Details and patient eligibility

About

The primary objective of this study was to determine the progression free survival in patients with metastatic pancreatic cancer and in patients with locally advanced unresectable non-metastatic pancreatic cancer treated with a dose-attenuated modification of folinic acid, fluorouracil, irinotecan, and oxaliplatin (FOLFIRINOX). Secondary endpoints included: determine objective response rate according to RECIST; determine overall survival; evaluate toxicity; determine rate of resection in locally advanced unresectable stratum; correlate time to progression, objective response, and overall survival with early changes in glucose metabolism using [18F]-fluorodeoxyglucose (FDG)-positron emission tomography (PET) scanning.

Full description

A phase II open label single arm multi-institutional study at Yale's Smilow Cancer Hospital (New Haven, CT, USA), the Smilow Cancer Hospital Care Centers (regional community-based clinics), the VA Connecticut Healthcare System West Haven Campus (West Haven, CT, USA) and Bridgeport Hospital (Bridgeport, CT, USA). The primary objective of this study was to determine the PFS in patients with MPC and LAPC treated with a dose attenuated modification of FOLFIRINOX.

NOTE: Upon results reporting (2016), the registration record was reorganized to display MPC and LAPC groups in individual arms. The most meaningful comparison is between MPC/LAPC and historical controls. That is how results are reported in the published paper, see citations.

75 participants in 2 patient groups

MPC modified FOLFIRINOX

Experimental group

Description:

Patients with metastatic pancreatic cancer (MPC) were treated with modified FOLFIRINOX every 2 weeks as follows: oxaliplatin 85 mg m 2 infused over 120 min, immediately followed by folinic acid 400 mg m 2 infused over 120 min with the addition, after 30 min, of irinotecan 135 mg m 2 infused over 90 min, followed by 5FU 300 mg m 2 IV bolus, followed by 2400 mg m 2 continuous infusion for 46 h (25% reduction in bolus 5FU and irinotecan doses). All patients received pegylated filgrastim with each cycle on day 3 or 4 in the absence of severe leukocytosis. All patients routinely received palonosetron, aprepitant and dexamethasone for emesis prophylaxis.

Treatment:

Drug: Folfirinox

LAPC modified FOLFIRINOX

Experimental group

Description:

Patients with locally advanced pancreatic cancer (LAPC) were treated with modified FOLFIRINOX every 2 weeks as follows: oxaliplatin 85 mg m 2 infused over 120 min, immediately followed by folinic acid 400 mg m 2 infused over 120 min with the addition, after 30 min, of irinotecan 135 mg m 2 infused over 90 min, followed by 5FU 300 mg m 2 IV bolus, followed by 2400 mg m 2 continuous infusion for 46 h (25% reduction in bolus 5FU and irinotecan doses). All patients received pegylated filgrastim with each cycle on day 3 or 4 in the absence of severe leukocytosis. All patients routinely received palonosetron, aprepitant and dexamethasone for emesis prophylaxis.
