Definitions

  • the invention provides stable pharmaceutical compositions comprising tumor necrosis factor receptor Fc fusion protein (TNFR:Fc).
  • TNFR:Fc tumor necrosis factor receptor Fc fusion protein
  • the invention also provides methods of manufacturing the composition, method of administration and kits containing the same.
  • Tumor necrosis factor (TNF) alpha is a cytokine that promotes the inflammation and its associated signs by binding to its receptor. It is produced by macrophages and many other immune cells. It is involved in pathogenesis of many inflammatory disorders like rheumatoid arthritis, psoritic arthritis, SLE, Crohn's disease etc.
  • Hohmann et al Hohmann et al (Hohmann et al. 1989 J Biol Chem. 25, 14927-34) identified 2 distinct receptors of TNF-alpha which are present on different cell types viz. myeloid cells and epithelial cells. Using monoclonal antibodies, Brockhaus et al (Brockhaus et al. 1990 ProcNatlAcadSci USA., 87(8), 3127-31) demonstrated that both TNF-alpha and beta bind to both the receptors with high affinity.
  • Tumor necrosis factor-alpha is a central regulator of inflammation, and TNF-alpha antagonists may be effective in treating inflammatory disorders in which TNF-alpha plays an important pathogenetic role. Inhibition of TNF has proven to be an effective therapy for patients with rheumatoid arthritis and other forms of inflammatory disease including psoriasis, psoriatic arthritis, and ankylosing spondylitis, inflammatory bowel disease.
  • TNF-alpha antagonist is Etanercept.
  • Etanercept is a dimeric fusion protein produced by recombinant DNA technology where gene of soluble, ligand binding portion of TNF receptor 2 is fused with gene of Fc component of human IgG1 to give the desired fusion protein (U.S. Pat. No. 7,648,702).
  • Etanercept is expressed in CHO cells.
  • the Fc component of Etanercept lacks CH1 domain but has CH2, CH3 domains and hinge region.
  • the fusion protein has approximate molecular weight of 150 kD and consists of 934 amino acids.
  • Etanercept interferes with TNF and acts as a TNF inhibitor due to which it can be used as a biopharmaceutical to treat autoimmune diseases. It prevents progressive destruction of joints in patients with rheumatoid arthritis and the arthritis of psoriasis.
  • Etanercept Due to its unique structure, Etanercept binds 50-100 folds more efficiently to TNF alpha than its endogenous receptor (Gofee et. al. 2003 J Am AcadDermatol. 49, S105-111, Strober 2005 SeminCutan Med Surg. 24; 28-36). Additionally, due to its dimeric nature it can bind to 2 TNF alpha molecules as compared to one bound by endogenous receptor. Conjugation of this molecule to Fc region of IgG increases the half life as compared to endogenous soluble form. Commercially, Etanercept is available in both Lyophilized and liquid forms.
  • compositions The most important feature of a composition is to help the protein to retain its structural conformation or its activity.
  • stability of protein in a composition can be related with long-term storage. It is understood to mean that the active polypeptide of the pharmaceutical composition does not substantially lose its activity as compared to the composition at the beginning of storage.
  • Isoelectric Point which is generally defined as the pH at which a polypeptide carries no net charge. It is known in the art that protein solubility is typically lowest when the pH of the solution is equal to the isoelectric point (pI) of the protein.
  • the Tm of the Fab domain of a protein is a good indicator of the thermal stability of a protein and may further provide an indication of the shelf-life.
  • Tm values of proteins determined by differential scanning calorimetry give insight into heat-induced changes in protein conformation, mechanisms of protein unfolding and stabilization in solution. A lower Tm indicates less stability of a protein in given solution, whereas a higher Tm indicates a better stability of the protein.
  • the Tm of the protein will vary based on the formulation composition which in turn reflects its stability in respective formulation.
  • both aqueous and lyophilized compositions of proteins can lose active protein due to aggregation or degradation. Aggregation of the protein can lead to immunogenicity and is undesirable. Since the concentration of Etanercept used in the composition is high, there is a likely possibility of protein aggregation during long term storage. To improve the stability of the protein either the concentration of the existing excipients can be varied or new excipients can be added to modify the composition.

