About
Background
InTxGNN is a research-support platform for drug repurposing, built on the TxGNN model published in Nature Medicine by the Zitnik Lab at Harvard University. It predicts indication expansion for medicines approved by CDSCO in India. Beyond AI prediction scores, the platform integrates clinical evidence from ClinicalTrials.gov and PubMed so researchers can quickly assess how credible each prediction is.
About the Developer
This platform is developed and operated by 藥提醒科技有限公司 (yao.care, company registration number 83620786, 12F, No. 220, Sec. 2, Taiwan Blvd., West Dist., Taichung City, Taiwan).
InTxGNN is the India site of the company’s “TxGNN Drug Repurposing” product line.
The same system is deployed across 30 countries and regions, each named {CC}TxGNN
(JpTxGNN, UsTxGNN, DETxGNN, and so on) at {cc}txgnn.yao.care.

The TxGNN model itself was developed by the Zitnik Lab at Harvard Medical School and published in Nature Medicine. This platform is the production system 藥提醒科技有限公司 built on top of that model, covering national drug-registration data integration, dual knowledge-graph and deep-learning prediction, PubMed / ClinicalTrials evidence grading, and SMART on FHIR electronic health record integration.
What is drug repurposing?
Drug repurposing means finding new therapeutic uses for existing medicines. Compared with developing a new drug from scratch — 10 to 15 years and USD 1–2 billion — repurposing takes 3 to 5 years and USD 100–300 million, and human safety data already exists, so the risk of failure is lower.
| Aspect | New drug development | Drug repurposing |
|---|---|---|
| Time | 10–15 years | 3–5 years |
| Cost | USD 1–2 billion | USD 100–300 million |
| Safety data | Must be established | Human data already available |
| Risk of failure | Very high (>90%) | Lower |
What is TxGNN?
TxGNN is a deep learning model developed by the Zitnik Lab at Harvard Medical School and published in Nature Medicine. It predicts novel drug–disease associations and is the first foundation model for drug repurposing designed specifically for clinicians.
"TxGNN integrates a knowledge graph of 17,080 biomedical entities and uses graph neural networks to learn complex relationships between nodes, predicting potential efficacy of drugs against rare diseases." — Huang et al., Nature Medicine (2023)
