COVID19 | Drug: Icosapent ethyl (IPE) Drug: Placebo | Phase 3 |
Few vaccines have received emergency authorization providing relative immunity, reducing both transmission and infection rates and subsequent associated morbidity and mortality. However, broad access to vaccines is limited globally, and emergence of COVID-19 viral mutations and vaccine breakthrough cases underscore the need for complementary effective therapies.
To date, there are limited systemic options available for effective treatment from viral-inhibitors, polyclonal antibodies (immunomodulatory drugs) to mitigate the inflammatory cascade and subsequent cytokine storm, and low-dose steroids such as dexamethasone in high-risk patients, which was associated with a reduction in mortality.
Icosapent ethyl (IPE) is a safe, well-tolerated oral therapy proven to be effective in improving outcomes in patients with established cardiovascular disease or diabetes with one or more additional risk factors.
In the context of COVID-19, a recent pilot study on 50 patients on a loading dose of 8g/day for three days, followed by 4g/daily showed a significant improvement in validated patient-reported FLU-PRO score symptoms. A corresponding reduction in a key biomarker of inflammation (hs-CRP) was also detected within the IPE arm at 14 days.
While this pilot study provides the first evidence of an early anti-inflammatory effect of IPE, to confirm these findings, we designed a randomized, placebo-controlled study program investigating IPE with a similar loading dose intended to reduce infection rates and subsequent morbidity and mortality among subjects at high risk of infection from SARS-CoV-2 (prevention arm), and to reduce the hospitalization rate and complications in patients with a positive diagnosis of COVID-19 (treatment arm).

Active Comparator: Active treatment
Participants in this arm will receive study medication icosapent ethyl (IPE) with a specific dose scheme.
|
Drug: Icosapent ethyl (IPE)
Participants in this arm will receive study medication IPE with the following dosage schedule: 8 g of IPE (4 capsules every 12 hours - morning and evening, with food) for the first three days followed by 4 g of IPE (2 capsules every 12 hours - morning and evening, with food) thereafter (days 4-28 for treatment arm and 4-60 for prevention arm) Other Name: Vascepa® |
Placebo Comparator: Placebo
Participants in this arm will receive Placebo with the same dose scheme as the active comparator:
|
Drug: Placebo
Participants in this arm will receive placebo with the following dosage schedule: 8 g of placebo (4 capsules every 12 hours - morning and evening, with food) for the first three days followed by 4 g of placebo (2 capsules every 12 hours - morning and evening, with food) thereafter (days 4-28 for treatment arm and 4-60 for prevention arm) |
- (A) Prevention Arm: SARS-CoV-2 positivity assesed up to day 60. [ Time Frame: 60 days ]SARS-CoV-2 positive subjects are defined as subjects with positive tests for SARS-CoV-2 RT-PCR or for SARS-CoV-2 lgG antibodies after developing COVID-19 disease at any stage within the follow-up period (including those subjects with or without symptomatic COVID-19 evaluated before the final visit) or those individuals who test positive for SARS-CoV-2 RT-PCR or for SARS-CoV-2 lgG antibodies at the final visit (day 60).
- (B) Treatment Arm: COVID 19 related hospitalization (indication for hospitalization per the blinded investigator or actual hospitalization) or death assessed up to 28 days [ Time Frame: 28 days ]
- (A) Prevention Arm: High-sensitivity C-reactive Protein (mg/dL) change from baseline to day 60 (key secondary outcome) [ Time Frame: baseline, 60 days ]Mean change from baseline will be computed
- (A) Prevention Arm: Triglycerides (mg/dL) change from baseline to day 60 [ Time Frame: baseline, 60 days ]Mean change from baseline will be computed
- (A) Prevention Arm: FLU-PRO SCORE change from baseline to day 60 in a subset of subjects [ Time Frame: baseline, 60 days ]Mean change from baseline will be computed
- (B) Treatment Arm: COVID 19 related hospitalization or death assessed up to 28 days (key secondary outcome) [ Time Frame: 28 days ]
- (B) Treatment Arm: Alive and out of the hospital at 28 days. [ Time Frame: 28 days ]
- (B) Treatment Arm: In hospital length of stay assessed up to 28 days [ Time Frame: 28 days ]
- (B) Treatment Arm: New requirement of mechanical ventilation assed up to 28 days. [ Time Frame: 28 days ]
- (B) Treatment Arm: Total events: non-fatal myocardial infarction or non-fatal stroke or death (initial and subsequent), until day 28. [ Time Frame: 28 days ]
- (B) Treatment Arm: Total mortality assessed up to 28 days [ Time Frame: 28 days ]
- (B) Treatment Arm: FLU-PRO SCORE change from baseline at 28 days [ Time Frame: (B) Treatment Arm: ]
