Clinical Investigation for Medical Devices
A clinical investigation for medical devices is a systematic, controlled study conducted on human subjects to evaluate the safety, performance, and clinical benefit of a medical device. Regulators like EU Notified bodies, US FDA, UK MHRA, Indian CDSCO require this evidence before allowing a device onto the market, particularly for higher-risk device classes. Clinical investigations fall into two broad categories:
Prospective clinical investigations generate new clinical data through a dedicated study designed specifically for your device, patients are enrolled, monitored, and followed up according to a pre-approved protocol.
Retrospective clinical investigations rely on existing clinical data patient records, registry data, or previously collected outcomes analysed against a defined study question, often used to supplement or substitute for prospective data where scientifically justified.
Choosing the right pathway, and knowing when a literature-based clinical evaluation is sufficient versus when an actual investigation is mandatory, is a strategic decision that can save manufacturers months of unnecessary study time or, conversely, prevent a rejected submission built on inadequate evidence.
Clinical Investigation Services for Medical Devices
If you’re a medical device manufacturer in India planning to enter regulated markets like the EU, UK, or US, a well-designed clinical investigation is often the single biggest factor standing between your device and market approval. Poorly structured clinical data is one of the most common reasons for Notified Body queries, FDA deficiency letters, and CDSCO rejections.
i3CGlobal provides end-to-end regulatory documentation and strategic support for prospective and retrospective clinical investigations, covering protocol development, risk classification, regulatory submissions, ethics committee dossiers, and clinical evaluation reports. For the on-ground clinical study execution — site identification, patient recruitment, investigator coordination, and data collection — we work in partnership with REGHELPS SRC, a specialist clinical research organisation, so you get one accountable team covering both the paperwork and the fieldwork.
Whether you’re preparing a Class IIb implant for EU MDR conformity, a Class C device for CDSCO approval, or building a clinical dossier for FDA 510(k) or De Novo submission, our team structures the investigation to meet the exact evidentiary standard your target regulator expects — not more, not less.
As a trusted MDR Regulation Team, I3CGLOBAL guides manufacturer and navigates the complexities of the EU MDR Regulation and gets access to the EU market.
When Is a Clinical Investigation Mandatory?
Not every device needs a dedicated clinical study. Regulatory pathways generally require one when:
- The device is high-risk (implantable, Class III, or novel technology with no established clinical history)
- Existing literature and equivalence data are insufficient to demonstrate safety and performance
- The device uses a new intended purpose, novel materials, or a mechanism of action without adequate precedent
- A Notified Body, CDSCO reviewer, or FDA officer specifically requests it during technical file review
- You’re pursuing equivalence claims that cannot be substantiated through published clinical data alone
We assess this at the very start of engagement through a clinical evaluation gap analysis, so you’re not committing budget to a full-scale investigation unless it’s genuinely required by your target regulatory framework.
Our Clinical Investigation Support Services
Clinical Investigation Plan (CIP) / Protocol Development
We draft the full clinical investigation plan in line with ISO 14155 (for EU/international studies) or CDSCO’s Medical Device Rules, 2017 requirements — study objectives, endpoints, sample size justification, inclusion/exclusion criteria, statistical methodology, and risk-benefit rationale.
Regulatory & Ethics Committee Submissions
Preparation and filing of applications to CDSCO, State Licensing Authorities, and Institutional Ethics Committees (IEC), including Investigator’s Brochure, Informed Consent Form (ICF), and Case Report Form (CRF) templates.
Clinical Evaluation Report (CER) / Clinical Evaluation Plan (CEP)
Structured, MEDDEV 2.7/1 Rev 4 and EU MDR Annex XIV compliant clinical evaluation documentation, incorporating your investigation data alongside literature review and equivalence analysis where applicable.
Retrospective Data Strategy
Where a prospective study isn’t feasible or justified, we build the retrospective evidence package — identifying eligible data sources, structuring the analysis protocol, and preparing the justification rationale regulators expect to see.
Post-Market Clinical Follow-up (PMCF) Planning
Design of PMCF studies and surveys required to maintain conformity post-approval under EU MDR, including PMCF plans and periodic evaluation reports.
