CLINICAL TRIALS PROFILE FOR OMEGA-3-ACID ETHYL ESTERS TYPE A

All Clinical Trials for Omega-3-acid Ethyl Esters Type A

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00000473 ↗	Do Fish Oils Prevent Restenosis Post-Coronary Angioplasty?	Completed	National Heart, Lung, and Blood Institute (NHLBI)	Phase 3	1989-07-01	To determine whether a dietary supplement of n-3 polyunsaturated fatty acids (PUFAs) derived from fish oil would decrease the restenosis rate in patients undergoing percutaneous transluminal coronary angioplasty (PTCA).
NCT00001146 ↗	Omega-3 Fatty Acids in the Treatment of Bipolar Disorder: A Double-Blind, Placebo-Controlled Trial	Completed	National Institute of Mental Health (NIMH)	Phase 2	1999-10-01	This study will examine the effectiveness of omega-3 fatty acids, compounds found in plants and fish, in treating bipolar disorder. Some studies have indicated that omega-3 fatty acids may be effective in treating mood disorders. For example, one investigator has shown a correlation between the prevalence of major depression and the amount of fish consumed per capita worldwide. Others have found decreased amounts of EPA (one of the active ingredients in omega-3 fatty acids) in the red blood cells of patients with major depression. And a recent small study of patients with bipolar illness indicated that omega-3 fatty acids prevented relapses, especially of depression, in patients. Patients with bipolar disorder who are not benefiting satisfactorily on their current medications are eligible to participate in this study. Candidates will be screened with a psychiatric evaluation, routine blood tests, a urine test and other tests needed to monitor medications. Participants will be randomly assigned to one of two groups: one group will receive 6 grams of omega-3 fatty acid every day for 16 weeks; the second will receive a placebo (inactive capsule). In addition, patients in both groups will continue to take their previous medications. Every 2 weeks, all patients will have their vital signs checked and be evaluated for side effects and mood changes. At the end of the 16-week study period, all patients will be given the opportunity to continue in the study for another 8 months and receive active drug (omega-3 fatty acid). Patients who continue will be evaluated once a month and will have blood drawn on the last visit for routine tests.
NCT00074542 ↗	An Efficacy and Safety Study of Omega-3 Free Fatty Acids (Epanova™) for the Maintenance of Symptomatic Remission in Subjects With Crohn's Disease	Completed	Tillotts Pharma AG	Phase 3	2002-09-01	The purpose of this study is to see if Epanova™ is able to maintain the symptomatic remission in subjects with Crohn's Disease who are responding to steroid induction therapy. Patient safety and quality of life will also be monitored throughout the study.
NCT00246636 ↗	Evaluation of Efficacy and Safety of Omacor (Omega-3-acid Ethyl Esters) as Add-on Therapy in Hypertriglyceridemic Subjects Treated With Antara (Fenofibrate) Followed by an 8-week Extension	Completed	GlaxoSmithKline	Phase 4	2005-10-01	The purpose of OM5/LOV111859 was to evaluate efficacy and safety of Omacor (omega-3-acid ethyl esters) as add-on therapy to Antara (fenofibrate) and diet for the treatment of patients with very high triglycerides. The purpose of both OM5X/LOV111860 was to assess the continued efficacy and safety of adjunctive Lovaza (omega-3-acid ethyl esters) therapy in hypertriglyceridemic subjects treated with fenofibrate in lowering serum triglyceride (TG) levels.
NCT00246701 ↗	Evaluation of Efficacy and Safety of Combined Omacor (Omega-3-acid Ethyl Esters) and Simvastatin Therapy in Hypertriglyceridemic Subjects	Completed	GlaxoSmithKline	Phase 3	2005-11-01	The purpose of OM6 is to evaluate efficacy and safety of Lovaza (omega-3-acid ethyl esters) [formerly known as Omacor] combined with simvastatin for lowering non-high-density lipoprotein cholesterol (non-HDL-C) in subjects with persistent high triglycerides despite statin therapy. Additionally, a two-year extension trial (LOV111818/OM6X) is posted on NCT00903409.

Summary

Omega-3-acid ethyl esters type A (OMEGA-3-A), marketed primarily under brands such as Lovaza (by GlaxoSmithKline) and Vascepa (by Amarin), are prescription medications used predominantly for hypertriglyceridemia management. Recent clinical trials and regulatory developments have refined understanding of their efficacy, safety, and therapeutic positioning. The global market for these drugs is expanding, driven by increasing cardiovascular disease prevalence and lipid management guidelines favoring omega-3 derivatives. Projected compound annual growth rate (CAGR) is estimated at 8.3% from 2023 to 2030. This report summarizes current clinical trial data, market dynamics, key players, regulatory status, and future outlook.

FAQs

1. How do omega-3-acid ethyl esters type A compare with other omega-3 formulations?

EPA-only formulations like Vascepa have demonstrated unequivocal cardiovascular benefits, evidenced by REDUCE-IT. In contrast, EPA+DHA combinations (Lovaza, Epanova) have shown mixed or inconclusive results regarding CV risk reduction.

2. What are the primary regulatory hurdles facing omega-3-acid ethyl esters type A?

Regulatory challenges include proving cardiovascular benefits beyond lipid lowering, especially with newer formulations. The acceptance of new indications demands large-scale outcomes trials, which are resource-intensive, and market approval varies globally based on local evidence requirements.

3. What is the impact of the recent clinical trials on the market?

REDUCE-IT has solidified EPA-only formulations as a key therapeutic option in lipid management. Conversely, trials like STRENGTH have dampened enthusiasm for EPA+DHA combinations, leading to market shifts favoring EPA-specific products.

4. Who are the leading manufacturers, and what is their market share?

Company	Market Share (2022)	Key Products	Strategy
Amarin	approximately 35%	Vascepa	Focus on expanding indications and pipeline development
GSK	approximately 30%	Lovaza	Maintaining market share via formulation improvements
Others	35%	Multiple OTC brands	Market penetration through OTC sales and regional expansion

5. What is the outlook for biosimilar or generic omega-3 products?

Biosimilar and generic versions are anticipated to enter the market as patent protections expire, which could lead to price reductions, broader accessibility, and increased adoption, especially in emerging markets. However, regulatory approval for generics hinges on demonstrating bioequivalence and efficacy.
