Inhibits P2Y12 platelet receptor, blocking ADP-mediated platelet aggregation.
BIMZELX (bimekizumab) is a humanized monoclonal Ig G1 antibody that selectively neutralizes interleukin-17A (IL-17A) and interleukin-17F (IL-17F), inhibiting their binding to the IL-17 receptor and subsequent pro-inflammatory signaling.

1 drop of 0.45% solution in each eye once daily in the evening or as directed by physician.
Subcutaneous injection: 160 mg (two 80 mg injections) at week 0, week 2, week 4, then every 4 weeks.
Terminal elimination half-life: approximately 2-3 hours in aqueous humor; systemic half-life is negligible due to low plasma concentrations.
Terminal elimination half-life is approximately 26 days (range 22–29 days) across approved doses; supports every 4-week subcutaneous dosing.
Prodrug; metabolized to active metabolite primarily via CYP2C19, with contributions from CYP3A4, CYP2C9, CYP2B6
Bimekizumab is likely degraded into small peptides and amino acids via general protein catabolism. It is not metabolized by CYP450 enzymes.
Renal excretion of unchanged drug accounts for approximately 1-2% of an administered dose; the remainder is metabolized in ocular tissues and eliminated via nasolacrimal drainage and gastrointestinal tract, with minimal systemic absorption. Biliary/fecal excretion is negligible.
Bimekizumab is a monoclonal antibody that is degraded into small peptides and amino acids via general protein catabolism; no renal or biliary excretion of intact antibody. Fecal excretion of degraded fragments is minor (<1%).
Approximately 60-70% bound to plasma proteins, primarily albumin.
Approximately 99% bound to target (IL-17A and IL-17F) in serum; albumin binding is negligible.
Due to minimal systemic absorption, volume of distribution data is not clinically relevant; for the fraction absorbed, estimated Vd is approximately 0.2-0.4 L/kg.
Volume of distribution at steady state is approximately 7.0 L (0.1 L/kg assuming 70 kg), indicating limited extravascular distribution, consistent with a monoclonal antibody primarily in plasma and interstitial fluid.
Ocular instillation: systemic bioavailability is low (<1%) due to extensive first-pass metabolism in the nasal mucosa and gastrointestinal tract after nasolacrimal drainage.
Subcutaneous: Approximately 80% (range 60–100%) compared to intravenous administration.
No specific renal dose adjustments recommended; use with caution in severe renal impairment (Cr Cl <30 m L/min) due to potential systemic accumulation.
No dose adjustment required for mild to moderate renal impairment. Not studied in severe renal impairment (e GFR <30 m L/min/1.73 m2).
No specific hepatic dose adjustments recommended; use with caution in severe hepatic impairment (Child-Pugh Class C) due to lack of data.
No dose adjustment required for mild to moderate hepatic impairment (Child-Pugh A or B). Not studied in severe hepatic impairment (Child-Pugh C).
Safety and effectiveness in pediatric patients have not been established; use is not recommended.
Safety and efficacy not established in pediatric patients.
No specific dose adjustments in elderly; use same as adult dosing, with monitoring for ocular adverse effects.
No specific dose adjustment recommended; pharmacokinetics similar to younger adults in clinical studies with patients up to 75 years.
Efficacy depends on active metabolite formation; reduced efficacy in CYP2C19 poor metabolizers. Avoid use in patients with active pathological bleeding or history of transient ischemic attack/stroke.
None.
Bleeding risk, especially in patients undergoing surgery; thrombotic thrombocytopenic purpura (TTP) reported; premature discontinuation increases cardiovascular event risk; CYP2C19 poor metabolizers may have reduced efficacy.
Increased risk of infections, including serious infections; avoid use during active infection,Hypersensitivity reactions including urticaria and angioedema,Exacerbation of inflammatory bowel disease (Crohn's disease or ulcerative colitis),Potential for increased suicidality or depression; monitor for neuropsychiatric symptoms,Avoid live vaccines during treatment,Tuberculosis screening prior to initiation
Active pathological bleeding (e.g., peptic ulcer, intracranial hemorrhage); history of transient ischemic attack or stroke; severe hepatic impairment; hypersensitivity to AKPRO or any component.
Known hypersensitivity to bimekizumab or any excipient,Active tuberculosis or other severe infections
No known food interactions.
There are no known food interactions with BIMZELX. Take with or without food.
Category C. First trimester: Based on animal studies, may cause fetal harm. No adequate human studies. Second and third trimesters: Risk of premature closure of ductus arteriosus and oligohydramnios with NSAID use after 20 weeks gestation.
Bimekizumab is a humanized monoclonal Ig G1 antibody that inhibits IL-17A and IL-17F. As a large protein, it is transported across the placenta via Fc Rn-mediated transfer, with fetal levels increasing during the second and third trimesters. Available data are insufficient to determine a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Animal studies showed no evidence of teratogenicity or fetal harm in monkeys at doses up to 100 mg/kg (approximately 30 times the human exposure at the recommended dose). However, monoclonal antibodies are known to cross the placenta, and the theoretical risk of fetal immune suppression exists. Therefore, bimekizumab should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Excreted in breast milk in low amounts (M/P ratio not reported). Use with caution due to potential adverse effects on infant (e.g., gastrointestinal, renal). Short-term use is generally considered acceptable.
It is unknown whether bimekizumab is excreted in human milk or absorbed systemically after ingestion. Monoclonal antibodies are generally present in breast milk at very low concentrations with limited oral bioavailability due to protein digestion in the infant's gastrointestinal tract. The M/P ratio has not been determined. Due to the potential for adverse reactions in the breastfed infant, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
No specific dose adjustment recommended for pregnancy; however, avoid use after 20 weeks gestation due to risks of premature ductus arteriosus closure and oligohydramnios. Use lowest effective dose for shortest duration.
No dose adjustment is recommended during pregnancy based on pharmacokinetic changes. Bimekizumab clearance is not expected to be significantly altered by pregnancy-related physiological changes. However, given the limited data, the drug should be used only if clearly needed. Monitor clinical response and adjust dose if necessary (though no standard guidelines exist).
AKPRO is a combination ophthalmic solution containing proparacaine 0.5% and fluorescein sodium 0.25%. Use only for diagnostic procedures; never dispense for patient self-administration due to risk of corneal toxicity with repeated use. Apply one drop per eye, then wait 1-2 minutes for maximal anesthesia. Blot excess to reduce systemic absorption. Monitor for corneal epithelial defects after use.
BIMZELX (bimekizumab) is a humanized monoclonal Ig G1 antibody that selectively inhibits both IL-17A and IL-17F. It is administered subcutaneously with a loading dose at weeks 0, 2, 4, then every 8 weeks. Monitor for exacerbations of inflammatory bowel disease (Crohn's or ulcerative colitis) as IL-17 inhibition can rarely trigger or worsen these conditions. Do not administer live vaccines during treatment. Consider tuberculosis screening prior to initiation.

You may be at increased risk of infections, including upper respiratory tract infections and oral candidiasis. Report any signs of infection to your healthcare provider promptly.,If you have a history of inflammatory bowel disease (Crohn's disease or ulcerative colitis), tell your doctor before starting treatment, as this medicine can worsen it.,Do not receive live vaccines while on BIMZELX. Discuss any required vaccinations with your doctor before starting therapy.,This medication is given as an injection under the skin. You or your caregiver can be trained to administer it at home. Rotate injection sites and do not inject into tender, bruised, or scarred skin.,Store BIMZELX in the refrigerator at 2°C to 8°C (36°F to 46°F). Do not freeze. Protect from light.
