As Bob has previously blogged on the highlights from AAM day by day, let me take a moment to dive a bit deeper into one of the sessions. As an attendee of this meeting for several years, one of the best things about AAM’s GRx+Biosims is that sessions at this meeting often offer a mix […]
It was just last week, on October 7, 2024, when we published a blog (here) titled FDA Planned OTC Monograph Actions. That post outlined the OTC monograph issues that the Agency was planning to address over the next three years. Well, obviously, the FDA must have had its eyes set on beginning efforts on the issue […]
The FDA has updated the original nitrosamine impurity guidance after publication last year of Recommended Acceptable Intake Limits for Nitrosamine Drug Substance-Related Impurities (NDSRIs) (here), also known as the RAIL guidance, caused a few disconnects between the two guidances. Now that we’ve all had more time to carefully read and absorb the updates in the […]
U.S. and EU efforts to manage supply chain shortages are slowly converging; however, the political winds in the Rest of World (ROW) may be diluting required oversight. Both the U.S. (Risk Management Plans to Mitigate the Potential for Drug Shortages | FDA) and EU (Shortage Prevention Plan (SPP) – template (europa.eu)) have published either a […]
The WHO has a draft July 2013 guidance document titled “Deviation Handling and Quality Risk Management” that addresses the concept that not all Quality Events are equivalent and provides consideration for the classification of events. For example, an incident would be an event that does not: “…affect a product attribute, manufacturing operational parameter or the […]
Today, the FDA issued a new immediately effective guidance entitled “Control of Nitrosamine Impurities in Human Drugs” that replaces the initial guidance by the same name that was issued on February 24, 2021. The new guidance can be found here. The industry has been awaiting the issuance of this revised guidance and the “FDA made […]
In the world of subjective tests, it can be difficult to investigate when things go wrong or when analysts have a different view of an appearance test. For example: The titrimetric test has an endpoint of blue-green, according to USP. The new analyst obtains an OOS result. The experienced analyst says the endpoint color should […]
Working in the pharmaceutical industry, you can sometimes hear science and compliance talked about as if they are separate and unrelated. Two examples of what can be heard: “Oh well, that is more of a compliance risk than a scientific concern.” “You need to consider the compliance aspect of that change and then the scientific […]
Although the FDA’s regulatory requirements for acceptance of vendor test results in lieu of testing is clearly specified in 21 CFR 211.84 for incoming raw materials and container closures, the FDA has not put forth specific regulations for the acceptance of single-use consumables. Biologics manufacturers may use dozens or even hundreds of different single-use consumables […]
The development of antibody-drug conjugates (ADCs) typically involves using monoclonal antibodies (mAbs) “linked” to a cytotoxic drug and used as a specific targeting mechanism to deliver highly potent drugs to a surface antigen present only on tumor cells. Think of it as the biologics version of a smart bomb, with a targeting system able to […]
