2 Topics 1 GS3 05: Survival analysis of the prospectively randomized phase III GeparSepto trial GS3 04: A randomized phase III study of adjuvant trastuzumab for a duration of 9 weeks versus 1 year, combined with adjuvant taxane anthracycline chemotherapy, for early HER2 positive breast cancer (the SOLD study). Incidence and management of diarrhea with adjuvant Pertuzumab and Trastuzumab in HER2 positive breast cancer

3 Topics 2 Pharmacokinetic results of a subcutaneous injection of Trastuzumab into the thigh versus into the abdominal wall in patients with HER2 positive primary breast cancer (BC) treated within the neo /adjuvant GAIN 2 study Efficacy and safety of subcutaneous or intravenous Trastuzumab in patients with HER2 positive early breast cancer after 5 years treatment free follow up: Final analysis from the phase III, open label, randomized HannaH study A phase Ib dose finding study of subcutaneous Pertuzumab in combination with subcutaneous Trastuzumab in healthy male volunteers and female patients with early breast cancer

4 GS3 05: Survival analysis of the prospectively randomized phase III GeparSepto trial GeparSepto: Überträgt sich die signifikant höhere pcr Rate mit nab-pac in ein besseres DFS?

15 Fazit pcr Rate gesteigert mit nabpaclitaxel vs. lösl. Paclitaxel als Teil einer sequenziellen Anthracyclin/Taxan basierten Chemotherapie Höhere pcr Rate übersetzt sich in ein signifikant und klinisch relevant verbessertes rezidivfreies Überleben (HR=0.69, log rank p=0.0044) Auch Pat. mit Ki67 <20% bzw. non pcr profitieren bez. DFS von nab Paclitaxel Rate peripherer Neuropathien unter nabpaclitaxel nach Dosisreduktion gesenkt: Grad ¾: 150/ 125 (mg/m2 KOF) 15%/ 8% (nach 464 rekrutierten Pat.)

16 A randomized phase III study of adjuvant Trastuzumab for a duration of 9 weeks versus 1 year, combined with adjuvant Taxane Anthracycline chemotherapy, for early HER2 positive breast cancer The Synergism Or Long Duration (SOLD) trial Joensuu H et al.
