Positive Results for New Clinical Testing The company, which specializes in innovative therapies to treat acute pain, recently reported positive testing outcomes for a new therapy title ARX-04, according to a press release. The drug was tested, along with a placebo, on a total of 163 patients that recently underwent some sort of abdominal surgery, and was found to decrease pain in those treated with the therapeutic. These results were found in both a primary and secondary round of Phase 3 testing, the press release reported. "In addition to the ambulatory surgery setting studied in this trial, we believe ARX-04 has broad application in emergency room and military settings, where patients often do not have immediate access to IV pain medications,” Interim Chief Executive Officer of AcelRx Howie Rosen said. "To that end, we expect to initiate a study this year in emergency room patients. Beyond the ER, we are researching other medically supervised settings in which ARX-04's non-invasive, rapid-acting profile would benefit patients." For more business and financial news, click here.
