Pew Prescription Project: After Heparin

2 Comments

Last week the Pew Prescription Project, an arm of the Pew Charitable Trust, released a report on the risks of substandard and counterfeit drugs.  This is a meticulously researched report that will likely be used by legislators and regulators to better understand the problems and potential solutions of U.S. pharmaceutical supply chain security.  For this reason it is a must-read for anyone interested in the topics that RxTrace routinely explores.  You can get a copy of the full report PDF, view the associated webcast and graphic here:  After Heparin: Protecting Americans from the Risks of Substandard and Counterfeit Drugs.  I’ll have more to say about the webcast in a subsequent essay.

According to the “Introduction and Background”,

“The U.S. Congress, the U.S. Food and Drug Administration (FDA), the pharmaceutical industry and other organizations have renewed their commitments to remedy existing weaknesses.  This white paper seeks to inform these efforts by presenting a holistic picture of the pharmaceutical supply chain and its problems (illustrated by case studies), and to propose a set of meaningful reforms that will better protect patients.”

The report is 77 pages of text with 24 additional pages of references.  The text is peppered with numbered references for those who want more details on a particular topic.

There are three Chapters.

  1. Pharmaceutical Manufacturing:  Globalization and Quality Management
  2. Barriers to FDA Oversight
  3. Pharmaceutical Distribution

Chapter 1 contains Continue reading Pew Prescription Project: After Heparin →

SNI

SNI’s Are Not Enough In a Plateau-Based Supply Chain Security Approach

I recently published an essay on RxTrace called “Plateaus of Pharma Supply Chain Security” in which I proposed that a better timeline for the introduction of technology to secure the U.S. pharmaceutical supply chain was one based on plateaus.  Each succeeding plateau would add the adoption of new technology and/or data communications among the participants in the supply chain with the intent of elevating the security over the previous plateau.

In that essay I included illustrative dates for each of the four plateaus that I offered as an example of the concept, but you could easily imagine the overall program having open-ended dates that would allow the supply chain to adopt one plateau at a time and move to the next plateau only if/when a security problem is discovered at the current plateau.  That is, jump to the next plateau only when necessary.  Taking this approach, you may never actually need to get to the later plateaus.

For example, imagine that the first plateau were for manufacturers to serialize all drugs at the pharmacy-saleable package level (what I normally call “unit-level”) with an FDA Standardized Numeric Identifier (SNI) and all supply chain owners of drugs were to read the SNI’s and simply keep records of who they bought them from and who they sold them to.

With no data communications between trading partners that includes the SNI’s it might seem that little
security has been gained over what is done today.  But this small step (“small” compared to a full pedigree or track & trace system) would allow criminal Continue reading SNI’s Are Not Enough In a Plateau-Based Supply Chain Security Approach →

Illegitimate Drugs In The U.S. Supply Chain: Needle In A Haystack

1 Comment

West-African countries have been under attack by drug counterfeiting criminals for decades with little resistance until the last one.  The result, in 2002 Mohammed Yaro Budah, then president of the Pharmaceutical Society of Nigeria, estimated that 70% of the drugs in Nigeria were fake or substandard.  That’s an incredible figure, but starting around that time the Nigerian National Agency for Food and Drug Administration and Control (NAFDAC) under the direction of Professor Dora Akunyili began fighting back.

Initially they focused on inspecting drug imports at the Nigerian ports and airports and they were able to bring the percentage of fake or substandard drugs to come down considerably.  More recently they have begun employing a number of Raman Spectroscopy-based devices called TruScan (recently acquired by Thermo Scientific) to inspect drugs and anti-viral medicines being sold in pharmacies during “unscheduled” visits.

Even more recently, a number of pharma manufacturers have begun to add low cost scratch-off stickers to the drugs sold in Nigeria that cover a random number that can be scratched off and checked for authenticity by patients and healthcare professionals using SMS text message-based technology from Sproxil.  The service was launched in 2010 on a single product but that number is growing quickly as a number of large U.S.-based drug companies add the scratch-off stickers to their products.  The service is sponsored by NAFDAC.

WOULD THESE TECHNOLOGIES WORK IN THE U.S.?

That is, would these technologies help to reduce the number of illegitimate drugs in the U.S. supply chain? I believe that the answer is Continue reading Illegitimate Drugs In The U.S. Supply Chain: Needle In A Haystack →

Industry Adoption

Plateaus of Pharma Supply Chain Security

6 Comments

One of the most recent improvements that California made to their drug pedigree law was to spread out the compliance dates by supply chain segment.   Previously, all segments had to comply with the regulation by January 2011.   Now drug manufacturers will need to comply with half of the products (or sales) by January 2015 and the remainder one year later, distributors must comply by mid-2016 and the pharmacies by mid-2017.   As I understand it, this spread was intended to help the industry fully prepare for the new requirements in their businesses.   Companies would now have time to adjust to the changes implemented by their upstream trading partners according to their earlier deadlines.

