European Clinical Trial Software

Electronic data capture, trial management and trial master file systems hold pseudonymised patient data, protocol details and audit trails that regulators inspect for years. These European alternatives to Veeva Vault Clinical are run by companies in Germany, Sweden, the Netherlands, Norway, France and Switzerland, with several naming a European data centre.

How we rank these tools — 4-step process
  1. 1
    European ownership, verified

    The company is headquartered and incorporated in the EU, EEA, the UK, Switzerland or Israel, and processes customer data in Europe or Israel. A US parent company disqualifies a tool from this page regardless of where its servers are.

  2. 2
    Category fit and hands-on review

    What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.

  3. 3
    Compliance and pricing check

    GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.

  4. 4
    Position on this page

    Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Vendors can pay for more visibility, higher up on the review pages; it never affects whether a tool is listed. Editorial policy

Key takeaways

  • Ledidi of Oslo is the only vendor in this list that shows euro prices openly: EUR 10, EUR 25 and EUR 45 per seat per month on annual billing for its base plans.
  • Ennov Clinical of Paris combines CTMS, eTMF, EDC and RTSM and is also offered as an on-premises installation, which suits sponsors that keep systems on their own servers.
  • Climedo of Munich bills per active study with unlimited users and sites, and states Frankfurt servers on an AWS region.
  • Viedoc of Uppsala states ISO 27001:2022 and a SOC 2 Type 2 report on request, while its privacy policy mentions possible transfers to the USA.
  • BSI Life Sciences of Baden has no EDC at all, so it complements a data capture system such as secuTrial and does not replace one.

European clinical trial software is the set of electronic data capture, patient-reported outcome, consent, trial management and trial master file systems that sponsors, hospitals and research organisations use to run studies, supplied by companies in Germany, Sweden, the Netherlands, Norway, France and Switzerland, so that a European entity signs the contract and the data protection terms.

Every European clinical trial software tool reviewed

#1 Climedo

Munich, Germany Monthly SaaS fee plus one-time set-up fee per active study; no figures published Demo on request

Best for: Device and pharma teams that prefer per-study pricing with unlimited users

  • Operating company. Climedo Health GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Frankfurt (AWS region); US hosting on request
  • Source code. Closed source
  • Replaces. Veeva Vault Clinical, Medidata Rave, OpenClinica

Climedo is a Munich vendor of EDC, eCOA, eConsent and televisits whose billing is built around the study, not the seat. The site describes a monthly fee and a one-time set-up fee per active study, with unlimited users and sites in each package, and support sold separately in bronze, silver and gold tiers. Patients can answer through an SMS or email link or a QR code without installing an app.

Climedo Health GmbH is registered in Munich as HRB 233195, and the pages state Frankfurt servers on an AWS region, with US hosting only on request. According to the vendor, the system is auditable against ICH GCP, GAMP5 and FDA 21 CFR Part 11, and study data sits with an ISO 27001-certified hosting partner. The founding year and owner are not stated, and no CTMS or eTMF is listed.

What Climedo does well

  • Users and sites are unlimited in every package
  • Servers in Frankfurt, stated on its own pages
  • GmbH with a register entry in Munich
  • eCOA, eConsent and televisits in one product
  • Link or QR code entry, no app needed

Where Climedo falls short

  • Fee structure shown, no amounts
  • Frankfurt hosting runs on AWS
  • Nothing for CTMS or eTMF
  • Founding year and owner missing from the pages checked

Standout feature. Climedo prices by active study with unlimited users and sites, so adding investigators does not raise the fee.

#2 Marvin EDC

Munich, Germany Not published; contact the vendor for a quote Demo on request

Best for: Teams that want CDISC structure and randomization together in a system hosted in Germany

  • Operating company. AB Cube Germany GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Germany (Noris Network and Hetzner data centres)
  • Source code. Closed source
  • Replaces. Veeva Vault EDC, Medidata Rave

Marvin EDC is a CDISC-native EDC that the vendor positions as a certified platform, with RTSM for randomization and material handling, ePRO, a separate safety module and eConsent as an add-on. Its AI-assisted eCRF creation drafts a form from the protocol, adds edit checks and generates synthetic patients for testing before real data enters.

