DUBLIN, Ireland and BRIDGEWATER, N.J., Nov. 13, 2020 (GLOBE NEWSWIRE) — Amarin Corporation plc (NASDAQ:AMRN) today announced the presentation of REDUCE-IT^® CABG at American Heart Association’s (AHA) Virtual Scientific Sessions 2020, being held virtually from November 13 – November 17, 2020, adding to the growing body of knowledge on the clinical impact of VASCEPA^® (icosapent ethyl). These new analyses supported by Amarin were presented by Subodh Verma, M.D., Ph.D., FRCSC, Professor and Cardiac Surgeon at University of Toronto.

“The REDUCE-IT CABG analysis results are another piece of the puzzle when looking at the potential use of icosapent ethyl in the procedural setting,” commented Dr. Deepak L. Bhatt, M.D., M.P.H., Executive Director of Interventional Cardiovascular Programs at Brigham and Women’s Hospital and Professor of Medicine at Harvard Medical School, principal investigator of REDUCE-IT. “The findings of benefit in at-risk patients with prior CABG are consistent with previously presented data on overall reductions in first and total coronary revascularization events, as well as in patients with prior percutaneous coronary interventions, and further strengthen the case for consideration of icosapent ethyl as an additional intervention for use by physicians to care for this patient population.”

The REDUCE-IT CABG analysis examined 1,837 (22.5%) of the patients enrolled in REDUCE-IT, representing all patients who had undergone a prior coronary artery bypass grafting (CABG) procedure, a common form of surgical intervention to help treat coronary heart disease. Baseline characteristics were similar among patients randomized to VASCEPA versus placebo. Post hoc exploratory analyses of this subgroup showed that, for the composite endpoint of 5-point MACE, which was the prespecified primary endpoint for the full REDUCE-IT study cohort, time to first event was significantly reduced with VASCEPA versus placebo by 24% (p=0.004) and total (first and subsequent) events were also reduced by 36% (p=0.0002). For the REDUCE-IT study’s key secondary composite endpoint of 3-point MACE, time to first event was reduced by 31% (p=0.001) in the subgroup of patients with a prior CABG.

Coronary revascularization procedures, such as CABG, are invasive, carry multiple risks, and can have significant direct and indirect costs. Patients with elevated triglycerides despite statin therapy have increased risk for ischemic events, including coronary revascularizations. These procedures, whether pre-scheduled or performed in an emergency, inevitably result in additional time spent in a healthcare setting. The latest statistical update from the American Heart Association (AHA) shows that, in 2014, an estimated 371,000 inpatient CABG procedures were performed in the United States with a mean inpatient hospital charge for CABG of $168,541.¹

“Revascularization procedures overall significantly impact the healthcare system, with CABG procedures adding to the burden and driving substantial costs,” said Steven Ketchum, Ph.D., senior vice president and president, research & development and chief scientific officer, Amarin. “The subgroup data presented at AHA Virtual Scientific Sessions 2020 suggests another way in which VASCEPA can possibly alleviate the significant burden that at-risk patients and the healthcare system face with CABG procedures and how VASCEPA therapy can potentially reduce the risk of dangerous subsequent events.”  

REDUCE-IT was not specifically powered to examine individual cardiovascular endpoints or patient subgroups, therefore p-values presented for these revascularization analyses are nominal and exploratory with no adjustment for multiple comparisons. In addition, coronary revascularization as an endpoint can sometimes be considered subjective; however, these endpoints were adjudicated by an independent, blinded clinical endpoint committee. Results from the total coronary revascularization events analyses are consistent across the various recurrent event statistical models and are also consistent with the first coronary revascularization events results. Together, the REDUCE-IT first and total coronary revascularization events results support the robustness and consistency of the clinical benefit of VASCEPA therapy in reducing coronary revascularization.

These REDUCE-IT CABG results follow multiple scientific presentations of analysis results from other important patient subgroups in the REDUCE-IT study, including REDUCE-IT REVASC² and REDUCE-IT PCI. References to these other subgroup analyses are available on Amarin’s website at www.amarincorp.com.

About Cardiovascular Risk

The number of deaths in the United States attributed to cardiovascular disease continues to rise. There are 605,000 new and 200,000 recurrent heart attacks per year (approximately 1 every 40 seconds), in the United States. Stroke rates are 795,000 per year (approximately 1 every 40 seconds), accounting for 1 of every 19 U.S. deaths. Cardiovascular disease results in 859,000 deaths per year in the United States.¹ In aggregate, there are more than 2.4 million major adverse cardiovascular events per year from cardiovascular disease or, on average, one every 13 seconds in the United States alone.

