PDO 2.0 tumor–immune response

TRiCBIO PDO 2.0 studies in clear-cell renal cell carcinoma (ccRCC) and non-small-cell lung cancer (NSCLC) combine tissue identity, immune baseline and treatment-response readouts to guide immuno-oncology study design.

STUDY AND RESULTS

From baseline context to immune response and treatment-related cell-death readouts

Tissue baseline, immune stimulation and treatment-response readouts offer complementary views for tumor–immune studies.

01Tissue and model context
Tissue and model context | PDO 2.0 TME study imageView image
Source tissue · PDO d7 · PDO d28 | PanCK · CD3 · DAPI

Compare tumor-epithelial and sample-associated immune signals

Source tissue and PDOs at days 7 and 28 show PanCK, CD3 and DAPI signals side by side for comparison of tumor-epithelial and sample-associated immune signals.

Provides baseline data for immune quantification and treatment studies
02Stimulation response
Stimulation response | PDO 2.0 TME study imageView image
±IL-2 | CD3 · PanCK · DAPI

Test the response to immune stimulation

Tissue imaging under ±IL-2 conditions shows the response to stimulation and can be combined with subsequent flow and cytokine assays.

Informs dose, time-point and cytokine-endpoint selection
03Treatment response

Connect immune-cell changes with cell-death readouts

PD-L1-, CD8- and CD56-associated flow profiles are interpreted alongside early-apoptosis and necrosis readouts to compare immune-associated and cell-death changes under ICB conditions.

NEXT PROGRAM DECISIONS

Plan candidate and dose comparisons and confirmation in independent samples

Use immune-cell profiles and treatment responses to design the next candidate, dose and independent-sample study.

HOW THE STUDY IS BUILT

Compare immune and cell-death changes across treatment conditions

Sample baseline informs the culture window, flow-cytometry gating and replication design so immune and cell-death-related changes can be compared clearly across treatment conditions.

INTERPRETATION

Use TME readouts to refine treatment studies

How the results are used

Select histology, cell-death and T-cell profiling endpoints for immunotherapy studies across different sample contexts.

Study application

Programs select the observation window and assay panel from each sample's immune baseline and culture state, then extend the study through replication and additional samples.

Follow-on study

Set dose, time, cytokine and flow analyses around the candidate mechanism, then compare responses across replicates and independent samples.
