Objective
We assessed and compared immunologic differences and associations with clinical response to guselkumab, a fully human interleukin (IL)–23p19 subunit inhibitor, in participants with active psoriatic arthritis (PsA) who were biologic‐naive or had inadequate response to tumor necrosis factor inhibitors (TNFi‐IR).
Methods
Serum biomarker levels at baseline and after treatment with guselkumab...
Aims
Liquid biopsy (LBx)‐based next‐generation sequencing (NGS) of circulating tumour DNA (ctDNA) can facilitate molecular profiling of haematopoietic neoplasms (HNs), particularly when tissue‐based NGS is infeasible.
Methods and Results
We studied HN LBx samples tested with FoundationOne Liquid CDx, FoundationOne Liquid, or FoundationACT between July 2016 and March 2022. We identified 271 samples:...
