Background: The objective of ECOG 1503 was to determine the response rate of this combination in the second-line treatment of advanced NSCLC. Methods: Triapine 105 mg/m2 IV on days 1, 8, and 15, and gemcitabine 1,000 mg/m2 on days 1, 8, and 15, of a 28 day cycle. Results: Eighteen patients enrolled. Three patients were not eligible due to protocol violations. No objective antitumor responses were seen. Three patients (20%) experienced stable disease (90% CI 5.7-44%). Median overall survival: 5.4 months (95% CI 4.2-11.6 months); median time to progression: 1.8 months (95% CI 1.7-3.5 months). Five patients developed acute infusion reactions to Triapine® related to elevated methemoglobinemia. Patients with MDR1 variant genotypes of C3435T experienced superior overall survival compared to non-variants (13.3 vs. 4.3 months, respectively, p = 0.023). Conclusion: This regimen did not demonstrate activity in relapsed NSCLC. Prolonged survival seen with MDR1 variant genotypes is hypothesis-generating. © 2009 Springer Science+Business Media, LLC.

Cancer Chemotherapy and Pharmacology

Abstract 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. © 2015 Springer-Verlag Berlin Heidelberg.

Clinical Breast Cancer

Background Irinotecan has a 20% to 25% response rate (RR) in patients with previously treated metastatic breast cancer (MBC). Epidermal growth factor receptor (EGFR) is overexpressed in some MBC, especially in triple-negative breast cancer (TNBC). Cetuximab is a monoclonal antibody against EGFR with additive preclinical activity with irinotecan. Patients and Methods We report a 1-stage phase II study on MBC, measurable disease, and previous anthracycline and/or taxane therapy. Patients received cetuximab 400 mg/m2 on day 1 cycle 1 then 250 mg/m2 weekly thereafter and irinotecan 80 mg/m2 on days 1 and 8 of each 21-day cycle. The primary end point was overall RR (ORR) according to Response Evaluation Criteria in Solid Tumors criteria (version 1.1). Results Of 19 eligible patients enrolled from February to September 2006, 14 patients (74%) had visceral disease, seven patients (37%) were hormone receptor-positive, two patients (11%) HER2-positive, and 11 patients (58%) were triple-negative. Patients received a median of 2 cycles (range, 1-37). Confirmed ORR was 11% (95% confidence interval [CI], 1%-33%), with 1 partial response and 1 complete response. One patient had stable disease for 8 months. RR for TNBC versus non-TNBC was 18% versus 0% (P =.49). Median time to progression was 1.4 months (95% CI, 1.0-2.2) and median overall survival was 9.4 months (95% CI, 2.8-16.1). Twelve patients had disease progression within 2 cycles during therapy. Because of a low RR and rapid disease progression, the study leadership decided to close the trial early. Conclusion The tolerability of the combination of cetuximab and irinotecan is acceptable but demonstrated low overall activity. Potentially promising results were noted in patients with TNBC and further studies of these patients might be considered. © 2016 Elsevier Inc. All rights reserved. Source

BACKGROUND: Obesity has been associated with inferior outcomes in operable breast cancer, but the relation between body mass index (BMI) and outcomes by breast cancer subtype has not been previously evaluated. METHODS: The authors evaluated the relation between BMI and outcomes in 3 adjuvant trials coordinated by the Eastern Cooperative Oncology Group that included chemotherapy regimens with doxorubicin and cyclophosphamide, including E1199, E5188, and E3189. Results are expressed as hazard ratios (HRs) from Cox proportional hazards models (HR >1 indicates a worse outcome). All P values are 2-sided. RESULTS: When evaluated as a continuous variable in trial E1199, increasing BMI within the obese (BMI, ≥30 kg/m2) and overweight (BMI, 25-29.9 kg/m 2) ranges was associated with inferior outcomes in hormone receptor-positive, human epidermal growth receptor 2 (HER-2)/neu-negative disease for disease-free survival (DFS; P =.0006) and overall survival (OS; P =.0007), but not in HER-2/neu-overexpressing or triple-negative disease. When evaluated as a categorical variable, obesity was associated with inferior DFS (HR, 1.24; 95% confidence interval [CI], 1.06-1.46; P =.0008) and OS (HR, 1.37; 95% CI, 1.13-1.67; P =.002) in hormone receptor-positive disease, but not other subtypes. In a model including obesity, disease subtype, and their interaction, the interaction term was significant for OS (P =.02) and showed a strong trend for DFS (P =.07). Similar results were found in 2 other trials (E5188, E3189). CONCLUSIONS: In a clinical trial population that excluded patients with significant comorbidities, obesity was associated with inferior outcomes specifically in patients with hormone receptor-positive operable breast cancer treated with standard chemohormonal therapy. © 2012 American Cancer Society.

Summary: Chemotherapy has yielded minimal clinical benefit in pancreatic and biliary tract cancer. A high-dose, short course capecitabine schedule with oxaliplatin, has shown some efficacy with a lower incidence of palmar-plantar erythrodysesthesia. Achieving high exposures of the targeted agent sorafenib may be possible with this shorter schedule of capecitabine by avoiding dermatologic toxicity. All patients had pancreatic or biliary tract cancer. Patients in both cohorts received oxaliplatin 85 mg/m2 followed by capecitabine 2,250 mg/m2 PO every 8 h x 6 doses starting on days 1 and 15 of a 28 day cycle, or 2DOC (2 Day Oxaliplatin/Capecitabine). Cohort 1 used sorafenib 200 mg BID, and cohort 2 used sorafenib 400 mg BID. Sixteen patients were enrolled. Across all cycles the most common grade 1 or 2 adverse events were fatigue (10 pts), diarrhea (10 pts), nausea (9 pts), vomiting (8 pts), sensory neuropathy (8 pts), thrombocytopenia (7 pts), neutropenia (5 pts), and hand-foot syndrome (5 pts). Grade 3 toxicites included neutropenia, mucositis, fatigue, vomiting and diarrhea. Cohort 1 represented the MTD. Two partial responses were seen, one each in pancreatic and biliary tract cancers. The recommended phase II dose of sorafenib in combination with 2DOC is 200 mg BID. There were infrequent grade 3 toxicities, most evident with sorafenib at 400 mg BID. © 2012 Springer Science+Business Media New York. Source
