This study described real-world treatment patterns and outcomes for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) in the USA. The study found that most patients received first-line treatment in accordance with clinical practice guidelines, but overall survival remained poor. The study highlights the need for novel therapies to improve patient survival.
Introduction Metastatic pancreatic ductal adenocarcinoma (mPDAC) is a common cancer with poor survival outcomes. Although treatment options are limited, real-world treatment patterns and outcomes are not well understood, particularly beyond first-line treatment. This study described real-world treatment patterns and outcomes for mPDAC in the USA. Methods This retrospective analysis used electronic health record-derived de-identified data of patients with mPDAC diagnosed between January 1, 2014 and June 30, 2021. Treatments were classified into six groups: (1) standard combination chemotherapy; (2) nonstandard combination chemotherapy; (3) single-agent chemotherapy; (4) targeted therapy; (5) clinical study drugs; and (6) off-label therapies. Analyses were descriptive in nature. Treatment utilization and switching, and time on treatment and time to discontinuation, were described by first-line (1LOT) and second-line (2LOT) treatment groups. Median overall survival (mOS) from 1LOT and 2LOT was stratified by treatment group, and for 1LOT on the basis of whether patients received further treatment. Results 1LOT included 6979 patients, 3241 (46%) of whom received further 2LOT. Standard combination chemotherapy was the most common 1LOT (70%) and 2LOT (46%). Nonstandard combination chemotherapy was used more as 2LOT (35%) than 1LOT (11%). First-line time on treatment was generally higher than second-line time on treatment, and time to discontinuation was lower than time on treatment. mOS in days (months) from 1LOT was 271 (8.9), 252 (8.3), 219 (7.2), 170 (5.6), 280 (9.2), and 182 (6.0), and mOS from 2LOT was 202 (6.6), 193 (6.3), 186 (6.1), 193 (6.3), 179 (5.9), and 97 (3.2), for groups 1-6, respectively. Within group 1, mOS from 1LOT was 318 days (10.4 months) for FOLFIRINOX and 241 days (7.9 months) for gemcitabine and nab-paclitaxel. Conclusion Most patients with mPDAC received 1LOT in line with clinical practice guidelines, yet mOS remains poor. This study highlights the need for novel therapies to demonstrate improved patient survival compared with therapies in current clinical practice guidelines.
