Sutimlimab, sold under the brand name Enjaymo, is a medication used to treat cold agglutinin disease (CAD).[1] Specifically it is used to prevent the breakdown of red blood cells.[2] It is given by gradual injection into a vein.[1] People need to be vaccinated against encapsulated bacteria before it is started.[1]

Common side effects include respiratory tract infections, diarrhea, joint pain, and peripheral swelling.[1] Other side effects may include infections, infusion reactions, and autoimmune diseases.[1] It is a monoclonal antibody that attaches to and blocks C1s.[2]

Sutimlimab was approved for medical use in the United States and Europe in 2022.[1][2] In the United States it costs about 280,000 USD per year for someone who weights 40 to 75 kg.[3] It is not marketed in the United Kingdom.[3]

Medical uses

Sutimlimab is indicated to decrease the need for red blood cell transfusion due to hemolysis (red blood cell destruction) in adults with cold agglutinin disease (CAD).[1][4] It improves hemoglobin levels and decreases the need for blood transfusions in 73% of people compared to 15% with a placebo.[2]

Dosage

It is initially given once per week for two weeks and than every two weeks.[2] For those who weight 39 to 75 kg the dose is 6,500 mg and for those who weight more than 75 kg the dose is 7,500 mg.[1]

Side effects

The most common side effects include respiratory tract infection, viral infection, diarrhea, dyspepsia (indigestion), cough, arthralgia (joint stiffness), arthritis, and swelling in the lower legs and hands.[4]

Pharmacology

Mechanism of action

Sutimlimab targets the C1s enzyme and inhibits its enzymatic propagation of the classical complement pathway, thereby, preventing the formation of the C3-convertase enzyme.[5]

History

The effectiveness of sutimlimab was assessed in a study of 24 adults with cold agglutinin disease who had a blood transfusion within the past six months.[4] All participants received sutimlimab for up to six months and could choose to continue therapy in a second part of the trial.[4] Based on body weight, participants received either a 6.5g or 7.5g infusion of sutimlimab into their vein on day 0, day 7, and every 14 days through week 25.[4]

In total, 54% of participants responded to sutimlimab.[4] The response was defined in the study as an increase in hemoglobin (an indirect measurement of the amount of red blood cells that are not destroyed) of 2 g/dL or greater (or to 12 g/dL or greater), and no red blood cell transfusions after the first five weeks of treatment; and no other therapies for cold agglutinin disease as defined in the study.[4]

The application for sutimlimab received orphan drug,[4][6] breakthrough therapy,[4] and priority review designations.[4] It is being developed by Bioverativ, a Sanofi company.[7]

Society and culture

Legal status

On 15 September 2022, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Enjaymo, intended for the treatment of hemolytic anemia in adults with cold agglutinin disease (CAD).[8] The applicant for this medicinal product is Genzyme Europe BV.[8]
