Definitions

  • the present invention relates to glucagon-like-peptide-2 (GLP-2) analogues and their medical uses for the treatment of short bowel syndrome (SBS), and in particular to the treatments using glepaglutide that result in an early or signficant reduction in the parenteral support (PS) required by patients undergoing GLP-2 therapy, even allowing patients to be weaned off the need for PS.
  • GLP-2 glucagon-like-peptide-2
  • PS parenteral support
  • Human GLP-2 is a 33-amino-acid peptide with the following sequence: Hy-His-Ala-Asp- Gly-Ser-Phe-Ser-Asp-Glu-Met-Asn-Thr-lle-Leu-Asp-Asn-Leu-Ala-Ala-Arg-Asp-Phe-lle- Asn-Trp-Leu-lle-GIn-Thr-Lys-lle-Thr-Asp-OH (SEQ ID NO: 2). It is derived from specific post-translational processing of proglucagon in the enteroendocrine L cells of the intestine and in specific regions of the brainstem. GLP-2 binds to a single G-protein- coupled receptor belonging to the class II glucagon secretin family.
  • GLP-2 has been reported to induce significant growth of the small intestinal mucosal epithelium via the stimulation of stem cell proliferation in the crypts, and by inhibition of apoptosis in the villi (Drucker et al., 1996, Proc. Natl. Acad. Sci. USA 93: 7911-7916). GLP-2 also has growth effects on the colon. Furthermore, GLP-2 inhibits gastric emptying and gastric acid secretion (Wojdemann et al., 1999, J. Clin. Endocrinol. Metab.
  • glucagon-like peptide-2 receptor analogues have therapeutic potential for the treatment of intestinal diseases.
  • the native hGLP- 2 a 33 amino acid gastrointestinal peptide, is not a useful in a clinical setting due to its very short half-life in humans of around 7 minutes for full length GLP-2 [1-33] and 27 minutes for truncated GLP-2 [3-33], In large part, the short half-life is due to degradation by the enzyme dipeptidylpeptidase IV (DPP-IV). Accordingly, there have been attempts in the art to develop GLP-2 receptor agonists with better pharmacokinetic characteristics,
  • GLP-2 analogues with substitutions have been suggested such as e.g., GLP-2 analogues containing Gly substitution at position 2 ([hGly2] GLP-2, teduglutide) which increases the half-life from seven minutes (native GLP-2) to about two hours.
  • Teduglutide is approved for treatment of short bowel syndrome under the names Gattex (in the US) and Revestive (in Europe).
  • WO 2006/117565 (Zealand Pharma A/S) describes GLP-2 analogues which comprise one of more substitutions as compared to [hGly2]GLP-2 and which improved biological activity in vivo and/or improved chemical stability, e.g. as assessed in in vitro stability assays.
  • ZP1848 glepaglutide
  • Dosage regimes for GLP-2 analogues including ZP1848 and its metabolites are described in WO 2018/229252, which also shows that these compounds are effective to increase longitudinal growth of the intestines.
  • Use of GLP-2 analogues, including ZP1848, to treat conditions associated with bile acid synthesis, liver bile acid content, or intestinal bile acid content is described in WO 2020/020904.

  • SBS short bowel syndrome
  • These placebo-controlled studies found that ZP1848 treatment in patients with short bowel syndrome receiving parenteral support (PS), in particular those receiving PS for 3 or more days per week, allowed a subpopulation of patients to be weaned entirely from the parenteral support after only a few weeks of treatment.

  • the individual doses may be for administration via a dosing regime as described elsewhere in this specification.
  • WO 2018/229252 describes that ZP1848 has an unexpectedly long half-life which may enable alternative regimes such as once or twice weekly adminstration, especialy when delivered by subcutaneous injection. Without wishing to be bound by theory, it is believed that the half life of ZP1848 may be due to the combination of the formation of a subcutaneous depot and the formation of metabolites which are slowly released from the subcutaneous depot, and which are also agonistic on the GLP-2 receptor.
  • the subcutaneous depot may be formed on administration through a reaction between the lysine tail of ZP1848 and hyaluronic acid in the subcutaneous compartment.

  • the detemination of the correct amount or volume of PS to provide to patients with SBS who are receiving GLP-2 therapy is a challenge because if PS volume is not adjusted in a timely and appropriate way, patients may experience fluid overload, are at risk of dehydration and may not achieve optimal clinical responses to the therapy. This is further complicated as the PS volume required by a patient will typically vary during the course of GLP-2 therapy depending on their response to the therapy.
  • the assessment of the amount of PS volume required by the patient as GLP-2 therapy progresses is dependent on how long the therapy has continued and the responsiveness of individual patients to it.
  • an initial assessment of PS volume may be carried out within the first few days of GLP-2 therapy and is typically then followed by a weekly assessment during the first month, a monthly assessment over the next 1-3 months, and thereafter an assessment every 3-6 months until the treatment is concluded. This is important as patients may experience a rapid initial response to GLP-2 therapy, improving the function of the small intestine, for example even before any increase in the length of the intestine is observed. This in turn enables the PS volume to be reduced, thereby avoiding the risk of side effects, such as fluid overload.
  • the method or uses may include the step of (a) determining the volume of PS required by the patient at that point in the treatment, (b) comparing it to a baseline PS volume determined at the start of therapy with the GLP- 2 analogue and (c) reducing the frequency or volume of the PS where the patient demonstrates improved function of the intestine, such as the small intestine.