The operator is AB Cube Germany GmbH in Munich, and the old xclinical.com domain now redirects to marvin.now. The FAQ names Noris Network and Hetzner as the two German hosting providers, and the site reports their data centres as ISO 27001, TUVIT and ISAE 3402 certified. The GCP and 21 CFR Part 11 line is a claim, so ask for the validation package. The parent group behind AB Cube is not described.

What Marvin EDC does well

  • Hosting providers in Germany named by the vendor
  • Built around CDISC from the start
  • RTSM and ePRO from the same family
  • Test patients generated for form checks
  • APIs and a Data Hub for integration

Where Marvin EDC falls short

  • No price on the site
  • Owning group not named
  • CTMS and eTMF absent from the product list
  • Part 11 wording is a claim, not a certificate

Standout feature. Marvin EDC creates synthetic patients to test an eCRF before go-live.

#3 Ledidi

Oslo, Norway Base plans EUR 10 (Personal), EUR 25 (Professional/Team), EUR 45 (Organisation) per seat per month billed annually; trial features quoted per project plus a one-time startup cost Demo on request

Best for: Academic groups and small CROs that want visible prices and a free test build

  • Operating company. Ledidi AS
  • Jurisdiction. EEA, not EU (Norway)
  • Where the data sits. AWS eu-central-1 (Frankfurt), backups in eu-north-1 (Stockholm)
  • Source code. Closed source
  • Replaces. Veeva Vault EDC, Medidata Rave, REDCap-style builds

Ledidi is an Oslo platform for clinical trials and registries that shows its base plans in euro on a public page: EUR 10 per seat per month for Personal, EUR 25 for Professional or Team, and EUR 45 for Organisation, billed annually. Trial functions are priced per project through a calculator plus a one-time startup cost, so the first number is not the final one.

Ledidi AS carries enterprise number 917 137 137. Norway is in the EEA, so the contracting entity is European even outside the EU. Data is stored in the AWS Frankfurt region with backups in Stockholm, and the site mentions confidential computing and end-to-end encryption. Design Mode costs nothing until go-live, a 30-day trial exists, and the AI Study Builder drafts a structure from an uploaded protocol. Ownership is not stated.

What Ledidi does well

  • Seat prices in euro on a public page
  • No charge for Design Mode until go-live
  • Frankfurt primary, Stockholm backups
  • One platform for trials and registries
  • Trial period of 30 days

Where Ledidi falls short

  • Trial cost depends on a calculator or quote
  • Runs on AWS
  • Owner not named
  • Nothing for CTMS or eTMF

Standout feature. Ledidi lets a team build and test a study in Design Mode at no charge until the project goes live.

#4 Castor

Amsterdam, Netherlands Founded 2012 Pricing on request; itemised fixed-scope proposal Demo on request

Best for: Teams that want to take only some modules and decide how much of the build the vendor does

  • Operating company. Ciwit B.V. (Castor)
  • Jurisdiction. EU (Netherlands)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. Veeva Vault EDC, Medidata Rave

Castor splits its platform into EDC, eCOA, CDMS and eConsent so a buyer can take only the pieces needed, and adds a Catalyst feature that extracts source data with AI while a person reviews each result. The EDC page offers three routes to a live study (self-service, assisted, or built by Castor), with deployment quoted at 3 to 12 weeks, plus data management and eCOA translation services.

The privacy policy names Ciwit B.V., known as Castor, at Fred. Roeskestraat 115 in Amsterdam, acting as processor for patient data in CDMS and eConsent and as controller for website and account data. The About page dates the start to 2012, as a project of Dr. Derk Arts. Buying runs through a form, a call, a protocol review and a demo, ending in an itemised proposal within 5 business days. The pages show no hosting region.

