Solifenacin: From Overactive Bladder to Polycystic Kidney Disease 3 (with or without Polycystic Liver Disease)
One-Sentence Summary
Solifenacin is a selective M3 muscarinic antagonist used for bladder symptoms. The TxGNN model predicts it may be effective for polycystic kidney disease 3 with or without polycystic liver disease, but there are 0 clinical trials and 20 publications, all disease-background reviews or guidelines. None of them evaluates solifenacin, so this prediction is a knowledge-graph association only.
Quick Overview
| Item | Content |
|---|---|
| Original Indication | Overactive bladder (inferred from the drug’s class and pharmacology; the SAHPRA registration record gives no indication text) |
| Predicted New Indication | Polycystic kidney disease 3 with or without polycystic liver disease |
| TxGNN Prediction Score | 97.13% |
| Evidence Level | L5 |
| South Africa Market Status | Marketed |
| Number of SAHPRA Registrations | 1 |
| Recommended Decision | Hold |
Why is This Prediction Reasonable?
It is not well supported. Currently, detailed mechanism of action data is not available in the record. Solifenacin is known to block M3 muscarinic receptors on bladder smooth muscle, which reduces involuntary detrusor contractions.
Polycystic kidney disease 3 with or without polycystic liver disease is a genetic disease (GANAB-related). Cyst formation is driven by defects in polycystin and ER glycoprotein processing. No plausible link exists between muscarinic receptor antagonism and these pathways.
The high score of 0.97 reflects a graph association, not a biological rationale or clinical signal. The 20 retrieved publications describe the disease’s genetics, diagnosis and management, and none evaluates solifenacin.
Clinical Trial Evidence
Currently no related clinical trials registered.
Literature Evidence
No study among the retrieved publications tests solifenacin. All are background literature on the disease.

Conclusion and Next Steps
Decision: Hold
Rationale: The prediction has no clinical trials, no drug-specific literature and no plausible mechanistic link, so it stays at L5 (model prediction only). The other nine predictions for this drug are also L5 and Hold, except rank 7, low compliance bladder. That one is biologically plausible, as it is close to solifenacin’s existing bladder use and has neurogenic detrusor overactivity data (PMID 32007426). It is classed L3 as a research question and is better treated as an extension of the current indication than as true repurposing.
To proceed, the following is needed:
- The SAHPRA package insert (warnings and contraindications), which is needed before any safety screening
- Mechanism of action data from DrugBank
- Any preclinical or clinical study of solifenacin in polycystic kidney or liver disease; without one, this indication should not advance
- Consider redirecting effort to the low compliance bladder prediction
