Abstract 1744


Neoadjuvant–adjuvant subcutaneous trastuzumab (Herceptin® SC; H SC) is non-inferior to intravenous H (H IV) in terms of pathological complete response (pCR) in the breast for HER2-positive early breast cancer (EBC) (Jackisch, Lancet Oncol 2012). pCR/total pCR is associated with improved event-free survival in this setting, and H SC and H IV have comparable safety profiles (Jackisch, Lancet Oncol 2012; ASCO 2015). UmbHER1, a Phase IIIB, open-label, multinational umbrella study aims to assess the safety and tolerability of H SC in a broader patient population, including those with EBC or metastatic BC (MBC) treated with or without chemotherapy (CT) or pertuzumab (PERJETA®). UmbHER1 is composed of five EBC and two MBC studies; we present pooled interim safety data from the five EBC studies.


The EBC UmbHER1 studies are: NCT01940497 (neoadjuvant–adjuvant H SC + CT; N = 228), NCT01926886 (neoadjuvant–adjuvant H IV + H SC; N = 102), NCT02194166 (adjuvant H IV + H SC; N = 90), NCT01964391 (neoadjuvant–adjuvant H SC ± CT; N = 174), NCT02040935 (adjuvant H SC; N = 125). In all studies, H SC was administered as a 600 mg fixed dose and given every 3 weeks until progression/unacceptable toxicity/withdrawal (18 cycles/1 year). The overall primary objective is safety and tolerability. Results are descriptive and include all treatment cycles (H SC, H IV and CT).


The EBC safety population comprises 719 patients. There were 8219 H SC cycles administered for EBC by data cut-off (27 November 2015). The overall adverse event (AE) profile in the EBC population is shown in the table. The most common grade 3–4 serious AE (SAE) was decreased ejection fraction (3 patients, all grade 3).

Patients, n (%) Overall EBC population N = 719

Grade 2 344 (48)

No new safety signals were identified with H SC, administered with or without CT for HER2-positive EBC, in this broad UmbHER1 population.
