Dual HER2 blockade with pertuzumab (P) and trastuzumab (T) in patients with HER2-positive metastatic breast cancer (mBC) relapsing after adjuvant treatment with T: results from a German non-interventional study (NIS) HELENA (NCT01777958).

Purpose: NIS HELENA documented outcomes in clinical routine practice of first-line therapy with P plus T and docetaxel (D) of patients with advanced HER2-positive BC and prior (neo)adjuvant T.

Methods: Between 06/2013 through 07/2016, 126 patients (in-label use of P at study start = full analysis set, FAS) in 81 German study sites were included. Intense documentation period was limited to 28 treatment cycles.

First-line bevacizumab-containing therapy for HER2-negative locally advanced/metastatic breast cancer: Real-world experience from >2000 patients treated in the multicentre AVANTI study.

Aim: The multicentre non-interventional AVANTI study assessed safety, effectiveness and patient-reported outcomes with approved first-line bevacizumab-containing regimens for HER2-negative locally recurrent/metastatic breast cancer (LR/MBC) in German routine oncology practice.

Methods: Eligible patients had HER2-negative LR/MBC, no bevacizumab contraindications and no prior chemotherapy for LR/MBC. Chemotherapy schedule, diagnostics and follow-up were at physicians' discretion.

Protroca: A Noninterventional Study on Prophylactic Lipegfilgrastim against Chemotherapy-Induced Neutropenia in Nonselected Breast Cancer Patients.

Background: Protroca evaluated the efficacy and safety of primary and secondary prophylaxis of neutropenia with lipegfilgrastim (Lonquex®) in breast cancer patients receiving neoadjuvant or adjuvant chemotherapy (CT).

Patients And Methods: Of the 255 patients enrolled, 248 patients were evaluable for the intent-to-treat (ITT) and 194 patients for the per-protocol set. Primary and secondary end points after lipegfilgrastim treatment were assessed.

Resumption of Trastuzumab in Patients With Disease Recurrence After (Neo-) Adjuvant Anti-HER2-therapy in Patients With HER2-positive Breast Cancer.

Background/aim: HER2-positive breast cancers eventually relapse in about one third of patients. Is anti-HER2-directed therapy with Herceptin® (trastuzumab) effective in re-treatment? Between 2008 and 2018, 216 patients with recurrent HER2-positive breast cancer (BC) were re-treated with Herceptin (HER) during first-line therapy. This study assessed the effectiveness and tolerability of re-treatment with HER.

Topical azithromycin for the prevention of Lyme borreliosis: a randomised, placebo-controlled, phase 3 efficacy trial.

Background: Lyme borreliosis develops in 1-5% of individuals bitten by ticks, but with a diagnostic gap affecting up to 30% of patients, a broadly applicable pharmacological prevention strategy is needed. Topical azithromycin effectively eradicated Borrelia burgdorferi sensu lato from the skin in preclinical studies. We assessed its efficacy in human beings.
