PEGylation

. 1. Poly(ethylene glycol) –the Pioneer in Polymer Therapeutics

1.1. Background

PEGylated proteins were the first polymer therapeutic drugs reaching market approval around 1990. PEGs show a spectrum of unique physical and chemical properties which have been described in literature extensively. Here are summarized the most common ones:

PEG fragments can be attached to many different positions in a protein. Amino groups of any solvent accessible lysines as well as the N-termini are the most prominent candidates for conjugation together with thiol functions of cysteines. The C-terminus or carboxylic groups from aspartic acid and glutamic acid are also possible for conjugation, however, are less frequently used.

• PEG can serve as spacer or cross linker between two moieties.

• PEG provides high solubility and does not contain charged side chains.

PEG is FDA-approved for internal application, is non-toxic, lacks T-cell epitopes, and shows no signs of immunogenicity in most animal experiments.

• PEG derivatives are available from uniform molecules with short chain lengths (down to two ethylene oxide units only), to long disperse constructs, allowing regio-specific chemical conjugation with small molecules, proteins, peptides, and biopharmaceuticals through their broad variety of available terminal chemical groups.

Summary of chemical and physical properties of PEGs:

• Good solubility in BOTH hydrophilic AND hydrophobic solvents as water, toluene, methylene chloride, and many other organic solvents. Insoluble in diethyl ether, hexane, ethylene glycol.

• Insoluble in water at elevated temperature.

• The solubility is influenced by formed derivatives.

• Highly mobile in water with high exclusion volume; large hydrodynamic radius.

• Complex formation with metal cations is possible. Can be used to precipitate proteins and nucleic acids. Form two-phase systems with aqueous solutions of other polymers. Non-toxic and FDA-approved for use in drug products.

PEGylation of biopharmaceuticals or small molecules brings the following effects:

• Improves solubility of conjugated molecules. Renders proteins non-immunogenic and tolerogenic. Reduces the rate of renal clearance through the kidney and alters pharmacokinetics. Alters electroosmotic flow.

Increases cell permeability.

The increasing use of PEG and PEGylated products in pharmaceutical research and on the market provides new insights into the underlying mechanism of their properties. PEGs are e.g. not biodegradable in the human body, so it can lead to certain accumulation in cytoplasmic vacuoles, particularly at high doses and especially in kidneys:

Fig. 1: (Left) PEG immunoreactivity in kidney from rats given 100 mg/kg 10kPEG IV. There is variable but diffuse PEG staining in tubular epithelial cells throughout the renal cortex. PEG staining is not associated with epithelial cell vacuolation (Magnification 230x).

(Right) Cytoplasmic vacuoles (arrows) are associated with variable levels of PEG immunoreactivity in the kidney (300x) in rats given 100 mg/kg 40kPEG. The cortical tubule and choroid plexus had both darkly stained and clear vacuoles (pictures adapted from Rudman et al . 2013).

Despite all sporadic drawbacks as mentioned above, PEG, nevertheless, is still the most widely applied polymer in drug delivery.

This brochure displays a portfolio of a thousand different PEG derivatives with a length ranging from only 2 ethylene glycol units (with a molecular weight around 100 g/mol) up to long chain PEGs of molecular weights beyond 20,000 g/mol. Further to this standard portfolio, we can produce also customized PEG variants according to your personal needs.

1.2. Principles of Polymer Therapeutics and Drug Delivery Systems

Modern drug development technologies such as combinatorial chemistry and automated high-throughput screening have led to the identification of numerous potential new active pharmaceutical ingredients (APls). However, many of those promising new molecules never reach market approval because they are not sufficiently soluble, cannot reach the desired target, are attacked by the immune system, are degraded by endogenous enzymes, or suffer from rapid renal clearance. To overcome these restrictions, first attempts with polymers were made already in the 1960s - either by attaching the therapeutic agent covalently to a polymer or by entrapping it non-covalently in a polymer nanoparticle.