Controlling bad cholesterol, also known as LDL-C, is one way to reduce a patient’s risk for cardiovascular events, such as heart attack, stroke or death. However, even with the achievement of target LDL-C levels, millions of patients still have significant and persistent risk of cardiovascular events, especially those patients with elevated triglycerides. Statin therapy has been shown to control LDL-C, thereby reducing the risk of cardiovascular events by 25-35%.³ Significant cardiovascular risk remains after statin therapy. People with elevated triglycerides have 35% more cardiovascular events compared to people with normal (in range) triglycerides taking statins.^4,5,6

About REDUCE-IT^®

REDUCE-IT was a global cardiovascular outcomes study designed to evaluate the effect of VASCEPA in adult patients with LDL-C controlled to between 41-100 mg/dL (median baseline 75 mg/dL) by statin therapy and various cardiovascular risk factors including persistent elevated triglycerides between 135-499 mg/dL (median baseline 216 mg/dL) and either established cardiovascular disease (secondary prevention cohort) or diabetes mellitus and at least one other cardiovascular risk factor (primary prevention cohort).

REDUCE-IT, conducted over seven years and completed in 2018, followed 8,179 patients at over 400 clinical sites in 11 countries with the largest number of sites located within the United States. REDUCE-IT was conducted based on a special protocol assessment agreement with FDA. The design of the REDUCE-IT study was published in March 2017 in Clinical Cardiology.⁷ The primary results of REDUCE-IT were published in The New England Journal of Medicine in November 2018.⁸ The total events results of REDUCE-IT were published in the Journal of the American College of Cardiology in March 2019.⁹ These and other publications can be found in the R&D section on the company’s website at www.amarincorp.com.

About
VASCEPA

^®

(icosapent ethyl) Capsules

VASCEPA (icosapent ethyl) capsules are the first-and-only prescription treatment approved by the FDA comprised solely of the active ingredient, icosapent ethyl (IPE), a unique form of eicosapentaenoic acid. VASCEPA was initially launched in the United States in 2013 based on the drug’s initial FDA approved indication for use as an adjunct therapy to diet to reduce triglyceride levels in adult patients with severe (≥500 mg/dL) hypertriglyceridemia. Since launch, VASCEPA has been prescribed over eight million times. VASCEPA is covered by most major medical insurance plans. The new, cardiovascular risk indication for VASCEPA was approved by the FDA in December 2019.

Indications and Limitation of Use

VASCEPA is indicated:

• As an adjunct to maximally tolerated statin therapy to reduce the risk of myocardial infarction, stroke, coronary revascularization and unstable angina requiring hospitalization in adult patients with elevated triglyceride (TG) levels (≥ 150 mg/dL) and
  • established cardiovascular disease or
  • diabetes mellitus and two or more additional risk factors for cardiovascular disease.
• As an adjunct to diet to reduce TG levels in adult patients with severe (≥ 500 mg/dL) hypertriglyceridemia.

The effect of VASCEPA on the risk for pancreatitis in patients with severe hypertriglyceridemia has not been determined.

Important Safety Information

• VASCEPA is contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to VASCEPA or any of its components.
• VASCEPA was associated with an increased risk (3% vs 2%) of atrial fibrillation or atrial flutter requiring hospitalization in a double-blind, placebo-controlled trial. The incidence of atrial fibrillation was greater in patients with a previous history of atrial fibrillation or atrial flutter.
• It is not known whether patients with allergies to fish and/or shellfish are at an increased risk of an allergic reaction to VASCEPA. Patients with such allergies should discontinue VASCEPA if any reactions occur.
• VASCEPA was associated with an increased risk (12% vs 10%) of bleeding in a double-blind, placebo-controlled trial. The incidence of bleeding was greater in patients receiving concomitant antithrombotic medications, such as aspirin, clopidogrel or warfarin.
• Common adverse reactions in the cardiovascular outcomes trial (incidence ≥3% and ≥1% more frequent than placebo): musculoskeletal pain (4% vs 3%), peripheral edema (7% vs 5%), constipation (5% vs 4%), gout (4% vs 3%), and atrial fibrillation (5% vs 4%).
• Common adverse reactions in the hypertriglyceridemia trials (incidence >1% more frequent than placebo): arthralgia (2% vs 1%) and oropharyngeal pain (1% vs 0.3%).
• Adverse events may be reported by calling 1-855-VASCEPA or the FDA at 1-800-FDA-1088.
• Patients receiving VASCEPA and concomitant anticoagulants and/or anti-platelet agents should be monitored for bleeding.

