The emergence of CDK4/6 inhibitors has changed the treatment algorithm for advanced/metastatic estrogen receptor-positive breast cancer. In pivotal trials of palbociclib, ribociclib, and abemaciclib, doubling in progression-free survival has been seen. All 3 agents in this class are now included in the NCCN Guidelines for Breast Cancer, and clinicians should be incorporating these agents into their treatment algorithms. The other important issue in this breast cancer setting is extended duration of endocrine therapy...

Background: Endocrine therapy is the cornerstone treatment for patients with hormone receptor-positive advanced breast cancer. We aimed to assess the effectiveness of various first-line endocrine monotherapies or combinations to determine the optimal sequence in a network meta-analysis. Materials and methods: We searched PubMed, EMBASE, and the Cochrane Library for randomized controlled trials (RCTs) from inception up to November 21, 2017. We included only RCTs that assessed the effectiveness of the following treatments as a monotherapy or in combination as the first-line treatment: tamoxifen, anastrozole, letrozole, exemestane, fulvestrant, palbociclib, and ribociclib...

PURPOSE: Outcome data on hormone receptor positive (HR+ ), human epidermal growth factor receptor 2 (HER2) nonamplified (HER2- ) metastatic breast cancer (MBC) treated with palbociclib after treatment with everolimus are lacking. The PALOMA-3 trial, showing benefit of palbociclib plus fulvestrant compared to fulvestrant alone in HR+ HER2- MBC after progression while receiving endocrine therapy excluded women previously treated with everolimus. The objective of this study was to examine outcomes of HR+ HER2- MBC with prior exposure to everolimus while receiving palbociclib-based therapy...

Palbociclib (PAB) is a CDK4/6 inhibitor and U. S Food and Drug Administration (FDA) granted regular approval for the treatment of hormone receptor (HR) positive, metastatic breast cancer in combination with an aromatase inhibitor in postmenopausal women. Metabolite identification is a crucial aspect during drug discovery and development as the drug metabolites may be pharmacologically active or possess toxicological activity. As there are no reports on the metabolism studies of the PAB, the present study focused on investigation of the in vitro and in vivo metabolic fate of the drug...

PURPOSE: Loss of cell cycle control is a hallmark of cancer, which can be targeted with agents, including Cyclin Dependent Kinase-4/6 (CDK4/6) kinase inhibitors that impinge upon the G1-S cell cycle checkpoint via maintaining activity of the retinoblastoma tumor suppressor (RB). This class of drugs is under clinical investigation for various solid tumor types, and has recently been FDA-approved for treatment of breast cancer. However, development of therapeutic resistance is not uncommon...

Palbociclib is a specific inhibitor of CDK4/6 and has been shown to provide a survival benefit in hormone receptor-positive advanced breast cancer. TCGA database reported that about half of gastric cancers exhibit abnormalities in cell-cycle-related molecules, suggesting that gastric cancer is a good candidate for palbociclib treatment; however, the antitumor effects and predictive markers of palbociclib in gastric cancer remain incompletely described. Herein, the effect and predictive markers of palbociclib on gastric cancer cells were investigated...

Cyclin-dependent kinase 4/6 inhibitors, which act by inhibiting progression from the G1 to S phases of the cell cycle, include palbociclib, ribociclib, abemaciclib, and trilaciclib. Palbociclib and ribociclib are currently food and drug administration-approved for use in combination with aromatase inhibitors in postmenopausal women with metastatic hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer. Palbociclib is also food and drug administration-approved for use in combination with fulvestrant in hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer progressing after endocrine therapy...

BACKGROUND: Rapidly evolving understanding of cancer biology has presented novel opportunities to translate that understanding into clinically relevant therapy. Palbociclib, a novel, first-in-class cyclin-dependent kinase (CDK) 4/6 inhibitor was approved in the USA in February 2015 for the treatment of advanced/metastatic breast cancer. We examined real-world evidence in the first year post approval to understand the clinical and demographic characteristics of patients treated with palbociclib in community oncology practices and the dosing, treatment, and complete blood count (CBC) monitoring patterns...

