S Christians, S Schluender, N D van Treel, M-E Behr-Gross
Molecular-size distribution by size-exclusion chromatography (SEC) [1] is used for the quantification of unwanted aggregated forms in therapeutic polyclonal antibodies, referred to as human immunoglobulins (Ig) in the European Pharmacopoeia. Considering not only the requirements of the monographs for human normal Ig (0338, 0918 and 2788) [2-4], but also the general chapter on chromatographic techniques (2.2.46) [5], several chromatographic column types are allowed for performing this test. Although the EDQM knowledge database gives only 2 examples of suitable columns as a guide for the user, these monographs permit the use of columns with different lengths and diameters, and do not prescribe either particle size or pore size, which are considered key characteristics of SEC columns...

E Terao, A Daas
The European Pharmacopoeia (Ph. Eur.) prescribes the control of the activity of low molecular mass heparins by assays for anti-Xa and anti-IIa activities (monograph 0828), using a reference standard calibrated in International Units (IU). An international collaborative study coded BSP133 was launched in the framework of the Biological Standardisation Programme (BSP) run under the aegis of the Council of Europe and the European Commission to calibrate replacement batches for the dwindling stocks of the Heparin low-molecular-mass for assay Biological Reference Preparation (BRP) batch 8...

The current European Pharmacopoeia (Ph. Eur.) texts for Interferon (IFN)-alfa-2 include a nonspecific photometric protein assay using albumin as calibrator and a highly variable cell-based assay for the potency determination of the protective effects. A request was expressed by the Official Medicines Control Laboratories (OMCLs) for improved methods for the batch control of recombinant interferon alfa-2 bulk and market surveillance testing of finished products, including those formulated with Human Serum Albumin (HSA)...

R Isbrucker, A Daas, L Wagner, A Costanzo
Current regulations for acellular pertussis (aP) vaccines require that they are tested for the presence of residual or reversion-derived pertussis toxin (PTx) activity using the mouse histamine sensitisation test (HIST). Although a CHO cell clustering assay can be used by manufacturers to verify if sufficient inactivation of the substance has occurred in-process, this assay cannot be used at present for the final product due to the presence of aluminium adjuvants which interfere with mammalian cell cultures...

The European Pharmacopoeia (Ph. Eur.) Biological Reference Preparation (BRP) for erythropoietin (EPO) is used as a working standard for potency determination of EPO preparations by in vivo bioassay as prescribed in the Ph. Eur. monograph Erythropoietin concentrated solution (1316). The BRP batch 3 was calibrated in 2006 and its stocks are depleted. The European Directorate for the Quality of Medicines & HealthCare (EDQM) thus initiated a project to calibrate a replacement batch in International Units against the WHO 3(rd) International Standard (IS) for Erythropoietin, recombinant, for bioassay (11/170)...

The current batch of the European Pharmacopoeia (Ph. Eur.) Biological Reference Reagents (BRRs) used for the in vitro potency assay of hepatitis A vaccines (HAV) by ELISA (enzymelinked immunosorbent assay) was established in 2012 for use in conjunction with Ph. Eur. general chapter 2.7.14 Assay of hepatitis A vaccine. It is composed of a coating reagent and a set of detection antibodies. As stocks of the latter are running low, the European Directorate for the Quality of Medicines & HealthCare (EDQM) organised a collaborative study to qualify replacement batches...

Organization (WHO) International Standard (IS) for bleomycin complex A2/B2. Eight laboratories from different countries participated. Potencies of the candidate material were estimated by microbiological assays with sensitive micro-organisms. To ensure continuity between consecutive batches, the 1(st) IS for bleomycin complex A2/B2 was used as a reference. Based on the results of the study, the 2(nd) IS for bleomycin complex A2/B2 was adopted at the meeting of the WHO Expert Committee for Biological Standardization (ECBS) in 2014 with an assigned potency of 12 500 International Units (IU) per vial...

