Safety, tolerability and pharmacokinetics of emodepside, a potential novel treatment for onchocerciasis (river blindness), in healthy male subjects.

Aims: Emodepside is an anthelmintic, originally developed for veterinary use. We investigated in healthy subjects the safety, and pharmacokinetics of a liquid service formulation (LSF) and immediate release (IR) tablet of emodepside in 2 randomised, parallel-group, placebo-controlled, Phase I studies.

Methods: Seventy-nine subjects in 10 cohorts in the single ascending dose study and 24 subjects in 3 ascending-dose cohorts in the multiple ascending dose study were enrolled.

Safety and efficacy of switching from adalimumab to sarilumab in patients with rheumatoid arthritis in the ongoing MONARCH open-label extension.

Objective: Evaluate open-label sarilumab monotherapy in patients with rheumatoid arthritis switching from adalimumab monotherapy in MONARCH (NCT02332590); assess long-term safety and efficacy in patients continuing sarilumab during open-label extension (OLE).

Methods: During the 48-week OLE, patients received sarilumab 200 mg subcutaneously once every 2 weeks. Safety (March 2017 cut-off) and efficacy, including patient-reported outcomes, were evaluated.

Safety and tolerability of subcutaneous sarilumab and intravenous tocilizumab in patients with rheumatoid arthritis.

Objective: Safety and efficacy of mAbs blocking the IL-6 receptor have been established in RA. This is the first analysis examining safety and tolerability of sarilumab and tocilizumab administered as single or multiple doses in patients with RA within the same study.

Methods: In ASCERTAIN, patients were randomized 1: 1: 2 to 24 weeks' double-blind sarilumab 150 or 200 mg every 2 weeks s.

Post Hoc Analysis of the Phase II/III APRIL-SLE Study: Association Between Response to Atacicept and Serum Biomarkers Including BLyS and APRIL.

Objective: To assess the relationship between treatment response, baseline biomarker levels, and atacicept exposure in patients with systemic lupus erythematosus (SLE) in the phase II/III APRIL-SLE study.

Methods: We performed a post hoc analysis of patients who received placebo, atacicept 75 mg, or atacicept 150 mg in a randomized, controlled, 52-week trial. Serum levels of BlyS and APRIL were measured at baseline, and serum levels of Ig and the numbers of naive B cells and plasma cells were measured at baseline and during treatment.

Contralateral knee effect on self-reported knee-specific function and global functional assessment: data from the Osteoarthritis Initiative.

Objective: To analyze the effect of contralateral knee pain on sensitivity of patient-reported outcomes and objectively measured functional performance tests in subjects with knee osteoarthritis (OA).

Methods: Subjects with discordant knee pain status (i.e.

Efficacy and safety of atacicept for prevention of flares in patients with moderate-to-severe systemic lupus erythematosus (SLE): 52-week data (APRIL-SLE randomised trial).

Objectives: Despite advances in systemic lupus erythematosus (SLE) treatment, many patients suffer from the disease and side effects. Atacicept is a fusion protein that blocks B-lymphocyte stimulator and a proliferation-inducing ligand, which are increased in patients with SLE.

Methods: In this double-blind, placebo-controlled study, patients with moderate-to-severe SLE were randomised to atacicept 75 mg or atacicept 150 mg administered subcutaneously, or placebo twice-weekly for 4 weeks, then weekly for 48 weeks.

Interferon beta-1a for the maintenance of remission in patients with Crohn's disease: results of a phase II dose-finding study.

Background: Crohn's disease (CD) and multiple sclerosis (MS) share common pathogenic processes. Interferon (IFN) beta-1a is effective and generally well tolerated in patients with MS and has been shown to down-regulate the expression of interleukin-12, a cytokine that is thought to be involved in mucosal degeneration in CD. IFN beta-1a therefore offers promise as a treatment for CD.

Reduced B lymphocyte and immunoglobulin levels after atacicept treatment in patients with systemic lupus erythematosus: results of a multicenter, phase Ib, double-blind, placebo-controlled, dose-escalating trial.

Objective: To assess the safety and tolerability of atacicept in patients with systemic lupus erythematosus (SLE) and the biologic effect of atacicept on B lymphocyte and immunoglobulin levels. Atacicept is a TACI-Ig fusion protein that inhibits B cell stimulation by binding to B lymphocyte stimulator and a proliferation-inducing ligand.

Methods: This phase Ib, double-blind, placebo-controlled, dose-escalating trial comprised 6 cohorts of patients treated with atacicept or placebo in a 3:1 ratio of active drug to placebo (n = 8 per group; n = 7 in cohort 5).

Onercept for moderate-to-severe Crohn's disease: a randomized, double-blind, placebo-controlled trial.

Background And Aims: Onercept is a recombinant, soluble human p55 receptor to tumor necrosis factor-alpha.

Methods: A randomized, double-blind, placebo-controlled, dose-ranging trial was performed to evaluate the efficacy of onercept induction therapy in patients with Crohn's disease (CD). Patients (n = 207) with moderate-to-severe acute or chronic active CD were randomized to receive subcutaneous onercept (10, 25, 35, or 50 mg) or placebo 3 times weekly for 8 weeks.

CD134 plays a crucial role in the pathogenesis of EAE and is upregulated in the CNS of patients with multiple sclerosis.

We investigated the role of the CD134 (also named OX40) molecule in experimental allergic encephalomyelitis (EAE) and multiple sclerosis (MS). We examined the susceptibility of Cd134(-/-) mice to EAE, an autoimmune murine model that is dependent on infiltrating CD4+ T lymphocytes reactive to myelin proteins. EAE induced by myelin oligodendrocyte glycoprotein (MOG) injection in Cd134(-/-) mice showed less severe clinical signs of disease and markedly reduced inflammatory infiltrates within the central nervous system (CNS).

A homogeneous 384-well high-throughput binding assay for a TNF receptor using alphascreen technology.

To take advantage of the growing knowledge of cellular signaling pathways, modern-day drug discovery faces an increasing challenge to develop assays to screen for compounds that modulate protein-protein interactions. One bottleneck in achieving this goal is a lack of suitable and robust assay technologies amenable to a high-throughput format. In this report, we describe how we utilized Alphascreen trade mark technology to develop a high-throughput assay to monitor ligand binding to a member of the tumor necrosis factor receptor superfamily.
