Objective: Using the modified Rodnan skin score (mRSS) as a surrogate for disease activity, a phase 2a study in patients with systemic sclerosis (SSc) measured efficacy of the autotaxin inhibitor ziritaxestat. Mathematical modeling of mRSS was used to predict disease progression, examine candidate trial designs, and predict the probability of successfully discriminating treatment effect.

Methods: Patients with SSc receiving 600 mg of ziritaxestat or placebo for 24 weeks were included, in addition to data up to week 52 of the open-label extension (OLE).

Article Synopsis
  • The analysis looked at how filgotinib affects pain management in rheumatoid arthritis (RA) patients, based on data from the FINCH 1-3 studies.
  • Results showed that filgotinib started reducing pain by week 2, with sustained improvement observed throughout the studies.
  • In comparison to other treatments, filgotinib 200 mg led to better pain reduction and higher rates of patients achieving low pain levels and remission compared to filgotinib 100 mg and adalimumab.

Article Synopsis
  • The study assessed the effectiveness and safety of ziritaxestat, a medication targeting autotaxin, for treating early diffuse cutaneous systemic sclerosis (dcSSc) in a 24-week double-blind trial involving adults.
  • Results showed that patients taking ziritaxestat had a significantly greater decrease in skin thickness (measured by MRSS) compared to those on a placebo, and the medication was generally well tolerated, with headaches and diarrhea being the most common side effects.
  • Biomarker analysis indicated reductions in certain blood markers associated with fibrosis, suggesting ziritaxestat may help improve skin conditions in dcSSc patients through the modulation of the autotaxin/LPA pathway.

Article Synopsis
  • The phase 2 MANTA and MANTA-RAy studies aim to evaluate the effects of filgotinib, a drug that inhibits Janus kinase 1, on semen quality in men with inflammatory diseases.
  • These studies involve men aged 21-65 with active inflammatory bowel disease and rheumatic diseases, ensuring participants have no prior reproductive health issues and meet specific semen quality benchmarks.
  • The studies include a randomized, double-blind trial over 13 weeks, focusing on changes in sperm concentration and continued monitoring for those experiencing significant decreases, thus contributing to understanding the drug's overall impact.

This therapeutic protein-drug interaction study evaluated the disease-mediated effect of sirukumab (anti-interleukin 6 [anti-IL-6] monoclonal antibody) on the pharmacokinetics of the cytochrome P450 (CYP) probe substrates midazolam (CYP3A), omeprazole (CYP2C19), warfarin (CYP2C9), and caffeine (CYP1A2) in patients with active rheumatoid arthritis (RA). Twelve patients with C-reactive protein (CRP) ≥ 8.0 mg/L at screening received oral administration of a CYP probe cocktail consisting of 0.

Siltuximab, a monoclonal antibody (mAb) against interleukin (IL-6), is under development by Janssen Research & Development, LLC. During early clinical development, siltuximab was produced in a murine Sp2/0 myeloma cell line. The production cell line was switched to stably transfected Chinese hamster ovary (CHO) cell line for subsequent clinical development.

Objective: We undertook a 2-part, phase I, double-blind, placebo-controlled study to evaluate the safety and pharmacokinetics of multiple intravenous infusions of sirukumab, a human anti-interleukin-6 monoclonal antibody, in patients with cutaneous lupus erythematosus (CLE) or systemic lupus erythematosus (SLE).

Methods: In part A, patients with histologically confirmed CLE were randomized to 4 infusions of placebo or 1, 4, or 10 mg/kg sirukumab every 2 weeks. In part B, SLE patients diagnosed according to American College of Rheumatology criteria with a score of 5-12 on the Safety of Estrogens in Lupus Erythematosus National Assessment version of the SLE Disease Activity Index were randomized to 4 infusions of placebo or 10 mg/kg sirukumab every 2 weeks.

This double-blind, placebo-controlled, randomized study is the first in healthy volunteers to describe the safety, tolerability, and pharmacokinetics of sublingual asenapine at therapeutic dosages. After a 2-day placebo run-in phase, healthy male volunteers received placebo or asenapine escalated to dosages of 3, 5, 10, or 15 mg bid. Another group received single doses (2 and 5 mg) 1 week apart.

Background: The pharmacokinetics of golimumab, a human monoclonal antibody that inhibits the activity of tumor necrosis factor α, after a single subcutaneous (SC) or intravenous (IV) administration have been previously studied.

Objectives: The purpose of this study was to assess the pharmacokinetics of golimumab after multiple SC or IV administrations in patients with active rheumatoid arthritis (RA). The effect of concomitant methotrexate (MTX) use on golimumab pharmacokinetics was evaluated.

Photosensitivity is an important and distinguishing sign in various subtypes of cutaneous lupus erythematosus (CLE); however, it remains poorly defined. The purpose of this study was to evaluate whether standardized photoprovocation is a reproducible method to assess photosensitivity in subjects with CLE. A total of 47 subjects with CLE (subacute cutaneous lupus erythematosus (SCLE), n=14; discoid lupus erythematosus (DLE), n=20; lupus erythematosus tumidus (LET), n=13) and 13 healthy volunteers underwent photoprovocation at seven European sites.