What Castor does well

  • Modules can be taken separately
  • Self-service, assisted or vendor-led build
  • Open API for other systems
  • Amsterdam entity named in the privacy policy
  • Fixed-scope, itemised proposals

Where Castor falls short

  • Data centre region absent from the pages checked
  • Prices are not published

  • Vendor services raise the total

Standout feature. Castor offers self-service, assisted and Castor-led builds of the same study under one platform.

#5 Viedoc

Uppsala, Sweden Pricing on request; single study licence or multiple licence model Demo on request

Best for: CROs and sponsors running several studies in parallel under one licence model

  • Operating company. Viedoc Technologies
  • Jurisdiction. EU (Sweden)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. Veeva Vault Clinical, Medidata Rave

Viedoc is a Swedish suite on one clinical database, covering EDC with drag-and-drop CRF design, ePRO, randomization, trial supply management, medical coding, televisits, record sharing, eSignature, reports, an API and an eTMF. The pricing page names a Single Study Model and a Multiple License Model, and the fee includes maintenance, hosting and technical support, with no setup fees when you build the study yourself.

The security page lists Uppsala as headquarters, with subsidiaries in Tokyo, Shanghai and Raleigh, and the home page says the system supports 7,500 clinical trials. It states ISO 27001:2022 across all Annex A controls and a SOC 2 Type 2 report on request. The privacy policy mentions transfers to the USA, and the hosting country and the legal form of the contracting company were not on the pages checked.

What Viedoc does well

  • ISO 27001:2022 named on the security page
  • SOC 2 Type 2 report available on request
  • Wide module list, eTMF included
  • Licence model for multiple concurrent studies
  • Hosting and support covered by the licence

Where Viedoc falls short

  • Hosting country not given
  • Legal form missing from the pages checked
  • Privacy policy allows transfers to the USA
  • No amounts shown

Standout feature. Viedoc offers a multiple licence model for concurrent studies, with hosting and support inside the fee.

#6 secuTrial

Berlin, Germany Not published; the vendor cites an attractive price model Demo on request

Best for: Academic trial units and registries with imaging data and changing form needs

  • Operating company. interActive Systems GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. Nuremberg (noris network NBG6 data centre)
  • Source code. Closed source
  • Replaces. Veeva Vault EDC, OpenClinica

secuTrial is a browser-based EDC that the vendor describes as GCP-compliant for clinical and non-interventional studies and patient registries. It lists seven randomization algorithms, double data entry for studies that begin on paper, pseudonymised image management with DICOM support, CDISC interfaces and patient apps for outcomes.

interActive Systems GmbH, whose imprint gives Glogauer Str. 19 in Berlin and register entry HRB 106103B at Berlin Charlottenburg, builds it. A news item says secuTrial and customer data are hosted at the noris network NBG6 facility in Nuremberg. According to the vendor, customer requests become functions through a validated process, and urgent ones can ship within weeks outside the release plan. Ownership and pricing are not stated.

What secuTrial does well

  • Berlin imprint with a register number
  • Hosting site named as Nuremberg
  • Choice of seven randomization methods
  • Handles DICOM images
  • Double entry supported for paper capture

Where secuTrial falls short

  • Prices not listed
  • Data capture only, no CTMS or eTMF
  • One hosting arrangement described
  • Owner not named

Standout feature. secuTrial manages pseudonymised DICOM images inside the EDC, which suits imaging endpoints.

#7 Ennov Clinical

Paris, France Founded 1999 Not published Demo on request

Best for: Organisations wanting CTMS, eTMF and EDC from one vendor, or an on-premises installation

  • Operating company. Ennov SAS
  • Jurisdiction. EU (France)
  • Where the data sits. Cloud or on-premises, region not stated
  • Source code. Closed source
  • Replaces. Veeva Vault Clinical, Veeva Vault CTMS, Veeva Vault eTMF

Ennov Clinical is the clinical range inside the Paris software house Ennov, covering CTMS, eTMF, EDC and RTSM. The CTMS handles oversight, monitoring and finances and calculates investigator payments from EDC data. The eTMF arrives with the TMF Reference Model structure, metadata-driven search and live QC status, and Ennov EDC offers no-code study design with built-in edit checks.

