Certek Acquires JSS Medical Research

We’re delighted to announce the acquisition of JSS Medical Research, a Canadian-headquartered, full-service Contract Research Organisation (CRO) with global reach across North America, Latin America, Europe and Asia.

JSS Medical Research, founded in 1985 by Dr. John S. Sampalis and headquartered in Laval, Quebec, has established itself as one of the largest Canadian-owned CROs, with a reputation built on scientific rigour, methodological expertise and a deep network of academic affiliations. From its corporate head office in Canada and regional offices in Bogotá (Colombia) and Faridabad (India), JSS supports global pharmaceutical, biotechnology, medical device and nutraceutical clients across the full product lifecycle, from Phase I through to Phase IV and post-approval studies. Over the past decade alone, the business has delivered studies involving more than 500,000 patients across 8,500 sites in over 21 countries and today employs approximately 300 full-time professionals worldwide.

David Harrison, Chief Executive Officer of Certek, said:

“We are delighted to partner with JSS Medical Research and welcome them to Certek. Over nearly four decades, John, Emmanouil, and the JSS team have built a truly differentiated CRO, combining scientific excellence with the agility and customer-centricity that mid-tier sponsors and biotechs increasingly demand. The business is a strong strategic fit for our Life & Materials Sciences Division and significantly extends our international footprint into Canada, Latin America and Asia.

Management recognised the strategic benefits in partnering with a larger group in order to facilitate succession planning and provide increased investment following significant growth and demand for services over the past 12 months. We will support the team to continue investment into people and technologies to meet this demand, whilst preserving the scientific culture, academic affiliations and entrepreneurial drive that have served the company well.”

Dr. Emmanouil Rampakakis, Chief Executive and Scientific Officer of JSS Medical Research, added:

“Joining Certek marks an exciting new chapter for JSS and for our clients. Over nearly four decades, we have built our reputation on scientific rigour, methodological depth and the kind of personal, relationship-driven service that only a focused team can provide, and that will not change. What changes is our capacity; with Certek’s support, we can accelerate investment in the people, technologies and geographic presence needed to serve a market that is growing faster than ever. The momentum in biotech funding is translating directly into a demand for high-quality, agile clinical research partners, and JSS Medical Research is exceptionally well positioned to meet that demand across North America, Latin America, Europe and Asia. I look forward to continuing to deliver on our mission: health research recognised as the standard of excellence, now with the resources to do so at greater scale.”

“Certek’s sophistication and passion for helping its group companies realise their full potential was the single most important factor in our decision to pursue this partnership. In the ever-changing environment of health research, and the contract research industry in particular, partnering with an organisation that is forward-looking, embraces innovation, and provides the means for growth will ensure a healthy and positive trajectory into the coming decades. I am thrilled and honoured that Certek recognised the potential within JSS Medical Research and will join us on what promises to be a remarkable and successful journey. I am also hopeful that adding JSS Medical Research to the Certek Group will be the seed for the group’s growth in the health research sector,” stated Dr. John S. Sampalis, Founder of JSS Medical Research and Professor of Medicine at McGill University and Université de Montréal.

JSS Medical Research will continue to operate under its established brand and from its Laval, Quebec headquarters, with no changes to services or client relationships.
