It’s not a Farewell, it’s a Welcome! …

Dear friends,
It’s hard to believe that almost five years have passed since we launched the Nitrosamine Exchange. When we started this journey, none of us could have imagined how much the nitrosamine landscape would evolve. Every few months seemed to bring new scientific questions, new regulatory expectations, new analytical challenges, and new uncertainties. As the science continued to evolve, something else was evolving alongside it—our community. Looking back, I’m incredibly proud of what we’ve built together, because Nitrosamine Exchange became much more than a place to exchange information. It became a place where people connected, challenged each other’s thinking, shared ideas openly, and helped solve problems that no single company, organization, or regulator could solve alone.
For me, Nitrosamine Exchange has always been a window into everything happening in our field. Not because we always had the answers, but because we had people who were willing to ask thoughtful questions, share their experiences, and help others navigate unfamiliar territory. It has been remarkable to watch scientists from around the world come together, often from organizations that would normally only interact at conferences or through publications, and engage in meaningful discussions with a common goal of advancing science.
One of the greatest privileges has been watching so many of you grow alongside this community. Many of the members who joined during those early days have become trusted voices that many of us now rely on for perspective and guidance, Yosuke-san comes to mind! Even today, you continue to shape discussions, challenge assumptions, and generously share your expertise with colleagues you’ve never met. When I think about what we’ve accomplished over the years, I don’t think about the number of members we’ve welcomed, I think about the countless moments when someone posted a difficult question and, within hours, experts from across the world stepped in to help. I think about the healthy scientific debates that pushed all of us to think differently. I think about experienced professionals taking time to explain complex concepts to someone just entering the field. Those moments are what define a vibrant community.
The Nitrosamine Exchange wasn’t built overnight. It was built one registration, one discussion, one webinar, one challenging question, one thoughtful answer, and one generous contribution at a time. More importantly, it was built on trust. We created a network of colleagues—and I would even say friends—who know that whenever a new challenge emerges, there is a community willing to help. That spirit of collaboration has always been, and will continue to be, the greatest strength of what we’ve created together.
Today, I’d like to share something that I’ve been working on for quite some time. Over the past year, I’ve had the privilege of working closely with USP to take everything we’ve learned from building the Nitrosamine Exchange—what worked well, what we learned along the way, and where we saw opportunities to do even better—and use those lessons to create something much larger. The result is USP Exchange, an enterprise-level scientific community designed to bring together experts across many of today’s most important pharmaceutical topics.
The vision is actually quite simple. We asked ourselves a fundamental question: What if we could take the same collaborative model that has made Nitrosamine Exchange so valuable and extend it to other scientific communities facing similar challenges? Nitrosamines will continue to be an important part of this new community, but they will now be joined by discussions around Extractables & Leachables, Microbiology, Digital Standardization, Packaging, Emerging Drug Delivery Systems, Novel Excipients, Compounding, Green Chemistry, and many other scientific areas as the community continues to grow. The topics will expand, but our purpose remains exactly the same—to create a place where experts learn from one another, share practical experience, and collectively move science forward.
I’ve always believed that knowledge becomes more valuable when it is shared. I remember hearing someone once describe nitrosamines exchange as places where people come to “get free stuff.” While I understand where that perspective comes from, it has never reflected what I’ve experienced. People don’t stay engaged in communities for years simply because they receive information. They stay because they become part of meaningful conversations. They stay because they discover people willing to challenge their thinking, offer different perspectives, and help solve problems together.
One of my favorite quotes comes from Helen Keller: “Alone we can do so little; together we can do so much.” Over the last several years, I’ve been fortunate to witness that philosophy every day within this community. I’ve also had the privilege of experiencing it firsthand while serving on the ICH M7 Revision Working Group. Sitting alongside experts from industry and regulatory agencies from around the world, discussing difficult scientific questions, respectfully disagreeing, listening carefully, building consensus, and ultimately advancing science together has been one of the most rewarding experiences of my career. It reinforced something that Nitrosamine Exchange has been teaching us since its very beginning: when we develop a common understanding together, adopting new paradigms and best practices becomes far easier than simply asking others to change.
Over the coming weeks, we’ll be sharing more information about our transition to USP Exchange. Personally, I like to think of it as moving into a larger home rather than leaving one behind. Nitrosamines will always remain an important room in that house, but we’ll now have the opportunity to interact with colleagues working in many related scientific disciplines. Those new conversations will enrich our own work while creating opportunities for collaboration that simply weren’t possible before.
In many ways, every one of you should consider yourselves founding members of USP Exchange. The culture we build in this new community will be built on the foundation that you helped create over the last five years. Your willingness to participate, share your expertise, ask difficult questions, and support fellow scientists is the reason we’re able to take this next step with confidence.
I’m genuinely excited about what’s ahead, and I sincerely hope you’ll continue this journey with us. As always, I’d love to hear your thoughts. Whether you have ideas, recommendations, compliments, concerns, or simply want to share your perspective, please don’t hesitate to reach out to me directly at ner@usp.org. This community has always been shaped by its members, and I hope that never changes.
Finally, thank you. Thank you for believing in this community from the very beginning. Thank you for sharing your knowledge so generously and for helping complete strangers become colleagues and collaborators. Most of all, thank you for proving that when people come together with a shared purpose, remarkable things can happen. I look forward to welcoming you to our new home and to building the next chapter together.
Warm regards,
Naiffer Romero
