Definitions

  • This disclosure features methods and compositions for treating diseases of the gastrointestinal tract with a JAK inhibitor.
  • the Janus kinase (JAK) proteins are a family of non-receptor tyrosine kinases that possess a highly conserved kinase domain responsible for its enzymatic activity. Mammals have four members of this family, JAKl, JAK2, JAK3 and Tyrosine kinase 2 (TYK2). These kinases associate with the intracellular portion of cytokine or hormone receptors, and transduce signals through seven members of the STAT transcription factors - STAT1, STAT2, STAT3, STAT4, STAT5A, STAT5B, and STAT6 in various combinations.
  • JAKl promotes signaling of multiple cytokines (e.g., certain type I and type II cytokines), including pro-inflammatory cytokines involved in the pathogenesis of autoimmune diseases.
  • cytokines e.g., certain type I and type II cytokines
  • pro-inflammatory cytokines involved in the pathogenesis of autoimmune diseases Single- nucleotide polymorphisms within the JAK/STAT pathway that confer susceptibility to IBD have been identified (Jostins et al., Host-microbe interactions have shaped the genetic architecture of inflammatory bowel disease, Nature 491 : 119-124, 2012). Both in vivo and in vitro studies have confirmed the role of JAK/STAT signaling in regulating immune responses (O'Shea and Plenge, JAK and STAT signaling molecules in immunoregulation and immune- mediated disease, Immunity 36:542-550, 2012).
  • Tofacitinib selective oral JAK inhibitor (including JAKl and JAK3) has been tested in clinical trials for both ulcerative colitis (Sandborn et al, Tofacitinib, an Oral Janus Kinase Inhibitor, in Active Ulcerative Colitis, New England J.

  • the gastrointestinal (GI) tract generally provides a therapeutic medium for an individual's body.
  • therapeutic drugs may need to be dispensed to specified locations within the small intestine or large intestine, which is more effective than oral administration of the therapeutic drugs to cure some medical conditions.
  • therapeutic drugs applied directly within the small intestine would not be contaminated, digested or otherwise compromised in the stomach, and thus allow a higher dose to be delivered at a specific location within the small intestine.
  • dispensing therapeutic drugs directly within the small intestine inside a human body can be difficult, because a device or mechanism (e.g., special formulation) is needed to carry a therapeutically effective dose of drug to a desired location within the small intestine and then automatically deliver the therapeutic drug at the desired location.
  • a device or mechanism also needs to be operated in a safe manner as the device or mechanism needs to enter the human body.
  • a novel treatment paradigm for inflammatory conditions of the gastrointestinal tract is provided herein in one embodiment.
  • the methods and compositions described herein allow for the regio-specific release of therapeutic drugs at or near the site of disease in the gastrointestinal tract.
  • a therapeutic drug By releasing a therapeutic drug locally instead of systemically, the bioavailability of said drug can be increased at the site of injury and/or relative to a decrease in circulation; thereby, resulting in improved overall safety and/or efficacy and fewer side effects.
  • Advantages may include one or more of increased drug engagement at the target, leading to new and more efficacious treatment regimens; and/or lower systemic drug levels, which means reduced toxicity and reduced immunogenicity in the case of biologies. For patients, clinicians and payors, this means an easier route of administration, fewer co- medicaments (e.g., immunomodulators), fewer side effects, and/or better outcomes.

  • Crohn's disease is the granular, reddish-purple edematous thickening of the bowel wall. With the development of inflammation, these granulomas often lose their circumscribed borders and integrate with the surrounding tissue. Diarrhea and obstruction of the bowel are the predominant clinical features. As with ulcerative colitis, the course of Crohn's disease may be continuous or relapsing, mild or severe, but unlike ulcerative colitis, Crohn's disease is not curable by resection of the involved segment of bowel. Most patients with Crohn's disease require surgery at some point, but subsequent relapse is common and continuous medical treatment is usual. Crohn's disease may involve any part of the alimentary tract from the mouth to the anus, although typically it appears in the ileocolic, small-intestinal or colonic- anorectal regions.
