Capture vs Suvoda: follow the data, not the feature list
Suvoda is a specialist IRT. Capture runs randomization, blinding and kits inside the EDC. Tracing how a participant's allocation, kits and visit data flow through each setup shows which your study needs.

Capture vs Suvoda: the short version
- Suvoda is best known for interactive response technology (IRT) for randomization and trial supply management, particularly in complex trials.
- A standalone IRT and an EDC exchange participant, allocation and dispensing data; each exchange is something to specify, test and reconcile.
- In Capture, allocation, kits and visit data are one record.
- Capture supports stratification, enrolment caps, blinded roles, emergency unblinding and kit accountability.
- Complex depot networks and forecasting may still justify a specialist IRT.

The comparison
Trace one participant through each setup
Pick one participant and follow them: screened and enrolled in the EDC, randomized in the IRT, kit assigned, visit data entered, kit returned. In a two-system setup, each step crosses the integration; mismatches such as a participant randomized in one system but missing in the other are a familiar monitoring finding.
In Capture the same participant is randomized at enrolment in the EDC, their allocation is logged in the audit trail, kits are dispensed under e-signature, and blinded users never see the arm. See the Suvoda alternatives guide for the supply-chain side of the decision.
What to compare
What to test when comparing Capture and Suvoda
| Criterion | Why it matters | Capture |
|---|---|---|
| Randomization design | Balance and allocation concealment | Block randomization with stratification and enrolment caps |
| Blinding | Protecting the trial | Blinded roles never receive the treatment arm, including in exports |
| Emergency unblinding | Participant safety | Available to investigators; approvals without revealing the arm; logged |
| Kit management | Dispensing and accountability | Kit dispensing under e-signature; accountability report and export |
| Data flow | Reconciliation effort | Allocation, kits and visit data in one participant record |
| Complex supply | Depots, forecasting, resupply | Map requirements; very complex supply may need a specialist IRT |
This table shows Capture's answers only. Ask Suvoda for theirs, and confirm current capabilities and terms directly with them.
Randomization
Randomization and kits inside the EDC
Set arms, block size, stratification factors and enrolment caps once at setup. Allocation happens at enrolment, the same way at every site, and is logged in the audit trail. An unblinded administrator owns the randomization and medication lists, and kits are dispensed under electronic signature.
- Stratified block randomization with caps.
- Kit dispensing and accountability.
- Allocation logged in the audit trail.

Blinding
Blinding enforced on the server
Blinded roles never receive the treatment arm, not even in the data behind the screen or in exports. Investigators keep emergency unblinding, and the study owner can approve an unblinding request without seeing the answer. Every allocation and unblinding is logged.
- Treatment arm never sent to blinded users.
- Emergency unblinding, logged.
- Approvals without revealing the arm.

Fit
When Suvoda fits, and when Capture does
Suvoda is often the right choice for complex global trials with many depots, forecasting, temperature-controlled supply and sophisticated resupply rules.
Capture fits studies with straightforward supply that want randomization, blinding and kit accountability without a second system to integrate.
One platform
EDC, ePRO, eConsent and randomization in one study
Sites enter data on locked, approved forms with edit checks that raise queries at entry. Participants complete questionnaires on their own phones and sign eConsent with verified signatures. Randomization and kit management run in the same study, and everything shares one field-level audit trail.
- One participant record across every module.
- No integrations to build or reconcile.
- Phase 1 through Phase 3.
Switching
Moving from Suvoda to Capture
Recreate the randomization design in Capture for new studies rather than moving live lists. Keep completed studies' allocation records with their original exports.
Before choosing, write down your supply requirements: depots, kit types, temperature control and resupply. If they are simple, randomization in the EDC is usually enough.

All comparisons
Compare Capture with other platforms
Every comparison uses the same approach: what to test, where each option fits, and Capture's own answers. See all of them on the comparisons hub at /compare.
Can Capture replace a standalone IRT?
For many studies, yes. Very complex global supply chains may still need a specialist IRT.
Is allocation concealed?
Yes. Blinded roles never receive the treatment arm, and an unblinded administrator owns the lists.
Can enrolment be capped?
Yes. Enrolment caps are part of the randomization setup.
Can I test Capture before deciding against Suvoda?
Yes. The free sandbox includes every feature with sample data, no credit card and no time limit. You pay only when you go live.
How did you build this comparison?
From public positioning and the criteria teams tell us matter. We state only Capture's own capabilities as fact; confirm Suvoda's current offering with them.
