Nearly 20% of people with autoimmune hemolytic anemia (AIHA), including cold agglutinin disease (CAD), who required blood transfusions developed antibodies against proteins in donor blood that could compromise a transfusion’s safety or effectiveness, a study shows. These antibodies, called alloantibodies, were associated with a higher transfusion burden, lower…

Treatment with rituximab led to improvements in biomarkers of red blood cell destruction among people with cold agglutinin disease (CAD), but the  improvements often were short-lived and reversible, according to a real-world analysis in the U.S. The therapy, which often is used off-label for the rare autoimmune disease, also…

A free symposium on complement cascade-targeted treatment approaches for cold agglutinin disease (CAD) will be held live and virtually today ahead of the 2023 American Society of Hematology (ASH) meeting taking place in San Diego, California, Dec. 9-12. Announced in a tweet earlier this week, the session titled…

Among people with cold agglutinin disease (CAD), more than half were found to have a related autoimmune disorder called cryoglobulinemia, which affected symptom presentation but did not appear to affect survival. That’s according to a small study in which 59% of CAD patients tested positive for cryoglobulins, the…

Long-term treatment with Enjaymo (sutimlimab-jome) led to sustained improvements in life quality and reductions in fatigue for people with cold agglutinin disease (CAD), according to 2.5 years of data from the Phase 3 CARDINAL clinical trial. “[Enjaymo] provides sustained and durable treatment benefits in chronic CAD, including a…

A woman with a mixed form of autoimmune hemolytic anemia (AIHA), who was having only temporary responses to standard treatment, experienced complete disease remission after being given an interleukin-23 (IL-23) inhibitor for a separate condition, a case study shows. IL-23 inhibitor therapies are used for other inflammatory diseases, but have…

Researchers have developed a new patient-reported outcome questionnaire to assess symptoms and the impacts to daily life associated with cold agglutinin disease (CAD). Called the CAD-Symptoms and Impact Questionnaire (CAD-SIQ), it was developed by analyzing responses from patient interviews. Reactions to cold environments and fatigue were the most commonly…

Dianthus Therapeutics plans to launch a proof-of-concept clinical trial of its therapy candidate DNTH103 in 2024 to test the efficacy of the complement inhibitor in people with cold agglutinin disease (CAD). Data from the trial would be expected in the second half of next year. Funding for the…

Among people who meet the criteria for a blood condition called IgM monoclonal gammopathy of undetermined significance (IgM-MGUS), those with cold agglutinin disease (CAD) show distinct clinical and laboratory features from those without, a study shows. IgM-MGUS is marked by the excessive production of immunoglobulin M (IgM), a type…

A treatment to reduce the activation of the immune complement system didn’t increase the effectiveness of red blood cell transfusions in people with severe cold agglutinin disease (CAD) and other complement-mediated autoimmune hemolytic anemia (CM-AIHA). That’s according to a small, proof-of-concept Phase 2 clinical trial (EudraCT2012-003710-13) that found…
