-Retrospective analysis presented at the 34th International Conference on Pharmacoepidemiology & Therapeutic Risk Management-

CAMPBELL, Calif., Aug. 27, 2018 (GLOBE NEWSWIRE) -- VIVUS, Inc. (NASDAQ:VVUS, the "Company")), a biopharmaceutical company, has reported encouraging data from a retrospective analysis evaluating the cardiovascular safety of Qsymia® (phentermine and topiramate extended-release) capsules CIV.  Results show that the risk of major adverse cardiovascular events (MACE) trended lower in patients taking Qsymia compared with similar patients who were not taking Qsymia.  The results were presented yesterday in a poster at the 34th International Conference on Pharmacoepidemiology & Therapeutic Risk Management, which took place in Prague, Czech Republic, August 22-26.

"The results of this retrospective analysis add to the body of data demonstrating that Qsymia does not increase the risk of MACE," said John Amos, Chief Executive Officer at VIVUS.  "We continue to believe that Qsymia provides patients with significant benefits as a platform for managing body mass index, and our ongoing dialogue with the U.S. Food and Drug Administration includes a label modification request to allow for the safe and effective short-term utilization of Qsymia while significantly reducing or eliminating the requirement for conducting a cardiovascular outcomes study."

Results of the study were presented in a poster titled "Cardiovascular Safety of Phentermine and Topiramate in a United States Claims Database," (Abstract 983/118). The study was a retrospective cohort analysis conducted in MarketScan Commercial Claims and Medicare Supplemental data. The study evaluated MACE rates during periods of exposure to Qsymia, generic phentermine and topiramate combinations (PHEN/TPM) and phentermine (PHEN) or topiramate (TPM) alone, and compared each of these to MACE rates during unexposed periods in former users of these drugs. MACE was defined as a composite of hospitalization for acute myocardial infarction (AMI), stroke, or in-hospital cardiovascular-related death as determined via discharge status and ICD-9-CM diagnoses.

Propensity scores were calculated to adjust for differences in cardiovascular risk factors among the cohorts. Propensity score-adjusted analyses showed that MACE risk trended lower with current Qsymia and PHEN/TPM use compared with the unexposed cohort. Compared to the unexposed cohort, MACE risk was also lower with current PHEN use and higher with current TPM use. The study authors note that the small number of events that occurred during exposure to Qsymia and PHEN/TPM produced considerable statistical uncertainty in the analysis of these cohorts.
