CDX Models for Cancer Therapy Development
Cell line derived xenograft models offer key decision-making information that allows the therapeutic candidates to move forward in preclinical testing for cancer immunotherapy development. To improve the cost-effectiveness and timeliness of sponsored preclinical development projects, Creative Biolabs has established multiple in vivo analysis systems with various CDX models to evaluate the candidates' mechanism of action, PD/PK profiles.

Highlights
Oncology Specialist Focus
Unlike generalist CROs, our entire scientific team is specialized in cancer biology, ensuring expert design and interpretation of your CDX data.
Deep Biobank & Coverage
We maintain an industry-leading biobank of CDX models, covering a diverse spectrum of solid tumors and hematological malignancies (including leukemias and lymphomas). This deep inventory ensures rapid access to your specific cancer subtype.
Advanced IC-CDX Platform
For I-O applications, our engineered immunocompetent models (IC-CDX) feature reconstituted human immune systems (HIS). This allows you to study complex human T-cell activation and checkpoint inhibitor efficacy using the highly reproducible CDX backbone.
Precision Implantation Expertise
We are highly proficient in technically demanding orthotopic implantations (e.g., intracranial, hepatic, pancreatic), which provide a more clinically relevant tumor microenvironment than standard subcutaneous models.

Customer Reviews
Reproducibility & Cost-Efficiency
Creative Biolabs' CDX models significantly improved the standardization and rapid throughput of our initial screening. The low variability facilitated the confident exclusion of non-viable candidates, thereby preserving budget for PDX validation. - Dr. J**n D***e.
Orthotopic Relevance
Creative Biolabs' expertise in orthotopic implantation was critical for our hepatic carcinoma study. It enhanced the translational relevance by accurately mimicking the native tumor environment, which was essential for evaluating our compound. - Dr. S**a R****u.
FAQs
Q: What is the comparative utility of CDX models versus PDX models in efficacy testing?
A: CDX models are superior for high-volume, mechanism-driven screening due to their reproducibility and cost-efficiency. PDX models are reserved for later validation, confirming clinical relevance using greater tumor heterogeneity.
Q: What constitutes the principal advantage of selecting a CDX model over an in vitro assay?
A: Our CDX models provide a crucial functional assessment in vivo, integrating the drug's pharmacokinetics and its ability to penetrate and inhibit tumor growth within a complex living system.
