5Research Pillars

Research Programs

Five interconnected pillars driving translational breakthroughs in pancreatic ductal adenocarcinoma (PDAC).

POLQ & Synthetic Lethality

We study polymerase theta (POLQ) and error-prone end-joining pathways to uncover synthetic lethal interactions exploitable in HRD-deficient tumors, complementing PARP inhibitor strategies.

Neoantigens & Biologics

We develop pipelines for neoantigen discovery and biologic modalities targeting tumor-specific epitopes. Our translational analyses from the POLAR trial showed that frameshift indel neoantigens are associated with durable clinical benefit in HRD tumors.

High-throughput Screening

We deploy genetic and small-molecule screens — including CRISPR-based functional genomics — to identify combination strategies, resistance mechanisms, and novel therapeutic targets in PDAC.

Setidegrasib in Advanced Non–Small-Cell Lung Cancer and Pancreatic Cancer

Park W, Kasi A, Spira AI, Paz-Ares Rodríguez L, Herzberg BO, Pelster MS, et al.

First-in-human phase 1 study of setidegrasib (ASP3082), a first-in-class KRAS G12D targeted protein degrader. Among 21 patients with metastatic PDAC receiving the 600 mg dose, 24% achieved objective response. In NSCLC (n=45), ORR was 36% with median PFS of 8.3 months.

Pembrolizumab and Olaparib in HRD Metastatic Pancreatic Cancer: The POLAR Trial

Park W (Corresponding Author), O’Reilly E, et al.

Phase 2 POLAR trial evaluating maintenance pembrolizumab + olaparib in biomarker-stratified metastatic PC. In cohort A (BRCA1/2, PALB2; n=33): median PFS 8.3 months, median OS 28 months, 3-year OS rate 44%. ctDNA response and enrichment of frameshift indel neoantigens were associated with durable clinical benefit.
