Definitions
- the present invention relates to a growth hormone receptor antagonist comprising a growth hormone variant in which at least one amino acid in the amino acid sequence of a growth hormone is replaced by another amino acid.
- Growth hormone is an endocrine hormone that promotes growth.
- Human growth hormone (hGH) is secreted from the pituitary gland and acts on various tissues including the liver. It binds with the extracellular domain of the human growth hormone receptor (hGHR) belonging to the class I cytokine receptor superfamily that forms dimers in complex with hGH (JF Bazan, Haemopoietic receptors and helical cytokines, Immunol. ) 350-354.), Subsequent signal transduction increases the expression of insulin-like growth factor I (IGF-1) (FF Casanueva, Physiology of growth hormone secretion and action, Endocrinol. Metab. ) 483-517 .; H.
- IGF-1 insulin-like growth factor I
- hGHRA hGH receptor antagonist
- HGHRA which can last a long time in the human body, can improve the quality of life of patients by reducing the number of doses.
- Pegvisomant is commercially available and commercially available as a pegylated version of hGH antagonist (MO Thorner, CJ Strasburger, Z. Wu, M. Straume, M. Bidlingmaier, SS Pezzoli, K. Zib, JC Scarlett, WF Bennett, Growth hormone GH) receptor blockade with a PEG-modified GH (B2036-PEG) lowers serum insulin-like growth factor-I but does not acutely stimulate serum GH, J. Clin. Endocrinol Metab 84 (1999) 2098-2103.
- Pegvisomant is to increase the molecular size by attaching polyethylene glycol polymer to the therapeutic protein so that it remains in the bloodstream without being filtered in the kidney (RJ Ross, KC Leung, M. Maamra, W.
- pegvisomant Another aspect of pegylation is to protect the protein from proteolytic enzymes (S. Jevsevar, M. Kunststoffelj, VG Porekar, PEGylation of therapeutic proteins, Biotechnol. J. 5 (2010) 113-128. Doi: 10.1002 / biot .200900218.).
- pegylation of therapeutic proteins may be limited in its usefulness.
- the pegylation process requires a series of chemical reactions, which are not cost effective and the reaction products are generally not homogeneous. As a result, additional purification steps, which are generally difficult to achieve, are required.
- Pegylated proteins also appear to be safe when using small size polyethylene glycols (eg, 5 kDa), but animal studies have shown that renal vacuolation as well as the appearance of antibodies to pegylation As you can see there is still a safety issue.
- the pegylated protein tends to have a lower binding capacity to protein receptors than the original protein (RP Garay, R. El-Gewely, JK Armstrong, G. Garratty, P.
