Currax Pharmaceuticals LLC (“Currax”) today announced the results of a Cardiovascular Health Outcomes Analysis (HOA). The results showed there is no evidence of excess cardiovascular risk and no statistically significant difference in major adverse cardiovascular events (MACE) between CONTRAVE?/MYSIMBA? and the comparator group.(1) The study, presented by Dr. Dustin Burns at the International Society for Pharmacoepidemiology (ISPE) conference, held August 24-28th in Berlin, Germany, included more than 24,600 people with an average follow-up of four and a half years.

“The study's results found no evidence of increase in cardiovascular risk among initiators of CONTRAVE, which is informative for healthcare providers and patients considering this treatment option for obesity,” said Dustin Burns, Ph.D., GStat, the presenting author and Senior Managing Scientist at Exponent who led the analysis.

These results are consistent with the four previous randomized clinical trials, the previous LIGHT Trial, and more than ten years of post-marketing safety surveillance data with over 700,000 patient years of product usage. These study results help to substantiate the cardiovascular safety profile of CONTRAVE/MYSIMBA and the ongoing INFORMUS trial. 

In addition, the ongoing INFORMUS trial will address the regulatory post-marketing commitments and further characterize the long-term cardiovascular safety for patients taking CONTRAVE/MYSIMBA. In January 2024, the first patient was enrolled in the INFORMUS trial, and to date there are over 1,800 patients randomized.

"We are honored to have Dr. Burns present these favorable findings at ISPE,” Michael Kyle, M.D., SVP Chief Medical Officer of Currax Pharmaceuticals said. “Achieving this milestone and the affirmation of the cardiovascular safety of CONTRAVE is gratifying. Over the past four years, we worked exhaustively with regulatory agencies to fully characterize the cardiovascular safety of the product and these results are another proof-point of the positive benefit-risk of CONTRAVE/MYSIMBA.”

About CONTRAVE/MYSIMBA

CONTRAVE, also marketed as MYSIMBA in the European Union and European Economic Area, is an extended release fixed dose combination of naltrexone and bupropion (naltrexone HCL/bupropion HCL) indicated as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults with an initial body mass index (BMI) of 30 kg/m2 or greater (obese), or adults with a BMI of 27 kg/m2 or greater (overweight) with at least one weight-related medical problem such as high blood pressure, high cholesterol, or type 2 diabetes.

About the INFORMUS Trial  

The INFORMUS Trial (NB-CVOT3) is a Phase IV, multi-center, prospective, randomized, pragmatic, double-blinded, placebo-controlled study intended to capture cardiovascular (CV) outcomes during real-world use of naltrexone/bupropion (CONTRAVE). Randomization will occur 1:1 between CONTRAVE and placebo. The primary endpoint includes comparison of major adverse cardiovascular events (MACE) between study subjects receiving CONTRAVE and subjects receiving placebo.
