Registered clinical trials with phases, status and readout dates

About
ClinicalTrials.gov is the U.S. National Library of Medicine's registry of clinical studies, where sponsors must register most trials of drugs, biologics and devices. For a biotech or pharma name, this is the pipeline as the sponsor registered it: each trial's phase, status, conditions and enrolment, plus the primary completion date that sets when results are due. Open a trial for its design, endpoints and any posted results.
Trials are matched to sponsors by name, so ones run by a partner or subsidiary can be missed. Estimated dates are the sponsor's own projection, and they move often.
Nothing to set up and no key to bring. Marvin Labs runs this connector, so it is on unless you turn it off under Connectors in settings.

Frequently asked questions
- What is a Connector?
- A Connector is an MCP server that Marvin Labs runs and authenticates. There is no URL to paste and no key to find: ClinicalTrials.gov is on for your account unless you turn it off. AI Analyst Chat and Deep Research Agents call its tools when a question needs them, and the answer shows which tool was called and what it returned.
- Does the ClinicalTrials.gov Connector require authentication?
- No. Marvin Labs holds the ClinicalTrials.gov credentials and signs every request, so there is nothing to set up.
- Does ClinicalTrials.gov change how financial data is sourced?
- No. When a question can be answered from the filings, earnings calls, and press releases Marvin Labs ingests through Automated Data Import, it answers from those. ClinicalTrials.gov is used only when a question needs data those documents do not carry, and the answer attributes that output to it.
- Where is ClinicalTrials.gov available?
- In both AI Analyst Chat and Deep Research Agents. Its tools stay out of the model's context until a request needs one, so an unused Connector takes up no context window.
