<\/span><\/h2>\nIxekizumab (Taltz\u00ae<\/sup>) is a humanized monoclonal<\/span> immunoglobulin<\/span> Sun antibody<\/span> Developed by Eli Lilly and Company which has been approved in the USA. USA (March 2016) and Europe (April 2016) as treatment for license plate<\/span> psoriasis.<\/p>\nIxekizumab is a specific inhibitor of interleukin<\/span>-17A (IL-17A), a pro-inflammatory<\/span> cytokine<\/span> That has a role in the development of various inflammatory conditions, including psoriasis.<\/p>\nthe effectiveness<\/span> of ixekizumab as treatment for moderate to severe plaque psoriasis has been evaluated in three randomized placebo<\/span>controlled trials, UNCOVER-1, UNCOVER-2 and UNCOVER-3. UNCOVER-2 and UNCOVER-3 also compared ixekizumab with etanercept.<\/p>\n<\/span>Experience in clinical trials.<\/span><\/h2>\n<\/span>UNCOVER-1: efficacy and Adverse reactions<\/span>
\n<\/span><\/h3>\nUncover-1 was a prospect, double-blind<\/span>, a multicenter trial that consisted of 1296 patients randomized 1: 1: 1 to receive ixekizumab 80 mg every two weeks (Q2W), ixekizumab 80 mg every four weeks (Q4W) or placebo, respectively.<\/p>\n\n- Patients in the ixekizumab groups received a single initial dose of 160 mg at week 0 followed by 80 mg Q2W or Q4W.<\/li>\n
- All patients received two subcutaneous<\/span> injections (ixekizumab or placebo) at week 0 and a subcutaneous injection (ixekizumab or placebo) at week 2, 4, 6, 8, and 10.<\/li>\n
- In this study, theprimary<\/span> The efficacy end point at 12 weeks was an improvement of 75% in the composite severity index of the psoriasis area (PASI<\/span>) score and at least a 2 point increase base<\/span> in the Static Physician Global Assessment (sPGA) 0 or 1.<\/li>\n
- PASI measures the extent and severity of psoriasis by evaluating the redness, thickness, and average desquamation of skin lesions (each rated zero to four. scale<\/span>), weighted by the body surface area of the affected skin.<\/li>\n
- The sPGA is the physician's assessment of the severity of a patient's psoriasis lesions in general at a specific time and is a necessary measure that the FDA uses to assess effectiveness.<\/li>\n
- The 89.1% and 82.6% of the patients treated with ixekizumab once every 2 (n = 433) or 4 (n = 432) weeks, respectively for 12 weeks, achieved an improvement in the PASI of \u226575% (PASI 75) in Comparison with 3.5% for placebo recipients (n = 431; p <0.001 for both ixekizumab regimens versus placebo).<\/li>\n
- The percentage of achievement of sPGA 0 or 1 was 81.8% and 76.4% for ixekizumab Q2W and Q4W, respectively, compared to 3.2% in those taking a placebo (P<\/em> <0.001 vs placebo).<\/li>\n
- After 12 weeks, patients who responded to ixekizumab were randomized to 48 weeks of treatment with ixekizumab 80 mg every 4 (n = 229) or 12 (n = 227) weeks or placebo (n = 226).<\/li>\n
- At week 60, the sPGA of 0 or 1, PASI 75, and PASI 100 were maintained at 72.9, 77.7, and 52% for ixekizumab receptors, respectively.<\/li>\n
- The most common (> 1%) adverse events<\/span> were nasopharyngitis<\/span>, erythema<\/span> and pain at the injection site.<\/li>\n
- The proportions of patients with candida infection<\/span> at 12 weeks they were 0.9% and 0.6% for ixekizumab Q2W and ixekizumab Q4W, respectively, compared to 0.5% for placebo.<\/li>\n
- \nAdverse event<\/span> Comparisons are not statistically significant, as the study was designed to detect differences in efficacy rather than rates of adverse events.<\/li>\n<\/ul>\n
<\/span>UNCOVER-2: efficacy and adverse events<\/span><\/h3>\nIn UNCOVER-2, 1,224 patients were randomly assigned to receive subcutaneous placebo (n = 168), etanercept (n = 358), or ixekizumab every 2 weeks (Q2W; n = 351) or every 4 weeks (Q4W; n = 347).<\/p>\n
\n- Participants received subcutaneous placebo, etanercept (50 mg twice weekly), or an 80 mg injection of ixekizumab every other week, or every four weeks after a starting dose of 160 mg.<\/li>\n
- Blinding was maintained with a double simulation design.<\/li>\n
- The co-primary efficacy end points were proportions of patients achieving a sPGA score of 0 or 1 and an improvement of 75% or more in PASI at week 12. Analysis was by intention to treat.<\/li>\n
- PASI 90, PASI 100, numerical rating scale for itching and Dermatology<\/span> Quality of life index (DLQI<\/span>) were included as secondary endpoints in the study.<\/li>\n

- The proportion of patients achieving PASI 75 was 89.7% and 77.5% for ixekizumab Q2W and Q4W, respectively, compared to 2.4% in placebo (P<\/em> <0.0001 vs. placebo).<\/li>\n
- The percentage of achievement of sPGA 0 or 1 was 83.2% and 72.9% for ixekizumab Q2W and Q4W, respectively, compared to 2.4% in placebo (P<\/em> <0.0001 vs. placebo).<\/li>\n
- Both ixekizumab dosing regimens were statistically higher<\/span> to placebo in terms of PASI 90, PASI 100 and DLQI (P<\/em> <0.0001 vs. placebo).<\/li>\n
- Compared to etanercept 50 mg twice weekly, ixekizumab 80 mg Q2W and Q4W were shown to be statistically superior in terms of the proportion of patients achieving PASI 75 and sPGA 0 or 1 at week 12 (P<\/em> <0.0001 vs etanercept).<\/li>\n

- All Candida<\/em> Infections were mild to moderate in intensity and resolved without interruption of treatment.<\/li>\n
- The 12-week serious adverse event rates were 1.4%, 2.3%, and 1.2% for patients receiving ixekizumab Q2W, ixekizumab Q4W, or placebo, respectively.<\/li>\n
- At 12 weeks, neutropenia<\/span> it was reported in 8.6% of patients taking ixekizumab Q2W and 7.6% of patients taking ixekizumab Q4W, compared to 4.8% of patients taking placebo.<\/li>\n
- Neutropenia cases were mild and transitory, without associated infections.<\/li>\n
- It is important to note that comparisons of adverse events were not statistically significant as the studies had the power to detect differences in efficacy rather than rates of adverse events.<\/li>\n<\/ul>\n
<\/span>UNCOVER-3: efficacy and adverse events<\/span><\/h3>\nUNCOVER-3 patients were randomized to receive placebo (n = 193), etanercept (n = 382), ixekizumab every 2 weeks (Q2W; n = 385), or ixekizumab every 4 weeks (Q2W; n = 386).<\/p>\n
