Safety and tolerability of subcutaneous trastuzumab for the adjuvant treatment of human epidermal growth factor receptor 2-positive early breast cancer: SafeHer phase III study's primary analysis of 2573 patients

Aim To assess the safety and tolerability of adjuvant subcutaneous trastuzumab (Herceptin® SC, H SC), delivered from an H SC Vial via hand-held syringe (Cohort A) or single-use injection device (Cohort B), with or without chemotherapy, for human epidermal growth factor receptor 2 (HER2)-positive stage I to IIIC early breast cancer (EBC) in the phase III SafeHer study (NCT01566721). Methods Patients received 600 mg fixed-dose H SC every 3 weeks for 18 cycles. The chemotherapy partner was at the investigators' discretion (H SC monotherapy was limited to ≤10% of the population). Data from the first H SC dose until 28 days (plus a 5-day window) after the last dose are presented. Results are descriptive. Results In the overall population, 2282/2573 patients (88.7%) experienced adverse events (AEs). Of the above, 128 (5.0%) patients experienced AEs leading to study drug discontinuation; 596 (23.2%) experienced grade ≥ 3 AEs and 326 (12.7%) experienced serious AEs. Grade ≥ 3 cardiac disorders were reported in 24 patients (0.9%), including congestive heart failure in eight (0.3%). As expected, the AE rates varied according to the timing of chemotherapy in both cohorts, with higher rates in concurrent versus sequential chemotherapy subgroups. In the concurrent chemotherapy subgroup, AEs were more common during the actual period of concurrent chemotherapy compared with the period when patients did not receive concurrent chemotherapy. Conclusion SafeHer confirms the safety and tolerability of the H SC 600 mg fixed dose for 1 year (every 3 weeks for 18 cycles) as adjuvant therapy with concurrent or sequential chemotherapy for HER2-positive EBC. These primary analysis results are consistent with the known safety profile for intravenous H and H SC

Overweight is associated to a better prognosis in metastatic colorectal cancer: A pooled analysis of FFCD trials

IF 7.191 (2017)International audienceBACKGROUND:Previous studies showed that high and low body mass index (BMI) was associated with worse prognosis in early-stage colorectal cancer (CRC), and low BMI was associated with worse prognosis in metastatic CRC (mCRC). We aimed to assess efficacy outcomes according to BMI.PATIENTS AND METHODS:A pooled analysis of individual data from 2085 patients enrolled in eight FFCD first-line mCRC trials from 1991 to 2013 was performed. Comparisons were made according to the BMI cut-off: Obese (BMI ≥30), overweight patients (BMI ≥ 25), normal BMI patients (BMI: 18.5-24) and thin patients (BMI <18.5). Interaction tests were performed between BMI effect and sex, age and the addition of antiangiogenics to chemotherapy.RESULTS:The rate of BMI ≥25 patients was 41.5%, ranging from 37.6% (1991-1999 period) to 41.5% (2000-2006 period) and 44.8% (2007-2013 period). Comparison of overweight patients versus normal BMI range patients revealed a significant improvement of median overall survival (OS) (18.5 versus 16.3 months, HR = 0.88 [0.80-0.98] p = 0.02) and objective response rate (ORR) (42% versus 36% OR = 1.23 [1.01-1.50] p = 0.04) but a comparable median progression-free survival (PFS) (7.8 versus 7.2 months, HR = 0.96 [0.87-1.05] p = 0.35). Subgroup analyses revealed that overweight was significantly associated with better OS in men. OS and PFS were significantly shorter in thin patients.CONCLUSION:Overweight patients had a prolonged OS compared with normal weight patients with mCRC. The association of overweight with better OS was only observed in men. The pejorative prognosis of BMI <18.5 was confirmed.Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserve
