Purpose
Fluoropyrimidines and oxaliplatin have demonstrated some efficacy against pancreatic adenocarcinoma, but survival remains brief. Sorafenib is an oral multikinase inhibitor which we sought to combine with a unique capecitabine and oxaliplatin regimen for pancreatic adenocarcinoma.
Methods
We performed a multicenter phase II study of sorafenib 200 mg orally twice daily along with oxaliplatin 85 mg/m2 IV on days 1 and 15, followed by capecitabine 2250 mg/m2 orally every 8 h for six doses starting on days 1 and 15 of a 28-day cycle in patients who had no more than one previous chemotherapy regimen for their pancreatic adenocarcinoma. The primary objective was response rate; secondary objectives were progression-free survival (PFS), overall survival (OS), and safety.
Results
Twenty-four patients were enrolled; median age was 63 years (range 48–83). The most common related toxicities were fatigue, neuropathy, anemia, thrombocytopenia, diarrhea, nausea, leukopenia, and hand-foot syndrome. Grade 3 hand-foot syndrome was rare (4 %). Other grade 4 toxicities included abdominal pain (8 %), pulmonary embolism (4 %), and anemia (4 %). Three partial responses were seen (13 %), and 11 patients had stable disease (46 %) as their best response. Median PFS was 6.0 months (range 1.5–13 months). Median OS was 8.1 months (range 1.5–13.6 months).
Conclusions
Sorafenib, oxaliplatin, and capecitabine produced partial responses in patients with advanced pancreatic cancer including previously treated patients and demonstrated a PFS of 6 months with few grade 3/4 toxicities.
