Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
QAMZOVA is a monoclonal antibody targeting the interleukin-17 receptor A (IL-17RA), blocking the interaction with IL-17 cytokines and inhibiting downstream inflammatory signaling pathways involved in psoriatic disease.
Aducanumab is a human monoclonal antibody that selectively binds to aggregated soluble and insoluble forms of amyloid beta, thereby reducing amyloid plaque deposition in the brain.
Treatment of moderate to severe plaque psoriasis in adults,Treatment of active psoriatic arthritis in adults
Treatment of Alzheimer's disease (FDA approved for patients with mild cognitive impairment or mild dementia stage of disease)
25 mg orally once daily, increased to 50 mg once daily after 4 weeks if tolerated. Maximum 100 mg once daily.
10 mg/kg intravenous infusion over approximately one hour, once every four weeks. Dosing initiation requires a titration schedule: first three doses at 1 mg/kg, fourth dose at 3 mg/kg, fifth dose at 6 mg/kg, and subsequent doses at 10 mg/kg.
Terminal elimination half-life is 12-15 hours in healthy adults; may be prolonged in renal impairment (up to 30-40 hours in severe impairment).
Terminal elimination half-life is approximately 26 days (range 19–34 days), supporting monthly intravenous dosing. The long half-life reflects the slow clearance of Ig G1 monoclonal antibodies.
QAMZOVA is a monoclonal antibody degraded into small peptides and amino acids via catabolic pathways; not metabolized by cytochrome P450 enzymes.
Aducanumab is a monoclonal antibody; it is expected to be degraded into small peptides and amino acids via catabolic pathways, similar to endogenous Ig G. No specific cytochrome P450 enzymes are involved.
Renal excretion of unchanged drug accounts for approximately 70-80% of elimination; biliary/fecal elimination accounts for 15-20%.
ADUHELM is eliminated primarily via catabolism into small peptides and amino acids. No renal or biliary excretion of intact monoclonal antibody is expected. Clearance is via the reticuloendothelial system; approximately 97% is metabolized, with <3% excreted as intact antibody in urine.
92-97% bound primarily to serum albumin.
Approximately 99% bound, primarily to endogenous Ig G (via Fc Rn binding) and other plasma proteins; specific binding proteins include Fc Rn.
0.8-1.2 L/kg, indicating extensive tissue distribution.
Volume of distribution is approximately 6.8 L (central compartment), equivalent to plasma volume; does not distribute extensively into tissues due to large molecular size. In L/kg: ~0.1 L/kg for a 70 kg patient.
Oral: 60-70% (due to first-pass metabolism).
Intravenous administration results in 100% bioavailability. No subcutaneous or oral formulation is available; thus no bioavailability for other routes.
e GFR 30-89 m L/min: no adjustment; e GFR 15-29 m L/min: reduce dose to 25 mg once daily; e GFR <15 m L/min or dialysis: not recommended.
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) or end-stage renal disease.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose to 25 mg once daily; Child-Pugh C: use not recommended.
No dose adjustment required for mild hepatic impairment (Child-Pugh A). Not studied in moderate (Child-Pugh B) or severe (Child-Pugh C) hepatic impairment.
Weight ≥40 kg: same as adult; weight <40 kg: not established (safety and efficacy not studied).
Safety and efficacy have not been established in pediatric patients. No recommended dosing available.
Initiate at 25 mg once daily; titrate slowly; monitor renal function more frequently.
No specific dose adjustment recommended for elderly patients. Clinical studies included patients aged 65 years and older; no overall differences in safety or efficacy observed.
No FDA black box warning.
WARNING: AMYLOID-RELATED IMAGING ABNORMALITIES (ARIA). Aducanumab can cause ARIA, including ARIA-E (edema/effusion) and ARIA-H (hemorrhage/hemosiderin deposition), which can be serious and life-threatening. ARIA generally occurs within the first 8 doses. Monitoring with MRI is required prior to and during treatment.
Increased risk of infections, including upper respiratory tract infections and candidiasis,Hypersensitivity reactions including anaphylaxis,Risk of inflammatory bowel disease exacerbation
Amyloid-related imaging abnormalities (ARIA), including ARIA-E and ARIA-H,Hypersensitivity reactions including angioedema and urticaria,Risk of seizures (reported in clinical trials),Concomitant use of antithrombotic medications may increase risk of intracranial hemorrhage
Known hypersensitivity to QAMZOVA or any excipient,Active tuberculosis or other severe infections
Known hypersensitivity to aducanumab or any excipients of ADUHELM
No known food interactions. Grapefruit and other CYP3A4 inhibitors do not affect QAMZOVA as it is a monoclonal antibody not metabolized by cytochrome P450 enzymes.
No specific food interactions reported. Patients should maintain a balanced diet as part of overall health management. Avoid grapefruit juice if taking other medications metabolized by CYP3A4, though aducanumab is not metabolized by CYP enzymes.
QAMZOVA is contraindicated in pregnancy due to known teratogenicity. First trimester exposure is associated with major congenital malformations including neural tube defects, cardiovascular anomalies, and craniofacial defects. Second and third trimester exposure may cause fetal growth restriction, oligohydramnios, and renal impairment. Use effective contraception during treatment.
No adequate and well-controlled studies in pregnant women. Based on mechanism of action (anti-amyloid beta monoclonal antibody), potential for fetal harm is unknown. No animal reproductive studies available. Use only if benefit outweighs potential risk.
QAMZOVA is excreted in human milk; M/P ratio is 1.2. Potential for serious adverse reactions in nursing infants; advise women not to breastfeed during treatment and for at least 30 days after the last dose.
No data on presence in human milk, effects on breastfed infant, or effects on milk production. Aducanumab is a large Ig G molecule; likely excreted into milk in low amounts. M/P ratio unknown. Consider developmental and health benefits of breastfeeding along with mother's clinical need.
Pharmacokinetic changes in pregnancy (increased clearance, volume of distribution) may require dose adjustments. However, due to teratogenicity, QAMZOVA is contraindicated in pregnancy; no recommended dose adjustments. If accidental exposure occurs, discontinue immediately.
No pharmacokinetic data during pregnancy. Dose adjustments not established. Administer same dose as non-pregnant adults (10 mg/kg IV monthly after titration) unless significant infusion reactions occur.
QAMZOVA is a monoclonal antibody targeting IL-23; monitor for hypersensitivity reactions during infusion. Premedicate with antihistamines and acetaminophen for infusion reactions. Avoid live vaccines during treatment. Screening for latent TB required before initiation.
ADUHELM (aducanumab-avwa) is a monoclonal antibody targeting aggregated forms of beta-amyloid. It is indicated for Alzheimer disease. Confirmation of amyloid beta pathology via PET or CSF is required before initiation. Titration over 6-8 months is mandatory to reduce risk of amyloid-related imaging abnormalities (ARIA). Monitor for ARIA with MRI prior to the 7th and 12th infusions; suspend dosing if ARIA is detected. Adverse effects include ARIA-E (edema/effusion) and ARIA-H (hemosiderin deposition). Coadministration with anticoagulants may increase risk of ARIA-H. Assess for hypersensitivity reactions. No specific reversal agent is available.
Inform your healthcare provider if you have any infections or signs of infection such as fever, chills, or cough.,Avoid receiving live vaccines while taking QAMZOVA.,Report any symptoms of allergic reactions, including rash, itching, or difficulty breathing, especially during or after infusion.,Notify your doctor if you are pregnant, planning to become pregnant, or breastfeeding.,Keep all appointments for infusion therapy and lab work as scheduled.
