Clinical Evidence

Achieving CE marking under the EU Medical Device Regulation (MDR 2017/745) requires more than technical compliance. It requires credible clinical evidence that proves your device is safe, performs as intended, and delivers real clinical benefit.This page explains, in practical terms, how Prospective Clinical Studies and Randomized Controlled Trials (RCTs) support MDR approval so you can choose the right strategy to accelerate market access.

Why Clinical Studies Matter Under MDR

Under MDR, manufacturers must demonstrate:

  • Clinical safety
  • Clinical performance
  • Clinical benefit

This is achieved through a Clinical Evaluation (Article 61, Annex XIV), often supported by clinical investigations (Annex XV). For many Class IIa, IIb, and III devices, clinical studies are no longer optional they are a regulatory and commercial necessity. Strong clinical evidence doesn’t just satisfy regulators, it builds trust with clinicians, payers, and patients.

Strong clinical evidence doesn’t just satisfy regulators—it builds trust with clinicians, payers, and patients.

Prospective Clinical Studies

A prospective clinical study is a planned investigation where patients are followed forward in time after receiving the device. Outcomes are predefined and collected according to a Clinical Investigation Plan (CIP). These studies may be:

  • Single-arm (device only)
  • Comparative (against standard of care or literature benchmarks)
When Prospective Studies Work Best

Prospective studies are widely accepted under MDR when:

  • The device is Class IIa or IIb
  • The technology is incremental or well-established
  • Clinical benefit is already known
  • Randomization is impractical or unethical
Key Benefits
  • Faster study start-up
  • Lower cost and complexity
  • Strong real-world relevance
  • Often sufficient for CE marking when well justified
Limitations
  • Higher potential for bias
  • Weaker evidence for novel or high-risk devices
  • May not support superiority claims

Randomized Controlled Trials (RCTs)

A Randomized Controlled Trial is a prospective study in which subjects are randomly assigned to (1) The investigational device, or (2) A control group (standard of care, alternative device, or sham). RCTs are considered the gold standard for clinical evidence.

When MDR Typically Expects an RCT

Notified Bodies often expect RCTs for:

  • Class III devices
  • Implantable devices
  • Novel or breakthrough technologies
  • Claims of superior clinical performance
Key Benefits
  • Highest level of scientific credibility
  • Minimizes bias
  • Strong support for benefit–risk assessment
  • Highly persuasive for regulators and investors
Limitations
  • Higher cost and longer timelines
  • Operational and ethical challenges
  • Not always feasible for every device

Prospective Study vs RCT — At a Glance

Feature Prospective Study Randomised Controlled Trial
Study design Observational or comparative Comparative
Randomisation No Yes
Evidence strength Moderate High
Typical MDR use Class IIa / IIb Class IIb / III
Cost & complexity Lower Higher
Suitable for novel devices Sometimes Preferred

Choosing the Right Clinical Strategy

A Prospective Study May Be Sufficient If:

  • Your device is an iteration of existing technology
  • You can justify a state-of-the-art comparison
  • The risk profile is moderate
  • You aim for efficient market entry

An RCT Is Advisable If:

  • Your device is innovative or implantable
  • Clinical benefit is not yet established
  • You claim superiority over existing solutions
  • Long-term market acceptance is critical

Choosing the wrong study design is one of the most common causes of MDR delays.

Beyond CE Marking: The Market Value of Strong Clinical Evidence

Well-designed clinical studies can help you:

  • Accelerate Notified Body approval
  • Strengthen clinical adoption
  • Support pricing and reimbursement
  • Increase investor confidence
  • Reduce post-market compliance risk

Clinical evidence is not just regulatory documentation—it is a commercial asset.

service related FAQ’s

Can RegHelps handle PMCF for devices already on the market?2025-08-08T11:02:42+05:30

Absolutely. We can take over PMCF activities for devices already CE-marked and on the EU market, ensuring that your data collection, evaluation, and reporting fully meet MDR requirements — even if your existing documentation needs corrective action before the next Notified Body audit.

Product liability insurance under your service explain2025-08-05T11:06:35+05:30

As part of our commitment to regulatory compliance and risk management, we recommend that all non EU manufacturers have valid Product Liability Insurance when appointing us as their European Authorized Representative (EC REP). While it is not a legal requirement under MDR/IVDR for the EC REP to request proof of insurance, many Competent Authorities and Notified Bodies may inquire about the manufacturer’s liability coverage during inspections or audits. Having proper insurance also demonstrates due diligence and protects your business in the event of product-related claims in the European market. We do not provide insurance ourselves, but we can guide you on what to include based on your device risk class and market exposure.

Will your EC REP name appear on my product label?2025-08-05T10:22:35+05:30

Yes. According to MDR and IVDR requirements, the EC REP’s name and address must be clearly visible on the product labeling, outer packaging, or accompanying documents, allowing EU authorities to easily identify the representative.

Do your firm provide UDI (Unique Device Identification) Support?2025-08-05T12:14:05+05:30

Yes, we provide full support for UDI implementation and registration in compliance with EU MDR 2017/745 and IVDR 2017/746 requirements. Our team assists manufacturers in assigning and structuring UDI-DI and UDI-PI codes based on the device classification and intended use. We also help in ensuring proper placement of UDI on labeling, packaging, and Instructions for Use (IFU), as well as preparing for UDI module submission once it becomes fully functional within EUDAMED.

Our services cover:

  • UDI-DI and UDI-PI structure guidance

  • Compliance with GS1, HIBCC, or ICCBBA issuing agencies

  • UDI label and packaging review

  • Preparation for EUDAMED UDI/Device registration module

  • UDI-related documentation for your Technical File and CE submission

By integrating UDI properly, we help ensure device traceability, reduce market delays, and support full regulatory compliance across the EU.

Transfer of US Agent Possible? Explain the process2025-07-31T14:12:58+05:30
