Overview
Sutimlimab-jome is an immunoglobulin G (IgG) subclass 4 (IgG4) monoclonal antibody that binds to complement protein component 1, s subcomponent (C1s).
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 does not inhibit the lectin and alternative pathways. Inhibition of the classical complement pathway at the level of C1s prevents deposition of complement opsonins on the surface of red blood cells, resulting in inhibition of hemolysis in patients with cold agglutinin disease (CAD).
Greater than 90% inhibition of CP was observed following a single sutimlimab infusion and was sustained in patients with CAD when sutimlimab concentrations were >=100 mcg/mL. C4 levels returned to normal (0.2 g/L) within 1 week following the first dose of sutimlimab. Complete CP inhibition following initiation of sutimlimab treatment led to inhibition of hemolysis as evidenced by normalization of bilirubin, decrease in lactate dehydrogenase, increase in haptoglobin, and decrease in reticulocytes.
After the first treatment with sutimlimab, near normalization of bilirubin associated with a >1 g/dL increase in hemoglobin was observed, demonstrating the effect of CP inhibition. The extent and duration of the pharmacodynamic response in patients with CAD were exposure dependent for sutimlimab.
Following administration of the approved weight-based recommended dosages, the exposure of sutimlimab increases proportionally over a dosage range of 60-100 mg/kg by IV infusion. Steady state was achieved by week 7 after initiating sutimlimab treatment.
The terminal elimination half-life and clearance of sutimlimab varies at different doses due to target-mediated drug disposition at lower concentrations. The terminal elimination half-life of sutimlimab is 21 days at the approved recommended dosage. As a protein antibody, sutimlimab is expected to be metabolized by degradation into small peptides and individual amino acids.
No clinically significant differences in the pharmacokinetics of sutimlimab were observed based on sex, age (19-88 years of age), ethnicity (Japanese, non-Japanese), and mild to moderate renal impairment (30-89 mL/minute per 1.73 m2 measured by estimated glomerular filtration rate (eGFR)). The effects of severe renal impairment and hepatic impairment on the pharmacokinetics of sutimlimab are unknown. Population pharmacokinetic analysis shows that sutimlimab exposures decreased up to 59% for a patient weighing 98 kg and increased up to 57% for a patient weighing 50.5 kg as compared with a patient weighing 72 kg.
The effect of body weight on pharmacokinetics has been integrated in the recommended dose regimen tiered by body weight.
USES: Sutimlimab is used to treat a certain rare blood disorder (cold agglutinin disease). This disease causes your body's immune system to break down red blood cells, which results in anemia. Sutimlimab works by helping to block the body's breakdown of red blood cells.
This effect helps lessen symptoms of anemia (such as tiredness) and may reduce the need for blood transfusions.

Also known as: Reduction Of Blood Transfusions In Cad, Reduction Of Blood Transfusions In Cold Autoimmune Hemolytic Anemia, Reduction Of Blood Transfusions In Cold Hemagglutinin Disease.
Dosing
No dosing information is available for this tab.
Administer by IV infusion only. Sutimlimab may be administered as a diluted or undiluted preparation.
Store unopened sutimlimab-jome vials in the refrigerator at 2-8degreesC in the original carton; protect from light. Do not freeze or shake.
Prior to use, remove the drug from the refrigerator and do not shake to minimize foaming. Inspect vials and parenteral drug product visually for particulate matter and discoloration prior to administration. Sutimlimab is a clear to slightly opalescent and colorless to slightly yellow solution.
If using a diluted preparation, withdraw the calculated volume from the appropriate number of vials based on the recommended dosage and dilute the calculated volume with 0.9% sodium chloride injection to a total volume of 500 mL (see Table 1).
If using an undiluted preparation, withdraw the calculated volume from the appropriate number of vials based on the recommended dosage and add to an empty infusion bag (see Table 2).
If the infusion solution is not used immediately, store under refrigeration at 2-8degreesC. Once removed from refrigeration, allow the infusion solution to adjust to room temperature (20-25degreesC) and administer within 8 hours. Total time from the time of preparation, including refrigeration, adjustment to room temperature, and the expected infusion time should not exceed 36 hours. In-line infusion warmers may be used, but should not exceed a temperature of 40degreesC.
Administer sutimlimab infusion solution only through a 0.2 micron in-line filter with a polyethersulfone (PES) membrane. Prime the infusion catheter and/or tubing with the dosing solution immediately before infusion and flush immediately following completion of the infusion with a sufficient quantity (approximately 20 mL) of 0.9% sodium chloride injection.

Safety and effectiveness in pediatric patients have not been established.
There are no available data on sutimlimab use in pregnant patients 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 may be transmitted from the mother to the developing fetus. Animal studies in monkeys at doses 2-3 times the maximum recommended human dose did not indicate adverse effects on pregnancy or offspring development.
No effects on reproductive and developmental parameters were observed in maternal animals and offspring, respectively.
There are no data on the presence of sutimlimab in human milk, effects on the breastfed child, or the effects on milk production. Maternal IgG is known to be present in human milk. The effects of local GI exposure and limited systemic exposure in the breastfed child to sutimlimab are unknown. No conclusions can be drawn regarding whether or not sutimlimab is safe for use during breastfeeding. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for sutimlimab and any potential adverse effects on the breastfed child from sutimlimab or from the underlying maternal condition.
The manufacturer makes no specific dosage recommendations for geriatric patients.
Of the 66 patients with cold agglutinin disease in clinical studies of sutimlimab, 65% were 65 years of age and over including 27% who were 75 years of age and over. No overall differences in safety or effectiveness were observed between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients; however, greater sensitivity of some older individuals cannot be ruled out.
