HOST Emily Friedland | VP of Clinical Research, DCN Dx ABOUT DCN DX EXPERT INSIGHTS DCN Dx Expert Insights examines the technical, regulatory, clinical, and manufacturing decisions that shape the development and commercialization of in vitro diagnostics.

A site management CEO and a human factors specialist on what sponsors miss before a diagnostic study ever starts. Most conversations about IVD clinical research happen from the sponsor’s side of the table. This episode flips that. Emily Friedland, VP of Clinical Research at DCN Dx, sits down with Missy Farrell, founder and CEO of , and Karen Seidler, Ph.D, CEO and Principal at , to talk about the two stages that happen before a protocol is finalized: the human factors work that determines whether real users can operate a device safely, and the site feasibility work that determines whether a clinic can deliver the study a sponsor designed on paper. For sponsors and CROs, the payoff is practical. Missy explains why prevalence numbers on a feasibility questionnaire routinely mislead sponsors about who a site can enroll, and Karen walks through why combining a human factors validation study with a clinical study creates logistical problems that are hard to see coming. Together they make the case for treating these two disciplines as sequential, not overlapping, and for asking sites and device teams sharper questions much earlier in development.

Your lateral flow assay performs at the bench. Will that performance hold on the manufacturing line? Manufacturing introduces conditions the assay may not have faced at the bench. Reagent delivery must remain consistent throughout longer runs, while materials move under tension on production equipment. Changes in dispensing and drying can expose signal variation, nonspecific binding, material failures, or yield loss. For immunoassay developers, finding those problems after the assay design is locked can send the program back into development. The better time to address them is during development, while the chemistry, materials, and process can still be evaluated together. In this episode of Expert Insights, DCN Dx Chief Operating Officer Pat Vaughan, Ph.D., who leads assay development, engineering, and manufacturing operations, joins host Trevor Brown, M.Sc., Chief Revenue Officer, to explain what changes between the bench and the manufacturing line. They discuss what immunoassay developers should evaluate before the design is locked and how assay scientists and manufacturing engineers can work together from the start.

Many IVD clinical studies still run on a patchwork of disconnected tools: a file share here, a spreadsheet there, a separate system for clinical operations and another for the data. The handoffs between them put time, money, and clean data at risk. Since 2021, DCN Dx has been developing something different: one connected platform on Veeva, with the electronic trial master file, EDC, and CTMS all talking to each other. In this candid discussion, host Emily Friedland (VP of Clinical Research, DCN Dx) sits down with two of the people who built and run it, Thomas Martinache (Associate Director, Data Management, DCN Dx) and Jill Hutton-Pugh (Clinical Trial Manager, DCN Dx), along with John Acampado (Senior Director of Clinical Strategy, Veeva). They get into what the old patchwork model cost, how DCN put the connected platform together piece by piece, and, most of all, what it changes for the sponsors who hire them: faster study startup, real-time visibility into enrollment and milestones, cleaner data with fewer manual handoffs, and a compliant foundation that an emerging IVD or MedTech company can grow on. The conversation leads into the team’s Veeva webinar on July 15, Platform Over Patchwork: How Consolidation Drives CRO Efficiency, where DCN Dx will share its journey of moving onto a single platform to drive operational efficiency in high-intensity trials, including 60% improvement in IMV preparation, 45% reduction in build time, and 30% faster study closeout. ⁠Register for that webinar here⁠: https://veeva.zoom.us/webinar/register/WN_m8krwBa4RLCnK17MpVZVCw#/registration Emily Friedland | VP of Clinical Research, DCN Dx Emily Friedland is Vice President of Clinical Research at DCN Dx, where she leads the company's clinical operations across IVD and medical device studies.