The first polymer-drug conjugates that showed promising results contained poly(ethylene glycol) “PEG”, and until today, PEG is the most widely used gold standard for stealth polymers in the continuously emerging field of polymer-based drug delivery. The pharmacological effects of PEG and many other first generation polymer attachments are mainly of physical nature:

Solubilizing

PEG and many other polymers are very hygroscopic and hydrophilic and thus improve the plasma solubility of hydrophobic pharmaceuticals. By this, higher therapeutic concentrations in plasma and tissues are accessible.

Preventing Degradation and Reducing lmmunogenicity

Polymer chains are covering the surface of a pharmaceutical, thus efficiently shielding it against attacks by the immune system or degrading enzymes such as proteases. The polymeric shield has characteristics rather like a solvent than like a protein. This prevents uptake by the macrophage system. Recognition by the immune system (antibodies, proteases, and other degradation enzymes etc.) is significantly reduced. The drug stays intact and is not destroyed (degraded or metabolized) during its presence in the body and journey through the physiological system.

Preventing Excretion

Hygroscopic polymers are surrounded by a large solvating sphere of water molecules. The hydrodynamic radius of the polymer-drug conjugate can be increased to a size larger than the diameter of the kidney’s glomerular capillaries (6 to 12 nm). Retarded renal filtration prolongs plasma half-life of the biological drug by means of a purely biophysical size effect, without any receptor interactions that may influence pharmacodynamics or lead to side effects.

Fig. 2: PEGylation increases the hydrodynamic radius and aqueous solubility of proteins. Hence, the pharmacokinetic properties of a PEGylated drug in contrast to a non-PEGylated one are significantly different. The half-time in plasma is, therefore, significantly longer.

1.3. Chemical and Physical Properties of PEG Polymers

The most important parameter describing a polymer is the degree of polymerization “DP”. DP describes the number of monomeric units in a polymer molecule. If a polymer consists of only one single molecular weight species (a defined number n of repeating units), the polymer is called “homopolymer” or “uniform”. A common term previously used is “monodisperse”. Most polymers consist of a range of species with an average mass and a distribution of n around a mean value. These polymers are referred to as “polydisperse”, “disperse”, or “non-uniform”. If the polymer is polydisperse, its mass spectrum will show a range of different molecular weights as shown in a typical mass spectrum Fig. 4:

Fig. 3: Structure example of a PEG with DP = n. Fig. 4: Mass spectrum of a PEG showing the typical signals with a difference of m/z = 44.

A measure of the distribution of molecular weights in a polymer is given by the Polydispersity or simply Dispersity Đ, which is defined as the ratio between the weight average molecular weight M°w and the number average molecular weight M°n :

The weight average M°w does not “count” species just by their number but considers the total weight of each species and is therefore a much more realistic indicator of the gross mechanical properties of a polymer. In case of a homopolymer with a defined chain length, M°w is equal to M°n , thus the dispersity Đ equals 1.00 and the compound is referred to as uniform. Whenever there is a distribution of molecular weights, the weight average M°w is always higher than the number average M°n , and consequently the dispersity Đ is greater than 1.00. The dispersity of polymers typically used in polymer therapeutics ranges between 1.01 and 1.20.

Generally, a rather low Đ value close to 1.00 is aspired as it is an indication for a well-controlled and mastered polymerization process. However, such a narrow weight distribution is not always of advantage in practice. For the formation of some nanostructures, it may be necessary to have a rather broad distribution of molecule sizes, resulting in a rather high dispersity Đ. For example, some polymers can form spheric nanoparticles when used at high dispersity but will form fibrils if used in a dispersity close to 1.00. In other applications, it may be necessary to have material with very low dispersity. In order to reach reproducible results, it is crucial to work with highly pure polymers of good batchtobatch reproducibility.

1.4. Quality Parameters of PEG Polymers

For a small molecule, typically a rather limited set of analytical parameters (for example: purity by HPLC, identity by NMR or mass spectroscopy, and residual solvents content) is sufficient to describe the quality of each material batch.

For a polymer, a much more sophisticated analysis is necessary to describe the quality of the material comprehensively. Depending on the application’s needs and on authorities’ demand, the certificate of analysis for a therapeutic polymer may contain dozens of different analytical parameters.

