Find real registered clinical trials
Ask about trials for a condition, drug, or intervention and Zeplik searches the live public trials registry, then answers with real studies, their NCT identifiers, phase, and recruitment status. This matters because a language model on its own will invent a trial, an identifier, or a status that reads as authoritative and is entirely fabricated. Here every study is grounded in a real registry record, and when nothing matches Zeplik says so plainly rather than manufacturing a trial that does not exist.
The lookup is free; you pay only the normal cost of the answer, shown before you send.
How it works
Name the condition or intervention
Ask in plain language, like 'recruiting trials for type 2 diabetes' or 'phase 3 studies of a GLP-1 drug'. A condition, drug, or intervention is enough for Zeplik to run the search.
Zeplik searches the live registry
It queries the live public clinical-trials registry, not the model's memory, and treats each result as source material handled as untrusted content, so nothing in a record can hijack the answer.
Read the grounded record and verify
The answer returns real trials with their NCT id, phase, and status, so you can open the registry entry, confirm the details, and ask follow-ups in the same conversation.
Worked examples
Real prompts you can open in the composer with the text ready to review. Nothing sends on its own. Swap in your own details.
Prompt: Find recruiting clinical trials for early-stage Alzheimer's disease
Zeplik searches the live registry and returns real studies with their NCT ids and status, so you start from records that exist rather than an invented list.
Open this in ZeplikPrompt: What phase 3 trials are testing semaglutide, and what is each one's status?
It grounds an intervention search in real registry records, each with its phase and recruitment status, instead of a confident guess.
Open this in ZeplikPrompt: Someone mentioned trial NCT01234567. Can you verify it exists and tell me what it studies?
Verification is the point: it checks whether the identifier resolves to a real trial and tells you plainly if it cannot be confirmed.
Open this in ZeplikWhat it can and cannot do
The lookup is precise about what it can verify and honest about its edges. Here is the plain posture.
Search the live registry by disease, drug, or intervention and get real registered studies.
Each result comes back with its real identifier, trial phase, and recruitment status, so you can locate and confirm it.
Paste an NCT id and Zeplik checks whether it resolves to a real trial, catching fabricated or garbled references.
If no trial matches, Zeplik says so plainly instead of inventing an authoritative-looking study.
It finds and cites registered trials; it does not advise on treatment or decide whether you qualify. Discuss any trial with a qualified clinician.
It reports what the public registry holds. A study that was never registered cannot be looked up here.
Grounded, and honest by default
- It cites real registry records. Every trial comes back with its real NCT identifier, phase, and status, so you can verify each one at the source instead of trusting the model's memory.
- It will not invent a trial. When nothing matches or an identifier cannot be confirmed, Zeplik says so rather than fabricating a plausible-looking study.
- Record text cannot hijack the answer. Each registry record is treated as untrusted content: Zeplik reads and reports it but never obeys instructions embedded inside it.
Frequently asked questions
- Why not just ask a chatbot about clinical trials?
- Because a language model on its own can invent trial names, identifiers, and statuses that read as authoritative and do not exist. This tool searches the live public registry and returns real records you can verify, and it refuses to fabricate a study when nothing matches.
- Which registry does it search?
- It queries the live public clinical-trials registry. Give a condition, drug, or intervention and Zeplik returns matching registered studies with their NCT identifiers, phase, and recruitment status.
- Can it verify a trial identifier I have?
- Yes. Paste an NCT id and Zeplik checks whether it resolves to a real trial and summarizes what it studies, so you can catch a fabricated or mistyped reference.
- Is this medical advice?
- No. It finds and cites registered trials so you can locate and confirm them, but it does not advise on treatment or determine your eligibility. Discuss any trial with a qualified clinician. Zeplik is clear about this boundary.
- Does the search cost credits?
- The trials lookup itself is free. You pay only the normal model-token cost of the answer written around it, shown before you send, like any other message.
