Lantheus Announces Topline Results for BENEFIT 1 LVEF Clinical Trial

February 3, 2020 GMT

NORTH BILLERICA, Mass.--(BUSINESS WIRE)--Feb 3, 2020--

Lantheus Holdings, Inc. (NASDAQ: LNTH) (“Lantheus” or the “Company”), parent company of Lantheus Medical Imaging, Inc. (“LMI”), a leader in the development, manufacture and commercialization of innovative diagnostic imaging agents and products, today announced topline results for the BENEFIT 1 Left Ventricular Ejection Fraction (“LVEF”) clinical trial.

Topline Results for the BENEFIT 1 LVEF Clinical Trial

The BENEFIT 1 LVEF clinical trial is one of two Phase 3, open-label, multicenter studies to evaluate LVEF measurement accuracy and reproducibility of DEFINITY ® contrast-enhanced and unenhanced echocardiography as compared to non-contrast cardiac magnetic resonance imaging (“CMRI”) used as the truth standard. BENEFIT 1 enrolled 145 subjects. The primary objective of this study was to demonstrate improvement in accuracy in measuring LVEF using DEFINITY contrast-enhanced over unenhanced echocardiography as compared to LVEF measured using CMRI.

In BENEFIT 1, there was no statistically significant improvement in the accuracy of LVEF values for contrast-enhanced echocardiography versus unenhanced echocardiography as compared to CMRI. Analyses of the secondary endpoints revealed no improvement in inter-reader variability between the contrast-enhanced and unenhanced echocardiograms for LVEF assessments. A post-hoc analysis, however, did show statistically significant improvements in left ventricular diastolic, systolic and stroke volume measurements with contrast-enhanced versus unenhanced echocardiography when compared to CMRI.

“Although the endpoints for BENEFIT 1 were not met, we will continue to analyze the BENEFIT 1 data,” said Dr. Istvan Molnar, Chief Medical Officer of Lantheus. “When the data from BENEFIT 2 are available, we will compile the data sets to analyze the full results of the trials. We are grateful to the patients, investigators, and trial sites for participating in this trial.”

“DEFINITY is the worldwide leading product in the ultrasound contrast market and it remains a proven and preferred imaging agent serving the echocardiography community within its current indication,” said Mary Anne Heino, President and Chief Executive Officer of Lantheus. “DEFINITY’s consistent year-over-year double digit percentage revenue growth demonstrates the value it continues to provide physicians in diagnosing and managing patients. We are disappointed with the outcome of the BENEFIT 1 trial but we remain fully confident in DEFINITY and the long term growth potential of our microbubble franchise. We will continue to interact with the FDA to enhance the clinical utility for DEFINITY moving forward.”

About DEFINITY®

DEFINITY Vial for (Perflutren Lipid Microsphere) Injectable Suspension is an ultrasound contrast agent for use in patients with suboptimal echocardiograms (see Indications and Important Safety Information below and find full Prescribing Information at www.definityimaging.com ). 1 DEFINITY is engineered to produce small and consistently sized durable microbubbles to fully evaluate the left ventricle. 1 DEFINITY ® has extensive safety experience and a consistent safety profile. 2 Since its launch in 2001, more than 11 million echo studies have been performed with DEFINITY ® and it is the most prescribed contrast agent in the U.S. 3

INDICATIONS

Activated DEFINITY ® (Perflutren Lipid Microsphere) Injectable Suspension is indicated for use in patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border.

CONTRAINDICATIONS

Do not administer DEFINITY ® to patients with known or suspected hypersensitivity to perflutren.

IMPORTANT SAFETY INFORMATION

WARNING: Serious Cardiopulmonary Reactions

Serious cardiopulmonary reactions, including fatalities, have occurred uncommonly during or following perflutren-containing microsphere administration [ see Warnings and Precautions (5.1) ]. Most serious reactions occur within 30 minutes of administration.

  • Assess all patients for the presence of any condition that precludes DEFINITY ® administration [see Contraindications (4)].
  • Always have resuscitation equipment and trained personnel readily available.

In post marketing use, rare but serious cardiopulmonary or hypersensitivity reactions have been reported during or shortly following perflutren-containing microsphere administration [see Adverse Reactions (6)]. The risk for these reactions may be increased among patients with unstable cardiopulmonary conditions [see Adverse Reactions (6.2)]. It is not always possible to reliably establish a causal relationship to drug exposure due to the presence of underlying cardiopulmonary disease.

Please see full Prescribing Information, including boxed WARNING regarding serious cardiopulmonary reactions, on www.definityimaging.com.
