Outcomes According to ALK Status Determined by Central IHC or FISH in Patients with ALK-Positive NSCLC Enrolled in the Phase III ALEX Study.

Introduction: We retrospectively examined progression-free survival (PFS) and response by ALK fluorescence in-situ hybridization (FISH) status in patients with advanced ALK immunohistochemistry (IHC)-positive non-small-cell lung cancer (NSCLC) in the ALEX study.

Methods: 303 treatment-naïve patients were randomized to receive twice-daily alectinib 600 mg or crizotinib 250 mg. ALK status was assessed centrally using Ventana ALK (D5F3) CDx IHC and Vysis ALK Break Apart FISH Probe Kit.

Results of a Dose-Finding Phase 1b Study of Subcutaneous Atezolizumab in Patients With Locally Advanced or Metastatic Non-Small Cell Lung Cancer.

Intravenous (IV) atezolizumab is approved for non-small cell lung and other cancers. Subcutaneous (SC) atezolizumab coformulated with recombinant human hyaluronidase, a permeation enhancer for SC dispersion and absorption, is being developed to improve treatment options, reduce burden, and increase efficiency for patients and practitioners. IMscin001 (NCT03735121), a 2-part, open-label, global, multicenter, phase 1b/3 study, is evaluating the pharmacokinetics (PK), safety, and efficacy of SC atezolizumab.

Outcomes According to ALK Status Determined by Central Immunohistochemistry or Fluorescence In Situ Hybridization in Patients With ALK-Positive NSCLC Enrolled in the Phase 3 ALEX Study.

Introduction: We retrospectively examined progression-free survival (PFS) and response by ALK fluorescence in situ hybridization (FISH) status in patients with advanced ALK immunohistochemistry (IHC)-positive NSCLC in the ALEX study.

Methods: A total of 303 treatment-naive patients were randomized to receive twice-daily alectinib 600 mg or crizotinib 250 mg. ALK status was assessed centrally using Ventana ALK (D5F3) CDx IHC and Vysis ALK Break Apart FISH Probe Kit.

Bevacizumab, temozolomide, and radiotherapy for newly diagnosed glioblastoma: comprehensive safety results during and after first-line therapy.

Background: The proposed use of bevacizumab with radiotherapy/temozolomide for newly diagnosed glioblastoma raised potential safety concerns. Bevacizumab has been linked with stroke, bleeding events, and wound-healing complications in other tumor types; these events are of particular concern for glioblastoma (highly vascular tumors that are usually resected). Published data on the interaction of bevacizumab with radiotherapy/temozolomide are also limited.

Improving outcomes of acute invasive Aspergillus rhinosinusitis in patients with hematologic malignancies or aplastic anemia: the role of voriconazole.

We evaluated the outcomes of patients with hematologic diseases diagnosed with acute invasive Aspergillus rhinosinusitis comparing a group of patients diagnosed after voriconazole was available at our center with a historical group of patients diagnosed before voriconazole was available. Voriconazole use was associated with a decrease in mortality and earlier clinical response.

Does antibiotic exposure increase the risk of methicillin-resistant Staphylococcus aureus (MRSA) isolation? A systematic review and meta-analysis.

Background: Current evidence does not provide a clear definition of the association between methicillin-resistant Staphylococcus aureus (MRSA) isolation and previous antibiotic use. A systematic review was performed to determine whether antibiotic exposure is a risk factor for the isolation of MRSA.

Methods: MEDLINE and EMBASE databases were searched to identify studies published between 1976 and 2007 on the role of antibiotics as a risk factor for MRSA isolation in adult patients.
