Sutimlimab

Sutimlimab-jome is an immunoglobulin G (IgG), subclass 4 (IgG4) monoclonal antibody (mAb) that inhibits the classical complement pathway (CP) and specifically binds to complement protein component 1, s subcomponent (C1s), a serine protease which cleaves C4. Sutimlimab-jome does not inhibit the lectin and alternative pathways.

• ENJAYMO is contraindicated in patients with known hypersensitivity to sutimlimab-jome or any of the inactive ingredients [see Warnings and Precautions (5.2) and Adverse Reactions (6.1) ] .

Vaccinate against encapsulated bacteria at least two weeks prior to treatment. ( 2.1 ) Weight-based dosage weekly for two weeks then every two weeks: For patients weighing 39 kg to less than 75 kg: 6,500 mg by intravenous infusion. ( 2.2 ) For patients weighing 75 kg or more: 7,500 mg by intravenous infusion. ( 2.2 ) See Full Prescribing Information for important preparation and administration instructions. ( 2.2 , 2.3 ) 2.1 Recommended Vaccinations for Encapsulated Bacterial Infections Vaccinate patients against encapsulated bacteria, including Streptococcus pneumoniae and Neisseria meningitidis (serogroups A, C, W, Y and B), according to current Advisory Committee on Immunization Practices (ACIP) recommendations at least 2 weeks prior to initiation of ENJAYMO [see Warnings and Precautions (5.1) ]. If urgent ENJAYMO therapy is indicated in a patient who is not up to date with vaccines for Streptococcus pneumoniae and Neisseria meningitidis administer these vaccines as soon as possible. 2.2 Recommended Dosage Regimen The recommended dosage of ENJAYMO for patients with CAD is based on body weight. For patients weighing 39 kg to less than 75 kg, the recommended dose is 6,500 mg and for patients weighing 75 kg or more, the recommended dose is 7,500 mg. Administer ENJAYMO intravenously weekly for the first two weeks, with administration every two weeks thereafter. Administer ENJAYMO at the recommended dosage regimen time points, or within two days of these time points. If a dose is missed, administer as soon as possible; thereafter, resume dosing every two weeks.

Serious Infections: Ensure patients are vaccinated against encapsulated bacteria. Monitor patients for early signs and symptoms of infections. ( 5.1 ) Infusion-Related Reactions: Monitor patients for infusion-related reactions, interrupt if reaction occurs, and institute appropriate medical management as needed. ( 5.2 ) Risk of Autoimmune Disease: Monitor patients for signs and symptoms and manage medically. ( 5.3 ) Recurrent Hemolysis After ENJAYMO Discontinuation: Monitor patients for signs and symptoms of hemolysis if treatment with ENJAYMO is interrupted. ( 5.4 ) 5.1 Serious Infections Including Those Caused by Encapsulated Bacteria ENJAYMO, a proximal classical complement C1s inhibitor, increases a patient's susceptibility to serious infections including those caused by encapsulated bacteria e.g. Neisseria meningitidis (any serogroup, including non-groupable strains), Streptococcus pneumoniae , and Haemophilus influenzae type B. Life-threatening and fatal infections with encapsulated bacteria have occurred in both vaccinated and unvaccinated patients treated with complement inhibitors. Serious infections (bacterial and viral) were reported in 15% (10/66) of patients receiving ENJAYMO from the two phase 3 studies. These infections included urinary tract infection with sepsis, respiratory tract infection, pneumonia, otomastoiditis, and skin infections One patient (1.5%) died due to klebsiella pneumonia.

The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling: Serious Infections [see Warnings and Precautions (5.1) ] Infusion-Related Reactions [see Warnings and Precautions (5.2) ] Risk of Autoimmune Disease [see Warnings and Precautions (5.3) ] Recurrent Hemolysis After ENJAYMO Discontinuation [see Warnings and Precautions (5.4) ] Most common adverse reactions in the CADENZA study (Part A) (incidence ≥18%) are rhinitis, headache, hypertension, acrocyanosis, and Raynaud's phenomenon. The most common adverse reactions in the CARDINAL study (incidence ≥25%) are urinary tract infection, respiratory tract infection, bacterial infection, dizziness, fatigue, peripheral edema, arthralgia, cough, hypertension, and nausea.

The safety of ENJAYMO in patients with a confirmed diagnosis of CAD was evaluated in a placebo-controlled study (CADENZA) in Part A (n=42) followed by an open-label single-arm study in Part B (n=39) and an open-label single-arm study (CARDINAL) (n=24) [see Clinical Studies (14) ] .

8.1 Pregnancy Risk Summary There are no available data on ENJAYMO use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Human immunoglobulin G (IgG) antibodies are known to cross the placental barrier; therefore, sutimlimab-jome may be transmitted from the mother to the developing fetus. In animal reproduction studies, intravenous administration of sutimlimab-jome to pregnant monkeys during organogenesis at doses 2 to 3 times the maximum recommended human doses did not result in adverse effects on pregnancy or offspring development (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2%-4% and 15%-20%, respectively. Data Animal data Pregnant monkeys were administered sutimlimab-jome at doses of 60 and 180 mg/kg/dose via 30-minute intravenous infusion once-weekly from gestation Day 20 to parturition (approximately 21 doses) resulting in exposures 2 to 3 times the human exposures at the maximum recommended doses, based on area under the curve (AUC).

Metabolism

Following administration of the approved weight-based recommended dosages, the exposure of sutimlimab-jome increases proportionally over a dosage range of 60 mg/kg to 100 mg/kg by intravenous infusion (0.3 to 1.5 times the maximum approved recommended dosage based on 75 kg body weight). Steady state was achieved by Week 7 after starting sutimlimab-jome treatment, with an accumulation ratio of less than 2.
