Quality/GMPs

We often assume we know what success looks like for our partner, but we never ask them, or take the time to write it down.

The first part of this article, published in the September 2006 issue, discussed general strategies for validation extensions to other test method components, laboratories and even different test methods.1This second part provides practical tips on how to maintain test method suitability long after the formal completion of analytical method validation (AMV) studies.

It is important to ensure that flow decay during processing is comparable to that observed during retention studies.

While not yet finalized and adopted, ICH Q10 represents some of the most current thinking with respect to pharmaceuticals manufacturing and control.

Established, fully validated methodology and SOPs are required prior to initiation of any training activities.

Development reports document process development and support the design of validation experiments, yet in many firms training is not provided nor are expectations established. This article describes how project managers can help scientists master the art of report-writing.

SOPs are written job aids that detail the procedure of how to do a specific job task correctly.

The concept of design space has started a minor revolution in our industry.

Reserve samples of test and control articles must be retained for at least one stability time point after the completion of the study.

The challenge is to determine the optimal frequency for preventive maintenance and the optimal frequency and tolerances for calibration readings.

Taking a purist stance is always tempting. It can, however, have unintended consequences.

Companies faced with real or threatened FDA sanctions are usually least prepared to react effectively.

Better supplier management can begin in parallel to production-related improvements.

Increasingly, pharmaceutical companies have recognized that software development is not their core competency.

Good risk management tools dictate how much assay performance characteristics can deviate from ideal.

There is growing support for new partnership arrangements that seek to expand drug research by reducing the financial risk for manufacturers.

Nothing beats a good dictionary. It can clarify doubts, settle an argument, or prompt exploration into new areas of learning.

Wyeth today relies on biotech product revenue to drive approximately 25% of its revenues.

Understand your company's requirements, define responsibilities,and manage your team effectively.

FDA did not gain any real teeth for regulating unsafe and ineffective products until a national health disaster in 1937 roused a public outcry.

Congress is not considering legislation that would expand FDA authority to regulate biologics.

Case studies were run to test Process Analytical Technology applications for protein refolding, diafiltration, and cation exchange chromatography. It is shown that it is feasible to design control schemes that rely on measurement of product quality attributes and thereby enable real-time decisions.

Federal regulations are broad and open to interpretation. Most have not caught up with advancements in technology.

A novel calibration approach was developed that not only calibrates the X-axis, but also calibrates the peak shape.
