BTG has announced the commencement of the KNOCOUT PE study, which will measure how hospitals and patients are benefitting from a new standard of care in the treatment of pulmonary embolism (PE) utilising EKOS therapy with faster, and even safer protocols, proven effective in the OPTALYSE PE study. The OPTALYSE PE study found PE can be treated effectively with EKOS therapy over a much shorter period and at safer thrombolytic doses far below the previous standard.