Regulatory Strategy & Submission Packaging
Integration of your clinical investigation outcomes into the broader technical documentation — CDSCO Form MD-14, EU MDR Technical File/Design Dossier, or FDA 510(k)/PMA submission.
On-Ground Clinical Study Execution — via REGHELPS SRC
Site feasibility and selection, principal investigator engagement, patient recruitment and monitoring, data collection, and study close-out, delivered through our specialist partner REGHELPS SRC, coordinated end-to-end with our regulatory team so documentation and execution stay aligned throughout the study.
Get a Free Medical Device Clinical Investigation Assessment
Clinical investigation for medical devices are expensive to get wrong a rejected protocol or an inadequately documented study can cost you six months to a year of market delay. Talk to our regulatory team before you finalise your study design, and we’ll tell you honestly whether you need a full investigation, a retrospective pathway, or neither.
Why Manufacturers Choose I3CGlobal + RegHelps SRC
Most manufacturers find themselves splitting clinical work between a CRO that runs the study and a separate consultant who writes the regulatory documentation and the two rarely talk to each other, causing protocol-documentation mismatches that regulators flag immediately.
Our model closes that gap. I3CGlobal owns the regulatory strategy, documentation architecture, and submission from day one; RegHelps SRC executes the clinical fieldwork against the exact protocol we’ve designed for your target market. You get:
- A single point of accountability across strategy, documentation, and execution
- Protocols built for the regulator you’re actually submitting to (CDSCO, Notified Body, MHRA, or FDA) not a generic template
- Documentation that stays audit-ready from day one, not reconstructed after the study ends
- Two decades of I3CGlobal’s regulatory consulting experience across EU MDR/IVDR, US FDA, UK MHRA/UKCA, and ISO 13485 frameworks
- Cost and timeline efficiency from having strategy and execution planned together, not sequentially

Frequently Asked Questions
What's the difference between a clinical evaluation and a clinical investigation?
A clinical evaluation is a documentation exercise assessing existing clinical data (literature, equivalence, post-market data) to demonstrate safety and performance. A clinical investigation is an actual study involving human subjects to generate new clinical data, undertaken when existing evidence is insufficient.
Can retrospective data be used instead of running a new clinical study?
In many cases, yes — provided the existing data is scientifically robust, relevant to your device and intended use, and the retrospective analysis is properly structured and justified. We assess this feasibility during the initial gap analysis.
Is a clinical investigation mandatory for all medical devices in India?
No. Under India’s Medical Device Rules, 2017, clinical investigations are typically required for higher-risk devices (Class C and D) or new/novel devices without established clinical history. Lower-risk devices may qualify through clinical evaluation based on existing literature and equivalence data.
How long does a clinical investigation typically take?
Timelines vary by device risk class, sample size, and regulatory pathway, but most investigations run between 6 and 18 months from protocol approval to final study report, excluding preparatory documentation time.
Who conducts the actual clinical study — I3CGlobal or REGHELPS SRC?
I3CGlobal handles the regulatory strategy, protocol design, and documentation. REGHELPS SRC, our specialist clinical research partner, manages on-ground execution — site selection, investigator coordination, patient recruitment, and data collection.
Do you support clinical investigations for export markets, not just India?
Yes. We regularly support Indian manufacturers preparing clinical investigation documentation for EU MDR, UK MHRA/UKCA, and US FDA submissions, alongside CDSCO approvals for the domestic market.
What documentation is included in your clinical investigation support?
Clinical Investigation Plan, Investigator’s Brochure, Informed Consent Form, Case Report Form templates, ethics committee submission dossiers, clinical study reports, and integration into your Clinical Evaluation Report or technical file.
What happens if our Notified Body or CDSCO rejects our existing clinical evaluation?
We review the rejection or deficiency letter, identify the specific evidentiary gap, and recommend whether it can be resolved through revised clinical evaluation, additional literature analysis, retrospective data, or a new prospective investigation.
Do you help with Ethics Committee (IEC) approval as well?
Yes. We prepare and manage the full Institutional Ethics Committee submission package, including protocol, consent documents, and investigator qualifications, as part of the regulatory approval process.
How much does a clinical investigation cost?
Costs depend on device classification, sample size, number of sites, and study duration. We provide a detailed cost estimate after the initial gap analysis, so you’re not committing budget before knowing what’s actually required.