    • FIELD OF INVENTION
  • The invention provides stable pharmaceutical compositions comprising tumor necrosis factor receptor Fc fusion protein (TNFR:Fc). The invention also provides methods of manufacturing the composition, method of administration and kits containing the same.
    • BACKGROUND OF INVENTION
  • Tumor necrosis factor (TNF) alpha is a cytokine that promotes the inflammation and its associated signs by binding to its receptor. It is produced by macrophages and many other immune cells. It is involved in pathogenesis of many inflammatory disorders like rheumatoid arthritis, psoritic arthritis, SLE, Crohn's disease etc. Hohmann et al (Hohmann et al. 1989 J Biol Chem. 25, 14927-34) identified 2 distinct receptors of TNF-alpha which are present on different cell types viz. myeloid cells and epithelial cells. Using monoclonal antibodies, Brockhaus et al (Brockhaus et al. 1990 ProcNatlAcadSci USA., 87(8), 3127-31) demonstrated that both TNF-alpha and beta bind to both the receptors with high affinity.
  • Tumor necrosis factor-alpha (TNF-alpha) is a central regulator of inflammation, and TNF-alpha antagonists may be effective in treating inflammatory disorders in which TNF-alpha plays an important pathogenetic role. Inhibition of TNF has proven to be an effective therapy for patients with rheumatoid arthritis and other forms of inflammatory disease including psoriasis, psoriatic arthritis, and ankylosing spondylitis, inflammatory bowel disease. One such TNF-alpha antagonist is Etanercept.
  • Etanercept is a dimeric fusion protein produced by recombinant DNA technology where gene of soluble, ligand binding portion of TNF receptor 2 is fused with gene of Fc component of human IgG1 to give the desired fusion protein (U.S. Pat. No. 7,648,702). Etanercept is expressed in CHO cells. The Fc component of Etanercept lacks CH1 domain but has CH2, CH3 domains and hinge region. The fusion protein has approximate molecular weight of 150 kD and consists of 934 amino acids. Etanercept interferes with TNF and acts as a TNF inhibitor due to which it can be used as a biopharmaceutical to treat autoimmune diseases. It prevents progressive destruction of joints in patients with rheumatoid arthritis and the arthritis of psoriasis.
  • Due to its unique structure, Etanercept binds 50-100 folds more efficiently to TNF alpha than its endogenous receptor (Gofee et. al. 2003 J Am AcadDermatol. 49, S105-111, Strober 2005 SeminCutan Med Surg. 24; 28-36). Additionally, due to its dimeric nature it can bind to 2 TNF alpha molecules as compared to one bound by endogenous receptor. Conjugation of this molecule to Fc region of IgG increases the half life as compared to endogenous soluble form. Commercially, Etanercept is available in both Lyophilized and liquid forms.
  • The most important feature of a composition is to help the protein to retain its structural conformation or its activity. The stability of protein in a composition can be related with long-term storage. It is understood to mean that the active polypeptide of the pharmaceutical composition does not substantially lose its activity as compared to the composition at the beginning of storage.
  • All polypeptides have an Isoelectric Point (pI), which is generally defined as the pH at which a polypeptide carries no net charge. It is known in the art that protein solubility is typically lowest when the pH of the solution is equal to the isoelectric point (pI) of the protein.
  • The Tm of the Fab domain of a protein is a good indicator of the thermal stability of a protein and may further provide an indication of the shelf-life. Tm values of proteins determined by differential scanning calorimetry, give insight into heat-induced changes in protein conformation, mechanisms of protein unfolding and stabilization in solution. A lower Tm indicates less stability of a protein in given solution, whereas a higher Tm indicates a better stability of the protein. The Tm of the protein will vary based on the formulation composition which in turn reflects its stability in respective formulation.
  • During long term storage, both aqueous and lyophilized compositions of proteins can lose active protein due to aggregation or degradation. Aggregation of the protein can lead to immunogenicity and is undesirable. Since the concentration of Etanercept used in the composition is high, there is a likely possibility of protein aggregation during long term storage. To improve the stability of the protein either the concentration of the existing excipients can be varied or new excipients can be added to modify the composition.
  • U.S. Pat. No. 5,215,743; U.S. Pat. No. 7,648,702; US application US 20070053906 and WO 2011141926 disclose pharmaceutical compositions comprising aqueous composition of TNF-binding protein comprising a TNF-binding protein, a buffer and an isotonicity agent.

