If you are developing a medical device and preparing for clinical trials, you will almost certainly come across the term CRO. It stands for Contract Research Organisation and it is a company that provides clinical research services to sponsors on an outsourced basis. 

In simple terms, a CRO is an external partner that helps you plan, set up and run your clinical study. Depending on your needs, that could mean taking on the entire trial from start to finish or providing specialist support in specific areas where you need extra resource or expertise. 

What Does a CRO Do? 

The scope of what a CRO can do is broad. At the full-service end, a CRO can manage every aspect of your clinical trial including study design, regulatory strategy, site selection and set-up, patient recruitment, data management, monitoring, safety reporting and final submission support. 

For sponsors who have some internal capability but need targeted help, a CRO can also provide support in specific areas. This might be clinical monitoring, biostatistics, regulatory affairs or medical writing, depending on where the gaps are. 

For medical device companies in particular, working with a CRO that understands the specific requirements of device trials is important. Device trials operate under a different regulatory framework to pharmaceutical studies, with distinct requirements around ISO 14155, EU MDR, performance endpoints and post-market obligations. A CRO with genuine medtech experience will understand these nuances and help you avoid costly mistakes. 

Why Do Sponsors Use CROs? 

Access to expertise 

Clinical trials require a wide range of specialist skills that most device companies, particularly early-stage ones, do not have sitting permanently on their team. A CRO brings ready-made expertise across clinical operations, regulatory affairs, data management and medical writing. 

Speed 

Setting up internal clinical trial infrastructure takes time. A CRO already has the systems, processes and networks in place to get your study moving faster. This can make a meaningful difference to your overall development timeline. 

Cost efficiency 

Hiring and maintaining a full in-house clinical team is expensive, particularly for a company running one or two studies. Outsourcing to a CRO means you access the expertise you need for the duration of the study without the long-term overhead. 

Regulatory credibility 

Regulators expect clinical trials to be run to a high standard. Working with an experienced CRO demonstrates that you have the right expertise in place and can support the credibility of your submission. 

Full Service vs Functional Support 

One of the first decisions to make when considering a CRO is how much you want to outsource. Full-service CRO arrangements hand over end-to-end responsibility for the study. Functional service arrangements bring in a CRO for specific tasks or workstreams while the sponsor retains overall management. 

Neither approach is right for every situation. The best model will depend on your internal capabilities, the complexity of your trial and how much control you want to retain over the day-to-day running of the study. 

Big CRO vs Small CRO 

Size is one of the most practical considerations when choosing a CRO and it is worth thinking about carefully. 

Large, global CROs offer significant resource and geographic reach. They can run complex, multi-country trials and have established relationships with sites around the world. For very large studies, this infrastructure can be an advantage. 

However, for most medical device companies, and particularly for small and mid-sized sponsors, a large CRO can come with its own challenges. Your study may not be a priority in a portfolio dominated by large pharmaceutical programmes. You can find yourself passed down to junior staff, faced with less flexibility and paying for overhead that does not directly benefit your trial. 

Smaller, specialist CROs often offer a more attentive and agile service. With a focused team and a narrower area of expertise, they tend to be more responsive, more flexible and better placed to give your study the attention it deserves (Read more about that here: Why Choosing a Small Contract Research Organisation (CRO) Is a Smart Move).

The right choice will depend on the scale and complexity of your study but for many device companies, a specialist smaller CRO will deliver better value and a better working relationship. 

Overall 

A CRO can be one of the most valuable partners a medical device company works with during clinical development. The right CRO brings expertise, capacity and credibility to your trial and helps you navigate the regulatory requirements that sit between your device and market approval.
