Definitions
- the present invention relates broadly to the field of sustained release formulations. More specifically, the invention describes compositions and methods relating to formulating proteins and/or peptides with purified gallic acid esters.
- the gallic acid ester is PentaGalloylGlucose (PGG), where gallic acid is also known as 3,4, 5 trihydroxybenzoic acid and in another example the gallic acid ester is epigallocatechin gallate (EGCG).
- PSG PentaGalloylGlucose
- EGCG epigallocatechin gallate
- sustained release or sustained delivery formulation is desirable to avoid the need for repeated administrations.
- One approach for sustained drug delivery is by microencapsulation, in which the active ingredient is enclosed within a polymeric membrane to produce microparticles. It has been shown that one can encapsulate a biologically active or pharmaceutically active agent within a biocompatible, biodegradable wall forming material such as a polymer, to provide sustained or delayed release. In these methods the agent or drug is typically dissolved, dispersed or emulsified, using stirrers, agitators, or other dynamic mixing techniques, in one or more solvents containing the wall forming material.
- biocompatible and/or biodegradable polymers as carriers for parenteral drug delivery systems is now well established.
- Biocompatible, biodegradable, and relatively inert substances such as poly(lactide) (PLA) or poly(lactide-co-glycolide) (PLGA) microspheres or films containing the active agent to be administered are commonly utilized sustained-release devices (for review, see M. Chasin, Biodegradable polymers for controlled drug delivery. In: J.O. Hollinger Editor, Biomedical Applications of Synthetic Biodegradable Polymers CRC, Boca Raton, FL (1995), pp.
- Another generally desirable quality is biocompatibility: the materials should be tolerated well and biodegradation should produce innocuous compounds that are either eliminated from the body or incorporated in the intermediary metabolism.
- the list of materials used generally for manufacture of parenteral preparations is limited and is shorter still for parenteral protein formulations.
- Another desirable attribute is sufficiently good control of the release of the encapsulated active agent. It is generally important to maintain the concentration of the active agent within an effective window for a time period sufficient to achieve the desired effect and to avoid excessive concentrations, which may lead to side effects or untoward results. It is often difficult to achieve the desired release kinetics with monolithic microparticles as the fraction of the active agent released within the first day after administration is often dependent on the loading level of the drug.
- sustained delivery technologies particularly when applied to the delivery of macromolecules, is that the integrity of the active agent is maintained during manufacture. This is often a difficult challenge as most protein and peptide drugs are dependent on a three dimensional conformation for their bioactivity and that conformation can easily be compromised.
- most of the polymers that are used to manufacture controlled release parenteral preparations are not soluble in water and consequently the protein or peptide is exposed to an organic solvent in the encapsulation step.
- Examples of other undesireable stresses that are associated with manufacturing of controlled release preparations that may compromise the integrity of any particular active agent are high shear forces used to form droplets of the polymer solution in an continuous phase, exposure to polymerization reactions, high temperatures and undesirably low or high pH values.
- sustained release modalities Another desirable attribute of sustained release modalities is that the integrity of the active agent, particularly proteins or peptides, is retained within the microparticles during release. Depending on the chosen duration of release, this period can be from a few days up to several months.
- the acidic microenvironment formed during biodegradation of the polymer may degrade active agents incorporated therein during in vitro and in vivo incubation.
- the prior art describes various sustained delivery compositions and methods for making them, for example, U.S. Pat. Nos. US 5,916,597; 5,019,400; 5,922,253; and 6,531,154.

- a composition e.g., pharmaceutical formulation
- Example 1 provides a description of a preparation of Peptide B-PGG salt (1:1 molar ratio of Peptide B (DOrn Lys Arg Pro Hyp Gly Cpg Ser Dtic Cpg) to PGG).
- a stock solution of PGG was made by dissolving 94 mg of PGG in 2 ml of NaOH solution (concentration of NaOH from 0.10 to 0.20 N) following by filtering it through a 0.2 um filter.
- To a stock solution of PGG (1.56 mL) was added sequentially a solution of 109.4 mg of Peptide B acetate salt in 0.8 mL water with stirring and a precipitate formed. The precipitate was recovered by centrifugation.
- the supernatant was decanted and the precipitate was washed with 0.5 mL water 3 times.
- the precipitate was dried in vacuum at approximately 30-35°C for approximately 20 hours to yield 125 mg (76%).
- the Peptide B-PGG salt was an off- white powder.
- PGG in Example 1 Peptide A was Acetyl Lys Lys Arg Pro Hyp Gly Cpg Ser Dtic
- Example 3 The tables 1 and 2 below list peptide content and solubility of Peptide A
- Example 4 The study of the effect of salt formation pH (i.e. concentration level of NaOH) on the yield, peptide content and solubility of Peptide B-PGG salt was investigated.
- Peptide B-PGG salts at pH 7.0, 7.2, 7.6 and 8.6 were prepared and isolated. Their solubility in water and PBS, and also their peptide content were then determined.

- the PK results showed one- week sustained release for Peptide B/ tannate salt and Peptide B-PGG salt that prepared at pH 7.0.
- Peptide B- PGG salts prepared at pH 7.6 and 8.6 showed shorter release duration (around 2-3 days) compared to salt prepared at pH 7.0 (up to two weeks).
- Example 6 A pure anomer (beta-PGG) and a mixture of anomers (alpha + beta-PGG) of PGG salts of Peptide B (DOrn Lys Arg Pro Hyp Gly Cpg Ser Dtic Cpg) were prepared by a similar method to that described in Example 1. There was no significant difference in the aqueous solubility of these salts. Based on aqueous solubility, it is expected that the in vivo sustained release duration for these salts would be similar.

- PK animal pharmacokinetic
- a stock solution of EGCG (Sigma- Aldrich) was made by dissolving 184 mg of EGCG in 2 ml of 0.2 N NaOH followed by filtering it through a 0.2 um filter.
