Chronic kidney disease (CKD) and gout commonly co-occur. Pegloticase lowers serum urate (SU) in uncontrolled gout patients but antidrug antibodies limit urate-lowering response and increase infusion reaction (IR) risk. Methotrexate (MTX) co-administration increases pegloticase response rate and mitigates IR risk but CKD limits MTX use.

Objective: Evaluate patient-reported outcomes after 6 months of on-label guselkumab use in patients with rheumatologist-diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry.

Methods: This analysis includes registry participants who initiated and persisted with on-label guselkumab (after US Food and Drug Administration approval for PsA; 100 mg at weeks 0, 4, and every 8 weeks) at their 6-month follow-up visit (On-Label Persisters). Among patients not meeting response criteria at baseline, responses at 6 months were determined for patient-reported outcomes, including patient-reported pain (0-100 mm visual analog scale), patient global assessment of arthritis + psoriasis (PtGA; 0-100 visual analog scale), and Health Assessment Questionnaire-Disability Index (HAQ-DI; 0-3).

Introduction: The aim of this work is to evaluate treatment persistence and clinical outcomes after 6 months of on-label guselkumab use in patients with rheumatologist-diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry.

Methods: Participants with PsA who initiated and persisted with on-label guselkumab use post-Food and Drug Administration (FDA) approval for active PsA (7/13/2020; subcutaneous 100 mg at weeks 0, 4, and every 8 weeks) at their 6-month follow-up visit (occurring through 3/31/2023) comprised the primary analysis population (On-Label Persisters). Hierarchical, multiplicity-controlled primary and secondary outcomes were mean (95% confidence interval) changes from baseline at 6 months in clinical Disease Activity Index for PsA (cDAPSA; primary), Physician Global Assessment (PGA) of arthritis and psoriasis (visual analog scale [VAS] 0-100), patient-reported pain (VAS 0-100), and percent body surface area with psoriasis (%BSA).

Background: Biologic therapies are often prescribed for patients with rheumatoid arthritis (RA) who have inadequate responses to or are intolerant of methotrexate (MTX) and patients with poor prognostic indicators. This post hoc analysis evaluated effectiveness and safety of intravenous golimumab + MTX vs golimumab without MTX in RA patients.

Methods: AWARE, a real-world, prospective and pragmatic, Phase 4 study, compared effectiveness and safety of golimumab and infliximab in biologic-naïve and biologic-experienced patients.

Objective: Patients with uncontrolled/refractory gout have heavy disease burden, but few treatment options. Pegloticase lowers serum urate (SU), but anti-drug antibodies can limit treatment efficacy. Evidence supports immunomodulator-pegloticase co-administration to increase sustained urate-lowering rates, but published cases are limited.

Purpose: Golimumab is approved to treat moderate-to-severe active rheumatoid arthritis when given intravenously at weeks 0 and 4, then every 8 weeks (Q8W) with concomitant methotrexate. These analyses assessed whether a shorter dosing interval could ameliorate diminished efficacy experienced by a small proportion of patients toward the end of the dosing interval.

Methods: Population pharmacokinetic and exposure-response modeling simulations were performed for intravenous golimumab 2 mg/kg at weeks 0 and 4, then Q8W or every 6 weeks (Q6W) through 1 year.

Purpose: For patients with rheumatoid arthritis (RA) who do not respond or lose response to anti-tumor necrosis factor (TNF) biologics, switching to a different anti-TNF can be an effective means to manage symptoms and disease progression. This study examined the utilization and effectiveness of intravenous golimumab within a real-world population of patients with RA switching directly from infliximab, a potent anti-TNF.

Methods: Patient charts (n = 113) were collected from five US-based rheumatology practices.

Several hundred strains of Bacillus thuringiensis (Bt), isolated in New Zealand from samples of soil and sheep fleece, were tested for toxicity to larvae of the blowfly Lucilia cuprina Wiedemann. Characterization of the Bt strains revealed that three of the more active strains produced Cry1Ba (an insecticidal protein present in Bt mother cell crystal inclusion) that was toxic to blowflies. These strains were evaluated for the ability to prevent experimentally induced fly strike in a bioassay by using first instars.

During sporulation, Bacillus sphaericus 2362 produces a parasporal crystalline protein which is toxic for the larvae of a number of mosquito species. Using the Escherichia coli cloning vector lambda gt11, in which gene products of the inserts may be fused to beta-galactosidase, we isolated 29 bacteriophages which produced peptides-reacting with antiserum to crystal protein. On the basis of restriction enzyme analyses of the recombinants and Ouchterlony immunodiffusion experiments with induced lysogens as a source of antigens, the recombinants were assigned to three groups, designated A, B, and C.
