STARTING MATERIALS SELECTION and JUSTIFICATION

by Barbara Unger, GMP Quality Expert, and GMP Regulatory Intelligence Editor-in-Chief

The EMA published a reflection paper on July 3, 2017, that addresses ‘the requirements for selection and justification of starting materials for the manufacture of chemical active substances.’  The intent of the reflection paper, prepared by the Quality Working Party, is to clarify expectations outlined in ICHQ11, Development and Manufacture of Drug Substances (Chemical Entities and Biotechnological / Biological Entities’.  This document covers both human and veterinary medicinal products.  ICH issued a Q&A regarding the selection and justification of starting materials and the most recent draft is dated October 13, 2016. This reflection paper provides additional granularity on expectations of the EU regulatory authority beyond what is found in the ICH Q&A. Taken together, the reflection paper can be summarized as being ‘all about impurities’, both known and unknown. It also targets catalysts, solvents, and regents that are used in manufacture of starting materials and how they are controlled to ensure consistent manufacture of the active substance.

How Does the Government Shutdown Impact FDA Inspections?

Half Open, Half Closed

The government is still shut down, though the FDA is still about half-open.  The question is: which half?

The government shutdown is now on day 9, with no end in sight. Based purely on our 483 sales data in the last 9 days compared to September data, we’re seeing a significant drop. It makes sense that FDA inspections have either slowed down significantly or stopped completely. It was reported earlier this week that 45% of the entire staff would be off. Continue reading

Differences Between Medical Device and Pharmaceutical Clinical Trials – A Primer

Given that the size of the pharmaceutical industry at times overshadows the medical device market, it is no surprise that companies that are just getting started in device development sometimes need clarification about the regulatory implications and practical differences between pharma clinical trials and medical device clinical trials. We’ve put together a basic primer to help guide readers through the most important steps along the medical device regulatory pathway to market, and to explain the disparities between it and the clinical trial process for drug approval.

Taming the Monster – The Economic Benefits of Adaptive Trials

There is no question that pharmaceutical companies large and small are feeling the financial pressures associated with deploying large clinical trials. Traditional trial designs can be overly cumbersome and expensive, particularly when applied to large populations of patients over the course of a lengthy investigation. This inescapable fact has lead many investigators to consider alternative pathways to gathering the safety and efficacy data they need for regulatory purposes, with adaptive trials leading the way.

Tufts Report Reveals Increased Pharma Interest in Adaptive Trials

Improving the efficiency of clinical trials has become one of the most important priorities for pharmaceutical companies around the world. In its annual R&D management report, the Tufts Center for the Study of Drug Development (CSDD) recently estimated the full price of bringing a new drug to market at over $1.3 billion. The report indicated that any areas where R&D costs can be curtailed are extremely interesting to Pharma’s major players. Continue reading

Adaptive Clinical Trials Can Bring You “Beyond the Shadow of a Drought”

R&D production in the pharmaceutical industry has fallen more than 70% over the last 15 years, according to a recently published report, “Beyond the Shadow of a Drought: The need for a new mindset in pharma R&D,” by a group of analysts at the Oliver Wyman consulting firm.  According to this insightful analysis, the underlying causes have not seemed too alarming because pharmaceutical companies still continue to have net incomes of 20% to 30%, and the industry has sustained a 6% annual growth even during the current global economic turmoil.