The development of analytical methods and processes requires an extensive understanding of the polymer itself and about the expressiveness of the various analytical parameters.

For our therapeutic polymers, the analytical laboratory is staffed by highly-qualified personnel who use equipment specially focused, but not limited, to the quality control of polymers. All instruments are qualified, and the validated analysis conforms to international and European standards.

1.5. Modes of Polymer Application

During the last decades, PEG and several other polymers have entered the field of drug delivery: natural and nonnatural ones, biodegradable and non-degradable ones, such as: proteins, poly(amino acids), peptides, peptoids, polysaccharides, modified cellulose derivatives, polyesters, polyamides, polyanhydrides, polyphosphonates, polyacrylates, and many more. Independent of their chemical nature, polymer therapeutics can be classified by their mode of application:

Polymeric Drugs

The polymer itself is the active pharmaceutical ingredient. One market approved example is Copaxone®, a random copolymer of Alanine, Glutamate, Lysine, and Tyrosine for the treatment of multiple sclerosis.

Polymer-Drug Conjugates

Here, a polymer backbone carries one or several active moieties, as for example in Opaxio®, a poly(glutamic acid)-Paclitaxel conjugate for cancer treatment.

Polymer-Protein Conjugates

One or several polymer chains are attached to a protein, peptide, or antibody, as for example in Pegasys®, a PEGylated Interferon alpha 2a for the treatment of Hepatitis C.

Polymer-Based Hydrogels

Some polymers can be used to form hydrogels of defined pore size, water content, life-time and many more properties. Such hydrogels can be used to cage active ingredients, keep them perfectly hydrated, regulate their skin or tissue permeation, dose their release, and thus optimize their function. Often, such hydrogels are used in cosmetic applications.

Polymer-Based Nanoparticles

These nanoparticles are typically formed by a mixture of different lipid and polymer types and can form - among others - micelles (consisting of a monolayer), liposomes (consisting of a bilayer), or lipid nanoparticles “LNPs” (composed of multiple lipid layers as well as microdomains of lipid and nucleic acid). Examples for such nanoparticles are the latest mRNA-based SARS-CoV2 vaccines from Moderna, BioNTech/Pfizer or CureVac.

These different application modes already point out that polymer therapeutics offer far more possibilities than the simple shielding and enlarging effects previously mentioned.

Concentration Effect

A large polyvalent polymeric carrier can enable the attachment of several active moieties on one macromolecule. If, for example, the pharmaceutical role of the active ingredient is to bind and block a surface receptor, the presence of several binding ligands will significantly increase the binding energy and thus lead to a more efficient receptor binding. As non-covalent receptor binding is a dynamic equilibrium of association and dissociation, a released single small molecule can easily be departed by the bloodstream and thus be prevented from re-binding. However, if it is part of a polymer which binds to the cell surface by several other of its binding moieties, it will not diffuse away, but will re-bind quickly to any free receptor on the surface.

Targeting Effect

A polymer carrier can be equipped both with a targeting moiety and with active molecules. For example, an RGD peptide can guide the polymer to cancer cells. After internalization, several bound cytotoxic molecules such as Paclitaxel can be released to kill the abnormal cell.

Shuttle Effect

An intelligent design of the drug delivery system can help transporting a payload to destinations where it could not go without the polymer’s help. There are systems that help crossing the skin barrier, some poly(amino acids) can help small molecules to cross cell membranes, LNPs as nonviral vectors can even transport DNA and RNA into living cells, and other polymers help crossing the blood-brain-barrier. back to content arrow-up

PEGylation

Combination Effect

Some cells develop resistance to a pharmaceutical treatment. If this happens, the treatment must be changed to a new strategy and cells may subsequently also develop resistance to the altered therapy. However, in polymer therapeutics, the two different active ingredients can be attached to one polymer. The simultaneous delivery of two different active cargos strongly suppresses the formation of resistances, because cells would have to develop both resistances at the same time, which is almost impossible.
