Siliq

BRODALUMAB

Standard Dose

2 DOSAGE AND ADMINISTRATION Administer 210 mg of SILIQ by subcutaneous injection at Weeks 0, 1, and 2 followed by 210 mg every 2 weeks. ( 2.2 ) 2.1 Tuberculosis Assessment Prior to Initiation of SILIQ Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with SILIQ [see Warnings and Precautions ( 5.4 )]. 2.2 Dosage The recommended SILIQ dose is 210 mg administered by subcutaneous injection at Weeks 0, 1, and 2 followed by 210 mg every 2 weeks. If an adequate response has not been achieved after 12 to 16 weeks of treatment with SILIQ, 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. 2.3 Important Administration Instructions Administer SILIQ subcutaneously. Each prefilled syringe is for single dose only. Instruct patients to review the Medication Guide before use [see Medication Guide] . SILIQ is intended for use under the guidance and supervision of a healthcare professional. Patients may self-inject SILIQ when deemed appropriate by a healthcare professional and after proper training in subcutaneous injection technique using the prefilled syringe. Advise patients who are self-administering to inject the full dose and to read the Instructions for Use before administration [ see Instructions for Use] . Do not inject SILIQ into areas where the skin is tender, bruised, red, hard, thick, scaly, or affected by psoriasis. 2.4 Preparation of SILIQ Prefilled Syringe • Allow SILIQ prefilled syringe to reach room temperature (approximately 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 SILIQ for particles and discoloration prior to administration. SILIQ is a clear to slightly opalescent, colorless to slightly yellow solution. Do not use SILIQ if it is cloudy or discolored or if foreign matter is present. • Instruct patients to use the prefilled syringe and to inject the full amount (1.5 mL), which provides 210 mg of SILIQ, according to the directions provided in the Instructions for Use [see Instructions for Use].

Warnings and cautions 5 WARNINGS AND PRECAUTIONS • Hypersensitivity Reactions: Serious hypersensitivity reactions, including anaphylaxis, may occur. If a serious hypersensitivity reaction occurs, immediately discontinue SILIQ and initiate appropriate therapy. ( 5.3 ) • Infections: Serious infections have occurred. Consider the risks and benefits prior to initiating SILIQ in patients with a chronic infection or a history of recurrent infection. Instruct patients to seek medical advice if signs or symptoms of clinically important chronic or acute infection occur. If a serious infection develops, discontinue SILIQ until the infection resolves. ( 5.4 ) • Tuberculosis (TB): Evaluate patients for TB infection prior to initiating treatment with SILIQ. ( 5.5 ) • Eczematous Eruptions: The onset of eczematous eruptions was variable, ranging from days to months after the first dose of SILIQ. Some cases of severe eczematous eruptions resulted in hospitalization. Treatment may need to be discontinued to resolve the eczematous eruption. Some patients with limited psoriasis treatment options were successfully treated for eczema while continuing SILIQ. ( 5.6 ) • Crohn’s Disease: Crohn’s disease occurred during clinical trials. Discontinue SILIQ if patient develops Crohn’s disease while taking SILIQ. ( 5.7 ) • Immunizations: Avoid using live vaccines concurrently with SILIQ. ( 5.8 ) 5.1 Suicidal Ideation and Behavior Suicidal ideation and behavior, including four completed suicides, occurred in subjects treated with SILIQ in the psoriasis clinical trials. There were no completed suicides in the 12-week placebo-controlled portion of the trials. SILIQ users with a history of suicidality or depression had an increased incidence of suicidal ideation and behavior as compared to users without such a history [see Adverse Reactions ( 6.1 )]. A causal association between treatment with SILIQ and increased risk of suicidal ideation and behavior has not been established. Prescribers should weigh the potential risks and benefits before using SILIQ in patients with a history of depression or suicidality. Patients with new or worsening symptoms of depression or suicidali

Boxed Warning

WARNING: SUICIDAL IDEATION AND BEHAVIOR Suicidal ideation and behavior, including completed suicides, have occurred in patients treated with SILIQ. Prior to prescribing SILIQ, 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 [ see Warnings and Precautions ( 5.1 )]. Because of the observed suicidal behavior in subjects treated with SILIQ, SILIQ is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the SILIQ REMS Program [see Warnings and Precautions ( 5.2 )]. WARNING: SUICIDAL IDEATION AND BEHAVIOR See full prescribing information for complete boxed warning. • Suicidal ideation and behavior, including completed suicides, have occurred in patients treated with SILIQ. ( 5.1 , 6.1 ) • Prior to prescribing, weigh potential risks and benefits in patients with a history of depression and/or suicidal ideation or behavior. ( 5.1 ) • Patients with new or worsening suicidal thoughts and behavior should be referred to a mental health professional, as appropriate.

Monitoring

• 5 WARNINGS AND PRECAUTIONS • Hypersensitivity Reactions: Serious hypersensitivity reactions, including anaphylaxis, may occur.
• If a serious hypersensitivity reaction occurs, immediately discontinue SILIQ and initiate appropriate therapy.
• ( 5.3 ) • Infections: Serious infections have occurred.
• Consider the risks and benefits prior to initiating SILIQ in patients with a chronic infection or a history of recurrent infection.

Interaction Notes

• 7 DRUG INTERACTIONS CYP450 Substrates The formation of CYP450 enzymes can be altered by increased levels of certain cytokines (e.g., IL-1, IL-6, IL-10, TNFα, IFN) during chronic inflammation.
• Treatment with SILIQ may modulate serum levels of some cytokines.
• Therefore, upon initiation or discontinuation of SILIQ in patients who are receiving concomitant drugs which are CYP450 substrates, particularly those with a narrow therapeutic index, consider monitoring for effect (e.g., for warfarin) or drug concentration (e.g., for cyclosporine) and consider dosage modification of the CYP450 substrate [see Clinical Pharmacology ( 12.3 )].
