Dynamic PD-L1 Regulation Shapes Tumor Immune Escape and Response to Immunotherapy.
(PubMed, Cancers (Basel))
- "To investigate this, we adapted an ordinary differential equation model of combination therapy, incorporating the dynamics of the immune checkpoint inhibitor Avelumab and the immunostimulant NHS-muIL12. This work provides a validated mechanistic framework for adaptive resistance in combination immunotherapy. Quantified parameter differences between responder and non-responder phenotypes enable clearer biological interpretation and support the development of predictive tools for optimizing treatment strategies."

Dynamic PD-L1 Regulation Shapes Tumor Immune Escape and Response to Immunotherapy.
(PubMed, bioRxiv)
- "To investigate this, we adapted an ordinary differential equation model of combination therapy, incorporating the dynamics of the immune checkpoint inhibitor Avelumab and the immunostimulant NHS-muIL12. Incorporating therapy-dependent, dynamically regulated PD-L1 expression enabled a biologically grounded mechanism to reproduce experimental observations, leading us to formulate PD-L1 tumor expression as a dynamic variable ( ϵ ) and providing a mechanistic basis for both therapeutic synergy and treatment failure. Our results indicate that tumor resistance is linked to dose-dependent upregulation of PD-L1 following NHS-muIL12 treatment, explaining treatment failure, while PD-1/PD-L1 blockade in combination therapy enables effective anti-tumor immune responses."

Early changes in serum proteomic profiles predict anti-tumor activity in patients with advanced HPV-associated malignancies treated with novel combination immunotherapy
(SITC 2025)
- P1/2 | "Background We previously reported on the clinical activity of an HPV16 cancer vaccine (PDS0101), a tumor-targeting IL-12 immunocytokine (NHS-IL12, PDS01ADC), and a bifunctional agent targeting PD-L1 and TGF-β (bintrafusp alfa, BA) for the treatment of advanced HPV-associated malignancies, which demonstrated promising clinical activity (NCT04287868).1 Here, we perform a comprehensive survey of the peripheral immunome from patients treated with this novel immunotherapeutic combination to query systemic immunological changes and build models predicting clinical response.Methods Peripheral blood was serially collected from patients (n=50) for HPV16 circulating tumor DNA (ctDNA) detection, qualitative serum proteome profiling with the Olink ImmunoOncology platform, and immunophenotyping by flow cytometry. These data pave the way for outcome prediction in patients with HPV-associated malignancies using readily quantifiable molecular correlates from peripheral blood and..."
