Multiscaling and the classification of continuous phase transitions

1992

Multiscaling of the free energy is obtained by generalizing the classification of phase transitions proposed by Ehrenfest. The free energy is found to obey a new generalized scaling form which contains as special cases standard and multiscaling forms. The results are obtained by analytic continuation from the classification scheme of Ehrenfest.

The GiSAS study: Rationale and design of a pragmatic randomized controlled trial on aripiprazole, olanzapine and haloperidol in the long-term treatme…

2011

Given the controversy about the comparative efficacy of first- compared with second-generation antipsychotics in the treatment of schizophrenia, more large-scale evidence is needed to guide clinicians in their prescriptions. Most randomized controlled trials (RCTs) were conducted in centers of excellence on highly selected samples, poorly representative of real-world patients, and often suffered conflicts of interest as they were sponsored by drug companies. The primary aim of the present study is to compare the effectiveness of haloperidol, olanzapine and aripiprazole in a representative sample of schizophrenia patients. The GiSAS trial is an open-label, independent, pragmatic RCT in Itali…

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…

PDCT-08. SUPERIOR OUTCOME FOR BRAF V600E PEDIATRIC GLIOMAS TREATED WITH TARGETED BRAF INHIBITION

2019

Abstract BACKGROUND Children with pediatric low grade glioma’s (PLGG) harboring BRAF V600E mutation have poor outcome due to relative resistance to chemo-radiation and higher risk of malignant transformation. However, the role of targeted BRAF inhibition in these tumors is poorly defined. METHODS We assembled an international cohort of children with BRAF V600E mutant gliomas treated with BRAF inhibition, from 29 centers participating in the PLGG taskforce, and collected response, survival and molecular parameters. RESULTS Sixty-seven patients were treated with BRAFi (56 PLGG and 11 high grade gliomas) for a median time of 17.4 months (6 – 61 months), with 13 PLGG treated upfront. Objective …

Abstract PS11-05: Updated data from SERENA-1: A Phase 1 dose escalation and expansion study of the next generation oral SERD AZD9833 as a monotherapy…

2021

Abstract Background: AZD9833 is an oral selective estrogen receptor (ER) antagonist and degrader (SERD) in Phase 2 clinical development for the treatment of ER+ HER2− breast cancer. Here we report data from Parts C and D of the ongoing Phase 1 study (SERENA-1) examining AZD9833 in combination with palbociclib, together with updated data from Parts A and B examining AZD9833 monotherapy. Methods: SERENA-1 (NCT03616587) is an ongoing open-label Phase 1 study of AZD9833 in pre- and post-menopausal women with ER+, HER2− advanced breast cancer who have previously received ≥1 endocrine therapy and ≤2 prior chemotherapies. Prior treatment with fulvestrant and/or CDK4/6 inhibitors was permitted. The…

A Prognostic Model for Estimating the Time to Virologic Failure in HIV-1 Infected Patients Undergoing a New Combination Antiretroviral Therapy Regimen

2011

Abstract Background HIV-1 genotypic susceptibility scores (GSSs) were proven to be significant prognostic factors of fixed time-point virologic outcomes after combination antiretroviral therapy (cART) switch/initiation. However, their relative-hazard for the time to virologic failure has not been thoroughly investigated, and an expert system that is able to predict how long a new cART regimen will remain effective has never been designed. Methods We analyzed patients of the Italian ARCA cohort starting a new cART from 1999 onwards either after virologic failure or as treatment-naïve. The time to virologic failure was the endpoint, from the 90th day after treatment start, defined as the firs…

Associations of ofatumumab exposure and treatment outcomes in patients with untreated CLL receiving chemoimmunotherapy

2016

Relationships between patient characteristics, ofatumumab pharmacokinetics, and treatment outcomes were investigated in this phase 2 trial of ofatumumab plus fludarabine and cyclophosphamide (FC) in untreated chronic lymphocytic leukemia. Patients were randomized 1:1 to receive 500 or 1000 mg ofatumumab (Cycle 1; 300 mg) plus FC every 4 weeks for six cycles. Median C(max) and C(trough) values were similar at Cycle 1 regardless of the ultimate clinical outcome. At later doses, these values were higher for patients with complete response (CR) than for other patients. Higher C(max) and C(trough) values at Cycles 3 and 6 were significantly associated with an increased likelihood of CR, whereas …

Regorafenib Efficacy After Sorafenib in Patients With Recurrent Hepatocellular Carcinoma After Liver Transplantation:A Retrospective Study

2021

Background and aim Safety of regorafenib in hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT) has been recently demonstrated. We aimed to assess the survival benefit of regorafenib compared to best supportive care (BSC) in LT-patients after sorafenib discontinuation. Methods This observational multicenter retrospective study included LT-patients with HCC-recurrence who discontinued first-line sorafenib. Group-1 was constituted by regorafenib-treated patients, while control group was selected among patients treated with best supportive care (BSC) due to unavailability of second-line options at the time of sorafenib discontinuation and who were sorafenib-tolerant prog…
