Landmark Clinical Studies
PD-1/PD-L1 Interaction Predicts Survival in NSCLC
188 patients. High interaction: 31 months OS vs 10 months (P<0.0001). PD-L1 expression did NOT predict (P=0.162).
Combined CTLA-4/CD80 and PD-1/PD-L1 Checkpoint Biomarkers
"Double high" patients: 35 months OS. Neither biomarker predicted chemo response—ICI-specific.
PKB/Akt Activation Predicts Survival in ccRCC
Activation: HR=0.228, P=0.002. Expression: HR=1.390, P=0.548. Function predicts; expression does not.
Methodology & Validation
iFRET for PD-1/PD-L1 in Melanoma and NSCLC
Established two-site cell-cell amplified FRET methodology. High interaction correlates with anti-PD-1 response.
Checkpoint Interactions in RFA-Treated Lung Metastases
First CTLA-4/CD80 quantification at 1-10nm resolution. Interaction did NOT correlate with expression.
