To evaluate the acute efficacy, safety, and tolerability of flexibly dosed ziprasidone in children and adolescents with Bipolar I Disorder (BD-I). Participants, 10-17 years of age, meeting The criteria, were randomized 1:1 in a 4-week double-blind (DB) study, to receive ziprasidone (20-80 mg/twice a day) or placebo. Some were then enrolled in a 26-week open-label extension (OLE) study.

Lack of an Effect of Supratherapeutic Dose of Venlafaxine on Cardiac Repolarization in Healthy Subjects.

This single-center, randomized, 3-way crossover thorough QT study evaluated the effect of steady-state supratherapeutic venlafaxine (Effexor) on cardiac repolarization. Fifty-four healthy adults received double-blinded extended-release venlafaxine 450 mg/d and placebo and open-label positive-control moxifloxacin 400 mg. The postdose QT intervals corrected for heart rate using the Fridericia formula (QTcF) were assessed on day 14 with an analysis of covariance using a mixed-effects model.

A Thorough QT Study to Evaluate the Effects of a Supratherapeutic Dose of Sertraline on Cardiac Repolarization in Healthy Subjects.

The effect of steady-state supratherapeutic sertraline (Zoloft) on QT interval was assessed in a single-center, randomized, 3-way crossover, double-blind, placebo- and moxifloxacin-controlled thorough QT study. Healthy adults received sertraline 400 mg/day, moxifloxacin 400 mg, and placebo, with a washout period (≥14 days) between treatments. A 12-lead electrocardiogram was recorded in triplicate before dosing and at selected time points up to 72 hours after dosing.

Objectives: To compare outcomes following tofacitinib withdrawal with outcomes of continuation.

Methods: In this phase 3 study (NCT01186744), patients received tofacitinib 5 mg (n = 331) or 10 mg (n = 335) twice daily for 24 weeks.

Adjunctive oral ziprasidone in patients with acute mania treated with lithium or divalproex, part 2: influence of protocol-specific eligibility criteria on signal detection.

Objectives: High failure rates of randomized controlled trials (RCTs) are well recognized but poorly understood. We report exploratory analyses from an adjunctive ziprasidone double-blind RCT in adults with bipolar I disorder (reported in part 1 of this article). Data collected by computer interviews and by site-based raters were analyzed to examine the impact of eligibility criteria on signal detection.

Adjunctive oral ziprasidone in patients with acute mania treated with lithium or divalproex, part 1: results of a randomized, double-blind, placebo-controlled trial.

Objective: To assess the efficacy and safety of adjunctive ziprasidone in subjects with acute mania treated with lithium or divalproex, with an inadequate response to the mood stabilizer.

Method: The study enrolled subjects aged 18-65 years who had a primary DSM-IV diagnosis of bipolar I disorder, with the most recent episode manic or mixed, with or without rapid cycling, and a Young Mania Rating Scale (YMRS) score ≥ 18. Subjects were randomized under double-blind conditions to receive ziprasidone, 20 to 40 mg (n = 226) or 60 to 80 mg (n = 232), or placebo (n = 222) twice a day for 3 weeks in addition to their mood stabilizer.

Switching from quetiapine to ziprasidone: a sixteen-week, open-label, multicenter study evaluating the effectiveness and safety of ziprasidone in outpatient subjects with schizophrenia or schizoaffective disorder.

Objective: The objectives of this study were to evaluate the effects of switching from quetiapine to ziprasidone on weight, safety, and effectiveness

Methods: In this study, 241 subjects with schizophrenia or schizo affective disorder who had been treated with quetiapine (≥300 mg/day) for ≥3 months with either suboptimal efficacy or poor tolerability were enrolled in a 16-week, open-label, flexible-dose trial, with a 16-week follow-up (total 32 weeks). Quetiapine was tapered and discontinued over the course of 2 weeks, while ziprasidone was titrated up and dosed at 40-80 mg b.i.

The effect of early versus delayed challenge after vaccination in controlling SHIV 89.6P infection.

We sought to determine how effectively a CD8+ T cell inducing vaccine controls SHIV-89.6P infection in rhesus macaques at a range of challenge times post-vaccination. To this end, twenty eight Mamu-A*01+ rhesus macaques were given replication incompetent human serotype 5 adenovirus vector expressing SIVmac239 gag DNA and boosted 24 weeks later.

Attenuation of simian immunodeficiency virus SIVmac239 infection by prophylactic immunization with dna and recombinant adenoviral vaccine vectors expressing Gag.

The prophylactic efficacy of DNA and replication-incompetent adenovirus serotype 5 (Ad5) vaccine vectors expressing simian immunodeficiency virus (SIV) Gag was examined in rhesus macaques using an SIVmac239 challenge. Cohorts of either Mamu-A*01(+) or Mamu-A*01(-) macaques were immunized with a DNA prime-Ad5 boost regimen; for comparison, a third cohort consisting of Mamu-A*01(+) monkeys was immunized using the Ad5 vector alone for both prime and boost. All animals, along with unvaccinated control cohorts of Mamu-A*01(+) and Mamu-A*01(-) macaques, were challenged intrarectally with SIVmac239.

Mapping and binding analysis of peptides derived from the tumor-associated antigen survivin for eight HLA alleles.

There is considerable interest in developing immunotherapeutic approaches to elicit tumor-specific CTL responses in cancer patients. Epitope-based approaches aim to deliver the antigenic peptides or epitopes recognized by CTLs rather than the intact tumor antigen. Many tumor-associated proteins are nonmutated self proteins for which the dominant peptide epitopes are usually poorly immunogenic.

Intracellular staining for HIV-specific IFN-gamma production: statistical analyses establish reproducibility and criteria for distinguishing positive responses.

The cellular immune response plays a pivotal role in controlling the spread of HIV-1 infection by lysing virally infected cells and producing potent antiviral cytokines, such as interferon-gamma (IFN-gamma). Flow cytometric methods have been established to evaluate the contribution of both CD4 and CD8 subsets of T lymphocytes to the immune response to HIV by measuring their production of intracellular IFN-gamma following brief antigenic stimulation. We present a statistical treatment of intracellular cytokine staining (ICS) data that is aimed at establishing the reproducibility and robustness of this assay for use in HIV clinical trials.

Antigen burden is major determinant of human immunodeficiency virus-specific CD8+ T cell maturation state: potential implications for therapeutic immunization.

The majority of untreated human immunodeficiency virus (HIV) type 1-infected individuals ultimately develop uncontrolled viremia and progressive disease. Cytotoxic T lymphocytes (CTLs) are known to play an important role in controlling HIV-1 replication, which has led to an increasing interest in augmenting conventional antiretroviral therapy with therapeutic vaccination. The successful development of a therapeutic vaccine will rely on the ability to correlate an aspect of the immune response with clinical outcome.

Disruption of the IFN-gamma cytokine network in chronic lymphocytic leukemia contributes to resistance of leukemic B cells to apoptosis.

Recent evidence indicates that the slowly expanding population of CD5+ B cells that characterizes chronic lymphocytic leukemia (CLL) results primarily from defects in responses to cytokines that regulate apoptosis (e.g. I1-4, TGF-beta, IFN-alpha, IFN-gamma).
