Randomized, Double-Blind Study of Sonidegib (Lde225) in Patients (Pts) with Advanced Basal Cell Carcinoma (Bcc)
ABSTRACT Aim: The BOLT phase 2 study, comparing 2 doses of sonidegib, a hedgehog pathway inhibitor (HhPI), in pts with advanced BCC (aBCC; NCT01327053), met its primary endpoint of objective response rate ≥30% in both arms in analyses of data collected up to 6 mo after randomization of the last pt (June 28, 2013, cutoff; median follow-up [f/u], 13.9 mo; Migden, ASCO 2014). Associations of GLI1 (marker of Hh pathway activation) with clinical outcome (as of June 28, 2013) and updated 12-mo efficacy and safety data (Dec 31, 2013, cutoff; median f/u, 20.0 mo) are presented. Methods: Pts with locally advanced BCC (LaBCC; n = 194) not amenable to curative surgery or radiation or metastatic BCC (m…
International consensus guidelines for scoring the histopathological growth patterns of liver metastasis
BACKGROUND: Liver metastases present with distinct histopathological growth patterns (HGPs), including the desmoplastic, pushing and replacement HGPs and two rarer HGPs. The HGPs are defined owing to the distinct interface between the cancer cells and the adjacent normal liver parenchyma that is present in each pattern and can be scored from standard haematoxylin-and-eosin-stained (H&E) tissue sections. The current study provides consensus guidelines for scoring these HGPs.METHODS: Guidelines for defining the HGPs were established by a large international team. To assess the validity of these guidelines, 12 independent observers scored a set of 159 liver metastases and interobserver var…
Copy-number and targeted sequencing analyses to identify distinct prognostic groups: Implications for patient selection to targeted therapies amongst anti-endocrine therapy resistant early breast cancers.
524 Background: Hormone receptor positive breast cancer is a therapeutic challenge. Despite optimal anti-endocrine therapies, most breast cancer deaths follow a diagnosis of early luminal cancer. To understand the impact of multiple aberrations in the context of current therapy, we assessed the prognostic ability of genomic signatures as a putative stratification tool to targeted therapies. Methods: This a priori study is based on molecular pathways which might predict response to targeted therapies. DNA from 420 patients from the phase III TEAM pathology cohort were used. Patients with a distant recurrence within 5 years were matched by clinical variables to those disease-free at follow u…
Long‐term efficacy and safety of sonidegib in patients with advanced basal cell carcinoma: 42‐month analysis of the phase II randomized, double‐blind BOLT study
Background: Basal cell carcinomas (BCCs) exhibit aberrant activation of the hedgehog pathway. Sonidegib is a hedgehog pathway inhibitor approved for the treatment of locally advanced BCC (laBCC) and metastatic BCC (mBCC) based on primary results of the BOLT study [Basal Cell Carcinoma Outcomes with LDE225 (sonidegib) Treatment]. Objectives: This is the final 42-month analysis of the BOLT study, evaluating the efficacy and safety of sonidegib. Methods: Adults with no prior hedgehog pathway inhibitor therapy were randomized in a 1 : 2 ratio to sonidegib 200 mg or 800 mg once daily. Treatment continued for up to 42 months or until disease progression, unacceptable toxicity, death, study termin…
Abstract CT301: A phase Ib study to evaluate RO7198457, an individualized Neoantigen Specific immunoTherapy (iNeST), in combination with atezolizumab in patients with locally advanced or metastatic solid tumors
Abstract Background: Neoantigens arising from somatic mutations are attractive targets for cancer immunotherapy as they may be recognized as foreign by the immune system. RO7198457, a systemically administered RNA-Lipoplex iNeST was designed to stimulate T cell responses against neoantigens. A first-in-human Phase Ib study of RO7198457, in combination with the aPD-L1 antibody atezolizumab is being conducted in patients with locally advanced or metastatic solid tumors. Methods: RO7198457 is manufactured on a per-patient basis and contains up to 20 tumor-specific neoepitopes. Nine doses of RO7198457 were administered i.v. in weekly and bi-weekly intervals during the 12-week induction stage an…