The cyclin D-cyclin-dependent kinase (CDK) 4/6-inhibitors (CDK4/6i) induce cell cycle arrest in the G1 phase what eventually can prevent the proliferation of cancer cells. The CDK4/6i have changed the landscape of treatment options for ER-positive, HER2-negative metastatic breast cancer. Currently, palbociclib, ribociclib, and abemaciclib are approved by the US Food and Drug Administration in this setting. This success encouraged the researchers to examine CDK4/6i activity in (neo)adjuvant setting. In this review, clinical data to date and ongoing clinical trials with palbociclib, ribociclib, and abemaciclib in the early breast cancer are discussed...

Bruton's tyrosine kinase (BTK) is a key regulator of the B-cell receptor signaling pathway, and aberrant B-cell receptor (BCR) signaling has been implicated in the survival of malignant B-cells. However, responses of the diffuse large B-cell lymphoma (DLBCL) to inhibitors of BTK (BTKi) are infrequent, highlighting the need to identify mechanisms of resistance to BTKi as well as predictive biomarkers. We investigated the response to the selective BTKi, tirabrutinib, in a panel of 64 hematopoietic cell lines...

Synovial sarcoma is a highly aggressive but rare form of soft tissue malignancy that primarily affects the extremities of the arms or legs, for which current chemotherapeutic agents have not been proven to be very effective. The cyclin-dependent kinase 4/6-retinoblastoma protein (CDK4/6-Rb) pathway of cell cycle control is known to be aberrant in a large proportion of cancers. Recently, CDK4 inhibitors have successfully been used pre-clinically for the treatment of many human cancers, and in 2015, following the success of clinical trials, the FDA approved the first selective CDK4/6 inhibitor, palbociclib, for the treatment of endocrine therapy resistant breast cancers...

Palbociclib is a CDK4/6 inhibitor approved for metastatic estrogen receptor-positive breast cancer. In addition to G1 cell cycle arrest, palbociclib treatment results in cell senescence, a phenotype that is not readily explained by CDK4/6 inhibition. In order to identify a molecular mechanism responsible for palbociclib-induced senescence, we performed thermal proteome profiling of MCF7 breast cancer cells. In addition to affecting known CDK4/6 targets, palbociclib induces a thermal stabilization of the 20S proteasome, despite not directly binding to it...

INTRODUCTION: Oncology drugs combined with standard therapies (so-called add-on therapies, e.g. bevacizumab, palbociclib) often receive negative recommendations regarding the legitimacy of public financing, issued by government agencies responsible for their assessment, i.e. health technology assessment agencies. The aim of the study was to estimate the scale of the problem related to the reimbursement of add-on therapies used in the treatment of breast and genitourinary cancers in Poland and in the world...

BACKGROUND: The APOBEC gene family of cytidine deaminases plays important roles in DNA repair and mRNA editing. In many cancers, APOBEC3B increases the mutation load, generating clusters of closely spaced, single-strand-specific DNA substitutions with a characteristic hypermutation signature. Some studies also suggested a possible involvement of APOBEC3A, REV1, UNG, and FHIT in molecular processes affecting APOBEC mutagenesis. It is important to understand how mutagenic processes linked to the activity of these genes may affect sensitivity of cancer cells to treatment...

PURPOSE: HR+/HER2- aromatase inhibitor-resistant metastatic breast cancer can be treated with everolimus and a second AI until the cancer recurs. Targeting these everolimus-resistant patients with the latest standard of care, CDK4/6 inhibitors, has not been clearly addressed. Understanding the signaling transduction pathways, which everolimus resistance activates, will elucidate the mechanisms and offer treatment strategies of everolimus resistance. METHODS: To mimic the clinical setting, letrozole-resistant cells were used to generate an everolimus-resistant model (RAD-R)...