Key clinical effects of VASCEPA on major adverse cardiovascular events are included in the Clinical Studies section of the prescribing information for VASCEPA as set forth below:

Surrogate Preserved Cardiac Function in Disease Model, Slowing Progression

BRISBANE, Calif., Nov. 13, 2020 (GLOBE NEWSWIRE) — MyoKardia, Inc. (Nasdaq: MYOK) today presented clinical and non-clinical data related to mavacamten, MyoKardia’s investigative therapeutic in late-stage development for the potential treatment of hypertrophic cardiomyopathy (HCM), at the American Heart Association’s Scientific Sessions 2020. Three poster presentations were made available detailing exploratory analyses from Myokardia’s Phase 3 EXPLORER-HCM study of mavacamten for the treatment of obstructive HCM and from the Phase 2 MAVERICK-HCM study of mavacamten in patients with non-obstructive HCM, as well as non-clinical results of a mavacamten surrogate compound in a large animal model.

“These data add detail to the emerging picture of mavacamten’s beneficial impact on the HCM heart, including improvements in cardiac pathophysiology, diastolic function and biomarkers of disease progression,” said Jay Edelberg, M.D., Ph.D., MyoKardia’s Chief Medical Officer. “HCM is characterized by the thickening of the heart muscle and constraints on diastolic filling. Having repeatedly demonstrated that mavacamten can have a profound effect on reducing the obstruction of the left ventricular outflow tract in HCM, echocardiography data from our EXPLORER-HCM trial show that in just 30 weeks of treatment, mavacamten is gradually bringing measures of cardiac structure closer to a normal state, improving parameters of diastolic function and reducing biomarkers of disease. We are optimistic that these changes may ultimately point to the benefits of mavacamten treatment in the progression of HCM.”

Mavacamten Favorably Impacts Key Pathophysiologic Processes in Obstructive Hypertrophic Cardiomyopathy: Results From the EXPLORER-HCM Study

An exploratory analysis from the Phase 3 EXPLORER-HCM clinical trial of mavacamten for the potential treatment of symptomatic, obstructive HCM investigated the changes from baseline to Week 30 on specific measures of the heart’s structure and function using serial echocardiograms (ultrasounds of the heart).

• Treatment with mavacamten led to statistically significant reductions in left ventricular mass (LVMI), indicating that mavacamten is having an effect on cardiac structure. LVMI has been shown to be a predictor of HCM-related mortality.
• Mavacamten treatment improved left ventricular relaxation (which in turn led to improved cardiac filling pressures). Statistically significant improvements (p<0.0001 for difference from placebo) were achieved across diverse echocardiographic measurements of diastolic function (LA volume index, lateral e’, lateral E/e’, septal e’, and septal E/e’).
• Significantly more mavacamten-treated patients achieved resolution of mitral valve systolic anterior motion (SAM) compared to placebo (80.9% vs. 34.0%; p<0.0001), and 9% achieved resolution of mitral regurgitation (MR) in the mavacamten group vs. none in placebo (p=0.0006). SAM and MR may cause or contribute to obstruction of the left ventricular outflow tract and are known to impact cardiac performance and increase risk of serious cardiovascular complications, such as arrhythmias.
• Mavacamten treatment resulted in significant reductions in cardiac biomarkers of myocardial wall stress and injury compared to placebo. Specifically, there was an 80% greater reduction in NT-proBNP and a 41% greater reduction in cardiac troponin in the mavacamten treatment group vs. placebo.
• Patients with the highest degree of obstruction at baseline achieved greater improvements in echocardiographic parameters and biomarker reductions.

Accelerometer-measured Activity in Non-obstructive Hypertrophic Cardiomyopathy: Patient-generated Activity Measures Correlate With, and are Convolutional Neural Network Predictors of, Clinical Parameters in the MAVERICK-HCM Study

MyoKardia’s Phase 2 MAVERICK-HCM study of mavacamten was the first study to examine quantitative levels of activity in a non-obstructive HCM patient population. As part of the MAVERICK-HCM study, patients were asked to wear ActiGraph GT9X Link wrist-worn monitors for up to 14 days between screening and day 1 and between weeks 12 and 16 to record daily activity. A multitask convolutional neural network (CNN) trained on raw accelerometry, was also used to jointly predict clinical markers of HCM severity.

