In clinical trials, we obsess over how we're getting the investigational drug to the patient.

What about the comparator?
4 Centralized Comparator Sourcing Models To Fortify Supply Chains
<p>A team at Novartis developed models to address the often-overlooked challenge of clinical trial comparator sourcing, a weak link that can derail trials.</p>

Two things are happening at once.
1. More ADCs are moving through pipelines than ever before.
2. More companies are using SUT.
That calls for extra vigilance, especially further downstream.
Those polymer tubes can leach harmful contaminants into exceptionally-low-AET product.

Beginner gardener checking in from the eastern side of Zone 6, and I expect cracking will be especially tough to mitigate this year.
Tomato Tuesday: Concentric fruit cracking can occur due to wide fluctuations in soil moisture, often heavy rain after a dry period. These conditions can cause fruit to expand too quickly for the skin to keep up, leading to fruit cracks. Other causes include temperature variations & poor watering

The biggest impediment to disrupting HCP/mAb binding during protein A chromatography?

Not a lack of science. It might be lousy cooperation.

One scientist tells us that IP considerations complicate a more robust understanding of buffer etc., to mitigate.

FDA named its new AI tool meant to accelerate the review process after a cartoon character who freezes everything she touches. I’m assuming this is a coincidence.

Apple and charging cables convinced me that brand lock-in is the only reason we can't standardize. But maybe that's true only for phones.

For pharma companies standardizing sample containers as they try to automate, Takeda's Adam Wolf offers another reason.

Recertifying new equipment is no fun.

One day, the data auditors will come.

When they do, they won't just be looking at site-wide systems. They might dig into specific applications or even your vendors' systems. 🔍

Dr. Eva Kelly at ERA Sciences shares her list of the top 10 requests data integrity auditors are likely to make.
Count On Data Integrity Auditors Making These 10 Requests
<p>Every audit, however unique, requires confirmation that effective data integrity governance exists, supported by strong SOPs, proper validation, and regulatory adherence.</p>

Digitalization implementation step 1: Get off paper

Chris Grail at Bayer suggests a process-by-process approach asking which ones can move away from paper records.

Inevitably, some processes will remain paper-based, but a digital archiving system can help ensure compliance.

Dozens of factors determine whether allogeneic cell therapy makes it from the donor ➡️ processing facility ➡️ patient.

Temperature control is a big one. Broader use of cryopreservation could clean up many of the issues, says starting material expert Jenny Chain.

Impurities — one of the biggest drawbacks of using biological cell lines to make therapeutic proteins.

With the risk of immunogenicity and even oncogenicity, it's important to know about any host cell proteins or host cell DNA and get it out.

Detecting, characterizing, and quantifying residual DNA in biologics is a common practice, but industry has always lacked a documentary standard — one that will help them meet regulator expectations.

So the USP stepped in to define best practices and put them in a General Chapter.
