Anaemia icon

CAD is a rare, chronic, autoimmune haemolytic anaemia that shouldn’t be confused with cold agglutinin syndrome (CAS) secondary to infection or cancer1,4

C1 activation icon

In CAD, activated C1 triggers the classical complement pathway and drives chronic haemolysis4  

Risk icon

Patients can face risks for severe anaemia and possible life-threatening TEs despite current management3,5

Fatigue icon

Profound fatigue and life-limiting burden persist despite current management6-10 

Clipboard icon

There are specific criteria to diagnose CAD

Future goals icon

See the goals for future CAD treatment

Sanofi is committed to ongoing CAD research.

CAD=Cold Agglutinin Disease; CAS=cold agglutinin syndrome; TE=thromboembolic event.
