Are Your Methods Fit for Purpose?

When addressing the requirements of analytical test procedures, 21 CFR 211.160 states: “Laboratory controls shall include the establishment of scientifically sound and appropriate specifications, standards, sampling plans, and test procedures designed to assure that components, drug product containers, closures, in-process materials, labeling, and drug products conform to appropriate standards of identity, strength, quality, and purity.” 21 CFR […]

PDA/FDA Joint Regulatory Conference 2024 – Day 1

It’s been a pleasure to return to the PDA/FDA’s 2024 Joint Regulatory Conference.  This is the first FDA co-sponsored conference that I’ve attended since my retirement from the Agency in 2023, and it has a bit of a high-school-reunion atmosphere for me.  I’m grateful for the friendships with my FDA colleagues that have extended beyond […]

Does Testing into Compliance Just Apply to Sample Release Test Data?

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 […]

Science versus Compliance?

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 […]

Solving the Puzzle of Single-Use Consumables

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 […]

Antibody Drug Conjugates – Innovation and Challenges

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 […]
