CareDx Study Links dd-cfDNA Elevations to Long-Term Kidney Transplant Outcomes

  • CareDx published a KOAR study in JASN showing dd-cfDNA elevations predict kidney allograft outcomes.
  • Analysis of 1,258 patients found a 3.7x and 6.4x higher risk of allograft loss for intermediate and high dd-cfDNA states.
  • 36% of patients experienced dd-cfDNA elevation while kidney function remained preserved.
  • Persistently low dd-cfDNA levels correlated with favorable long-term outcomes.

This study strengthens CareDx's position in precision medicine for transplant monitoring, particularly as payers increasingly demand evidence of long-term clinical utility. The findings support dd-cfDNA's role in early intervention, aligning with broader trends toward proactive transplant management. CareDx's ability to commercialize this data will depend on demonstrating cost-effectiveness in real-world settings.
