic/Genetically Engineered Mouse Models (GEMMs) The disease progresses more naturally. Mutations in transgenic models limit neoantigen production and are less suitable for immuno-oncology studies Study the function of specific genes and disease mechanisms.
Cell-derived xenograft model (CDX) In the construction of tumor cell lines, the tumorigenesis rate is high, the modeling time is short, the reproducibility is good, the cost is low, and fluorophores can be added. Tumors are cultured in vitro and lack a human-derived tumor growth environment. Immunodeficient mice need to be selected for construction, which is not fully suitable for studying the role of the immune system in tumor development. Conduct preclinical pharmacodynamics testing, PK/PD correlation and combination therapy studies.
Patient-derived xenograft model (PDX) Heterogeneous tumors that follow the effects of human primary tumor resistance and TEM on drugs, preserving the genetic characteristics of patients. Some models are difficult to build and grow at a slower rate than CDX. Targeted reagent R&D and production, personalized therapy R&D.
Humanized mouse/immune stand-in model Partial human immune system with human drug targets that allow the study of human cancer cell lines or primary patient-derived tumors in the context of autologous or xenoimmunology. The immune system is suboptimal, and human xenogeneic inhibitor versus host disease is common. To investigate the efficacy of murine homologous or alternative antibodies, as well as aspects of the human immune response in mouse models
Tumor organoids Similar to the original tumor, it is a more clinically relevant model for preclinical research. Lack of key components in TME. Drug screening and prediction of efficacy to a certain extent; Avoid medication side effects.
