Insights

Secukinumab-low dose (SEC-L) is the most effective biologic for pediatric psoriasis, achieving high Psoriasis Area and Severity Index (PASI 90) response without increasing adverse events. This finding offers valuable insights for treating young patients with moderate-to-severe psoriasis.

Area of Science:

  • Dermatology
  • Pharmacology
  • Clinical Trials

Background:

  • Pediatric psoriasis affects children with moderate-to-severe skin conditions.
  • Biologic treatments are increasingly used but require efficacy and safety comparisons.
  • Regulatory agencies like the FDA and EMA have approved several biologics.

Purpose of the Study:

  • To compare the efficacy and safety of US Food and Drug Administration (FDA) and European Medicines Agency (EMA) approved biologic treatments for pediatric psoriasis.
  • To identify the most effective biologic treatment for achieving significant Psoriasis Area and Severity Index (PASI) improvement.
  • To assess the risk of discontinuation due to adverse events (DAE) associated with these biologics.

Main Methods:

  • A systematic literature search was conducted on MEDLINE, Embase, and Cochrane Central Register of Controlled Trials until May 7, 2021.
  • Eligible randomized controlled trials (RCTs) were included in a fixed-effect frequentist network meta-analysis (NMA).
  • Primary outcomes were Psoriasis Area and Severity Index 90% improvement (PASI 90) at 12-16 weeks and DAE within the same period. Surface under the cumulative ranking curve (SUCRA) was used for ranking.

Main Results:

  • Five RCTs with 798 pediatric patients were analyzed.
  • All investigated biologic regimens demonstrated significantly higher PASI 90 response compared to placebo.
  • Secukinumab-low dose (SEC-L) ranked highest for PASI 90 response (84.7%), followed by ixekizumab (70.8%), with no significant difference in DAE risk across treatments.

Conclusions:

  • Secukinumab-low dose (SEC-L) emerged as the leading biologic treatment for pediatric psoriasis, offering the best PASI 90 response.
  • SEC-L demonstrated favorable efficacy without an increased risk of adverse events leading to discontinuation.
  • Further long-term studies are recommended to fully understand the sustained effects and safety profile of these biologic treatments.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Inflammatory Bowel Disease IV: Pharmacological Management

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Biopharmaceutics and Pharmacokinetics: Overview

Understanding drugs, drug products, and their performance in pharmaceutical science is pivotal. Drugs, whether simple molecules or complex compounds, are designed to interact with the body's biological systems to diagnose, treat, or prevent diseases. Drug products include various delivery systems such as tablets, capsules, injections, and inhalers. The performance of these drug products is gauged by their ability to deliver the active ingredient to the desired site of action at the...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Model-Independent Approaches for Pharmacokinetic Data: Noncompartmental Analysis

Noncompartmental analyses offer an alternative method for describing drug pharmacokinetics without relying on a specific compartmental model. In this approach, the drug's pharmacokinetics are assumed to be linear, with the terminal phase log-linear. This assumption allows for simplified analysis and interpretation of the drug's behavior in the body.
One important characteristic of noncompartmental analyses is that drug exposure increases proportionally with increasing doses. This...
