Trial ID Title Status Sponsor Phase Start Date Summary
NCT00140179 ↗ Valnoctamide in Mania Completed Stanley Medical Research Institute Phase 3 2004-09-01 Valproic acid is a leading mood stabilizer for the treatment of bipolar disorder. Its well-known teratogenicity limits its use in young women of childbearing age. According to toxicologic studies the teratogenicity of valproate stems from its free carboxylic group. Valnoctamide is an isomer and an analog of valpromide. Unlike valpromide, valnoctamide does not undergo a biotransformation to the corresponding free acid. It is also likely or at least possible that valnoctamide is anti-bipolar. In mice valnoctamide has been shown to be distinctly less teratogenic than valproate. An injection at day 8 of gestation produced only 1% exencephaly (as compared to 0-1% in control mice and 53% in valproate treated mice). The investigators are performing a double-blind controlled trial of valnoctamide as an anti-bipolar drug. If shown to be anti-bipolar, valnoctamide could be an important valproate substitute for young women with bipolar disorder who are at risk of pregnancy. Patients newly admitted to the Beersheva Mental Health Center may participate if they meet Diagnostic and Statistical Manual of Mental Disorders - 4th edition (DSM-IV) criteria for mania or schizoaffective disorder, manic type. Patients admitted to the study are treated with risperidone at doses of the physicians' discretion beginning with 2 mg daily on days 1 and 2. Valnoctamide or placebo is begun at doses of 600 mg per day (200 mg three times daily) and increased to 1200 mg (400 mg three times daily) after four days. Weekly ratings by a psychiatrist blind to the study drug are conducted using the Brief Psychiatric Rating Scale (BPRS), the Young Mania Rating Scale (YMS), and the Clinical Global Impression (CGI). Weekly blood is drawn for drug levels of valnoctamide to be measured by gas chromatography. Each patient receives valnoctamide or placebo for 5 weeks. Low teratogenic mood stabilizers are a high priority for current research.

NCT00583895 ↗ Safety and Efficacy Study of ImCOOH Cream in Patients Suffering From Moderate Atopic Dermatitis Terminated Valletta Health B.V. Phase 2 2007-12-01 Atopic dermatitis is one of the most common skin diseases, with a lifetime prevalence of up to 20%, and an increasing number of cases. Although there are a variety of treatments the number of specific medications for treating this chronic disease is limited and often not helpful, especially in more severe cases. In addition,most treatments may be used only for a limited period or are less effective in the long term (tachyphylaxis). The development of new compounds is mandatory for treatment of this often chronically recurring disease. The current trial will determine the efficacy, safety and tolerability of the endogenous compound imidazole-4-carboxylic acid (ImCOOH) administered as a topical cream twice daily for 14 days in patients with atopic dermatitis.
NCT00597246 ↗ Imaging Brain Tumors With FACBC and Methionine Completed Memorial Sloan Kettering Cancer Center N/A 2003-05-13 This research protocol makes pictures of brain tumors. The pictures are made with a positron emission tomography (PET) scanner. PET scans use radioactivity to "see" cancer cells. We are using a new kind of PET scan. The new PET scan is called [18F]-FACBC PET. We will compare this to the standard PET scan. The standard PET scan is called [11C]-methionine PET. We expect these pictures will give us information about your tumor. We also hope to collect information about the amount of radioactivity exposure. We will measure radioactivity exposure to your tumor, brain and other organs. The research study results will be used to support the submission of an investigational new drug (IND) application to the Food and Drug Administration (FDA).
NCT00620802 ↗ Pharmacodynamics of CGT 2168 Compared With Plavix® Completed Cogentus Pharmaceuticals Phase 1 2007-11-01 CG106 is a Phase I open-label, randomized, multiple-dose, two-way crossover study to characterize the pharmacodynamics and pharmacokinetics of the investigational fixed-dose combination product CGT 2168 (clopidogrel, 75 mg and omeprazole, 20 mg) relative to Plavix® (clopidogrel, 75 mg). Healthy volunteer subjects will undergo two dosing periods. In each 7-day dosing period, subjects will receive oral doses of study drug consisting of open-label CGT 2168 or Plavix® in the order determined by the randomization schedule. Each period of dose administration will be separated by a two-week washout period. Study exit will occur 1 week after Dosing Period 2. The expected total duration of participation is 8 weeks (56 days), including a screening visit on or within 21 days prior to enrollment. On the day before Day 1 and Day 7 in each dosing period, subjects will be admitted to the Phase I unit. Blood samples to determine ADP-induced platelet aggregation will be collected pre-dose on Day 1 and 2 h after dosing on Day 7. Plasma concentrations of clopidogrel parent and clopidogrel carboxylic acid metabolite will also be measured pre-dose on Day 1 and pre-dose and serially after dosing on Day 7.
NCT00783276 ↗ An fMRI Study of SYN115 in Cocaine Dependent Subjects Completed National Institute on Drug Abuse (NIDA) Early Phase 1 2008-10-01 The dopamine system is critical in modulation of reward and has been implicated in the initiation and maintenance of addiction (Volkow et al 2004). Medications that increase dopamine either directly or indirectly have been shown to have preliminary efficacy at reducing cocaine use in cocaine dependent subjects (Grabowski et al 2004a; Schmitz et al 2008). A novel class of medications that has recently been shown to indirectly modulate dopamine function is adenosine A2A receptor antagonists (Fuxe et al 2007). Based on their effect on dopamine function it has been suggested that these compounds may be efficacious in the treatment of drug addiction (Ferre et al 2007c). Before clinical efficacy studies are undertaken, more basic research on the effects of adenosine A2A antagonists on brain function and behavior are warranted. The aim of this study is to examine the acute effects of a single dose of the selective adenosine A2A antagonist (SYN115, Synosia Therapeutics, Chemical name: 4-Hydroxy-4-methyl-piperidine-1-carboxylic acid-(4-methoxy-7-morpholin-4-yl-benzothiazol-2-yl)-amide) on brain function and behavior in cocaine dependent individuals using functional magnetic resonance imaging (fMRI). To examine the effect of a single dose of SYN115 on brain function and behavior in cocaine dependent subjects. Hypotheses: 1. SYN115 100 mg will increase brain activation in the dorsolateral prefrontal cortex compared to placebo in cocaine dependent subjects performing a working memory task. 2. SYN115 100 mg will increase brain activation in the ventral striatum compared to placebo in cocaine dependent subjects performing a reversal learning task. 3. SYN115 100 mg will reduce brain activation in the anterior cingulate gyrus and amygdala compared to placebo in cocaine dependent subjects performing a cocaine-word Stroop task.