The 2026 IVDR transition deadlines are here, and a lot of IVD companies are sitting still. After the European Commission proposed a revision to the regulation in December 2025, many manufacturers are waiting to see what survives before they file. By late May, notified bodies reported that submissions had slowed so much that some have cut staff and a few may close. The old IVDD deadlines keep running out, the dates for higher-risk classes have already passed, and the Commission's message has been consistent: no more extensions. Dan Simpson, Director of Regulatory Affairs at DCN Dx, and Sarah Barchard, Senior Clinical Trials Manager at DCN Dx, talk through what the waiting costs a company that has to sell in both the EU and the US, and why it pays to plan for both markets at the same time instead of one after the other. Dan takes the regulatory side: where the two systems differ, and how those differences shape design and development long before anyone files. Sarah takes the clinical side: where EU and US requirements pull in different directions during analytical and clinical work, and what it takes to run studies that hold up in both places. This conversation leads into their RAPS sponsored webcast, The IVDR Transition in 2026: Parallel Regulatory Planning for EU and US Market Entry, on June 17 at 12pm ET.

In this episode, Emily Friedland, VP of Clinical Research at DCN Dx, talks with two guests who come at QMSR from different directions: the regulatory strategy side and the quality systems implementation side. Dan Simpson, RAC, Director of Regulatory Affairs at DCN Dx, covers the regulatory framing: what changed with the QMSR transition, how to map an ISO 13485-based QMS against QMSR’s U.S.-specific requirements, and what FDA’s updated inspection approach under CP 7382.850 means for how teams document and maintain QMS records. Kevin Gunning, Principal Consultant at Gunning Quality Systems LLC, brings the quality systems implementation perspective: what it takes to build and maintain a QMS that holds up under QMSR, how organizations should think about the practical work of a gap assessment and remediation, and what teams with established ISO 13485 systems often overlook when they assume the transition is “mostly handled.” Kevin has spent more than 25 years implementing and managing quality systems at IVD and medical device companies, and has extensive firsthand experience on both sides of FDA and ISO audits and inspections. Together, Dan and Kevin cover the four gap areas that matter most for IVD manufacturers, what FDA can now request during an inspection that was previously off-limits, and how to scope a proportional remediation effort.

Specimen strategy is one of the most common sources of avoidable delay in IVD development. Teams that defer specimen decisions until after the evidence plan is set tend to discover the mismatch at the worst possible time: during analytical validation, clinical performance work, or submission prep. In this episode of Expert Insights, Mitzi Rettinger talks with Jim Boushell, Senior Vice President of Biospecimens at DCN Dx, about what experienced teams define early so their specimen sets and data packages hold up under regulatory scrutiny. Jim has spent decades building biorepositories and supporting diagnostic developers. The conversation covers how to align a specimen plan to an evidence plan from the start, where programs get burned on matrix selection, prevalence, comparator methods, metadata, and pre-analytical handling, and what a high-integrity, audit-ready data package should contain. Topics in this episode: -What "specimen strategy" includes and why it is separate from procurement -Early warning signs that a program is headed for specimen-related delays -The most common failure modes in specimen planning -The minimum inputs a developer needs to define before designing a collection -When banked specimens make sense versus prospective collection -How DCN Dx runs prospective collections: specimen types, special handling, site operations, and data packages -What "audit-ready" documentation means for IVD submissions -Where handoffs fail when collections, assay development, and clinical execution are split across multiple groups Learn more about DCN Dx's prospective biospecimen collections at dcndx.com/biospecimen-service ABOUT DCN DX EXPERT INSIGHTS DCN Dx Expert Insights examines the technical, regulatory, clinical, and manufacturing decisions that shape the development and commercialization of in vitro diagnostics.

