Process Validation

Progress in developing AIDS vaccines is focussing attention on the challenges involved in producing millions of doses for developing nations.

It has been demonstrated that the existing FDA dose content uniformity test has very poor statistical relevance, which has resulted in the acceptance of poor quality batches and the rejection of good quality batches. By using Bayesian Inference, a much improved test has been produced that allows the quality of a batch of drug product to be determined accurately, using a suitable number of samples for the quality of the batch.

The security of documents in the pharmaceutical industry has become a critical issue since the advent of electronic data transfer. Companies in Europe must comply with 21 CFR Part 11 if they sell in the US. The regulations also require that secure, computer-generated, time-stamped audit trails are used to record the date and time of operator entries and actions that create, modify or delete electronic records. In particular, the record change must not obscure previously recorded information.

The European Union is attempting to reform its current business environment in hopes of restoring its role in the lobal R&D sector.

The benefits of using computers and electronic records are proven in most fields of modern-day work, none more so than in laboratories. The opportunities for automation have improved productivity; the computational abilities have increased the accuracy of scientific data and allowed previously difficult or impossible analytical techniques to become routine affairs. This, in turn, has led to huge advances in drug discovery and in the chemical, biochemical and physical analysis of drugs and patients.

A limit test using ion mobility spectrometry (IMS) has the potential to dramatically reduce the time required for cleaning verification and cleaning method development. The traditional approach to cleaning verification, often using HPLC, is relatively resource intensive and can lead to significant delays in reporting results. The main advantage of IMS is that results are seen virtually instantaneously, so any necessary re-measurement can be done very quickly. If the results demonstrate cleanliness, production can resume in a matter of hours not days.

When choosing a CRO, take the time to conduct an in-depth evaluation of each department, paying special attention to the quality and training of its personnel.

Following a step-by-step approach to software development involves planning, analysis, construction, and implementation.

Appropriate sampling procedures, proper preparation, and correct instrumental parameters may yield differing, but correct, results.

Special considerations and cautions must be adhered to when designing virus safety studies and developing appropriate virus contamination control programs.
