Ixekizumab (Taltz) for plaque psoriasis: Positive opinion by the European CHMP

Last Updated on

March 04, 2016 –  On February 25, 2016, the Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion, recommending the granting of a marketing authorisation for the medicinal product Ixekizumab (Taltz), intended for the treatment of plaque IL-17A Inhibitorspsoriasis. Ixekizumab (Taltz) will be available as a 80 mg solution for injection. The active substance of Taltz,  Ixekizumab, is an immunosuppressant. Ixekizumab is a monoclonal antibody that binds with high affinity and specificity to both forms of interleukin 17A (IL‑17A and IL‑17A/F). Neutralisation of IL‑17A by Ixekizumab inhibits keratinocyte proliferation and activation which have been implicated in the pathogenesis of psoriasis.

The benefits with Ixekizumab (Taltz) are its statistically significant and clinically relevant effects compared to placebo or etanercept in terms of ‘Psoriasis Area and Severity Index’ (PASI) score 75 and ‘static Physician Global Assessment of 0 or 1 (sPGA (0/1)) at week 12. PASI 90, PASI 100 and sPGA 0 response rates indicating nearly complete/complete clearance were also statistically significantly better with Taltz compared to placebo or Etanercept (Enbrel).

The most frequently reported adverse drug reactions were upper respiratory tract infections. Most of the reactions were mild or moderate in severity.The full indication is: “Taltz is indicated for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy”. It is proposed that Taltz is prescribed by physicians experienced in the treatment and diagnosis of psoriasis.

Detailed recommendations for the use of this product will be described in the summary of product characteristics (SmPC), which will be published in the European public assessment report (EPAR) and made available in all official European Union languages after the marketing authorisation has been granted by the European Commission.

The mode of action of Ixekizumab (Waltz) is very similar if not identical to that of Secukinumab (Cosentyx), which has earlier been approved by both the American Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of plaque psoriasis as well. Both, Ixekizumab and Secukinumab are monoclonal antibodies that bind and inhibit IL 17A.

  • 30-year study identifies need of disease-modifying therapies for maple syrup urine disease January 24, 2020
    A new study analyzes 30 years of patient data and details the clinical course of 184 individuals with genetically diverse forms of Maple Syrup Urine Disease (MSUD), which is among the most volatile and dangerous inherited metabolic disorders. Researchers collected data on survival, hospitalization rates, metabolic crises, liver transplantation, and cognitive outcome. This represents the […]
  • TP53 gene variant in people of African descent linked to iron overload, may improve malaria response January 24, 2020
    In a study by The Wistar Institute and collaborators, a rare, African-specific variant of the TP53 gene called P47S causes iron accumulation in macrophages and other cell types and is associated with poorer response to bacterial infections, along with markers of iron overload in African Americans. Macrophage iron accumulation disrupts their function, resulting in more […]
  • Scientists highlight potential of exposome research January 23, 2020
    Over the last two decades, the health sciences have been transformed by genomics, which has provided insights into genetic risk factors for human disease. While powerful, the genomics revolution has also revealed the limits of genetic determinants, which account for only a fraction of total disease risk. A new article in the journal Science argues […]
  • Researchers uncover mechanism for how common gene therapy vectors enter cells January 23, 2020
    Researchers led by a team at Massachusetts Eye and Ear have identified a novel cellular entry factor for adeno-associated virus vector (AAV) types—the most commonly used viral vectors for in vivo gene therapy. AAVs are vectors—or vehicles—that are created from a virus that is made harmless by molecular engineering, and have shown promise transporting genetic […]
  • Largest-ever study ties over 100 genes to autism January 23, 2020
    More than 100 genes appear to be involved in autism spectrum disorders (ASD), according to the largest genetic study of the condition to date.
  • More than 40% of status epilepticus patients suffer adverse outcomes January 24, 2020
    A new study published in Seizure gives insight into the short-term outcome of patients treated for status epilepticus in Kuopio University Hospital in Finland. The researchers found a 9% risk of death and a 32% risk of functional loss at one month after status epilepticus. The patient's risk of death could be predicted relatively reliably […]
  • A new twist on quantum communication in fiber January 24, 2020
    New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting implications for secure data transfer across optical fiber networks.
  • The regulators active during iron deficiency January 24, 2020
    Iron deficiency is a critical situation for plants, which respond using specific genetic programmes. Biologists from Heinrich Heine University Düsseldorf (HHU) and Michigan State University (MSU) used artificial intelligence methods to examine how to predict regulatory genetic sequences. They have now published the findings from their joint research work in the journal Plant Physiology.
  • Brain-cell helpers powered by norepinephrine during fear-memory formation January 24, 2020
    A sustained state of vigilance will generate a different type of memory than a momentary startle, and these differences are linked to distinct signaling molecules in the brains of mice. Researchers at the RIKEN Center for Brain Science (CBS) have visualized these dynamics in the living mouse brain for the first time, observing two molecular […]
  • What goes up may actually be down January 24, 2020
    A new study in Frontiers in Neuroscience used virtual reality to determine how people plan their movements by 'seeing' gravity using visual cues in the landscape around them, rather than 'feeling it' through changes in weight and balance.
