Adjuvant anastrozole versus exemestane versus letrozole, upfront or after 2 years of tamoxifen, in endocrine-sensitive breast cancer (FATA-GIM3): a randomised, phase 3 trial

Background: Uncertainty exists about the optimal schedule of adjuvant treatment of breast cancer with aromatase inhibitors and, to our knowledge, no trial has directly compared the three aromatase inhibitors anastrozole, exemestane, and letrozole. We investigated the schedule and type of aromatase inhibitors to be used as adjuvant treatment for hormone receptor-positive early breast cancer. Methods: FATA-GIM3 is a multicentre, open-label, randomised, phase 3 trial of six different treatments in postmenopausal women with hormone receptor-positive early breast cancer. Eligible patients had histologically confirmed invasive hormone receptor-positive breast cancer that had been completely remov…

A phase IB, multicenter, open-label study to assess the safety, tolerability, and efficacy of the pleiotropic pathway modifier CC122 administered orally to patients with advanced HCC.

379 Background: CC122 is a novel cereblon-modulating agent with multiple biologic activities including potent immunomodulatory and antiangiogenic effects. CC-122 binding to cereblon promotes ubiquitination and subsequent degradation of lymphoid transcription factors Ikaros and Aiolos resulting in activation of T cells. Methods: Following establishment of oral CC122 3 mg daily (QD) as the MTD in phase 1a (Blood 122:2905 2013), an expansion cohort of advanced Hepatocellular Carcinoma (HCC) subjects was enrolled. All subjects had progressed on or were intolerant to sorafenib. Efficacy was assessed per RECIST 1.1 criteria. Results: As of Jan. 13, 2016, 25 advanced HCC subjects were enrolled. T…

Fasting-Mimicking Diet Is Safe and Reshapes Metabolism and Antitumor Immunity in Patients with Cancer.

Abstract In tumor-bearing mice, cyclic fasting or fasting-mimicking diets (FMD) enhance the activity of antineoplastic treatments by modulating systemic metabolism and boosting antitumor immunity. Here we conducted a clinical trial to investigate the safety and biological effects of cyclic, five-day FMD in combination with standard antitumor therapies. In 101 patients, the FMD was safe, feasible, and resulted in a consistent decrease of blood glucose and growth factor concentration, thus recapitulating metabolic changes that mediate fasting/FMD anticancer effects in preclinical experiments. Integrated transcriptomic and deep-phenotyping analyses revealed that FMD profoundly reshapes antican…

HSPH1 inhibition downregulates Bcl-6 and c-Myc and hampers the growth of human aggressive B-cell non-Hodgkin lymphoma

We have shown that human B-cell non-Hodgkin lymphomas (B-NHLs) express heat shock protein (HSP)H1/105 in function of their aggressiveness. Here, we now clarify its role as a functional B-NHL target by testing the hypothesis that it promotes the stabilization of key lymphoma oncoproteins. HSPH1 silencing in 4 models of aggressive B-NHLs was paralleled by Bcl-6 and c-Myc downregulation. In vitro and in vivo analysis of HSPH1-silenced Namalwa cells showed that this effect was associated with a significant growth delay and the loss of tumorigenicity when 10(4) cells were injected into mice. Interestingly, we found that HSPH1 physically interacts with c-Myc and Bcl-6 in both Namalwa cells and pr…

Neoadjuvant eribulin mesylate following anthracycline and taxane in triple negative breast cancer: Results from the HOPE study

BackgroundEribulin mesylate (E) is indicated for metastatic breast cancer patients previously treated with anthracycline and taxane. We argued that E could also benefit patients eligible for neoadjuvant chemotherapy.MethodsPatients with primary triple negative breast cancer ≥2 cm received doxorubicin 60 mg/m2 and paclitaxel 200 mg/m2 x 4 cycles (AT) followed by E 1.4 mg/m2 x 4 cycles. Primary endpoint was pathological complete response (pCR) rate; secondary and explorative endpoints included clinical/metabolic response rates and safety, and biomarker analysis, respectively. Using a two-stage Simon design, 43 patients were to be included provided that 4 of 13 patients had achieved pCR in the…

