Introduction: Small molecules and antibodies are being developed to lower amyloid beta (Aβ) peptides.

Methods: We describe MEDI1814, a fully human high-affinity monoclonal antibody selective for Aβ, the pathogenic self-aggregating species of Aβ.

Results: MEDI1814 reduces free Aβ without impacting Aβ in the cerebrospinal fluid of rats and cynomolgus monkeys after systemic administration.

Objectives: Preclinical studies have demonstrated involvement of p38 mitogen-activated protein kinase signaling pathways in the development of persistent pain after peripheral nerve injury. A double-blind, randomized, placebo-controlled study was undertaken to evaluate the analgesic efficacy of losmapimod (GW856553), a novel p38α/β inhibitor, in patients with chronic neuropathic pain due to lumbosacral radiculopathy.

Materials And Methods: A total of 144 patients with at least moderate baseline pain intensity (average daily score of ≥4 on an 11-point pain intensity numeric rating scale) were randomized to receive losmapimod, 7.

Background: Inhibitors of p38 mitogen-activated protein kinase are undergoing evaluation as a novel class of anti-rheumatic drugs, by virtue of their ability to suppress the production of pro-inflammatory cytokines. Emerging data suggests that they may also attenuate peripheral or central sensitization in neuropathic pain. A double-blind, placebo-controlled study was undertaken to evaluate the analgesic efficacy of losmapimod (GW856553), a novel p38α/β inhibitor, in subjects with neuropathic pain following traumatic peripheral nerve injury.

Aims: This paper describes findings from the first-in-human study for GSK1482160, an orally available allosteric P2X7 receptor modulator. The study aimed to assess the pharmacokinetics (PK), pharmacodynamics (PD), safety and tolerability of the compound in healthy subjects.

Methods: Escalating single doses of up to 1 g were administered to healthy subjects in a single-blind and placebo-controlled fashion.

Article Synopsis
  • - The study assessed the pharmacokinetics of a new drug, GSK269984A, in healthy volunteers after taking a tiny dose orally or through injection to gather data on how the drug behaves in the body.
  • - Blood samples were taken over 24 hours to measure drug concentration, revealing that the injection led to faster and higher drug levels compared to oral intake, with an estimated oral bioavailability of 95%.
  • - The findings indicate that microdosing can help identify promising drugs early in development, especially when previous animal studies don't accurately predict human responses.
