## 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

## ClinicalTrials.gov Scraper — Studies & Trials

Search and extract clinical trial data from **ClinicalTrials.gov** — the US National Library
of Medicine's registry of 500,000+ studies. Filter by condition, intervention, sponsor,
keyword or recruitment status, and get clean structured data per study.

Built on the official ClinicalTrials.gov **v2 API** — free, public, no key, no anti-bot.

### Who it's for

- **Pharma & biotech competitive intelligence** — track trials by drug, sponsor or indication.
- **CROs** — site selection, enrollment and status monitoring.
- **Investors & analysts** — follow pipeline progress and phase transitions.
- **Researchers & AI pipelines** — structured trial metadata at scale.

### Input

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `condition` | string | — | Condition/disease, e.g. `diabetes` |
| `intervention` | string | — | Drug/treatment, e.g. `semaglutide` |
| `sponsor` | string | — | Lead sponsor/collaborator, e.g. `Pfizer` |
| `searchTerm` | string | — | Free-text search across fields |
| `status` | array | — | Filter by status: `RECRUITING`, `ACTIVE_NOT_RECRUITING`, `COMPLETED`, `TERMINATED`, … |
| `maxResults` | integer | `200` | Cap on studies returned |

Provide at least one of `condition`, `intervention`, `sponsor` or `searchTerm`.

### Output

One row per study:

```json
{
  "nctId": "NCT07091500",
  "title": "GLP-1 Receptor Agonist for Obesity",
  "status": "RECRUITING",
  "phases": ["PHASE2"],
  "studyType": "INTERVENTIONAL",
  "enrollment": 40,
  "startDate": "2026-01-15",
  "completionDate": "2027-06-30",
  "lastUpdateDate": "2026-07-01",
  "leadSponsor": "Washington University School of Medicine",
  "collaborators": ["…"],
  "conditions": ["Obesity"],
  "interventions": ["DRUG: Semaglutide"],
  "sex": "ALL",
  "minAge": "18 Years",
  "maxAge": "65 Years",
  "locationCount": 12,
  "countries": ["United States"],
  "url": "https://clinicaltrials.gov/study/NCT07091500"
}
```

### Notes & limits

- Official ClinicalTrials.gov v2 API — free, public, no key or anti-bot; paginated automatically.
- For advanced field-level queries, use the `searchTerm` field (supports the API's expression
  syntax) alongside `condition`/`intervention`/`sponsor`.
- Public data; you are responsible for compliant use of the output.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "condition": "diabetes"
};

// Run the Actor and wait for it to finish
const run = await client.actor("ponderable_hydrometer/clinicaltrials-scraper").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});
