Monoclonal Antibody Pharmacovigilance HTTP Interface and

Data Characteristics for This Category

Adverse event data for monoclonal antibody drugs typically originates from clinical trial reports, real-world studies, post-market surveillance systems (e.g., FDA Adverse Event Reporting System, FAERS), and literature reviews. Data update frequencies vary; clinical trial data is relatively stable, while post-market surveillance data flows continuously. Document structures are diverse, including structured reports (e.g., CIOMS I forms, MedWatch forms), semi-structured text (e.g., medical records, case reports), and unstructured descriptions (e.g., physician notes). Beyond standard patient information, drug details, event descriptions, and prognoses, specific fields of interest include antibody type (e.g., IgG1, IgG4), target (e.g., PD-1, TNF-α), administration route, concomitant medications, and immunogenicity-related indicators (e.g., anti-drug antibody test results). Units commonly include mg/kg or mg for dosage, and days, weeks, months for time.

Constraints Imposed by These Characteristics on "HTTP Interface and External Systems"

The diversity and complexity of monoclonal antibody adverse event data place specific demands on FastGPT's HTTP interface and external system integration. The presence of semi-structured and unstructured text necessitates robust text parsing capabilities to accurately extract key field information. Identifying unique fields like antibody type and target requires flexible mapping of HTTP request parameters to specific query fields in external systems. The continuous nature of data updates, especially for post-market surveillance, dictates that interface calling strategies must support periodic or event-driven synchronization mechanisms. Additionally, since data sources may be distributed across multiple platforms, the interface needs to handle various authentication methods (e.g., API Key, OAuth 2.0) and data formats (e.g., JSON, XML). Standardized handling of dosage and time units is also crucial for ensuring data consistency and accuracy.

Configuration Settings

Configuration Item	Recommended Approach	Rationale
`HTTP Method`	`POST` or `GET`	Based on external system API documentation requirements; `POST` for submitting data, `GET` for querying.
`Content-Type`	`application/json`	External systems widely use `JSON` format for data exchange, facilitating parsing.
`Timeout`	`600 seconds`	External system response times can be long when processing complex queries or large datasets.
`Headers.Authorization`	`Bearer <YOUR_API_KEY>`	Most external systems use `Bearer Token` or `API Key` for authentication.
`Request Body`	Construct a `JSON` object according to external system API documentation	Ensure field names and data types in the request body match external system definitions, for example, including `antibody_type`, `target_molecule` fields.
`Response Field Mapping`	Map external system's `adverse_event_description` to `event_text`	Map key information returned by the external system to FastGPT's internal fields for subsequent processing.

Three Common Mistakes

An HTTP request returns a 400 Bad Request error because the antibody_type field value in the request body does not conform to the external system's expected enumeration list.
Text returned by the HTTP API node in a workflow is truncated, leading to incomplete subsequent segmentation and sending. This occurs because the max_response_length parameter is set too low, failing to receive the full, lengthy adverse event description from the external system.
Frequent calls to the external system interface result in a 429 Too Many Requests status code. This happens when an appropriate rate limit or retry interval is not configured, exceeding the external system's allowed call frequency.

How to Confirm Proper Configuration

In FastGPT's HTTP API configuration interface, test with actual monoclonal antibody adverse event query parameters. Check if the returned status code is 200 OK.
Verify that key fields, such as event_text, antibody_type, and target_molecule, in the HTTP API's returned JSON data contain the expected content and that their data formats are correct.
In a FastGPT workflow, connect the HTTP API node's output to a text parsing or knowledge base storage node. Check if the parsed data accurately extracts detailed adverse event information and relevant biological characteristics.
