Efficacy and Safety of First-Line Bevacizumab (BEV) Combined with Paclitaxel (PAC) According to Age: Subpopulation Analysis of a Large, Multicenter, …
2009
Abstract Background: In three randomized phase III trials (E2100, AVADO, RIBBON-1), the combination of Bev with taxane-based therapy significantly improved PFS and response rate versus taxane alone in HER2-negative MBC. Subpopulation analysis of AVADO suggested that the magnitude of the benefit derived from Bev was similar in older and younger pts (≥65 vs <65 years). To gain further information on the safety and efficacy of first-line Bev–pac in older pts treated in the real-life setting, we conducted a subpopulation analysis of data from an ongoing multicenter non-interventional study initiated after the approval of Bev in Germany. Materials and methods: Pts who had received no prio…
Abstract P6-12-02: Phase Ib dose-escalation study of an Akt inhibitor ipatasertib (Ipat) in combination with docetaxel (Doc) or paclitaxel (Pac) in p…
2015
Abstract Background: The Akt pathway is frequently aberrantly activated in MBC (e.g. via PTEN loss, and/or alterations of PIK3CA, AKT1, or AKT3); additionally, Akt activation may occur in response to chemotherapy, leading to cell survival and chemoresistance. Ipat (GDC-0068) is a potent oral, ATP-competitive inhibitor of all Akt isoforms. In preclinical models, Ipat synergistically combined with taxanes. In the Phase I dose-escalation single agent study, Ipat was given to pts including MBC, and downregulated Akt signaling at doses ≥ 100 mg. Methods: Eligible pts with MBC, treated with up to 3 prior systemic chemotherapy regimens, received Doc 75 mg/m2 intravenously (IV) on Day 1 with escala…
Distinct HR expression patterns significantly affect the clinical behavior of metastatic HER2+ breast cancer and degree of benefit from novel anti-HE…

We analyzed data from 738 HER2‐positive metastatic breast cancer (mbc) patients treated with pertuzumab‐based regimens and/or T‐DM1 at 45 Italian centers. Outcomes were explored in relation to tumor subtype assessed by immunohistochemistry (IHC). The median progression‐free survival at first‐line (mPFS1) was 12 months. Pertuzumab as first‐line conferred longer mPFS1 compared to other first‐line treatments (16 vs. 9 months, p = 0.0001), regardless of IHC subtype. Median PFS in second‐line (mPFS2) was 7 months, with no difference by IHC subtype, but it was more favorable with T‐DM1 compared to other agents (7 vs. 6 months, p = 0.03). There was no PFS2 gain in patients with tumors expressing b…
Eribulin (E) and capecitabine (C), a combined treatment schedule in elderly metastatic breast cancer (EMBC): Efficacy and safety evaluation (E&S).
2014
e20513 Background: E mesylate, a nontaxane microtubule dynamics inhibitor, was approved in the U.S in 2010 for the treatment of MBC who have previously received at least 2 MBC chemo regimens, inclu...
Abstract PD1-05: Latest findings from the breast cancer cohort in SUMMIT - a phase 2 ‘basket’ trial of neratinib + trastuzumab + fulvestrant for HER2…
2021
Abstract Background: HER2 mutations are oncogenic in hormone receptor positive (HR+) metastatic breast cancer (MBC), and may confer resistance to prior endocrine therapy but retain sensitivity to neratinib. Neratinib is an oral, irreversible, pan-HER tyrosine kinase inhibitor with clinical activity either as a single agent or in combination with fulvestrant in HER2-mutated, HER2-non-amplified MBC. Genomic analyses suggest that acquired resistance to neratinib can occur via additional HER2 alterations, which may alter HER2-pathway signaling. We investigated whether dual HER2-targeted therapy could improve clinical benefit in a cohort of patients with HER2-mutant, HR+ MBC treated with neratin…

9540 Background: E mesylate, a nontaxane microtubule dynamics inhibitor is widely prescribed for MBC pts pretreated with at least 1-2 lines of chemotherapy, including anthracyclines and taxanes (A&...
Metronomic Chemotherapy for Metastatic Breast Cancer.
2021
<b><i>Background:</i></b> As disease control and quality of life play a leading role in metastatic breast cancer (MBC), metronomic chemotherapy (MCT) is gaining popularity alongside conventional chemotherapy (CCT) and targeted therapies. <b><i>Summary:</i></b> MCT, defined as continuous administration of low-dose chemotherapeutic agents, is accepted as a therapy that exerts its effects via immunomodulation, anti-angiogenesis and direct cytotoxic effects. Oral administration of MCT is safe, easy to handle, and allows for flexible drug dosing. Dose accumulations associated with non-tolerable side effects are rare, so the medication can be admini…
Abstract PS5-12: Preliminary correlative analysis of clinical outcomes with PIK3CA mutation (mut) status from a phase I/Ib study of GDC-0077 in patie…
2021
Abstract Background Mutations in p110α, encoded by PIK3CA, are present in ~40% of HR+/HER2- BCs. GDC-0077, a PI3Kα-selective inhibitor and mutant PI3Kα degrader, elicits antitumor activity in PIK3CAmut preclinical models as a single agent and when combined with endocrine therapy (ET). New evidence suggests BCs harboring multiple PIK3CAmut exhibit increased signaling through the PI3K/AKT pathway and are more sensitive to PI3Kα inhibitors compared with BCs with a single PIK3CAmut. We report a preliminary analysis of PIK3CAmut status with clinical outcomes from an ongoing study of GDC-0077 alone or with ET (letrozole/fulvestrant) ± palbociclib (palbo) in pts with PIK3CAmut HR+/HER2- mBC (NCT03…
Abstract PD3-6: ConvertHER: Evolution of genomic alterations from primary to metastatic breast cancer
2015
Abstract Background: Changes in breast cancer receptor status over disease progression and treatment have been described to a point that could alter response to therapy. There is growing interest in delivering biomarker/genomically-based targeted therapies. We aimed to determine the concordance of genomic alterations between primary (P) and metastatic (M) breast cancer in a prospective collection study. Methods: Targeted capture and next-generation sequencing was performed on formalin-fixed paraffin-embedded (FFPE) samples, profiling 202 cancer relevant genes in 61 pairs (primary and corresponding recurrence/metastasis). Tumors were classified at baseline as [hormone receptor (HR)+/HER2-, H…
Abstract OT-31-01: A phase II study to evaluate the efficacy and safety of pembrolizumab plus carboplatin in BRCA-related metastatic breast cancer: P…
2021
Abstract Background Considering the high proportion of tumor-infiltrating lymphocytes (TILs) in BRCA-related breast cancer, we expect that PD-1 pathway is highly expressed and PD-1 antagonist pembrolizumab could provide clinical activity in this kind of tumor. Furthermore, BRCA-related breast cancers are known to be more sensitive to platinum-derived drugs. Thus the association between Pembrolizumab and Carboplatin in metastatic BRCA-related breast cancer seems to be active in this setting of patients. This study will evaluate the safety and the efficacy of Pembrolizumab associated with Carboplatin in BRCA mutated or with unknown mutations metastatic breast cancer patients. Study and Statis…
