Extrapolation of the Efficacy and Pharmacokinetics of Belimumab to Support its Use in Children with Lupus Nephritis.

Background And Objective: Lupus nephritis (LN), a severe manifestation of systemic lupus erythematosus, has greater severity in children versus adults. Belimumab is approved for systemic lupus erythematosus treatment in patients aged ≥ 5 years, and for active LN in adults in the European Union, China, Japan and Latin America, and patients aged ≥ 5 years in the USA. Low prevalence of paediatric active LN makes conducting a clinical study within a reasonable period unfeasible.

Effect of belimumab on kidney-related outcomes in patients with lupus nephritis: post hoc subgroup analyses of the phase 3 BLISS-LN trial.

Background: Data on belimumab efficacy in patients with lupus nephritis (LN) according to diagnosis duration or induction therapy are limited. Post hoc analyses of the phase 3, randomized, double-blind BLISS-LN study (GSK BEL114054; NCT01639339) were performed to assess belimumab efficacy on kidney-related outcomes in newly diagnosed and relapsed LN subgroups and according to the use of glucocorticoid (GC) pulses at induction.

Methods: BLISS-LN randomized 448 patients with active LN to monthly intravenous belimumab 10 mg/kg or placebo plus standard therapy.

Safety and efficacy of belimumab in older adults with SLE: results of an integrated analysis of clinical trial data.

Objective: Assess the safety and efficacy of belimumab in older adults with SLE.

Methods: This post hoc integrated analysis (GSK Study 116559) included safety data from six randomised, placebo-controlled belimumab trials (BLISS-76, BLISS-52, BLISS-SC, North East Asia study, LBSL02, EMBRACE; n=4170). The BASE study provided additional safety data (n=4003).

Safety and Efficacy of Belimumab in Patients with Lupus Nephritis: Open-Label Extension of BLISS-LN Study.

Background And Objectives: In the BLISS-LN study, belimumab improved kidney outcomes in adult patients with active lupus nephritis. This 28-week open-label extension of BLISS-LN assessed belimumab's safety and efficacy.

Design, Setting, Participants, & Measurements: Eligible patients completing BLISS-LN received monthly intravenous belimumab 10 mg/kg plus standard therapy.

Efficacy and Safety of Belimumab in Patients With Lupus Nephritis: Subgroup Analyses of a Phase 3 Randomized Trial in the East Asian Population.

Rationale & Objective: Belimumab improved kidney outcomes in patients with active lupus nephritis (LN) in BLISS-LN, leading to its approval in the United States and the European Union. As data on treatment of East Asian patients with LN are limited, we evaluated the efficacy and safety of belimumab in the BLISS-LN East Asian subgroup.

Study Design: Prespecified subgroup analysis of BLISS-LN, a phase 3, placebo-controlled, randomized 104-week trial.

Renal response at 2 years post biopsy to predict long-term renal survival in lupus nephritis: a retrospective analysis of the Hopkins Lupus Cohort.

Objective: This retrospective analysis evaluated the prognostic value of renal response status 2 years after biopsy-proven lupus nephritis (LN) for the prediction of long-term renal outcomes.

Methods: Eligible patients with SLE as per American College of Rheumatology or Systemic Lupus International Collaborating Clinics criteria and biopsy-proven class III, IV, V or mixed LN were identified from the Hopkins Lupus Cohort, and categorised into binary renal response categories (modified primary efficacy renal response (mPERR) or no mPERR at 2 years post biopsy). These categories were defined by a modified version of the Belimumab International Lupus Nephritis Study (BLISS-LN) protocol using urine protein:creatinine ratio (≤0.

A secondary analysis of the Belimumab International Study in Lupus Nephritis trial examined effects of belimumab on kidney outcomes and preservation of kidney function in patients with lupus nephritis.

We performed a post hoc analysis of the Belimumab International Study in Lupus Nephritis (BLISS-LN), a Phase 3, multinational, double-blind, 104-week trial, in which 448 patients with lupus nephritis were randomized to receive intravenous belimumab 10 mg/kg or placebo with standard therapy (cyclophosphamide/azathioprine or mycophenolate mofetil). Add-on belimumab was found to be most effective in improving the primary efficacy kidney response and complete kidney response in patients with proliferative lupus nephritis and a baseline urine protein/creatinine ratio under 3 g/g. However, there was no observed improvement in the kidney response with belimumab treatment in patients with lupus nephritis and sub-epithelial deposits or with a baseline protein/creatinine ratio of 3 g/g or more.

Two-Year, Randomized, Controlled Trial of Belimumab in Lupus Nephritis.

Background: In adults with active lupus nephritis, the efficacy and safety of intravenous belimumab as compared with placebo, when added to standard therapy (mycophenolate mofetil or cyclophosphamide-azathioprine), are unknown.

Methods: In a phase 3, multinational, multicenter, randomized, double-blind, placebo-controlled, 104-week trial conducted at 107 sites in 21 countries, we assigned adults with biopsy-proven, active lupus nephritis in a 1:1 ratio to receive intravenous belimumab (at a dose of 10 mg per kilogram of body weight) or matching placebo, in addition to standard therapy. The primary end point at week 104 was a primary efficacy renal response (a ratio of urinary protein to creatinine of ≤0.

Efficacy and Safety of Belimumab and Azathioprine for Maintenance of Remission in Antineutrophil Cytoplasmic Antibody-Associated Vasculitis: A Randomized Controlled Study.

Objective: To evaluate the safety and efficacy of belimumab as adjunctive therapy to maintain remission in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).

Methods: In this multicenter, double-blind, placebo-controlled study, patients with AAV (ages ≥18 years) were randomized 1:1 to receive azathioprine (2 mg/kg/day), low-dose oral glucocorticoids (≤10 mg/day), and either intravenous belimumab (10 mg/kg) or placebo, following remission induction with rituximab or cyclophosphamide along with glucocorticoids. The primary end point was time to first protocol-specified event (PSE), with first PSE defined as a Birmingham Vasculitis Activity Score (BVAS) of ≥6, presence of ≥1 major BVAS item, or receipt of prohibited medications for any reason, resulting in treatment failure (adjusted for ANCA type [proteinase 3 (PR3) or myeloperoxidase (MPO)], disease stage at induction, and induction regimen).

Safety, pharmacokinetics, and pharmacodynamics of ivacaftor in patients aged 2-5 years with cystic fibrosis and a CFTR gating mutation (KIWI): an open-label, single-arm study.

Background: Ivacaftor has been shown to be a safe, effective treatment for cystic fibrosis in patients aged 6 years or older with a CFTR gating mutation. We aimed to assess the safety, pharmacokinetics, and pharmacodynamics of ivacaftor in children aged 2-5 years.

Methods: In the two-part KIWI study, we enrolled children aged 2-5 years weighing 8 kg or more with a confirmed diagnosis of cystic fibrosis and a CFTR gating mutation on at least one allele from 15 hospitals in the USA, UK, and Canada.

Dual bronchodilation with QVA149 versus single bronchodilator therapy: the SHINE study.

We investigated the efficacy and safety of dual bronchodilation with QVA149 versus its monocomponents indacaterol and glycopyrronium, tiotropium and placebo in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). This was a multicentre, randomised, double-blind, placebo- and active-controlled, 26-week trial. Patients (n = 2144) were randomised (2:2:2:2:1) to receive once-daily QVA149 (indacaterol 110 μg/glycopyrronium 50 μg), indacaterol 150 μg, glycopyrronium 50 μg, open-label tiotropium 18 μg or placebo.