The privacy policy names Ennov SAS at 149 Avenue de France in Paris, the legal terms place the website under French law, and the About page dates the company to 1999. The vendor says more than 650 life sciences companies use Ennov. Cloud or on-premises deployment is possible, but regions are not stated, ownership is not described, and MACRO EDC and DataLabs EDC sit beside Ennov EDC without an explanation of how they relate.

What Ennov Clinical does well

  • Four clinical products from one supplier
  • Can be installed on the sponsor's own servers
  • French entity named in the privacy policy
  • eTMF preloaded with the reference model
  • EDC studies designed without code

Where Ennov Clinical falls short

  • Prices not published
  • Cloud regions not given
  • Three EDC products with unclear roles
  • Catalogue extends well past clinical work

Standout feature. Ennov Clinical is the only tool here that combines CTMS, eTMF and EDC with an on-premises deployment option.

#8 Alcedis Platforms

Giessen, Germany Not published Demo on request

Best for: Sponsors that want an eCRF built to order and a CRO in the same company

  • Operating company. Alcedis GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. In-house cloud computing centre in Germany
  • Source code. Closed source
  • Replaces. Veeva Vault EDC, Medidata Rave

Alcedis Platforms is the software side of a digital clinical research organisation in Giessen, and its eCRF is custom-built to the protocol, with ready plugins for common processes. Mobile apps collect participant data such as quality of life and show project managers study progress, and a REST API connects Alcedis with third-party systems.

Alcedis GmbH is entered as HRB 3169 and listed at Winchesterstr. 3. The company says it launched Germany's first eCRF in 1998, and the eCRF page states that databases and interfaces run in its in-house cloud computing centre in Germany. The timeline records acquisition by Huma Therapeutics in 2023, whose own site gives a London headquarters. No certificates or prices are named on the pages checked.

What Alcedis Platforms does well

  • Register entry in Giessen
  • Cloud centre owned by the company, in Germany
  • REST API for outside systems
  • Participant apps on mobile
  • Research experience since 1998

Where Alcedis Platforms falls short

  • Built to order, not self-service
  • No amounts shown
  • No certificates named
  • Software and CRO services come together

Standout feature. Alcedis builds each eCRF to the protocol and runs it in its own computing centre in Germany.

#9 BSI Life Sciences

Baden, Switzerland Founded 1996 Not published Demo on request

Best for: Sponsors whose gap is trial operations and the master file, not data capture

  • Operating company. BSI Business Systems Integration AG
  • Jurisdiction. Switzerland (adequacy decision, outside the EEA)
  • Where the data sits. Not stated on the pages checked
  • Source code. Closed source
  • Replaces. Veeva Vault CTMS, Veeva Vault eTMF

BSI Life Sciences sells a CTMS that bundles trial management, a master file, start-up, training and supply modules, and an eTMF that runs standalone or inside the CTMS. The TMF can follow the reference document structure or any other one by configuration, reporting and access rights are set the same way, and a standard API links existing systems.

The unit belongs to BSI Business Systems Integration AG, a private Swiss software company with offices in Baden (Täfernweg 1), Munich and New Jersey. The page says the firm has built software for over 25 years across Switzerland, Germany and the United States, with the life sciences range going back to 1996. Switzerland is outside the EU but counts as European here. No EDC, certification, hosting option or price appears on the pages checked.

What BSI Life Sciences does well

  • CTMS and eTMF sold apart or together
  • Start-up, training and supply modules
  • Standard API
  • Swiss company named on the site
  • TMF structure can be configured

Where BSI Life Sciences falls short

  • Does not offer EDC
  • Certifications not named
  • Hosting not described
  • Prices not published

Standout feature. BSI Life Sciences sells its eTMF either on its own or inside the CTMS, so a team can start with the master file.

