GMPs for HVAC in non-sterile pharma


The World Health Organization has issued a draft guidance, titled “Supplementary guidelines on Good Manufacturing Practices for Heating, Ventilation and Air-Conditioning Systems for Non-Sterile Pharmaceutical Dosage Forms.”

The scope of the document is:

“These guidelines focus primarily on the design and good manufacturing practices (GMP) requirements for HVAC systems for facilities for the manufacture of solid dosage forms. Most of the system design principles for facilities manufacturing solid dosage forms also apply to facilities manufacturing other dosage forms (such as liquids, cream, ointments) and other classes of products including biological products, herbal medicines, complementary medicines and finishing process steps for APIs.”

In terms of the change process, during the consultation on data management, bioequivalence, GMP and medicines’ inspection held in 2015 the possible revision of the guidance for (WHO Technical Report Series, No. 961, Annex 5, 2011) was discussed with the inspectors. It was suggested that in light of the new developments a draft for revision be prepared. This new proposal for revision was drafted based on the feedback received, the new, current trends in engineering and the experience gained during the implementation of this guidance in inspection.

At the same time, the opportunity was used to improve the graphic images and make them more readable in e-version as well as in print.

The document reference is Working document QAS/15.639/Rev.1, and it is dated May 2016.

The document can be found here: WHO

The closing date for comments is July 12, 2016.

WHO Good Data and Record Management Practices

The World Health Organization (WHO) has issued a draft guidance document titled “Good Data and Record Management Practices.” The document is out for public comment.

Medicines regulatory systems worldwide have always depended upon the knowledge of organizations that develop, manufacture and package, test, distribute and monitor pharmaceutical products. Implicit in the assessment and review process is a trust between the regulator and the regulated that the information submitted in dossiers and used in day-to-day decision-making is comprehensive, complete and reliable. Data on which these decisions are based should therefore be complete as well as being accurate, legible, contemporaneous, original and attributable; commonly referred to as “ALCOA”.

The draft discusses the controls necessary for good data management, which include:

A quality risk management approach that effectively assures patient safety and product quality and validity of data by ensuring that management aligns expectations with actual process capabilities. Management should govern good data management by first setting realistic and achievable expectations for the true and current capabilities of a process, method, environment, personnel, technologies, etc.;

Management should continuously monitor process capabilities and allocate the necessary resources to ensure and enhance infrastructure, as required (for example, to continuously improve processes and methods; to ensure adequate design and maintenance of buildings, facilities, equipment and systems; to ensure adequate reliable power and water; to provide necessary training for personnel; to allocate the necessary resources to the oversight of contract sites and suppliers to ensure adequate quality standards are met, etc.). Active engagement by management in this manner remediates and reduces pressures and possible sources of error that may increase data integrity risks;

Adoption of a quality culture within the company that encourages personnel to be transparent in failures so that management has an accurate understanding of risks and can then provide the necessary resources to achieve expectations and data quality standards;


Mapping of data processes and application of modern quality risk management and sound scientific principles across the data life cycle;

Modernization of the understanding of all site personnel in the application of good documentation practices to ensure that the GxP principles of ALCOA are understood and applied to electronic data in the same manner that has historically been applied to paper records;

Implementation and confirmation during validation of computerized systems that all necessary controls for good documentation practices for electronic data are in place and that the probability of the occurrence of errors in the data is minimized;

Training of personnel who use computerized systems and review electronic data in basic understanding of how computerized systems work and how to efficiently review the electronic data and metadata, such as audit trails;

Definition and management of appropriate roles and responsibilities for quality agreements and contracts entered into by contract givers and contract acceptors, including the need for risk-based monitoring of data generated and managed by the contract acceptor on behalf of the contract giver;

Modernization of quality assurance inspection techniques and gathering of quality metrics to efficiently and effectively identify risks and opportunities to improve data processes.

WHO GMP for Biologicals (Draft) - Invitation for Comments


The WHO GMP for biological products (proposed to replacement of TRS 822 annex 1 has been submitted to Expert Committee on Biological Standardization and accepted as a BS document WHO/BS/2015.2253 and posted on WHO biological website to invite public comments. A Comment Form is downloadable from the website below to the document.

Manufacturing procedures within the scope of these guidelines include:

  • growth of strains of microorganisms and eukaryotic cells; 
  • extraction of substances from biological tissues, including human, animal and plant tissues, and fungi; recombinant DNA (rDNA) techniques; 
  • hybridoma techniques; 
  • propagation of microorganisms in embryos or animals. 
The introduction states:

"This document is intended to serve as a basis for establishing national guidelines for GMP. The main principles and recommendations for manufacturing biological products are provided. If a national regulatory authority (NRA) so desires, these  guidelines may be adopted as definitive national requirements. It is possible that 25 modifications to this document may be justified due to the risk benefit balance and legal considerations in each authority. In such cases, it is recommended that any  modification to the principles and technical specifications of these guidelines should be made only on the condition that the modifications ensure product quality, safety  and efficacy that are at least equivalent to what is recommended in these guidelines."

Here is a direct link to the document.

Drug resistant TB cases are 'underestimated'

The World Health Organization has estimated that at least three-quarters of drug-resistant tuberculosis cases have not been detected.
The news comes from the World Health Organization's (WHO) latest Global Tuberculosis Report. The report suggests that less than 25 percent of drug resistant cases of tuberculosis have been detected in 2012. This prevalence means that scientists are are still very far away from making real progress against this killer disease.
Tuberculosis (TB) is a common, and in many cases lethal, infectious disease caused by various strains of mycobacteria, usually Mycobacterium tuberculosis. Tuberculosis may infect any part of the body, but most commonly occurs in the lungs. Globally, tuberculosis is the second most common cause of death from infectious disease (after those due to HIV/AIDS).
Commenting on the report, Mario Raviglione, director of the WHO Global TB program, said to Nature magazine: "the debt toll of tuberculosis, a disease that is preventable and curable, is far too high."
There is a positive that can be drawn from the report: the rate of new tuberculosis (TB) cases and the percentage of people who die from the disease has continued to decline.

WHO issues guidelines on non-sterile process validation


The World Health Organisation (WHO) has issued guidelines for the revision of the supplementary guidelines on good manufacturing practices: non-sterile process validation. The closing date for comments is May 24th, 2013.

The introduction to the document states:

"This guideline allows for different approaches in process validation. The principles described in this guideline are applicable to non-sterile finished pharmaceutical dosage forms. Thorough knowledge of product and process development studies; previous manufacturing experience; and quality risk management (QRM) principles are essential in the all approaches to process validation as the focus is now on the life-cycle approach. The life-cycle approach links product and process development, validation of the commercial manufacturing process and maintenance of the process during routine commercial production."

In the document it is explained that manufacturers should plan towards implementing the new approach in process validation that should consist of three phases in the product life-cycle.
  • Phase I. Process design
  • Phase II. Qualification and process verificatio
  • Phase IIA. Qualificatio
  • Phase IIB. Continuous process performance verification
  • Phase III. Continued process verification 
The document is designed to form part of the supplementary guidelines on good manufacturing practices: validation. In: WHO Expert Committee on Specifications for Pharmaceutical Preparations. Fortieth report. Geneva, World Health Organization. WHO Technical Report Series, No. 937 (Annex 5), 2006.
