The PLATINUM Trial: Optimizing Chemotherapy for the Second-Line Treatment of Metastatic BRCA1/2 or PALB2-Associated Metastatic Pancreatic Cancer

Inclusion Criteria: * Metastatic pancreatic adenocarcinoma. Adenosquamous carcinoma, squamous carcinoma, acinar cell carcinoma, and carcinoma not otherwise specified are also acceptable * BRCA1/2 or PALB2 mutation (somatic or germline) identified on any Clinical Laboratory Improvement Amendments (CLIA)-certified gene panel. Mutations must be considered pathogenic or likely pathogenic by a reference database such as ClinVar or OncoKb.org. (Submission of mutation report will be required) * Measurable disease * Potential trial participants should have recovered from clinically significant adverse events of their most recent therapy/intervention prior to enrollment * Clinical or radiographic progression on first-line FOLFIRINOX (or nanoliposomal irinotecan, fluorouracil, leucovorin, and oxaliplatin \[NALIRIFOX\]) for metastatic disease * Patients whose front-line chemotherapy was required to be simplified due to toxicity associated with any of the constituent components of FOLFIRINOX/NALIRIFOX (e.g. simplified to leucovorin calcium, fluorouracil, and oxaliplatin \[FOLFOX\], leucovorin calcium, fluorouracil, and irinotecan \[FOLFIRI\], fluorouracil \[5-FU\] \[including capecitabine\]) will be eligible * Patients with progressive disease while on maintenance PARP inhibitor treatment after FOLFIRINOX (or NALIRIFOX), irrespective of how long ago they received FOLFIRINOX/NALIRIFOX, will also be eligible * Patients who develop metastatic disease during or within 6 months after …
