Her2 Breast Cancer

e13024 Background: Hertraz, the first trastuzumab biosimilar was approved in Morocco in 2017. Real world data on trastuzumab biosimilars are very limited or not available. HERLife is a prospective, non-interventional phase IV study program that investigated the experience of using Hertraz, a biosimilar for trastuzumab (Herceptin), under routine clinical practice conditions in Morocco. The primary aim of this study was to confirm the acceptable safety and tolerability of Hertraz. Methods: Ninety-nine patients with HER2-positive breast cancer treated with Hertraz were enrolled from 8 public and private sector hospitals and followed up for 12 months as part of this non-interventional study. Cardiac events (LVEF) and other unexpected or serious adverse events were monitored. The study arms consisted of patients with early breast cancer (Arm 1, n=70) and metastatic breast cancer (Arm 2, n=29) whose median age was 53 years in both groups. Results: Switching from Herceptin to Hertraz was observed in 45% of 29 MBC patients and 27% of 70 EBC patients. Switching was done at a median of 4th cycle. Pertuzumab was used in combination with Hertraz in 69% and 19% of patients in the metastatic and neoadjuvant settings, respectively. Two patients had a decline in LVEF. One patient treated with Hertraz alone and one patient treated with Hertraz and pertuzumab developed a decrease in LVEF requiring a three-week treatment discontinuation of Hertraz. Treatment of Hertraz was continued after 1 skipped cycle without occurrence of new side effects. No other trastuzumab related adverse events was observed. Four patients in the metastatic group and 2 patients in the early breast cancer arm had a relapse in the 12 months of clinical follow-up. Conclusions: The management of HER2+ breast cancer in Morocco follows the international recommendations. This is the first real world safety data of Hertraz from Morocco. The 12-month follow-up treatment with Hertraz showed an acceptable cardiac safety profile. In cases where there was a switch from Herceptin to Hertraz or Hertraz combined with pertuzumab, the safety profile was similar to that previously reported in other studies.

Abstract Background Multigene assays are being used increasingly to aid in decision-making about chemotherapy in breast cancer. Here, we present the 21-gene recurrence score (RS) of patients tested in routine clinical practice in Germany. Patients and Methods In a retrospective analysis, 4695 patients with hormone receptor-positive and HER2-negative early breast cancer (pT1 – 3, pN0 – 1, M0) were included in whom RS testing was conducted in Germany between November 2015 and July 2018. RS groups as defined in the TAILORx trial (RS result 0 – 10; 11 – 25; 26 – 100) were used. Results Of these patients, 21% were assigned to the low RS group, 63% to the midrange RS group, and 15% to the high RS group. 1772 (81%) of 2175 node-negative patients over 50 years of age were grouped either into the low RS group or the midrange RS group. The portion of patients with a low or midrange RS was 90% among node-positive patients (1284 of 1432 patients), 79% among patients with Ki-67-high (≥ 20%) tumors (1829 of 2310 patients), 86% vs. 70% among patients with G2 and G3 tumors (3244 of 3762 patients and 368 of 522 patients), respectively, 88% among patients with a tumor size of > 5 cm (140 of 159 patients), and 82% among node-negative patients at high clinical risk (1110 of 1352). Conclusions The distribution of the 21-gene RS in German patients that were tested in routine clinical practice indicates that, according to the results of the TAILORx trial, chemotherapy may not be beneficial in most of these.