#10 CRF.one

Zurich, Switzerland Not published Demo on request

Best for: Registries and patient-reported outcome studies, for instance in dermatology

  • Operating company. Swiss4ward GmbH
  • Jurisdiction. Switzerland (adequacy decision, outside the EEA)
  • Where the data sits. Switzerland and the EEA only
  • Source code. Closed source
  • Replaces. REDCap-style registries, Veeva Vault EDC for small studies

CRF.one is a questionnaire and registry tool with a dynamic builder for conditional logic and longitudinal assessments. The page names PRO instruments including PHQ-9, GAD-7 and DLQI, adds automated reminders, electronic informed consent, dashboards, CSV, Excel and PDF export, and role-based access, with a white-label option. It supports multi-centre and multi-country studies.

The Impressum lists Swiss4ward GmbH at Böcklinstrasse 35 in Zurich, which runs other platforms such as DermaCompass and Cyberderm next to consulting. The site says CRF.one is hosted exclusively in Switzerland and the EEA, meets GDPR Article 9 requirements for health data and comes with a Data Processing Agreement as standard. It makes no GCP or 21 CFR Part 11 claim, and has no randomization, CTMS or eTMF.

What CRF.one does well

  • Hosting restricted to Switzerland and the EEA
  • Data Processing Agreement supplied
  • PRO instruments listed by name
  • Consent handled electronically
  • Zurich company in the Impressum

Where CRF.one falls short

  • No validation claim for interventional studies
  • No randomization, CTMS or eTMF
  • No amounts shown
  • Small vendor with consulting alongside

Standout feature. CRF.one ships with a Data Processing Agreement as standard and hosts only in Switzerland and the EEA.

How do I choose between the European clinical data capture tools?

Start with the study type, because the tools split along it. Climedo and Viedoc fit regulated drug and device studies that need ePRO and eConsent. Marvin EDC suits teams whose statisticians work in CDISC structures. secuTrial and Alcedis Platforms come from German academic and CRO settings, and CRF.one fits questionnaire-based registries.

Then check three things in writing: where production data sits, which entity signs, and which validation evidence the vendor can hand over. Marvin EDC, secuTrial and Alcedis name German data centres. Castor, Viedoc and BSI Life Sciences do not state a region on the pages we checked, so the contract has to supply it.

How is clinical trial software priced in Europe?

Four models appear. Ledidi charges per seat per month for its base plans and then adds per-project trial features and a one-time startup cost. Climedo charges a monthly fee and a one-time set-up fee for each active study, with unlimited users. Viedoc offers a single study licence or a multiple licence model with hosting and support inside the fee. Castor sends an itemised fixed-scope proposal.

The rest, namely Marvin EDC, secuTrial, Ennov Clinical, Alcedis Platforms, BSI Life Sciences and CRF.one, publish no figures. For those, ask for a quote that separates licence, set-up, validation work and support, since services can exceed the licence in a custom build such as Alcedis or a Castor-led study.

Does a European vendor guarantee that trial data stays in Europe?

No. The vendor's seat and the hosting location are separate questions. Climedo and Ledidi both run on AWS regions in Frankfurt, so a US-parented cloud sits beneath a European contract. Viedoc has a subsidiary in Raleigh and its privacy policy mentions transfers to the USA, and BSI Life Sciences lists an office in New Jersey.

Vendors that name European data centres themselves are Marvin EDC (Noris Network and Hetzner), secuTrial (noris network in Nuremberg), Alcedis (in-house centre in Germany) and CRF.one (Switzerland and the EEA only). Ask each one for the sub-processor list and for the clause that governs transfers outside the EEA.

Which tools replace Veeva Vault EDC, CTMS and eTMF?

For EDC, the tool pages list Climedo, Marvin EDC, Ledidi, Castor, Viedoc, secuTrial and Alcedis Platforms as replacements for Veeva Vault EDC or Medidata Rave. For the operations side, Ennov Clinical is listed against Veeva Vault CTMS and eTMF, and BSI Life Sciences against Veeva Vault CTMS and eTMF as well.

Viedoc lists an eTMF beside its EDC, but no European vendor here matches the full Veeva range in one product except Ennov Clinical, whose catalogue spans CTMS, eTMF, EDC and RTSM. Expect two contracts if you split capture and operations, for example Marvin EDC with Ennov Clinical, and agree on how study identifiers pass between them.