    • DETAIL DESCRIPTION OF INVENTION
  • The invention provides a stable pharmaceutical composition comprising TNFR molecules fused to an Fc portion of a human immunoglobulin (TNFR:Fc fusion protein). More particularly, the invention relates to the stable pharmaceutical composition of etanercept in phosphate-citrate buffer, which displays a lower degradation potential.
  • In an embodiment of the invention, the TNFR:Fc fusion protein is etanercept.
  • It has been reported in U.S. Pat. No. 7,648,702 patent and WO2011141926 application that the pharmaceutical compositions of Etanercept using L-glycine as anti-aggregating agent in phosphate buffer are not stable as compared to the compositions of etanercept with other amino acid such as arginine, proline, lysine, aspartic acid as anti-aggregating agent in phosphate buffer. The WO2011141926 application discloses that the composition comprising Etanercept in phosphate buffer and L-glycine as anti-aggregating agent showed aggregation as well as fragmentation products.
  • While studying the Etanercept compositions in different buffers and using different anti-aggregating agents it was observed that Etanercept composition comprising phosphate-citrate buffer with L-glycine as anti-aggregating agent showed improved stability as compared to Etanercept composition comprising phosphate buffer with L-glycine as anti-aggregating agent at 5° C. and 40° C.
  • As illustrated in the example section, the stability of Etanercept composition essentially consisting of phosphate-citrate buffer in combination with L-glycine as anti-aggregating agent were assessed during a 6 months stability study at 5° C. as well as 2 weeks study at 40° C. (stress conditions stability studies). Compositions comprising the phosphate-citrate buffer system were determined to be superior as compared to composition comprising phosphate buffer system with respect to the % aggregation products and & degradation products as determined by SEC.
  • The stable pharmaceutical composition used herein means that the TNFR:Fc fusion protein exhibits following features:

The % aggregates are less in the Etanercept composition comprising L-glycine as anti-aggregating agent in phosphate-citrate buffer as determined after 2 weeks of storage at 40° C. by SEC.
      • ii. The stable pharmaceutical composition of TNFR:Fc fusion protein in phosphate-citrate buffer exhibits less than 5% high and low molecular weight impurities similar to the innovator composition of etanercept comprising phosphate buffer, arginine and sodium chloride after 2 weeks of storage at 40° C. by SEC.

  • In another embodiment the invention relates to the pharmaceutical composition of Etanercept in phosphate-citrate buffer with other anti-aggregating agents such as urea, HPBCD.
  • After obtaining improved stability of Etanercept composition in phosphate-citrate buffer other anti-aggregating agents from other class of compounds than amino acids were tested.
  • It was observed that Urea and HPBCD also provided stable pharmaceutical compositions of Etanercept in phosphate-citrate buffer. It is understood to mean that etanercept of the pharmaceutical composition does not substantially lose its activity as compared to the composition at the beginning of storage. The term ‘substantially’ refers to not more than 20%, or more preferably 15%, or even more preferably 10%, and most preferably 5% of its activity relative to activity of the composition at the beginning of storage. The pharmaceutical composition of the invention is suitable for long term storage. As used herein, ‘the long term storage’ means that the storage of the pharmaceutical composition is stable for more than a month, preferably more than 6 months or 12 months, more preferably more than 24 months.

  • The active ingredient etanercept, which was used for the described examples, is derived from recombinant DNA technology in CHO cells. The CHO cells were cultured in a fed-batch process. Etanercept was purified from the cell free harvest by standard purification and filtration process including affinity chromatography and further chromatographic and filtration steps. Etanercept was derived from different production batches which was used in the examples, i.e., example 2 and example 5.
    • General Process for Preparation of Stable Pharmaceutical Composition of Etanercept
  • The process for preparing the Etanercept drug substance compositions comprises of 2 steps viz. preparation of formulated bulk and fill finish. The formulated bulk is prepared by diluting the drug substance with the formulation buffer to achieve the desired concentration of drug product. The formulation buffer is prepared by adding required quantity of Trisodium Citrate dihydrate and Sodium dihydrogen phosphate dihydrate to WFI followed by mixing. Further, required quantities of other excipients are added to the above solution and the desired volume is adjusted with WFI after adjustment of pH. The formulation buffer is then aseptically filtered using 0.22μ sterilizing grade PVDF filter. As per the batch calculation, the required quantity of the Etanercept (in same formulation) is aseptically diluted
  • The compositions were analysed by Size Exclusion-High-performance liquid chromatography (SE-HPCL) at different time frames of storage at 5° C., 25° C. and 40° C. SE-HPLC separates the proteins and its related impurities on the basis of their size. Therefore, it is useful to detect aggregation and fragmentation of Etanercept.
  • The examples which follow are illustrative of the invention and are not intended to be limiting.
    • Example 1
