Inhibition of FcRn with rozanolixizumab in adults with immune thrombocytopenia: Two randomised, double‐blind, placebo‐controlled phase 3 studies and their open‐label extension

Nichola Cooper, James B. Bussel, Maciej Kaźmierczak et al. · 2024 · British Journal of Haematology

Summary Primary immune thrombocytopenia (ITP) is an antiplatelet‐antibody‐mediated disorder with accelerated platelet clearance and decreased platelet production. Rozanolixizumab, a monoclonal IgG4 anti‐FcRn antibody, blocks IgG recycling and decreases IgG levels. We report efficacy and safety of rozanolixizumab in adults with persistent/chronic ITP in 24‐week phase 3 studies (TP0003; TP0006), and their 52‐week open‐label extension (OLE). Primary end‐point was durable clinically meaningful platelet response (DCMPR) of ≥50 × 10 9 /L for 8/12 weeks during Weeks 13–25 in the double‐blind studies.

Efficacy of the meningococcal vaccine against Neisseria gonorrhoeae: a randomised clinical trial (MenGO)

Caroline Thng, Sharareh Eskandari, Fengyi Jin et al. · 2026 · npj Vaccines

Neisseria gonorrhoeae (NG) causes significant morbidity globally, and no licensed vaccine currently exists. Observational studies suggest the four-component meningococcal B (4CMenB) vaccine may provide cross-protection against NG. We conducted MenGO, an open-label, randomized controlled trial to evaluate the efficacy, safety, and immunogenicity of 4CMenB against NG in gay and bisexual men (GBM). Participants were randomized 1:1 to receive two doses of 4CMenB, or no vaccine, and were followed for 2 years with 3-monthly visits. 4CMenB vaccination did not significantly reduce gonorrhoea incidence

Genome-wide association study of idiopathic pulmonary fibrosis susceptibility using clinically curated European ancestry datasets

Daniel Chin, Tamara Hernández-Beeftink, Lauren J. Donoghue et al. · 2026 · European Respiratory Journal

ABSTRACT Background Idiopathic pulmonary fibrosis (IPF) is a rare, incurable lung disease with a median survival of 3-5 years after diagnosis. Treatment options are limited. Genetic association studies can identify new genes involved in disease that might represent potential new drug targets, and it has been shown that drug targets with support from genetic studies are more likely to be successful in clinical development. Previous genome-wide association studies (GWAS) of IPF susceptibility have identified more than 20 signals implicating genes involved in multiple mechanisms, including telome

CAR T-Cell Targeting of Macrophage Colony-Stimulating Factor Receptor

Daniela Achkova, Richard Beatson, John Maher · 2022 · Cells

Macrophage colony-stimulating factor receptor (M-CSFR) is found in cells of the mononuclear phagocyte lineage and is aberrantly expressed in a range of tumours, in addition to tumour-associated macrophages. Consequently, a variety of cancer therapies directed against M-CSFR are under development. We set out to engineer chimeric antigen receptors (CARs) that employ the natural ligands of this receptor, namely M-CSF or interleukin (IL)-34, to achieve specificity for M-CSFR-expressing target cells. Both M-CSF and IL-34 bind to overlapping regions of M-CSFR, although affinity of IL-34 is significa