I R Lynch, W Schuh, W Kessler
Raman spectroscopy technique is widely used for the identification and characterisation of materials in the laboratory environment and, increasingly, for off-line, at-line, in-line and online Process Analytical Technologies (PAT) applications. The wide range of currently available Raman technologies had led to the requirement to update the existing General Chapter 2.2.48. The purpose of this reflection paper is to explain the rationale behind the establishment of the new wavenumber scale standards and peak position tolerances resulting from a multi-site, multi-instrument, inter-laboratory study of standards and, in particular, to discuss the results obtained with microscopes (including multi-point calibration) by the PAT Working Party...

J Busch, M Knödler, M Kühn, A Lipinski, B Steinhoff
Raw materials from animal origin are widely used in homoeopathy. Due to the lack of dedicated limits, the quality requirements for herbal drugs of the European Pharmacopoeia (Ph. Eur.) and/or the German Homoeopathic Pharmacopoeia (Homöopathisches Arzneibuch, HAB), including limits for heavy metals such as cadmium, lead and mercury, have been applied. A recent database evaluation shows that for some raw materials of animal origin the Ph. Eur. limits for herbal drugs cannot be met in practice. For this reason proposals for new limits for cadmium, lead and mercury are made based on recent experiences from the companies' daily practice...

In the context of a revision of the European Pharmacopoeia (Ph. Eur.) general monograph Essential oils (2098), the need to include a test for pesticides is being discussed. According to published literature, some oils, mainly those produced by cold pressing (e.g. citrus oils), can contain relevant amounts of pesticide residues, whereas distilled oils showed positive findings in only a few cases. Recent evaluation of a database containing 127 517 sets of data compiled over 8 years, showed positive results in 1 150 cases (0...

The current hepatitis A vaccine (HAV), inactivated, non-adsorbed, European Pharmacopoeia (Ph. Eur.) Biological Reference Preparation (BRP) is used for the in vitro potency assay of HAV as prescribed by the Ph. Eur. general chapter 2.7.14 Assay of hepatitis A vaccine. This reference preparation was calibrated in 2008 through an international collaborative study and was assigned a potency of 12 IU/mL. During use of this BRP it appeared to be inapplicable in certain cases due to a low nominal antigen content. Consequently, the European Directorate for the Quality of Medicines and HealthCare (EDQM) established replacement batches for this BRP, calibrated against the 1(st) WHO International Standard (IS) for HAV (inactivated), using the standard in vitro ELISA (enzyme-linked immunosorbent assay) method validated previously...

The Erythropoietin (EPO) European Pharmacopoeia (Ph. Eur.) Biological Reference Preparation (BRP) batch 3 was calibrated in 2006 by in vivo bioassay and was used as a reference preparation for these assays as well as for the physicochemical methods in the Ph. Eur. monograph Erythropoietin concentrated solution (1316). In order to avoid the frequent replacement of this standard and thus reduce the use of animals, a new EPO Chemical Reference Substance (CRS) was established to be used solely for the physicochemical methods...

A Daas, L Bruckner, C Milne
Rabies is a deadly zoonotic disease. Control of rabies in animals by vaccination is an important strategy to protect humans from infection and control the spread of the disease. Requirements for the quality control of rabies vaccines (inactivated) for veterinary use include an in vivo quantitative potency determination as outlined in the Ph. Eur. monograph 0451. Performance of this assay requires a reference preparation calibrated in International Units (IU). A European Pharmacopeia (Ph. Eur.) Biological Reference Preparation (BRP) for rabies vaccines (inactivated) for veterinary use, calibrated in IU, has been established for this purpose...

The consistency approach for release testing of established vaccines promotes the use of in vitro, analytical, non-animal based systems allowing the monitoring of quality parameters during the whole production process. By using highly sensitive non-animal methods, the consistency approach has the potential to improve the quality of testing and to foster the 3Rs (replacement, refinement and reduction of animal use) for quality control of established vaccines. This concept offers an alternative to the current quality control strategy which often requires large numbers of laboratory animals...

A pharmacopoeial monograph under development for recombinant human erythropoietin (rhEPO) drug substance is likely to contain a specification limit for the proportion of the methionine-oxidised variant. Methionine oxidation has no effect on the folded structure and global thermodynamic stability of rhEPO but can decrease biological activity [1]. We describe here the development of a reference standard, a calibrated mixture of the native and oxidised tryptic peptides which contain methionine-54, and an optimised peptide mapping procedure to support this assay...
