## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Clinical Trials Watch — New & Updated Studies (ClinicalTrials.gov)

**Know when a trial starts, changes or opens recruitment — the day it happens.** One call per watched query: new and updated clinical trials by condition, sponsor or drug name, with phase, status, enrollment, interventions and countries as clean JSON, straight from the official ClinicalTrials.gov API.

Trial intelligence platforms charge thousands per seat. The raw signal — who is trialing what, in which phase, updated when — is public data. This Actor structures it for the price of an API call.

### What you get per watched query

```json
{
  "query": { "condition": "melanoma", "sponsor": null, "term": null },
  "totalInSource": 472,
  "returned": 100,
  "studies": [
    {
      "nctId": "NCT03698019",
      "title": "A Study to Compare the Administration of Pembrolizumab...",
      "status": "RECRUITING",
      "studyType": "INTERVENTIONAL",
      "phases": ["PHASE2"],
      "conditions": ["Melanoma"],
      "interventions": ["Pembrolizumab"],
      "sponsor": "National Cancer Institute (NCI)",
      "sponsorClass": "NIH",
      "enrollment": 850,
      "startDate": "2018-11-05",
      "lastUpdate": "2026-07-02",
      "countries": ["United States", "Canada"],
      "siteCount": 124,
      "url": "https://clinicaltrials.gov/study/NCT03698019"
    }
  ]
}
```

### Built for recurring watch

- **`updatedSince` + a schedule** = a rolling feed of only what changed: new trials, status flips, enrollment updates.
- **Watch by what matters to you**: a condition ("alzheimer"), a competitor sponsor ("Pfizer"), or a drug/mechanism as free term ("GLP-1").
- **Status pre-filtered**: default `RECRUITING` + `NOT_YET_RECRUITING` — the actionable window; ask for `TERMINATED`/`SUSPENDED` to catch failures early.
- **Batch watchlists**: up to 25 queries per run with per-query overrides.

### Use cases

- **Biotech BD / competitive intelligence**: every new trial your competitors register, weekly.
- **Investors**: phase transitions and terminations are tradeable events — see them structured.
- **CROs / site networks**: new studies recruiting in your therapeutic areas and countries.
- **Patient advocates**: trials opening for a condition, with sites and countries.
- **AI agents**: "any new phase-3 trials for X since Monday?" — one tool call.

### Input

| Field | Description |
|---|---|
| `condition` / `sponsor` / `term` | What to watch (combine or use `queries` for a watchlist) |
| `queries` | Up to 25 watches per run |
| `statuses` | Default `["RECRUITING", "NOT_YET_RECRUITING"]`; empty = all |
| `updatedSince` | YYYY-MM-DD — only studies updated on/after this date |
| `maxStudiesPerQuery` | Cap per query (default 100, max 1000) |

### Use with AI agents (MCP)

This Actor is exposed as a tool on the [Apify MCP Server](https://mcp.apify.com):

```json
{
  "mcpServers": {
    "clinical-trials-watch": {
      "url": "https://mcp.apify.com?tools=jdepablos/clinical-trials-watch",
      "headers": { "Authorization": "Bearer <APIFY_TOKEN>" }
    }
  }
}
```

### Pricing

Pay per event: **one flat fee per watched query scanned** — all matching studies in your window included. Failed queries are never charged.

### FAQ

**Is this medical advice?** No. It is structured public registry data from the official U.S. National Library of Medicine API.

**How fresh is it?** ClinicalTrials.gov updates continuously; sponsors must post updates within strict windows. The Actor reads the live API.

**Non-US trials?** Yes — ClinicalTrials.gov includes trials worldwide (sites in 200+ countries), and `countries` is included per study.
