Long-term results from the nITRO trial confirm the activity of perioperative NALIRIFOX in resectable PDAC. Inflammatory, genomic, and pharmacogenomic biomarkers strongly influenced treatment response, surgical eligibility, survival, and toxicity. Biomarker integration could enable more precise patient stratification and guide personalized perioperative strategies in PDAC.
To evaluate the effect of UGT1A1*28 homozygosity on the safety profile of NALIRIFOX (liposomal irinotecan + 5-fluorouracil/leucovorin + oxaliplatin) in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) in NAPOLI 3 (NCT04083235). This pre-specified exploratory analysis evaluated safety outcomes by UGT1A1*28 status in patients with mPDAC receiving NALIRIFOX or gemcitabine plus nab-paclitaxel in NAPOLI 3...These findings support the use of full NALIRIFOX dosing irrespective of UGT1A1*28 status. www.clinicaltrials.gov identifier is NCT04083235; EudraCT 2018-003585-14.

UGT1A1 (UDP glucuronosyltransferase family 1 member A1)
Given the lack of pronounced polarization effects with either monotherapy alone, these findings suggest that PDT, when combined with nal-IRI, induces antitumor and antimetastatic responses by remodeling innate immunity, even in the absence of adaptive T-cell activity. It also supports macrophage polarization as a key mechanism underlying PDT-nal-IRI combination therapeutic increase both in local and distant tumor burden.
The duration of previous chemotherapy, treatment line, and the CAR are useful predictors of PFS in patients with urPC receiving NFF. The proposed nomogram and risk stratification system may facilitate individualized treatment planning and support clinical decision-making.
