DIC03-TriPhar (TREE)

TREE is an AI-backed decision-support dashboard for pharmaceutical development. It helps discovery, clinical, and operations teams explore literature, clinical trials, pipeline data, regulatory alerts, and document analysis through a single interface—with live external APIs and optional LLM summarization.


What It Does

  • Statistics — Search and explore clinical-trial and literature data with filters and visualisations.
  • Insights (Decision Support Hub) — Pipeline monitoring (ClinicalTrials.gov–style), clinical document upload and AI summarisation (DeepSeek), side-by-side comparison of PDFs, and regulatory alerts / compliance-style reports.
  • Trends — Predictions and trend views over merged medical/legal data.
  • Research AI — Natural-language chat over TREE (query, role-aware summaries, citations). Optional streaming; chat history persisted per session.

External data is live API–only (no bulk download or storage of PubMed/ClinicalTrials.gov etc.); optional persistence is minimal (e.g. chat history, merged DB for analytics). See docs/DATA-HANDLING.md and docs/TREE-ARCHITECTURE.md for constraints and design.


Workflow

  1. User — Logs in, picks a section (Statistics, Insights, Trends, Research AI) from the nav.
  2. Frontend — Next.js app (React). All API calls go to /api/*, which Next rewrites to the backend.
  3. Proxy — Next.js rewrites /api/:path* → http://127.0.0.1:8000/api/:path* (long requests use an increased proxy timeout).
  4. Backend — FastAPI on port 8000: auth/CORS, routing, validation. Uses adapters for PubMed, ClinicalTrials.gov, merged DB, regulatory sources; DeepSeek for document summarisation, comparison, chat, and compliance summaries.
  5. Data — Live API calls per request; optional SQLite DBs under data/ (e.g. merged medical data, legal/regulatory) for analytics and insights. No storage of full external API payloads.
  6. Response — JSON (or stream) back to the frontend; UI renders tables, charts, markdown, and chat.

Quick Start

  1. Backend (from repo root):

    cd backend
    python -m venv .venv
    .venv\Scripts\activate   # Windows
    pip install -r requirements.txt
    cd ..
    uvicorn backend.app.main:app --reload --host 0.0.0.0 --port 8000
  2. Frontend:

    npm install
    npm run dev
    • App: http://localhost:3000 (or the port Next prints).
    • Set DEEPSEEK_API_KEY in backend/.env for PDF summarisation, chat, and compliance LLM features.
  3. Optional — Ensure data/merged_medical_data.db (and any other DBs your flows need) exist if you use pipeline/trends features that depend on them.

For more detail (endpoints, env, data rules), see backend/README.md and git**docs/**.
