Cosentyx (secukinumab) - 4 indications

Scroll down for information on each indication:

• for the treatment of plaque psoriasis in patients six years of age and older; approved January 2015; June 2021
• for the treatment of ankylosing spondylitis; approved January 2016
• for the treatment of psoriatic arthritis; approved January 2016
• for the treatment of active non-radiographic axial spondyloarthritis; approved June 2020

General Information

Cosentyx (secukinumab) is a human IgG1 monoclonal antibody that selectively binds to the interleukin-17A (IL-17A) cytokine and inhibits its interaction with the IL-17 receptor. IL-17A is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Secukinumab inhibits the release of proinflammatory cytokines and chemokines. 

Cosentyx is specifically indicated for the following indications:

• moderate to severe plaque psoriasis in patients 6 years and older who are candidates for systemic therapy or phototherapy
• adult patients with active psoriatic arthritis
• adult patients with active ankylosing spondylitis
• adult patients with active non-radiographic axial spondyloarthritis (nraxSpA) with objective signs of inflammation

Cosentyx is supplied as a solution for subcutaneous injection. Perform the following evaluations prior to Cosentxy initiation:

• Evaluate patients for tuberculosis (TB) infection. Cosentyx initiation is not recommended in patients with active TB infection. Initiate treatment of latent TB prior to initiation of Cosentyx
• Complete all age-appropriate vaccinations as recommended by current immunization guidelines prior to initiating treatment with Cosentyx

Mechanism of Action

Cosentyx (secukinumab) is a human IgG1 monoclonal antibody that selectively binds to the interleukin-17A (IL-17A) cytokine and inhibits its interaction with the IL-17 receptor. IL-17A is a naturally occurring cytokine that is involved in normal inflammatory and immune responses. Secukinumab inhibits the release of proinflammatory cytokines and chemokines.  

Side Effects

Adverse effects associated with the use of Cosentyx may include, but are not limited to, the following:

• nasopharyngitis
• diarrhea
• upper respiratory tract infection

Indication 1 - the treatment of plaque psoriasis in patients six years of age and older

approved January 2015 (adults); June 2021 (pediatrics)

Dosing/Administration

Adults

• The recommended dosage is 300 mg by subcutaneous injection at Weeks 0, 1, 2, 3, and 4 followed by 300 mg every 4 weeks. Each 300 mg dosage is given as 2 subcutaneous injections of 150 mg. For some patients, a dose of 150 mg may be acceptable.

Pediatric Patients

• The recommended dosage for pediatric patients 6 years of age and older is based on body weight (see table below) and administered by subcutaneous injection at Weeks 0, 1, 2, 3, and 4 followed by dosing every 4 weeks.

Body Weight at Time of Dosing	Recommended Dose
Less than 50 kg	75 mg
Greater than or equal to 50 kg	150 mg

Clinical Trial Results

The FDA approval of Cosentyx for plaque psoriasis was based on four multicenter, randomized, double-blind, placebo-controlled trials in 2,403 subjects (691 randomized to Cosentyx 300 mg, 692 to Cosentyx 150 mg, 694 to placebo, and 323 to a biologic active control) 18 years of age and older with plaque psoriasis who had a minimum body surface area involvement of 10%, and Psoriasis Area and Severity Index (PASI) score greater than or equal to 12, and who were candidates for phototherapy or systemic therapy. In all trials, the endpoints were the proportion of subjects who achieved a reduction in PASI score of at least 75% (PASI 75) from baseline to Week 12 and treatment success (clear or almost clear) on the Investigator’s Global Assessment modified 2011 (IGA). In these studies, Cosentyx met all primary and key secondary endpoints, including Psoriasis Area and Severity Index (PASI) 75 and 90 and Investigator's Global Assessment modified 2011 (IGA) 0/1 responses, showing significant skin clearance at Week 12.

Indication 2 - the treatment of ankylosing spondylitis

approved January 2016

Dosing/Administration

Administer Cosentyx with or without a loading dosage by subcutaneous injection. The recommended dosage:

• With a loading dosage is 150 mg at Weeks 0, 1, 2, 3, and 4 and every 4 weeks thereafter
• Without a loading dosage is 150 mg every 4 weeks

If a patient continues to have active ankylosing spondylitis, consider a dosage of 300 mg every 4 weeks.

Clinical Trial Results

The FDA approval of Cosentyx for active ankylosing spondylitis (AS) was based on the efficacy and safety outcomes from two AS and two PsA placebo-controlled Phase III studies which included more than 1,500 adult patients with either AS or PsA. In the studies, Cosentyx met the primary endpoints achieving statistically significant improvements versus placebo in the signs and symptoms of AS and PsA, as measured by at least a 20% improvement in the Assessment of Spondyloarthritis International Society criteria (ASAS20) at Week 16 and a 20% reduction in the American College of Rheumatology (ACR20) response criteria at Week 24, respectively.

Indication 3 - the treatment of psoriatic arthritis

approved January 2016

Dosing/Administration

For psoriatic arthritis patients with coexistent moderate to severe plaque psoriasis, use the dosing and administration recommendations for plaque psoriasis.

For other psoriatic arthritis patients, administer Cosentyx with or without a loading dosage by subcutaneous injection. The recommended dosage:

• With a loading dosage is 150 mg at Weeks 0, 1, 2, 3, and 4 and every 4 weeks thereafter
• Without a loading dosage is 150 mg every 4 weeks

If a patient continues to have active psoriatic arthritis, consider a dosage of 300 mg every 4 weeks.

Cosentyx may be administered with or without methotrexate.

Clinical Trial Results

The FDA approval of Cosentyx for active psoriatic arthritis (PsA) was based on the efficacy and safety outcomes from two AS and two PsA placebo-controlled Phase III studies which included more than 1,500 adult patients with either AS or PsA. In the studies, Cosentyx met the primary endpoints achieving statistically significant improvements versus placebo in the signs and symptoms of AS and PsA, as measured by at least a 20% improvement in the Assessment of Spondyloarthritis International Society criteria (ASAS20) at Week 16 and a 20% reduction in the American College of Rheumatology (ACR20) response criteria at Week 24, respectively.

Indication 4 -  the treatment of active non-radiographic axial spondyloarthritis

approved June 2020

Dosing/Administration

Administer Cosentyx with or without a loading dosage by subcutaneous injection. The recommended dosage:

• With a loading dosage is 150 mg at Weeks 0, 1, 2, 3, and 4 and every 4 weeks thereafter
• Without a loading dosage is 150 mg every 4 weeks

Clinical Trial Results

The FDA approval of Cosentyx for active non-radiographic axial spondyloarthritis was based on the Phase 3 PREVENT trial, which demonstrated the efficacy of Cosentyx in active non-radiographic axial spondyloarthritis (nr-axSpA), which is part of the axial spondyloarthritis (axSpA) disease spectrum. In that study, Cosentyx met the primary endpoint achieving statistically significant improvements in the signs and symptoms of nr-axSpA.