When should a sponsor not switch away from its current system?

When a study is already running, the cost of revalidation and retraining normally outweighs the gain. Switch at the next study start, not in the middle of one. Also hold back if you depend on one vendor for every module and the European option covers only half of them: BSI Life Sciences has no EDC, and Climedo, Ledidi and secuTrial have no CTMS or eTMF.

A second reason to wait is missing evidence. Marvin EDC describes its GCP and 21 CFR Part 11 compliance as a statement, and CRF.one makes no validation claim for interventional trials. If your quality unit requires a validation package and the vendor cannot send one, the legal comfort of a European entity does not close that gap.

How do the tools connect to other systems?

Marvin EDC integrates through APIs or a vendor-built Data Hub, Alcedis exposes a REST API, Castor an open API and Viedoc a Viedoc API. BSI Life Sciences offers a standard API for its CTMS and eTMF, and secuTrial lists CDISC interfaces. Ennov Clinical connects ePRO and covers randomization inside its own RTSM.

Integration is where hidden cost sits. A CTMS that takes investigator payments from EDC data, as the Ennov CTMS does, only works if both modules are from the same vendor or the interface has been built. Ask each vendor for the interface specification before you sign, and for who pays when the other side changes its format.

How we selected and ranked these 10 tools

Every tool on this page is in the European Purpose directory, which means the operating company is established in Europe and we have verified that from the company register or the vendor's own legal notice rather than from a marketing page. Tools headquartered outside Europe are not eligible, however good they are.

  1. Feature verification (weight: 40%). We check each capability against the vendor's own documentation and product pages, and record what the tool does rather than what the category is assumed to include.
  2. Ease of adoption (weight: 30%). Integrations, published API access, trial availability and how much configuration stands between signing and a usable result.
  3. Value and transparency (weight: 30%). Published pricing counts in a vendor's favour; quote-only pricing is recorded as quote-only rather than estimated. We weigh what a buyer gets for the entry price, not the headline feature count.
  4. Editorial review. Every page is researched and drafted with AI assistance, and the compliance and pricing claims are checked against the vendor's documentation before it is published under the founder's editorial responsibility. The three weights above decide the order; a position is a ranking against the other European tools in this category, not an absolute score.

Vendor-reported outcomes — ROI figures, margin uplift, time saved — are labelled as vendor claims wherever they appear on this page. We have not audited them, and neither has anyone else who quotes them. Read our full editorial process for how pages are re-verified.

Frequently asked questions

No single tool wins every criterion. Climedo, Marvin EDC, Viedoc and Castor lead on EDC with ePRO and eConsent, Ledidi on published euro prices, and Ennov Clinical on breadth across CTMS, eTMF and EDC. BSI Life Sciences is the choice for CTMS and eTMF without EDC, and CRF.one suits questionnaire-based registries hosted in Switzerland and the EEA.

Only Ledidi shows figures: EUR 10, EUR 25 and EUR 45 per seat per month on annual billing for the base plans. Climedo and Viedoc describe how they charge, per active study or by licence model, without amounts, and Castor works through an itemised proposal. The other six tools give no price on the pages we checked.

Marvin EDC names Noris Network and Hetzner in Germany, secuTrial names noris network in Nuremberg, Alcedis names its own centre in Germany, Climedo and Ledidi name AWS Frankfurt, and CRF.one says Switzerland and the EEA. Castor, Viedoc, Ennov Clinical and BSI Life Sciences do not state a region on the pages we checked.

Both count as European in this directory. Ledidi is a Norwegian company in the EEA, and BSI Life Sciences and CRF.one are Swiss, covered by an adequacy decision but outside the EEA. If your sponsor rules require an EU entity, filter for the German, Dutch, Swedish and French vendors.

Ennov Clinical comes closest, with CTMS, eTMF, EDC and RTSM in its catalogue, and Viedoc lists EDC, ePRO, randomization, supply management and an eTMF. Most others cover only data capture or only operations, so a two-vendor set-up is the usual result of leaving Veeva.
