Notes

  • CAR T-cell therapy is being adapted to target solid tumours, specifically rare types like alveolar soft-part sarcoma (ASPS) and certain kidney cancers.
  • Researchers identified the protein GPNMB as a consistent target expressed on the surface of these solid tumour cells.
  • Clinical observation showed that the therapy led to disease stabilisation for three months in an advanced ASPS patient, with the disappearance of several smaller tumours.
  • The therapy was reported to be well-tolerated by the patient.
  • Combining CAR T-cell therapy with immune checkpoint blockers is proposed as a strategy to overcome treatment resistance.
