## Pricing

from $1.00 / 1,000 results

This Actor is paid per event and usage. You are charged both the fixed price for specific events and for Apify platform usage.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).


# README

## ClinicalTrials.gov Studies Extractor

Extract clinical-trial records from **ClinicalTrials.gov (API v2)** — one **study per row** — filtered by condition, intervention/term, or trial status. Ideal for pipeline tracking, catalyst calendars, and competitive intelligence.

Built for biotech/pharma investors and analysts, CROs, and life-science researchers.

---

### Why use this actor

- **Whole corpus or a slice** — 588k+ studies; pull everything via cursor pagination, or filter to your therapeutic area.
- **One study per row**, with a flat header (`nct_id`, `brief_title`, `overall_status`, `phase`, `lead_sponsor`, `start_date`) plus the **full raw study object** (protocol, derived, results) preserved.
- **No login, no key.** Clean JSON API.

### Input

| Field | Type | Description |
| --- | --- | --- |
| `conditionQuery` | text | Disease/condition, e.g. `breast cancer`. |
| `termQuery` | text | Other terms (drug, sponsor, keyword). |
| `status` | **multi-select** | Filter by overall status (Recruiting, Completed, Terminated, …). |
| `pageSize` | int | 1–1000 (default 1000). |
| `maxItems` | int | 0 = all matching. |

`status` is a **dropdown of the valid ClinicalTrials statuses** — no need to know the API enum strings.

### Output — `CLINICAL_TRIAL`

Envelope (`_input`, `_source`, `_scrapedAt`) + `recordType: "CLINICAL_TRIAL"` + flat header fields, then the raw study object verbatim:

```json
{
  "_input": "cond=breast cancer; status=RECRUITING",
  "_source": "S1-ctgov-v2",
  "_scrapedAt": "2026-06-03T10:00:00Z",
  "recordType": "CLINICAL_TRIAL",
  "nct_id": "NCT01234567",
  "brief_title": "...",
  "overall_status": "RECRUITING",
  "phase": "PHASE2",
  "lead_sponsor": "...",
  "start_date": "2026-01-01",
  "protocolSection": { "...": "..." },
  "derivedSection": { "...": "..." },
  "hasResults": false
}
````

### How it works

1. Your filters become v2 query params (`query.cond`, `query.term`, `filter.overallStatus`).
2. The actor pages through results with the `nextPageToken` cursor (pageSize up to 1000).
3. Each study streams into the dataset.

### Known limits

- Public API, no WAF; datacenter IP is fine. Backs off on HTTP 429.
- **Verified live 2026-06-03:** totalCount 588,273; cursor pagination via `nextPageToken` confirmed.

# Actor input Schema

## `conditionQuery` (type: `string`):

Optional. e.g. 'breast cancer', 'type 2 diabetes'. Leave blank for all conditions.

## `termQuery` (type: `string`):

Optional free-text, e.g. a drug name or sponsor.

## `status` (type: `array`):

Optional. Filter by one or more overall statuses. Leave empty for any status.

## `pageSize` (type: `integer`):

How many records to fetch per request.

## `maxItems` (type: `integer`):

Maximum records to return (0 = all matching).

## `proxyConfiguration` (type: `object`):

Not required (public API).

## Actor input object example

```json
{
  "conditionQuery": "",
  "termQuery": "",
  "status": [],
  "pageSize": 1000,
  "maxItems": 0,
  "proxyConfiguration": {
    "useApifyProxy": false
  }
}
```

# 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 = {};

// Run the Actor and wait for it to finish
const run = await client.actor("xtracto/clinicaltrials-studies").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);
});

# Prepare the Actor input
run_input = {}

# Run the Actor and wait for it to finish
run = client.actor("xtracto/clinicaltrials-studies").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print("💾 Check your data here: https://console.apify.com/storage/datasets/" + run["defaultDatasetId"])
