Regulatory aspects of therapeutic proteins

He emphasized that general regulatory expectations are set forth in various regulatory guidance documents (e.g., ICH Q6B, Q2(R1), and Q7A) for reference standards of biologics. Those documents should be considered during development, licensure, and application of reference standards for therapeutic proteins Therapeutic proteins include different molecules ranging from peptides to large proteins such as coagulation factors. Historically, the pharmacokinetic evaluation of such products has suffered essentially from limitations in the assay methodology and the derived pharmacokinetic parameters, limiting the usefulness of such studies PROTEIN THERAPEUTICS  This therapeutic approach in treating diseases using proteins and peptides is termed protein therapeutics.  Protein therapy is similar to gene therapy, but unlike gene therapy, protein therapy delivers protein to the body in specific amounts (as would be ordinarily present), to help repair illness, treat pain or remake structures.  Introduced in 1920's Human insulin is considered to be the first therapeutic protein

Biotherapeutic proteins (which may be natural or recombinant products) are complex with respect to primary, secondary, and tertiary structure as well as posttranslational modifications. Such attributes vary depending on the manufacturing processes and thereby may affect a molecule's biological activity. For such products, biologica Assessment of immunogenicity of therapeutic proteins is a required aspect of regulatory filings for a licensing application and for the safe and efficacious use of these compounds. A systematic strategy and well-defined criteria for measuring anti-drug antibodies (ADA) have been established, to a large extent, through coordinated efforts Therapeutic proteins Therapeutic proteins represent an area under rapid development. In fact, biologics globally dominate clinical trials and registrations of new pharmaceutical drugs. Large investments for research and development are currently being made in many countries relationship for glycosylated therapeutic proteins and develop a decision matrix to determine the relevance of glycosylation on biologic properties (potency, clearance, immunogenicity) of a given therapeutic.

The inhibitor of differentiation (ID) proteins are helix-loop-helix transcriptional repressors with established roles in stem cell self-renewal, lineage commitment, and niche interactions. While deregulated expression of ID proteins in cancer was identified more than a decade ago, emerging evidence has revealed a central role for ID proteins in neoplastic progression of multiple tumor types. A totally different aspect to consider when developing a therapeutic protein is the feasibility of oral administration of proteins encapsulated in plant cells. Specifically, carrot cells containing recombinant human β‐glucocerebrosidase for ERT of Gaucher disease can be used as an oral delivery system and are a feasible alternative to intravenous administration of ERT for GD (Shaaltiel et. therapeutic protein Introduction Recombinant therapeutic proteins, particularly monoclonal anti-bodies (mAbs), have become a major class of biotherapeutics to treat various human diseases.1,2 To date, more than 90 mAbs have been approved.3 To ensure product quality, attributes tha Such proteins are likely to be required for the proper functioning of the regulatory proteins in viral replication and may provide additional targets for therapeutic intervention.

Analysis of regulatory guidance on antidrug antibody

Neutralizing antibodies (NAbs) bind to sites in therapeutic proteins in such a way that they directly impair or abrogate the biological functions of therapeutic proteins [6, 9]. NAb responses have the potential to cause negative clinical consequences by neutralizing the therapeutic product and therefore reducing efficacy, as has been seen with factor VIII or streptokinase [ 10 , 11 ] Recent advances in high resolution mass spectrometry (MS) instrumentation and semi-automated software have led to a push toward the use of MS-based methods for quality control (QC) testing of therapeutic proteins in a cGMP environment. The approach that is most commonly being proposed for this purpose is known as the multi-attribute method (MAM). MAM is a promising approach that provides some.
