TIVOZANIB: From Renal Cell Carcinoma to Endocervical Carcinoma
One-Sentence Summary
Tivozanib is a highly selective VEGFR-1/2/3 tyrosine kinase inhibitor originally approved for renal cell carcinoma. The TxGNN model predicts it may be effective for Endocervical Carcinoma, with 0 clinical trials and 0 publications currently supporting this direction — this is a pure model prediction.
Quick Overview
| Item | Content |
|---|---|
| Original Indication | Renal Cell Carcinoma (per known approval history; no local license record available) |
| Predicted New Indication | Endocervical Carcinoma |
| TxGNN Prediction Score | 99.81% |
| Evidence Level | L5 |
| US Market Status | Not Marketed (未上市) |
| Number of NDAs | 0 |
| Recommended Decision | Hold |
Why is This Prediction Reasonable?
Currently, structured mechanism-of-action data is not available in the evidence pack (flagged as a data gap). However, the repurposing rationale indicates that tivozanib is a highly selective VEGFR-1/2/3 tyrosine kinase inhibitor already approved for renal cell carcinoma, acting through inhibition of angiogenesis.
The proposed link to endocervical carcinoma rests on the general biological plausibility that anti-angiogenic therapy can be active across VEGF-driven tumor types — an analogy drawn to bevacizumab’s established role in cervical cancer. However, this rationale is not specific to endocervical adenocarcinoma, and no direct clinical or preclinical evidence exists for this particular histologic subtype.
For the remaining nine candidates (ranks 2–10, all rare uterine ligament/cervical adenocarcinoma variants), the evidence pack explicitly notes that these are extremely rare tumor entities with no biomarker, epidemiological, or treatment-response literature — the association derives solely from knowledge-graph embedding similarity, not biological validation.
Clinical Trial Evidence
Currently no related clinical trials registered.
Literature Evidence
Currently no related literature available.
US Market Information
Tivozanib currently has no marketing authorization records in this jurisdiction (market status: 未上市 / Not Marketed; total licenses: 0). No license table can be generated from available data.
Cytotoxicity
Tivozanib is an antineoplastic agent (VEGFR-1/2/3 tyrosine kinase inhibitor, approved for renal cell carcinoma), so this section applies.

Conclusion and Next Steps
Decision: Hold
Rationale: All 10 predicted indications are supported only by TxGNN model scores (L5 evidence) with zero clinical trials or literature. Additionally, a Blocking data gap exists for local warnings/contraindications (DG001), and the drug is not currently marketed in this jurisdiction, preventing any safety pre-screening (S1).
To proceed, the following is needed:
- Local (e.g., TFDA) label PDF with warnings, contraindications, and precautions (resolve DG001)
- Structured mechanism-of-action data via DrugBank API (resolve DG002)
- Primary literature or preclinical data specifically evaluating VEGFR inhibition in endocervical/cervical adenocarcinoma subtypes
- Confirmation of drug availability/import pathway given current “not marketed” status
