Dosing & Uses
Dosage Forms & Strengths
solution for SC injection
- 210mg/1.5mL (single-dose prefilled syringe)
Indicated for moderate-to-severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy and have failed to respond or have lost response to other systemic therapies

210 mg SC q2wk
If an adequate response has not been achieved after 12-16 weeks, consider discontinuing therapy; continued treatment beyond 16 weeks in patients who have not achieved an adequate response is not likely to result in greater success
Evaluate patients for tuberculosis (TB) prior to initiating (see Cautions)
Safety and efficacy not established
Serious - Use Alternative
Significant - Monitor Closely
Fungal infections (2.4%)
Injection site reaction (1.3%)
Oropharyngeal pain (1.1%)

Tinea infections (0.2%)
Black Box Warnings
Suicidal ideation and behavior, including completed suicides, have occurred in patients treated with brodalumab
Prior to prescribing, weigh the potential risks and benefits in patients with a history of depression and/or suicidal ideation or behavior
Patients with new or worsening suicidal ideation and behavior should be referred to a mental health professional, as appropriate
Advise patients and caregivers to seek medical attention for manifestations of suicidal ideation or behavior, new-onset or worsening depression, anxiety, or other mood changes
Because of the observed suicidal behavior, brodalumab is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the SILIQ REMS Program
Patient wallet card
- Give patients the Patient Wallet Card and instruct them to carry it with them at all times
- Patients should seek medical evaluation and show the card, to the treating healthcare provider, if they experience symptoms of suicide or depression described on the card
- They should also call the National Suicide Prevention Lifeline at 1-800-273-8255 if they experience suicidal thoughts
Suicidal ideation and behavior, including 4 completed suicides, occurred in subjects treated in the psoriasis clinical trials; there were no completed suicides in the 12-week placebo-controlled portion of the trials; brodalumab users with a history of suicidality or depression had an increased incidence of suicidal ideation and behavior as compared with users without such a history (see Black Box Warnings)
Available only through a restricted access program (see Black Box Warnings)
May increase risk of infections; in patients with a chronic infection or a history of recurrent infection, consider the risks and benefits prior to prescribing; if a patient develops a serious infection or is not responding to standard therapy for the infection, monitor the patient closely and discontinue the drug until the infection resolves
Evaluate patients for TB before initiating; do not administer to patients with active TB; initiate treatment for latent TB prior to administering brodalumab; closely monitor patients for signs and symptoms of active TB during and after treatment
In psoriasis trials, which excluded subjects with active Crohn disease, Crohn disease occurred in 1 subject during treatment and led to brodalumab discontinuation; in other trials, exacerbation of Crohn disease was observed with brodalumab (see Contraindications)
Drug interaction overview
- Avoid use of live vaccines; no data are available on the ability of live or inactive vaccines to elicit an immune response in patients being treated with brodalumab
- CYP450 substrates
- The formation of CYP450 enzymes can be altered by increased levels of certain cytokines (eg, IL-1, IL-6, IL-10, TNF-alpha, IFN) during chronic inflammation
- Brodalumab may modulate serum levels of some cytokines
- Therefore, upon initiating or discontinuing brodalumab in patients who are receiving concomitant drugs that are CYP450 substrates, particularly those with a narrow therapeutic index, consider monitoring for effect (eg, for warfarin) or drug concentration (eg, for cyclosporine) and consider dosage modification of the CYP450 substrate
There are no human data regarding use in pregnant women to inform a drug-associated risk
Human IgG antibodies are known to cross the placental barrier; therefore, brodalumab may be transmitted from the mother to the developing fetus
- In a combined embryofetal development and prenatal and postnatal development study, no adverse developmental effects were observed in infants born to pregnant monkeys after SC administration during organogenesis through parturition at doses up to 26 times the maximum recommended human dose
Unknown if distributed in human breast milk
Detected in the milk of lactating cynomolgus monkeys
Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the drug, and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition
A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA:Information not available.
Mechanism of Action
Human monoclonal IgG2 antibody that selectively binds to human IL-17RA and inhibits its interactions with cytokines IL-17A, IL-17F, IL-17C, IL-17A/F heterodimer, and IL-25
IL-17RA is a protein expressed on the cell surface and is a required component of receptor complexes used by multiple IL-17 family cytokines
Blocking IL17RA inhibits IL-17 cytokine-induced responses, including the release of proinflammatory cytokines and chemokines
Bioavailability (SC): ~55%
Peak plasma time: ~3 days
Peak plasma concentration: 13.4 mcg/mL
AUC: 111 mcg·day/mL
Vd: 8.9 L
The metabolic pathway has not been characterized
As a human monoclonal IgG2 antibody, brodalumab is expected to be degraded into small peptides and amino acids via catabolic pathways in a manner similar to endogenous IgG
Total clearance: 3 L/day
Allow syringe to reach room temperature (~30 minutes) before injecting
Do not warm in any other way
Do not remove the gray needle cap on the prefilled syringe while allowing it to reach room temperature
Visually inspect for particles and discoloration prior to administration; should appear as a clear to slightly opalescent, colorless to slightly yellow solution; a few translucent to white, amorphous proteinaceous particles may be present
Do not use if solution is cloudy or discolored or if foreign matter is present

Do not inject into areas where the skin is tender, bruised, red, hard, thick, scaly, or affected by psoriasis
Store refrigerated at 2-8°C (36-46°F) in the original carton to protect from light and physical damage during storage
