Integrated Clinical and Proteomic Profiling of CD19 Chimeric Antigen Receptor T Cell Therapy in Progressive Systemic Sclerosis

Arthritis RheumatolPublished Prospective single-group study with longitudinal proteomic profiling

Authors' conclusion

Relma-cel therapy in patients with SSc led to early clinical improvement, supported by CAR-T cell expansion, B cell depletion, and a favorable safety profile. Proteomic alterations were associated with the observed clinical improvements and suggested broad remodeling of inflammatory and fibrotic pathways.

Study context

Population
Patients with progressive systemic sclerosis (SSc)
Methodological detailsSomaScan plasma proteomics
  • SomaScan plasma proteomics

Main finding

As reported in the abstract

  • Sustained clinical improvement across multiple SSc domains, incl. skin involvement and patient- and physician-assessed disease activity
  • Rapid B cell depletion followed by immune reconstitution
  • Coordinated longitudinal changes in proteins and pathways of inflammation, fibrosis, vascular remodeling and immune regulation
  • Day 180: down-regulation of profibrotic/inflammatory proteins and up-regulation of proteins potentially linked to vascular repair or immune regulation
  • Pathway analyses: broad attenuation of inflammatory and fibrotic programs with relative enhancement of repair-associated processes

Observational data: associations, not effects.