Clinical Trials Update, Market Analysis, and Projection for Omega-3 Carboxylic Acids

Last updated: October 28, 2025


Introduction

Omega-3 carboxylic acids (OM3-CA), a pharmacological formulation derived from omega-3 fatty acids, have garnered significant interest in cardiovascular and lipid management therapeutics. Their unique chemical composition—primarily EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in carboxylic acid form—offers a potential therapeutic advantage over traditional ethyl ester formulations. This analysis consolidates recent clinical trial developments, evaluates the current market landscape, and projects future growth trajectories for omega-3 carboxylic acids.


Clinical Trials Update

Recent Clinical Trials and Outcomes

In recent years, the clinical efficacy profile of OM3-CA has been refined through numerous trials. The pivotal STRENGTH (NCT02179551) trial, conducted by Amarin, sought to assess the efficacy of the drug in reducing major adverse cardiovascular events (MACE) in statin-treated patients with high triglycerides and established cardiovascular disease. Launched in 2014, the trial enrolled over 13,000 participants but was terminated prematurely in 2020 due to a lack of demonstrated benefit over placebo. Despite negative results, the study enriched understanding of omega-3 formulations by highlighting differences between ethyl ester and carboxylic acid forms regarding bioavailability and lipid modulation.

Conversely, the VISTA-IT trial, an ongoing phase III trial, aims to evaluate OM3-CA's impact on reducing triglycerides in patients with severe hypertriglyceridemia (NCT04010518). Early-phase results have demonstrated significant triglyceride reductions (>50%) at higher doses, centering on the drug's lipid-lowering potency. The outcomes are expected to influence regulatory pathways and clinical guidelines.

Regulatory Landscape

The recent submission of supplemental new drug applications (sNDA) from Amarin indicates ongoing efforts to secure regulatory approval in the U.S. and Europe. The FDA has requested additional data on cardiovascular outcomes, reflecting a cautious, evidence-based appraisal. Meanwhile, European regulatory bodies have reviewed post-hoc analyses suggesting favorable effects on triglyceride levels and lipid profiles but have not yet approved OM3-CA explicitly for cardiovascular risk reduction.
