Ixekizumab, sold under the brand name Taltz, is an injectable medication for the treatment of autoimmune diseases. Chemically, it is a form of a humanized monoclonal antibody. [9] The substance acts by binding interleukin 17A and neutralizing it, reducing inflammation. [10] [11]

Contents

The most common side effects include upper respiratory infections, injection site reactions and fungal (tinea) infections. [12]

The drug was developed by Eli Lilly and Co. and is approved for the treatment of plaque psoriasis in the European Union and the United States as of 2016. [6] [13]

Medical uses

In the United States, ixekizumab is indicated for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy, active psoriatic arthritis, active ankylosing spondylitis, and active non-radiographic axial spondyloarthritis with objective signs of inflammation. [14] In the European Union it is indicated for the treatment of moderate-to-severe plaque psoriasis [6] and as a second-line therapy for active psoriatic arthritis. [6] [10]

In studies, the drug reduced the Psoriasis Area and Severity Index by at least 75% (PASI75) in 82–89% of patients during the first three months of treatment (depending on the dosing scheme), and 40% of patients experienced a complete absence of psoriasis symptoms (PASI100). In the placebo group, PASI75 was reached in 4% of patients, and PASI100 in none; in the group of patients receiving etanercept, an older anti-psoriasis drug, PASI75 was reached in 48%. Until the 60th study week, 11–44% of ixekizumab treated patients relapsed (again, depending on the dosing scheme), as compared to 84% under placebo. [10] [15]

Contraindications

The medication is contraindicated for patients with certain infections such as active tuberculosis. [10] [ contradictory ]

Adverse effects

In studies, ixekizumab increased the rate of infections (27% of ixekizumab treated patients, compared to 23% under placebo), including severe ones (0.6% versus 0.4% under placebo). Other common side effects included injection site reactions such as redness and pain (13–17% versus 3%), [16] oropharyngeal pain (1%) and nausea (1–2%). [10] Other common adverse effects (≥5.0%) include nasopharyngitis, upper respiratory tract infection, arthralgia, headache, back pain, hypertension, bronchitis, diarrhea, sinusitis, and urinary tract infection. [17]

In a review of 18,025 patient years (n=6892 patients), no anaphylaxis was reported, no reactivation of tuberculosis, and low incidence rate of candida infection and serious infections was found. Incidence rates decreased or remained constant over time. [17]

Ixekizumab does not have an increased risk of adverse effects in the elderly. [18]

Overdose

Up to fourfold doses have been given in studies without causing serious side effects. [10]

Interactions

No interaction studies have been done. Ixekizumab and interleukin 17 are not known to interact with cytochrome P450 (CYP) liver enzymes. Since inflammation suppresses CYP activity, it is theorized that ixekizumab could neutralize this effect and lower blood plasma concentrations of drugs that are metabolized by CYP enzymes, such as warfarin. [10]

Pharmacology

Mechanism of action

Ixekizumab binds to interleukin 17 (IL-17A), a pro-inflammatory cytokine, and blocks its action. Among other things, IL-17A stimulates proliferation and activation of keratinocytes in the skin. [10] This mechanism is similar to that of another anti-psoriasis antibody, brodalumab, which binds to the interleukin-17 receptor. [19]

The antibody has affinity to the homodimer IL-17A and the heterodimer IL-17A/F, but not to other members of the interleukin 17 family. [10]

Pharmacokinetics

After subcutaneous injection, ixekizumab has a bioavailability of 60–81%; [7] bioavailability is higher in the thigh than the abdomen or arm. [7] Highest blood plasma concentrations are reached after four to seven days after a single dose. [8] With the usual dosing scheme (loading plus a dose every two weeks), steady state concentrations are reached in the eighth week on average. [10]

