Palbociclib combined with endocrine therapy in heavily pretreated HR/HER2 advanced breast cancer patients: Results from the compassionate use program in Spain (PALBOCOMP).

Background: This study evaluated efficacy and safety of palbociclib, a CDK4/6 inhibitor, in heavily-pretreated hormone receptor-positive and human epidermal growth factor receptor 2-negative (HR/HER2) metastatic breast cancer (mBC) patients during the compassionate use program in Spain from February 2015 to November 2017.

Patients And Methods: Patient data were collected retrospectively from 35 hospitals in Spain. Patients with HR/HER2 mBC who had progressed on ≥4 treatments for advanced disease were eligible.

Palbociclib and Trastuzumab in HER2-Positive Advanced Breast Cancer: Results from the Phase II SOLTI-1303 PATRICIA Trial.

Purpose: To assess palbociclib in combination with trastuzumab with or without endocrine therapy in patients with HER2-positive advanced breast cancer.

Patients And Methods: PATRICIA is a prospective, open-label, multicenter phase II trial. Patients had received 2-4 prior lines of anti-HER2-based regimens.

Phase III study to evaluate patient's preference of subcutaneous versus intravenous trastuzumab in HER2-positive metastatic breast cancer patients: Results from the ChangHER study (GEICAM/2012-07).

Objective: We compared patients' preferences for intravenous (IV-t) versus subcutaneous (SC-t) trastuzumab administration.

Methods: Phase III, open-label, multicentre study in HER2-positive metastatic breast cancer. Patients were receiving IV-t for at least 4 months without progression.

A Pilot, Phase II, Randomized, Open-Label Clinical Trial Comparing the Neurotoxicity of Three Dose Regimens of Nab-Paclitaxel to That of Solvent-Based Paclitaxel as the First-Line Treatment for Patients with Human Epidermal Growth Factor Receptor Type 2-Negative Metastatic Breast Cancer.

Background: This study aimed to characterize the neurotoxicity of three different regimens of nab-paclitaxel compared with a standard regimen of solvent-based (sb) paclitaxel for the first-line treatment of HER2-negative metastatic breast cancer based on the Total Neurotoxicity Score (TNS), a tool specifically developed to assess chemotherapy-induced neurotoxicity.

Materials And Methods: This was a randomized, open-label study testing 4-week cycles of 80 mg/m sb-paclitaxel (PACL80/w) on days 1, 8, and 15; 100 mg/m nab-paclitaxel on days 1, 8, and 15 (NAB100/w); 150 mg/m nab-paclitaxel on days 1, 8, and 15 (NAB150/w); and 150 mg/m nab-paclitaxel on days 1 and 15 (NAB150/2w). In addition to the TNS, neuropathy was assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE).