Abstract A18: miR-9 and miR-200 regulate PDGFRβ-mediated endothelial differentiation of neoplastic cells in triple-negative breast cancer

Abstract Tumor vascularization is a fundamental step in solid tumor progression and is orchestrated by different pathways of vasculogenesis. In malignant tumors, neoplastic cells can differentiate into endothelial-like cells acquiring the expression of endothelial markers (i.e. CD31 and CD34) and participating in the formation of vascular-like structures that functionally deliver oxygen and nutrients to the tumor site. We recently identified PDGFRβ as an important player of this process in triple negative breast cancer (TNBC). Interestingly, increasing evidence supported a connection between PDGFRβ and epithelial to mesenchymal transition (EMT), important step for the endothelial trans-diff…

C1-02: Randomized Phase II study of vandetanib alone or in combination with carboplatin and paclitaxel as 1st-line treatment for advanced NSCLC

miR-9 and miR-200 regulate PDGFRβ-mediated endothelial differentiation of tumor cells in triple-negative breast cancer

Abstract Organization of cancer cells into endothelial-like cell-lined structures to support neovascularization and to fuel solid tumors is a hallmark of progression and poor outcome. In triple-negative breast cancer (TNBC), PDGFRβ has been identified as a key player of this process and is considered a promising target for breast cancer therapy. Thus, we aimed at investigating the role of miRNAs as a therapeutic approach to inhibit PDGFRβ-mediated vasculogenic properties of TNBC, focusing on miR-9 and miR-200. In MDA-MB-231 and MDA-MB-157 TNBC cell lines, miR-9 and miR-200 promoted and inhibited, respectively, the formation of vascular-like structures in vitro. Induction of endogenous miR-9…

This study investigated the efficacy and safety of pimasertib (MEK1/MEK2 inhibitor) versus dacarbazine (DTIC) in patients with untreated NRAS-mutated melanoma. Phase II, multicenter, open-label trial. Patients with unresectable, stage IIIc/IVM1 NRAS-mutated cutaneous melanoma were randomized 2:1 to pimasertib (60 mg

Abstract B157: OX40 expression in tumor-associated Tregs as a potential prognostic biomarker and immunotherapeutic target in ovarian cancer

Abstract Background - Treatment of ovarian cancer remains very challenging, with 80-85% of the cases still dying after relapse to standard chemotherapy, and alternative treatments are urgently needed. Expansion of regulatory T cells (Tregs) is considered the major factor limiting spontaneous immune responses to ovarian cancer. Agonist antibodies against the co-stimulatory receptor OX40 have recently demonstrated to abrogate Treg functions and are under clinical evaluation. We thus studied whether OX40 constituted a valid target of ovarian cancer-associated Tregs. Methods -Treg immunophenotypic analyses were performed by flow cytometry in ascites and ovarian cancer specimens and studied in a…

Phase II Study of the Etoposide, Leucovorin and Fluorouracil Combination for Patients with Advanced Gastric Cancer Unsuitable for Aggressive Chemotherapy

Many patients with advanced gastric cancer cannot be treated with intensive chemotherapy. In an attempt to provide a feasible regimen for such patients, the combination of etoposide, leucovorin and fluorouracil (ELF) has been developed with promising results. The present study involved 42 patients with advanced gastric cancer who where unsuitable for cisplatin- or anthracycline-containing regimens because of their age (24 patients over 65 years), poor performance status (12) or the presence of concomitant illness (6). The treatment consisted of etoposide 120 mg/m2 i.v., 1-leucovorin 150 mg/m2 i.v. and fluorouracil 500 mg/m2 i.v. for 3 consecutive days every 3 weeks. Among the 41 evaluable p…
