Fenofibrate: From Hyperlipidaemia to Cholesterol-Ester Transfer Protein Deficiency
One-Sentence Summary
Fenofibrate is a lipid-lowering drug whose relations recorded in the knowledge graph centre on hypertriglyceridaemia and hyperlipidaemia. The TxGNN model predicts it may be effective for cholesterol-ester transfer protein (CETP) deficiency, but no clinical trials and only 3 preclinical or mechanistic publications support this direction, and none studies the disease itself.

| Evidence Level | L5 |
| Canada Market Status | Marketed (marketed DINs: 10 of 10) |
| Number of DINs | 10 (marketed: 10) |
| Number of approvals | 10 licences (all single-ingredient products) |
| Recommended Decision | Hold |
Why is This Prediction Reasonable?
Detailed mechanism of action data is not available in the data compiled for this report. Based on general knowledge and the submitted literature, fenofibrate is a PPARα agonist that lowers triglycerides and raises HDL cholesterol. The papers provided suggest PPARα agonism upregulates the phospholipid transfer protein (PLTP) gene, which contributes to HDL enlargement in mice.
The link to CETP deficiency is weak. CETP deficiency is a condition in which HDL cholesterol is already markedly elevated and HDL remodelling is impaired. Raising HDL further offers no clear therapeutic rationale and could even be undesirable. The very high TxGNN score most likely reflects network proximity within lipid-metabolism pathways rather than a validated treatment benefit. No fenofibrate-specific clinical evidence in CETP-deficient patients was identified.
Clinical Trial Evidence
Currently no related clinical trials registered.
Literature Evidence
| PMID | Year | Type | Journal | Key Findings |
|---|---|---|---|---|
| 20332533 | 2010 | Preclinical (mouse) | Journal of Cardiovascular Pharmacology and Therapeutics | In human ApoB100/CETP transgenic mice, CETP inhibition (torcetrapib) combined with PPARα agonism (fenofibrate) changed HDL and LDL cholesterol. This is not a CETP-deficiency model. |
| 11342537 | 2001 | Preclinical (mouse) | Journal of Biological Chemistry | Fenofibrate induced the PLTP gene, which accounts for HDL enlargement in treated mice. |
| 30271349 | 2018 | Mechanistic/translational | Frontiers in Physiology | Plasma HDL did not correlate with faecal cholesterol or cholesterol efflux capacity, suggesting HDL function matters more than HDL level. |
None of these studies directly examines CETP deficiency as a disease in patients treated with fenofibrate.

- Many insulin products (human, aspart, degludec, detemir, glargine, glulisine, lispro and others)
- Chenodeoxycholic acid
- Esomeprazole
Please refer to the package insert for authoritative warnings and contraindications, as label text was not available.
Conclusion and Next Steps
Decision: Hold
Rationale: The prediction rests on model score alone. No clinical trials exist, and no cited study addresses CETP deficiency directly. In addition, CETP deficiency already involves high HDL-C, so the expected pharmacological effect is not clearly beneficial.
To proceed, the following is needed:
- Evidence that studies fenofibrate in CETP-deficient patients or a validated disease model
- A clear clinical rationale for any benefit when HDL-C is already elevated
- Detailed mechanism of action data
- Health Canada product monograph warnings, contraindications and indication text, which are missing from the compiled data
