Medical affairs is being redefined. Historically positioned as a steward of scientific exchange and compliance, medical affairs has often been perceived as a support function. Today, its remit is broader and more complex, spanning evidence generation, external engagement, internal decision support, and the integration of patient and clinical insight across the pharmaceutical enterprise, while still operating within strict ethical and regulatory boundaries.
Paul Mastoridis has been at the forefront of this shift, shaping a model of medical affairs that is scalable, data-driven, and deeply integrated with digital innovation. Across more than 25 years in global leadership roles, Mastoridis has helped organizations rethink not only what medical affairs does, but what it can enable. “Medical affairs exists to bring scientific truth and patient reality into the same conversation, so decisions are grounded not only in data, but in clinical meaning,” says Paul Mastoridis, a past board member of PKG Health at the time of its acquisition by Empatica, reflecting his broader engagement with clinically validated digital technologies in neurology.
When medical affairs is designed with the same rigor as drug development itself, it becomes a force that accelerates decision-making, strengthens products, and improves patient experience. With a career spanning drug development, respiratory devices, building medical affairs teams, artificial intelligence, and automated digital solutions, his work reflects a consistent focus on applying rigor, governance, and scalability to complex medical and technological environments.
Medical Affairs as a Strategic Driver of Value
For Mastoridis, the modern medical affairs function plays an active role in shaping therapeutic strategy, generating evidence, and informing how products are developed and experienced. “Medical affairs has to function as a strategic engine,” Mastoridis says. “That means aligning early with research, development, and commercial teams around shared objectives.” This alignment not only allows medical insights to flow across the organization, reducing fragmentation, but also ensures that patient perspectives and real-world evidence inform decisions at every stage to ensure the best results.
This vision has guided Mastoridis’ work across multiple therapeutic areas, particularly in respiratory care. His involvement in developing digital adherence systems and connected devices for asthma and COPD illustrates how medical affairs can influence both product design and patient outcomes when it is embedded upstream rather than positioned downstream.
Designing Scalable Frameworks for Global Impact
Scalability is a recurring theme in Mastoridis’ leadership approach and he emphasizes modular design, creating global frameworks that establish consistency while allowing for local adaptation. “Scalability is non-negotiable. When frameworks are built correctly, they improve speed, reduce redundancy, and preserve scientific rigor,” he says. This approach proved critical during his time at Novartis, where medical devices and digital programs were expanded across regions with differing regulatory and clinical landscapes. Rather than forcing uniformity, Mastoridis focused on adaptable operating models that empowered regional teams while maintaining a cohesive global strategy.
Equally important is the way teams are built to operate within these frameworks. Mastoridis has repeatedly built medical affairs organizations from the ground up, establishing clear roles, governance, and performance metrics. The result is high-impact teams that can grow without losing focus or effectiveness, even in complex multinational environments.
Turning Data and Digital Enablement Into Advantage
Data is central to Mastoridis’ outlook on the evolution of medical affairs, viewing it not as a reporting tool, but as a source of foresight that enables proactive rather than reactive decision-making. His background in machine learning and artificial intelligence, including a patent in diagnostics for chronic respiratory disease, shapes this perspective. By analyzing patient behavior and treatment outcomes with greater precision, organizations can anticipate challenges, tailor engagement, and deliver medical value more effectively.
Automation plays a complementary role. Digital platforms that streamline content delivery, automate standard inquiries, and surface real-time insights allow medical professionals to focus on higher-value scientific engagement. “Digital tools don’t replace teams,” says Mastoridis. “They elevate them.” The cultural component is critical, requiring leaders to foster digital fluency and continuous learning so technology enhances, rather than overwhelms, human expertise.
Advancing Patient-Centered Impact Through Innovation
The strategic transformation Mastoridis advocates is ultimately driven by impact. His work consistently returns to the patient, from FDA approval through post-marketing studies and real-world evidence generation. “We have a responsibility to lead this change not just to improve business performance, but to better serve patients,” he says. In respiratory care, this has translated into digital adherence solutions that improve outcomes while generating meaningful data. More broadly, it reflects a belief that medical affairs can shape healthcare systems, not merely support them.
As pharmaceutical organizations face increasing complexity, Mastoridis’ model offers a blueprint for how medical affairs can evolve with intention and impact. It is a shift that demands leadership, discipline, and a willingness to rethink legacy structures, but one that delivers measurable value for both patients and the industry.
