Abstract Text A subcutaneous formulation of trastuzumab has been developed, offering potential improvements in patient convenience and resource use compared with the standard intravenous infusion of the drug. We compared the pharmacokinetic profile, efficacy, and safety of the subcutaneous and intravenous formulations in patients with HER2-positive early breast cancer.The HannaH study was a phase 3, randomised, international, open-label, trial in the (neo)adjuvant setting. Patients with HER2-positive, operable, locally advanced or inflammatory breast cancer were randomly assigned to eight cycles of neoadjuvant chemotherapy administered concurrently with trastuzumab every 3 weeks either intravenously (8 mg/kg loading dose, 6 mg/kg maintenance dose) or subcutaneously (fixed dose of 600 mg); 1:1 ratio. Chemotherapy consisted of four cycles of docetaxel (75 mg/m(2)) followed by four cycles of fluorouracil (500 mg/m(2)), epirubicin (75 mg/m(2)), and cyclophosphamide (500 mg/m(2)), every 3 weeks. After surgery, patients continued trastuzumab to complete 1 year of treatment. Coprimary endpoints were serum trough concentration (C(trough)) at pre-dose cycle 8 before surgery (non-inferiority margin for the ratio between groups of 0·80) and pathological complete response (pCR; non-inferiority margin for the difference between groups of -12·5%), analysed in the per-protocol population. This study is registered with ClinicalTrials.gov, number NCT00950300.299 patients were randomly assigned to receive intravenous trastuzumab and 297 to receive subcutaneous trastuzumab. The geometric mean presurgery C(trough) was 51·8 μg/mL (coefficient of variation 52·5%) in the intravenous group and 69·0 μg/mL (55·8%) in the subcutaneous group. The geometric mean ratio of C(trough) subcutaneous to C(trough) intravenous was 1·33 (90% CI 1·24-1·44). 107 (40·7%) of 263 patients in the intravenous group and 118 (45·4%) of 260 in the subcutaneous group achieved a pCR. The difference between groups in pCR was 4·7% (95% CI -4·0 to 13·4). Thus subcutaneous trastuzumab was non-inferior to intravenous trastuzumab for both coprimary endpoints. The incidence of grade 3-5 adverse events was similar between groups. The most common of these adverse events were neutropenia (99 [33·2%] of 298 patients in the intravenous group vs 86 [29·0%] of 297 in the subcutaneous group), leucopenia (17 [5·7%] vs 12 [4·0%]), and febrile neutropenia (10 [3·4%] vs 17 [5·7%]). However, more patients had serious adverse events in the subcutaneous group (62 [21%] of 297 patients) than in the intravenous group (37 [12%] of 298); the difference was mainly attributable to infections and infestations (24 [8·1%] in the subcutaneous group vs 13 [4·4%] in the intravenous group). Four adverse events led to death (one in the intravenous group and three in the subcutaneous group), all of which occurred during the neoadjuvant phase. Of these, two--both in the subcutaneous group--were deemed to be treatment related.Subcutaneous trastuzumab, administered over about 5 min, has a pharmacokinetic profile and efficacy non-inferior to standard intravenous administration, with a similar safety profile to intravenous trastuzumab, and therefore offers a valid treatment alternative.F Hoffmann-La Roche.

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.
