Pravastatin: From Hyperlipidemia and Atherosclerosis to Homozygous Familial Hypercholesterolemia
One-Sentence Summary
Pravastatin is a statin (HMG-CoA reductase inhibitor) originally used for hyperlipidemia, atherosclerosis and stroke-related conditions. The TxGNN model predicts it may be effective for Homozygous Familial Hypercholesterolemia, but the supporting evidence is indirect: 1 clinical trial (which tests a different drug) and 12 publications (mostly reviews of other lipid-lowering agents).
Quick Overview
| Item | Content |
|---|---|
| Original Indication | Hyperlipidemia, atherosclerosis, stroke and cerebrovascular disorders (the FDA licence records have no indication text, so this comes from the knowledge-graph indication list) |
| Predicted New Indication | Homozygous familial hypercholesterolemia |
| TxGNN Prediction Score | 99.95% |
| Evidence Level | L4 |
| US Market Status | Cancelled only (all 5 listed ANDAs are cancelled) |
| Number of NDAs | 5 (all ANDAs, all cancelled) |
| Recommended Decision | Hold |
Why is This Prediction Reasonable?
Detailed mechanism-of-action data is not available in the data compiled for this report. Pravastatin is a well-known HMG-CoA reductase inhibitor. It lowers LDL cholesterol by reducing hepatic cholesterol synthesis and upregulating LDL receptors, and it has an established role in hyperlipidemia and atherosclerosis.
Familial hypercholesterolemia is a closely related lipid disorder, so the TxGNN prediction is biologically plausible. There is an important caveat, however. Homozygous FH is characterized by severe LDL receptor deficiency, and statin efficacy depends on residual receptor activity. One review in the data states that statins are not very effective in homozygous FH. The expected benefit is therefore likely limited compared with heterozygous FH.
Clinical Trial Evidence
| Trial Number | Phase | Status | Enrollment | Key Findings |
|---|---|---|---|---|
| NCT03510715 | Phase 3 | Completed | 18 | Open-label alirocumab study in children and adolescents (8–17 years) with HoFH. It does not test pravastatin and provides disease context only. |

Safety Considerations
Package insert warnings and contraindications were not available in the data compiled for this report, so please refer to the package insert for authoritative safety information.
- Knowledge-graph contraindication signals (not label text): kidney disease, liver disease, gallbladder disease, myopathy and other muscle disease, rhabdomyolysis, thrombocytopenia, peptic ulcer disease, gout, hemophilia, anemia, nephrolithiasis, hypercalcemia, and others. These should be verified against the label.
- Drug Interactions: 100 interactions were identified. The moderate-level ones listed include metronidazole, clarithromycin, eluxadoline, naltrexone, pectin, rosuvastatin, simvastatin and tinidazole. Combining pravastatin with other statins (rosuvastatin, simvastatin) deserves particular attention.
Conclusion and Next Steps
Decision: Hold
Rationale: The prediction score is high, but the only linked trial tests a different drug (alirocumab), and the literature does not directly evaluate pravastatin in homozygous FH. Statins are also expected to have limited efficacy in this disease because of LDL receptor deficiency. All US licences are cancelled, and the label safety data is missing.
To proceed, the following is needed:
- Pravastatin-specific efficacy data in homozygous FH patients (for example, LDL-C response in receptor-negative vs receptor-defective patients)
- Comparison with established HoFH therapies
- Package insert warnings and contraindications from the FDA label
- Mechanism of action data and clarification of the market and licensing situation
Other predictions of note: Two other predictions have more substantial evidence. Familial hypercholesterolemia (heterozygous; L2, with pediatric pravastatin pharmacokinetic and randomized studies) and HIV-associated dyslipidemia (L2, with a Phase 3 fenofibrate-vs-pravastatin trial and several Phase 4 trials) are better candidates for follow-up. Both are about positioning within an established drug class rather than true repurposing.