This staggered start pleased a lot of people—particularly distributors and pharmacies.   However, to me, the staggered start of the current California regulation doesn’t address the issue of complexity very well and a different kind of ramp up to full operation would be more practical and have better odds for success.

I discussed complexity in my last essay, “U.S. Pharma Supply Chain Complexity”.   I tried to show what it is about the supply chain that leads to difficulty in the setup and execution of a drug pedigree system.   On its own, the U.S. pharma supply chain is naturally complex.   A truly workable and protective pedigree system needs to deal with that natural complexity without exploding in its own complexity and cost.   As I pointed out in that essay, the problem with the more popular pedigree models (like DPMS and the various distributed pedigree models) is the large number of the point-to-point data connections that are necessary to reflect the natural complexity of the supply chain.   That adds a lot of complexity.

THE PLATEAUS OF SECURITY

No matter which model the industry implements, starting it up will have its own complexities.   In my view, regulators and industry should Continue reading Plateaus of Pharma Supply Chain Security →

The debate over pedigree regulatory models in the U.S. pharmaceutical supply chain often centers around how much data for each package of drugs needs to be moved between trading partners as those drugs move down the supply chain from the manufacturer to distributor(s) and ultimately to the pharmacy.  The ideal model would minimize the amount of data moved yet always allow each member of the supply chain to check the prior history—the pedigree—of the drugs they are about to buy.

At a superficial level this appears to be all you need to do, but when you take a closer at the details of how the supply chain actually works in the U.S. you will see that there are other characteristics besides data volume per package that need to be considered.

FOUR VIEWS OF THE U.S. SUPPLY CHAIN

In the debates and discussions over pedigree regulatory models we are used to seeing a view of the supply chain that shows one manufacturer, one distributor and one pharmacy.  That view masks so much important complexity that if we were to select a regulatory model or solution based on that view it would be far from ideal.

Here is a view of the supply chain where the vertical scale shows something closer to the true proportions between those three segments. Continue reading U.S. Pharma Supply Chain Complexity →

The Viability of Global Track & Trace Models

3 Comments

At the end of my last essay I said I had recently concluded that the jump to a fully automated pharma supply chain upstream visibility system is too big and complex to be achievable by every company in the U.S. supply chain by the California dates.  I want to explain that statement in a future essay (soon), but before I do I want to explore some of the track and trace models that are being considered by both GS1 and the FDA.  I particularly want to look at the viability of each model because I think we will find that some just aren’t (viable), and that will help narrow the search.

I’ll look at the three basic models that the FDA mentioned in their recent workshop:  Centralized, Semi-Centralized and Distributed (or Decentralized as the FDA called it).  There are others, but it seems that they can all be either based on, or reduced to, one of these three basic models.

In this essay I am looking at track & trace models from a global viewpoint, which is something that GS1 is doing but the FDA may not.  Attacks on the pharma supply chain are a global problem and global problems demand global solutions or gaps will be left for criminals to exploit.

GS1’s goal is to develop standards that apply globally as much as possible and the FDA will likely find that Continue reading The Viability of Global Track & Trace Models →

Reliance on Trust in the U.S. Pharma Supply Chain

7 Comments

Trust plays a big role in today’s U.S. pharmaceutical supply chain.  Patients trust that their doctors know what they are doing when they prescribe a medicine and they trust their pharmacist to fill their prescriptions with real medicines that were:

  • manufactured to tight quality specifications,
  • are well within the expiration date,
  • have not been tampered with,
  • have always been kept within recommended environmental tolerances,
  • and have been in the control of companies who have a strong interest in supply chain integrity and in the safety of the drugs within the supply chain.

When we receive our little amber bottles of repackaged drugs from our pharmacist, we aren’t given any way to check on any of those things ourselves.  We trust that the pharmacy has done something to ensure all that.  And fortunately in the U.S., we are almost always justified in that trust.  We enjoy the safest supply chain in the world.

A WHOLE LOT O’ TRUSTIN’ GOIN’ ON

But, now if the pharmacy doesn’t get the drugs directly from the manufacturer, they trust that their wholesaler will supply them with drugs that have those characteristics too.  And if the pharmacy’s wholesaler doesn’t get the drugs directly from the manufacturer, they trust that their wholesaler’s wholesaler provides them with drugs like that too.  And if the pharmacy’s wholesaler’s wholesaler doesn’t get the drugs directly from the manufacturer, they trust that Continue reading Reliance on Trust in the U.S. Pharma Supply Chain →
