Efficacy and Safety of a 2-Month Formulation of Aripiprazole Lauroxil With 1-Day Initiation in Patients Hospitalized for Acute Schizophrenia Transitioned to Outpatient Care: Phase 3, Randomized, Double-Blind, Active-Control ALPINE Study.

Objective: Evaluate efficacy and safety of a 2-month formulation of aripiprazole lauroxil (AL) with 1-day initiation during hospitalization for acute exacerbation of schizophrenia followed by transition to outpatient care.

Methods: The phase 3b double-blind Aripiprazole Lauroxil and Paliperidone palmitate: INitiation Effectiveness (ALPINE) study was conducted from November 2017 to March 2019. Adults with acute schizophrenia according to DSM-5 criteria were randomized (1:1) to AL (AL NanoCrystal Dispersion + oral aripiprazole 30 mg, day 1; AL 1,064 mg, day 8 and every 8 weeks [q8wk]) or paliperidone palmitate (PP 234 mg, day 1; PP 156 mg, day 8 and then q4wk) for 25 weeks.

Application of a high-throughput screening procedure with PEG-induced precipitation to compare relative protein solubility during formulation development with IgG1 monoclonal antibodies.

Protein solubility is a critical attribute in monoclonal antibody (mAb) formulation development as insolubility issues can negatively impact drug stability, activity, bioavailability, and immunogenicity. A high-throughput adaptation of an experimental method previously established in the literature to determine apparent protein solubility is described, where polyethylene glycol (PEG) is used to reduce protein solubility in a quantitatively definable manner. Utilizing an automated, high-throughput system, an immunoglobulin G (IgG)1 mAb in a variety of buffer conditions was exposed to increasing concentrations of PEG and the amount of protein remaining in solution was determined.

Combination of automated high throughput platforms, flow cytometry, and hierarchical clustering to detect cell state.

Background: This study examined whether hierarchical clustering could be used to detect cell states induced by treatment combinations that were generated through automation and high-throughput (HT) technology. Data-mining techniques were used to analyze the large experimental data sets to determine whether nonlinear, non-obvious responses could be extracted from the data.

Methods: Unary, binary, and ternary combinations of pharmacological factors (examples of stimuli) were used to induce differentiation of HL-60 cells using a HT automated approach.

The prevalence of germline BRCA1 and BRCA2 mutations in young women with breast cancer undergoing breast-conservation therapy.

Background: Germline mutations of BRCA1 and BRCA2 increase the risk for breast cancer. Mutation carriers selecting breast-conservation therapy (BCT) for treatment of operable breast cancer experience a higher rate of new primary breast cancers. We sought to determine the frequency of BRCA1/BRCA2 mutations in women who underwent BCT.

Respiratory maneuvers decrease irradiated cardiac volume in patients with left-sided breast cancer.

Late cardiac morbidity and mortality among left breast cancer survivors treated with radiation therapy is related to cardiac volume included in the radiation portals. To determine if respiratory maneuvers can help decrease cardiac volume included in the radiation portals for left-sided breast cancer, 17 women with breast cancer, who had undergone left breast radiation therapy, underwent cardiac magnetic resonance imaging (MRI). Cardiac volume within the radiation portals was assessed from a transverse stack of eight, 10-mm thick, contiguous slices, covering the entire heart and obtained during breathholding at (1) endtidal volume (ETid) and (2) deep inspiration.