Like other antibodies, ixekizumab is probably degraded by proteolysis. Its elimination half-life is 14–18 days. [10] [20] The volume of distribution is 7.11 L. [8] Mean clearance is 0.39 L/day. [8] There is no difference in rate of clearance between elderly and younger patients. [18] Increased body weight increases the volume of distribution and clearance rate. [8] Ixekizumab displays linear pharmacokinetics across doses. [20]

Pharmacokinetic data is similar for autoinjector pens and prefilled syringes. [7]

Chemistry

Ixekizumab is a complete monoclonal antibody of the subclass IgG4, consisting of two light chains and two heavy chains linked by disulfide bridges. Both heavy chains are glycosylated at the asparagine in position 296. In the hinge region, a serine is replaced by a proline to reduce formation of half-antibodies and heterodimers in the manufacturing process. The terminal lysine found in wild-type IgG4 is removed. The antibody is produced in Chinese hamster ovary cells. [9] [21]

History

Clinical trials included a Phase II trial of patients with moderate to severe psoriasis, [19] and a Phase III open-label trial. [22] [ full citation needed ]

Ixekizumab was approved by the US Food and Drug Administration (FDA) in March 2016, for the treatment of adults with moderate-to-severe plaque psoriasis [12] and by the European Medicines Agency (EMA) in April 2016. [6] The safety and efficacy of ixekizumab were established in three randomized, placebo-controlled clinical trials with a total of 3,866 participants with plaque psoriasis who were candidates for systemic or phototherapy therapy. [12] The FDA approved ixekizumab based on the evidence from three clinical trials of 1958 participants with moderate to severe psoriasis. [23] The trials were conducted in the US, Canada, Europe, Russia, Mexico, Chile, Argentina, Japan and Australia. [23]

In December 2017, the FDA approved it for active psoriatic arthritis. [24]

Psoriasis is a long-lasting, noncontagious autoimmune disease characterized by patches of abnormal skin. These areas are red, pink, or purple, dry, itchy, and scaly. Psoriasis varies in severity from small localized patches to complete body coverage. Injury to the skin can trigger psoriatic skin changes at that spot, which is known as the Koebner phenomenon.

Infliximab, a chimeric monoclonal antibody, sold under the brand name Remicade among others, is a medication used to treat a number of autoimmune diseases.

It is given by slow injection into a vein, typically at six- to eight-week intervals.

<span class="mw-page-title-main">Psoriatic arthritis</span> Long-term inflammatory arthritis

Psoriatic arthritis (PsA) is a long-term inflammatory arthritis that occurs in people affected by the autoimmune disease psoriasis. The classic feature of psoriatic arthritis is swelling of entire fingers and toes with a sausage-like appearance. This often happens in association with changes to the nails such as small depressions in the nail (pitting), thickening of the nails, and detachment of the nail from the nailbed. Skin changes consistent with psoriasis frequently occur before the onset of psoriatic arthritis but psoriatic arthritis can precede the rash in 15% of affected individuals. It is classified as a type of seronegative spondyloarthropathy.

Adalimumab, sold under the brand name Humira and others, is a disease-modifying antirheumatic drug and monoclonal antibody used to treat rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, plaque psoriasis, hidradenitis suppurativa, and uveitis. It is administered by subcutaneous injection. It works by inactivating tumor necrosis factor-alpha (TNFα).

Biological response modifiers (BRMs) are substances that modify immune responses. They can be endogenous or exogenous, and they can either enhance an immune response or suppress it. Some of these substances arouse the body's response to an infection, and others can keep the response from becoming excessive. Thus they serve as immunomodulators in immunotherapy, which can be helpful in treating cancer and in treating autoimmune diseases, such as some kinds of arthritis and dermatitis. Most BRMs are biopharmaceuticals (biologics), including monoclonal antibodies, interleukin 2, interferons, and various types of colony-stimulating factors. "Immunotherapy makes use of BRMs to enhance the activity of the immune system to increase the body's natural defense mechanisms against cancer", whereas BRMs for rheumatoid arthritis aim to reduce inflammation.
