Patient-Derived Organoids (PDOs) for Oncology Drug Evaluation

By integrating immune cells from the tumor microenvironment, we enable more accurate assessment of oncology drugs and immunotherapies – bringing your research closer to predictive, patient-relevant outcomes.

What Are Patient-Derived Organoids?

Patient-derived organoids (PDOs) are 3D cell cultures grown directly from a patient’s tumor tissue. Because they are cultured from tumor biopsies, PDOs preserve the tumor’s genetic fidelity and phenotypic traits better than 2D cell lines. This makes patient-derived tumor organoids a more clinically relevant model for predicting drug efficacy and patient response, while reducing reliance on animal models.

with Patient-Derived Organoids (PDOs)

High-Fidelity Preclinical Models

Cultured directly from tumor biopsies, our PDOs ensure the ideal preservation the tumor’s genetic fidelity and phenotypic traits. Bypassing the limitations of 2D cell lines or animal models, Lambda’s PDOs provide highly clinically relevant platforms, enabling more accurate prediction of drug efficacy and patient response.

Extensive Organoid Biobanking

Our expansive biobank spans multiple cancer types, offering a diverse library of organoids that supports robust drug screening and discovery. This resource accelerates decision-making across the R&D pipeline and helps identify promising candidates for a variety of tumor profiles.

Fully customized research services

Our platform offers a fully customizable suite of organoid-based preclinical research services designed to meet your unique needs. This includes integrating donor-matched immune microenvironments, personalized PDOs lineups, and generating high-resolution functional data (HCS, scRNAseq, multi-plex IHC, and more).

How We Build and Validate Patient-Derived Organoids

  1. Tumor biopsy collection from our hospital and clinical networks, with patient consent and ethics approval.
  2. Organoid establishment and expansion.
  3. Characterization, confirming each line is still the patient’s tumor: key driver mutations retained versus the matched tissue (targeted cancer-panel sequencing), MSI status, standard diagnostic IHC panels, and seeding uniformity checked per well before every assay.
  4. Biobanking across multiple cancer types.
  5. Assay: drug screening, immune co-culture, high-content screening (HCS), scRNA-seq and multiplex readouts.

Applications of Patient-Derived Tumor Organoids

  • Anti-cancer drug screening and efficacy evaluation
  • Immunotherapy testing with donor-matched immune microenvironments (cytotoxic T cells, TILs, macrophages, CAFs)
  • Drug modalities: small molecules, antibodies, mRNA and cancer vaccines
  • Biomarker and resistance studies

Patient-Derived Organoids FAQ

What is a patient-derived organoid (PDO)?

A 3D culture grown from a patient’s tumor biopsy that preserves the original tumor’s genetic and phenotypic features, used to test how a tumor responds to drugs. Lambda Biologics cultures its PDOs directly from tumor biopsies.

How are patient-derived organoids different from cell lines?

PDOs keep the tumor’s heterogeneity and 3D structure, which 2D cell lines lose. This gives a more clinically relevant read-out of drug efficacy.

Which cancer types are in your PDO biobank?

Can you co-culture PDOs with immune cells?

Yes. Lambda Biologics integrates immune cells from the tumor microenvironment, including cytotoxic T cells, to evaluate immunotherapies.

What drug modalities can be tested on tumor organoids?

Small molecules, antibodies, mRNA and cancer vaccines, among the other modalities listed on this page.

How long does a PDO drug screening study take?

Typically 4–5 weeks, depending on the organoid’s differentiation and maturation time.
