Reimbursement in the rare disease landscape is complex. IMAC specializes in the transformation of evidence into a value story that makes payers want to engage.
From the Desk of Louise Perrault
Founder & CEO, International Market Access Consulting (IMAC)
Twenty years ago, after years working in the pharmaceutical industry at the local, international, and global levels, I founded IMAC as a one-person company with a simple goal: to help innovative therapies reach the patients who need them most.
What began in 2006 as an independent consulting practice has grown into a global team of experienced market access professionals working across therapeutic areas, healthcare systems, and international markets.
My vision was never to build a traditional consulting company. I wanted to create a collaborative network of senior experts who work directly with clients, bringing practical experience, strategic thinking, and scientific rigor to complex market access challenges.
Over the past two decades, we have had the privilege of supporting pharmaceutical and biotechnology companies through evolving payer expectations, HTA requirements, reimbursement challenges, and evidence needs across global markets. We are especially proud of our work in rare diseases and high unmet need conditions, where improving access can make a meaningful difference for patients and families.
I am incredibly grateful to the clients, colleagues, and team members who have been part of this journey. Your trust, collaboration, and commitment have shaped IMAC into what it is today.
As we look ahead, our commitment remains unchanged: helping clients navigate complexity and supporting access to meaningful innovation worldwide.
IMAC is a specialized market access consulting firm based on my decades of experience as an executive in the pharma industry and as a senior consultant in a large consulting company.
For well over 15 years, our inspired, dedicated, and specialist team has been the framework of our overall value. Our goal is to continue to demonstrate our relentless commitment—exemplifying our integrity, innovative solutions, and exceptional personalized support.
Since 2006, in this ever-evolving environment, we have collaborated with our clients bringing highly specialized technologies to targeted patient populations. IMAC has gained a vast knowledge of how to gain market access for your therapies and improve patient outcomes.
Louise Perrault
President and CEO
IMAC consists of highly experienced, senior consultants with decades of successful projects. Along with our extended network of experts, our team is uniquely positioned to provide innovative and strategic methods to ensure the success of your project.
The global reimbursement landscape is rapidly evolving, with more highly specialized therapies and treatments for rare diseases emerging every day. Our team has an unparalleled track record of success in navigating these complexities and securing access for innovative therapies.
Amid rising healthcare costs, strategic economic modeling is essential for successful reimbursement in today’s markets. Our highly experienced HEOR team brings decades of expertise in developing innovative economic models to support effective market access and reimbursement strategies.
Market access for rare diseases presents unique challenges: limited data, a knowledge gap among payers, higher pricing, and a lack of tailored evaluation frameworks. Partnering with our team, with deep expertise in rare disease market access strategies, helps overcome these barriers and ensures effective access for innovative treatments.
Real-world evidence (RWE) is increasingly crucial for informed decision-making by regulators, payers, and providers, shaping the evolving landscape of market access. Discover how our expertise in RWE generation can support your access strategy.
