Introduction to Fenofibric Acid
Fenofibric acid, a derivative of the fibrate class of drugs, is widely used to treat severe hypertriglyceridemia, primary hypercholesterolemia, and mixed dyslipidemia. It is marketed under the brand name Trilipix, among others, and is available in various generic formulations.
Clinical Trials and Safety Studies
Current and Ongoing Trials
One of the significant ongoing clinical trials is the Safety Study of Fenofibrate During Pregnancy. This study aims to evaluate the safety of fenofibrate in pregnant women with severe hypertriglyceridemia. The trial involves recruiting 200 pregnant women with triglyceride levels greater than 10 mM, who will be exposed to fenofibrate for more than one week. The study will compare pregnancy outcomes and infant physical growth between exposed and unexposed women. It will also assess the placental transfer and milk penetration of fenofibric acid[4].
Historical Trial Findings
Previous clinical trials have highlighted several key points about fenofibrate:
- Liver Enzyme Elevations: Fenofibrate has been associated with increases in serum transaminases (AST and ALT). In a pooled analysis of 10 placebo-controlled trials, increases to more than three times the upper limit of normal of ALT occurred in 5.3% of patients taking fenofibrate compared to 1.1% of patients on placebo[1].
- Thromboembolic Events: The FIELD trial and the Coronary Drug Project have shown higher rates of pulmonary embolus (PE) and deep vein thrombosis (DVT) in patients treated with fenofibrate compared to the placebo group[1].
- Carcinogenic Potential: Animal studies have indicated an increased incidence of liver carcinomas, pancreatic carcinomas, and other tumors at doses significantly higher than the maximum recommended human dose (MRHD)[1].
Mechanism of Action and Clinical Effects
Fenofibric acid works by activating the peroxisome proliferator-activated receptor alpha (PPARα), which regulates the expression of genes involved in lipid metabolism. This activation leads to:
- Reduced Triglycerides: By increasing the lipolysis and clearance of triglyceride-rich lipoproteins.
- Increased HDL: By enhancing the production of apolipoprotein A-I, a major component of HDL cholesterol.
- Decreased LDL: By reducing the production of apolipoprotein B, a component of LDL cholesterol.
- Other Effects: Fenofibrate also reduces fibrinogen levels and serum uric acid levels, which can be beneficial in managing cardiovascular risk factors[3].
Market Analysis and Projections
Global Market Trends
The global fibrate drugs market, which includes fenofibric acid, is expected to grow significantly over the forecast period.
- Market Size and Growth: The market was valued at US $2.84 billion from 2018 to 2022 and is projected to reach US $4 billion by 2029, with a Compound Annual Growth Rate (CAGR) of 5% from 2023 to 2029[3].

Fenofibric Acid Market Specifics
The fenofibric acid market is thriving due to several factors:
- Increasing Demand: The growing prevalence of dyslipidemia and the need for effective lipid-lowering therapies drive the demand for fenofibric acid.
- Generic Availability: The availability of generic versions of fenofibric acid from multiple manufacturers, such as AbbVie, Actavis, Alembic, and others, has increased accessibility and reduced costs, contributing to market growth[2].
- CAGR Projection: The global fenofibric acid market is expected to expand at a CAGR of +4% over the forecast period from 2019 to 2025[5].
Distribution and Availability
Fenofibric acid is available in various formulations, including delayed-release capsules.
- Brand and Generic Options: It is marketed under the brand name Trilipix and is also available in generic forms from several manufacturers, including AbbVie, Actavis, Alembic, Aurobindo Pharma, and others[2].
- Strengths: The drug is available in strengths of 45 mg and 135 mg fenofibric acid equivalent[2].
Side Effects and Safety Considerations
While fenofibric acid is generally well-tolerated, it has several notable side effects and safety considerations:
- Liver Enzyme Elevations: As mentioned, fenofibrate can cause significant increases in liver enzymes, necessitating regular monitoring and potential discontinuation if levels persist above three times the normal limit[1].
- Thromboembolic Events: There is an increased risk of pulmonary embolus and deep vein thrombosis associated with fenofibrate therapy[1].
- Carcinogenic Potential: Animal studies have shown an increased incidence of certain tumors, although the clinical significance in humans is not fully established[1].
Patient Resources and Professional Guidelines
For patients and healthcare professionals, it is crucial to be aware of the following:
- Dosage Information: Fenofibric acid should be taken as directed, usually once daily with a meal, to minimize gastrointestinal side effects[2].
- Pregnancy and Lactation: The safety of fenofibrate during pregnancy is being evaluated in ongoing studies. However, it is generally recommended to use caution and consider alternative treatments if possible[4].
- Interactions: Patients should be aware of potential interactions with other medications and inform their healthcare providers about all medications they are taking[2].
Key Takeaways
- Clinical Trials: Ongoing studies are evaluating the safety of fenofibrate in pregnant women and its long-term effects.
- Mechanism of Action: Fenofibric acid works by activating PPARα, leading to improved lipid profiles.
- Market Growth: The global fibrate drugs market, including fenofibric acid, is expected to grow significantly over the next few years.
- Safety Considerations: Regular monitoring of liver enzymes and awareness of thromboembolic risks are crucial.
- Availability: Fenofibric acid is available in both brand and generic forms, enhancing accessibility.