As rapid diagnostic programs transition from R&D to scaled production, small sources of variation can quickly become major risks. In this episode of Expert Insights, Mitzi Rettinger, Chief Revenue Officer at DCN Dx, sits down with Daniel Levenson, Business Development Manager at KinBio, to discuss what truly changes when you move from manual processes to automated, repeatable manufacturing systems. The conversation goes beyond dispensing and strip cutting to address the often-overlooked bottlenecks in vial filling, kit assembly, packaging, and sealing. Daniel explains how throughput challenges, moisture control, seal integrity, and alignment issues can affect lot consistency, and why automation must extend across the full production workflow, not just the strip. They also explore the role of in-line vision systems and defined critical-to-quality attributes (CTQs) in reducing manufacturing risk. As multiplex tests and more complex point-of-care formats become more common, developers must design flexibility, inspection, and traceability into their processes early. The result: fewer surprises, stronger process control, and a clearer path to scalable production. Guest Daniel Levenson is Business Development Manager at Shanghai Kinbio Tech Co., Ltd. He brings years of hands-on technical experience in rapid test manufacturing to his work supporting developers scaling into automated production.

A DCN Dx Expert Insights conversation with Charlie Mamrak, CEO at DCN Dx, hosted by Mitzi Rettinger. Most IVD programs don’t lose months because a single experiment failed. They lose months at the seams: development to clinical, clinical to regulatory, scale-up to routine manufacturing, and specimen strategy to evidence generation. In this episode, DCN Dx CEO Charlie Mamrak explains the business decisions behind DCN’s integrated services model, why biospecimens became a priority for IVD developers, and how he evaluates what to build, buy, or collaborate on next. This is a strategy conversation, designed for teams who care about execution, risk, and real-world constraints of diagnostics services companies. What you’ll hear in this episode: -Why integration is the point: what changes when rapid testing CDMO capabilities and IVD clinical research (CRO) services operate as one platform. -Why biospecimens: what DCN has heard from customers, what offering prospective biospecimens collections changes for IVD developers, and how it fits the broader integration plan for DCN Dx. -Workforce development as strategy: why DCN teaches the Basic Lateral Flow Course. -Build vs. buy vs. collaborate: a CEO framework for deciding when new capabilities reduce friction for customers and align to corporate core values vs. simply expanding the menu of services. Guest: Charlie Mamrak is CEO of DCN Dx. He joined DCN Dx in 2020 after leading multiple diagnostics and life science tools companies, including SeraCare Life Sciences.

A DCN Dx Expert Insights conversation with Dan Simpson, RAC, Director of Regulatory Affairs at DCN Dx, and Emily Friedland, VP of Clinical Research at DCN Dx. FDA’s Predetermined Change Control Plan (PCCP) mechanism is designed to let manufacturers pre-specify certain post-clearance or post-approval changes, along with the protocol and acceptance criteria used to verify and validate those changes. For AI-enabled device software functions, PCCPs are now a core concept in FDA’s approach to iterative software updates. In this episode, we break down what belongs in a PCCP, how it shows up in a marketing submission, and how teams can connect PCCP planning to design controls, risk management, and quality system processes so the plan is executable after authorization, not just well written on paper. What we cover (bullets) • What FDA means by a PCCP and when it is relevant for AI-enabled IVDs • The three core components FDA expects to see (and why each one matters) • How PCCPs interact with marketing submissions (510(k), De Novo, PMA) and public-facing submission summaries • Where teams get tripped up: scope control, evidence expectations, and operationalizing the plan inside the QMS • What the broader “PCCPs for Medical Devices” draft guidance signals for non-AI device changes (hardware, materials, software) Dan Simpson, RAC is Director of Regulatory Affairs at DCN Dx, supporting regulatory strategy, pre-submission engagement, and U.S. and global submission planning for diagnostics teams. Emily Friedland is the VP of Clinical Research at DCN Dx, where she leads and fosters growth within the clinical operations teams. Questions about whether a PCCP makes sense for your device, or how to structure one so it holds up through review and post-market execution? DCN Dx’s Regulatory Affairs Services help IVD teams develop successful regulatory plans and submissions. We support FDA pathways including 510(k), De Novo, and PMA, with early Pre-Sub positioning and submission development, and we can advise on accelerated programs like Breakthrough Devices and STeP when they fit the product.