Markers of physical activity drawn from accelerometry, including average daily accelerometer units (ADAUs) and step count, were associated with standard clinical markers of HCM severity. Out the 59 patients enrolled in MAVERICK-HCM, 50 patients wore the accelerometer for ≥1 compliant day. Patients in MAVERICK-HCM averaged 3,000 steps per day. Results from the accelerometry exploratory analyses showed that higher physical activity correlated with key clinical markers of HCM, including exercise capacity as measured by peak VO2, changes in NT-proBNP levels, and improvements in patient reported outcomes using the Kansas City Cardiomyopathy Questionnaire (KCCQ), indicating that accelerometry measures may be a useful indicator of drug activity. CNN predictions of clinical measures from activity data found strong correlations for pVO₂, NT-proBNP, KCCQ score, and E over e prime. These findings indicate that deep learning models can be constructed to predict markers of HCM severity from patients’ raw accelerometry data.

Chronic Treatment With A Mavacamten-like Myosin-modulator (MYK-581) Prevents Left-atrial Remodeling, Decreases Cardiac Troponin Leakage, And Blunts Mortality In A Mini-pig Model Of Inherited Hypertrophic Cardiomyopathy

Results from an in vivo study in a genetic mini-pig model of HCM showed that chronic administration of a mavacamten-like myosin-modulator blunted chronic cardiac troponin-T leakage and decreased mortality, both characteristic of HCM progression in this non-obstructive model. In addition, chronic treatment also reduced left-ventricular and prevented left-atrial remodeling, preserving normal left-atrial size as well as atrial myofibrillar structure and function. Taken together, these non-clinical observations provide additional evidence of mavacamten’s activity beyond the reduction of LVOT obstruction and support the emerging clinical evidence of mavacamten’s beneficial effects on overall cardiac structure in the HCM heart.

IRVINE, Calif., Nov. 13, 2020 (GLOBE NEWSWIRE) — Inari Medical, Inc. (NASDAQ: NARI) (“Inari”), a commercial-stage medical device company focused on developing products to treat and transform the lives of patients suffering from venous diseases, today announced follow-up results of the first 230 patients enrolled in its FLASH study.  FLASH is a real world registry to study the FlowTriever system in intermediate- and high-risk pulmonary embolism (“PE”) patients.  The results were strongly positive.  Just one death (0.4%) was reported at 30 days.  By contrast, the national PERT Consortium^® Quality Database recently showed 30-day mortality rates of 25.9% and 6.1% for high- and intermediate-risk PE patients.  In addition, the FLASH Registry showed a readmission rate of 6.7%, compared to the nearly 25% readmission rate shown in the PERT Database.  Efficacy data were equally compelling, showing normalization or near normalization in a battery of hemodynamic variables like pulmonary artery pressure, RV/LV ratio, and heart rate, as well as dyspnea (shortness of breath) metrics.   

FLASH is a 500-patient prospective, multicenter, single-arm registry evaluating real world patient outcomes after treatment of PE with FlowTriever. Interim data were obtained across 19 US sites, and results were presented virtually by National Principal Investigator, Catalin Toma, MD, Director of Interventional Cardiology at UPMC Heart & Vascular Institute in Pittsburgh, PA at the American Heart Association (“AHA”) Scientific Sessions 2020.

These data follow the presentation of equally compelling acute data from the same patient set delivered two weeks ago at the annual TCT meeting.  The acute results showed, at 48 hours, no deaths, no cardiac injuries, no pulmonary injuries, no procedure-related clinical deteriorations, and no intracranial hemorrhages in this highly compromised PE patient population.  The TCT data also showed clinically and statistically significant improvement in hemodynamic parameters while the patient was still on the table.  Post-procedure median ICU stay was 0 days.  The new FLASH data released at AHA extends the study follow-up period to 30 days and demonstrates the durability of these acute results with continued improvement in outcomes over time.

“FLASH has shown us that PE patients experience symptom relief and improved cardiac function immediately upon removal of significant clot burden.  These outcomes continue to improve over time.  In fact, for a high percentage of these patients, measurements for dyspnea, right heart strain, pulmonary artery pressure and heart rate actually normalized after FlowTriever thrombectomy.  We believe this suggests that removal of large clot burden with the FlowTriever system not only has an important impact acutely, but might have an important positive effect on long term implications of PE, like CTED and CTEPH,” said Dr. Toma.

“With over 60% of patients in FLASH having no contraindication to lytics, the study data suggests that FlowTriever is emerging as a frontline therapy for intermediate and high-risk PE patients, regardless of patient eligibility for other treatment options.  PE care pathways are evolving,” said Thomas Tu, MD, Chief Medical Officer of Inari Medical. “Venous thromboembolism (“VTE”) patients are central to everything that we do at Inari, and we remain committed to advancing the treatment of this disease through clinical research and the continued development of purpose-built devices.”
