Abstract

Insights

Canakinumab offers an effective treatment for Familial Mediterranean Fever (FMF) resistant to colchicine. This interleukin-1 beta (IL-1β) inhibitor shows a favorable safety profile in clinical trials.

Area of Science:

  • Rheumatology
  • Immunology
  • Genetics

Background:

  • Familial Mediterranean Fever (FMF) is the most prevalent hereditary autoinflammatory disease.
  • Colchicine is the standard treatment, but approximately 40-50% of patients exhibit partial or non-response.
  • Understanding pyrin's role in IL-1β regulation has paved the way for anti-IL-1 therapies.

Purpose of the Study:

  • To review the efficacy and safety of anti-interleukin-1 (IL-1) agents, specifically canakinumab, for colchicine-resistant Familial Mediterranean Fever (FMF).

Main Methods:

  • A comprehensive literature search was conducted on PubMed/Medline/Scopus (since 2001) and rheumatologic conference proceedings (since 2011).
  • The search focused on anti-IL-1 treatments for FMF, with a particular emphasis on canakinumab, a humanized IL-1β antibody.
  • Inclusion of unpublished studies from conference proceedings aimed to provide a complete overview.

Main Results:

  • Numerous reports since 2007 demonstrated successful outcomes with anti-IL-1 agents.
  • Canakinumab treatment showed significant success in case reports (2011) and Phase II trials (2014-2015).
  • A Phase III randomized, placebo-controlled trial confirmed significantly superior efficacy of canakinumab over placebo in colchicine-resistant FMF patients.

Conclusions:

  • Canakinumab demonstrated a favorable safety profile comparable to its use in other indications.
  • The drug proved highly effective in achieving primary and secondary outcome measures in a rigorous trial.
  • Canakinumab represents a promising and effective alternative for most patients with colchicine-resistant FMF.

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...

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...

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 Ulcerative Colitis in IBD

Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...
